Arizona's Integrated Report
On July 31, 2009, EPA partially approved and partially disapproved Arizona's 2006-2008 303(d) listing submission. EPA identified 23 additional waters and 5 additional pollutants for already-listed waters, for addition to Arizona's 2006-2008 303(d) list, dated November 2008. Documents describing EPA's review of the State's submittal and EPA's invitation for public comments for added waters are provided below. The public comment period closed on September 21, 2009.
EPA reviewed public comments received, and determined that the additional listings identified in the July 31, 2009 listing decision are appropriate. EPA’s letter of November 3, 2009 presents this final decision, and includes a responsiveness summary (summary of the comment received and EPA’s responses) and the additional waters and pollutants being added by EPA to Arizona’s 2006-2008 Section 303(3) list.

On May 29, 2008, EPA revised its previous decision to add microcystin toxins as an additional cause of impairment to one Klamath River segment (Middle Hydrologic Area: Oregon to Iron Gate) previously listed by California in its 2006 Clean Water Act Section 303(d) List. EPA solicited public comment on its action, and has now completed its review of the comments received. Based on comments from the North Coast Regional Board, EPA agreed to revise the description of the segment which EPA is listing as impaired due to “microcystin toxins.” EPA identified this impaired portion as “the reach of the Klamath River including the Copco and Iron Gate Reservoirs.” Accordingly, this segment does not include Klamath River upstream of Copco I Reservoir to Oregon.
- EPA’s May 2008 revised decision for microcystin toxins in Klamath River (PDF) (8 pp, 548K)
- EPA’s responsiveness summary (1 pg, 51K)
On March 13, 2008, EPA reconsidered its prior approval of the omission of microcystin toxins listings for three Klamath River segments, and determined to add a listing for microcystin toxin for one of these three segments, “Klamath River HU, Middle HA, Oregon to Iron Gate”. California’s 2006 Section 303(d) List already identifies each segment of the Klamath River within California as impaired due to Nutrients, Organic Enrichment/Low Dissolved Oxygen, and Temperature. EPA’s reconsideration of its decisions related to microcystin toxins and the Klamath River, and its determination to add a listing for microcystin toxins for one of the river’s segments, do not affect EPA’s determinations regarding any other portion of California’s Section 303(d) List. Neither EPA’s approval of the State’s listings for the Klamath River listings, nor EPA’s determination to add the listing for microcystin toxins, extends to any water bodies located within Indian country, as defined in 18 U.S.C. 1151.

On Nov. 30, 2006, EPA partially approved California's 2004-2006 303(d) list submission. In summary, this action approved the State's list of impaired waters. On March 8, 2007, EPA partially disapproved California's 2004-2006 303(d) List; that is, we disapproved the State's omission of impaired waters that met federal listing regulations or guidance. EPA identified 36 additional waters bodies and associated pollutants for 34 waters to be added to the State's 303(d) list. EPA provided public notice and the opportunity for public comment on our proposed additions which ended April 16, 2007.
On June 28, 2007, EPA issued its final decision regarding the waters we added to the State’s List. See final transmittal letter with enclosures and responsiveness summary below.
