Affected: IC 13-14-12; IC 13-18-10; IC 13-30
Sec. 7.
(a) All
				permitted CAFOs must comply with the requirements of
				327 IAC
				19-3-1.
(b) Animals in any confinement area must not
				have direct access to waters of the state.
(c) A discharge of process wastewater
				pollutants to waters of the state is prohibited, except as described in
				subsection (d).
(d) Whenever
				rainfall events cause an overflow of process wastewater from a facility
				designed, constructed, operated, and maintained to contain all process
				wastewater generated in addition to the runoff from a twenty-five (25) year,
				twenty-four (24) hour rainfall event for the location of the point source,
				process wastewater pollutants in the overflow may be discharged into waters,
				provided that the production area is operated in accordance with the
				requirements of
				40 CFR
				412.37(a) * and
				40 CFR
				412.37(b) *.
(e) Any discharges by operations permitted
				under this rule may not cause an exceedance of a water quality standard under
				327 IAC 2.
(f) Permitted CAFOs must
				meet the following requirements and effluent limitations for the CAFO
				production areas as of the date of permit coverage:
(1) A discharge of manure, litter, or process
				wastewater pollutants to waters of the state is prohibited.
(2) Whenever rainfall events cause an
				overflow of process wastewater from a structure designed, constructed,
				operated, and maintained to contain all process wastewater including the direct
				precipitation and runoff from a twenty-five (25) year, twenty-four (24) hour
				rainfall event for the location of the point source, process wastewater
				pollutants in the overflow may be discharged into waters, provided that the
				production area is operated in accordance with the requirements of subdivisions
				(3) through (7).
(3) Conduct weekly
				visual inspections of all of the following:
(A) Storm water diversion devices.
(B) Runoff diversion devices.
(C) Devices channeling contaminated storm
				water to the process wastewater and manure storage structure.
(D) Manure, litter, and process wastewater
				impoundments, noting the level in open surface liquid impoundments as indicated
				by the depth marker.
(4)
				Conduct daily inspection of all water lines that may come in contact with or
				impact manure, litter, or process wastewater in and around the production area.
				Water lines include drinking water lines for livestock.
(5) Correct any deficiencies found in
				inspections as soon as possible.
(6) Do not dispose of mortalities in a liquid
				manure or process wastewater system. Mortalities must be handled to prevent the
				discharge of pollutants to surface water.
(7) Maintain, within the operating record
				required under section 11 of this rule, for a period of five (5) years from the
				date of creation, a complete copy of the following records:
(A) Records documenting
				self-inspections.
(B) Weekly
				records of the depth of manure and process wastewater in the open surface
				liquid impoundment, as indicated by the depth marker.
(C) Records of actions taken to correct
				deficiencies. Deficiencies not corrected within thirty (30) days of discovery
				must be accompanied by an explanation of the factors preventing immediate
				correction.
(D) Records of
				mortality management and practices.
(E) Records documenting the current design of
				any manure, litter, or process wastewater storage structures, including volume
				for solids accumulation, design treatment volume, total design volume, and
				approximate number of days of storage capacity.
(F) Records of the date, time, and estimated
				amount of any overflow.
