As required by 40 CFR Part 51, Subpart I - Review of New Sources and ~\odifications, this 

rule adopts criteria and procedures for the prevention of significant deterioration of 

air quality that are consistent with the governing federal regulation at 40 CFR §51.166. 

Promulgation of this rule by the Legislature is necessary for the State to fulfill its 

responsibilities under 40 CFR Part 51 and the CAA, as amended. 

Revisions to the rule incorporate implementation of 2012 Particulate ~latter NAAQS 

requirements with respect to the significant deterioration permitting program. The 

revision contains a grandfathering provision in the Specific Exemptions for PSD 

permitting requirements associated •d th the revised P7·\ rJAAQS that other\•Jise apply to 

permits issued on or after ~\arch 18, 2013. Permit applications that qualify for 

grandfathering are not required to show that emissions increases will not cause or 

contribute to a violation of the revised annual PM2.5 NAAQS, and rather may continue to 

be processed in accordance 1·Ji th the previously applicable p,'-1 NAAQS. 

The existing definition of Regulated NSR Pollutant (at subsection 2.66) generally 

excludes the measurement of condensable fraction of P7·\ in the context of the PSD 

regulations. However, the rule does preserve the requirement in some particular cases to 

include condensable Pfl as required by other regulations, such as new source performance 

standards. For purposes of PSD, the revised definition of

LEGISLATIVE RULE 

DEPARTMENT OF ENVIRONMENTAL PROTECTION 

AIR QUALITY 

SERIES 14 

PERMITS FOR CONSTRUCTION AND MAJOR MODIFICATION OF 

MAJOR STATIONARY SOURCES FOR THE 

PREVENTION OF SIGNIFICANT DETERIORATION OF AIR QUALITY 

§45-14-1. General. 

1.1. Scope. -- This rule establishes and adopts a preconstruction permit program in accordance with 

the policy of §101(b)(1) of the Clean Air Act (CAA), the purposes of §160 of the CAA, and the 

prevention of significant deterioration of air quality requirements of 40 CFR §51.166. Preconstruction 

permits issued pursuant to this rule shall contain emission limitations and such other measures as may be 

necessary for the prevention significant deterioration of air quality. This rule provides: 

l.l.a. A mechanism to ensure that economic growth will occur in harmony with the preservation of 

existing clean air resources; to prevent the development of any new non-attairnnent problems; to protect 

the public health and welfare from any adverse effects which might occur even at air quality levels better 

than the National Ambient Air Quality Standards; and to preserve, protect, and enhance the air quality in 

areas of special natural, recreational, scenic, or historic value. It is the intent of the Secretary to register 

and evaluate sources of air pollutants and to preclude the construction or relocation of any major 

stationary source or major modification in any area classified as attaining National Ambient Air Quality 

Standards or unclassifiable in which the establishment of such source or modification may interfere with 

the goals ofthe prevention of significant deterioration of air quality levels; and 

l.l.b. A method to quantitatively define significant deterioration of air quality with respect to the 

desired degree of preservation of air quality for various areas and to set forth procedures for registration 

and reporting, and the criteria for obtaining a permit to construct or relocate a major stationary source or 

make a major modification to a stationary source within a designated attainment or unclassified area of 

the State of West Virginia. Such construction, modification, or relocation without such a permit is a 

violation of this rule. 

1.2. Authority.-- W.Va. Code §22-5-4. 

1.3. Filing Date.-- May 1, 2013. 

1.4. Effective Date. -- .H!fte 1, 2013. 

1.5. Federal Regulation. -- Unless otherwise indicated, where reference to a federal regulation or 

standard appears in this rule, such regulation or standard will, for the purpose of this rule, be construed as 

that version which was in effect as of Juno 1, 2012 June 1, 2013. 

1.6. Former Rules. -- This legislative rule amends 45CSR14 - "Permits for Construction and Major 

Modification of Major Stationary Sources for the Prevention of Significant Deterioration of Air Quality" 

1 
45CSR14 

which was filed on May 1, 2012 May 1, 2013 and became effective on Juno 1, 2012 June 1, 2013. 

