h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: A stormwater pollution prevention plan (SWPPP) will be prepared in accordance with the Washington State Dept. of Ecology's NPDES permit requirements. Approved erosion mitigation measures will be implemented prior to and during construction. The erosion control plan will include filter fabric fencing, a construction entrance, temporary swales and sediment ponds, and the employment of Best Management Practices during construction. The NPDES permit will be secured through the Washington State Dept. of Ecology prior to construction. 2. Air a. What types of emissions to the air would result from the proposal during construction, - operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. Construction vehicles and equipment will result in increased emissions and dust into the air. After project completion, emissions to the air will be limited to the vehicle exhaust generated by employees and customers of the retail development. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. No. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Site will be sprinkled with water during dry construction months as necessary to control dust. Construction vehicles are typically equipped with factory -installed mufflers and spark arresters that will control excessive emissions. 3. Water a. Surface Water: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. There are four small wetlands on site, two Category I/ and two Category Ill. Wetlands A, B and C are located in the southeast corner of the site and Wetland D is located in the central portion of the site. Two streams are located near the site. Japanese Gulch Creek, a Type F stream, is located off -site to the west. Edgewater Creek, a Type FIN stream, is located off -site to the northwest. Both of these streams flow to Puget Sound, which is located approximately 2,000 feet north of the site. SEPA Environmental checklist (WAC 197-11-960) May 2014 Page 5 of 16
