Mullet, Mayor Department of Community Development Steve Lancaster, Director June 29, 2004 Teresa Eturaspe, SEPA Coordinator Department of Fish and Wildlife 600 Capital Way North Olympia, WA 98501 Subject: IGE Retention Pond Sediment Clean Out and Stream Restoration Dear Teresa: The City of Tukwila received the enclosed SEPA checklist for the project listed above. Upon review, I see that the City will require no permits for the work. The State of Washington has rules that determine who is the lead agency for SEPA. Specifically, WAC 197 -11 -924 Determining the Lead agency and WAC 197 -11 -930 Lead Agency for private projects with one agency with jurisdiction provide direction on SEPA jurisdiction. The lead agency means the agency with the main responsibility for complying with SEPA's procedural requirements. For private projects the lead agency is the agency with jurisdiction. An agency with jurisdiction means an agency with authority to approve all or part of a nonexempt proposal. The primary permit listed for government approval is a Hydraulic Permit, which is reviewed and issued by the Department of Fish and Wildlife. The City of Tukwila has determined that the Washington State Department of Fisheries is the lead agency. Per WAC 197 -11- 924(2) I am forwarding the information to you. No other agency with jurisdiction has been identified on the Checklist. If you have any questions about this decision, please call me at 206 431 -3651 or email me at mbradshaw @ci.tukwila.wa.us.

Agency requesting checklist: City of Tukwila. 6. Proposed timing or schedule (including phasing, if applicable): The project will be completed in 2004 7. Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? If yes, explain. No 8. List any environmental information you, know about that has been prepared, or will be prepared, directly related to this proposal. A J.A.R.P.A form will be pending the determination of this SEPA to apply for a Hydraulic Project Approval from the Washington Department of Fish, and Wildlife. Page 1 ENVIRONMENTAL CHECIPLIST 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. None Known 10. List any government approvals or permits that will be needed for your proposal. HPA from WDFW 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. Section E requires a complete description of the objectives and alternates of your proposal and should not be summarized here. The project is to maintain an existing sediment detection structure located within Riverton Creek. Currently, the sediment detention structure built by Boeing in 1997 is in need of maintenance. The purpose of this structure is to limit the passage of sand and silt from reaching the newly restored salmon habitat. In addition, this structure serves to prevent the increase in elevation of the stream bed which has in the past been prone to localized flooding. The maintenance on this will be performed every 1 to 3 years depending upon sediment build up. Due to the increased sediment in the stream bed, sand and silt will need to be removed from other locations on the property noted on the location maps. 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 project is located in the City of Tukwila on _ See Attached Location Map 13. Does the proposal lie within an area designated on the City's Comprehensive Land Use Policy Plan Map as environmentally sensitive? Yes Page 2 • • ENVIRONMENTAL CHECKLIST B. ENVIRONMENTAL ELEMENTS 1.

