Thank you far the opporiunity to comment on the mitigated determination of nonsignificance for the
Mountain Meadows Preliminary Plat project (SEPA No. OS-0121) located on the east side of Burnett
Road, north of Yelm Avenue West (SR-510) as proposed by Heririetta Morey. We reviewed the
environmental checklist and have the following comments:
WATER QUALITY: Margaret Hill (360) 407-0246
Erosion~control measures must be in place prior to any clearing, grading, ar 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 ana are considered to be pollutants.
Any discharge of sediment-laden runoff or other pollutants to waters of the state'i's in violation of Chapter
90.48, Water Pollution Control, and WAC 173-201A, Water Quality Standards for Surface Waters of the
State of Washington, and is subject to enforcement action.
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
Qn the site.
Coverage under the National Pollution Discharge Elimination system (NPDES) and State Waste
Discharge General P,ermit for Stormwater Discharges Associated with Construction Activities is required
for construction sites which disturb an area of five acres or more and which have or will have a discharge
of stormwater to surface water or a storm sewer.
