17.30.1207    EFFLUENT LIMITATIONS AND STANDARDS OF PERFORMANCE

(1) Permits issued to point source dischargers, other than POTWs, must include effluent limitations or standards of performance applicable to the point source that are set forth in 40 CFR Chapter I, Subchapter N, as provided below:

(a) for existing sources, effluent limitations representing the degree of effluent reduction attainable by the application of:

(i) the best practicable control technology currently achievable (BPT) for all pollutants;

(ii) the best available technology economically achievable (BAT) for toxic and nonconventional pollutants; and

(iii) the best conventional pollutant control technology (BCT) for conventional pollutants;

(b) for new sources, new source performance standards (NSPS) reflecting the best available demonstrated control technology, processes, operating methods, or other alternatives, including, where practicable, a standard permitting no discharge.

(2) The department shall ensure that the applicable effluent limitations or standards of performance set forth in 40 CFR Chapter I, Subchapter N, are included in any new MPDES permit, renewed MPDES permit, or permit modification issued in accordance with ARM Title 17, chapter 30, subchapter 13.

(3) The board adopts and incorporates by reference 40 CFR Chapter I, Subchapter N (except 40 CFR Part 403) (July 1, 2010), which sets forth federal effluent limitations and standards for existing sources and standards of performance for new sources, which are promulgated by EPA under sections 301, 304(b), 306(b), and 316(b) of the federal Clean Water Act. 40 CFR Part 403, which is excluded from this incorporation by reference, sets forth general pretreatment requirements for new and existing sources.
