Dear Mc Bcck:
Thank you for the opportunity [o comment on [he mitigated determination of nonsignificance for the
Yelm Properties Hutch Development Subdivision, located at 9306 ML View Road Southeast Yelm as
proposed by Yelm Property Development, LLC. The Department of Ecology (Bcology) reviewed the
environmental checklist and has the following comment(s):
AIR QUALITY: Bernard Brady (3fi0) 407-6803
Best Management Practice far minimization of [rack out and windblown dust should be required
in applicable permitting.
TOXIC CLEANUP: Lisa Pearean (360) 407-6267
If contamination is currently known or suspected during wns[me[ion, Ics[ing 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 [he Environmental Report
Tracking System Coordinator at the Southwest Regional Office at (360) 407-6300. For assistanw
and information about subsequent cleanup and to identity the type of testing that wit l be required
contact Mr. Bob Warren with the Toxic Cleanup Program a[ [hc Southwest Regional Office.
WATER QUALITY: Margaret Hill (360) 407-0246
Any discharge of sediment-laden runoff or other pot lutants to waters of the state is in violation of
Chapter 90.48 RCW, Water Pollution Control, and WAC 173-201 A, 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 t}om 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 [o be pollutants.
Proper disposal of construction debris must be on land in such a manner that debris cannot enter
the natural stormwater drainage systems or cause water quality degradation of state waters.

During cons[mctioq all releases of oils, hydraulic fluids, fuels, other petroleum products, paints,
solvents, and other deleterious materials must be wntained and removed in a manner that will
prevent their discharge [o waters and soils of the state. The cleanup of spills should take
precedence over other work on the site.
Coverage under [he National Pollution Discharge Elimination System (NPDES) and State Waste
Discharge General Permit for Stormwater Discharges Associated with Constmction Aotivities is
required for construction sites which disturb an area of one acre or more and which have or will
have a discharge of stormwater to surface water or a storm sewer. An application can be
downloaded from Ecology's websi[e at
htto'// ecv wa env/rrroerams/ o/stormwater/cons[mction/#Appl'ca['on or you can contact
Charles Gilman at (360) 407-7451 for an applioa[ion form.
Soil in stockpiles should be stabilized or protected with sediment-trapping measures to prevent
soil loss. All exposed areas of final grade or areas [ha[ are not scheduled for work, whether at
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 3Q no soils shall remain
exposed and un-worked for more than 7 days.
A permanent vegetative cover should be established on denuded areas a[ fmal 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.
Provision should be made to minimize the [racking of sediment by cons[mc[ion vehioles onto
paved public roads. If sediment is deposited, i[ should be cleaned every day by shoveling or
sweeping. W ater cleaning should only be done after the area has been shoveled out or swept.
Ecology's comments are based upon the information provided with [he SEPA checklist. As such, they do
no[ constitute an exhaustive list of [he 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 [o respond [o these comments please contact the appropriate
reviewing staff listed above.