§45-14-2.Definitions. 

2.1. "Actual emissions" means the actual rate of emissions of a pollutant from an emissions unit, as 

described below, except that this definition shall not apply for calculating whether a significant emissions 

increase has occurred, or for establishing a PAL under section 25. Instead, subsections 2.63 and 2.8 shall 

apply for those purposes. 

2.l.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 consecutive 24-month period which 

precedes the particular date and which is representative of normal source operation. The Secretary may 

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 com busted during the selected time period. 

2.l.b. The Secretary may presume that source-specific allowable emissions for the unit are 

equivalent to the actual emissions of the unit. 

2.l.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.l.d. For an electric utility steam generating unit (other than a new unit or the replacement of an 

existing unit) actual emissions of the unit following the physical or operational change shall equal the 

representative actual annual emissions of the unit following the physical or operational change, provided 

the source owner or operator maintains and submits to the Director, on an annual basis for a period of five 

(5) years from the date the unit resumes regular operation, information demonstrating that the physical or 

operational change did not result in an emissions increase. A longer period, not to exceed ten (10) years, 

may be required by the Director if the Director determines such a period to be more representative of 

normal source operations following the physical or operational change. 

2.2. "Actuals PAL" for a major stationary source means a PAL based on the baseline actual 

emissions (as defined in subsection 2.8) of all emissions units (as defined in subsection 2.27) at the 

source, that emit or have the potential to emit the PAL pollutant. 

2.3. "Administrator" means the Administrator of the United States Envirornnental Protection 

Agency. 

2.4. "Adverse impact on visibility" means visibility impairment which interferes with the 

management, protection, preservation or enjoyment of the visitor's visual experience of the Federal Class 

I area. This determination must be made on a case-by-case basis taking into account the geographic 

extent, intensity, duration, frequency and time of visibility impairment, and how these factors correlate 

with (1) times of visitor use of the Federal Class I area, and (2) the frequency and timing of natural 

conditions that reduce visibility. 

2.5. "Air pollutants" means solids, liquids, or gases which, if discharged into the air, may result in 

statutory air pollution. 

2 
45CSR14 

2.6. "Air pollution" or "statutory air pollution" means and is limited to the discharge into the air by 

the act of man substances (liquid, solid, gaseous, organic or inorganic) in a locality, manner and amount 

as to be injurious to human health or welfare, animal or plant life, or property, or which would interfere 

with the enjoyment oflife or property. 

2.7. "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 or 

limits enforceable by the Secretary which restrict the operating rate, or hours of operation, or both) and 

the most stringent of the following: 

2.7.a. The applicable standards as set forth in 40 CFR Parts 60 and 61; 

2.7.b. The applicable State of West Virginia emissions limitations or permit conditions, including 

those with a future compliance date; or 

2.7.c. The applicable federally enforceable emissions limitations or permit conditions, including 

those with a future compliance date. 

2.8. "Baseline actual emissions" means the rate of emissions, in tons per year, of a regulated NSR 

pollutant, as determined in accordance with subdivisions 2.8.a through 2.8.d. 

2.8.a. For any existing electric utility steam generating unit, baseline actual emissions means the 

average emission rate, in tons per year, at which the unit actually emitted the pollutant during any 

consecutive 24-month period selected by the owner or operator within the 5-year period immediately 

preceding when the owner or operator begins actual construction of the project. The Secretary shall 

allow the use of a different time period upon a determination that it is more representative of normal 

source operation. 

2.8.a.l. The average rate shall include fugitive enusswns to the extent quantifiable, and 

emissions associated with startups, shutdowns, and malfunctions. 

2.8.a.2. The average rate shall be adjusted downward to exclude any noncompliant emissions 

that occurred while the source was operating above any emission limitation that was legally enforceable 

during the consecutive 24-month period. 

