Ohio EPA Issues Draft Renewal of the Ohio Industrial Stormwater General Permit Requirements

The Ohio EPA recently issued a draft renewal of the Industrial Storm Water General Permit. The public notice was released on December 13, 2021 and comments are due February 3, 2022. Once the permit is finalized, facilities with existing coverage under the previous version of the permit (OHR000006) will be required to submit a new Notice of Intent (NOI) form within 90 days of issuance of the renewed permit.

As has been required in previous generations of the permit, a Storm Water Pollution Prevention Plan (SWPPP) is required to be maintained at each facility that obtains coverage under the General Permit. The draft permit also has some new requirements, including identifying TMDLs in the watershed.

Industrial Storm Water Permit – Do I need one?

Only industrial facilities that fall in a regulated sector, defined by Standard Industrial Classification (SIC) codes are required to have an industrial storm water permit (either via the General Permit or an individual permit). Wastewater treatment facilities with a design flow of 1 MGD or more are included in this general permit.

The storm water runoff monitoring required in the General Permit includes quarterly visual assessments (including a snowmelt assessment) and 4 quarters of “Benchmark” monitoring over the course of the first 2 years of the permit.
