CHAPTER 116CONTROL OF AIR POLLUTION BY PERMITS FOR NEW CONSTRUCTION OR MODIFICATION
SUBCHAPTER BNEW SOURCE REVIEW PERMITS
DIVISION 1PERMIT APPLICATION
RULE §116.116Changes to Facilities

(a) Representations and conditions. The following are the conditions upon which a permit, special permit, or special exemption are issued:

  (1) representations with regard to construction plans and operation procedures in an application for a permit, special permit, or special exemption; and

  (2) any general and special conditions attached to the permit, special permit, or special exemption itself.

(b) Permit amendments.

  (1) Except as provided in subsection (e) of this section, the permit holder shall not vary from any representation or permit condition without obtaining a permit amendment if the change will cause:

    (A) a change in the method of control of emissions;

    (B) a change in the character of the emissions; or

    (C) an increase in the emission rate of any air contaminant.

  (2) Any person who requests permit amendments must receive prior approval by the executive director or the commission. Applications must be submitted with a completed Form PI-1 and are subject to the requirements of §116.111 of this title (relating to General Application).

  (3) Any person who applies for an amendment to a permit to construct or reconstruct an affected source (as defined in §116.15(1) of this title (relating to Section 112(g) Definitions)) under Subchapter E of this chapter (relating to Hazardous Air Pollutants: Regulations Governing Constructed or Reconstructed Major Sources (FCAA, §112(g), 40 CFR Part 63)) shall comply with the provisions in Chapter 39 of this title (relating to Public Notice).

  (4) Any person who applies for an amendment to a permit to construct a new facility or modify an existing facility shall comply with the provisions in Chapter 39 of this title.

(c) Permit alteration.

  (1) A permit alteration is:

    (A) a decrease in allowable emissions; or

    (B) any change from a representation in an application, general condition, or special condition in a permit that does not cause:

      (i) a change in the method of control of emissions;

      (ii) a change in the character of emissions; or

      (iii) an increase in the emission rate of any air contaminant.

  (2) Requests for permit alterations that must receive prior approval by the executive director are those that:

    (A) result in an increase in off-property concentrations of air contaminants;

    (B) involve a change in permit conditions; or

    (C) affect facility or control equipment performance.

  (3) The executive director shall be notified in writing of all other permit alterations not specified in paragraph (2) of this subsection.

  (4) A request for permit alteration shall include information sufficient to demonstrate that the change does not interfere with the owner or operator's previous demonstrations of compliance with the requirements of §116.111(a)(2)(C) of this title.

  (5) Permit alterations are not subject to the requirements of §116.111(a)(2)(C) of this title.

(d) Permits by rule under Chapter 106 of this title (relating to Permits by Rule) in lieu of permit amendment or alteration.

  (1) A permit amendment or alteration is not required if the changes to the permitted facility qualify for an exemption from permitting or permit by rule under Chapter 106 of this title unless prohibited by permit condition as provided in §116.115 of this title (relating to General and Special Conditions).

  (2) All changes authorized under Chapter 106 of this title to a permitted facility shall be incorporated into that facility's permit when the permit is amended or renewed.

(e) Changes to qualified facilities.

  (1) Prior to determining if this subsection may be applied to a proposed change to a facility, the following will apply:

    (A) The facility must be authorized under this chapter or Chapter 106 of this title.

    (B) A separate netting analysis shall be made for each proposed change to determine the applicability of major New Source Review by demonstrating that any increase in actual emissions is below the threshold for major modification as defined in §116.12 of this title (relating to Nonattainment and Prevention of Significant Deterioration Review Definitions). Proposed changes exceeding the major modification threshold cannot be authorized under this subsection. This analysis shall meet the definition and requirements of net emissions increase in §116.12 of this title.

  (2) Prior to changes under this subsection, facility owners or operators will submit Form PI-E, Notification of Changes to Qualified Facilities, and the following additional requirements will apply:

    (A) Facility owners or operators will simultaneously submit, where applicable, an application for a permit revision for each permit issued under §116.111 of this title involved in the qualified facility transaction.

    (B) Owners or operators of facilities authorized under Subchapter F of this Chapter, (relating to Standard Permits) shall submit a revision to the representations in the facility registration in accordance with §116.611 of this title (relating to Registration to Use a Standard Permit).

    (C) Any applicable permit issued under §116.111 of this title will be revised to reflect changes under this subsection to facilities authorized under Chapter 106 of this title. If no applicable permit issued under §116.111 of this title is involved in the qualified facility transaction then changes shall be certified by a registration for an emission rate under §106.6 of this title (relating to Registration of Emissions).

