EPA Draft MS4 Permit Comment DUE DATE

The Ohio Stormwater Association (OSWA) has coordinated with Ohio EPA during early stakeholder outreach and permit development activities over the course of the past year. On July 15, 2020, Ohio EPA submitted a public notice that the draft Small MS4 permit was available for comment until September 8, 2020. The current Small MS4 permit expired on September 10, 2019, but permittees are still held to permit requirements until a new permit is issued. A new Small MS4 permit is typically issued once every five years. The Small MS4 permit can drive the bulk of many municipal stormwater programs, setting required activities and performance standards.