2.8.a.3. For a regulated NSR pollutant, when a project involves multiple emissions units, only 

one consecutive 24-month period must be used to determine the baseline actual emissions for the 

emissions units being changed. A different consecutive 24-month period can be used for each regulated 

NSR pollutant. 

2.8.a.4. 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 paragraph 2.8.a.2. 

2.8.b. For an existing emissions unit (other than an electric utility steam generating unit), baseline 

actual emissions means the average rate, in tons per year, at which the emissions unit actually emitted the 

pollutant during any consecutive 24-month period selected by the owner or operator within the 1 0-year 

period immediately preceding either the date the owner or operator begins actual construction of the 

project, or the date a complete permit application is received by the Secretary for a permit required under 

3 
45CSR14 

this rule, whichever is earlier, except that the 1 0-year period shall not include any period earlier than 

November 15, 1990. 

2.8.b.l. The average rate shall include fugitive enusswns to the extent quantifiable, and 

emissions associated with startups, shutdowns, and malfunctions. 

2.8.b.2. The average rate shall be adjusted downward to exclude any noncompliant emissions 

that occurred while the source was operating above an emission limitation that was legally enforceable 

during the consecutive 24-month period. 

2.8.b.3. The average rate shall be adjusted downward to exclude any enusswns 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. However, if an emission limitation is part of a maximum achievable control 

technology standard that the Administrator proposed or promulgated under 40 CFR Part 63, the baseline 

actual emissions need only be adjusted if the State has taken credit for such emissions reductions in an 

attainment demonstration or maintenance plan consistent with the requirements of 45CSR19-8.6. 

2.8.b.4. For a regulated NSR pollutant, when a project involves multiple emissions units, only 

one consecutive 24-month period must be used to determine the baseline actual emissions for all the 

emissions units being changed. A different consecutive 24-month period can be used for each regulated 

NSR pollutant. 

2.8.b.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 paragraphs 2.8.b.2 and 2.8.b.3. 

2.8.c. For a new emissions unit, the baseline actual em1sswns for purposes of determining the 

emissions increase that will result from the initial construction and operation of such unit shall equal zero; 

and thereafter, for all other purposes, shall equal the unit's potential to emit. 

2.8.d. For a PAL for a stationary source, the baseline actual emissions shall be calculated for 

existing electric utility steam generating units in accordance with the procedures contained in subdivision 

2.8.a, for other existing emissions units in accordance with the procedures contained in subdivision 2.8.b, 

and for a new emissions unit in accordance with the procedures contained in subdivision 2.8.c. 

2.9. Baseline Area. 

2.9.a. "Baseline area" means any intrastate area (and every part thereof) designated as attainment or 

unclassifiable under §107(d)(1)(A)(ii) or (iii) of the CAA in which the major source or major 

modification establishing the minor source baseline date would construct or would have an air quality 

impact for the pollutant for which the baseline date is established, equal to or greater than the following: 

Pollutant Air Quality Impact (annual 

average) 

so, 1 }.'g/m3 

4 
45CSR14 

N02 1J"g/m3 

PM10 1J"g/m3 

PMz.s 0.3 l"g/m3 

2.9.b. Area redesignations under §107(d)(l)(A)(ii) or (iii) of the CAA cannot intersect or be 

smaller than the area of impact of any major stationary source or major modification which: 

2.9.b.l. Establishes a minor source baseline date; or 

2.9.b.2. Is subject to 40 CFR §52.21 or this rule, and would be constructed in the same state as 

the state proposing the redesignation. 

2.9.c. Any baseline area established originally for the TSP increments shall remain in effect and 

shall apply for purposes of determining the amount of available PM10 increments, except that such 

baseline area shall not remain in effect if the Secretary rescinds the corresponding minor source baseline 

date in accordance with subdivision 2.42.d. 

2.10. "Baseline concentration" means that ambient concentration level which exists in the baseline 

area at the time of the applicable minor source baseline date. A baseline concentration is determined for 

each pollutant for which a minor source baseline date is established and includes: 

2.10.a. The allowable emissions of major stationary sources which commenced construction 

before the major source baseline date, but were not in operation by the applicable minor source baseline 

date. 

2.10.b. The actual emissions representative of sources in existence on the applicable minor 

source baseline date. However, the following will not be included in the baseline concentration and will 

affect the applicable maximum allowable increase(s): 

2.10.b.l. actual emissions from any major stationary source on which construction commenced 

after the major source baseline date; and 

2.10.b.2. actual emissions increases and decreases at any stationary source occurring after the

combustion techniques for control of such pollutant. In no event shall application of best available 

control technology result in emissions of any pollutant which would exceed the emissions allowed by any 

federally enforceable emissions limitations or emissions limitations enforceable by the Secretary. If the 

Secretary determines that technological or economic limitations on the application of measurement 

methodology to a particular emissions unit would make the imposition of an emissions standard 

infeasible, a design, equipment work practice, operational standard or combination thereof, may be 

prescribed instead to satisfY the requirement for the application of best available control technology.

3.1. The requirements of this rule apply to the construction of any new major stationary source (as 

defined in subsection 2.43) or any proposed project at an existing major stationary source in an area 

designated as attairnnent or unclassifiable under §§107(d)(1)(A)(ii) or (iii) ofthe CAA. 

3.2. The requirements of sections 7 through 13 and sections 17 through 19 apply to the construction 

of any new major stationary source or the major modification of any existing major stationary source, 

except as this rule otherwise provides. 

3.3. No new major stationary source or major modification to which the requirements of sections 7 

through 13 and sections 17 through subsection 19.7 apply shall begin actual construction without a permit 

issued by the Secretary that states that the major stationary source or major modification will meet those 

requirements. 

3.4. Determination of major modification. -- The determination as to whether a proposed project is a 

major modification for a regulated NSR pollutant shall be determined in accordance with the specific 

provisions set forth in subdivisions 3.4.a through 3.4.f. 

3.4.a. Except as otherwise provided in subsections 3.5 and 3.6, and consistent with the definition 

of major modification contained in subsection 2.40, a project is a major modification for a regulated NSR 

pollutant if it causes two types of emissions increases -- a significant emissions increase (as defined in 

subsection 2.75), and a significant net emissions increase (as defined in subsections 2.46 and 2.74). The 

proposed project is not a major modification if it does not cause a significant emissions increase. If the 

proposed project causes a significant emissions increase, then the project is a major modification only if it 

also results in a significant net emissions increase. 

3.4.b. The procedure for calculating (before beginning actual construction) whether a significant 

emissions increase (i.e., the first step of the process) will occur depends upon the type of emissions units 

being modified, according to subdivisions 3.4.c through 3.4.f. The procedure for calculating (before 

beginning actual construction) whether a significant net emissions increase will occur at the major 

stationary source (i.e., the second step of the process) is contained in the definition in subsection 2.46. 

Regardless of any such preconstruction projections, a major modification results if the project causes a 

significant emissions increase and a significant net emissions increase. 

3.4.c. Actual-to-projected-actual applicability test for projects that only involve existing emissions 

units. -- A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of 

the difference between the projected actual emissions (as defined in subsection 2.63) and the baseline 

actual emissions (as defined in subdivisions 2.8.a and 2.8.b), for each existing emissions unit, equals or 

exceeds the significant amount for that pollutant (as defined in subsection 2.74). 

3.4.d. Actual-to-potential test for projects that only involve construction of a new em1sswns 

unit(s). --A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of 

the difference between the potential to emit (as defined in subsection 2.58) from each new emissions unit 

23 
45CSR14 

following completion of the project and the baseline actual emissions (as defined in subdivision 2.8.c) of 

these units before the project equals or exceeds the significant amount for that pollutant (as defined in 

subsection 2.74). 

