Ohio Revised Code Title LXI. Water Supply Sanitation Ditches § 6111.13

(A) As used in this section:

(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 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.
