The revised permit includes some of the same requirements that were included in the current OEPA industrial stormwater permit. However, some significant changes have also been included, especially relating to stormwater monitoring requirements. The OEPA permit was modeled after the US EPA multi-sector general permit (MSGP), released in 2008. To comply with Ohio Administrative Code 3745-1-05 Antidegradation Rules, dischargers to Superior High Quality Waters, Outstanding State Waters, and Outstanding National Resource Waters, excluding Lake Erie can not use this permit, and would need to seek permit coverage by other means.