3.4.e. [Reserved] 

3.4.f. Hybrid test for projects that involve multiple types of emissions units. -- A significant 

emissions increase of a regulated NSR pollutant is projected to occur if the sum of the emissions increases 

for each emissions unit, using the method specified in subdivisions 3.4.c through 3.4.d as applicable with 

respect to each emissions unit, for each type of emissions unit equals or exceeds the significant amount 

for that pollutant (as defined in subsection 2.74). 

3.5. For any major stationary source subject to a PAL for a regulated NSR pollutant, the major 

stationary source shall comply with the requirements set forth in section 25.

exists, the analysis shall contain such air quality monitoring data as the Secretary determines is necessary 

to assess ambient air quality for that pollutant in any area that the emissions of that pollutant would affect. 

11.4. For those pollutants (other than non-methane hydrocarbons) for which such an ambient air 

quality standard does exist, the analysis shall contain continuous air quality monitoring data gathered for 

purposes of determining whether emissions of that pollutant would cause or contribute to a violation of 

the standard or any maximum allowable increase. 

11.5. All ambient air quality monitoring data that is required shall have been gathered over a period 

of one (1) year and shall represent the year preceding receipt of the application, except that, if the 

Secretary determines that a complete and adequate analysis can be accomplished with monitoring data 

gathered over a period shorter than one (1) year (but not to be less than four ( 4) months), the data that is 

required shall have been gathered over at least that shorter period.

stationary source or major modification solely by virtue of a relaxation in any limitation, enforceable by 

the Administrator or the Secretary, on the capacity of the source or modification otherwise to emit a 

pollutant (such as a restriction on hours of operation), shall become subject to the requirements of this 

rule as though construction had not yet commenced on the source or modification. 

19.8. Except as otherwise provided in subdivision 19.8.f, the following specific provisions apply with 

respect to any regulated NSR pollutant emitted from projects at existing emissions units at a major 

stationary source (other than projects at a source with a PAL) in circumstances where there is a reasonable 

possibility, within the meaning of subdivision 19.8.f, that a project that is not a part of a major 

modification may result in a significant emissions increase of such pollutant, and the owner or operator 

elects to use the method specified in paragraphs 2.63.a.1 through 2.63.a.3 for calculating projected actual 

enuSSlOllS. 

19.8.a. Before beginning actual construction of the project, the owner or operator shall document 

and maintain a record of the following information: 

19.8.a.l. A description ofthe proposed project; 

37 
45CSR14 

19.8.a.2. Identification of the emissions unit(s) whose emissions of a regulated NSR pollutant 

could be affected by the proposed project; and 

19.8.a.3. A description of the applicability test used to determine that the proposed project is 

not a major modification for any regulated NSR pollutant, including the baseline actual emissions, the 

projected actual emissions, the amount of emissions excluded under paragraph 2.63.a.2 and an 

explanation for why such amount was excluded, and any netting calculations, if applicable. 

19.8.b. If the emissions unit is an existing electric utility steam generating unit, before beginning 

actual construction, the owner or operator shall provide a copy of the information required under 

subdivision 19.8.a to the Secretary. Nothing in subdivision 19.8.b shall be construed to require the 

owner or operator of such a unit to obtain any determination from the Secretary before beginning actual 

construction. 

19.8.c. The owner or operator shall monitor the emissions of any regulated NSR pollutant that 

could increase as a result of the project and that is emitted by any emissions unit identified in paragraph 

19.8.a.l. The owner or operator shall calculate and maintain a record of the annual emissions, in tons per 

year on a calendar year basis, for a period of 5 years following resumption of regular operations after the 

change, or for a period of 10 years following resumption of regular operations after the change if the 

project increases the design capacity of or potential to emit that regulated NSR pollutant at such emissions 

unit. 

19.8.d. If the unit is an existing electric utility steam generating unit, the owner or operator shall 

submit a report to the Secretary within 60 days after the end of each year during which records must be 

generated under subdivision 19.8.c setting out the unit's annual emissions during the calendar year that 

preceded submission of the report. 

