The PCS was excavated ftom the floor of the former hosting oil tank hold and from an area to the south of the former UST where the surficial release reportedly occurred. The tank hold excavation eximded to a depth of approximately ten (10) feet benesih ground surface and was approximately fifteen (15) feet by twelve (12) feet wide at the ground sut*= Petroleum - soil was removed to a depth of approximately seven (7) feet beneath ground surface in the southom excavation. The contaminated soil was stockpiled on visqueen and later loaded into trueks and transported to a thermal desorption t mitment facility in Everett, Washington. 6- %W dw 40 Results of sampling and testing of selected soil samples collected from the flom and sidewalk of the former tank hold and the southern excavation confirmed that soil in these area is now compatible with currant WDOE Method A cleanup levels for diesel -rangy petroleum Qomta:q dints. Relying upon the results of sampling and testing completed thus far, it would appear that no additional action with regard to soil would be required by local, state, or federal agencies.

DURING AND AFTER CONSTRUCTION, ALL PERSONS ENGAGING IN DEVELOPMENT ACTIVITIES SHALL PREVENT OR MINIMIZE EROSION AND SEDIMENTATION ON —SITE AND SHALL PROTECT PROPERTIES AND WATER COURSES DOWNSTREAM FROM THE SITE FROM EROSION DUE TO INCREASES IN THE VOLUME, VELOCITY AND PEAK FLOW RATE OF STORM WATER RUNOFF FROM THE SITE. B. THE APPLICANT SHALL PREVENT THE TRANSPORT OF SEDIMENT ONTO ADJACENT PROPERTIES. C. THE APPLICANT SHALL APPLY BMPs FROM THE SNOHOMISH COUNTY DRAINAGE MANUAL OR AS APPROVED BY THE DIRECTOR TO PREVENT OR MINIMIZE THE TRANSPORT OF SEDIMENT ONTO PAVED SURFACES DURING CONSTRUCTION, AND IF SEDIMENT IS TRANSPORTED ONTO A PAVED SURFACE, TO CLEAN THE PAVED SURFACE AT THE END OF EACH DAY. D. THE APPLICANT SHALL DENUDE AREAS AND SOIL STOCKPILES AS FOLLOWS: (1) FROM OCTOBER 1 TO APRIL 30, NO SOIL MAY REMAIN EXPOSED FOR MORE THAN 2 DAYS. FROM MAY 1 TO SEPTEMBER 30, NO SOIL MAY REMAIN EXPOSED FOR MORE THAN 7 DAYS. ON PORTIONS OF THE SITE WHERE ACTIVE GRADING IS IN PROGRESS, THE DIRECTOR MAY. EXTEND THE DEADLINE FOR SOIL STABILIZATION UPON DETERMINING THAT THE LIKELIHOOD OF EROSION IMPACTS IS LOW BASED ON THE TYPE AND AMOUNT OF SOIL EXPOSED, SITE TOPOGRAPHY, THE POTENTIAL FOR DISCHARGE TO CRITICAL AREAS AND LAKES, AND OTHER FACTORS. UPON FINDING A RISK OF EROSION, THE APPLICANT SHALL IMMEDIATELY APPLY SOIL STABILIZATION, REGARDLESS OF ANY PREVIOUSLY ESTABLISHED DEADLINE, AND THE DIRECTOR MAY REQUIRE IMMEDIATE STABILIZATION AT ANY TIME FOR THIS PURPOSE. THE APPLICANT SHALL KEEP MATERIALS, EQUIPMENT, AND OTHER RESOURCES ON SITE AT ALL TIMES, IN ADEQUATE QUANTITIES TO IMMEDIATELY STABILIZE ALL SOIL. (2)DENUDED AREAS SHALL BE COVERED BY MULCH, SOD, PLASTIC OR OTHER BMP IN THE SNOHOMISH COUNTY DRAINAGE MANUAL OR APPROVED BY THE DIRECTOR. (3)SOIL STOCKPILES SHALL BE STABILIZED OR PROTECTED WITH SEDIMENT RETENTION BMPS WITHIN 24 HOURS OF FORMATION TO PREVENT SOIL LOSS. (4) GRADING AND CONSTRUCTION SHALL BE TIMED AND CONDUCTED IN STAGES TO MINIMIZE SOIL EXPOSURE. E. THE APPLICANT MAY REMOVE ALL TEMPORARY EROSION AND SEDIMENTATION CONTROL BMPs WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION OR AFTER THEY ARE NO LONGER NECESSARY. F. BEFORE CONSTRUCTION ACCEPTANCE BY THE COUNTY, THE APPLICANT SHALL ESTABLISH A PERMANENT VEGETATIVE GROUND COVER TO CONTROL SOIL EROSION AND TO SURVIVE SEVER WEATHER CONDITIONS ON ALL AREAS OF LAND DISTURBANCE NOT OTHERWISE PERMANENTLY STABILIZED BY IMPERVIOUS SURFACES OR OTHER MEANS.

