Authority: IC 15-16-2-1.5
Affected: IC 15-16-2; IC 25-17.6
Sec. 2.
(a) A storage
structure must be designed as follows:
(1) The
bottom of the storage structure is at least two (2) feet above
bedrock.
(2) The bottom of the
storage structure must be above the seasonal high water table, unless lowered
in accordance with subsection (c).
(3) Test holes to obtain soil and water table
information for the design must be obtained as follows:
(A) The number of test holes must be
sufficient to adequately characterize the seasonal water table and soil
underneath the storage structure.
(B) Test holes must be:
(i) evenly distributed throughout the storage
structure;
(ii) at least two (2)
feet below the base of the storage structure for concrete structures in karst
and non-karst areas;
(iii) at least
five (5) feet below the base of the storage structure for earthen structures in
non-karst areas; and
(iv) placed to
the shallower of either:
(AA) bedrock;
or
(BB) ten (10) feet below the
lowest point of the proposed processed manure storage structure;
in areas of karst terrain.
(C) Testing shall be conducted by:
(i) a soil scientist registered under the
Indiana board of registration for soil scientists;
(ii) a professional geologist certified in
Indiana under IC 25-17.6; or
(iii)
a professional engineer registered in Indiana.
(b) Plastic, fiberglass, and
aboveground steel tanks must:
(1) have
sufficient strength to withstand design loads;
(2) be watertight;
(3) be cleaned to remove any traces of
previously stored substances prior to addition of manure to the tank if the
tank is used to store any objectionable or hazardous substances;
(4) be installed to ensure the seasonal high
water table is maintained below the tank or the tank must be anchored to
prevent flotation; and
(5) have
protected shut-off valves for all inlet and outlet pipes.
(c) Any drainage system to lower the seasonal
water table around the base of a storage structure must be designed and
installed to:
(1) effectively collect and
drain the ground water;
(2) be of
adequate size, proper slopes, and proper distance from the storage
structure;
(3) if applicable, be
provided with:
(A) sumps;
(B) pumps, including a backup pump;
and
(C) electricity
supply;
(4) if
applicable, have a surface outlet that is at least fifty (50) feet away from
the storage structure, and at least:
(A)
fifty (50) feet from the property line in soils with a permeability of one-half
(1/2) inch per hour or less; or
(B)
twenty (20) feet from the property line in soils with a permeability greater
than one-half (1/2) inch per hour;
(5) have a shut-off valve or equivalent;
and
(6) have an access point for
sampling within fifty (50) feet of the storage structure.
(d) A concrete storage structure must be
constructed according to the Indiana NRCS Construction Specification, Concrete
Construction, May 2015* and designed to either of the following design
standards:
(1) MWPS-36: Rectangular Concrete
Manure Storages, Second Edition, 2005**.
(2) TR-9: Circular Concrete Manure Tanks,
March 1998**.
(e) A
storage structure must not:
(1) have a
discharge pipe or conveyance that would allow for a release or discharge of
processed manure or water contaminated by processed manure; or
(2) be an underground steel storage tank.