19.8.e. If the unit is an existing unit other than an electric utility steam generating unit, the owner 

or operator shall submit a report to the Secretary if the annual emissions, in tons per year, from the project 

identified in subdivision 19.8.a, exceed the baseline actual emissions (as documented and maintained 

pursuant to paragraph 19.8.a.3), by a significant amount (as defined in subsection 2.74) for that regulated 

NSR pollutant, and if such emissions differ from the preconstruction projection as documented and 

maintained pursuant to paragraph 19.8.a.3. Such report shall be submitted to the Secretary within 60 

days after the end of such year. The report shall contain the following: 

19.8.e.l. The name, address and telephone number of the major stationary source; 

19.8.e.2. The annual emissions as calculated pursuant to subdivision 19.8.c; and 

19.8.e.3. Any other information that the owner or operator wishes to include in the report (e.g., 

an explanation as to why the emissions differ from the preconstruction projection). 

19.8.f.A "reasonable possibility" under subsection 19.8 occurs when the owner or operator 

calculates the project to result in either: 

19.8.f.l. A projected actual emissions increase of at least 50 percent of the amount that is a 

"significant emissions increase," as defined under subsection 2.75 (without reference to the amount that is 

a significant net emissions increase), for the regulated NSR pollutant; or 

38 
45CSR14 

19.8.f.2. A projected actual emissions increase that, added to the amount of emissions excluded 

under paragraph 2.63.a.3, sums to at least 50 percent of the amount that is a "significant emissions 

increase," as defined under subsection 2.75 (without reference to the amount that is a significant net 

emissions increase), for the regulated NSR pollutant. For a project for which a reasonable possibility 

occurs only within the meaning of this paragraph, and not also within the meaning of paragraph 19.8.f.l, 

then provisions under subdivisions 19.8.b through 19.8.e do not apply to the project. 

19.9. The owner or operator of the source shall make available the information required to be 

documented and maintained pursuant to subsection 19.8 for review upon a request for inspection by the 

Secretary or the general public pursuant to the requirements contained in 45CSR30. 

§45-14-20. Disposition ofPermits. 

20.1. In the event that the Secretary promulgates changes to this rule or in the event of a redesignation 

of an attainment or non-attainment area (in accordance with§ 107 of the CAA) prior to final disposition 

of a permit, the Secretary shall make final disposition of the permit application in accordance with such 

newly promulgated standards or redesignation. 

§45-14-21. Conflict with Other Permitting Rules. 

21.1. For sources required to obtain a permit under this rule, the provisions of 45CSR13 requiring a 

permit do not apply, so that only a single permit is required; provided, however, that: 

2l.l.a. The base permit application fee of $1,000 pursuant to 45CSR22, subdivision 3.4.a shall 

apply to such sources in addition to other applicable fees; and 

2l.l.b. Any permit issued under this rule includes conditions that ensure compliance with the 

provisions of 45CSR13 to the extent applicable to any regulated air pollutant (as defined in 45CSR13) not 

otherwise covered under this rule. 

21.2. For sources that may be subject to 45CSR13, 45CSR14 and/or 45CSR19, the more stringent 

provisions of each applicable rule shall apply. 

§45-14-22. [Reserved.] 

§45-14-23. [Reserved.] 

§45-14-24. [Reserved]. 

§45-14-25. Actuals PALs. 

25.1. Applicability. 

25.l.a. The Secretary may approve the use of an actuals PAL for any existing major stationary 

source if the PAL meets the requirements in subsections 25.1 through 25.15. The term "PAL" shall mean 

"actuals PAL" throughout section 25. 

