9.5 Definitions

1. A. Unless otherwise expressly defined in this section, the terms used in this regulation shall be defined by reference to Part 0 of this Subchapter (General Definitions). As used in this regulation, the following terms shall, where the context permits, be construed as follows:

   1. 1. "Actual emissions" means the actual rate of emissions of a pollutant from an emissions unit, as determined in accordance with §§ 9.5(A)(1)(a) through (c) of this Part below:

      1. a. In general, actual emissions as of a particular date shall equal the average rate, in tons per year, at which the unit actually emitted the pollutant during a two-year period which precedes the particular date and which is representative of normal source operation. The Director shall allow the use of a different time period upon a determination that it is more representative of normal source operation. Actual emissions shall be calculated using the unit's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period.
      2. b. The Director may presume that source specific allowable emissions for the unit are equivalent to actual emissions of the unit.
      3. c. For any emissions unit which has not begun normal operations on the particular date, actual emissions shall equal the potential to emit of the unit on that date.

   2. 2. "Allowable emissions" means the emission rate of a stationary source calculated using the maximum rated capacity of the source unless the source is subject to federally enforceable limits which restrict the operating rate or hours of operation, or both and the most stringent of the following:

      1. a. Applicable standards as set forth in New Source Performance Standards, 40 C.F.R. § 60 (2018) and National Emission Standards for Hazardous Air Pollutants, 40 C.F.R. § 61 (2018); or
      2. b. Any applicable State Implementation Plan emission limitations, including those with a future compliance date; or
      3. c. The emissions rate specified as a federally enforceable permit condition, including those with a future compliance date.
   3. 3. "Attainment area” or “Unclassifiable area" means for any air pollutant, an area which is not designated as a nonattainment area.

   4. 4. "Baseline actual emissions" means the rate of emissions, in tons per year, of a regulated New Source Review (NSR) pollutant, as determined in accordance with this definition.

      1. a. For any existing emissions unit, baseline actual emissions means the average rate, in tons per year, at which the unit actually emitted the pollutant during the two consecutive calendar years immediately prior to the year a complete permit application is received by the Department. The Department may allow the use of a different 24-month period within the last five (5) years upon a determination that it is more representative of normal source operation.

         1. (1) The average rate shall include fugitive emissions to the extent quantifiable and any authorized emissions associated with startup and shutdown. The average rate shall not include excess emissions or emissions associated with upsets or malfunctions.
         2. (2) The average rate shall be adjusted downward to exclude any non-compliant emissions that occurred while the source was operating above an emission limitation that was legally enforceable during the consecutive 24-month period.
         3. (3) The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must currently comply, had such major stationary source been required to comply with such limitations during the consecutive 24-month period.
         4. (4) When a project involves multiple emissions units or multiple regulated NSR pollutants, or both, only one consecutive 24-month period must be used to determine the baseline actual emissions for all pollutants and all emission units affected by the project.
         5. (5) The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required by §§ 9.5(A)(4)(a)((2)) and ((3)) of this Part, in this definition.
      2. b. For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of such unit shall equal zero.
   5. 5. "Begin actual construction" means, in general, initiation of physical onsite construction activities on an emissions unit which are of a permanent nature. Such activities include, but are not limited to, installing building supports and foundations, laying underground pipework, and constructing permanent storage structures. With respect to a change in the method of operation, this term refers to those on-site activities, other than preparatory activities, which mark the initiation of the change.
   6. 6. "Calculated acceptable ambient level" means the maximum allowable air concentration of an air contaminant, excluding listed toxic air contaminants and national ambient air quality standards, contributed by a stationary source, at or beyond the facility's property line calculated by the method in the Rhode Island Air Toxics Guideline.

   7. 7. "Commence" means as applied to construction of a stationary source or modification means that the owner or operator has all the necessary preconstruction approvals or permits and either has:

      1. a. Begun or caused to begin, a continuous program of actual on-site construction of the source, to be completed within a reasonable time; or
      2. b. Entered into binding agreements or contractual obligations, which cannot be canceled or modified without substantial loss to the owner or operator, to undertake a program of actual construction of the source to be completed within a reasonable time.
   8. 8. "Complete" means in reference to an application for a permit, that the application contains all the information necessary for processing the application. Designating an application complete for purposes of permit processing does not preclude the Director from requesting or accepting any additional information.

   9. 9. "Construct a 42 U.S.C. § 7412(g), (CAA § 112(g)) source" means:

      1. a. To fabricate, erect, or install at any greenfield site an emissions unit or group of emissions units which is located within a contiguous area and under common control and which emits or has the potential to emit ten (10) tons per year of any Hazardous Air Pollutant (HAP) or twenty-five (25) tons per year of any combination of HAP, or

      2. b. To fabricate, erect, or install at any developed site an emissions unit which in and of itself emits or has the potential to emit ten (10) tons per year of any HAP or twenty-five (25) tons per year of any combination of HAP, unless the emissions unit satisfies criteria in §§ 9.5(A)(9)(b)((1)) through ((6)) of this Part, in this definition.

