    (3) Procedures for site specific modification of listed waterbodies 
or temperature criteria for bull trout.

[[Page 387]]

    (i) The Regional Administrator may, in his discretion, determine 
that the temperature criteria in paragraph (a)(1) of this section shall 
not apply to a specific waterbody or portion thereof listed in paragraph 
(a)(2) of this section. Any such determination shall be made consistent 
with Sec. 131.11 and shall be based on a finding that bull trout 
spawning and rearing is not an existing use in such waterbody or portion 
thereof.
    (ii) The Regional Administrator may, in his discretion, raise the 
temperature criteria in paragraph (a)(1) of this section as they pertain 
to a specific waterbody or portion thereof listed in paragraph (a)(2) of 
this section. Any such determination shall be made consistent with 
Sec. 131.11, and shall be based on a finding that bull trout would be 
fully supported at the higher temperature criteria.
    (iii) For any determination made under paragraphs (a)(3)(i) or 
(a)(3)(ii) of this section, the Regional Administrator shall, prior to 
making such a determination, provide for public notice of and comment on 
a proposed determination. For any such proposed determination, the 
Regional Administrator shall prepare and make available to the public a 
technical support document addressing each waterbody or portion thereof 
that would be deleted or modified and the justification for each 
proposed determination. This document shall be made available to the 
public not later than the date of public notice.
    (iv) The Regional Administrator shall maintain and make available to 
the public an updated list of determinations made pursuant to paragraphs 
(a)(3)(i) and (a)(3)(ii) of this section as well as the technical 
support documents for each determination.
    (v) Nothing in this paragraph (a)(3) shall limit the Administrator's 
authority to modify the temperature criteria in paragraph (a)(1) of this 
section or the list of waterbodies in paragraph (a)(2) of this section 
through rulemaking.
    (b) Use designations for surface waters. In addition to the State 
adopted use designations, the following water body segments in Idaho are 
designated for cold water biota: Canyon Creek (PB 121)--below mining 
impact; South Fork Coeur d'Alene River (PB 140S)--Daisy Gulch to mouth; 
Blackfoot River (USB 360)--Equalizing Dam to mouth, except for any 
portion in Indian country; Soda Creek (BB 310)--source to mouth.
    (c) Excluded waters. Lakes, ponds, pools, streams, and springs 
outside public lands but located wholly and entirely upon a person's 
land are not protected specifically or generally for any beneficial use, 
unless such waters are designated in Idaho 16.01.02.110. through 160., 
or, although not so designated, are waters of the United States as 
defined at 40 CFR 122.2.
    (d) Water quality standard variances. (1) The Regional 
Administrator, EPA Region X, is authorized to grant variances from the 
water quality standards in paragraph (b) of this section where the 
requirements of this paragraph (d) are met. A water quality standard 
variance applies only to the permittee requesting the variance and only 
to the pollutant or pollutants specified in the variance; the underlying 
water quality standard otherwise remains in effect.
    (2) A water quality standard variance shall not be granted if:
    (i) Standards will be attained by implementing effluent limitations 
required under sections 301(b) and 306 of the CWA and by the permittee 
implementing reasonable best management practices for nonpoint source 
control; or
    (ii) The variance would likely jeopardize the continued existence of 
any threatened or endangered species listed under section 4 of the 
Endangered Species Act or result in the destruction or adverse 
modification of such species' critical habitat.
    (3) Subject to paragraph (d)(2) of this section, a water quality 
standards variance may be granted if the applicant demonstrates to EPA 
that attaining the water quality standard is not feasible because:
    (i) Naturally occurring pollutant concentrations prevent the 
attainment of the use; or
    (ii) Natural, ephemeral, intermittent or low flow conditions or 
water levels

[[Page 388]]

prevent the attainment of the use, unless these conditions may be 
compensated for by the discharge of sufficient volume of effluent 
discharges without violating State water conservation requirements to 
enable uses to be met; or
    (iii) Human caused conditions or sources of pollution prevent the 
attainment of the use and cannot be remedied or would cause more 
environmental damage to correct than to leave in place; or
    (iv) Dams, diversions or other types of hydrologic modifications 
preclude the attainment of the use, and it is not feasible to restore 
the waterbody to its original condition or to operate such modification 
in a way which would result in the attainment of the use; or
    (v) Physical conditions related to the natural features of the 
waterbody, such as the lack of a proper substrate, cover, flow, depth, 
pools, riffles, and the like unrelated to water quality, preclude 
attainment of aquatic life protection uses; or
    (vi) Controls more stringent than those required by sections 301(b) 
and 306 of the CWA would result in substantial and widespread economic 
and social impact.
    (4) Procedures. An applicant for a water quality standards variance 
shall submit a request to the Regional Administrator not later than the 
date the applicant applies for an NPDES permit which would implement the 
variance, except that an application may be filed later if the need for 
the variance arises or the data supporting the variance becomes 
available after the NPDES permit application is filed. The application 
shall include all relevant information showing that the requirements for 
a variance have been satisfied. The burden is on the applicant to 
demonstrate to EPA's satisfaction that the designated use is 
unattainable for one of the reasons specified in paragraph (d)(3) of 
this section. If the Regional Administrator preliminarily determines 
that grounds exist for granting a variance, he shall publish notice of 
the proposed variance. Notice of a final decision to grant a variance 
shall also be published. EPA will incorporate into the permittee's NPDES 
permit all conditions needed to implement the variance.
    (5) A variance may not exceed 5 years or the term of the NPDES 
permit, whichever is less. A variance may be renewed if the applicant 
reapplies and demonstrates that the use in question is still not 
attainable. Renewal of the variance may be denied if the applicant did 
not comply with the conditions of the original variance.
