Sec. 1. (a) The pretreatment rules establish a state program to control the discharge of industrial pollutants into publicly owned treatment works (POTWs), as defined in 327 IAC 5-1.5-48, to implement 40 CFR 403 and related provisions of the federal Clean Water Act, 33 U.S.C. 1251.

(b) The state pretreatment program has the following three (3) objectives:

1. (1) To prevent the introduction of pollutants into a POTW that will interfere with the operation of a POTW, including interference with the use or disposal of municipal sludge.
2. (2) To prevent the introduction of pollutants into a POTW that will pass through the treatment works without receiving effective treatment or otherwise be incompatible with such works.
3. (3) To improve opportunities to recycle and reclaim municipal and industrial wastewaters and sludges.

(c) The pretreatment rules apply to:

1. (1) new or existing industries that discharge by direct connection or indirectly by truck, rail, or other means, nondomestic wastes into POTWs; and
2. (2) POTWs that receive or may receive discharges of nondomestic wastes from those industries.
