877-833-6341 July 20, 2011 Mr. Grant Beck City of Yelm Community Development Department 105 Yelm Avenue West Yelm, WA 98597 Dear Mr. Beck: Thank you for the opportunity to comment on
the determination of nonsignificance for the Yelm Avenue Sidewalk Improvements project (SEPA No. 20110216) as proposed by Stephanie Ray, City of Yelm. The Department of Ecology (Ecology)
reviewed the environmental checklist and has the following comment(s): TOXICS CLEANUP: Amy Hargrove (360) 407-6262 If contamination is encountered during development or construction
activities, sampling must be conducted. If contamination is confirmed during testing, Ecology must be notified through the Environmental Report Tracking System Coordinator, Southwest
Regional Office at (360) 407-6300. SEPA REVIEWER: Sonia Mendoza WATER QUALITY CONTACT: Stephanie Jackso????^n (360) 407-6294 Any discharge of sediment-laden runoff or other pollutants
to waters of the state is in violation of Chapter 90.48 RCW, Water Pollution Control, and WAC 173-201A, Water Quality Standards for Surface Waters of the State of Washington, and is
subject to enforcement action. Erosion control measures must be in place prior to any clearing, grading, or construction. These control measures must be effective to prevent stormwater
runoff from carrying soil and other pollutants into surface water or storm drains that lead to waters of the state. Sand, silt, clay particles, and soil will damage aquatic habitat and
are considered to be pollutants. Proper disposal of construction debris must be on land in such a manner that debris cannot enter water of the state (e.g., Creeks) and stormdrains draining
to waters of the state or cause water quality degradation of state waters.
