Dear Ms. Merriman:
Thank you for the opportunity to comment on the mitigated determination of nonsignificance for
the Yelm Auto Recycling Project (20180242) located at 939 Northern Pacific Road in Yelm as
proposed by NPR Holdings, LLC. The Department of Ecology (Ecology) reviewed the
environmental checklist and has the following comment(s):
SOLID WASTE MANAGEMENT: Derek Rockett (360) 407-6287
All grading and filling of land must utilize only clean fill, i.e., dirt or gravel. All other
materials, including waste concrete and asphalt, are considered to be solid waste and permit
approval may be required from your local jurisdictional health department prior to filling
(WAC 173-350-990).
All removed debris and dredged material resulting from this project must be disposed of at an
approved site. Contact the local jurisdictional health department for proper management of
these materials.
TOXICS CLEANUP: Thomas Middleton (360) 407-7263
If contamination is suspected, discovered, or occurs during the proposed SEPA action,
testing of the potentially contaminated media must be conducted. If contamination of soil or
groundwater is readily apparent, or is revealed by testing, Ecology must be notified. Contact
the Environmental Report Tracking System Coordinator for the Southwest Regional Office
(SWRO) at (360) 407-6300. For assistance and information about subsequent cleanup and to
identify the type of testing that will be required, contact Thomas Middleton with the SWRO,
Toxics Cleanup Program at (360) 407-7263.

WATER QUALITY: Chris Montague-Breakwell (360) 407-6364
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 stormdrains that lead to waters of the state. Sand,
silt, clay particles, and soil will damage aquatic habitat and are considered to be pollutants.
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.
The following construction activities require coverage under the Construction Stormwater
General Permit:
1. Clearing, grading and/or excavation that results in the disturbance of one or more
acres and discharges stormwater to surface waters of the State; and
2. Clearing, grading and/or excavation on sites smaller than one acre that are part of a
larger common plan of development or sale, if the common plan of development or
sale will ultimately disturb one acre or more and discharge stormwater to surface
waters of the State.
a) This includes forest practices (including, but not limited to, class IV conversions)
that are part of a construction activity that will result in the disturbance of one or
more acres, and discharge to surface waters of the State; and
3. Any size construction activity discharging stormwater to waters of the State that
Ecology:
a) Determines to be a significant contributor of pollutants to waters of the State of
Washington.
b) Reasonably expects to cause a violation of any water quality standard.
If there are known soil/ground water contaminants present on-site, additional information
(including, but not limited to: temporary erosion and sediment control plans; stormwater
pollution prevention plan; list of known contaminants with concentrations and depths found;
a site map depicting the sample location(s); and additional studies/reports regarding
contaminant(s)) will be required to be submitted.
You may apply online or obtain an application 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 from
construction activities and must submit it on or before the date of the first public notice.
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.
