The Department of Ecology (Ecology) reviewed the application notice and has [he following comment(s): TOXICS CLEANi7P: Lisa Pearson (360) 407-6261 If contamination is currently known or suspected during wns[tvc[ioq testing of the potentially contaminated media must be conducted. If contamination of soil or groundwater is readily visible, or is revealed by testing, Ecology must be notified. Contact the Environmental Report Tracking System Coordinator at the Southwest Regional Office at (360) 407fi300. For assistance and information about subsequent cleanup and to identify the type of testing that will be required contact Lisa Pearson. WATER QUALITY: Margaret Hill (360) 407-0246 Any discharge of sediment-laden runoff or other pollutants [o waters of [he state is in violation of Chapter 90.48 RC W, Water Pollution Control, and WAC 173-201 A, Water QualiTy Standards for Surface Waters of the State of Washington, and is subject [o enforcement action. Erosion control measures must be in place prior [o any clearing, grading, or construction. These wntrol measures must be effective to prevent s[otmwater runoff from carrying soil and other pollutants into surface water or storm drains that lead m waters of [he state. Sand, silt, clay particles, and soil will damage aquatic habitat and are wnsidered to be pollutants. Proper disposal of construction debris must be on land in such a manner that debris cannot enter s[ormdrains draining to waters of the state or cause water quality degradation of state waters. After completion of [his project, there is likelihood [hat s[ormwater runoff will contain increased levels of grease, oils, sediment, and other debris. It is recommended that stormwater treatment devices be inshalled so [ha[ any discharge will be appropriately treated to remove these substances. During cons[ructioq all releases of oils, hydraulic fluids, fuels, other petroleum products, paints, solvents, and other deleterious materials must be contained and removed in a manner that will prevent their discharge m waters and soils of [he state. The cleanup of spills should take precedence over other work on [he site. „,., C1 August 29, 2007 Page 2 Coverage under the National Pollution Discharge Elimination System (NPDES) and State Waste Discharge General Permit for Stormwater Discharges Associated with Construction Activities is required for construction sites which disturb an area of one acre or more and which have or will have a discharge of stormwa[er m surface water or a s[onn sewer. An application can be downloaded from Ecology's websi[e at http~// w acv wa eov/programs/wq/storm ate /construction/#Application or you can contact Charles Gilman at (360) 407-7451 for an application forth. Soil in stockpiles should be stabilized or protected with sediment-[rapping measures to prevent soil loss. All exposed areas of final grade or areas that are not scheduled for work, whether a[ final grade or otherwise, shall not remain exposed and un-worked for more than two days, between October 1 and April 30. Between May 1 and September 30, no soils shall remain exposed and un-worked for more than 7 days. Clearing limits and/or any easements or required buffers should be identified and marked in [he field, prior to the start of any clearing, grading, or constmction. Some suggested methods are staking and ^agging or high visibility fencing. A permanent vegetative cover should be established on denuded areas at final grade if they are not otherwise permanently stabilized. Properties adjacent to [he site of a land disturbance should be protected from sediment deposition through [he use of buffers or other perimeter controls, such as filter fence or sediment basins. All temporary erosion control systems should be designed to contain the runoff from the developed two year, 24-hour design storm without eroding. Provision should be made to minimize the tracking of sediment by constmction vehicles onto paved public roads. If sediment is deposited, it should be cleaned every day by shoveling or sweeping. Water cleaning should only be done after the area has been shoveled out or swept. Wash water from pain[ and wall finishing equipment should be disposed of in a way which will not adversely impact waters of the state. Untreated disposal of [his wastewater is a violation of State Water Quality laws and statutes and as such, would be subject to enforcement action. Ecology's comments are based upon information provided by the lead agency. As such, they do no[ constitute an exhaustive list of the various authorizations that must be obtained or legal requirements that must be fulfilled in order [o carry out the proposed action. If you have any questions or would like to respond to these comments please contact the appropriate reviewing staff listed above.
