SUBJECT: Public Works Shops Decant Facility Project
Department of Ecology Grant Application

ISSUE
Authorize the submittal of a Department of Ecology (DOE) Water Quality Combined Funding
Program grant for an enhanced maintenance plan (EMP) and a decant facility at the combined
Public Works Shops site.
BACKGROUND
As part of the 2016 plan developed for the Public Works Shops projects, a decant facility was
identified as a potential improvement to the future site. A decant facility is an area where
stormwater, gathered by vactor trucks from catch basins and other stormwater catchment areas,
can be properly disposed of. Stormwater typically contains high concentrations of contaminants.
Currently, the City relies solely on a King County (KC) decant facility to dispose of their vactor
waste from catch basin cleaning. The KC decant facility is located in Renton, WA which is
approximately 18 miles roundtrip during peak traffic. Furthermore, since the pandemic KC has
reduced their hours of operation to just three days from previously five days. Also, with the
reduced hours it is often busier and there is often a line. Their hours of operation and driving
distance severely limit the City on the frequency and number of catch basins they can clean
along with additional costs.
DISCUSSION
DOE has issued a call for projects inviting applicants to submit projects for the Water Quality
Combined Funding Program grant. The Water Quality Combined Funding Program grant funds
projects that improve and protect water quality throughout the state. Grant applications are due
on October 12, 2022. If received, grant funding would be available to the City starting in July
2023.
A new requirement to receive DOE funding for maintenance projects, which includes decant
facilities, is the development of an Enhanced Maintenance and Source Control Plan (EMP). An
EMP is a tool that provides information on total stormwater quality infrastructure and
performance costs, and helps local governments prioritize resources based on areas that pose
the biggest potential risk to water quality. The City can apply for funding for an EMP as part of
the grant application for the decant facility, with the condition that the City completes the EMP
before starting design on of decant facility.
FINANCIAL IMPACT
This grant would fund the development of an EMP and the design phase of the decant facility.
It is estimated that an EMP will cost approximately $100,000 and that the design for the decant
facility will cost $450,000; totaling $550,000. The City is requesting $467,500 from DOE's Water
Quality Combined Funding Program grant. This grant requires a 15% match, which is $82,500
for this project. Project match would come from the Surface Water enterprise fund.
