(A) As used in this section:
(1) "Method detection limit" has the same meaning as in 40 C.F.R. part 136, appendix B, and shall be determined in accordance with the procedures set forth in that appendix.
(2) "Practical quantification level" means a concentration that is five times the method detection limit for the most sensitive available analytical procedure currently approved under 40 C.F.R. part 136 for a pollutant unless the director of environmental protection, by rules adopted in accordance with Chapter 119. of the Revised Code, establishes a different practical quantification level for the pollutant that is consistent with and no more stringent than the appropriate national consensus standard or other generally accepted standard.
(B) Notwithstanding any other provisions of this chapter to the contrary, and until the director has adopted rules specifying a different basis for determining compliance consistent with and no more stringent than an appropriate national consensus standard or other generally accepted standard, if a discharge limit is set below the practical quantification level for a particular parameter, any value reported at or below the practical quantification level shall be considered to be in compliance with that limit.
(C) Whenever a discharge limit for a pollutant is less than the practical quantification level, the director may require the permit holder to identify the possible sources of that pollutant. The director, by rule, may specify additional actions that the permit holder may be required to take when the director finds the actions to be necessary to prevent or mitigate significant adverse effects on public health or environmental quality. Failure of a permit holder to comply with additional actions required by the director under this division constitutes a violation of the permit holder's discharge permit.
