25 Pa. Code § 92a.48 - Industrial waste permit

(a) Industrial waste regulated by this chapter must meet the following requirements:

(1) EPA-promulgated effluent limitation guidelines established under section 304(b) of the Federal Act (33 U.S.C.A. § 1314(b)).

(2) Compliance with § 95.2 (relating to effluent standards for industrial waste).

(3) For those industrial categories for which no effluent limitations have been established under paragraph (1), Department-developed technology-based limitations established in accordance with 40 CFR 125.3 (relating to technology-based treatment requirements in permits).

(b) For facilities or activities using chlorination, the following apply:

(1) If the EPA adopts a National categorical ELG promulgating limits for Total Residual Chlorine (TRC) or free available chlorine for a specific industry or activity under section 301 or 304(b) of the Federal Act (33 U.S.C.A. §§ 1311 and 1314(b)), that ELG constitutes BAT for the industry or activity. If the EPA has not promulgated a National ELG for TRC or free available chlorine for an industry or activity, the Department may develop a facility-specific BAT effluent limitation for TRC. Factors, which will be considered in developing a facility-specific BAT effluent limitation, include the following:

(i) The age of equipment and facilities involved.

(ii) The engineering aspects of the application of various types of control techniques and alternatives to the use of chlorine or reductions in the volume of chlorine used during the disinfection process.

(iii) The cost of achieving the effluent reduction.

(iv) Nonwater quality environmental impacts (including energy requirements).

(v) Other factors the Department deems appropriate.

(2) For facilities where the EPA has not promulgated a National ELG setting forth limits for TRC or free available chlorine for an industry or activity, and the Department has not developed a facility-specific BAT effluent limitation for TRC under the factors in paragraph (1), an effluent limitation for TRC of 0.5 milligrams per liter (30-day average) constitutes BAT.

(3) Facilities using chlorination that discharge to an Exceptional Value Water, or to a High Quality Water where economic or social justification under § 93.4c(b) (1)(iii) (relating to implementation of antidegradation requirements) has not been demonstrated under applicable State or Federal law or regulations, shall discontinue chlorination or dechlorinate their effluents prior to discharge into the waters.
