The topography of the lot varies from flat in the central and northern portions to very steep in the south. The steep slopes may be as steep or steeper than 30% and there is more than 20 feet of vertical elevation gain. The north side of the lot is bounded by a class 1 wetland. This wetland is a salt water marsh. Based on the above findings, it is determined that there are potentially two types of critical areas on or adjacent to the site.• A Critical Areas Study is required to delineate the boundaries of these potential critical areas, their buffers and setbacks. For the steep slopes, a licensed surveyor must create a topographic map of the site which indicates all areas which slope 30% or more and have a vertical gain of 20 feet or more within the 30% slopes. The map must also show the location of the steep slope buffers and setbacks. For the wetland, a qualified wetland biologist shall physically delineate the boundaries of the wetland. Then a licensed surveyor working with the biologist must create a map identifying the boundary of the wetland, the boundary of the buffer and the boundary of the buffer setbacks. All critical areas studies shall be performed as three party agreements with the city selecting the consultant and the property owner or applicant paying the fees. If the property owner wishes to apply for a specific development permit which they feel would not impact the critical areas located on the site, they may submit their proposal to the Planning Department for review. If the Planning Department finds that the proposed development permit will not adversely impact a critical areas or its buffers, a conditional waiver may be issued on a project by project basis.

The ESC will govern relevant procedures during remediation activities as well as the proposed site development at the subject property (Drawing 1). In general, we have designed a comprehensive field and monitoring program to assure protection of the area during the field remedial activities. Elements of this plan comply with the requirements of the Local Soil Conservation Districts, ' King County Storm Water Manual and Standards of Soil Erosion and Sediment Control in the State of Washington. 1.2 PURPOSE AND APPLICABILITY ' The purpose of the ESC presented herein is to describe procedures and methods for preventing environmental impacts during the excavation of soil impacted with total petroleum hydrocarbons ' (TPH) as part of the overall remedial action. The area of land being disturbed by excavation activities is less than 1 acre. To accomplish this objective, the project team has designed a comprehensive field program to minimize erosion and sedimentation as well as to protect surface ' water and shallow localized groundwater quality from excessive sediment loading and petrochemical related contamination. The specific chemical contaminants of concern are TPH (as gasoline) and benzene, toluene, ethylbenzene, and xylene (BTEX) at concentrations above the Model Toxics Control Act (MTCA) Method B cleanup levels. The analytical data presented in the Remedial Investigation Report presents results of findings from soil and water sampling conducted in 1998. The primary concern regarding environmental protection and stormwater pollution is to inhibit pollutants and minimize sediments from entering the stormwater system that ultimately is discharged to nearby waterways. The program is designed to re -direct surface water runoff around the area of impacted soil material. This process will prevent stormwater sheet -flow from carrying sediments and other potential contaminants off -site. The project team will achieve their P:\9077.001\004\UNOCAL EROSION SED.2PLAWFARED.DOC Page 3 of 9 II' objectives by using a combination of properly placed silt fences, portable aboveground storage tanks (Baker Tanks), sediment traps, and plastic covering. In addition, Best Management .' Practices (BMPs) will be used during the course of the overall project. The remaining sections of this plan presents procedures for preventing and/or minimizing the release of pollutants and excess sediments to the environment during the course of the remedial action and site development (see attached City of Edmonds Standard Detail). 1.3 SITE DESCRIPTION AND EXISTING STORMWATER DRAINAGE SYSTEM W 1.3.1 Site Description and ESC Devices I' The subject property occupies approximately 2 1/2-acre situated in the lower yard of the former Unocal Terminal (Drawing 1). The separate plan depicting ESC devices and limits of the proposed disturbed areas are listed in Drawing 1. This remedial action has been designed to ' address the presence of approximately 5,000 cubic yards (approximately 7,500 tons) of affected soil located in the lower yard. The affected soil contains petroleum products related to the ' former operations at the Unocal Fueling Facility. 1.3.2 Perimeter Control & Protection Devices of Adjacent Areas ' The area of the proposed remediation will occur on the western portion of the subject property (Drawing 1). In general, the petroleum -impacted soil will be removed to a depth of 2 feet below ' the shallow groundwater surface. Based on information presented by Unocal Corporation, we anticipate the shallow groundwater surface to be encountered at depths ranging from 7 to 8 feet bgs. Staging areas will be constructed near each excavation on the southeasterly portion of ' excavations A and B, northeasterly portion of excavations C and D (Drawing 2). 1.3.3 Existing & Proposed Contours The locations where the proposed remediation will occur are generally flat. Any slope or contour ' that exists in the general vicinity of the lower yard slopes away from Deer Creek and the tidal pool. Berms will be constructed with clean overburden material and placed along the perimeters ' of the excavations to route surface water away from excavations. 1.3.4 Location of Construction Entrance and Detail As shown on Drawing 3-1, the primary construction entrance is off a private road, Unoco Road, on to Pine Street. Trucks traveling to the site will travel north on State Route SR-104 making a P:\9077.001\004\UNOCAL EROSION SED.2PLANWARED.DOC IPage 4 of 9 left turn on to Pine Street, and then a right turn on to Unoco Road into the Unocal Terminal. Traveling away from the construction site will require one flagger with trucks traveling on to Pine Street leaving the job site. Woodway residents traveling down Pine Street will have advance -warning signs (Flagger Ahead). This will allow safe access of trucks leaving the site. The entrance and the drive entering the facility are paved. The entrance and drive. will be regularly swept during remedial activities. 1.3.5 Identification of Drainage Features The proposed remediation area is generally flat. Portions of the proposed construction site are covered with asphalt and concrete, and most places are cover with crushed rock surfacing. Presently site surface water flows to the center of the lower yard to catch basins and from those to an oil water separator. Site drainage is then discharged to Deer Creek and on to Puget Sound. Discharge from the Unocal oil water separator is made available under NPDES Discharge Permit No. WA-003186-1. 1.3.6 Slope & Cut Description As shown on Figure 2, cut slopes of each of the 4 excavations will be at maximum 1 to 1 slope and minimum of 2 to 1. Since these are considered shallow excavations no indication of top/bottom slope catch lines were included. 1.4 CONVEYANCE SYSTEM The lower yard conveyance system is comprised of 14 catch basins, with 8", 10" and 12" pipe all taking drainage to an API oil water separator. During heavy rainfall conditions surface water can be diverted to a 5 acre impound basin. The estimated surface area surrounding the 4 excavations is approximately 1 acre. All drainage within the lower yard is contained and transmitted by way of underground piping. Some surface run-off can enter the impound basin and outfall pond directly, but this runoff is separate and occurs away from the excavations and stockpile locations. No swales, cut-off trenches, ditches or bypass piping take surface water off -site from the lower yard. 1.5 EROSION AND SEDIMENTATION MANAGEMENT PROCEDURES Erosion and Sedimentation Control management procedures will include engineering controls designed to: inhibit a potential negative impacts on the environment and pubic health, provide a safe environment for site workers, prevent off -site exposure that would adversely affect human health and welfare, and minimize nuisances to the surrounding areas. Engineering controls (i.e., P:\9077.001\004\UNOCAL EROSION SED.2PLANWARED.DOC Page 5 of 9 BMPs) will be implemented for the management of stormwater, liquids generated by site activities, dust, vapor and odors. The BMPs will include: • Sediment and erosion controls (i.e., installation of silt fencing); • Runoff management. • Preventative maintenance; • Good housekeeping; • Spill prevention and response procedures; Inspections; 1.5.1 Stabilization of Exposed Areas The only exposed areas that will be created during this work are the side walls and floors associated with each excavation. . The side walls will be sloped into each excavation and any erosion will be captured within each respective excavation. When the soil removal and free product removal associated with this- project are complete, the excavations will be backfilled. Sedimentation that occurs from erosion of the side walls will be incorporated into the backfill and will not be removed from the excavation. Stabilization of the exposed excavation areas using BMPs (e.g., sodding, hydroseeding, plastic covering) is not necessary or applicable. The City of Edmonds should allow for an exception to the minimum requirements to stabilize the exposed excavation areas consistent with Section 18.30.065 of the City of Edmonds code. 1.5.2 Other Measures to Limit Sediment Impacts All open excavations, trenches and embankments will be protected to the extent practical from surface water run on and nun off. Protective measures will include barriers, berms and waterproof coverings. Soil erosion and sediment controls will be inspected after each rain event, and any repairs required will be performed immediately. Filter fabric will be installed in catch basins in the areas surrounding the lower yard excavations. The filter fabric will be installed by removing the grating and laying a piece of filter fabric over the opening. The grating will then be placed over the filter fabric to hold it in place. Filter fabric will be installed so that it completely covers the catch basin entrance and will not allow short circuiting of run-off around the, fabric. If the filter fabric becomes clogged or tears it will be replaced. P:\9077.001\004\UNOCAL EROSION SED.2PLANMFARED.DOC Page 6 of 9 1.5.3 Soil Stockpile Run-on/Runoff Management The uncontaminated soil and petroleum contaminated soil (PCS) stockpiles will be placed on concrete/asphalt ground -covered surface areas on the southeastern portion of the site (Figure 4). The stockpiles will be bermed with hay bails and covered with waterproof sheeting. Due to space limitations, petroleum -impacted soil will likely be loaded directly into trucks and transported to Evergreen Recyclers Seattle, Washington. On —site personnel will closely monitor the truck loading activities to minimize the tracking of soil onto the nearby roadways. The asphalt pavement in this area will be sweep clean. If pavement sweeping is not affective at minimizing the tracking of sediments on the roadway, a gasoline powered street sweeping unit will be used. Silt fencing will be placed along the westerly edge of excavation `A'. In addition, silt fencing will be placed around the perimeter of the stockpiled soil if deemed necessary. In general, the asphalt and concrete groundcover will remain in -place as much as possible to reduce potential sedimentation. 1.5.4 Excavation de -watering Control & Containment Two 1,000-gallon temporary aboveground water storage tanks will be placed adjacent to the excavation area. The tanks will be connected in series. The first tank will be for settling of suspended sediments, the second tank will be for discharge, and water quality sampling. A secondary method will utilize an in -excavation weir and vacuum truck system. Water will be discharged to the storm water system consistent with the requirements of Unocal's NPDES permit, pending the receipt of analytical results. 1.5.5 Dust Control Dust may be generated during soil excavation and grading, transportation of soils, material stockpiling, stabilization, and placement of backfill materials. A water trailer with a 1 '/2 hose will be used to mitigate fugitive dust. Additionally, the Unocal Terminal has water cannons that can assist in suppressing dust. Climatic and soil moisture conditions currently at the subject property indicate dust generation during normal construction/ excavation activities will not be a significant problem. 1.5.6 Dirt Control The exit driveways are currently covered with concrete and asphalt. To minimize tracking of dirt and other materials onto adjacent roadways, the trucks will be loaded on clean gravel surfaces adjacent to B, C and D excavations. Adjacent to excavation A, near the southeastern portion of P:\9077.001\004\UNOCAL EROSION SED.2PLANMFARED.DOC Page 7 of 9 ' that site, is covered with asphalt (Drawing 1). The existing roadways will be monitored for tracking of dirt or other materials that have been spilled, washed, tracked or otherwise deposited ' onto the roadway. When such materials are noted they will be promptly removed and placed onto the PCS stockpile. A laborer will be on site during working hours to monitor this process. ' As stated above , if pavement sweeping is not affective at minimizing the tracking of sediments on the adjacent roadways, a gasoline powered street sweeping unit will be used. ' 1.5.7 On -Site Personnel Training Training of all on site personnel will be conducted prior to implementation of the field program ' relative to erosion and sediment control issues. In addition as part of the construction quality control (CQC) program, prior to initiation of each new phase of work, the CQC manager will ' conduct a site meeting to discuss the erosion and sediment control issues for each new task with all affected personnel. 1.5.8 Inspections and Maintenance The CQC manager for compliance with the ESC will conduct an inspection of the erosion and ' sediment control measures on a daily basis. Inspections will include looking at each catch basin insert, silt fence, berm, stockpile cover, and other erosion and sediment control measures covered ' by this plan. If during the daily inspection it is determined that a BMP is not functioning properly (e.g., water running under a silt fence) or it is damaged (e.g., hole in a silt fence) then it ' will be repaired as soon as possible. If repairing an existing BMP will not rectify an observed problem, then the CQC manager will notify Unocal's project manager and provide recommendations to rectify the issue. Upon approval of CQC manager's recommendations from Unocal's project manager, steps will be taken to implement the approved procedures as needed. 1.5.9 Sedimentation and Erosion Processes Typical construction activities can often result in enhancing or initiating sedimentation and erosion processes. The result of such processes can result in increase sedimentation to adjacent waterways and/or bodies of water as well as existing storm water runoff and wastewater treatment systems. We have identified several factors influencing sedimentation and erosion processes, which may be encountered during implementation of the remedial action. These factors include: • Vehicle and heavy equipment traffic; • Soil excavation and stockpiling activities; • Importation, placement and compaction of clean backfill; P:\9077.001\004\UNOCAL EROSION SED.2PLANMFARED.DOC Page 8 of 9 Dust control measures. 1.6 CONSTRUCTION SEQUENCE Please refer to the attached schedule along with the following items: 1.6.1 Pre -construction Meeting A pre -construction meeting will be held on.