25.l.b. Any physical change in or change in the method of operation of a major stationary source 

39 
45CSR14 

that maintains its total source-wide emissions below the PAL level, meets the requirements in subsections 

25.1 through 25.15, and complies with the PAL permit: 

25.l.b.l. Is not a major modification for the PAL pollutant; 

25.l.b.2. Does not have to be approved through the PSD program; and 

25.l.b.3. Is not subject to the provisions in subsection 19.4 (restrictions on relaxing enforceable 

emission limitations that the major stationary source used to avoid applicability of the major NSR 

program). 

25.l.c. Except as provided under paragraph 25.l.b.3, a major stationary source shall continue to 

comply with all applicable Federal or State requirements, emission limitations, and work practice 

requirements that were established prior to the effective date of the PAL. 

25.2. Definitions. --For the purposes of this section 25, the definition in subdivision 25.2.a applies. 

When a term is not defined in these paragraphs, it shall have the meaning given in section 2 or in the 

CAA. 

25.2.a. Allowable emissions means "allowable emissions" as defined in subsection 2.6, except as 

modified according to paragraphs 25.2.a.1 and 25.2.a.2. 

25.2.a.l. The allowable emissions for any emissions unit shall be calculated considering any 

emission limitations that are enforceable as a practical matter on the emissions unit's potential to emit. 

25.2.a.2. An emissions unit's potential to emit shall be determined using the definition in 

subsection 2.58, except that the words "or enforceable as a practical matter" should be added after 

"federally enforceable." 

25.3. Permit application requirements.-- As part of a permit application requesting a PAL, the owner 

or operator of a major stationary source shall submit the following information to the Secretary for 

approval: 

25.3.a. A list of all emissions units at the source designated as small, significant or major based 

on their potential to emit. In addition, the owner or operator of the source shall indicate which, if any, 

Federal or State applicable requirements, emission limitations, or work practices apply to each unit. 

25.3.b. Calculations of the baseline actual emissions (with supporting documentation). Baseline 

actual emissions are to include emissions associated not only with operation of the unit, but also 

emissions associated with startup, shutdown, and malfunction. 

25.3.c. The calculation procedures that the major stationary source owner or operator proposes to 

use to convert the monitoring system data to monthly emissions and annual emissions based on a 

12-month rolling total for each month as required by subdivision 25.13.a. 

25.4. General requirements for establishing PALs. 

25.4.a. The Secretary is allowed to establish a PAL at a major stationary source, provided that at 

a minimum, the requirements in paragraphs 25.4.a.1 through 25.4.a.7 are met. 

40 
45CSR14 

25.4.a.l. The PAL shall impose an annual em1sswn limitation in tons per year, that is 

enforceable as a practical matter, for the entire major stationary source. For each month during the PAL 

effective period after the first 12 months of establishing a PAL, the major stationary source owner or 

operator shall show that the sum of the monthly emissions from each emissions unit under the PAL for 

the previous 12 consecutive months is less than the PAL (a 12-month average, rolled monthly). For each 

month during the first 11 months from the PAL effective date, the major stationary source owner or 

operator shall show that the sum of the preceding monthly emissions from the PAL effective date for each 

emissions unit under the PAL is less than the PAL. 

25.4.a.2. The PAL shall be established in a PAL permit that meets the public participation 

requirements in section 17. 

25.4.a.3. The PAL permit shall contain all the requirements of subsection 25. 7. 

25.4.a.4. The PAL shall include fugitive emissions, to the extent quantifiable, from all 

emissions units that emit or have the potential to emit the PAL pollutant at the major stationary source. 

25.4.a.5. Each PAL shall regulate emissions of only one pollutant. 

25.4.a.6. Each PAL shall have a PAL effective period of 10 years. 

25.4.a. 7. The owner or operator of the major stationary source with a PAL shall comply with 

the monitoring, recordkeeping, and reporting requirements provided in subsections 25.12 through 25.14 

for each emissions unit under the PAL through the PAL effective period. 

25.4.b. At no time during or after the PAL effective period are emissions reductions of a PAL 

pollutant that occur during the PAL effective period creditable as decreases for purposes of offsets 

pursuant to 45CSR19 unless the level of the PAL is reduced by the amount of such emissions reductions 

and such reductions would be creditable in the absence of the PAL. 

