Dear Ms. Barlow:
Thank you for the opportunity to comment on the Scope of an Environmental Impact Statement
regarding the modification to establish five housing zones-Estate, Single Family, Cottage,
Multifamily and Mixed Use, and Neighborhood Commercial; create 30 acres of greenspace with
trails, a 10-acre park and wildlife travel corridor (Proponent: Black Realty, Inc.). The
Department of Ecology (Ecology) has reviewed the documents and submits the following
comments:
Water Quality Program – Shannon Adams (509) 329-3610
You must register all new dry wells and other injection wells with the Underground
Injection Control program (UIC) at Department of Ecology prior to use. In addition,
discharge from the well(s) must comply with the ground water quality requirement
(nonendangerment standard) at the top of the ground water table. Contact the Eastern
Regional Office UIC Coordinator, Llyn Doremus at (509) 329-3518 or via email at
Llyn.Doremus@ecy.wa.gov. You may also go to https://ecology.wa.gov/Regulations-
Permits/Guidance-technical-assistance/Underground-injection-control-program for
registration forms and further information.
A Stormwater Pollution Prevention Plan for the project site may be required and should
be developed by a qualified person(s). Erosion and sediment control measures in the plan
must be implemented prior to any clearing, grading, or construction. These control
measures must be effective to prevent soil from being carried into surface water by
stormwater runoff. Sand, silt, and soil can damage aquatic habitat and are considered
pollutants. The plan must be upgraded as necessary during the construction period.

Proper disposal of construction debris must be in such a manner that debris cannot enter
the natural stormwater drainage system or cause water quality degradation of surface
waters. Dumpsters and refuse collection containers shall be durable, corrosion resistant,
nonabsorbent, nonleaking, and have close fitting covers. If spillage or leakage does
occur, the waste shall be picked up immediately and returned to the container and the
area properly cleaned.
The operator of a construction site that disturbs one acre or more of total land area, and
which has or will have a discharge of stormwater to a surface water or to a storm sewer,
must apply for coverage under Department of Ecology’s Baseline General Permit for
Stormwater Discharges Associated with Construction Activities.
Owners of sites where less than one acre of total land area will be disturbed must also
apply if the construction activity is part of a larger plan of development or sale in which
more than one acre will eventually be disturbed. Discharge of stormwater from such
sites without a permit is illegal and may be subject to enforcement action by the
Department of Ecology.
If any soil or ground water contamination is known to be on the site, additional
information is needed. The applicant may be required to submit additional studies and
reports including, but not limited to, temporary erosion and sediment control plans, a
stormwater pollution prevention plan, a site map depicting sample locations, a list of
known contaminants with concentrations and depths found and other information about
the contaminants.
Application should be made at least 60 days prior to commencement of construction
activities. A permit application and related documents are available online at
https://ecology.wa.gov/Regulations-Permits/Permits-certifications/Stormwater-general-
permits/Construction-stormwater-permit, or by contacting the Water Quality program,