II. INTRODUCTION A. Application 1. Applicant: Triad Point Edwards LLC (Property Owner: Unocal Corporation) 2. Site Location: 11720 Unocal Road, generally known as the UNOCAL tank farm (see vicinity map, Attachment 1) 3. Request: Establishment of "undisturbed soil' contours for the purpose of determining height calculations for future structures (see Attachments 2 and 3). 4. Review Process: Planning Staff makes an administrative decision, appealable to the Hearing Examiner. Major Issues: a. Compliance with Edmonds Community Development Code (ECDC) Section 21.105.010, definition of "undisturbed soil." b. Compliance with Edmonds Community Development Code (ECDC) Section 20.95, staff review requirements. B. Decision Based upon the Findings of Fact and Conclusions, Attachments and Exhibits submitted with the application, the City of Edmonds Planning Division issues the following decision: For the subject property, the contours and topographic map to be used to determine "undisturbed soil' for the purposes of calculating height of future structures are those described in the following report: Edmonds Unocal Tank Farm Undisturbed Ground Study and Request for Consideration, prepared by Gregers F. Krabbe, PE, of Triad Associates, dated December 14, 2001. FINDINGS OF FACT AND CONCLUSIONS A. Site Description 1. Site Development, Neighboring Development, And Zoning: a) Facts: (1) Size and Location: The subject property consists of approximately 22.9 acres of land in the southwest corner of the city, generally west of SR-104, south of the Port of Edmonds and the Edmonds marsh, and adjacent to the northern boundary of the Town of Woodway. (2) Land Use: The property is the site of the former Unocal oil tank farm. The site in question is the upland hillside portion of the Unocal property, sometimes referred to as the "upper yard." (3) Zonin : The zoning of the subject property is Commercial Waterfront (CW) (see Attachment 1). (4) Terrain and Vegetation: The subject property consists of a disturbed hillside, generally sloping downward from the Woodway town limits toward SD-2001-201.doc / January 8, 2002 / Staff Report File No. SD-2001-201 Page 3of 7 the north. The site was dominated by the former Unocal oil tank farm (recently demolished), while portions of the site are wooded. 2. Surrounding Development and Zoning: a) Facts: (1) North and West: Beyond the base of the slope is the "lower yard" of the Unocal property, with the city's Marina Beach Park to the west, the Port of Edmonds to the northwest, and the Edmonds marsh to the northeast. Zoning is CW — Commercial Waterfront (Unocal and Port properties) or OS — Open Space (marsh). (2) South: Single family homes are directly south within the Town of Woodway. B. Edmonds Community Development Code (ECDC) Compliance 1. ECDC Section 21.105.010 (definition of "undisturbed soil"). a) Facts: (1) The ECDC defines two terms, "height" and "undisturbed soil," as follows: 21.40.030 Height. Height means the average vertical distance, from the average level of the undisturbed soil of the site covered by a structure, to the highest point of the structure.... `Average level' shall be determined by averaging elevations of the downward projections of the four comers of the smallest rectangle which will enclose all of the building, excluding a maximum of 30 inches of eaves. If a corner falls off the site, its elevation shall be the average elevation of the two points projected downward where the two sides of the rectangle cross the property line. 21.105.010 Undisturbed soil. Undisturbed soil means the condition of the site at the time a building permit application is made to the city, before any site work occurs. However, where the site has been altered by grading, cutting, or filling or similar activities before the application for a building permit, the building official shall make the determination from then available data of the mean elevation of the undisturbed soil. If the undisturbed soil elevation is not readily determined due to demolition of an existing structure, the contours may be reconstructed by the building official to coincide with adjoining topography to determine the undisturbed soil elevations. If the proposed structure occurs where no setbacks are required, the elevation of the surface (sidewalk, alley, or soil) of the property line at or nearest the intersection of the sides of the building height rectangle will be considered undisturbed soil. Where the building official deems it necessary, he shall have the right to require establishment of a datum point from which all height.measurements shall be made. SD-2001-201.doc / January 8, 2002 / Staff Report File No. SD-2001-201 Page 4of 7 (2) Unocal Corporation has submitted an engineering study entitled Edmonds Unocal Tank Farm Undisturbed Ground Study and Request for Consideration, prepared by Gregers F. Krabbe, PE, of Triad Associates, and dated December 14, 2001 (see Attachment 4 for an excerpt and summary). The study attempts to reconstruct the original undisturbed topography of the site by examining historical information, reviewing existing contours that still exist in the vicinity, and analyzing the composition of soils on the site. The study constructs a contour map derived from a total of 18 radial cross sections through the site. This contour map (included as Figure 6 in the study) depicts the derived "undisturbed soil" for the purposes of applying the ECDC definitions of "undisturbed soil" and "height" when the city reviews plans for future structures when the site is redeveloped. b) Conclusions: (1) The referenced study takes a multi -dimensioned approach to analyzing the topography of the site, and _appears to be a reasonable interpretation of historical information combined with data taken from on -site soils examinations and the existing topography of nearby undisturbed slopes. 2. Compliance with Edmonds Community Development Code (ECDC) Section 20.95, staff review requirements. a) Facts: (1) This application is related to a potential development project of undetermined nature. However, because the request is site -specific, the application is being considered as a staff decision with public notice required. All public notice requirements are being complied with, including mailing to adjacent properties within 300 feet, a legal notice placed in the newspaper, and posting of notices on -site. b) Conclusions: (1) The requirements of ECDC Section 20.95 have been met. C. Technical Committee a) Facts: (1) No comments were received from other city departments. (2) The city contracted with Reid Middleton Inc., an engineering consultant, to review the Krabbe study. The Reid Middleton review concluded that the contours presented in the study are "a reasonable interpretation of the data." (See Attachment 5) D. Consistency with Comprehensive Plan: 1. Comprehensive Plan Policies a) Facts: (1) The city's Comprehensive Plan contains policies related to development and topography. Although a specific development application has not yet been made for the subject property, the plan policies do make it clear that SD-2001-201.doc / January 8, 2002 / Staff Report File No. SD-2001-201 Page Sof 7 development should be related to the topography of the site. In as much as the subject application seeks to clarify what the "undisturbed" contours of the site are, this will assist in making future development proposals be in keeping with the topography of the site, and hence in compliance with city policy. The following Comprehensive Plan policies apply: [from Land Use: Soils and Topography] B. Goal. Future development in areas of steep slope and potentially hazardous soil conditions should be based on site development which preserves the natural site characteristics in accordance with the following policies: B.1. Large lots or flexible subdivision procedures, such as PRD's, should be used in these areas to preserve the site and reduce impervious surfaces, cuts and fills. B.2. Streets and access ways should be designed to conform to the natural topography, reduce runoff and minimize grading of the hillside. C. Goal. Development on steep slopes or hazardous soil conditions should preserve the natural features of the site, in accordance with the following policies: C. 1. Grading and Filling. C. La. Grading, filling, and tree cutting shall be restricted to building pads, driveways, access ways and other impervious surfaces. C.1.b. Grading shall not jeopardize the stability of any slope, or of an adjacent property. C.l.c. Only minimal amounts of cut and fill on hillsides exceeding 15- slope should be permitted so that the natural topography can be preserved. Fill shall not be used to create a yard on steeply sloped property. C. Ld. Fill and excavated dirt shall not be pushed down the slope. C.2. Building Construction. C.2.a. Buildings on slopes of 15% or greater shall be designed to cause minimum disruption to the natural topography. C.2.b. Retaining walls are discouraged on steep slopes. If they are used they should be small and should not support construction of improvements which do not conform to the topography. C.2.c. Water detention devices shall be used to maintain the velocity of runoff at predevelopment levels. b) Conclusions: (1) The proposal is consistent with the Comprehensive Plan. E. Environmental Assessment: 1. An environmental checklist under the State Environmental Policy Act (SEPA) is not required for this application. SD-2001-201.doc / January 8, 2002 / Staff Report File No. SD-2001-201 Page 6of 7 F. Critical Areas Review: 1. Critical Areas Review number: CA-1994-0180 2. Results of Critical Areas Review: A critical areas study was completed in June, 1995, analyzing wetland and slope conditions on the Unocal property. III. RECONSIDERATIONS AND APPEALS The following is a summary of the deadlines and procedures for filing reconsiderations and appeals. Any person wishing to file or respond to a recommendation or appeal should contact the Planning Department for further procedural information. A. Request for Reconsideration Section 20.095.050.B.2 allows for planning staff to reconsider their decision if a written request is filed within ten (10) working days of the posting of the notice required by this section. The reconsideration request must cite specific references to the findings and/or the criteria contained in the ordinances governing the type of application being reviewed. B. Appeals Section 20.095.050.B.3 describes how appeals of a Staff decision shall be.made. The appeal shall be made in writing, and shall include the decision being appealed along with the name of the project and the date of the decision, the name of the individual or group appealing the decision, their interest in the matter, and reasons why the appellant believes the decision to be wrong. The appeal must be filed with the Community Development Director within fourteen (14) calendar days after the date of the decision being appealed. C. Time Limits for Reconsideration and Appeals The time limits for Reconsiderations and Appeals run concurrently. If a request for a reconsideration is filed before the time limit for filing an appeal has expired, the time "clock" for filing an appeal is stopped until a decision on the reconsideration request is completed. Once the staff has issued his/her decision on the reconsideration request, the time clock for filing an appeal continued from the point it was stopped. For example, if a request is filed on day 5 of the appeal period, an individual would have 9 more days in which to file an appeal after the staff issues their decision on the reconsideration request. IV. NOTICE TO COUNTY ASSESSOR The property owner may as a result of the decision rendered by the staff request a change in the valuation of the property by the Snohomish County Assessor's Office.

City of Edmonds 121— 5m Ave. North Edmonds WA 98020 RECEIVEE) December 14, 2001 PERMIT COUNTER Hand Delivered Re: Unocal upper yard at Point Edwards; request for staff decision Dear Mr. Chave: I am the attorney for Triad Point Edwards LLC ("Triad"). Triad is reviewing the feasibility of redeveloping a portion of certain property owned by Union Oil Corporation of California ("Unocal") at Point Edwards in the City of Edmonds, commonly known as the "upper yard" ("Subject Property"). The Subject Property is legally described on Schedule 1 attached. In connection with its reviews of the Subject Property, Triad is requesting a staff decision by your department under Edmonds Community Development Code ("ECDC") § 20.95.050, Staff Decision —Notice Required, as more fully outlined below and in the accompanying materials. In addition to Schedule 1, the following materials are enclosed: City of Edmonds Development Information form dated December 14, 2001 for the requested staff decision, signed by me on behalf of Triad and by Carl G. Kellar for. Unocal; 2. Four (4) sets of the engineering report entitled "Edmonds Unocal Tank Farm Grading Study and Request for Consideration" dated December 14, 2001 ("Engineering Report"), prepared by Gregers F. Krabbe, PE, Triad Associates, the consulting engineers for the project; 3. Chicago Title Insurance A.L:T.A. Commitment for title insurance Order No. 366419 dated October 17, 2001, and Supplemental thereto dated December 14, 2001, showing Unocal's ownership of the Subject Property; . 4. Copy of a letter to you dated December 14, 2001 from Mr. Kellar confirming, among other things, Unocal's ownership of the Subject Property and its authorization to Triad to take this action; and 600 MAIN STREET, SUITE E • EDMONDS, WASHINGTON 98020 PHONE: (425) 673-9591 • FAX: (425) 673-0631 Mr. Robert Chave, Planning Manager December 14, 2001 Page 2 5. Triad's check made payable to the City of Edmonds in the amount of $255.00, the stated fee for the requested action and surcharge. Unocal acquired the Subject Property in the early 1920's and developed it as a bulk fuel terminal and storage facility. This use continued until approximately 1991 when the fuel storage tanks located on the site were decommissioned The site currently is undergoing environmental review and cleanup. The fuel storage tanks located on the site were demolished by Unocal . earlier this year. The topography of much of the Subject Property has been substantially altered over the 80-year period of Unocal's ownership and use. As part of its site assessment, Triad needs to establish the appropriate elevations to be used for purposes of height calculations under ECDC § 21.40.030. This code section provides, in pertinent part, that "Height means the average vertical distance, from the average level of the undisturbed soil of the site covered by a structure, to the highest point of the structure ..." (emphasis supplied). Triad interprets "level of the undisturbed soil" to refer to the original elevations for the site before it underwent development by Unocal. It is Triad understands that this interpretation is consistent with your department's position and with the City's historic interpretation of its development code. In addition to the plain language of the referenced code section, the current City of Edmonds Development Information publication, "Height Calculation Information", states that "Height must be calculated prior to any on -site grading or alteration of the property," and directs applicants to determine the maximum permitted height on a site by using a specified averaging method with a baseline elevation "at original, undisturbed soil". Triad's objective is to determine these baseline elevations for the site so that appropriate height calculations can be made. For undeveloped sites or undisturbed portions of property, this is a direct and relatively easy surveyor's calculation. For parcels that have undergone substantial regarding, alteration and disruption, existing topography may not accurately represent "original, undisturbed" soil elevations. This is the case with the Subject Property. In order to approximate original grade as closely as possible, it is necessary to reconstruct the topography of the site as it likely existed before development activity commenced. Triad commissioned Triad Associates (no affiliation) to assess these issues and, if possible, to develop an acceptable methodology to reconstruct the original, undisturbed grade of the Subject Property to a reasonable, "best engineered" standard. Mr. Krabbe spearheaded this effort. Triad Associates conducted field inspections and reviewed relevant historic information and aerial photos, offite and offsite soils data, soils quantification studies, surrounding topography, and other appropriate information, and developed an engineering model of the undisturbed topography of the Subject Property. Triad Associates' analysis, methodology, findings, and conclusions are set forth in the Engineering Report. 1 refer you to the Report for the particulars of the technical processes utilized in this assessment and for Triad Associates' professional judgments. Mr. Krabbe has certified the results of the study as a "best engineered" reconstruction of the original, undisturbed topography of the Subject Property. 0 " 0 Mr. Robert Chave, Planning Manager December 14, 2001 Page 3 Based on the Engineering Study, Triad respectfully requests your determination, as Planning Manager, that the reconstructed topography of the Subject Property established by Triad Associates, is an approved representation of the "level of the undisturbed soil" for all purposes of calculating permitted heights of structures that may be proposed by Triad for the Subject Property, and that Edmonds Community Development Code § 21.40.030 be interpreted and applied to the Subject Property accordingly. In addition to the materials and information submitted to you under cover of this letter as part of Triad's application for staff review and decision, we intend to provide the following supplementary information as soon as it is available to us: 1. The street address information required for notice of the staff decision by the director of development services under ECDC §§ 20.95.050(B)(1) and .20.91.010(B)(1)(a)(ii); and 2. A review of relevant decisions and precedent of the City of Edmonds hearing examiner, architectural design board, or other departments, agencies, or staff of the City relating to the interpretation and application of ECDC § 21.40.030 in cases involving other sites with disturbed soil levels. We believe that the materials submitted to you with this letter will enable you to begin your review of the Engineering Report immediately. Extra copies of the Engineering Report have been included to facilitate distribution to other City departments as may be needed, and to any outside engineering consultant retained by the City to assist in the requested review. If you have questions about these materials, the request for staff review and decision under this letter, or related considerations, or if there is any further information that you require in order to process Triad's request and render a decision, please so advise. We appreciate the opportunity to make this submission and look forward to your decision. Very truly yours, Richard E. Gifford Enclosures cc: Frederick W. Grimm Ross W. Wood Greg F.

Unocal submits this letter in support of the request made on behalf of Triad Point Edwards LLC for a staff decision by the Planning Division of the Development Services Department, City of Edmonds. Triad's request was made by letter to you dated December 14, 2001 from its attorney, Richard E. Gifford. Triad is requesting a staff decisiodestablishing the undisturbed soil levels of the site for purposes of making height calculations under Edmonds Community Development Code § 21.40.030, Height. Triad's request is based on the engineering analysis and methodology described in the report entitled "Edmonds Unocal Tank Farm Undisturbed Ground Study and Request for Consideration" ("Engineering Study") prepared for Triad by Greg Krabbe of Triad Associates . ("Triad Engineers'). The Engineering Report accompanied Mr. Gifford's submittal to you on behalf of Triad. Unocal has been supplied with, and has reviewed, a complete copy of the Engineering Study as submitted to you, including all supporting materials and attachments. The descriptions and assumptions contained in the Engineering Study are true and justifiable to the best of Unocal's knowledge based on its ownership, development, and use of the.site as a bulk fuel terminal and storage facility over the last eight decades. As recounted in the Engineering Study, the site has been substantially altered and regraded over this period -of time and, in its current condition, the terrain does not represent the original, undisturbed soils levels for the much of the site. Mr. Krabbe's analysis and methodology as described in the Engineering Study are consistent to the best of our knowledge with Unocal's historic development and use of the site. Unocal agrees with Triad Engineers' conclusion that the reconstructed undisturbed grade of the site as modeled in the Engineering Study, is a reasonable and logical determination of the predevelopment, undisturbed level of the soils since original engineering design dating back to the early 1920s is not available. Accordingly, Unocal concurs with the conclusions stated in the Engineering Study. Further, Unocal supports and consents to Triad's request that your department issue a staff decision confirming that the reconstructed site topography represents the "level of the undisturbed soil" of the site for purposes of calculating heights of structures in connection with any proposed redevelopment of the site. On behalf of Unocal, I have signed the City of Edmonds land use application form being submitted on Triad's behalf in connection with its request for a staff decision, expressly authorizing Triad to take this action with respect to the Subject Property and authorizing the City of Edmonds and its staff to enter the site for posting and inspections attendant to its review of the requested action.

