(3 I If the Administrator, within sixty days after 

 the date of submission of the revised or new stand- 

 ard, determines that such standard meets the re- 

 quirements of this chapter, such standard shall 

 thereafter be the water, quality standard for the ap- 

 plicable waters of that State. If the Administrator 

 determines that any such revised or new standard is 

 not consistent with the applicable requirements of 

 this chapter, he shall not later than the ninetieth day 

 after the date of submission of such standard notify 

 the State and specify the changes to meet such re- 

 quirements. If such changes are not adopted by the 

 State within ninety days after the date of notifica- 

 tion, the Administrator shall promulgate such stand- 

 ard pursuant to paragraph i4) of this subsection. 



(4) The Administrator shall promptly prepare and 

 publish proposed regulations setting forth a revised 

 or new water quality standard for the navigable 

 waters involved — 



'A) if a revised or new water quality standard 

 submitted by such State under paragraph i3> of 

 this subsection for such waters is determined by 

 the Administrator not to be consistent with the 

 applicable requirements of this chapter, or 



(Bi in any case where the Administrator deter- 

 mines that a revised or new standard is necessary 

 to meet the requirements of this chapter. 

 The Administrator .shall promulgate any revised or 

 new standard under this paragraph not later than 

 ninety days after he publishes such proposed stand- 

 ards, unless prior to such promulgation, such State 

 has adopted a revised or new water quality standard 

 which the Administrator determines to be in accord- 

 ance with this chapter. 



(d) Identification of areas with insufficient controls; 

 maxim\im daily load. 

 (l>(Ai Each State shall identify those waters 

 within its boundaries for which the effluent limita- 

 tions required by section 1311'bi il) (Ai and section 

 1 3 II ( b ) 1 1 1 ( B ) of this title are not stringent enough 

 to implement any water quality standard applicable 

 to such waters. The State shall establish a priority 

 ranking for such waters, taking into account the 

 severity of the pollution and the uses to be made of 

 such waters. 



(B) Each State shall identify those waters or parts 

 thereof within its boundaries for which controls on 

 thermal discharges under section 1311 of this title 

 are not stringent enough to assure protection and 

 propaeation of a balanced indigenous population of 

 shellfish, fish, and wildlife. 



(C) Each State shall establish for the waters iden- 

 tified in paragraph 'IWAi of this subsection, and 

 In accordance with the priority ranking, the total 

 maximum daily load, for those pollutants which the 

 Administrator identifies under section 1314<a) <2) of 

 this title as suitable for such calculation. Such load 

 shall be established at a level nece.-isary to imple- 

 ment the applicable Water quality standards w-ith 

 seasonal variations and a margin of safety which 

 takes into account any lack of knowledge concerning 

 the relationship between effluent limitations and 

 water quality. 



(D) Each State shall estimate for the waters 

 identified in paragraph (1) (B) of this subsection the 

 total maximum daily thermal load required to as- 



sure protection and propagation of a balanced, in- 

 digenous population of shellfish, fish and wildlife. 

 Such estimates shall take into account the normal 

 water temperatures, flow rates, seasonal variations, 

 existing sources of heat input, and the dissipative 

 capacity of the identified waters or parts thereof. 

 Such estimates shall include a calculation of the 

 maximum heat input that can be made into each 

 such part and shall include a margin of safety which 

 takes into account any lack of knowledge concern- 

 ing the development of thermal water quality cri- 

 teria for such protection and propagation in the 

 identified waters or parts thereof. 



(2) Each State shall submit to the Administrator 

 from time to time, with the first such submission not 

 later than one hundred and eighty days after the 

 date of publication of the first identification of pol- 

 lutants under section 1314iaH2i(Di of this title, 

 for his approval the waters identified and the loads 

 established under paragraphs <1WA). (IXBK ai 

 (C^ , and (IHD) of this subsection. The Administra- 

 tor shall either approve or disapprove such identi- 

 fication and load not later than thirty days after the 

 date of submission. If the Administrator approves 

 such identification and load, such State shall incor- 

 porate them into its current plan under subsection 

 (el of this section. If the Administrator disapproves 

 such identification and load, he shall not later than 

 thirty days after the date of such disapproval iden- 

 tify such waters in such State and establish such 

 loads for such waters as he determines necessary to 

 implement the water quality standards applicable to 

 such waters and upon such identification and es- 

 tablishment the State shall incorporate them into 

 its current plan under subsection le) of this section. 

 (3i For the specific purpose of developing infor- 

 mation, each State shall identify all waters within 

 its boundaries which it has not identified under 

 paragraph il)<A) and (liiBi of this subsection 

 and estimate for such waters the total maximum 

 daily load with seasonal variations and margins of 

 safety, for those pollutants which the Administrator 

 identifies under section 1314iaii2) of this title as 

 suitable for such calculation and for thermal dis- 

 charges, at a level that would assure protection and 

 propagation of a balanced indigenous population of 

 fish, shellfish and wildlife. 



(e) Continuing planning process. 



Ill Each State shall have a continuing planning 

 process approved under paragraph '2) of this sub- 

 section which is consistent with this chapter. 



(2) Each State shall submit not later than 120 

 days after October 18. 1972. to the Administrator for 

 his approval a proposed continuing planning process 

 which is consistent with this chapter. Not later than 

 thirty days after the date of submission of such a 

 process the Administrator shall either approve or 

 disapprove such process. The Administrator shall 

 from time to time review each State's approved plali- 

 ning process for the purpose of insuring that such 

 planning process is at all times consistent with this 

 chapter. The Administrator shall not approve any 

 State permit program under subchapter IV of this
