Putpose 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 enviromnental 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
"proposer," and "affected geographic area," respectively.