Prepared For: Point Edwards LLC December 11, 2001 Attachment 4. #01 Unocal Tank Farm undisturbed ground study 1 1 Executive Summary ' This report outlines the engineering consideration used to establish a true undisturbed ground line for the upper yard or "tank farm" of the Unocal site located ' in The City of Edmonds. This study was undertaken in order to evaluate ' development constraints in relation to the City's height limitations for structures, which require the "undisturbed" ground elevation be used as the baseline measurement. I . Data used to establish the undisturbed ground elevation is as follows: • Historical photos ' • Onsite soils logs g • Evaluation of surrounding topography ' • Earthwork quantity evaluation ' Offsite soils logs It was assumed that the original 1920'S site design was conceived to minimize the amount of mass grading done to the site. Original ground was estimated in disturbed areas by creating cross sections of the existing ground and adding planes projected through points known to be ' undisturbed. These points were identified using historic photos, soils logs taken 12/14/01 Page A•1 Job #01027 TRIAD Unocal Tank Farm undisturbed ground study ' onsite, and field observation. The resulting adjusted sections were then checked against regional maps for consistency with surrounding topography. The reconstructed topography was then compared to the existing site to calculate an ' estimate of excavation cut and fill material. This analysis provided estimates of 70,000 CY of cut, and 30,000 CY of fill. Based on review by the Geotechnical ' engineer, it is assumed that the excess material generated from the original grading of the site was either pushed over the embankment or transported to the lower yard ' and used as fill material. ' The resulting topography is a best, engineered estimate of original undisturbed grade for the subject site, and can be used to calculatebuilding height limitations per ' City of Edmonds code. F7 'J 1 1 12/14/01 Page A-2 .lob #01.027 ARLAD ' essociwr r:s 1 Unocal Tank Farm undisturbed ground study 2 Introduction ' The subject site lies at the far southwest corner of The City of Edmonds, between Unoco Rd. And Pine St., abutting the city limits of Woodway, just at the apex of ' Edwards Point, and is commonly known as the Unocal "Tank Farm". Photographs of the site are included in section 3.1 of this report. Site topography is rolling to ' steep with slopes between 2% and 75%. Soils are identified as native sands, silty sand, sandy silt and laminated to massive silt and clay in the Geotechnical report (See appendix, Terra Associates Project No. T-4893, Preliminary Geotechnical ' Report, Unocal site,10/21/01). Unocal Corporation, the current owner, began site development in the early 1920's as a buuc fuel terminal, with 23 above ground storage tanks ultimately located on the subject parcel, and a facilities yard on the parcel below. Construction was ' accomplished in phases; the first phase was completed in the early 1920's and consisted of the construction of 14 storage tanks on the subject parcel. The second ' phase consisted of the construction of 6 additional tanks on the subject parcel p 1 p e and ' occurred sometime in the early 1950's. The remaining 3 tanks were built subsequent to 1955. All storage facilities have been decommissioned by Unocal, and demolished in the summer of 2001. In its current state, the site is substantially cleared and graded with areas of steep terrain left undisturbed. 1 As a first step toward redevelopment of the site, City of Edmonds height restrictions ' for structures must be considered in order to evaluate potential building types. Edmonds Community Development code, section 21.40.030 establishes the baseline ' for building height calculations as "the average level of the undisturbed soil of the site". Because the tank farm site has been substantially altered as a part of the ' development process, the original, undisturbed topography can only be reconstructed by reference to available historic information and engineering ' analysis. This study was performed in order to establish a model of the undisturbed 12/14/01 Page A•3 Job #01.027 ARLAD IS' nc IIT FS . Unocal Tank Farm undisturbed ground study ground topography of this site for use as the baseline measure in making height calculations. Analysis was based on the creation. of a series of cross sections through the site. ' Undisturbed ground lines were estimated using onsite points and grades established as undisturbed. Contour lines were then drawn through elevations established by the cross sections to produce a best engineering approximation of the original topography. ' 3 Establishment of Original Ground Elevations Even with the historic grading of the site, there are still significant indicators of ' where original undisturbed grade had been: ' • Perimeter areas left undisturbed ' • Soils logs indicating evidence of topsoil layers reminiscent of the original ground surface 3.1 Undisturbed areas ' It has been generally stated that the top of the site, located inside of Pine St, and the ' steep perimeter have not been disturbed by Unocal's past development or use of the site (See figure 1). These conclusions have been verified by site inspection and ' review of a series of aerial photographs of the site taken in 1947,1955 and 1967. 1 12/14/01 Page A-4 Job #01:027 /TRIAD ' A�FQCI ATII X", I Unocal Tank Farm undisturbed ground study ' These photos show virtually no change in the vegetation at the peak or perimeter of the site, indicating that these areas are in their original, undisturbed condition. This ' further substantiates our professional determination that they represent undisturbed grade. ' 3.2 Soils Logs Soils logs contained in the geotechnical report (See appendix) note where topsoil was observed in the strata. Specifically, logs 3,4,6,7,8,9 and 15 (See figure 1.) have ' traces of organic soils immediately below the fill materials identified onsite. This is "old noted as the top soil horizon' and has been interpreted as an indicator of where ' the original ground surface was prior to construction of the tank farm. Logs containingevidence of original ound are scattered throughout the site, and give �' g ' additional references for calibrating the estimated undisturbed ground line interior to the site, within the perimeter conditions described above. 4 Creation of Cross sections ' In order. to construct a contour map re that is resentative of the undisturbed P ' topography, created cross sections need to be frequent enough throughout the site to present an adequate number of data points. For this site, a total of 18 sections were taken radial from a central point along the .west boundary, spaced every 100' along an alignment bisecting the site (See figure 2). Cross sections were created by first establishing an existing ground profile along the section to be evaluated. The undisturbed ground line was then projected from the undisturbed perimeter or end grades, and through soil log data exhibiting signs of ' the old topsoil horizon located in the interior of the site. Undisturbed ground lines were adjusted between known data points using the following assumptions: 12/14/01 Page A-8 Job #01.027 AMAD Unocal Tank Farm undisturbed ground study • Equipment available during the time of the original site excavation did not allozn for the massive site adjustments zne are familiar with today. We assume that the original ' 1920's grading concept was designed to minimize excavation. This assumption is applied to the western most 60 % of the site. The eastern section of the site was ' constructed in approximately 1950, when excavation equipment had evolved to the ' point where massive earth movement was more economical (See 1955 photo). • With the benefit of better earthmoving equipment, it is assumed -that more massive excavations can be expected in the eastern half of the site (See 1955 Photo). ' • It is assumed that grades located between tank pad excavations and berms are likely to be undisturbed (this assumption is collaborated by soil logs in several locations). • In order to minimize compaction requirements and to assure sound bearing strength ' for tank foundations, it is assumed that tank pad excavations themselves zvere formed entirely in cut, slightly keyed into the ground on the downhill side. Figures 3 and 4 are examples of the resultant cross sections showing both existing gu P g g ground and reconstructed undisturbed ground lines. These were constructed using existing topographic data and the undisturbed ground data and assumptions ' explained above. 1 5 Creation of undisturbed contour lines ' Contours representing the reconstructed undisturbed ground topography were created by setting points every 25' along each section line at the elevation of the iestimated undisturbed ground line. A Triangulated Irregular Network (TIN) between these points was using the Land Development Desktop R2i design ' software. From the TIN, lines of equal elevation between the cross sections were identified as topographic contour lines. 1 12/14/01 Page A-9 J°e #01.027 ARLAD \ C I AT II Unocal Tank Farm undisturbed ground study The resulting topographic map was then compared to regional topography as represented by the USGS Quadrangle maps. The map for this area (See figure 5, USGS City of Edmonds Quadrangle) indicates steep slopes against the Puget Sound shoreline, and more gradual eroded slopes within the draw east of the site and along ' its northern border. The site itself is shown as a gradual transition from the steep P shoreline condition along the west coast to the milder terrain on the interior draw, which is consistent with both the reconstructed and undisturbed topography. 'As a second check of the create topography, earthwork estimates we re done by ' subtracting the undisturbed topography from the existing. Results indicate a total of 70,000 CY of cut, and 30,000 CY of fill. Wasting of extra material during construction was probably done through a combination of pushing material over the embankment, and transporting fill ' material into the lower section, or "lower yard" of the Unocal site. It is assumed that the amount of material wasted over the embankment was not significant enough to disturb the larger trees in these steep areas. Review of the aerial photos clearly ' shows a graded connection between the subject site and the lower yard, and consequently the potential to transport material. In addition, soil logs taken in the ' lower yard indicate the presence of fill material. consistent with that found on the subject site. ' 6 Conclusion The undisturbed ground topography predicted by this analysis indicates elevation adjustments ranging from increases of 2' to 25' in the areas of extensive grading activity directly associated with the construction of the storage tanks. Grade ' adjustments in surrounding areas are minimal, and consist of both increases and ' decreases of the current elevations, or, no changes in areas where original ground elevations are believed to remain. 12/14/01 ' Job #01.027 ARAD`fOf IAT F.� Page A• 10 Unocal Tank Farm undisturbed ground study 1 These results do not represent radical alterations of the existing ground elevation favorable to evaluation of the City's height code, but are modest adjustments ' consistent with the assumptions made in the analysis, which reflect common construction practices. To the extent possible, this analysis has been substantiated by historic information, ' or current data believed to be similar to original site conditions. Results were checked against the following: • Surrounding topography • Construction practice ' • Geotechnical data I• Earthwork calculations ' In addition, this study has been prepared with the supervision of a series of professionals with experience in civil engineering, geotechnical engineering (See ' appendix), surveying / mapping and construction practice. As such, we believe the "undisturbed ground topography" predicted by this study is a reasonable, best engineered estimate of the site topography prior to construction, and meets the City's criteria for establishing the undisturbed ground elevation cited in code 21-040.030. 12i14i01 ARLAD Page A-11 Job #01.027 . -IIOCIITES Unocal Tank Farm undisturbed ground study 7 Appendix 7.1 Geotechnical letter 7.2 Figures 7.2.1 Figure 1.

ENVIRONMENTAL CHECKLIST Purpose of checklist: The State Environmental Policy Act (SEPA), chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring -preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply." Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Use of chw1distfor nonproject proposals: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

City of Edmonds Grade and Fill Permit City of Edmonds Critical Areas Checklist WA Department of Ecology NPDES Permit 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) Pursuant to chapter 173-340 WAC, Model Toxics Control Act (MTCA), Unocal proposes to perform interim remedial actions to reduce potential threats to human health and the environment and to provide additional information for a feasibility study and subsequent design of a cleanup action for the site. Specifically, petroleum -contaminated soil will be removed from the upper yard area of the Terminal and shipped off site for thermal treatment or disposal; heavy -metal -contaminated surface soil will be removed from areas of the upper and lower yard and shipped off site for disposal; and free petroleum product and associated petroleum contaminated soil will be -removed from select areas of the lower yard and shipped off site for recycling, treatment and/or disposal. The Unocal Edmonds Terminal is approximately 47 acres: the upper yard is approximately 25 acres and the lower yard approximately 22 acres. Petroleum -contaminated soil will be removed from an estimated 115,000 square feet of the upper yard; estimated soil volume is 15,000 cubic yards and estimated excavation depths range from 2 to 5 feet below ground surface. Metals - contaminated surface soil will be removed from an estimated 75,000 square feet of the upper and lower yard; estimated soil volume is 1,400 cubic yards; average excavation depth is 0.5 feet. Petroleum -contaminated soil will be removed from an estimated 40,500 square feet of the lower yard; estimated soil volume is 11,500 cubic yards; estimated excavation depth is 7.5 feet below ground surface. It is anticipated that approximately half this soil volume (5,750 cubic yards) will be returned to the lower yard excavations. Prior to backfilling, excavations in, the lower yard will remain open for approximately 1. month to allow for removal of fredfloating petroleum product. Product collecting in the excavations will be recovered by skimming and transferred into a temporary tank for subsequent shipment off site. Groundwater removed from the excavations during skimming will be transferred to a temporary tank. After testing for'suitability, the groundwater will be discharge to an on -site oil/water separator. Volume of product/groundwater to be removed from the lower yard excavations is estimated at 2,000 gallons. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist.

Supervisor Union Oil Company of California Post Office Box .76 Seattle, Washington Dear Mr. Barone: April 6, 1973 CxTP T FILE On !'arch; 16, H;73, our Mr. Ken Kukuk made a cross connection control inspection of the Union Oil Company and dockside facilities. During this inspection, three problem areas were noted and Vie recommended corrections are as follows: 1. Dockside watering point: To meet the.regualtions on cross connection control, an approved double check valve assembly will be required on the 4" service line supplyin'o the dock- side facility. To protect potable water supply to the ship I would suggest an approved double check valve assembly at each water outlet on the dock. 2. Laboratory: Properly install vacuum breakers on all water lines to laboratory benches .and slop sinks, or iRs,tall a re- duced pressure backflovi device OR D) on the rain ling: ser- vicing the laboratory area. 3. Flain Service Lines: Uue to the fact thLL re is an auxiliary high pressure fire fighting pump connected directly to the service lines that farnisi) v-ater to the onion Oil Cor'Pany, and the numerous possible cross connections on the grounds of the plant; there shall be an approved RPBU installed on the Admiral '.day service line prior to the teeing of tue water line to the dock facilities and the plant. There shall also be an approved RPBD installed on the line whicti serves the water tanks located at the pump hcuse on top of the Union Oil hill.' Attached please find excerpts from the "Accepted Procedure and Practice in Cross Connection Control Manual", which will give you the proper installation procedure.. Also attached is a list of approved reduced pressure backflow devices and double check valve assemblies -accepted by the State of Washington. - continued - r Letter to Mr. Andy Barone April 6, 1973 Page Two Mr. Y.ukuk will be making a final inspection in July, 1973, which we feel gives you sufficient time to make the necessary plumbing connections. If there are any questions concerning these corrections, please contact the Public Works Department, 775-2525, extension 225. Sincerely, CITY OF EDMONDS J.

FUJIKI AND ASSOCIATES Memorandum July 25, 1984 Subject: City of Edmonds Union Oil Company Watermain Loop project Plan Review meeting held July 24, 1984 at offices of Fujiki and Associates ` From: Michael L O'Neil To: Ken Fujiki Jim Adams, City of Edmonds Harry Chenoweth ~� Persons in attendance at the meeting were as follows: Jim Adams 1�� Ken Fujiki ���� Harry.Chenoweth Michael O'Neil Jim Adams delivered reviewed specifications for the project which were then discussed along with the plans. Items discussed were as follows: 1) The project will not require a 2% restoration guarantee or all risk builders risk insurance. 2) Sample insurance, city agreement, bid bond, performance bond, and railroad insurance forms shall be provided by the city via Jim Roberts (771-3202) 3) Statement in specifications shall provide that there shall be no charge for city issued permits. 4) Asphalt patching by the contractor shall be made of the trench backfilled with pit run, 4 inches of crushed gravel, and completed with a 2 inch lift of cold mix. The city shall later construct a permanent patch themselves. 5) Instead of attaching the pipe along the ground to the bridge piers it was agreed that thrust blocking may be used below the pips'; This alternate was suggested because of the distance the pipe would lay from the piers. 6) City shall make all contacts with the railroad for review of the design and the obtaining of permits. 7) A ductile iron alternative shall be includedin the contract and Fujiki and Associates will be paid above the.present contract amount for providing this service. ` 8) Fujiki and Associates are to provide one setof reproducible plans and specifications. ' � 9) Fujiki and Associates has performed the work contracted Or within the time constraints provided, but with the additions requested to the specifications and the adding of the alternative ductile iron design work will continue beyond the time period provided. 10) A fire hydrant assembly will be provide in lieu of the blowoff at the southwest corner of the Union Oil site. 11) Fujiki and Associates shall review,the city's comments in the specifications and add those items that are not presently included. 12) It was noted that the city's analysis of construction costs was about $10,000 less then that made by Fujiki and Associates. Fujiki and Associates felt that for budgeting purposes the higher estimate should be used. / By . Michael L O'Neil Civil Engineer 2 ` r 0 S y/S FUJIKI & ASSOCIATES, INC.

City Engineer City of Edmonds 200 Dayton Street Edmonds, WA 98020 Re: Union Oil Co. "Water Main Loop Project" Dear Jim: RECEIVED r,1�1. 2 71984 ENGINEERING S1���T FIIE Find enclosed a memorandum Mike wrote of the meeting in our office on July 25, 1984. If you have any comments or changes on the con- tents, please notify us. We have made a description of tasks and costs which will be involved to present the ductile iron alternative and insulation of the pipe line. 1. Investigate the best insulation system and protection for the insulation. 2. Write specification for the above. I. Make necessary revisions in drawings, including new supports. We need to investigate hanging the D.I. pipe at each end of the trestle in the same manner as the composite pipe. It is diffi- cult to say how extensive the revisions will be. 4. Add fire hydrant to drawing. 5. Insulation of the ductile iron pipe on the steep bank; we will need to support the pipes away from the concrete sills which is different from the present details. 6. We have estimated 16 hours of the Design Engineer's and 25 hours of the draftsman's time. The budget which will be in addition to the present contract is estimated as follows: Engineer 16 hours x 45.00 = $ 720.00 Draftsman 25 hours x 29.00 = 725.00 Total $1,445.00 9 James E. Adams, P.E. Page 2 July 26, 1984 Jim, we felt that the alternative may cost the above extra amount, however, we feel that in the final bidding process the monies will come back to the City. We are proceeding with the ductile iron alternative and will continue unless informed from your office to do otherwise. If you need my clarification of the above, please call me. Very truly ours, jeseeth Fujiki, P E. ident KF/ms Enclosure February 13, 1985 MEMO TO: Larry S. Naughten Mayor VIA: Peter Hahn Community Services Director FROM: James E. Adams City Engineer SUBJECT: PROPOSED L.I.D. TO CONSTRUCT UNION OIL WATER LOOP Per your instruction, I am not mailing the preliminary L.I.D. hearing notices to the Port and Union Oil. Since it is now our intent to fund this project through voluntary funding participation by the Port and Union Oil, it will be necessary to pass another resolution canceling the L.I.D. Resolution of Intent. I discussed this with Scott Snyder, and he is preparing the required documents. This item should be brought to the attention of the City Council at their next meeting.

