Each
toxic pollutant listed in accordance with paragraph (1) of this subsection shall be subject to
effluent limitations resulting from the application of the best available technology economically achievable for the applicable category or class of
point sources established in accordance with sections
1311(b)(2)(A) and
1314(b)(2) of this title. The Administrator, in his discretion, may publish in the Federal Register a proposed effluent standard (which may include a prohibition) establishing requirements for a
toxic pollutant which, if an
effluent limitation is applicable to a class or category of
point sources, shall be applicable to such category or class only if such standard imposes more stringent requirements. Such published effluent standard (or prohibition) shall take into account the toxicity of the
pollutant, its persistence, degradability, the usual or potential presence of the affected organisms in any waters, the importance of the affected organisms and the nature and extent of the effect of the
toxic pollutant on such organisms, and the extent to which effective control is being or may be achieved under other regulatory authority. The Administrator shall allow a period of not less than sixty days following publication of any such proposed effluent standard (or prohibition) for written comment by interested
persons on such proposed standard. In addition, if within thirty days of publication of any such proposed effluent standard (or prohibition) any interested
person so requests, the Administrator shall hold a public hearing in connection therewith. Such a public hearing shall provide an opportunity for oral and written presentations, such cross-examination as the Administrator determines is appropriate on disputed issues of material fact, and the transcription of a verbatim record which shall be available to the public. After consideration of such comments and any information and material presented at any public hearing held on such proposed standard or prohibition, the Administrator shall promulgate such standard (or prohibition) with such modification as the Administrator finds are justified. Such promulgation by the Administrator shall be made within two hundred and seventy days after publication of proposed standard (or prohibition). Such standard (or prohibition) shall be final except that if, on judicial review, such standard was not based on substantial evidence, the Administrator shall promulgate a revised standard.
Effluent limitations shall be established in accordance with sections
1311(b)(2)(A) and
1314(b)(2) of this title for every
toxic pollutant referred to in table 1 of Committee Print Numbered 95–30 of the Committee on Public Works and Transportation of the
House of Representatives as soon as practicable after
December 27, 1977, but no later than
July 1, 1980. Such
effluent limitations or effluent standards (or prohibitions) shall be established for every other
toxic pollutant listed under paragraph (1) of this subsection as soon as practicable after it is so listed.
