Business Inspections for Pollution Prevention & Source Control Requirements

What is Pollution Source Control?

Spills or improperly stored waste can get carried to streams when it rains.  This pollutes rainwater.  Polluted rainwater can harm local streams and Puget Sound.  Pollution Source Control are business practices that keep pollution out of rainwater.    Staff training or covering waste bins are examples of Source Control.  These are called Source Control Best Management Practices.  Other examples of common pollutants and associated best practices include:

What Types of Businesses Qualify?

Certain business types will need to have plans to keep pollutants out of rainwater.  These include a wide variety of business types and commercial entities that:

If you received a postcard in the mail about Pollution Prevention for Businesses it means your business likely qualifies. This is the case even if you have other environmental permits. Business types that qualify for the Source Control Program include, among others:

  • dry cleaners
  • auto and equipment repair, auto detail, auto body
  • gasoline stations
  • restaurants, cafes, bars, food trucks
  • veterinarians and pet shops
  • dentists and medical laboratories
  • manufacturers and fabricators
  • institutions and municipal sites
  • properties that border water bodies
  • mobile businesses

An example list of qualifying business types by industrial classification code can be found in Appendix 8 of the NPDES Permit.

Free Technical Assistance

No action is needed by businesses at this time. The City will reach out to qualifying businesses, and follow-up communications will be provided as the Source Control Program gets started.

Starting in 2023, the City will provide free technical assistance to businesses that have the potential to cause stormwater pollution, even in small amounts. The technical assistance will be provided through inspections at qualifying businesses and advising them on the use of best management practices (BMPs) for managing stormwater runoff.

Why We Have this Program

The Washington State Department of Ecology, through the City’s NPDES Permit, requires Mukilteo and other jurisdictions to have a Source Control Program, beginning in 2023. The goal is to keep pollution out of rainwater.

Anticipated Timeline for Program and Code Adoption

  • February 2022: announce program to potentially qualifying businesses via postcard and webpage – Complete
  • April 2022: send second postcards to qualifying businesses with schedule
  • May 16, 2022: public hearing and ordinance adoption; 6:00pm at City Hall.  Public is welcome.

  • By January 2023: begin business inspections and technical assistance

Opportunities for Involvement

The City anticipates that a hearing on the adoption of revised municipal code update will be May 16, 2022. The City will provide the opportunity for public comment during this process. In addition to posting legally required notices, the City will send postcards to qualifying business and update this website.