CONSENT AGENDA MOTION: COUNCILMEMBER JAECH MOVED, SECONDED BY COUNCILMEMBER HALL, TO APPROVE THE CONSENT AGENDA. MOTION CARRIED WITH A UNANIMOUS VOTE. The approved items on the Consent Agenda included the following: (A) Roll call. (B) Passage of Resolution 587 to allow city departments and officials to process and approve applications for subdivisions and short subdivisions in the Meadowdale area of Edmonds. (C) Final acceptance of work by David Edwards Construction for Dayton St. improvements. (D) Set date of April 24, 1984 to discuss parking alternatives on Elm St., 7th Ave. S. to 8th Ave. S.

(G) Report on bids opened April 4, 1984 for 1983 Street Overlay Projects and award to Seattle Services Co. in the amount of $62,088.75. MEET WITH PETITIONERS FOR PROPOSED ANNEXATION OF AREA NORTH OF 220th ST. S.W., SOUTH OF 217TH ST. S.W., AND WEST OF 92ND AVE. W. Assistant Planner Duane Bowman reviewed the petition.requesting annexation into the corporate limits of Edmonds. He noted that the petition had been submitted in 1983 but the City had requested petitioners. to seek a more reasonable and logical area for annexation which they have done. The City has established the zoning for this area as RS-8 (single family residential) upon annexation. The questions before the Council this evening are whether to accept the proposed annexation and whether or not assump- tion of indebtedness will be required. He observed that the annexation does not appear to pose any significant service problem for either utilities or streets. The staff recommends annexation of the area and assumption of the indebtedness of the City of Edmonds by the annexed area. Mr. Bowman displayed an overhead transparency showing the location of the proposed area for annexation. He added that another area of unincorporated Snohomish County lying.east of 92nd Ave on 220th St. S.W. may be brought before the Council on a 75% annexation petition in the near future. July 23, 1984 MEMO TO: Larry S. Naughten Mayor FROM: James E. Adams �/L City Engineer SUBJECT: UNION OIL WATER LOOP LID On April 17, 1984, the City Council passed Resolution of Intention No. 263, which created a Local Improvement District to construct the Union Oil Water Loop. Section 4 of the resolution sets September 4, 1984 as the hearing date for the preliminary assess- ment roll. R.C.W. 35.43.150 requires that the beneficiaries of the LID be notified at least fifteen days before the scheduled hearing. The Council has asked that this notice be at least thirty days prior to the hearing. The notice must include the preliminary assessment, which is our best estimate of the final assessment for each benefited property. Since time is getting short, to meet the September 4, 1984 deadline, I am beginning to prepare the preliminary assessment roll, with the total cost distributed evenly between the Port of Edmonds and Union Oil. To date, we do not have easements across either of the properties Unless directed otherwise, I will include the following charges in the assessment: 1) Design costs - 2) Construction costs — 3) Engineering staff time Memo to:' Larry S. Naughten July 23, 1984 Page 2 4) Legal fees 5) Normal administrative costs (financing, etc.) 6) Estimated fees for acquisition of easements — I recommend that we speak with the Council, in executive session, prior to mailing the preliminary assessment notices. JEA/st AUTHORIZATION TO SOLICIT BIDS FOR RENOVATION OF WADE JAMES THEATER [Item E on ConsentAgenda] Councilmember Jaech asked if the funds for this project were budgeted. City Engineer Jim Adams replied that HUD block grant funds were being used.

AUTHORIZATION TO ADVERTISE FOR PURCHASE OF LADDER TRUCK 26 000 tem H on Consent Agenda In response to a question from Councilmember Jaech, Acting Public Works Superintend- ent ,Bobby Mills explained that funds for replacement of vehicles have been set aside. Currently there is $16,000 budgeted in 1984 and $11,000 in the B Fund for purchase of this vehicle. Mr. Mills responded to questions from Councilmember Kasper and Wilson explaining that the present vehicle was purchased used in 1964 and has been used only for emergency purposes to prolong its useful life. A new truck would be used for various activities in addition to changing of traffic signal lights, such as last year's repair of the grandstand, trimming tree limbs in the City parks, installation of banners for special events, etc._ He said the only other truck of this type is owned by Snohomish County. Mr. Mills said he had investigated the possibility of obtaining a used truck but the only ones available cost close to $20,000. He added that the present truck would be traded in or sold upon purchase of a new truck.

LOOP - WATERLINE RE: LICENSE AND EASEMENT FOR WATERLINES This is to confirm our conversation with you in regard to changes negotiated between Patrick 0. Wilson of the Engineering Department and Mr. Neil Theriault of Union Oil Company, per telephone call on September 4, 1984. A. In regard to Easement No. 4 on page 2 of EXHIBIT "A", we are changing the revised call, N 88°51'46"W, back to our original call of S89°47'45"W. The reasons for this are: 1. All subsequent calls and their associated deflection angles depend on this first call as specified in order to tie into a document, now recorded under Auditor's File No. 7911190250. This document is also referred to, in this present "Easement for Waterlines," on page 3, paragraph 7. No map was filed with that instrument and the description governs. 2. The original first call refers also to a certain bound, namely, "The South line of'said Government Lot 1." This line is a known monumented;line. Washington surveying regulations permit the use of relative bearings, where the set of calls remain self -consistent. 3. There are, in fact, on this entire project, three different relative bearing sets. All were converted (or rotated) to a common set for overall check of closure on certain lines and monuments. The validity of each portion was thus proved. Thereafter, every attempt has been made to retain old, valid descriptions as already recorded, in.their original form, together with reference to a common bound as a tie. New descriptions only were specifically based on the bearing system shown on the map of the Union Oil Company property, which we submitted for graphic information purposes. This map was intended to coincide with such new descriptions, while we recognize that there exists many other surveys describing the same points but on a different bearing system which are equally valid and which, when rotated properly, will close. 4 Jim Jessel September 7, 1984 Page 2 4. A change of the first call would require a change in all subsequent calls in Easement No. 4, in order to be self -consistent and to close reasonably. The revision of the one call, made by Union Oil Co., prevents the easement from closing, and it is simpler to change the one call back to the original and to have the proper reference to its parent document, as cited above. We have made this change. B. In regard to Easement No. 5B on page 3 of EXHIBIT "A", the 5-foot wide easement is, in fact, on the northeasterly side of the ekisting fence line, which bears S47°37'26"E from the Burlington Northern right-of-way lines. Therefore, we have made this change back to our original call. C. Subsequent action required: 1. Have Mayor Larry Naughten initial the marked changes on each of three ( 3 ) copies. 2. Return the initialed copies to Robert F. Woehrmann, together with a copy of this memo, for the necessary counter initials. 3. Request Union Oil Company to return the copies to us for recording. 4. Record and send copies of the recorded instruments to Union Oil Company. 5. Proceed with obtaining the necessary consent from Burlington Northern Railway on the attached license, per paragraph 2, page 2, of said license. Also, obtain the additional easement from Burlington Northern as indicated by the waterline construction plans.

Adams City Engineer SUBJECT: UNION OIL WATER LOOP CONSTRUCTION FILE On April 17, 1984 the City Council passed Resolution of Intention No. 263, establishing a local improvement district (L.I.D.). The project is the construction of a waterline loop from the top of Union Oil Hill to Mariner Park. This water loop will benefit.the Port of Edmonds and Union Oil by.decreasing.the probability of interruption of service, and it will increase the volume of water available in the event of a fire. The current status is: 1. The plans and specifications are completed. 2. We have the required easement through the Union Oil property. 3. We are negotiating with Burlington Northern for an easement across their railroad tracks. 4. We need a dedication and an easement from the Port of Edmonds of the present line through the southern portion of the Port. Without the pipe through the Port, this proposed construction will be of no value. The Port Commissioner contends that there was a verbal agreement a few years ago where they would dedicate the present pipe and award an easement to the City as their contribution to the water loop. Our records tend to agree with this premise. The City Attorney advised us that we may not be able to acquire the present pipe nor an easement from the Port by condemnation. The City Council's policy is that we mail notices thirty (30) days prior to scheduled hearings. To meet the current scheduled hearing date, we must mail the notices by October 6, 1984. Since we have not acquired the necessary easements and there may be additional attorney fees for this action, it is difficult to estimate the total expenses for the L.I.D. William Kasper September 24, 1984 Page 2 In the past, City Council members have expressed concern when property acquisition costs have caused substantial increases over the preliminary assessment, and they have recommended that we not proceed with L.I.D.'s until we acquire all the necessary property. Due to weather, we cannot begin construction until March or April, 1985. Since we have an undetermined cost for easement acquisi- tion, unknown attorney fees, and with Mr. Maxwell of the Port being on vacation for the next month, I recommend that we postpone the L.I.D. hearing until March, 1985, in order to continue negotiations.

JEA/st va� 1 ¢w CITY OF EDMONDS CIVIC CENTER • EDMONDS. WASHINGTON 98020 • (206) 775-2525 OFFICE OF THE MAYOR Fort of Edmonds Edmonds, WA 98020 Dear Commissioners: LARRY S. NAUGHTEN MAYOR January 3, 1985 STRE"zcg FILE I am writing to you in order to update you on the status of the water loop construction project. The City of Edmonds is making definite plans to proceed with the project by Spring of 1985. It is our position that the benefits of this project justify proceeding with construction as soon as possible. It is the prefehance of the City to work cooperatively with the Fort of Edmonds and with Union Oil, and to divide the costs evenly. It is estimated that the total project cost will be $60,000 and that each of the three participants will therefore contribute $20,000. Preliminary verbal indications from Union Oil have been positive, although the final decision has yet to be made at the corporate headquarters. A written response from Union Oil is forthcoming. In April 1984 the Edmonds City Council adopted a resolution of intent to form an L.I.D. (local improvement district) for the purposes of funding this project. This legal process would require that we proceed with the next step by the beginning of February. The unfortunate byproduct of an LID process is that costs will escalate substantially, and will be passed on to all three parties. These additional costs - both legal and engineering - could bring the total project cost to over $100,000. It seems to me that it would greatly benefit all of us to simply agree to share the costs as outlined above, thereby avoiding the more costly and cumbersome LID process. I hope that you share my view and that we can choose the alternative which reduces our costs and simplifies the whole project. The City is hoping to receive a response from the Port and from Union Oil before the end of January. Otherwise we would have to proceed with the LID schedule as set out by State and local laws. 1 • • Thank you, and a Happy New Year Larry S. Naughten CC.

This information is being submitted to the City of Edmonds for approval. The system is designed for a capacity which includes the waste from 2 restrooms in your proposed office building. We understand that there will be 2 toilets, 2 washbasins, 1 urinal and a utility sink. We also understand that there will be 7 full-time (one shift) employees at the office. In addition, there will.be about 24 drivers who may use the facility part-time. Waste capacities have been computed utilizing the. above figures. The U.S.Manual of Septic Tank Practice allows for 15 gallons per day per office worker. We have used ­a rate of 50% of this figure for the drivers. Therefore, we have computed the tank size and absorption areas required as follows: 7 employees @ 15 gallons equals 105 gallons per day. 24 part-time @ 7..5 gallons equals 180 gallons per day. Total gallons per day equals 285 gallons. Allowing 1.5 gallons per day absorption per square foot, at our percolation rate of 10.6 285 gallons 190 sq.ft. absorption area 1.5 1.5 ft. trench width 127 feet of 18" wide trench. The City will review this information and may adjust tank size and/or required absorption area. CIVIL ENGINEERS / LAND SURVEYORS • BUOROED & HITCHINGS, INC.

A fire or explosion will not acmur If one of fbe three elements is. missing. This Rlndaauntal principle is ex- tremely important for the prevention of fines and mplco- lions during work In and around tanks. Wbem flammable liquid fuels exist. flammable vapors will also exist. To make it safe to work In tanks, both the hydrocarbon liquid and Its vapor should tie removed from the tank, as der. scribed in 4.4 and 4.7. After trey have been removed, the etmosphccz 111.0c tmfk should be tested for vapor coneen. tration as described in Section 5.

Unlikc vapors and gases, ignition sources cannot be prac- tically detected by an insawwnt. The vapors of most pe- troleum finis, such as gasoline, are heavier than air and settle In low places. They can spill from a tank and can now like water. '[hey can travel considerable distemcca, encounter a remote ignition source, for example, a car or truck engine, and be ignited. They can flash tack to and into the tank where they originated and cause an explo- sion. For safe tank work, it is desirable to eliminate two of the three elements required for a fire, namely, fuel vapor and ignition sources. The elimination of oxygen by inettirg is another M&hM of preventing fires but is not normally used for tank clean- ing. The elimination of oxygen is difficult and costly and introduces aftother hazard. an oxygen-deftcwnt atmortphgle for workers. Oxygen deficiency is described in 3.3. Mixtures of hydrocarbon vapor and air can be ignited only if the fuel -too it ratio is within certain limits. For cacti hydrocarbon, there is a minimum concentration of vapor in air below which a fire or explosion will not occur an contact with a source of ignition. Thcrc is also a maxi- mum concentration of vapor in air above which a fire or explosion will not occur. The boundary -line mixtures of vapor or gas in Air that will, if ignited, just propagate flame are known a3 the lower flammable limit (LFL) and the upper flammable limit (1TFL), respectively. They are usually expfrsaed as percents by volume of vapor or gas in air. Different gases and vapats have different flammable ranges. The flammable ranges of some common gases and vapors that may be present in and around tanks during entry, cleaning, and repair are shown in Table 1. Informa- tion_on the flammable ranges of other hydrocarbons is given in NFPA 325M. Figure 2 shows the flammable range for gasoline vapor in air. Tank fires and explosions have occurred when workers were in a tank in which the gasoline vapor/air mixture was thought to be in the rich range. It was mibtak- enly believed that a rue could not occur under such condi- dons. The extreme danger of d* belief is that a rich atmosphere will ultimately dilute with air until the mixhm Table 1—Fuels and Their Flammable Ranges Flammable Range Fuel (voltmw pamo.a) Hydrogen 4 to 75 Hyd-aen sulfide 4 to 45 Metn3ne .51013 Pevpner 2t0 9 Butane 210 e Gasoline Ito 7 Kerosene t to 3 Low. -or upper flammable flammable limit limit t l- ey Ftaromabl Rich t 7 rev, tots Sox loose, Figure 2-Flammable Range for Gasoline Vapor in Air is within the flammable range. This dilution may occur at tank openings such as hptchc3, manways, or vents. Section 6 describes the cooditions under which workers may enter at tank safely, if they follow proscribed requirements. The importance of removing all recoverable hydrocar- bon liquids and their vapors cannot be ovenemphssiud. Even After a tank has been freed of vapor, flammable mix. lures may be formed attesh from any remaining residual liquid and sludge or by the inadvertent entry of a liquid or: vapor firm otolde. Petroleum vapor or liquid may enter a tank through unblinded lines or fram leaks in the bottom of the tank. Vapor way evolve within a supposedly empty and clean tank frnm flamotables mnaining in sources and places that were overlooked. The most common sources or places are sludge, scale, hollow roof suppsrts, unsealed sections of foam ehernbers, pontoons, heating coils, lea king bot- tom&, and internal wooden awxturcs or other absorbent material. Heat front am sun, steam tracing, and hot work may increase the ferric vapor concentration. The tank at- mosphere Should be frequently checked for the presence ut vapor even though initial McMuTements indicate that the cuncemration Is within acceptable limits (fur acceptable limits, see Section 6). Flammable vapor/air mixtures may be ignited by many lgnitlon sources, such as open flafues; gasoline or diesel engines, lightning, smoking, electrical shorts in worn or defective extension cexxs, and sparks. Spark sources in- clude electric lamps, Rower tools, fixtures, switches, aonexplosionproef appliances, welding, and static electric, ity. AN Publication 2214 does not roquirc the use of non- ferrous hand tools to avoid a sourcc of ignition. Another source of ignition may he present in tanks that have been used for the storage of sour stocks, aromatic tars, or as- phalt. The sulfur compounds in Sour stock can react with the iron of storage taroks 10 form f-ux:ly divided deposits of iron polysulfidc, which arc pytophorie on exposure to air. When these pyrophoric deposits corm in contact with air, . a heat-gcaerating dtemicat reaction takes plsire. If the heat is not dissipated, spot temperatures high enough to ignite a flammable mixture or residue can be mashed (sce 4.8).

