327 IAC 6.1-8-4 Performance standards and construction standards for storage structures for liquid biosolid or industrial waste product, and pollutant-bearing water
Cite as Ind. Admin. Code tit. 327, r. 6.1-8-4
Sec. 4. Except for lagoons, storage structures for liquid biosolid or industrial waste product and for pollutant-bearing water must be
constructed and maintained in accordance with the following:
(1) The structure material and wall thickness must be adequate to contain the contents.
(2) Steel tanks must be coated to prevent corrosion.
(3) Structures constructed of materials other than steel must have prior approval of the commissioner and must be coated if necessary
to prevent corrosion or afford further protection from leakage.
(4) The storage structures must be adequately anchored, supported, and bedded to provide structural safety and prevent its
movement.
(5) The structure must be supported by a concrete base.
(6) The bottom of any storage structure must be at least two (2) feet above the bedrock.
(7) The bottom of the storage structure must be at least two (2) feet above the water table. The depth to the water table must be
determined using:
(A) soil survey data established by the USDA Natural Resource Conservation Service; or
(B) information obtained from a professional soil scientist registered under IC 25-31.5-4;
unless it can be demonstrated that the water table has been or will be artificially lowered to two (2) feet or more from the bottom of
the storage structure prior to use of the storage structure.
(8) Any discharge pipe from the storage structure must be equipped with a water-tight valve and a sanitary cap or plug.
(9) The storage structure must be of such construction or design as to allow inspection and sampling of the contents in the
structure.
(10) The receiving or inlet facility or opening must be constructed or designed to prevent nuisance conditions, safety hazards, or the
harborage and breeding of vectors.
(11) The structure must be constructed to prevent leaks and seepage and prevent spills that could enter surface waters or ground
water.
