EPA Regional Water Quality Standards Contacts table in SUPPLEMENTARY 
INFORMATION to contact your Regional Office.

SUPPLEMENTARY INFORMATION: This document contains a list of State and 
Tribal water quality standards adoptions and revisions which EPA 
approved during the period beginning on April 1, 1998 and ending on May 
30, 2000. The most recent list was published on October 7, 1998 (63 FR 
53911), reflecting State and Tribal submissions of new or revised water 
quality standards that EPA approved during the period September 1, 1995 
through March 31, 1998.
    For each EPA approval action, this document provides a reference to 
the State's or Tribe's regulations that contain the State and Tribal 
water quality standards, followed by the date of State and Tribal 
adoption and/or effectiveness, the date of EPA approval, and a brief 
description of EPA's approval. Additionally, this notice contains a 
listing of Tribes that have obtained EPA approval to administer a water 
quality standards program. It also contains a listing of federal water 
quality standards rulemakings.
    This document does not include the following information: (1) The 
actual text of the water quality standards, (2) any exceptions or 
conditions that apply to EPA's approval, such as portions of the State 
and Tribal standards submissions on which EPA did not take action or 
EPA disapproved, (3) whether approvals were made subject to the results 
of consultation under the Endangered Species Act, (4) Tribal 
application materials submitted to EPA for authorization to administer 
the water quality standards program, or (5) the text of the federal 
water quality standards rulemakings. The text of a State's or Tribe's 
standards and copies of the approval letters may be obtained from the 
State's or Tribe's pollution control agency or the appropriate EPA 
Regional Office (See ``EPA Regional Water Quality Standards Contacts'' 
table). Proprietary publications such as those of the Bureau of 
National Affairs, Inc. also contain the text of State and Tribal water 
quality standards.
    Due to recent changes in EPA's water quality standards regulations 
commonly referred to as the Alaska Rule, this will be the last list of 
water quality standard approvals published as a Federal Register 
notice. The Alaska Rule (published in the Federal Register on April 27, 
2000 and effective as of May 30, 2000) requires that new and revised 
State and Tribal water quality standards be approved by EPA before they 
become effective for Clean Water Act purposes. Prior to the Alaska 
Rule, water quality standards were Clean Water Act-effective once they 
were adopted by states and authorized tribes, regardless of EPA 
approval. The new regulations replaced the requirement for an annual 
publication of EPA approvals (formerly contained at 40 CFR 131.21(d)) 
with the establishment of a repository of Clean Water Act-effective 
water quality standards (referred to as the Clean Water Act Water 
Quality Standards Docket in the Alaska Rule preamble). (See 65 FR 
24641.) With this Federal Register notice, EPA is announcing the 
availability of the Internet version of this repository for all water 
quality standards effective under the Clean Water Act. The public may 
view the effective Federal, State, Territory, and Tribal water quality 
standards at http://www.epa.gov/ost/wqs. This Internet repository will 
be updated periodically to include new and revised water quality 
standards approved by EPA in the future.
    In addition, EPA Regional offices continue to maintain hard copies 
of the effective water quality standards of the States and authorized 
Tribes within their jurisdiction. You may view hard copy versions of 
the effective water quality standards by contacting the appropriate 
Regional EPA Office (See ``EPA Regional Water Quality Standards 
Contacts'' table). With the availability of the effective State, 
Territory, and Tribal

[[Page 29952]]

water quality standards on EPA's web site and through EPA's Regional 
Offices, the Federal Register notice of EPA approvals is now redundant 
and unnecessary.

pursuant to section 22a-426 of the Connecticut General Statutes.
    Effective Date: October 22, 1997 and March 30, 1999.
    EPA Action: Approval on September 17, 1999.
    For the surface waters in the Housatonic and Southwest Coastal 
Basins, Connecticut reclassified ten waterbodies from Class AA to Class 
A, one waterbody segment from Class A to Class AA, and upgraded 11

facilities to reduce combined sewer overflows (CSO) to the Charles 
River. Massachusetts Department of Environmental Protection issued a 
temporary variance to water quality standards for those discharges 
remaining after the CSO control facilities are constructed. The two-
year variance includes a number of requirements designed to ensure the 
implementation of CSO controls. The variance also requires the MWRA to 
participate in an extensive study of water quality problems in the 
Charles River.

that indirect discharges of sewage could be exempt from the State's 
High Quality Waters and Outstanding Resource Waters antidegradation 
provisions; adopting additional narrative criteria concerning water 
quality within mixing zones; deleting an assumption that an ambient 
water quality criterion for a toxic pollutant was met in a waterbody if 
the concentration of that pollutant in a discharge was less than the 
analytical limit of detection; including conditions governing site-
specific studies used to establish instream flow requirements for the 
protection of aquatic habitat and uses; including conditions 
specifically recognizing the need to control human induced water level 
fluctuations and high flows, in addition to human induced low flows, as 
necessary to protect uses; dividing Class A waters into Class A(1) 
Ecological and Class A(2) Water Supply; creating three Class B ``Water 
Management Types'' for future division of Class B waters; and adopting 
a narrative biological criteria for each use classification or 
management type.

