PART 132--WATER QUALITY GUIDANCE FOR THE GREAT LAKES SYSTEM--Table of Contents
 
Sec. 132.4  State adoption and application of methodologies, policies and 
procedures.

    (a) The Great Lakes States and Tribes shall adopt requirements 
applicable to waters of the Great Lakes System for the purposes of 
sections 118, 301, 303, and 402 of the Clean Water Act that are 
consistent with:
    (1) The definitions in Sec. 132.2;
    (2) The Methodologies for Development of Aquatic Life Criteria and 
Values in appendix A of this part;
    (3) The Methodology for Development of Bioaccumulation Factors in 
appendix B of this part;
    (4) The Methodologies for Development of Human Health Criteria and 
Values in appendix C of this part;
    (5) The Methodology for Development of Wildlife Criteria in appendix 
D of this part;
    (6) The Antidegradation Policy in appendix E of this part; and
    (7) The Implementation Procedures in appendix F of this part.
    (b) Except as provided in paragraphs (g), (h), and (i) of this 
section, the Great Lakes States and Tribes shall use methodologies 
consistent with the methodologies designated as Tier I methodologies in 
appendixes A, C, and D of this part, the methodology in appendix B of 
this part, and the procedures in appendix F of this part when adopting 
or revising numeric water quality criteria for the purposes of section 
303(c) of the Clean Water Act for the Great Lakes System.
    (c) Except as provided in paragraphs (g), (h), and (i) of this 
section, the Great Lakes States and Tribes shall use methodologies and 
procedures consistent with the methodologies designated as Tier I 
methodologies in appendixes A, C, and D of this part, the Tier II 
methodologies in appendixes A and C of this part, the methodology in 
appendix B of this part, and the procedures in appendix F of this part 
to develop numeric criteria and values when implementing narrative water 
quality criteria adopted for purposes of section 303(c) of the Clean 
Water Act.
    (d) The water quality criteria and values adopted or developed 
pursuant to paragraphs (a) through (c) of this section shall apply as 
follows:
    (1) The acute water quality criteria and values for the protection 
of aquatic life, or site-specific modifications thereof, shall apply to 
all waters of the Great Lakes System.
    (2) The chronic water quality criteria and values for the protection 
of aquatic life, or site-specific modifications thereof, shall apply to 
all waters of the Great Lakes System.
    (3) The water quality criteria and values for protection of human 
health, or site-specific modifications thereof, shall apply as follows:
    (i) Criteria and values derived as HCV-Drinking and HNV-Drinking 
shall apply to the Open Waters of the Great Lakes, all connecting 
channels of the Great Lakes, and all other waters of the Great Lakes 
System that have been designated as public water supplies by any State 
or Tribe in accordance with 40 CFR 131.10.
    (ii) Criteria and values derived as HCV-Nondrinking and HNV-
Nondrinking shall apply to all waters of the Great Lakes System other 
than those in paragraph (d)(3)(i) of this section.
    (4) Criteria for protection of wildlife, or site-specific 
modifications thereof, shall apply to all waters of the Great Lakes 
System.
    (e) The Great Lakes States and Tribes shall apply implementation 
procedures consistent with the procedures

in appendix F of this part for all applicable purposes under the Clean 
Water Act, including developing total maximum daily loads for the 
purposes of section 303(d) and water quality-based effluent limits for 
the purposes of section 402, in establishing controls on the discharge 
of any pollutant to the Great Lakes System by any point source with the 
following exceptions:
    (1) The Great Lakes States and Tribes are not required to apply 
these implementation procedures in establishing controls on the 
discharge of any pollutant by a wet weather point source. Any adopted 
implementation procedures shall conform with all applicable Federal, 
State and Tribal requirements.
    (2) The Great Lakes States and Tribes may, but are not required to, 
apply procedures consistent with procedures 1, 2, 3, 4, 5, 7, 8, and 9 
of appendix F of this part in establishing controls on the discharge of 
any pollutant set forth in Table 5 of this part. Any procedures applied 
in lieu of these implementation procedures shall conform with all 
applicable Federal, State, and Tribal requirements.
    (f) The Great Lakes States and Tribes shall apply an antidegradation 
policy consistent with the policy in appendix E for all applicable 
purposes under the Clean Water Act, including 40 CFR 131.12.
    (g) For pollutants listed in Table 5 of this part, the Great Lakes 
States and Tribes shall:
    (1) Apply any methodologies and procedures acceptable under 40 CFR 
part 131 when developing water quality criteria or implementing 
narrative criteria; and
    (2) Apply the implementation procedures in appendix F of this part 
or alternative procedures consistent with all applicable Federal, State, 
and Tribal laws.
    (h) For any pollutant other than those in Table 5 of this part for 
which the State or Tribe demonstrates that a methodology or procedure in 
this part is not scientifically defensible, the Great Lakes States and 
Tribes shall:
    (1) Apply an alternative methodology or procedure acceptable under 
40 CFR part 131 when developing water quality criteria; or
    (2) Apply an alternative implementation procedure that is consistent 
with all applicable Federal, State, and Tribal laws.
    (i) Nothing in this part shall prohibit the Great Lakes States and 
Tribes from adopting numeric water quality criteria, narrative criteria, 
or water quality values that are more stringent than criteria or values 
specified in Sec. 132.3 or that would be derived from application of the 
methodologies set forth in appendixes A, B, C, and D of this part, or to 
adopt antidegradation standards and implementation procedures more 
stringent than those set forth in appendixes E and F of this part.
