Rule 901:10-3-03 | Horses and sheep.
This rule applies to discharges resulting from the production areas at horse and sheep concentrated animal feeding operations. This rule does not apply to such concentrated animal feeding operations with less than the following capacities: ten thousand sheep or five hundred horses.
(A) Effluent limitations attainable by the application of the best practicable control technology currently available (BPT).
(1) Except as provided in rule 901:10-3-08 of the Administrative Code, and subject to the provisions of paragraph (A)(2) of this rule, any existing point source subject to this rule must achieve the following effluent limitations representing the application of BPT: there shall be no discharge of manure to waters of the state.
(2) Manure in the overflow may be discharged to waters of the state whenever rainfall events, either chronic or catastrophic, cause an overflow of manure from a facility designed, constructed and operated to contain all manure plus the runoff from a ten-year, twenty-four hour rainfall event for the location of the point source.
(B) Effluent limitations attainable by the application of the best available technology economically achieveable (BAT).
(1) Except as provided in rule 901:10-3-08 of the Administrative Code, and when the provisions of paragraph (B)(2) of this rule apply, any existing point source subject to the rule must achieve the following effluent limitations representing the application of BAT: there shall be no discharge of manure into waters of the state.

(C) Standards of performance for new sources (new source performance standards or "NSPS").
(1) Except as provided in paragraph (C)(2) of this rule, any new source subject to this rule must achieve the following performance standards: there must be no discharge of manure to waters of the state.
(2) Whenever rainfall events cause an overflow of manure from a facility designed, constructed, operated, and maintained to contain all manure plus the runoff from a twenty-five year, twenty-four hour rainfall event at the location of the point source, any manure in the overflow may be discharged into waters of the state.
