(a) National Categorical Pretreatment Standards. National categorical pretreatment standards, as promulgated by the U.S. Environmental Protection Agency (EPA) pursuant to the Act, and as applied to those industrial categories set forth in Appendix C following the text of this chapter, shall be met by all dischargers of the regulated industrial categories. An application for modification of the national categorical pretreatment standards may be considered for submittal to the Regional Administrator by the Authority when the Authority's wastewater treatment system achieves consistent removal of the pollutants as defined by 40 CFR 403.7.
(b) State Requirements. State requirements and limitations on discharges to the POTW shall be met by all dischargers which are subject to such standards in any instance in which they are more stringent than Federal requirements and limitations or those in this chapter or in any other applicable ordinance.
(c) Right of Revision. The Authority reserves the right to amend this chapter to provide for more stringent limitations or requirements on discharges to the POTW where deemed necessary to comply with the objectives set forth in Section 922.01.
(d) Dilution. No discharger shall increase the use of potable or process water in any way, nor mix separate waste streams for the purpose of diluting a discharge, as a partial or complete substitute for adequate treatment to achieve compliance with the standards set forth in this chapter.
(e) Supplementary Limitations. No discharger shall discharge wastewater containing concentrations and/or mass limitations exceeding the values listed for the materials enumerated in Appendix D following the text of this chapter.
(f) Local Limits Development. The Authority may develop, update as necessary and enforce technically supported local limits that will protect the POTW against interference and pass through. The Authority may develop BMPs and such BMPs shall be considered local limits and pretreatment standards for the purpose of this rule upon approval by Ohio EPA. The Authority may impose mass limitations on dischargers which are using dilution to meet the pretreatment standards or requirements of this chapter or in other cases where the imposition of mass limitations is deemed appropriate by the Authority.
