Mont. Admin. R. 17.30.1330 - CONCENTRATED ANIMAL FEEDING OPERATIONS
(1)
Concentrated animal feeding operations (CAFOs), as defined in
75-5-801, MCA, or designated in
accordance with (5) through (7), are point sources subject to the MPDES
requirements as provided in this rule. Once an animal feeding operation is
defined as a CAFO for at least one type of animal, the MPDES requirements for
CAFOs apply with respect to all animals in confinement at the operation and all
manure, litter, and process wastewater generated by those animals or the
production of those animals, regardless of the type of animal.
(2) A CAFO must not discharge a pollutant to
state surface waters unless the discharge is authorized under an MPDES permit.
In order to obtain authorization under an MPDES permit, the CAFO owner or
operator must either apply for an individual permit or submit a notice of
intent for coverage under a general permit.
(3) An application for an individual permit
must include the information specified in ARM
17.30.1322(9). A
notice of intent to be covered under a general permit must include the
information specified in ARM
17.30.1322(9) and
40 CFR
122.28(b).
(4) CAFOs that meet the requirements of 40
CFR Part 412 must be authorized by the department under a general permit,
unless the department discovers site-specific information that indicates a
general permit is not sufficiently protective of water quality during its
review under (8). If the department determines that a general permit is not
sufficient to protect water quality, the department shall require an individual
permit for the CAFO.
(5) On a
case-by-case basis, the department may designate any animal feeding operation
as a concentrated animal feeding operation upon determining that it is a
significant contributor of pollution to state waters. In making this
designation the department shall consider the following factors:
(a) the size of the animal feeding operation
and the amount of wastes reaching state waters;
(b) the location of the animal feeding
operation relative to state waters;
(c) the means of conveyance of animal wastes
and process waste waters into state waters;
(d) the slope, vegetation, rainfall, and
other factors affecting the likelihood or frequency of discharge of animal
wastes and process waste waters into state waters; and
(e) other relevant factors.
(6) No animal feeding operation
with less than the numbers of animals set forth in 40 CFR Part 122.23 may be
designated as a CAFO unless:
(a) pollutants
are discharged into state waters through a manmade ditch, flushing system, or
other similar manmade device; or
(b) pollutants are discharged directly into
state waters which originate outside of the facility and pass over, across, or
through the facility or otherwise come into direct contact with the animals
confined in the operation.
(7) A permit application is not required from
a concentrated animal feeding operation designated under this rule until the
department has conducted an on-site inspection of the operation and determined
that the operation should and could be regulated under the permit
program.
(8) The department shall
review notices of intent submitted by CAFO owners for coverage under a general
permit according to the procedures in
40 CFR
122.23(h)(1).
(9) The discharge of manure, litter, or
process wastewater from a CAFO's land application area to state surface waters
is subject to MPDES requirements, except where the discharge is an agricultural
storm water discharge, as defined in
40 CFR
122.23(e).
(10) The department adopts and incorporates
by reference the following federal regulations, which may be obtained from the
Department of Environmental Quality, Water Protection Bureau, P.O. Box 200901,
Helena, MT 59620:
(a)
40 CFR
122.23 (except
40 CFR
122.23(d), (f), (g), (i), and
(j)) (July 1, 2012), which specifies permit
application requirements, definitions, and procedures for issuing individual or
general permits to CAFOs.
(b)
40 CFR
122.28(b)(2)(vii) (July 1,
2012), which sets forth informational requirements for notices of intent
submitted by CAFOs.