Oxygen deficiency in a petroleum storage tank that has not been suffrcisntly ventilated can be a major- threat to the workers inside the tank. Most hydtocarWa vapor$ are heavier than air. They may dkAaoc dte air In the tank and make the acmoephorc oxygen deficient. The atmosphere in the tank may become stmdfled, with the bottom portion of the tank cascatially Vold of oxygen, the middle portion containing some oxygen. and the upper, portion in the flamtaable range. A person entering an oxygen -deficient tank may be subjected to two potential bazards, fire and asphyxladM and possibly to a third, toxic substances, Persons working in tip oxygen -deficient atmosphere without appropriate respiratory equipmeat usually do not notice that the atmosphere is oxygen -dentinal. There is little or no wttming, and the effects are comoomding. be- ginning with the loss of reasoning ability and followed by unconsciousness. Death or brain damage can occur within minutes if the body is deprived of oxygen. Air within a tank that has been closed and otrt of ser- vice may become oxygen-detieleat as a rmh of the lust- ing of metal. Oxygen deficiency eta also w= when inOn tests Men nitrogen are used or when inert welding Eases are used.

The atmosphere in all tanks that have contained sour stocks should be considered toxic, and spc- cial precautions art necessary for safe tank entry, Fortu- nately, hydrogen sulfide is gradually eliminated by refining processes and is virtually absent from moat finished prod- ucts- In low concentration, it is detectable by its character- istic odor; however, the sense of smell cannot be relied on, to warn of dangerous concemrtltions because instantaneous exposure to higher concentrations of the gas immediately paralysis the seine of Smell. Exposure to lower conceAtrs- tions for A *hart period has a similar desensitizing d%ct.

CML) Of tnhamothyl lead CMI L,) or mixtures of the two, are toxic. When added to gasoline, the Iced alkyl creates a potential. argauic lead hazard in ranks that stare leaded gasoline. Every storage tank that has stored leaded -gasoline must be rzgatded as having an additional hazard, toxic organic lead. Tills hazard can exist in firm a that were formerly used to store leaded gasoline but, without cleaning, were Inter switched to storage of a nonleaded product. It is mrmduaory that the precautions and procedures described in Sccd(m 11 be followed when entering leaded-Saadinc storage tanb. Alftugh the quantity of leaded gasoline being produced is diminishing because of federal ma xWes. the vast num- ber of tanks that pr+pcnt an organic lead hazard will prob- ably continue to exist for some time because, in most cases, Wks were not cleaned and declared lead -hazard -free prior to the *witch fmm the storage of leaded gasoline to the stmW of nonleaded gasoline.

For example, benzene is hazardous at very low concettuldous (arc 3,4,6). Appropriate personal protective equipment should be worn accor&g to the recommendations of Sec. tions d and 7. The inhalation of high concentrations of hydrocarbon vapor can cause symptoms of intoxication. These symp- toms range from disxiness to excitement to unconscious- ness; they are sim bet to those produced by alcohol or anesthetic gases. It such effects occur, the indivi" should be removed to fresh air. If the exposure is minor, fresh air or sniffing.oxygen may result in rapid teoovay. If bmath- ing has stoppod. artificial respiration should be started promptly. Inhalation of liquid hydrocarbon Splashes or droplets may cause unconsctousaess or death, Medical at- tcndon should be obtained immediately. lNposure to pctroleeun substmtces should be minimized.

The compositlon and quamlty of fames depends on the materials being welded. the compo- sidow of the rods and of any coating's, or paints affeetrdt the process betng used, and the circumstances of use. Toxic fumes am generated duttM the welding of ntctala coated with or containing alloys of laid, zinc, cadmium, boryl- Rum. and certain outer metals. some paints may product toxic fumes when they arc heated with the welding torch. The potential health effects of welding fumes range in type and seventy depending on these factors; some effects can be extremely serious.

This prevents hydrocarbon vapors or Uquids from entering the tank through the lines. Blinding off is Wxomplished'by first closing all of the valves nearest the tank, breakdna the connections. and placing blinds in all of the lines. Blinds should .be strong enau>Cb and thick enough to withstand the maximum pressure that might be exerted against theta. Before the blinds are installed, all lines betwmn rim tank and the location of the blind should be drained or flushed. Fount chambers on the tank should be opened and in- spected to ensure that the scats ate intact and that product is not trapped in an area open to the tank. Drains at the base of pipe risers. to the foam chambers should be left Open. Heating coils should be diaconneCuA or blhtded. Electrical connections to mixers and other electrical equipment inside the tank should be disconnected and togged or locked out (see OSHA 29 Co4 of Federal Regulations 1910.147). if tie tank bottom is protected from oormsion oxOtrna11Y by an impressed-mmat ayatem, a bond wire should be used when discnntrecting Pipe flanges. All tank ground cables and cnbk damps should be inal octcd to ensure groundingand bonding integrity. -6 Working on the Tank Roof and Near the Tank During Vapor -Freeing CAMON; The atmosphere within a tank that has been emptied [nay be in the flammable range. Work on the roof and adjacent to the tank should be limited to what is essential. Workers should not be permitted to wa(l. on iattxrhal floating refs during vapor freeing (see Section 10). . Whim it is necessary for work4U to walls on a tank roof. an �napecaon should be Made to determine what safety measures are needed. Planks should be used to distribute the workers' weight if the roof is in questionablc condi- Lion. Safety belts and lifelines can be used, with a desig- nated rescue worker standing by in case of an accident. Wben work is being performed on the outside of [aoLq that have contained sour stocks. workers should wear air - supplied respiratory equipment in locations where expo- sure.may occur. 4.7 Vapor -Freeing the Tank After the tank has been emptied of residual product blinded off, and eleotrically isolated, it should be freed of hazardoux vapor. In the initial stage of vapor•heeing, while the tank still contains high conceotratians of flammable vapor, th4utcnanco work in the area around dlc tank and on the tank roof should be -kept to a minimum. During the vapor -freeing paces, the time during which the vaporlair mixture ltt the tank is hi the flammablc range should be OdniMIX4. Also, the vapor coming frohn the tank should be prcvenled from producing hazardous con_ ditioas outside the tank. Since most hydrocarbon vapors arc heavier than air. one way to reduce the possibility of vapor producing hazardous conditions outside the tank is to discharge the vapor at the top of the teak or at a high elevation. This allows for maximum dissipation of vapor and seduces the potential of flammable vapor reaching an Ignition source and of human exposure. The selection of an effective Vapor freeing method de- pends on many factors: the type of product stored in the tank, such as viscous crudes, gasoline, or liquefied gases; the We of tank design, such m a cone -roof, tank, an exter- nal or internal floating -roof tank, or a pretgure storage tank; the tank location. such as below ground level; and the site of the tank. 'There are several methods for vapor - freeing a tank: mechanical ventilation, tacatn ventilation, natural ventilation. and vapor disPla cement by flooding with water (see 12.7). 4.7.1 MECHANICAL. VO(Y LATION 4.T.1.1 General Altcbanical ventilation is normally the preferred method if the task's design and location and the product in the tsnk permit it. An irnpom mt feature of this method is that it can, depending on where and Crow the sir movor is in- sta W, discharge vapor at a high elevation, for example, near the roof line. Mechanical ventilation equipment nor- mnlly consists of an eductor or blower (air mover) driven by an edoaric motor. air, ar steam. The equipment must be suitabic for hazardous locations and the air mover must be electrically bonded to the tank (see 4.3.3). if it is driven c"leally, the requirements of 4.3.2 [must be abet. If it is driven by Stearn, the steam exhate%t should not enter the tank unless the ptrcautions of 4.7.2 arc observed. 4.7.12 Mechanically Vapor -Freeing Gone4loofTank3 There are several atmthods for mechanically vapor- free-ing a come -roof tank, such as the following: a. Install an air mover on a roof manway.. Vapor is dis- charged at the roof roanway as fresh air enters the tank through a bottom shell manwtty. With the bottom shell manway closed, the air [mover should tie starred at a low delivery rate to create it slight negative pressure inside the tank before the bottom shell manway is opered_ This cs- SENT BY: 6- 2-33 ; 16:42 ;EMCON Northwesi,lnc. 2067710221;#18 El L7, l 81 SArE.

After the shell manway cover has been �ernovod, the air mover may be operated at hell capacity. Any other bottom shell manways may now be opened if the air mover is song enough 10 cause fresh air to enter all of the open manways (vapor should not be allowed to escape through bottom shell manwaye). b. on one of the roof manways, install an air mover with a flexible tube attached to it that catends to near the tank bottom.

Place an air mover on the bottom shell ntanway and force air into the tank. allowing the v,podeir mixture to esc" trough the roof amemy. The roof martway should be kept closed until after the blower is installed in the shell manway. This minimizes the escape of vapor at the shell manway. The roof manway is then opened, and the blower Is started immediately. 4.7.1.3 Medwrtkafky Vapatrteelng opert.Top RoWng-Roof Teurka Tate methods for ,oeltaritally vapor -freeing open -top floating -roof tanks are as follows: a. The space above the floating roof may be mecbmi- cally ventilated by installing an air mover at the top of the tank and connecting it to a duct that is lowered near the floating roof. This duct allows the vapor to be discharged at the top of the shell perimeter. To vapor -file the space below the fi0attng roof, an air mover is installed on a.shell manway. The air mover is positioned on the manway so that It draws air thrcwgh the tack, It ,hould preferably discharge Into ten ell and a vertical duct to expel the vapor at as high a level as possible.

To ventilate undo the root, air Is drawn in through the open piping attachment norrdcs and through the floating roof's annular seal area. Routing roofs am usually cquippzd with a vent that OMI when the roof is positioned nn its legs. Air can be drawn In through this vent to provide additional venti- lation. 4.7.1A Medlattically Vapgrr.Freqlng Coveted FWntin~ Tanks Thu methods for mechanically vaw-freeing covered floating -roof tanks. arc as follows: a.

This avoids tht building of excessive pressure while steaming and the creation of a vacuum while cooling. If steam vapor -freeing is used, sufficient vacuum venting roust be provided to prevent vacuum formation within the ves- sel as a result of rapid steam condeam ion. Steam vapor -freeing may be Appropriate for small tanks having an initial vapor/air atmosphere that is known to be vapor -rich (above the upper tlurmmable limit). By injecting Purge steam through art eWosed piping connection, the tank atmosphere is displaced by steam and never goes through the flammable range, For this nteJKW to be effec- tive in removing all vapor. the steam rate Must be high enough to produce a good steam plume from the roof manway, whlCh should ideally be located opposite the Steam inlet to ensure a eothplete purge of the tteuk'a in, rior. 4.Y.3 NATURAL VEPI'y1LAMN Natural ventilation should be avoided if other methods are available because vapor tray drift to a source of igni- tion. Natural ventilation simply entails mmoving: the roof and shell manway covers and allowing the tank to stand idle until natural ventilation makes the tank vapor -free. It is a slow process. At least at the start the dense vapor will flow frOM tlta shell manway. As the vmtitation progreew. the flow of vapor may reverse and flow frmn the, toot manway because of changes in the density of the vapor and in wind velocity.

When the vapor concmitration has been reduced to 50 percent or less of the Iowa flammable limit and'air it entering file bottom shell mauways, personnel may begin cleaning air working outside the teak. To begin cleaning from the outside, a water -hose stream dittoed through open manways, rwatting nozzles pointing inward from the tank shell, and many similar devices have been used to dislodge sludge and float it to a wafer draw or pumpout connection.

The employer and the person directing the job it the tank site must be fully familiar with these hazards and . with the nuAtods of controlling theta, 4ag precautions and procedures such as those described in this publication. 3.2 Fires and Explosions A rue or explosion occurs when the proper proportions of petroleum Net vapor and air arc exposed to an ignition eourne. Thu three elements necessary for a fire or an ex- plosion arc fuel vapor, air (oxygen), and an ignition sourve. as shown in,thc fir; triangle lit Figure 1. A fire or explosion will not occur if one of the three elements is missing. This fundamental principle is ex- trcmcly important for the prevention of fires and eapio- ,dons during work in and &mad tanks. Where flammable liquid fuels exist., flammable vapors will also exist. To make it safe.to work In tanks, both the hydrocarbon liquid . and its vapor should be removed from the tame, as de- scanted in 4.4 and 43. After they have beers removed, the attmosph= in the tank should,be tested for vapor eoncen.' tration as described in Sejction 5. The elimination of hy- drocarbon liquid and vapor is am primary method for fire prevention during tank.wofIL Eliminating ignition sources, especially during the.va- pot-freeing process, is equally important, lbe elimination Figure i-The Fire Triangle SENT BY: 6- 2-93 ; 16:31 ;EKON Northwest, Inc. 2067710221411 API PUMUCATICX4 2015 of ignition sources can be more difficult and legs certain because ignition sources may be unrecognizable or remote. Unlikc vapors and gases, ignition sources cannot be pTaa tically detected by an insmunent. The vapors of most pc- rroleum fuels, such as ga"ine, are heavier than air and settle in low places. They can spill from a tank and can flow like water. They can travel considerable distuucca, encounter a remote ignition source, for example, a car or truck engine, and be ignited. They can IIash track to and into' the tank where they originated and cause an explo- &ion. For safe tank work, it is desirable to eliminate two of the three elemena required far a lire, namely, fuel vapor and ignition sources. The elimination of oxygen by i4artirg is another meth of preventing fires but is not normally Used for tank clean- ing• The elimination of oxygen is di;ffrcuit and costly arid' introduces another hazard. an oxygen -deficient atmosphere for workers. Oxygen deficiency is described in 33. Mixtures of hydrocarbon vapor and air can be ignited only if the fuel-m-air ratio is- within cet'tain limits. For each hydrocarbon, there itt a minimum concentration of vapor in air below which a foe or explosion will not occur, on contact with a source of ignition. Thor, is also a amil- mum concentration of vapor in air above which a fire or explosion will not occur, The boundary -line mixtures of vapor or gas in. air that will; if ignited, ,just propagate flame arc known as the lower flammable limit (LFL) and the upper flammable limit (UFL). respectively. They are usually expressed as percents by volume of vapor or gas in air. Diffcrcnt gases and vapors have different flammable: ranges. The flammable ranges of acme common gases and vapors that may be -present in and a build tanks during entry, cleaning, and repair am shown in Table 1. Informa- tion on the flammable ranges of other hydrocarbons is given in NFPA 3:25M, Figure 2 shows the flammable range for gasoline vapor in air. Tank firer and explosions have occurred when workers were in a tank in which the gasoline vapor/air mixture was thought to'be in the rich range. It was mistak- enly believed that a fire could not occur under such condi- tions: The extreme danger of this belief Is that a rich atmosphere will ultimately dilute with air until the mixture Table i—Fuels and Their Flammable Ranges Flammable hangs Fuel (volume P'Wwra) Hydrogen 4 to 75 Hydrogen WE& 4 to 45 Methane 51015 a"ol'an. z to 9 Butane 2 to g Gasoline I to ) Kerosene Ito 3 Lower upper narnmable flammable Iienil limit t. a Flaramabi Rich A 7 :i I 10% 26% 90% 100% Figure 2-Flammable: Range for Gasoline Vapor in Air is within the flammable range. This dilution may occur at tank openings such as hatches, manways, or vents. Section 6 describes the conditions under which workers may enter a tank safely, if they follmx prescribed requirements. The importance of removing all recoverable hydrocar- bon liquids and their vapors cannot be overemphasized. Even after a tank has been freed of vigor, flammable mix- tures may be formed altesh from any remaining residual liquid and sludge or by the inadvenent entry of a liquid or vapor from outside. Petroleum vapor or liquid may enter a tank through unblinded lines or from leaks in the bottom of the* tank. Vapor tray evolve within a supposedly bMpty and clean tank fr„m flama =bles reznailiins Ln sources and places Haut were overlooked. The most common sources or places are sludge, scale,hollow roof supports, unsealed sections of foam chambers, pontoons, hunting coils, leaking hot- tomst arid. internnl woods, awxtures or olhet absorbent' ,material. Heat from the man, steam tracing. and hot work may increase the tank vapor concentration. The tank at- trtospherc should be frequently checked for the presence of vapor even though initial measurements indicate that . tttc .cQn0CnrtaUon is within acceptable limits (fur acceptable limits, see Section 6). Flammable vapor/air mixtures may be ignited by many Ignition sources, such as open flanges, gasoline or diesel engines, lightning, smoking, electrical shorts in worn or defet:live extension cords, and sparks. Spark sources in- clude electric lamps, power tools, fixtures, switches, nonexplosionprucf appliances, welding, and static electric- ity. AN Publication 2214 does ndt require the use of non- ferrous hand tools to avoid a sc urcr- 'of ignition. Another source of ignition my he present in tanks that have beers used for the storage of sour stocks, aromatic tars. or as- phalt. The sulfur compourdm in sour stock can react with the iron of storage tanks to form rw,(ydivided deposits of iron polysulfide, which arc pyrophorie on exposure to air_ When these Pymphoric deposits comae in contact with air, A heat-gcncrating c3tcmicat rtaClion takes plane. If the heat is not dissipated, spot temperatures high enough to ignite a flammable mixture or residue can be reached (ace 4.8).

