Dear Ms. Merriman:
Thank you for [he opportunity [o comment on the notice of application for [he Today's Dental Demolition
and New Construction project (Case No. SPR-07-0136-YL) located at 502 Yelm Avenue West as
proposed by BCRA. The Department of Ewlogy (Ecology) reviewed the application notice and has the
following comment(s):
TOXICS CLEANUP: Lisa Pearson (360) 407-6261
If contamination is currently known or suspected during construction, testing of the potentially
conmminated media must be conducted. [f 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 [he Southwest Regional Office at (360) 407-6300. For assistance and information
about subsequent cleanup and to identify the type of testing that will be required contact Mr. Bob
Warren with the Toxics Cleanup Program at (360) 407fi361.
WATER QUALITY: Margaret Aill (360) 407-0246
The project called `Today's Dental' may require coverage under a Construction S[otmwa[er National
Pollution Discharge Elimination System (NPDES) permit This permit is regnired if your project will
disturb one acre or more of soil surface area and [here is discharge of stortnwa[er off the site (streams
and roadside ditches or stormdrains that discharge to streams) before or during constmetion. The
permit application form, called a Notice of Intent, is available on Ecology's website at:
httn~//www acv.wa.eov/oroermns/wq/stormwater/construction/#Annlication.
Any discharge of sediment-laden mnoff or other pollutants 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 Washingto^, 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 stormwa[er runoff from carrying soil and other
pollutants into surface water or storm drains that lead to waters of [he 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
waters of the state or cause water quality degradation of state waters.

During construction, all releases of oils, hydraulic fluids, fuels, other petroleum products, paints,
solvents, and other deleterious materials most be contained and removed in a manner that will prevent
[heir discharge [o waters and soils of the state. The cleanup of spills should take precedence over
other work on the site.
Soil in stockpiles should be stabilized or protected with sediment-trapping measures to prevent soil
loss. All exposed areas of final grade or areas that are no[ scheduled for work, whether at final grade
or otherwise, shall not remain exposed and un-worked for more than two days, between October I
and April 30. Between May 1 and September 3Q, no soils shall remain exposed and un-worked for
more than 7 days.
Clearing limits and/or any easements or required buffers should be identified and marked in the Feld,
prior to [he start of any clearing, grading, or construction. Some suggested methods are staking and
flagging or high visibility fencing.
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 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 [he area has been shoveled out or swept.
Ecology's comments are bused upon the information provided with the SEPA checklist. As such, [hey do
not constitute an exhaustive list of the various authorisations that must be obtained or legal requirements
[hat must be fulfilled in order [o carry out the proposed action.
If you have any questions or would like to respond to these comments please contact the appropriate
reviewing staff listed above.
