Clean Water Act Section 303(d): Availability of List Decisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: This action announces the availability of EPA decisions 
identifying water quality limited segments and associated pollutants in 
Arizona to be listed pursuant to Clean Water Act section 303(d)(2), and 
requests public comment. Section 303(d)(2) requires that states submit 
and EPA approve or disapprove lists of waters for which existing 
technology-based pollution controls are not stringent enough to attain 
or maintain state water quality standards and for which total maximum 
daily loads (TMDLs) must be prepared.
    On July 31, 2009, EPA partially approved and partially disapproved 
Arizona's 2006-2008 submittal. Specifically, EPA approved Arizona's 
listing of 54 waters, associated pollutants, and associated priority 
rankings. EPA disapproved Arizona's decisions not to list 23 water 
quality limited segments and associated pollutants, and additional 
pollutants for 5 water bodies already listed by the State. EPA 
identified these additional water bodies and pollutants along with 
priority rankings for inclusion on the 2006-2008 section 303(d) list.
    EPA is providing the public the opportunity to review its decisions 
to add waters and pollutants to Arizona 2006-2008 section 303(d) list, 
as required by EPA's Public Participation regulations. EPA will 
consider public comments in reaching its final decisions on the 
additional water bodies and pollutants identified for inclusion on 
Arizona's final lists.

DATES: Comments must be submitted to EPA on or before September 21, 
2009.

ADDRESSES: Comments on the proposed decisions should be sent to Susan 
Keydel, Water Division (WTR-2), U.S. Environmental Protection Agency 
Region IX, 75 Hawthorne Street, San Francisco, CA 94105, telephone 
(415) 972-3106, facsimile (415) 947-3537, e-mail <a href="/cdn-cgi/l/email-protection#a5cec0dcc1c0c98bd6d0d6c4cbe5c0d5c48bc2cad3"><span class="__cf_email__" data-cfemail="1a717f637e7f7634696f697b745a7f6a7b347d756c">[email protected]</span></a>. 
Oral comments will not be considered. Copies of the proposed decisions 
concerning Arizona which explain the rationale for EPA's decisions can 
be obtained at EPA Region 9's Web site at http://www.epa.gov/region9/water/tmdl/303d.html or by writing or calling Ms. Keydel at the above 
address. Underlying documentation comprising the record for these 
decisions is available for public inspection at the above address.

SUPPLEMENTARY INFORMATION: Section 303(d) of the Clean Water Act (CWA) 
requires that each state identify those waters for which existing 
technology-based pollution controls are not stringent enough to attain 
or maintain state water quality standards. For those waters, states are 
required to establish TMDLs according to a priority ranking.
    EPA's Water Quality Planning and Management regulations include 
requirements related to the implementation of section 303(d) of the CWA 
[40 CFR 130.7]. The regulations require states to identify water 
quality limited waters still requiring TMDLs every two years. The lists 
of waters still needing TMDLs must also include priority rankings and 
must identify the waters targeted for TMDL development during the next 
two years [40 CFR 130.7].
    Consistent with EPA's regulations, Arizona submitted to EPA its 
listing decisions under section 303(d)(2), received on December 17, 
2008. On July 31, 2009, EPA approved Arizona's listing of 54 waters and 
associated priority rankings. EPA disapproved Arizona's decisions not 
to list 23 water quality limited segments and associated pollutants, 
and additional pollutants for 5 water bodies already listed by the 
State. EPA identified these additional waters and pollutants along with 
priority rankings for inclusion on the 2006-2008 section 303(d) list. 
EPA solicits public comment on its identification of additional waters 
and associated pollutants, and additional pollutants for waters already 
listed by the State, for inclusion on Arizona's 2006-2008 Section 
303(d) list.

    Dated: August 3, 2009.
Nancy Woo,
Associate Director, Water Division, Region IX.
