How do I know if I need a Department of Ecology (also known as Ecology or DOE) Industrial Stormwater General Permit (ISPG)?

If your facility conducts industrial activities that discharge stormwater to a surface water body or to a storm sewer system, then it may require Coverage under a Washington State Department of Ecology (Ecology) Industrial Stormwater General Permit (ISGP).

  • Contact Ecology at (360) 407-7451 for information and to obtain a permit application form (called “Notice of Intent” or “NOI”) or download application forms here.
  • A list of the covered industrial activities is included in Table 1 of the permit available here.
  • For more Information about the ISGP requirements, refer to the Frequently Asked Questions fact sheet here.

Please note:

  • City approval does not release the applicant from state or other permitting requirements.
  • New facilities (beginning operations after January 1, 2010) seeking permit coverage and existing facilities seeking modification of permit coverage are subject to public notice requirements, including a 30-day public comment period. Applicants must publish a public notice at least once a week for two consecutive weeks (with seven days between the two publications) in a single newspaper of general circulation in the county where the facility is located.
  • Ecology cannot grant or modify permit coverage earlier than the end of the 30-day public comment period which begins on the date of the second public notice.
