Ohio Admin. Code 3745-3-04 - Prohibited discharges

[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules and federal statutory provisions referenced in this rule, see rule 3745-3-01 of the Administrative Code.]

(A) Pollutants introduced into POTWs by an industrial user shall not pass through the POTW or interfere with the operation or performance of the POTW. These general prohibitions and the specific prohibitions in paragraph (B) of this rule apply to all sources of indirect discharge whether or not the source is subject to other national, state, or local pretreatment standards or requirements.

(B) The following described substances shall not be introduced into a POTW:

(1) Pollutants that create a fire or explosion hazard in the POTW including, but not limited to, wastestreams with a closed cup flashpoint of less than sixty degrees Celsius (one hundred forty degrees Fahrenheit), using the test methods specified in 40 C.F.R. 261.21.

(2) Pollutants that will cause corrosive structural damage to the POTW, but in no case discharges with pH lower than 5.0, unless the POTW is specifically designed to accommodate such discharges.

(3) Solid or viscous pollutants in amounts that will cause obstruction to the flow in sewers, or other interference with the operation of the POTW.

(4) Any pollutant, including oxygen demanding pollutants, released in a discharge at a flow rate or pollutant concentration as to cause interference with the POTW.

(5) Heat in amounts that will inhibit biological activity in the POTW treatment plant resulting in interference or causing damage, but in no case heat in such quantities that the temperature exceeds forty degrees Celsius (one hundred four degrees Fahrenheit) at the POTW treatment plant unless the director, upon request of the POTW, approves an alternate temperature limit.

(6) Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through.

(7) Pollutants that result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems.

(8) Any trucked or hauled pollutants, except at discharge points designated by the POTW.

(C) No industrial user shall discharge any pollutant in violation of applicable pretreatment standards.

(D) In cases where pollutants contributed by an industrial user may result or have resulted in interference or pass through of the POTW and such violation is likely to recur, the director may require POTWs that are not required to develop a pretreatment program pursuant to paragraph (A) of rule 3745-3-03 of the Administrative Code, to develop and enforce BMPs and specific technically supported effluent limits for an industrial user, and all other users, as appropriate, that, together with appropriate changes in the POTW treatment plant's facilities or operation, are necessary to ensure renewed and continued compliance with the POTW's NPDES permit, or sludge use or disposal practices.
