§1312 Water quality related effluent limitations

Title 33 › Chapter CHAPTER 26— - WATER POLLUTION PREVENTION AND CONTROL › Subchapter SUBCHAPTER III— - STANDARDS AND ENFORCEMENT › § 1312

Last updated Apr 6, 2026|Official source

Summary

The Administrator must set pollution limits for a pipe or group of pipes that discharge waste when those discharges would stop a part of a waterway from reaching or keeping water that protects health, drinking water, farms, industry, fish, shellfish, wildlife, and recreation. The limits can include other control methods that should help the water meet those goals. Before any new limit is final, the Administrator must publish the proposal and hold a public hearing within 90 days. With the State’s agreement, the Administrator can change a limit for non-toxic pollutants if the applicant proves at the hearing that the economic and social costs are not reasonably matched by the benefits. For toxic pollutants, the Administrator with the State can allow a modified limit for one period not to exceed 5 years if the applicant shows it is the most control they can afford and will make reasonable progress beyond existing technology-based limits. Setting these water-quality limits cannot delay other law-required limits.

Navigation and Navigable Waters — Source: USLM XML via OLRC

(a)Whenever, in the judgment of the Administrator or as identified under section 1314(l) of this title, discharges of pollutants from a point source or group of point sources, with the application of effluent limitations required under section 1311(b)(2) of this title, would interfere with the attainment or maintenance of that water quality in a specific portion of the navigable waters which shall assure protection of public health, public water supplies, agricultural and industrial uses, and the protection and propagation of a balanced population of shellfish, fish and wildlife, and allow recreational activities in and on the water, effluent limitations (including alternative effluent control strategies) for such point source or sources shall be established which can reasonably be expected to contribute to the attainment or maintenance of such water quality.
(b)(1)Prior to establishment of any effluent limitation pursuant to subsection (a) of this section, the Administrator shall publish such proposed limitation and within 90 days of such publication hold a public hearing.
(2)(A)The Administrator, with the concurrence of the State, may issue a permit which modifies the effluent limitations required by subsection (a) of this section for pollutants other than toxic pollutants if the applicant demonstrates at such hearing that (whether or not technology or other alternative control strategies are available) there is no reasonable relationship between the economic and social costs and the benefits to be obtained (including attainment of the objective of this chapter) from achieving such limitation.
(B)The Administrator, with the concurrence of the State, may issue a permit which modifies the effluent limitations required by subsection (a) of this section for toxic pollutants for a single period not to exceed 5 years if the applicant demonstrates to the satisfaction of the Administrator that such modified requirements (i) will represent the maximum degree of control within the economic capability of the owner and operator of the source, and (ii) will result in reasonable further progress beyond the requirements of section 1311(b)(2) of this title toward the requirements of subsection (a) of this section.
(c)The establishment of effluent limitations under this section shall not operate to delay the application of any effluent limitation established under section 1311 of this title.
