(A) Final limitations.
(B) Interim limitations. Except as provided in paragraph (F) of this rule, the director may establish limits on the levels of pollutants that may be discharged during the period of the compliance program.
(C) Characterization of discharge levels.
(D) Present discharge levels. The director may fix the maximum levels of pollutants specified in an Ohio NPDES permit as either final limitations or interim limitations at the levels indicated by the applicant as its current maximum levels of discharge, even where limitations to such discharge levels are not essential to avoid violation of either applicable water quality standards or effluent standards.
(E) Treatment system design levels. The director may establish limitations for any discharge based on the level of performance that a proposed treatment system is designed to achieve, as documented in an approved permit to install under Chapter 3745-42 of the Administrative Code. These limitations are limited to those pollutants that the proposed treatment system is designed to remove.
(F) Antibacksliding.
(G) Schedules of compliance.
A point source that commenced discharge after March 23, 1997, or a recommencing discharger, shall install and have in operating condition, and shall "start-up" all pollution control equipment required to meet the conditions of its permits before beginning to discharge. Within the shortest feasible time (not to exceed ninety days), the owner or operator must meet all permit conditions. The requirements of this paragraph do not apply if the owner or operator is issued a permit containing a compliance schedule under 40 C.F.R. 122.47(a)(2).
