General Storm Water NPDES Permit for Industrial Activity

Permit Renewal Notification: The General NPDES Permit for Industrial Activity was renewed on July 1, 2023. Part D. Paragraph 7.b. of the permit (Duty to Reapply) requires permittees to submit an NOI for renewal no later than 150 days after the new General Permit is issued. Permit Renewal does not require a fee. 

Eleven Categories of Storm Water Discharges Associated with Industrial Activity were regulated under Phase I of the NPDES Storm Water Program in 1990.

No Exposure Exclusion for regulated categories of Industrial Activities

Under the Phase II Rule, no new categories of industrial activity are designated into the storm water program. The Rule does, however, include a revised "No Exposure Exclusion" that is available to all regulated categories of industrial activity (except category (x) - large construction activity) if the facility operator can certify that industrial activities are not exposed to storm water runoff.
