Business inspections

Stormwater inspections protect Puget Sound

Everyday activities at your business can cause pollution. Our team helps businesses prevent spills and comply with regulations.

We visit businesses that typically store chemicals on-site, like auto repair shops, manufacturing facilities, and car and pet washing services. We also visit businesses with outdoor operations or whose practices could impact stormwater, like restaurants, apartments, and health providers.

Businesses are responsible for preventing pollution

Stormwater drains from your business into a nearby stream or river. If there is any litter or pollution on the ground at your business, stormwater will carry it to Puget Sound. 

Toxic chemicals can harm fish and wildlife, even if they are labeled ‘biodegradable.’

It is your business’ responsibility to keep pollution out of the storm drain. Avoid expensive clean-ups — don’t let dirty water into storm drains.

Common activities like washing cars, pressure washing, and rinsing mats can produce dirty washwater. Washwater is not allowed in the stormwater system because it contains oil, soap, grease, heavy metals, and other chemicals.

  2. Use less toxic cleaning products
