(i) The owner or operator may request an alternate means of control (AMOC) as follows:
  (1) Permitting Requirements. Compliance with this subsection does not relieve any owner or operator of the responsibility to comply with the requirements of §116.110 or §116.151 of this title (relating to Applicability and New Major Source or Major Modification in Nonattainment Area Other Than Ozone, respectively) with respect to the new construction or modification of sources that may emit SO2 into the air of this state.
  (2) Availability of AMOC.
    (A) The owner or operator of any site subject to a control requirement in this subchapter may request approval of an AMOC plan using the procedures established in this subsection. The executive director shall review a submitted AMOC and may approve the AMOC plan if it is demonstrated that the plan meets all applicable criteria and procedures of this subsection. The owner or operator who submits an AMOC plan not satisfying the requirements of this section may apply for a site-specific state implementation plan revision approved by the executive director and the United States Environmental Protection Agency (EPA).
    (B) Application for an AMOC plan does not stay enforcement of regulations in this subchapter.
    (C) Any violation of an AMOC plan will be subject to enforcement action as a violation of this subchapter.
  (3) Criteria for Approval of AMOC Plans. An AMOC plan may be approved if it meets each of the following criteria, as applicable.
    (A) Except as provided for in paragraph (8) of this subsection, all sources covered by the AMOC plan must be and remain at the same site.
    (B) If the AMOC plan includes an increase in the lb/hr emission limit for a source subject to the control requirements in this subchapter, the AMOC plan must also include an equivalent decrease in the lb/hr emission limit for one or more sources subject to the control requirements of this subchapter.
    (C) The AMOC application must include a demonstration that satisfies the following requirements.
      (i) The modeled impacts of all sources affected by the AMOC plan demonstrate no net increase in ground-level concentration, which for purposes of this subparagraph means no net increase in modeled off-property concentration of SO2, on a highest, first-high basis, at any receptor, i , in excess of the lesser of:
        (I) GLCcrit,i , as defined in the following equation; or

        (II) an applicable significant impact level for the one-hour National Ambient Air Quality Standard for SO2.
      (ii) Except where otherwise provided in this subsection, the demonstration required under this paragraph must be by means of applicable air quality models, databases, and other requirements specified in Appendix W to 40 CFR §51.1 and what was used in the modeling for the corresponding SIP revision.
    (D) The AMOC must be implemented and reductions created after the effective date of this rule.
    (E) The AMOC plan must establish control requirements and monitoring, testing, recordkeeping, and reporting requirements consistent with and no less stringent than the applicable requirements of this subchapter for all sources in the plan that render the proposed control requirements enforceable.
  (4) Procedures for AMOC Plan Submittal.
    (A) The owner or operator requesting an AMOC plan shall submit a proposed AMOC plan and demonstration to the executive director; copies of such plan and demonstration must also be submitted to the appropriate regional office, any local air pollution control program with jurisdiction over the site affected by the AMOC plan, and the EPA regional office.
    (B) The proposed AMOC plan must include the following information:
