Environmental Protection Agency (EPA).
Notice of availability.
Region VIII of the EPA is hereby providing notice, and requesting public comment on EPA's decision to identify additional water quality limited segments and associated pollutants in Colorado to be listed pursuant to Clean Water Act section 303(d)(2). Section 303(d)(2) of the Clean Water Act 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 26, 2004, EPA partially approved and partially disapproved Colorado's section 303(d) list submittal for the 2004 listing cycle. Specifically, EPA approved Colorado's listing of 117 waters, associated pollutants, and associated priority rankings. EPA disapproved Colorado's decisions not to list six waterbodies and associated pollutants and one pollutant for a waterbody already listed by the State. EPA identified these additional water bodies and pollutants along with priority rankings for inclusion on the year 2004 section 303(d) list.
EPA is providing the public the opportunity to review its decisions to add waters and pollutants (shown in Table 1) to Colorado's 2004 section 303(d) list, as required by EPA's Public Participation regulations (40 CFR part 25). EPA will consider public comments in reaching its final decisions on the additional water bodies and pollutants identified for inclusion on Colorado's list.
Comments must be submitted to EPA on or before September 20, 2004.
Comments on the proposed decisions should be sent to Kathryn Hernandez, TMDL Team (8EPR-EP), U.S. Environmental Protection Agency Region VIII, 999 18th Street, Suite 300, Denver, CO 80202-2466, telephone (303) 312-6101, facsimile (303) 312-6339, e-mail firstname.lastname@example.org. Oral comments will not be considered. Copies of EPA's decision concerning Colorado's list that explain the rationale for EPA's decisions can be obtained at EPA Region VIII's Web site at http://www.epa.gov/region08/water/tmdl, or by writing or calling Ms. Hernandez at the above address. The full administrative record containing background technical information is on file and may be inspected at the U.S. EPA, Region VIII Technical Library found in the Environmental Information Service Center (EISC). The Library and Service Center are located on the ground floor at Denver Place, 999 18th Street, Denver Colorado. The Library is open to the public from 10 a.m. to 4 p.m. The Library can be contacted by calling the Service Center at (303) 312-6312 or (800) 227-8917. Arrangements to examine the administrative record may also be made by contacting Kathryn Hernandez.Start Further Info

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, identify the pollutants causing the impairment, and must identify the waters targeted for TMDL development during the next two years (40 CFR 130.7).
Consistent with EPA's regulations, Colorado submitted to EPA its listing decisions under section 303(d)(2) on March 18, 2004. On July 26, 2004, EPA approved Colorado's listing of 117 waters and associated priority rankings. EPA disapproved Colorado's decisions not to list six water quality limited segments and associated pollutants as well as one pollutant for a segment already on the State's list. EPA identified these additional waters and pollutants along with priority rankings for inclusion on the 2004 section 303(d) list. EPA solicits public comment on its identification of the additional waters, associated pollutants and priority rankings, for inclusion on Colorado's 2004 section 303(d) list.