EPA Region 2

New York

    Water quality standards for the State of New York as adopted 
pursuant to Title 6 of the New York State Code of Rules and Regulations

    The amended surface water classifications for the four New York 
City water supply reservoirs consist of the reclassification of all or 
portions of the Cannonsville, Neversink, Pepacton, and Schoharie 
Reservoirs from Class ``A'' to Class ``AA,'' such that all portions of 
these four reservoirs are now classified as Class ``AA.''
    Adopted by the State: January 5, 1991.
    Effective Date: January 5, 1991.
    EPA Action: Approval on February 18, 1999.

drainage basin consist of the reclassification of a total of 1,276 
segments in the basin to higher classifications, including the upgrade 
of 1,229 segments from Class ``D.''
    Adopted by the State: February 2, 1991.
    Effective Date: February 2, 1991.
    EPA Action: Approval on February 18, 1999.
    The amended surface water classifications for the Chemung River 
drainage basin consist of the reclassification of a total of 248 
segments in the basin to higher classifications, including the upgrade 
of 209 segments from Class ``D.''
    Adopted by the State: January 12, 1992.
    Effective Date: January 12, 1992.
    EPA Action: Approval on February 18, 1999.
    The amended surface water classifications for the Upper Hudson 
River drainage basin consist of the reclassification of a total of 857 
segments in the basin to higher classifications, including the upgrade 
of 629 segments from Class ``D.''
    Adopted by the State: May 23, 1991.

    Adopted by the State: May 23, 1991.
    Effective Date: May 23, 1991.
    EPA Action: Approval on February 18, 1999.
    The amended surface water classifications for the Lake Erie/Niagara 
River drainage basin consist of the reclassification of a total of 333 
segments in the basin to higher classifications, including the upgrade 
of 297 segments from Class ``D.'' The most significant result of these 
reclassification actions is the upgrade of the numerous segments in 
these drainage basins from Class ``D,'' which provides protection for 
fish survival, to higher classifications which are protective of both 
fish survival and fish propagation. The designated uses for the above-
referenced segments are now fully consistent with the ``fishable/
swimmable'' goals of the Clean Water Act. In those cases where NYSDEC 
has determined that a particular water body segment was unable to 
support fish propagation, and the Class ``D'' designation was retained, 
the State provided individual use attainability analyses (UAAs) to 
support these determinations.

of its water quality standards that were disapproved by EPA on August 
25, 1998. The principal elements addressed in these amendments include: 
The definition of the wildlife propagation and stock watering 
beneficial use; clarification that both existing and designated uses 
are to be protected; completion requirements for a beneficial use 
analysis prior to renewing an existing permit or issuing a new permit 
to discharge to Class 9 waters; application of criteria to protect 
existing and attainable uses and application of numerical criteria to 
Class 9 waters where the discharge or presence of pollutants could 
reasonably be expected to interfere with existing and attainable uses 
of Class 9 waters; provisions governing the in-zone quality for mixing 
zones, including development of the Department's Mixing Zone and 
Dilution Implementation Procedures, August 1998; antidegradation 
provisions, including development of the Department's Antidegradation 
Implementation Procedures, October 1998; clarification that toxic 
pollutants can include the priority pollutants and any other toxic 
pollutants or substances determined by the Secretary to be of concern; 
upgraded the uses for a number of lakes and streams; and changed the 
uses for four lakes from ``cold water marginal'' to ``warm water 
permanent'' based on an analysis showing that the natural conditions 
and a change in the Department of Game Fish and Parks' fishery 
management policy preclude attainment of a cold water fishery.

accordance with Section 518 of the Clean Water Act, for treatment in 
the same manner as a state.

Federal Water Quality Standards Rulemakings

    For purposes of informing the public, EPA is listing those federal 
water quality standards rulemakings taken pursuant to section 303(c)(4) 
of the CWA for the period of April 1, 1998 through May 30, 2000. For 
the full text of the rules, the reader is referred to the Federal 
Register notices cited.

Alaska

    Date of Rule: April 1, 1998.
    Reference: 62 FR 10140.
    In 1992, EPA promulgated federal regulations (The National Toxics 
Rule) establishing water quality criteria for toxic pollutants for 
several states, including Alaska (40 CFR 131.36). One of the toxic 
pollutants included in that rule was arsenic. In this final rule, EPA 
withdrew the applicability to Alaska's waters of the federal human 
health criteria for arsenic.

District of Columbia, Idaho, Kansas, Rhode Island, Vermont

    Date of Rule: April 12, 2000.
    Reference: 65 FR 19659.
    In 1992, EPA promulgated Federal regulations (the National Toxics 
Rule) establishing water quality criteria for toxic pollutants for 
several States, including Rhode Island, Vermont, the District of 
Columbia, Kansas and Idaho. These States have adopted, and EPA has 
approved, human health and aquatic life water quality criteria that are 
no less stringent than the Federal Criteria. Therefore, in this final 
rule, EPA amended the Federal regulations to withdraw certain human 
health and aquatic life criteria applicable to these States.

California

    Date of Rule: May 18, 2000.
    Reference: 65 FR 31681.
    This final rule promulgated: Numeric aquatic life criteria for 23 
priority toxic pollutants; numeric human health criteria for 57 
priority toxic pollutants; and a compliance schedule provision which 
authorizes the State to issue schedules of compliance for new or 
revised National Pollutant Discharge Elimination System permit limits 
based on the federal criteria when certain conditions are met.

[[Page 29962]]

    EPA promulgated this rule based on the Administrator's 
determination that numeric criteria are necessary in the State of 
California to protect human health and the environment. The Clean Water 
Act requires States to adopt numeric water quality criteria for 
priority toxic pollutants for which EPA has issued criteria guidance, 
the presence or discharge of which could reasonably be expected to 
interfere with maintaining designated uses.
    EPA promulgated this rule to fill a gap in California water quality 
standards that was created in 1994 when a State court overturned the 
State's water quality control plans which contained water quality 
criteria for priority toxic pollutants. Thus, the State of California 
was without numeric water quality criteria for many priority toxic 
pollutants as required by the Clean Water Act, necessitating this 
action by EPA. These Federal criteria are legally applicable in the 
State of California for inland surface waters, enclosed bays and 
estuaries for all purposes and programs under the Clean Water Act.

    Dated: May 27, 2001.
