    (n) A water body may be designated as an outstanding national resource water only by the general assembly after recommendations for designation are made by the board and the environmental quality service council.
    (o) Before recommending the designation of an outstanding national resource water, the department shall provide for an adequate public notice and comment period regarding the designation. The commissioner shall present a summary of the comments and information received during the comment period and the

    (p) This subsection applies to all surface waters of the state. The department shall complete an antidegradation review of all NPDES general permits. The department may modify the general permits for purposes of antidegradation compliance. After an antidegradation review of a permit is conducted under this subsection, activities covered by an NPDES general permit are not required to undergo an additional antidegradation review. An NPDES general permit may not be used to authorize a discharge into an outstanding national resource water or an outstanding state resource water, except that a short term, temporary storm water discharge to an outstanding national resource water or to an outstanding state resource water may be permitted under an NPDES general permit if the commissioner determines that the discharge will not significantly lower the water quality downstream of the discharge.

    (s) Subject to subsection (t), the commissioner shall consider the following factors in determining whether a proposed discharge is necessary to accommodate important economic or social development in the area in which the waters are located under antidegradation standards and implementation procedures:
        (1) Creation, expansion, or maintenance of employment.
        (2) The unemployment rate.
        (3) The median household income.

            (A) recognizes social or economic importance; and
            (B) is given to the applicant by:
                (i) a legislative body; or
                (ii) other government officials.

        (18) Any other action or recommendation relevant to the antidegradation demonstration received during the public participation process.
        (19) Any other factors that the commissioner:
            (A) finds relevant; or
            (B) is required to consider under the Clean Water Act.
    (t) In determining whether a proposed discharge is necessary to accommodate important economic or social development in the area in which the waters are located under antidegradation standards and implementation procedures, the commissioner:
        (1) must give substantial weight to any applicable determinations by governmental entities; and
        (2) may rely on consideration of any one (1) or a combination of the factors listed in subsection (s).

        (2) At all times other than those described in subdivision (1), the water quality criteria associated with the appropriate recreational use designation that applied to the waters immediately before the application to the waters of the CSO wet weather limited use subcategory apply unless there is a change in the use designation as a result of a use attainability analysis.
    (b) The CSO wet weather limited use subcategory applies if:
        (1) the department has approved a long term control plan for the NPDES permit holder for the combined sewer system;

    (f) In conjunction with a review of its long term control plan under section 2.4 of this chapter, the NPDES permit holder shall review information generated after the use attainability analysis was approved by the department to determine whether the conclusion of the use attainability analysis is still valid. The NPDES permit holder

shall provide the results of the review to the department.

    (c) The department shall, at the request of the NPDES permit holder, incorporate in the permit a schedule of compliance for meeting the water quality based requirements associated with combined sewer overflows during the period of development, approval, and implementation of the long term control plan. The schedules of compliance:
        (1) may exceed time frames authorized under 327 IAC; and
        (2) may not exceed the period specified for implementation in an approved long term control plan.