         1. (1) All HAP emitted by the emissions unit that would otherwise be controlled under the requirements of this subpart will be controlled by emission control equipment which was previously installed at the same site as the emissions unit;

(2) The Office of Air Resources has determined within a period of 5 years prior to the fabrication, erection, or installation of the emissions unit that the existing emission control equipment represented best available control technology (BACT) or lowest achievable emission rate (LAER); or the Office of Air Resources determines that the control of HAP emissions provided by the existing equipment will be equivalent to that level of control currently achieved by other well-controlled similar sources (i.e., equivalent to the level of control that would be provided by a current BACT or LAER;
         3. (3) The Office of Air Resources determines that the percent control efficiency for emissions of HAP from all sources to be controlled by the existing control equipment will be equivalent to the percent control efficiency provided by the control equipment prior to the inclusion of the new emissions unit;
         4. (4) The Office of Air Resources has provided notice and an opportunity for public comment concerning its determination that criteria in paragraphs §§ 9.5(A)(9)(b)((1)) through ((3)) of this Part, in this definition apply and concerning the continued adequacy of any prior BACT or LAER determination;
         5. (5) If any commenter has asserted that a prior BACT or LAER determination is no longer adequate, the Office of Air Resources has determined that the level of control required by that prior determination remains adequate; and
         6. (6) Any emission limitations, work practice requirements, or other terms and conditions upon which the above determinations by the Office of Air Resources were made, are applicable requirements under "Air Pollution Control Regulation No. 29 - Operating Permits" and either have been incorporated into any existing operating permit for the affected facility or will be incorporated into such permit upon issuance.

Except that:

       1. a. Greenhouse gases (GHGs), the air pollutant defined in 40 C.F.R. § 86.1818–12(a) (2018) as the aggregate group of six (6) greenhouse gases: Carbon dioxide, nitrous oxide, methane, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride, shall not be subject to regulation except as provided in § 9.5(A)(41)(d) of this Part.

2. B. New major stationary sources or major modifications of sulfur dioxide, nitrogen dioxide, carbon monoxide or PM-10, proposed in areas designated as nonattainment pursuant to 42 U.S.C. § 7407 (2018), (CAA § 107(d)) for the pollutant for which the source or modification is major, must obtain a major source permit. The following conditions must be met for the issuance of a major source permit:

   1. 1. Except as provided in §§ 9.8.1(B)(1)(c) through (d) of this Part, the source must meet an emission limitation that is considered the lowest achievable emission rate. This lowest achievable emission rate will be based on technological factors and can be in the form of a numerical emission standard or a design, operational or equipment standard.

      1. a. A new major stationary source shall apply the lowest achievable emission rate for each pollutant subject to the provisions of § 9.8.1 of this Part that it would have the potential to emit in major amounts. This provision applies to each new emissions unit at which emissions would occur.
      2. b. The owner or operator of a source proposing a major modification shall apply the lowest achievable emission rate for each pollutant subject to the provisions of § 9.8.1 of this Part for which it would result in a significant net emissions increase at the source. This requirement applies to each proposed emissions unit at which a net emissions increase in the pollutant would occur as a result of a physical change or change in the method of operation of the unit.
      3. c. For applications for major modifications to a stationary source which has potential emissions equal to or greater than fifty (50) tons per year but less than one hundred (100) tons per year of volatile organic compounds or nitrogen oxides the source must apply BACT instead of LAER.
      4. d. For applications for major modifications to a stationary source which has potential emissions greater than one hundred (100) tons per year of volatile organic compounds or nitrogen oxides the source must meet an emission limitation considered the lowest achievable emission rate unless internal offsets of such volatile organic compounds or nitrogen oxides are obtained at a ratio of at least 1.3 to 1, the source must then apply BACT instead of LAER.
   2. 2. The applicant must certify that all existing major stationary sources owned or operated by the applicant (or any entity controlling, controlled by, or under common control with the applicant) located within the state are in compliance with all applicable state and federal air pollution rules and regulations under the Clean Air Act and federally enforceable compliance schedules.
   3. 3. The applicant must provide evidence in accordance with § 9.8.2 of this Part that the total tonnage of emissions of the applicable nonattainment air pollutant allowed from the proposed new source or net emissions increase from the modification, shall be offset by a greater reduction in the actual emissions of such air pollutant from the same or other sources.

   4. 4. The emission offsets must:

      1. a. Be approved by the Director, and be part of a federally enforceable permit, or part of an operating permit issued pursuant to 40 C.F.R. § 71 (2018) or under regulations approved pursuant to 40 C.F.R. § 70 (2018), or otherwise made part of the federally approved State Implementation Plan.
      2. b. Be federally enforceable prior to the issuance of the major source permit.

   9. 9. The applicant must demonstrate that the stationary source will be in compliance with all applicable state or federal air pollution control rules or regulations at the time the stationary source or modification commences operation.

