PROPOSED CHANGES TO IDAHO’S LIST OF IMPAIRED WATERS


UNITED STATES ENVIRONMENTAL PROTECTION AGENCY

Boise, Idaho 83706
NOTICE OF PROPOSED CHANGES TO
IDAHO’S LIST OF IMPAIRED WATERS


Public Notice Issuance Date: May 8, 2000
Public Notice Expiration Date: June 8, 2000

What is Proposed:
The United States Environmental Protection Agency, Region 10 (EPA) is proposing to add waters to Idaho’s list of impaired waters pursuant to Clean Water Act (CWA) Section 303(d), 33USC 1313(d).
CWA Section 303(d)
Section 303(d) of the CWA directs States to identify those waters within its jurisdiction for which effluent limitations required by Section 301(b)(1)(A) and (B) are not stringent enough to implement any applicable water quality standard, and to establish a priority ranking for such waters, taking into account the severity of the pollution and the uses to be made of such waters. The Section 303(d) listing requirement applies to waters impaired by point and/or nonpoint sources, pursuant to EPA’s long-standing interpretation of Section 303(d).

EPA regulations provide that States do not need to list waters where the following controls are adequate to implement applicable standards: (1) technology-based effluent limitations required by the CWA, (2) more stringent effluent limitations required by State or local authority, and (3) other pollution control requirements required by State, local, or Federal authority. (See 40 CFR 130.7(b)(1).)

EPA received Idaho’s CWA Section 303(d) list on January 4, 1999 and reviewed the list and accompanying materials in their list package. On April 27, 2000 EPA notified the Idaho Division of Environmental Quality (IDEQ) of EPA’s action to:
  1. approve IDEQs decision to include each of the waters designated by the State in its 1998 list, except that EPA took no action regarding waters within Indian Country, and
  2. disapprove the State’s decision not to include certain additional water body/parameter listings.

EPA is required under CWA Section 303(d) to issue a public notice to seek comments on its proposed changes to Idaho’s 1998 Section 303(d) list. By this notice, EPA proposes for public review and comment the addition of 134 water bodies for temperature and two (2) waterbodies for miscellaneous pollutants to Idaho’s 1998 Section 303(d) list. Of the 136 water bodies added, 44 are water bodies are already included in the State’s 1998 303(d) list but for different pollutants. The remaining 92 water bodies are not currently included on the State’s 1998 303(d) list.

Categories of waters proposed to be added:

Proposed listings fall into one of the following categories:
  1. those waters (134) that EPA believes were inappropriately excluded from the State’s 1998 list because temperature data available to the State indicates that applicable temperature criteria have been exceeded; and
  2. those waters (2) which were included in IDEQ’s 1996 list but were not included in the 1998 list, and EPA believes there is not an adequate basis to conclude that water quality standards are now being met.