The checklist includes a series of "Yes" or "No" questions about your project, organized into four parts. Starting with Part A on Page 1, read each question carefully, circle "Yes" or "No," and proceed to the next question as directed by the checklist. To answer these questions, you may need to refer to site plans, grading and drainage plans, critical areas studies, or other documents you have prepared for your project. The City will evaluate your responses to determine if "take" is indicated. Part A: Please review and answer each question carefully. Consider all phases of your project including, but not limited to, construction, normal operation, potential emergency operation, and ongoing and scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 1 -0 Will the project require any form of grading? Grading is defined as any excavating, filling, clearing, or creation of impervious surface, or any combination thereof, which alters the existing ground surface of the earth (see Tukwila Municipal Code (TMC) Chapter 18.06, Zoning Code, Page 18 -11). Please circle appropriate response. NO - Continue to Question 2 -0 Continue to Question 1 -1 (Page 3) 2 -0 Will the project require any form of clearing? Clearing means the removal or causing to be removed, through either direct or indirect actions, any vegetation from a site (see Chapter 18.06, Page 18 -8). Please circle appropriate response. NO - Continue to Question 3 -0 Continue to Question 2 -1 (Page 4) 3 -0 Will the project require work, during any time of the project, below the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers or in wetlands? Ordinary high water mark is the mark that is found by examining the bed and banks of a stream and ascertaining where the presence and action of waters are so common and usual as to distinctly mark the soil from that of the abutting upland, in respect to vegetation (see TMC Chapter 18.06, Page 18 -15). Please circle appropriate response. NO - Continue to Question 4 -0 - S2 Continue to Question 3 -1 (Page 5) 4 -0 Will the project result in the processing or handling, storage, or treatment of hazardous substances? This does not include the proper use of fuel stored in a vehicle's fuel tank. Hazardous substances are any liquid, solid, gas, or sludge, including any material, substance, product, commodity, or waste, regardless of quantity, that exhibits the characteristics or criteria of hazardous waste as defined by Washington Administrative Code 173 -303 (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18 -11). This includes fuel or other chemicals stored on -site during construction. Please circle appropriate response. NO Continue to Question 5 -0 YES - Continue to Question 5 -0 5 -0 Will the project result in the withdrawal, injection, or interception of groundwater? Examples of projects that may affect groundwater include, but are not limited to: construction of a new well, change in water withdrawals from an existing well, projects involving prolonged construction dewatering, projects installing French drains or interceptor trenches, and sewer lines. For the purpose of this analysis, projects that require a geotechnical report pursuant to the requirements of TMC 18.45.060 and 18.45.080E.4, or would require a geotechnical report if not exempt under TMC 18.45.080A, should answer Yes. Please circle appropriate response.

This does not include the one -time use of transplant fertilizers. Landscaping means natural vegetation such as trees, shrubs, groundcover, and other landscape materials arranged in a manner to produce an aesthetic effect appropriate for the use of the land (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18- 13). For the purpose of this analysis, this includes the establishment of new lawn or grass. P1 se circle appropriate response. Checklist Complete- YES — Checklist Complete Part B: Please answer each question below for projects that include grading. Review each question carefully, considering all phases of your project including, but not limited to construction, normal operation, potential emergency operation, and ongoing and scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 1 -1 Will the project involve the modification of a watercourse bank or bank of the Green/Duwamish or Black Rivers between the ordinary high water mark and top of bank? This includes any projects that will require grading on any slope leading to a river or stream, but will not require work below the ordinary high water mark. Work below the ordinary high water mark is covered in Part C. Please circle appropriate response. N(Q. Continue to Question 1 -2 Continue to Question 1 -2 1 -2 Could the construction, operation, or maintenance of the project result in sediment transport off site or increased rates of erosion and /or sedimentation in watercourses, the Green/Duwamish rivers, or the Black River? Most projects that involve grading have the potential to result in increased erosion and/or sedimentation as a result of disturbances to the soil or earth. If your project involves grading and you have not prepared a Temporary Erosion and Sedimentation Control Plan specifically designed to retain 100 percent of the runoff (including during construction) from impervious surface or disturbed soils, answer Yes to this question. If your project is normally exempt under the Tukwila Municipal Code and would not require the preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in erosion or sediment transport off site or beyond the work area, answer Yes to this question. Please circle appropriate response. NO - Continue to Question 1 -3 Continue to Question 1 -3 1-3 Will the project result in the construction of new impervious surfaces? Impervious surfaces include those hard surfaces which prevent or restrict the entry of water into the soil in the manner that such water entered the soils under natural conditions prior to development; or a hard surface area that causes water to run off the surface in greater quantity or at an increased rate of flow from the flow presented under natural conditions prior to development (see TMC Chapter 1$.06, Tukwila Zoning Code, Page 18 -12). Such areas include, but are not limited to, rooftops, asphalt or concrete paving, compacted surfaces, or other surfaces that similarly affect the natural infiltration or runoff patterns existing prior to development.
