40 CFR 133.105 - Treatment equivalent to secondary treatment. | Title 40 - Protection of Environment | Code of Federal Regulations | LII / Legal Information Institute
§ 133.105
Treatment equivalent to secondary treatment.
This section describes the minimum level of effluent quality attainable by facilities eligible for treatment equivalent to secondary treatment ( § 133.101(g)) in terms of the parameters—BOD5, SS and pH. All requirements for the specified parameters in paragraphs (a), (b) and (c) of this section shall be achieved except as provided for in § 133.103, or paragraphs (d), (e) or (f) of this section.
(a) BOD
5. (1) The 30-day average shall not exceed 45 mg/l.
(b) SS.
Except where SS values have been adjusted in accordance with § 133.103(c) :
(c) pH.
The requirements of § 133.102(c) shall be met.
(d) Alternative State requirements.
Except as limited by paragraph (f) of this section, and after notice and opportunity for public comment, the Regional Administrator, or, if appropriate, State Director subject to EPA approval, is authorized to adjust the minimum levels of effluent quality set forth in paragraphs (a)(1), (a)(2), (b)(1) and (b)(2) of this section for trickling filter facilities and in paragraphs (a)(1) and (a)(2) of this section for waste stabilization pond facilities, to conform to the BOD5 and SS effluent concentrations consistently achievable through proper operation and maintenance ( § 133.101(f)) by the median (50th percentile) facility in a representative sample of facilities within a State or appropriate contiguous geographical area that meet the definition of facilities eligible for treatment equivalent to secondary treatment ( § 133.101(g) ).
(e) CBOD
5 limitations:
(1) Where data are available to establish CBOD5 limitations for a treatment works subject to this section, the NPDES permitting authority may substitute the parameter CBOD5 for the parameter BOD5 In §§ 133.105(a)(1), 133.105(a)(2) and 133.105(a)(3), on a case-by-case basis provided that the levels of CBOD5 effluent quality are not less stringent than the following:
(f) Permit adjustments.
Any permit adjustment made pursuant to this part may not be any less stringent than the limitations required pursuant to § 133.105(a) -(e). Furthermore, permitting authorities shall require more stringent limitations when adjusting permits if: (1) For existing facilities the permitting authority determines that the 30-day average and 7-day average BOD5 and SS effluent values that could be achievable through proper operation and maintenance of the treatment works, based on an analysis of the past performance of the treatment works, would enable the treatment works to achieve more stringent limitations, or
