Section 6111.031. Modification of terms and conditions of permit

(A) The director of environmental protection, where consistent with the "Federal Water Pollution Control Act," may modify the terms and conditions of a permit or issue a permit upon conditions at variance from a national effluent limitation set under section 301 of the "Federal Water Pollution Control Act" upon application filed therefor after July 1, 1977, and a showing satisfactory to the director that such modified terms and conditions (1) will require the maximum use of technology within the economic capability of the owner or operator, and (2) will result in reasonable further progress toward the elimination of the discharge of sewage, industrial waste, and other wastes into the waters of the state.

(B) The director may, after opportunity for a public hearing in accordance with section 3745.07 of the Revised Code, issue a permit upon conditions at variance from a national or state effluent limitation for the thermal component of a discharge, upon a showing satisfactory to the director that the national or state limitation for the thermal component is more stringent than necessary to assure the protection and propagation of a balanced, indigenous population of shellfish, fish, and wildlife in and on the body of water into which the discharge is made or is to be made. If the director so finds, he shall impose a limitation on the thermal component, as a condition of the permit, that will assure the protection and propagation of a balanced, indigenous population of shellfish, fish, and wildlife in and on the body of water into which the discharge is made or is to be made, taking into account the interaction of such thermal component with sewage, industrial waste, or other wastes, and including a margin of safety that takes into account any lack of knowledge concerning the development of thermal water quality criteria for such purposes.