Most hydrocarbon vapor& Are heavier than air. They may displace the air In the tank and make the atmosphere oxygen deficient. The atmosphere in the tank may become stxatllled, with the bottom portion of the tank essentially void of oxygen, the [riddle portion containing some oxygelL and the upper portion in the flammable range. A peen entering au oxygen -,deficient tank may be subjected to two potendal hazards, fire and asphyxiation, and possibly to a third, toxic substances, Persons working in an oxygen -deficient atmosphere without appropriate respiratory equipment usually do not notice that the atmosphere is oxygen -deficient. There is little or no warning, and the effects are compounding. be- ginning with the loss of reasoning ability and followed by unconsciousness. Death or brain damage can occur within minutes if the body is deprived of oxygen. Air within a tank that has been closed and out of ser- vice may become oxygen-deticlent as a result of the rust- ing of metal. Oxygen deficimey can also occur when inert gases like 111trogen are used or when inert welding gases are used. The oxygen content of a tank atmosphere must be de- termined with an oxygen analyzer before anyone ontora the tank If the atmosphere contains lase than 19.5 percent oxygen, it is oxygen -deficient and appropriate roapiratary equipment must be worn. For tank -cleaning, if the oxygen content is less than 16 percent, the tank must not be en- tered. 3r4 Toxic SubManceS Toxic substances can cause injury, acute or delayed illness. or death, depetuling on the, characteriatica of the substances. their concentration, and dw duration of Cxpo- 5 sure.

They can affect the tissue at the point of contact tar organs re- mote front the pint of contact. Irritants are substances that cause minor or transient but poasibly painful injuries that heal without scan and pro. duce no known aftcrcffmu. Many hydrocarbons and polar solvents arcs irritants, Corrosives are subsuances that destiny tissue and leave permanent Scars. Example& of corrosives are hydrofluoric acid, sulfuric add, and caustics. Acutely toxic sutagistrtces are those'that by a atingle dose or short-term exposure cause symptoms ranging from a Simple headache or nausea to disablement or death. ifs drogen sulfide can be acutely toxic. Cbmaically, toxic substances am those that may pro.! duce physiological impairment with long latency, such as cancer, or with gradual ptvgmssWIL such as pulmonary; obstruction disease, or harmful effects on reproduction. PcmtWdbk exposure fbnit (PEL) and thresAald limit value (TLV)' are terms commonly used to describe the corcntration In air of an alrbome toxic substance to which,I it is believed, nearly all workers may be repeatedly ex- posed without adverse affects.

It is coloricsa and in low concentrations has a foul, rotten -egg odor. Since hydrogen sulfide is heavier thaw air, it tends to collect in low places. The annospliere in all tanks that have contained sour stocks'should be considered toxic, and spc- cial precautions are necessary for safe tank entry, Fortu- nately, hydrogen sulfide is gradually elirti rated by refitting processes and is virtually absent from most finished prod-. uets. In low concentration, it is detectable by its ehuaum- istic odm; however, the sense of smell cannot be relied on to wam of dangerous concentrations because imtentaneans exposure to higher conceat radon of the gee Urtrnadiately paralyzes the sense of $mall. Exposure to lower concentra- tions for it short perivd has a similar desensitizing act. The Occupational Safety and Health Ads iniceration (OSHA) has prescribed exposure limits for hydrogen aul- fide of 10 parts pet million tithe -weighted average (TWA) in an 8-hoar work shift and of 15 pane per million ahon- term exposure limit (STEM) averaged over 15 minutra. The concentration of hydrogen sulfide in an atmosph= can be measured with various hydrogen suffink i"ca- tors. The accuracy and resporm times of such indlewors vary. Users should undeotsnd these and other Ifttations of the instrument used. Exposure to high enough concentrations of hydrogen sulfide causes death by paralysis of the respiratory System,, - pad there is soma indication that the presence of alcohol in the blovd aggravates the olI' W of hydrogen sulfide in acute poisoning cases. In low doses, it is irritating to the eyes, and respiratory tract Repeated short exposures may lead to chronic irritation of the eyes, now, and throat; ,however, the effects of such expoeute are not cumulative, and the symptoms usually disappear soon after removal from the eaposttre, It should be understood that the waft of smell may be completely bloc6d by hydrogen sU1Mde; this can result in a worker failing to r®cogtllze the pres- ence of dangeroualy'high cone ntradom. Hydtogea sulfide is a flammable. gas that bums in air. Its flammable limits are 4 percent to 46 percent by volume in air, so precautions against sources of ignition must be obmvcd if it is present. A test fnt hydrogen sulfide should be made before'any work is started on ranks that may have contained products containing hydrogen. sulfide, such as sour stocks: the test should be repeated f wpendy. 8.4.g LEADED GASMNE Leaded gasoline is produced at.refu de3 and, to a very limited extent, at product terminals. This 13 accomplished by adding an organic lead compound, a lead aryl, to gasoline. The .purpose of the lead alkyl is to raise the octane of the gasoline. Lead alkyls, tetraethyl lead (TEL) or tatramethyl lead (rML) or mixtures of the two, are toxic. When added to gasoline, the laid alkyl creates a potential Organic lead hazard in tanks that store leaded Gasoline. Every storage teak that has stored leaded'gasoline must be mgw*d as having an additional hazard, toxic organic lead: This hazard can exist in tanks that were formerly wood to store leaded gasoline but, without cleaning, wom later switched to storage of a nonleaded product. It is mandatory Mat the Precautions and procedures described in Section 11 be followed when entering leaded gasoline storage tanks. A Ough the quantity'of leaded gasoline bcintig produced is dirnihishing because of federal mandates, the vast, num- bet of tanks that preaent an organic lead hazard will prob- ably continue to exist for some time because, in most cases, tanks were not cicaned and declared lead -hazard -free prior to the switch from the storage of leaded gasoline to the st+orar of nonleaded gasoline. Persons responsible for tank entry should treat MCh ¢esoline storage tank as a'.leaded- Sasoline storage tank Unless there is Conclusive evidence that it was never used to store leaded gasoline or that it was ClOwled and declared lead -hazard -flee before the switch to storage of nonleaded product, A lead-harlrad-fret tank is a leaded -gasoline storage tank that has been cleaned as cmfMg to Section 11, tested, and found to have o.o75 milliU= of Organic lead per cubic meter fi micrograms Per cubic foot) or toss.

Any attempt .to. test the tank before ar dutiny the Cleaning pmem tray result in unreliable infor- mation. Lead alkyls.

Lead alkyls have a vapor pressrun lower than- that of saw. line but ere volatile enough to produce potentially lethal concentrations of organic lead vapor In the atmosphere of the tank. When cleaning a leaded -gasoline storage tank and aft the tank has'been emptied of gasoline, the pri- mar7 source of the organic lead hazard is in the sludge at the bottom of the tank. Sludge is a sllury'of solids and liquids composed primarily of rust plus some water and entrained gasoline with organic lead. As the cleaning pro - CM prOgresses and the sludge is agitated, the more vola- We gasoline components containing lead alkyls vaporize Into the atmosphere. Lead aikylt are toxic by all three routes of exposure: inhalation, shin contact, and ingaation.

If dusts are present, respiratory protection and protective clothing should be wom. Examples of hazardous dusts are silica (from abrasive blasting . asbestos. lea4 chromam and zinc. The ACt3IH booldet Threshold LL01it Values and Biologicat Exposure Indices discusses various types of dust (See OSHA 29 Code of Federal Regulations 1910.1000 and Table Z-3 regarding mineral and nuisance dusts.) &4.4 PETROLEUM SUBSTANCES At 10 percent of the lower flammable limit, the hydro- carbon concentration in most cases exceeds ft threshold limit values for toxic materials (sec OSHA 29 .Code of Federal Regulations 1910.1000. Tattles Z-lA and Z-2). For example, benzene is hazardous at very low cence,urations (sec 3,4,6). Appmpriate personal protective equipment should be worn according to the recommendations of Sec- tions 6 and 7. The tnitalation of high concentrations of hydrocarbon vapor can cause symptoms of intoxication. These symp- toms range from diztiness to excitement to unconscious- ness; they are similar to those produced by alcohol or anesthetic am". it such effects occur, the individual should be removed to fresh sir. If the exposure is minor, fn;sh air or sniffing oxygen may result in rapid recovery: if brrwh- ing has stopped, artificial respiration should be started promptly. Inhalation of liquid hydrocarbon Splashes or droplets may cause unconreiousam or death. Medical ut- tendon should be obtained immediately. Exposure to petroleum substances should be minimized. For taut; maintenance, the following health precautions are suggested: a. Minimize sxln contact and breathing of vapors, b. Keep petroleum subsmnces uway.from the mouth; they can be harmful or fatal if swallowed. C. Keep work areas as clean' as possible and well venti- Iata d._ Clean up spills promptly. e.

Government health, safety, and environmental agencies are additional sources of information. 3AS WELDING FUMES 11e toxicity of Welding fumes depends on their compo- sition and concentration. The composition and quantity of fumes depends on the materials being welded. the compo- sitions of the rods and of any coatings or paints affected. the process being used, and the circtimstaaces of use. Toxic formes ate generated during the welding of metals coated with or containing alloys of load, zinc, cadmium, beryl- lium, and certain other metals_ Sonia paints may produce: toxic fumes when they arse heated with the welding torch. The potential healthh effects of welding fumes range in . type and severity depending on these factors; some effects can he extremely serious. Detailed i,nfunnation on weld- ing -fume toxicity and on appropriate protective rn msures, such as respirntora, can be ordained from the employer and by consulting the ACGIH booklet, r'hreahold lydrtlt Valmet and Biological Exposure Indices, OSHA regale. tions (sec. 29 Code of Federal Regulations Subpart q, "Welding.

Trained personnel with fire extinguishes or E'ure hoiea should be readily available. (Carbon dioxide extinguiahers should be avoided because static eltukeicity may be getitz- ated when they are discharged.) All sources of ignition, including smoking, welding, and other work that might be a source of ignition, should be eliminated from the area where flrimmable vapor may ba present or may travel. T'hc area should be lotpt free of all sources of ignition, such as electrical equipment (not meeting the arcs classification P=Cnlbed In NFPA 70) and. internal-combustion-englM egtilpmenE; until the tank is vapor -free and the sludge has been [removed 'Dien, if such equipment is used, It should be placed well away from the tank, preferably upwind, to minimize the ignition hazard.. No. work should be done if the direction of the wind might carry vapor into areas where it might produce a hazardous condition or when an electrical storm, either is In progress or is threatening. Even after as much product m poasiblc has been floated, out of the tank and vapor-frt eing has been completed, a flaamrmble condition may recur bmause of a cbange in temperature, agitation of the. sludge within the tank, or other reasons. If vacuum trucks are used to remove sludge from the tanks, they should be located outside the dike or a minimuin of 50 feet away Gild upwind where vapor from the storage tanit will not reach the internal-combustion .Cnginc. The exhaust vapor from this vacuum truck tank should be discharged downwind of the truck through a host of adequate size and -length. The vacuum -truck suc- tion and discharge hoses must be electrically bonded and grounded (see API Publication 2219). Unexpected sources of ignition often occur, so it is not sufficient merely to eliminate conditions known to be pos- sible soutces of ignition. Every effort must be made to avold the release of vapor near ground level during venti- lation and cleaning operations because most hydrocarbon vapors are heavier than air and wilt.treval along the ground, Possibly reaching an ignition source.

This prevents hydrocarbon vapors or liquids from entering the tank through the lines. Blinding off Is acet>taplished'by first closing all of the •valves nearest the tank, breaking the eesnnectiofl:s, and placing -blinds in all Of the limes. Blinds should be atroug enough and thick enough to withstand the maximum pressure that might be excited against d m. Before the blinds are installed, all lines between the tank and the location of the blind should be drained or flushed. FORM chamber on the tank should be opened and in- spected to ensure that the scale are intact and that product is not trapped in an area open to the tank, Dralas at the base of pipe risers to the foam chambers should be left open. ideating coils should be disconnected or blinded. Electrical connections to mixers and other electrical equipment inside the tank should be disconnected and tagged or locked out (see OSHA 29 Ca& of Federal Regulation, 1910.147), If the Dulk button[ is protected from corrosion externally by an impreasea mmat system, a bond wire should be used when aisconnectin8 pipe flangca, All tank ground cables and calahm clamps should be inapocted to casum grounding and bonding integrity. 4.0 Working on the Tank Roof and Near the Tank During Vapor -Freeing CAMOX: The atmosphere within a tank that has been emptied may be in the &aimablc range. Work on the roof and adjacent to the tank should be limited_ to what is essential. Workers should not be permitted to walk on intemal floating roofs daring vapor freeing (sea Section 10). When it is necessary for. worker: to waik on a tank roo& an inaprctltm should be made to determine what safety measures are needed. Planks should be used to distribute the; workers' weight if the roof is in questionabic condi- tion. Safety belts and 14411108 can be used, with a desig- nate' rescue worker standing by in case of an accident. When work is being performed on the outside of tacks that have contained sour stocks, workers should wear air - Supplied respiratory equipment in locations where expo- sure may oe mr. 4.7 VapQr-Fret:ing the Tank Alter dw tank has been emptied of residual product, blinded off, and electrically isolated, it should be freed of imardoux vapor, In the initial stage of vapor•freeing, while the tank still contains high concentrations of flammable vap-. mWutnnancx work. in the area around die tank and on the tank roof should be kept to a minimum. During the vapor -freeing process, the time during which the vapodair mixture In the.tank is iu the flammable range should be mininidW. Also, the vapor coming from the tank should be prevented from producing hazardous con ditiom outside the tank. Since most hydrocarbon vapor% are heavier than air. one way to reduce the possibility of vapor producing hazardous conditions outside the tank is to discharge the vapor at the top of the tank or at a high elevatlon. This allows for maximum dissipation of vapor and reduces the potential of flardmabic vapor reaching all Ignition source and of human exposure. The selection of an effoctive vapor -freeing method de- pends on many factors; the type of product stored in the tank, such no viscous crudes, gasoline, or liqua!•ied gases; the type of rant design, such m a cone -rook tank, an exter- nal or internal floating -roof tank. or a preccure stomgc tattle Ute tank location, such as below ground level: and the site of the tank, There are several methods for vapot. freeing ti tank: mechanical ventilation, ttcam ventilation, natural ventilation, and vapor displacement by flooding with water (see 117). 4.7.1 MECHANICAL VOMLATION 4.T.1.1 General Mechanical ventilation see normally the preferred method if ilte ranks design and location and the product in the tank permit it. An important feature of this method is that it can, depending on where and how the air movor is in- stalled, discharge vnnor at a high elevation, for example, near the roof line. Mechanical ventilation egttipment nor- mally consists of an eductor or blower (air mover) driven by an electric motor. air. or steam. no equipment mug be suitable for. hazardous locations and the air mover must be electrically bonded to the tank (see 4.3.3). if it is driven electrically, the requirements of 4.3.2 must be Bret. If it is driven by steam, the steam exhau.+t should not enter the tank unless the precautions of 4.7,2 are observed. 4.7.12 Mechanically VaporFreeing C0nG410of Tanks There are several rmthoda for mechanically vapor -fife. ing a cone -roof tank, auch as the following: a. Install an air mover on a roof manway. Vapor is dis- charged at the roof manway as fresh air enters the tank through a bottom shell manway. Witli the fx,ttom shell manway closed, the air mover should he started at a low delivery rate to create a slight negative preeeture inside the tank before the bottom shell manway is opened, This es- SENT BY 6- 2-93 ; 16.42 ;EMCON Northwest,Inc.- 2067710221 418 0 [7 SArt:• ENTnY AND CLF,ANINU Or PETrIOLFUYI SlUnAGE TANKS tablishes a pressure differential so that there is`no release of vapor at ground le,vcl when the bot[Onl shelf manway cover is removed.

