The Ohio Revised Code (ORC) authorizes the Ohio Department of Health and the Sewage Treatment Technical Advisory Committee (TAC) to review and make recommendations to the Director of Health for the approval of Sewage Treatment Systems (STS) components that achieve different levels of sewage treatment. The ODH and TAC review and approval process is intended to ensure that pretreatment component reliability and effluent quality is achieved and maintained. Effluent quality standards from an STS or a pretreatment component are established through various means. These standards are based on water quality requirements in the National Pollutant Discharge Elimination System (NPDES) permit as required by the Clean Water Act for discharging systems, state-established standards for discharge into the soil, local health district requirements for nutrient reduction (nitrogen and phosphorous), and rule provisions related to high-strength waste reduction (small flow or commercial systems).
The approval of the system or component by the Director of Health incorporates by reference the requirements for factory specific training for service providers to ensure proper servicing and maintenance of systems and components. The new sewage treatment systems rules, Ohio Administrative Code Chapter 3701-29, became effective on January 1, 2015 require that service providers obtain factory specific training to service products when required by the manufacturer for all products approved after January 1, 2007.
A complete listing of approved pretreatment systems and components lists components that are approved for one or more of the following: sizing reduction, soil depth credits and NPDES-permitted discharge along with system schematics, system installation and inspection checklists, and operation and maintenance manuals are provided above for each manufacturer authorized for use in Ohio.
