Thursday, May 18, 2017

The new Ohio Industrial Storm Water General Permit was issued May 8, 2017 and will become effective June 1, 2017.

Key Changes:

Parts 1.3.1, 1.4.1, and 1.5

NOI, NOT and NOE must be submitted electronically via Ohio EPA's eBusiness Center

Part 4.3

Comprehensive site inspection and routine facility inspection are consolidated into one set of procedures to eliminate redundancies and reduce burden (4 inspections instead of 5)


Language added to allow permittees obtaining coverage in years 4 and 5 of this permit to complete benchmark monitoring to the extent of remaining monitoring periods available before permit expires

Both new facilities and facilities renewing coverage will be required to conduct benchmark monitoring even if such monitoring was completed during the previous permit term

Language added to provide a procedure for permittees to document and account for an exceeded benchmark due to a neighboring facility's storm water run-on

Part 7.2 & Appendix I

Annual report modified to be consistent with U.S. EPA's 2015 MSGP annual report form; it has been streamlined and the comprehensive site inspection component has been removed
