that allowing a significant lowering of water quality is necessary and accommodates important social or economic development in the area in which the waters are located.
(B) In allowing a significant lowering of water quality, the commissioner shall assure the following:
(i) Water quality adequate to fully protect existing uses is maintained.
(ii) The highest statutory and regulatory requirements for all new and existing point sources are applied.
(iii) Where authority exists, all cost-effective and reasonable BMPs for nonpoint source control are employed.
(3) For OSRWs, any new or increased loading of a regulated pollutant that results in a significant lowering of water quality for that regulated pollutant shall be prohibited, unless the:
(A) activity causing the increased loading:
(i) results in an overall improvement in water quality in the OSRW; and
(ii) meets the applicable requirements of this section; or
(B) person proposing the increased loading implements or funds a water quality improvement project in accordance with IC 13-18-3-2 in the watershed of the OSRW that:
(i) results in an overall improvement in water quality in the OSRW; and
(ii) meets the applicable requirements of this section.

(d) In addition to the OSRWs designated under IC 13-18-3-2(u) or listed at 327 IAC 2-1.5-19(b), the following waters are designated by the board to be OSRWs:

(1) These waters shall be maintained and protected in their present high quality without degradation except for short-term, temporary loadings as described in section 4(a) of this rule.
(2) To ensure the antidegradation standard under subdivision (1) is met, the following requirements apply:
(A) A deliberate activity that:
(i) is not exempt under section 4 of this rule; and
(ii) results in a new or increased loading;
is prohibited.
(B) A loading to a tributary of an ONRW that is not exempt under section 4 of this rule shall not be allowed if it would cause an increase in the ambient concentration of that pollutant in the ONRW.

(f) Except for ONRWs, any determination made by the commissioner in accordance with Section 316 of the CWA concerning alternative thermal effluent limitations shall be considered to be consistent with the antidegradation standards contained in this section.

Sec. 12.1. (a) When a permit issued to a new Great Lakes discharger contains a WQBEL, the permittee shall comply with such a limitation upon the commencement of the discharge.

(b) Any existing permit that is reissued or modified to contain a new or more restrictive WQBEL or a more restrictive limit of quantitation (LOQ) (when an LOQ is used as the compliance value for a WQBEL below an LOQ) may allow a reasonable period of time, up to five (5) years from the date of permit issuance or modification, for the permittee to comply with that limit in accordance with the following conditions:
(1) When the compliance schedule established under this subsection goes beyond the term of the permit, an interim permit limit effective upon the expiration date shall be included in the permit and addressed in the permit's fact sheet or statement of basis. The permit shall reflect the final limit and its compliance date.
(2) If a permit establishes a schedule of compliance under this subsection, which exceeds one (1) year from the date of permit issuance or modification, the schedule shall set forth interim requirements and dates for their achievement as follows:
(A) The time between such interim dates may not exceed one (1) year.
(B) If the time necessary for completion of any interim requirement is more than one (1) year and is not readily divisible into stages for completion, the permit shall require, at a minimum, specified dates for annual submission of progress reports on the status of any interim requirements.

(c) Whenever a limit based upon a Tier II value is included in a reissued or modified permit for an existing Great Lakes discharger, the permit may provide a reasonable period of time, up to two (2) years, in which to provide additional studies necessary to develop a Tier I criterion or to modify the Tier II value. In such cases, the permit shall require compliance with the Tier II limitation within a reasonable period of time, no not later than five (5) years after permit issuance or modification, and contain a reopener clause in accordance with the following conditions:
(1) The reopener clause shall authorize permit modifications if specified studies have been completed by the permittee or provided by a third party during the time allowed to conduct the specified studies, and the permittee or a third party demonstrates, through such studies, that a revised limit is appropriate. Such a revised limit shall be incorporated through a permit modification and a reasonable time period, up to five (5) years, shall be allowed for compliance. If incorporated prior to the compliance date of the original Tier II limitation, any such revised limit shall not be considered less stringent for purposes of the antibacksliding provisions of section 10(11) of this rule and Section 402(o) of the Clean Water Act (CWA).
(2) If the specified studies have been completed and do not demonstrate that a revised limit is appropriate, the commissioner may provide a reasonable additional period of time, not to exceed five (5) years with which to achieve compliance with the original effluent limitation.
(3) Where a permit is modified to include new or more stringent limitations, on a date within five (5) years of the permit expiration date, such compliance schedules may extend beyond the term of a permit consistent with subsection (b)(1).
(4) If future studies (other than those conducted under this subsection) result in a Tier II value being changed to a less stringent Tier II value or Tier I criterion, after the effective date of a Tier II-based limit, the existing Tier II-based limit may be revised to be less stringent if:
(A) it complies with section 10(11)(B) and 10(11)(C) of this rule and Section 402(o)(2) and 402(o)(3) of the CWA;
(B) in nonattainment waters, the cumulative effect of the revised effluent limitation will assure compliance with water quality standards; or
(C) in attained waters, the revised effluent limitation complies with the antidegradation standard and procedures contained under 327 IAC 2-1.5-4 and section 11.3 of this rule. 327 IAC 2-1.3.
