Dear Ms. Merci~nan:
Thank you for the opportunity [o comment on the revised notice of application for the Willow Glenn
Phase III Preliminary Plat project (Case No. SUB-OS-0345-YL) located on Grove Road Southeast as
proposed by Yelm Property Development, LLC. The Department of Ecology (Ecology) reviewed the
environmental checklist and has the following wmment(s):
WATER QUALITY: Margaret Hill (360) 407-0246
Any discharge of sediment-laden runoff or other pollutants to waters of the state is in violation of
Chapter 90.48, Water Pollution Control, and W AC 173-201 A, Water Quality Standards Cor Surface
Waters of the State of Washington, and is subject to enforcement action.
Erosion control measures must be in place prior to airy 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 the
natural stormwater drainage system or cause water quality degradation of state waters.
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.
Source control best management practices such as plastic covering mulch, temporary seeding, and
phased clearing (for example) should be used Io control erosion during construction. More examples
of effective source control Best Management Practices can be found in Ecology's two stormwater
management manuals, Smrmwaler Managentettt Manual far Puget Sound (/992) and stormwater
Management Manual for Western Washingmn (200/).
Coverage under the National Pollution Discharge Elimination system (NPDES) and State Waste
Discharge General Permit Cor stormwater Discharges Associated with Construction Activities is
required for construction sites which disturb an area of one acre or more and which have or wit l have
a discharge of stormwater to surface water or a storm sewer An application can be downloaded from