Another roof manway is Opened, bUt the shell manways are kept eloeed. The Move vapor is drawn from new the bottom, flows up the tube through the air mover, and is discharged upward: If only one roof manway is available, it is possible to use a Smaller air mover pro- vided with all annularly-open support from the manway to allow fresh air entry. c. Place an air mover on the bottom shell manway and force air into the tank. allowing the vapod wr mixture to escape through the roof manway. Tlie roof manway should be kept closed until after the blower 4 installed in the shell ttianway. This minimizes the escape of�vapor at the shell manway. The roof manway is then opened, and the blower Is Started immediately. 4.7.1.3 MedtankoNy VgWp rrr;Ing op"Tap Roating-Root Tanka The methods for mcchalklu lly vague -fleeing open -top floating -roof tanks are as follows: a. The space above the floating roof may be mechani- cally ventilated by installing an air mover at the top of the tank and connecting it to a duct that is lowered near the floating roof. This duct allows the vapor to be discharged tit the top Of the shell perimeter. To vapor -free the space below the floating roof, an air mover is installedon a, shell manway. The air mOycr is positioned on the manway so that it draws air through the tank, It should preferably discharge Into an ell and a vertical duct to expel the vapor at as high a level as possible. After the air mover has been started at a low delivery rate, the remainitlg shell manways are opened, and the air mover is adjusted to rill capacity. b. The space below the floating roof may be ventilated . by installing an air mover.on the floadng-roof manway and connecting it to a vertical duct that discharges the vapor over the top of the tank shell. After the air mover haF been dtartcd, the shell rnanways are opened so that fresh stir is drawn into the tank. c. Rx small dialueter tanks with only one .,hctl manway. an air [Hover can be installed in the tnallway. To ventilate under the roof, air is drawn in through the open piping attachment nor71es and through the floating roofs angular sca) area. Floating tanks are usually aluippcd with a vent that opens when the roof is positioned on its legs. Air can be drawn in through this vent to provide additional venti- lation. 4,7.1A Mechanlcally Vapor-FhWngCovered Fioatittg-goof Tanks The methods for mechanically vapor -freeing covered floating -roof tanks arc as follows: a. Install on the fixed roof an air mover that removes the vapor between the fixed roof and the floating roof. The vapor is discharged. and flesh air is drown in through the shell eave line vents. With the shell mauwaya open, some vapor from beneath the floating roof ►via pass through the annular seal area and the column seals: b. Install an C&cmr an the fixed roof and lower a duct to the floating roof. Vapor above the floatinS roof is ex. haunted as fresh air enters the .,licit cave tine Vents. Vapor - freeing the space beneaththe floating roof can be accomplished as descn'bed in 4,7.1.3. Item b. 4.7.2 WHAM VENTILATION Steam ventilation may be advantageous in speoife cases, but its use introduces some spacial hazards.- CAU27ON: Sham ventilation should be avoided when suitable alternatives are available. Steam jets are prolific generators of static charges on the nozzle tend on objects that the steam impinges. This can Cause Sparks and the ignition of flammable vapor. The Pipe or nozzle through which the atcam discharges must be electrically bonded'to the lank; however. ft will not prevent a static charge from being geauaW a8er the steam leaves the aoazle. A charge may ae cWUMte on an electri. tally insulated object irt.,idc the tank and cause Sprjkillg. Therefore, all conductive. i L%dated objects Subject to steam impingement or condensation should also be electrically bonded to the tank shell (see API Publication 2t1A3 and NFPA 77). , i'o be effecd atcaem must be Introduced at a rate that is high enough to Min the temperature throughout the interior of the tank to at least 170*F (770Q.

Steam vapor -freeing may be appropriate for small tattles having an initial vapotlair atmosphere tint is known to be vapor -rich (above the upper flammable limit). By injecting purge steam through an enclosed piping oonnectiaa, the tank atmosphcre is displaced by Steam and never goes through the flammable range. For this method to be effec- tive in rcmaving all vapor. the steam rate must be high enough to produce a good steam plums from the roof tnanway, which should ideally be located oppaaitc the Steam inlet to ensure a eompleee purge of the task's intc- dor, C7.3 NATURAL VEPPIILATION Natural ventilation should be avoided if other ttbethods are available because vapor may drift to a source of igni- tion. Natural ventilation simply entails removing the roof and shell manway covers and allowing the tank to stood idlo until natural ventilation makes the tank vapor -free, it is a slow process. At least at the start. the dense vapor will flow from the sbeli manway. As the ventilation progreesm. the now of vapor may reverse and- flow- frarn the roof manway because of changes in the density of the vapor and in wind velocity. if this occurs, it will stoat lik ly be. at the end of the operation. Bteoause drift and concentra- tion Of vapor are unpredictable, only pi annel wearing proper protective clothing and equipment should be al- lowed in the area to stake occasional vapor tests. 4.7.4 VAPIOR-FREEING UNDERGROUND STORAGE TANKG Ventilating uaderground storage Umks can present un- usual problems because they often have few or no manways. Most underground tanim of the service -station type do not have manways. Some of these tanks are now being entered and arc receiving Inteder lining to prolong their useful life. For most tanks this involves cold- cutting an aoccas manway, using nonsparking and explogion-proof equipment, so that workers can enter the tank. All electri- cal equipment used in this process must most the require- ments of 4.3.1.4.3.2, and 4.3.3. CAUTION, Before the access hale is cut, all remaining product must btc remavect, the tank most be ventilated to 10 percent of the lower flammable limit or IV% and it must remain so lhrougheut the cutting operation. When there is no manway, the ventilating, process is Complicated because only tin; tank Fill -line (drop Mbe) and vent -line connections are available for vapor -freeing. An eductor installed on the fill tube line will remove vapor at the fill line and allow fresh air to enter at the vent connec. tion_ Alternatively, fresh air can be pompW into the tank at the.fill.tube connection, and vapor Can be discharged at the.vent connection. CAUTION.- Scc 12.6 about the hazards of using compressed air. Where contaminated water can be handled, eonsidcr- Won should be given to tilling the tank with water to remove hydmcaftn liquid and vapor. Another method of vapor -freeing underground storage tanks that do not have manways is to empty the tank, as much. as possible, and then inert the atmosph= with, for exaittple, nitrogen or carbon dioxide, This should remove flammable vapor and oxygen, marking the job of cutting (be' access manway leas hazardous. After the access manuay has been cut, the tank must be thoroughly venti- lated to remove the inert gas and any remaining hydrocar- bon vapor - CAUTION: After the tank has been thoroughly ventilated and before personnel Caret the tank, it must be tested ac- cording to Section 6.

Open -top floating goofs have tctW-encload cottlpan- meats for flotation; these may be peripheral pontoons or a complete double deck. Open -top steel pans have also been, used. Open -top tanks have no fi%W roof over the floating roof. There are several methods of providing buoyancy for covered floating r9ofe, including aluminum -rube pontoons and an inherently buoyant foam crtclosed in metal or plas- tic sheeting to form the deck Sumo internal roofs are simple steel parts or pontoons. Covered floating-mf tanks have fixed roofs that forte vapor spaces between the floating and fixed roofs. The seals that close the annular space between the float- ing roof and the Abell may be flexible foam -filled bags, flexible wipers, or metallic shoes. Primary and secondary seals with an intermediate vapor space are often used on open4op floating -roof ta&s. 10.2.1 HYDROCARBON ENTRAPMENT Any of those buoyancy and'=ding devices may retain hydrocarbon and leak aitzr the tank eppc,n U, be vapor - free and after satisfactory vapor -indicator tests have been obtained. Hydrocarbon may also be trapped in the roof - support legs. Before deeming begins on a floating -roof tents, supervi- sory personnel should review and be familiar with the roof dMign; in PattICULU. the flotation and Sealing doviers used should be studied. Pontoons should be inspected, and if they contain hydrocarbons, the hydrocmbo,ta should be re- moved to mtntmize the potential for fire, oxygen; and tox- icity hazards. CAMON: Liquids in pontoons may also cm= a physical hazard because the roof and roof icga am not designed to carry additional weight. 10.0 INPORMATiON ON CUNDI'MN OF FLOATING ROOFS Available information on the leakage and retention of hydrocarbon in roofs of the type to be worked on should SENT BY: 6- 2-93 ; 16:56 ;EMCON Northwest, hc.- 2067710221;#28 • LJ it SAM ENTRY AW CteAMW OF peTRMEUM SlnuGe Tuxes —� ^�21 be rovicwed- In addition, particularly in older tanks, the various services in which the tank has bcco aced should be studied. 10.2.3 EFFECTS OF FLOATING ROOF DESIGN ON CLEANING AeTpAM The. restricted space under floating roofs resting oa legs should be taken into account wheb pleasing work and gas testing.

SECTION 11—CLEANING LF-AADED-GASOUNE MRAGE TANKS 11.1 General All tanks that have been Used to store leaded gasoline present a potential organic -lead hazard to workers t±ngaged in cleaning them (see 3,4.2), This applies to undergnxmd tanks of the servim-station type as Well as to large bulk storage tanks in terminals and refineries, It also applies to t"ks that have at one time stored leaded gasolim but were switched to unleaded -gasoline storage without being cleaned. Oven if such a tank has been in unleaded -product service for many yam, the organic -lead hazard can remain indefinitely, primarily in the sludge on the tank bottom. Aftena leaded -gasoline storage tank has been thoroughly cleaned and tested with a lead -in -air analyzer and has been determincd to be lead-hazard-ft'ee, it may be ttrated as a nonleaded -product storage tank except that it should xkct be used to store edibles or potables for animal or human' consumption. The term lead -hazard free is defined in 11.2, ff the tank is 'dismantled, the steel trust not be used for any purpose that involves contact with edibles or potables (sec APf Publication 2202). The safety precautions and procedures for cleaning leaded -gasoline storage tanks include all of the procedures for cleaning nonleaded -product tanks plus additional pre- cautions.

Requirements for persa" clothing are similar to arose for cleaning a nonleaded -product tank, except that they remain in effect until after the tank has been cleaned (see 7.1). Workers should wear clean clothing from the skin out each day and wear impervious boots and gloves. if clothing becomes contaminated with sludge. for example. if a worker falls in it, the worker should leave the tank, remove the clothing, shower. put on clean .clothing, and resume work (see 7.1 and 7.2). c. ' After the tank has been cleaned and dried, the tank atmosphere should be tested with a lead -in -sir analyzer (see 11.3, 11.4. and 11.5). d. Sludge from the tannin tnast be disposed of according to government regulations (see 11.6). e. If hot work is to be done after the tank has beat cleaned, AP1 Publications 2= and 2207 shmdd be consulted. 11.2 Lee"a2rd-Free Tank A tank is described as lead-hazurd free when the fo1- lowing conditions are satisfied: a. The tank has been cleaned, and all sludge has been removed. b. Loosely adherent material has beers removed from the Pan of the rant that was in direct contact with the sludge, normally the tank bottom and perhaps the aide walls of the first shell ring. c. The tank is essentially dry and free from liquid or puddles. d. A -lead -in -air test, which must be made after the tank has been cleaned and dried, indicates that the organic kad- in-air concentration is equal to or less than liar permissible exposure limit (see 11.5). The tank is fiat lead-Hazard-free,lf. after cleaning, any of the following conditions prevail: a. The lead -in -air test has not been made, or the test re- sults exceed the pertnissibie exposure limit b. Surfaces of the tank that were in contact with lead material are healed, for example. by cutting, burning, or welding, unless all rust, scale, and other foreign material have been removed to expose bane metal at the ar sas to be treated. C. The tank contains absorbent materials that may release organic lead. d The tank has a leaking bottom. Frequent. lead -in -air rats should be made to ensure safe conditions when re. Fairs are made. 11.3 Lead+i-Mr Analywr The lead -in -air analyzer used to measure the conccntm- aun of lead in air must measure organic lead. not inorganic lead (see 5.5). The maauNCturer's operating instructions mast be followed. The lead -in -sir analyzer should not be used before or during tank cleaning; the results are meaningless and will not reflect the true condition of the tank. it cannot be test to determine whether a tank has been in leaded service. A lead -in -air analysis should be made after the tank has been cleaned, `after all of the. sludge has been removed, after loosely adherent materials that were in contact with the sludge have beelt removed, and after the tank is essen- tially dry and free of liquids or puddles ' (see 11.4 and 11.5). The, combnatible-Su -detector does not give an indica- tion of organic -lead concentration; it must rat bus used as a substitute for a lead -in -sir analyzer. . 11 A Lead -In -Air S mpling PrOCedure and LoaWon The person making the lead--in-air testa should wear positive-prusure full-facepiecc respiratory equipment acid Protective clothing as prescribed for tank cleaners. Samples for lead -in -air analysis should not be .taken during forged ventilation because samples taken at this time will be di- luted and not representntivc of tttt real conditions that could be encountered during subsequent work. Forced ven- tita4ion should be stopped a minimum of i� minutes before the test is made., To obtain rapresculittive samples of the atmosphere within the tank, tine sarnplas should be collected while the tester is walking near the inside periphery of the tank, walking diagonally across it, and walking in areas sus- pcctcd of emitting organic -lead vapor. 11,5 Intetpl'eMIon of results The current standard under the OSSHA Occupational Safety and Health Standards, 29 Code of Federal Regula lions 1910.147; Subpart Z "Toxic ttnd HwArdous Sub- staruw," 1910.1000, Table Z-lA, limits personnel exposure to the organic -lead compounds tetraethyl and tetramethyl lead to a time-wuighted average of 0.075 milligrams per cubic meter (2 micrograms per cubic foot) during any 8- hour shift in a 40-hour week.

Disposal Under ttto Rtaoelrcc GonsQrvaWn and Rccovtary Act Regulations enacted under the Resource Conservation and Recovery Act (RCRA) require sludge from leaded - ,gasoline tanks to be stored, shipped, treated, and disposed of in an envimnmentally approved manner. The general requirements of RCRA include those specified in 11.7.1 through 11.7.7. 11.7.1 NOTIFICATION AND APPLICATION All companies that gemme, store, transport, treat, or dispose of hazardous• wastes must file with EPA a form notifying the agency of those activities. Unless notifica- tion has been given to EPA. waste may not- be stored, transported, treated. or disposed of. All companies that store,, rurat or dispose of sludge moat apply to EPA for a permit to continue to do so. 11,7.2 DEVELOPMENT CP A PLAN Each company that generates sludge must develop a plan for the storage. treatment., and disposal of Its sludge. If storage, treatment, or dispose! is to occur on site, the Company is then considered, for all practical purposos, to be the operator of a hazardoua-waste-management facility and must obtain a permit to operate such a facility. If the company decides to dispose of the sludge off site, ono per mit is required as long as the company stores the material in appropriate containers and ships it off site. within 90 days Of isolation, accumulation, or separation; howcvcr, 40 Code of Federal Re,ggdatimts 262.34 sp%ifies swmge requirements before shipment. 11.7.3 SHIPPING HAZARDOUS WAS'l1= Before shipping an EPA toxic hazardous watts to an offshe facility, the company that ,generated the waste is required to prepare and sign a ,manifest that identifies the company. identifies the waste by its EPA .tnd Depar nw,t of "Transportation hazardous waste number and name, identifies the offske fadlity that will handle the material. And specifies the total quantity in the shipment. The Com- pany should be eartain that the fivmportcr and the selected facility have EPA identification nuritbm and permits to engage in hazardoua-waste-management activities. 11.7,4 RECORDKEEPING AND REPORTING The regulations impose extensive recordkeeping and reporting tequiresments. Companies that . genuate sludge must maintain copies of all manifest documgmts 'and records and must also submit annual reports. 11.7.5 REOUIREMENTS FOR TRANSPORTERS Persons engaged ir, the off -site transportation of the sludge must comply with EPA's specific regulations for the transportation of hazardous wastes, which govern 'noti- fication, manifest, .and recordkeeping.