    (D) No allowable emission rate as defined in §116.17 of this title (relating to Qualified Facilities Definitions) shall be exceeded.

    (E) The facility has received a preconstruction permit or permit amendment no earlier than 120 months before the change will occur, or uses control technology that is at least as effective as the BACT that the commission required or would have required for a facility of the same class or type as a condition of issuing a permit or permit amendment 120 months before the change will occur. There will be no reduction in emission control efficiency.

  (3) Notwithstanding any other subsection of this section, a physical or operational change may be made to a qualified facility if it can be determined that the change does not result in:

    (A) a net increase in allowable emissions of any air contaminant; and

    (B) the emission of any air contaminant not previously emitted.

  (4) In making the determination in paragraph (3) of this subsection, the effect on emissions of the following shall be considered:

    (A) any air pollution control method applied to the qualified facility;

    (B) any decreases in allowable emissions from other qualified facilities at the same commission air quality account that have received a preconstruction permit or permit amendment no earlier than 120 months before the change will occur; and

    (C) any decrease in actual emissions from other qualified facilities at the same commission air quality account that are not included in subparagraph (B) of this paragraph.

  (5) The determination in paragraph (3) of this subsection shall be based on the allowable emissions for air contaminant categories and any allowable emissions for individual compounds. If a physical or operational change would result in emissions of an air contaminant category or compound above the allowable emissions for that air contaminant category or compound, there must be an equivalent decrease in emissions at the same facility or a different facility at the same account.

    (A) The equivalent decrease in emissions shall be based on the same time periods (e.g., hourly and 12-month rolling average rates) as the allowable emissions for the facility at which the change will occur.

    (B) Emissions of different compounds within the same air contaminant category may be interchanged. Emissions of substances that were, but are not currently, listed as a volatile organic compound (VOC) by the United States Environmental Protection Agency (EPA) may be substituted for emissions of compounds currently listed by EPA as a VOC as referenced in §101.1 of this title (relating to Definitions) provided the compound being used as a substitute is not regulated as a hazardous air pollutant and is not toxic. The substitution of current VOCs for compounds that have been removed from the VOC list by EPA is prohibited.

    (C) For allowable emissions for individual compounds, any interchange shall adjust the emission rates for the different compounds in accordance with the ratio of the effects screening levels of the compounds. The effects screening level shall be determined by the executive director.

    (D) For allowable emissions for air contaminant categories, interchanges shall use the unadjusted emission rates for the different compounds.

    (E) The facility owner or operator shall demonstrate that the change will not adversely affect ambient air quality.

    (F) An air contaminant category is a group of related compounds, such as volatile organic compounds, particulate matter, nitrogen oxides, and sulfur compounds.

  (6) Persons making changes to qualified facilities under this subsection shall comply with the applicable requirements of §116.117 of this title (relating to Documentation and Notification of Changes to Qualified Facilities).

  (7) As used in this subsection, the term "physical and operational change" does not include:

    (A) construction of a new facility; or

    (B) changes to procedures regarding monitoring, determination of emissions, and recordkeeping that are required by a permit.

  (8) Additional air pollution control methods may be implemented for the purpose of making a facility a qualified facility. The implementation of any additional control methods to qualify a facility shall be subject to the requirements of this chapter. The owner or operator shall:

    (A) utilize additional control methods that are as effective as best available control technology (BACT) required at the time the additional control methods are implemented; or

    (B) demonstrate that the additional control methods, although not as effective as BACT, were implemented to comply with a law, rule, order, permit, or implemented to resolve a documented citizen complaint.

  (9) For purposes of this subsection and §116.117 of this title, the following subparagraphs apply.

    (A) Intraplant trading means the consideration of decreases in allowable and actual emissions from other qualified facilities in accordance with paragraph (4) of this subsection.

    (B) The allowable emissions from facilities that were never constructed shall not be used in intraplant trading.

    (C) The decreases in allowable and actual emissions shall be based on emission rates for the same time periods (e.g., hourly and 12-month rolling average) as the allowable emissions for the facility at which the change will occur and for which an intraplant trade is desired.

    (D) Actual emissions shall be based on data that is representative of the emissions actually achieved from a facility during the relevant time period (e.g., hourly or 12-month rolling average).

  (10) The existing level of control may not be lessened for a qualified facility.

  (11) A separate netting analysis shall be performed for each proposed change under this subsection.

(f) Use of credits. Notwithstanding any other subsection of this section, discrete emission reduction credits may be used to exceed permit allowables as described in §101.376(b) of this title (relating to Discrete Emission Credit Use) if all applicable conditions of §101.376 of this title are met. This subsection does not authorize any physical changes to a facility.
