Ohio EPA Issues Final Version of the Ohio Construction Stormwater General Permit

Ohio EPA recently issued the final version of the Construction Stormwater General Permit OHC000006. The permit authorizes stormwater discharges from construction activity disturbing one or more acres and is applicable statewide. The permit also authorizes some discharges that are not entirely considered construction stormwater (such as trench dewatering), as well as stormwater discharges associated with on-site concrete and asphalt batch plants. The permit became effective on April 23, 2023, and expires on April 22, 2028.

Existing permittees having coverage under the previous generation of this general permit (OHC000005) will have continuing coverage under OHC000006 with the submittal of a timely renewal application through the Ohio EPA eBusiness Center portal. Within 180 days from the effective date of this permit, existing permittees must submit a completed renewal application expressing their intent for continued coverage if needed. There is no fee for renewal applications.

To obtain initial coverage, a discharger needs to develop a stormwater pollution prevention plan (SWPPP) and submit a complete Notice of Intent (NOI) form and pay the appropriate application fee prior to the commencement of construction activity. These must occur at least 45 days prior for sites within the Big Darby Creek and portions of the Olentangy River watersheds (including attaching SWP3 to NOI); and at least 21 days elsewhere.

As has been required in previous generations of the permit, a Stormwater Pollution Prevention Plan (SWPPP) is required to be prepared prior to submitting an NOI for coverage under the General Permit. The renewed permit is largely the same as the previous version. For additional information related to the Construction Stormwater General Permit, visit this link on the Ohio EPA website.