Personnel should fmnillaaiae thom"lve* with them per. dares as described in, the pmeading sections of ;iris publl- Cation. 12.2 _�e of C%as-FMCing Promdure to Be Used The procedure to be followed in gas -freeing a- liquefied petroleum gas storage tank varies with the type of installa- tion and is usually .determined by tha tank's location. In bulk plants and i stalladons with limited facilities, the procedure is different from that in r rawrias and large installations, At large installations, flare systetus and high. volume water supplies are usually available, In tlto can of terminal and bulk -plant installations, the product being handled must be kept dry and ie normally fr= tom rCSi. due. Therefore, the gas-fmoing procedure employing ,%,a- ter,flooding and washing may not be applicable. 12.3 Emptying the Tank :'he tank should be blocked off. from other equipment except for the ptnupout line. and then the tank should be emptied by puznPinl; out. If the pumpout connection is above the bottom of the tank, water should he introduced under pressure into the bcs tom of the tank to float residual hydrocarbons to the pumpewat connection while pcunping continues, Water should not be introduced at a rate greater than the PlImPoitt rate, A check valve should be provided to Prevent a backflow of hydrocarbons into the water Uft When water flushing is completed, the water line should be disconnected because the check valve may leak. When the hydrocarbons have been pumped out, the water should be drained slowly through the water drawoff. system. CAU770N. While the water is being drained, it is earenttial that the water -draw valve be watched until gas appears and the valve is closed. 12.4 Deprasurizing After all liquid has been pumped out, the tank will con- tain gas under pressure. The method seketed for venting the gas should be one that results in the tttininw n possible concentration of gas in the surrounding atmosphere. Con- trol of ignition sources, as discussed in 4.3, is also essentiaL Flaring and venting to the atmosphere are the. two pre- fcrrcd methods of depressurizing tanks.. The venting method for a particular tank depends on local conditions. Flare ar gan-collection'systems should be used wheie they exist b9oause flaring at a safe location Climinates the possibility of flammable mixtures being formed in the area. At locations having no such systems, a simple flare can be eonsttwtod by connecting a pipe to the outlet of ona of the vulvas on the rank. This pipe should be routed to an area safely clear of all combustible materials, including shrubs, weeds, and grass. The gas may be burned at .the and of a horizontal pipe equipped with a flarre ar- restot, or an elbow Ind nipple mazy be. installed to direct the flaw upward The rate of burning must be controlled to achieve a stable flame attd to prevent overheating of any. thing in the area, Suitable precautions should be taken to Prevent roe vented gas from exdnguisshing sad forming a downwind vapor cloud. Venting at an elevation above the tank will disperse the gas with a low probability of forming flammable mixtures in the surrounding area. To vent above the tank, use the, follpwing procedures: a. Close a valve on a top tank nozzle and isolate any associated piping, b. Disconnect the piping gownstream of the valve. c. Install a riser or vent stack on the valve approximately 8 feet above the top of the tank. cL Partially open the valve. c, Slowly depressurize the tank, 12.5 Blinding After the,tank has beau depressurized. connections to other tattles, pumps, and facilities should be blinded off adjacent to tine tank nozzles (see 4.5). 12.6 Gas-iFrwlrjg Gas-frcOhIg may be achieved by water flooding (scc 117), by purging with an inert gas followed by an air Purge, or by using the ventilating methods of 4.7. Direct purging with compressed air should be avoided because an air 5treanl Containing ruck Seale, or Moieturr. causes static electrification. which may 100Conl6 an ignition source (see 6.1 and 62 of N R..A 77). 12.7 Gas fail by Water Flooding Some liquefied gas storage hunks or Their foundations are not designed to be completely tglled with water.

I would offer the following comments in response to the pipeline permit which you have forwarded: 1. While paragraph (1) of the permit specifies $300.00 payment for the first ten-year period and $150.00 for each subsequent ten year period while the permit is in effect, the Railroad reserves the right to change said, charge at any time while the permit is in effect on thirty (30) days written notice. This is in addition to the Railroad's right of termination under paragraph (9). 2; Note that the permit requires two (2) days notice of any work to be done by the City. 3. The permit provides for the payment of any and all expenses incurred by the Railroad during the City's installation of.the line. 4. The City is�required as part of the permit to release in. advance the Railroad for any liability for damage or destruction of the City's facility. You should also. note that the indemnification agreement required by the Railroad requires an indemnification by the City ; regardless of whether or not the Railroad's losses are'. brought about by the negligence "of the Railroad, its officers, its agen.ts, servants or employees, or be contributed to by such negligence." 5. The permit contains a provision in paragraph (8) that nothing in the permit will "imply or import a covenant ... for quiet enjoyment". What this means is that if • • Patrick Wilson/City of Edmonds Burlington Northern Waterline Permit March 11, 1985 - 2 there is any interference with the use of the permit or with the City's waterline, we have no recourse against the Railroad. 6. Finally, should note that this permit may be cancelled on thirty (30) days written notice by the railroad. It' may cancel for any reason or no reason. In summary, this permit is one sided,."illusory" and totally aimed at protecting the interests of the Railroad. Your letter of March 8 implied that my review is necessary by March 12, 1985 at 9:30 A.M. You further indicate the bidding of the job is emminent, and the document must by approved by the City Council by Tuesday, March 19, 1985 if at all possible. In this time frame it is obviously impossible for me to negotiate or advise you regarding alternative provisions and to effectively have them reviewed by the Railroad. I note that you received communication from Burlington Northern on March 7, 1985. ,.It is my opinion that the City would acquire the bare right to place a waterline over the Burlington Northern track. For this . bare right, it pays .the sum of $300.00. We incur unknown liabilities by virtue of an overly broad indemnification provisions which is heavily weighted against the City's interest. Practically, however, I realize that this may be the only feasible alternative for the City. If that is the case, you should so advise the Council. If there is any room for discussion and negotiation, I would recommend that: 1. We attempt to ease the provisions.of the.indemnification provision, particularly.those provisions which require the City to indemnify the Railroad from losses due to their own negligence and which remove their duty of contribution in the event that negligence of both the City and'the Railroad brings about the loss. 2. The provisions regarding ".quiet enjoyment" be addressed so that the..City has some assurance that.it may retain its.line in place without interference with its use.' Obviously, one of the ,answers to my concerns is that the.City is paying a mere $300.00 for.ten years worth of right. If it is your professional opinion that (1) this agreement cannot be amended, and.(2) that is the only practical way to get the Patrick Wilson/City of Edmonds Burlington Northern Waterline Permit March 11, 1985 - 3 waterline across the Railroad right-of-way, you should so advise the Council.

NAUGHTEN MAYOR ?01�V RECD 3 aN 0 41985 ENGINEERING I am writing to you in order to update you on the status of the water loop construction project. The City of Edmonds is making definite plans to proceed with the project by Spring of 1985. It is our position that the benefits of this project justify proceeding with construction as soon as possible. It is the goal of the City to work cooperatively with the Port of Edmonds and with Union Oil, and to share the costs evenly. It is estimated that the total project cost will be $60,000 and that each of the three participants would therefore contribute $20,000. Preliminary verbal indications from Union Oil have been positive, although the final decision has yet to be made at the corporate headquarters. A written response from Union Oil is forthcoming. In April, 1984, the Edmonds City Council adopted a resolution of intent to form an LID (local improvement district) for the purposes of funding this project. Under the LID process the Port and Union Oil would be assessed the total cost of the water loop project. With additional legal and engineering fees, the total cost could well exceed $100,000. It seems that all three of us — the City, Union Oil, and the Port — would greatly benefit if a simple cost -sharing plan was adopted. I hope that you share this view and that you could choose an alternative which reduces the costs and simplifies the project. The LID process, as outlined by State and local laws, requires that the next step commence at the beginning of February, 1985. Completing the water loop system will improve water flows on the waterfront from 50% to 100%, and enhance the safety and welfare of the people and facilities being served. Our goal is'to work together on these matters as they arise and resolve problems with the minimum cost and conflict. 0 The City is hoping to receive a response from the Port and Union Oil before the end of January. Thank you, and a Happy New Year. LARRY S.

ENVIRONMENTAL CHECKLIST Purpose of checklist: The State Environmental Policy Act (SEPA), chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring Preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply." Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Use of checIdistfor nonproject proposals: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROIECT ACTIONS (part D). .

Give brief; complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) Pursuant to chapter 173-340 WAC, Model Toxics Control Act (MICA), Unocal proposes to perform an interim remedial action to reduce potential threats to human health and the environment and to provide additional information for a feasibility study and subsequent design of a cleanup action for the site. Specifically, asphalt material and petroleum -contaminated soil will be removed from Detention Basin No. 1 and shipped off site for recycling, treatment, and/or disposal. Petroleum -contaminated soil from the Southwest Lower Yard will also be excavated and shipped off site for recycling, treatment and/or disposal. The Unocal Edmonds Terminal is approximately 47 acres: the upper yard (former tank farm) is approximately 25 acres and the lower yard approximately 22 acres. Storm water Detention Basin No. 1 encompasses approximately 2.7 acres in the northern -most comer of the Terminal's lower yard. Asphalt material and petroleum -contaminated soil will be removed from the approximately 180-foot by 630-foot storm water detention basin. Up to 30,000 cubic feet of material may require removal, at excavation depths ranging from 6 to 8 feet. Water (consisting of detained storm water and groundwater) removed from the basin during excavation activities will be transferred to adjacent Detention Basin No. 2, the Terminal's oil/water separator, or toa holding tank for subsequent discharge pursuant to conditions of the Terminal's NPDES discharge permit. An estimate 10,000 cubic yards of petroleum -contaminated soil will be removed from the southern end of the lower yard (Southwest Lower Yard). The excavation will be backfilled with clean imported fill and graded into the surrounding contours. 2 TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY 12. Location of the proposal. Give sufficient information for a -person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The Unocal Edmonds Terminal is located at 11720 Unoco Road in Edmonds, WA; Section 23, and the northwest quarter of the northeast quarter of Section 26, Township 27 North, Range 3 East, W.M., in Snohomish County, WA. Site plan and vicinity map/topographic map are attached. B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site (circle one): B rolling, hilly, steep slopes, mountainous, other ...... Lower yard is relatively flat; Detention Basin No. 1 has sloped berms surrounding the basin. b. What is the steepest slope on the site (approximate percent slope)? < 2% in lower yard C. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The site is underlain by fill, alluvium, and a sequence of glacial and pre -glacial deposits. In the lower yard, grade fill consists primarily of sand and gravel mixtures, with small amounts of silt. Finer grade fill is also present. It varies in composition, but generally consists of sand and silt mixtures with varying amounts of gravel, organic material and miscellaneous debris. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No. e. Describe the purpose, type, and approximate qua tities of any filling or grading proposed. Indicate source of See previous Item A. 11. project description for approximate quantities and areas involved. An estimated 10,000 cubic yards of clean, imported fill will be required to backfill the Southwest Lower Yard excavation. The surface will be roughly graded into surrounding contours. Source of fill is not yet identified. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Potential erosion during construction if work occurs during rainy periods. Erosion will be controlled per an erosion and sedimentation control plan. TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Pavement and buildings currently cover approximately 8 % of the site. The interim action will not change this percentage; i.e., no additional imperious cover will be placed as part of the interim action. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Prepare and implement an erosion and sedimentation control plan.

Subject: INTERIM REMEDIAL ACTION, FORMER UNOCAL FUEL TERMINAL SITE Dear Mr. Staton: The City of Edmonds Planning Division has reviewed your request dated November 14, 2006 (received on November 20, 2006), for an exemption from the requirement to obtain a Shoreline Substantial Development Permit (SDP). As described in your letter, the project is to conduct an interim remedial action at the former Unocal Edmonds Terminal consisting of removing contaminated sediment from a portion of Willow Creek. Upon review of the proposed replacement and repair work as outlined in your letter of November 14, 2006, including the enclosed site plans and project description, the City has concluded that the proposed work is exempt from the need to obtain a Shoreline Substantial Development Permit pursuant to WAC Section 173-27-040(3). This exemption applies to "hazardous substance remedial actions" covered by an Agreed Order such as the Order in effect for this site. Note that this exemption only applies to the activities within the jurisdiction of the Shoreline Management Act, including areas within 200 feet of the shoreline and areas within the boundaries of the Edmonds Marsh. Portions of the project within Willow Creek and the immediately adjoining portions of the Unocal "lower yard" generally fall within this jurisdiction. Other portions of the project outside • Incorporated August 11, 1890 • sM-2006-147 Page 2 . of this jurisdiction are not covered by the Shoreline Master Program and are therefore not regulated by the Shoreline Master Program. Although the exemption means that a SDP is not required for this project, the project must still comply with the substantive requirements of the Shoreline Management Act and the City of Edmonds Shoreline Master Program. Since the agreed order addressing remediation of the former Unocal Edmonds Terminal has been previously reviewed and found to be consistent with the City's SMP, proceeding with the proposed interim remedial action is appropriate. This exemption is issued under the following assumptions and conditions: The City conditions its approval on the State Department of Ecology approving the proposed "interim action work plan" referenced toward the bottom of page three of your November 14, 2006, letter. A copy of the "interim action work plan" approved by DOE shall be provided to the City prior to beginning the work. 2. The project shall be conducted according to the conditions and stipulations outlined in your November 14, 2006, letter. 3. The applicant is responsible for obtaining all other pertinent permits and approvals, including the requirement to obtain a City of Edmonds grading permit through the Edmonds Building Division. Note that Best Management Practices for erosion control shall be utilized during the project; any questions regarding City standards for erosion control should be addressed to the City of Edmonds Engineering Division, 425-771-0220. Related to the request contained in the letter, we have also been requested to respond to how the City's Critical Areas Ordinance (CAO) applies to the project. Under the City of Edmonds CAO, the Edmonds Marsh is a designated Category 1 wetland and Willow Creek is a Type F, anadromous fishbearing stream. Both of these are regulated critical areas. Standard buffer widths for Category 1 wetlands are 200 feet; buffers for Type F streams with anadromous fish are 100 feet. As described above, a significant portion of the project area is within a critical area or critical area buffer. A critical areas report will be required to support the activities proposed as part of the remediation project. However, it is expected that the "interim action work plan" that is approved by the Department of Ecology could satisfy this requirement. The normal way to gain critical areas approval for a project of this type would be to file an application for a grading permit with the City of Edmonds Building Division, accompanying the permit application with a copy of the DOE -approved interim action work plan. If not specifically noted in the work plan, you should also provided SM-2006-147 Page 3 documentation on who prepared the plan together with their qualifications (the City's CAO requires that studies are prepared by a "Qualified Professional," such as a biologist with experience in preparing reports for the relevant type of habitat). Should there be a change in any of the work described in the request for a shorelines exemption, or in the assumptions underlying the exemption, the applicant is responsible for contacting the City to verify whether any changes in permitting will be necessary. If you have any further questions regarding this matter, please do not hesitate to contact me at 425-771-0220.

ENVIRONMENTAL CHECKLIST Purpose of checklist: The State Environmental Policy Act (SEPA), chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply." Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Use of checklist for nonproject proposals: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) Pursuant to chapter 173-340 WAC, Model Toxics Control Act (MTCA), Unocal proposes to perform interim remedial actions to reduce potential threats to human health and the environment and to provide additional information for a feasibility study and subsequent design of a cleanup action for the site. Specifically, petroleum -contaminated soil will be removed from the upper yard %area of the Terminal and shipped off site for thermal treatment or disposal; heavy -metal -contaminated surface soil will be removed from areas of the upper and lower yard and shipped off site for disposal; and free petroleum product and associated petroleum contaminated soil will be removed from select areas of the lower yard and shipped off site for recycling, treatment and/or disposal. The Unocal Edmonds Terminal is approximately 47 acres: the upper yard is approximately 25 acres and the lower yard approximately 22 acres. Petroleum -contaminated soil will be removed from an estimated 115,000 square feet of the upper yard; estimated soil volume is 15,000 cubic yards and estimated excavation depths range from 2 to 5 feet below ground surface. Metals - contaminated surface soil will be removed from an estimated 75,000 square feet of the upper and lower yard; estimated soil volume is 1400 cubic yards; average excavation depth is 0.5 feet. Petroleum -contaminated soil will be removed from an estimated 40,500 square feet of the lower yard; estimated soil volume is 11,500 cubic yards; estimated excavation depth is 7.5 feet below ground surface. It is anticipated that approximately half this soil volume (►*,V501c—vliic ya ds) will be returned to the lower yard excavations. Prior to backfilling, excavations in the lower yard will remain open for approximately I month to allow for removal of free/floating petroleum product. Product collecting in the excavations will be recovered by skimming and transferred into a temporary tank for subsequent shipment off site. Groundwater removed from the excavations during skimming will be transferred to a temporary tank. After testing for suitability, the groundwater will be discharge to an on -site oil/water separator. Volume of product/groundwater to be removed from the lower yard excavations is estimated at 2,000 gallons. 12. Location of the proposal.