      9.8.2 Emission Offset Demonstration

3. A. Credit for an emissions reduction may be claimed to the extent that such reduction has not been relied on in any permit already issued under 40 C.F.R. §§ 52 or 71 (2018) or regulations approved pursuant to 40 C.F.R. §§ 51 or 70 (2018) or the state has not relied on it in demonstrating attainment or reasonable further progress. Incidental emissions reductions which are not otherwise required under the Clean Air Act may be creditable as emissions reductions for such purposes if such emissions reductions meet the applicable requirements for emission offsets. Emission offsets can be achieved by reducing current actual emissions of a source to a point below the applicable emission limitations in effect at the time of submission of the application by:

   1. 1. Installing additional air pollution control equipment on an existing source currently operating but considered in compliance with regulations.
   2. 2. Initiating a process change that will result in a reduction of emissions.
   3. 3. Applying fugitive emission control measures that reduce actual emissions to less than is allowed by the applicable emission limitations in effect at the time of application.

   4. 4. Switching to a different type of fuel that will result in lowering the emission rate below the emission rate in effect at the time of application, if the applicant can demonstrate that:

      1. a. an adequate long-term supply of the new fuel is available; and
      2. b. the use of a specified alternative air pollution control measure would achieve the same degree of emission control in the event the source should switch back to the original fuel at a later date.
   5. 5. Permanently curtailing production or operating hours below levels that are specified in a federally enforceable document issued by the Department, subject to the restrictions provided in § 9.8.2(C) of this Part.
   6. 6. Permanently shutting down a facility, process or a source of emissions, subject to the restrictions provided in § 9.8.2(C) of this Part.
   7. 7. Establishing and supporting employer business travel control measures or employee commuter travel control measures that have quantifiable emission reductions that must be enforceable, permanent and surplus.
   8. 8. Adopting any other measures that can be used for emission offsets that have been approved by the Director.

4. B. Offset credit will not be given for the following:

   1. 1. Emission reductions that result from complying with existing or new rules and regulations, New Source Performance Standards, and National Emission Standards for Hazardous Air Pollutants or emission reductions otherwise required by, 42 U.S.C. § 7401, et seq. (2018).
   2. 2. Increasing the stack height of a stationary source beyond good engineering practice as defined by the U.S. Environmental Protection Agency.
   3. 3. The reduction of different pollutants, e.g. an increase in NO₂ emissions cannot be offset by a reduction of SO₂ emissions.
   4. 4. With respect to a proposed increase in VOC emissions, no offset credit shall be allowed for reductions in any organic compound specifically excluded from the definition of "VOC" in Part 0 of this Subchapter (General Definitions).
   5. 5. Reductions of volatile organic compound emissions from November 1 to March 31 of any year to substitute for emission increases that occur during the rest of the year.
   6. 6. Emission reductions that occurred prior to January 1, 1990.

5. C. Emissions reductions achieved by shutting down an existing source or curtailing production or operating hours below baseline levels may be credited provided that:

   1. 1. Such reductions are surplus, permanent, quantifiable and federally enforceable; and,
   2. 2. The state has an EPA approved attainment plan for the area. The emissions reductions achieved from a shutdown or curtailment may be credited in the absence of an approved attainment plan only if the shutdown or curtailment occurred on or after the date the new source permit application is filed or if the proposed new source is a replacement for the shutdown or curtailed source and if the shutdown or curtailment and if the shutdown or curtailment occurred after January 1, 1990, or the date of the most recent emissions inventory used in the plan's demonstration of attainment, whichever is later.

   3. 3. The shutdown or curtailment occurred after January 1, 1990, or the date of the most recent emissions inventory used in the State's attainment plan, whichever is later. The Director may choose to consider a prior shutdown or curtailment to have occurred after the applicable date, if the most recent emissions inventory explicitly includes as current existing emissions, the emissions from such previously shutdown or curtailed sources.

      9.8.3 Reasonable Further Progress

6. A. By the time the proposed major stationary source or major modification is to commence operation, sufficient offsetting emissions shall be in effect such that the total emissions from existing sources in the area, from new or modified sources which are not major stationary sources and from the proposed source will be sufficiently less than total emissions from existing sources prior to the application for the major source permit so as to represent (when considered together with the plan provisions required under U.S.C § 7502 (2018), (CAA § 172) reasonable further progress.

7. B. For the purposes of satisfying the requirements of this paragraph, the determination of total emissions at both the time prior to the application for a major source permit and the time the such permitted source or modification would commence operation, shall be made in a manner consistent with the assumptions in the RI State Implementation Plan approved by the EPA concerning baseline emissions for the demonstration of reasonable further progress and the attainment of the national ambient air quality standard for the particular pollutant subject to review under § 9.8.1 of this Part.

   9.8.4 General Prohibition

8. The Director shall not issue a major source permit pursuant to the provisions of § 9.8 of this Part if the Administrator of the Environmental Protection Agency has determined that the State Implementation Plan is not being adequately implemented for the nonattainment area in which the proposed source or modification is to be constructed.
