Ohio EPA Proposes Rule Changes to Pretreatment and Indirect Discharge Program

Ohio EPA is proposing to amend rules that regulate allowable industrial wastewater discharges that require pretreatment before being routed to public wastewater treatment systems.

Wednesday, July 11
10:30 a.m. at Ohio EPA, Conference Room A,
50 West Town Street, Suite 700, Columbus

A public hearing on the proposed changes will be held on Wednesday, July 11, 2012, at 10:30 a.m. at Ohio EPA, Conference Room A, 50 West Town Street, Suite 700, Columbus.

Proposed changes to the rule being proposed include:

  • add a definition for non-contact cooling water;
  • add administrative requirements for a toxic organics management plan; and
  • clarify that all information submitted to the state or a publicly owned treatment plant must be available for public access.

Industrial users discharge process wastewater that is often contaminated with a variety of toxic or harmful substances which publically owned treatment facilities are typically not specifically designed to treat and clean. Therefore, pretreatment programs are necessary to eliminate the potential of serious harm to the environment or human health when discharged into public sewer systems. This pretreatment is required by the federal Clean Water Act. These rule changes are part of Ohio EPA's five-year rule review.
