877-833-6341 April 22, 2011 Ms. Tami Merriman City of Yelm Community Development Department 105 Yelm Avenue West Yelm, WA 98597 Dear Ms. Merriman: Thank you for the opportunity to comment
on the notice of application for the Yelm Daycare Center project (Land Use Case No. 20110166) located on Tahoma Boulevard and Berry Valley Road intersection as proposed by Allen and
Marijke Deutscher. The Department of Ecology (Ecology) reviewed the information provided and has the following comment(s): TOXICS CLEANUP: Mohsen Kourehdar (360) 407-6256 If contamination
is suspected or discovered during development or construction activities, sampling must be conducted. If contamination is confirmed during testing, Ecology must be notified. Contact
the Environmental Report Tracking System Coordinator at Ecology’s Southwest Regional Office at (360) ?????360) 407-6300. For assistance and information about subsequent cleanup and
to identify the type of testing that will be required, contact Mohsen Kourehdar at the phone number given above. SEPA REVIEWER: Sonia Mendoza WATER QUALITY CONTACT: Bruce Barbour (360)
407-6554 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. During construction, 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 to waters and soils of the state. The cleanup of spills
should take precedence over other work on the site.
April 22, 2011 Page 2 Clearing limits and/or any easements or required buffers should be identified and marked in the field, prior to the start of any clearing, grading, or construction.
Some suggested methods are staking and flagging 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 the site of a land disturbance should be protected from sediment deposition through the 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 construction 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 paint and wall finishing equipment should be disposed of in a way which
will not adversely impact waters of the state. Untreated disposal of this wastewater is a violation of State Water Quality laws and statutes and, as such, would be subject to enforcement
action. This project may require a construction stormwater permit (also known as National Pollution Discharge Elimination System (NPDES) and State Waste Discharge General Permit for
Stormwater Discharges Associated with Construction). This permit is required for projects which meet both of the following conditions: 1. One or more acres of soil surface area will
be disturbed by construction activities. 2. The site already has offsite discharge to waters of the state or storm drains or will have offsite discharge during construction. An application
with instructions can be downloaded from Ecology's website at: http://www.ecy.wa.gov/programs/wq/stormwater/construction/-Application. Construction site operators must apply for a permit
at least 60 days prior to discharging stormwater. Ecology’s comments are based upon information provided by the lead agency. As such, they may not constitute an exhaustive list of the
various authorizations that must be obtained or legal requirements that must be fulfilled in order to 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. Department of Ecology Southwest Regional Office (SM:Yelm Daycare Center) cc: Bruce Barbour, WQ Josh Klimek,
