Ohio EPA recently issued the renewal of the Industrial Stormwater General Permit OHR000007 (also known as the Multi-Sector General Permit), with an effective date of June 1, 2022. Facilities with existing coverage under the previous version of the permit (OHR000006) are required to submit a new Notice of Intent (NOI) application within 90 days of the effective date of the permit.
As has been required in previous generations of the permit, a Stormwater Pollution Prevention Plan (SWPPP) is required to be maintained at each facility that obtains coverage under the General Permit. The renewed permit has some new requirements, including identifying TMDLs in the watershed.

Industrial Stormwater Permit – Do I need one?
Industrial facilities that fall in a regulated sector, defined by certain Standard Industrial Classification (SIC) codes listed in Appendix D of the permit, are required to have an industrial stormwater permit (either via the General Permit or an individual permit). Wastewater treatment facilities with a design flow of 1 MGD or more and Closed Landfills are also included in this general permit.
Stormwater runoff monitoring required in the General Permit includes quarterly visual assessments (including a snowmelt assessment) for ALL facilities and four quarters of “Benchmark” monitoring over the course of the first two years of the permit for some facilities.
B&N Can Help!
Burgess & Niple can assist with the NOI application, preparing the SWPPP in accordance with the Permit, and preparing for and conducting the required stormwater monitoring. If all industrial activities are under cover at your facility, we can assist you with a No Exposure Certification application to exempt your facility from the General Stormwater Permit requirements.
