Dear Mr. Beck:
Thank you for [he opportunity to comment on the mitigated determination of nonsignificance for the
Yelm RV/Boat and Mini-Storage project (SEPA No. 07-0276) located on Rho[on Road Southeast as
proposed by Randy Weber. The Department of Ecology (Ecology) reviewed the environmental checklist
and has the following wmment(s):
SHORELANDS: Sarah Lukas (360) 407-7459
If any part of [he proposed development is within 200-fee[ of Yelm Creek the entire project will be
subject to the City of Yelm's Shoreline Master Program and must be consistent with [he applicable
regulations.
TOXICS CLEANUP: Lisa Pearson (360) 407-6261
If contamination is currently known or suspected during constmctioq testing of the potentially
contaminated media must be conducted. If contamination of soil or groundwater is readily visible, or
is revealed by testing, Ewlogy must be notified. Contact the Environmental Report Tracking System
Coordinator at the Southwest Regional Office a[ (360) 407-6300. For assistance and information
about subsequent cleanup and to identify the type of testing that will be required, please contact Lisa
Pearson.
WATER QUALITY: Margaret Hill (360) 407-0246
Any discharge of sediment-laden runoff or other pollumnts to waters of the 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 to enforcement action.
Erosion control measures must be in place prior to any clearing, grading, or construction. These
wntrol measures must be effective to prevent s[ormwa[er 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 [ha[ debris cannot enter Yelm
Creek and its buffers or cause water quality degradation of state waters.
During constmctioq 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.

Clearing limits and/or any easements or required buffers should be identified and marked in [he field,
prior [o the start of any clearing, grading, or construction. Some suggested methods are staking and
Flagging or high visibility fencing.
Soil in stockpiles should be stabilized or protected with sediment-trapping measures to prevent soil
loss. All exposed areas of final grade or areas [hat 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 l
and April 30. Between May I 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 at final grade if they are not
otherwise permanently stabilized.
Cm and/or fill slopes should be designed to minimize erosion. Methods such as slope roughening,
terraces, or pipe slope drains may be used.
All temporary erosion control systems should be designed to contain [he runoff from [he developed
two year, 2A-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, i[ should be cleaned every day by shoveling or sweeping.
Water cleaning should only be done a$er 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 [his wastewater is a violation of Stale
Water Quality laws and statutes and as such, would be subject to enforcement action.
This site has offsi[e discharge now when stormwater drains into Yelm Creek or into s[ormdrains
along Crystal Springs Road Northwest. Construction activities will disturb one or more acres of soil
surface area. Therefore, this project will need a Construction Stormwater National Pollution
Discharge Elimination System (NPDES) permit. The permit application forth is available on
Ecology's website at: http~//www ecv a eov/oroerams/ q/storm ater/construction/#Appl'ca['o .
To avoid project delays, applicants are encouraged to submit completed forms and [o publish public
notices more than 60 days before [he planned start of the project.
Ecology's comments are based upon information provided by [he lead agency. As such, [hey do not
constiN[e an exhaustive list of the various authorizations that must be obtained or legal requirements that
must be fulfilled in order to cant' out [he proposed action.
If you have any questions or would like [o respond to these comments please contact [he appropriate
reviewing staff listed above.