THE APPLICANT SHALL MAINTAIN AND REPAIR AS NECESSARY ALL TEMPORARY AND PERMANENT EROSION AND SEDIMENTATION CONTROL BMPs TO ASSURE THEIR CONTINUED PERFORMANCE THROUGH CONSTRUCTION ACCEPTANCE AND EXTENDING TO THE RELEASE OF ALL ASSOCIATED WARRANTY SECURITY AND MAINTENANCE SECURITY. 2 ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION IS ACHIEVED OR AFTER THE TEMPORARY BMP ARE NO LONGER NEEDED. TRAPPED SEDIMENT SHALL BE REMOVED OR STABILIZED ON SITE. DISTUBED SOIL AREAS RESULTING FROM REMOVAL SHALL BE PERMANENTLY STABILIZED. 3. A WHEEL WASH PAD WILL BE PROVIDED AS THE SEASON DICTATES. 4. THE APPLICANT ::HALL IMPLEMENT FULLY THE EROSION AND SEDIMENTATION CONTROL PLAN AT EACH STAGE OF SITE DEVELOPMENT. TEMPORARY FILTER FABRIC FENCE: 1. THE FILTER FABRIC SHALL BE PURCHASED IN A CONTINUOUS ROLL CUT TO THE LENGTH OF THE BARRIER TO AVOID USE OF JOINTS. WHEN JOINTS ARE NECESSARY, FILTER CLOTH SHALL BE SPLICED TOGETHER ONLY AT A SUPPORT POST, WITH A MINIMUM 6 INCH OVERLAP, AND BOTH ENDS SECURELY FASTENED TO THE POST. 2. POSTS SHALL BE SPACED A MAXIMUM OF 6 FEET APART AND DRIVEN SECURELY INTO THE GROUND AT A MINIMUM OF 30 INCHES (WHERE PHYSICALLY POSSIBLE). 3. A TRENCH SHALL BE EXCAVATED APPROXIMATELY 8 INCHES WIDE AND 12 INCHES DEEP ALONG THE LINE OF POST AND UPSLOPE FROM THE BARRIER. THE TRENCH SHALL BE CONSTRUCTED TO FOLLOW THE CONTOUR. 4, WHEN SLIT FILM FILTER FABRIC IS USED, A WIRE MESH SUPPORT FENCE SHALL BE FASTENED SECURELY TO THE UPSLOPE SIDE OF THE POSTS USING HEAVY—DUTY WIRE STAPLES AT LEAST 1 INCH LONG, TIE WIRES OR HOG RINGS. THE WIRE SHALL EXTEND INTO THE TRENCH A MINIMUM OF 4 INCHES AND SHALL NOT EXTEND MORE THAN 36 INCHES ABOVE THE ORIGINAL GROUND SURFACE. g, SLIT FILM FILTER FABRIC SHALL BE WIRED TO THE FENCE, AND 20 INCHES OF THE FABRIC SHALL EXTEND INTO THE TRENCH. THE FABRIC SHALL NOT EXTEND MORE THAN 36 INCHES ABOVE. THE ORIGINAL GROUND SURFACE. FILTER FABRIC SHALL NOT BE STAPLED TO EXISTING TREES. OTHER TYPES OF FABRIC MAY BE STAPLED TO THE FENCE. 6. WHEN EXTRA —STRENGTH OR MONOFILAMENT FABRIC AND CLOSER POST SPACING ARE USED, THE WIRE MESH SUPPORT FENCE MAY BE ELIMINATED. IN SUCH A CASE, THE FILTER FABRIC IS STAPLED OR WIRED DIRECTLY TO THE POSTS WITH ALL OTHER PROVISIONS OF STANDARD NOTE "E" APPLYING. EXTRA CARE SHOULD BE USED WHEN JOINING OR OVERLAPPING THESE STIFFER FABRICS. 7. LOCAL GOVERNMENTS MAY SPECIFY THE USE OF PROPERLY COMPACTED NATIVE MATERIAL. IN MANY INSTANCES, THIS MAY BE THE PREFERRED ALTERNATIVE BECAUSE THE SOIL FORMS A MORE CONTINUOUS CONTACT WITH THE TRENCH BELOW, AND USE OF NATIVE MATERIALS CUTS DOWN ON THE NUMBER OF TRIPS THAT MUST BE MADE ON AND OFF —SITE. IF GRAVEL IS USED INSTEAD, THE TRENCH SHALL BE BACKFILLED WITH 3/4—INCH MINIMUM DIAMTER WASHED GRAVEL. CARE MUST BE TAKEN WHEN USING GRAVEL TO ENSURE GOOD CONTACT BETWEEN THE FABRIC AND THE TRENCH BOTTOM TO PREVENT UNDERCUTTING. g, FILTER FABRIC FENCES SHALL BE REMOVED WHEN THEY HAVE SERVED THEIR USEFUL PURPOSE, BUT NOT BEFORE THE UPSLOPE AREA HAS BEEN PERMANENTLY STABILIZED. RETAINED SEDIMENT MUST BE REMOVED AND PROPERLY DISPOSED OF, OR MULCHED AND SEEDED. 9. INSPECT IMMEDIATELY AFTER EACH RAINFALL, AND AT LEAST DAILY DURING PROLONGED RAINFALL. REPAIR AS NECESSARY. 10.SEDIMENT MUST BE REMOVED WHEN IT REACHES APPROXIMWATELY ONE THIRD THE HEIGHT OF THE FENCE, ESPECIALLY IF HEAVY RAINS ARE EXPECTED. 11. ANY SEDIMENT DEPOSITS REMAINING IN PLACE AFTER THE FILTER FENCE IS NO LONGER REQUIRED SHALL BE DRESSED TO CONFORM WITH THE EXISTING GRADE, PREPARED AND SEEDED. u \ z 410 �wrwer ■rarer w.wrwr ■rrwrr uow u a w c_;l a U m Y a < M M ,V) z w � Z w O U O � U U �— c w � U o U w C- W � wo U) o Q w zaaz O co 0 O I -GC rl I r , N W � U � w �` .. of 000 ;.� Z Q m Z O Q G'J 0� .J Z O V) Z wF-z _ d- Z Q CV C) LL1 3�: , w J U SHEET TITLE: T.E.S.C.