25.5. Public participation requirements for PALs.-- PALs for existing major stationary sources shall 

be established, renewed, or increased through a procedure that is consistent with 45CSR13. This 

includes the requirement that the Secretary provide the public with notice of the proposed approval of a 

PAL permit and at least a 30-day period for submittal of public comment. The Secretary must address all 

material comments before taking final action on the permit. 

25.6. Setting the 10-year actuals PAL level. 

25.6.a. Except as provided in subdivision 25.6.b, actuals PAL level for a major stationary source 

shall be established as the sum of the baseline actual emissions (as defined in subsection 2.8) of the PAL 

pollutant for each emissions unit at the source; plus an amount equal to the applicable significant level for 

the PAL pollutant under subsection 2.74 or under the CAA, whichever is lower. When establishing the 

actuals PAL level, for a PAL pollutant, only one consecutive 24-month period must be used to determine 

the baseline actual emissions for all existing emissions units. However, a different consecutive 24-month 

period may be used for each different PAL pollutant. Emissions associated with units that were 

permanently shutdown after this 24-month period must be subtracted from the PAL level. Emissions 

from units on which actual construction began after the 24-month period must be added to the PAL level 

in an amount equal to the potential to emit of the units. The Secretary shall specifY a reduced PAL 

41 
45CSR14 

level(s) (in tons/yr) in the PAL permit to become effective on the future compliance date(s) of any 

applicable Federal or State regulatory requirement(s) that the Secretary is aware of prior to issuance of the 

PAL permit. For instance, if the source owner or operator will be required to reduce emissions from 

industrial boilers in half from baseline emissions of 60 ppm NOx to a new rule limit of 30 ppm, then the 

permit shall contain a future effective PAL level that is equal to the current PAL level reduced by half of 

the original baseline emissions of such unit(s). 

25.6.b. For newly constructed units (which do not include modifications to existing units) on 

which actual construction began after the 24-month period, in lieu of adding the baseline actual emissions 

as specified in subdivision 25.6.a, the emissions must be added to the PAL level in an amount equal to the 

potential to emit of the units. 

25.7. Contents of the PAL permit.-- The PAL permit must contain, at a minimum, the information in 

subdivisions 25.7.a through 25.7.j. 

25. 7.a. The PAL pollutant and the applicable source-wide emission limitation in tons per year. 

25.7.b. The PAL permit effective date and the expiration date of the PAL (PAL effective period). 

25. 7.c. Specification in the PAL permit that if a major stationary source owner or operator 

applies to renew a PAL in accordance with subsection 25.10 before the end of the PAL effective period, 

then the PAL shall not expire at the end of the PAL effective period. It shall remain in effect until a 

revised PAL permit is issued by the Secretary. 

25. 7.d. A requirement that emission calculations for compliance purposes must include 

emissions from startups, shutdowns, and malfunctions. 

25. 7.e. A requirement that, once the PAL expires, the major stationary source is subject to the 

requirements of subsection 25.9. 

25. 7.f. The calculation procedures that the major stationary source owner or operator shall use to 

convert the monitoring system data to monthly emissions and annual emissions based on a 12-month 

rolling total as required by subdivision 25.13.a. 

25. 7.g. A requirement that the major stationary source owner or operator monitor all emissions 

units in accordance with the provisions under subsection 25.12. 

25. 7.h. A requirement to retain the records required under subsection 25.13 on site. Such 

records may be retained in an electronic format. 

25. 7.i. A requirement to submit the reports required under subsection 25.14 by the required 

deadlines. 

25. 7.j. Any other requirements that the Secretary deems necessary to implement and enforce the 

PAL. 

25.8. PAL effective period and reopening of the PAL permit. -- The requirements in subdivisions 

25.8.a and 25.8.b apply to actuals PALs. 

42 
45CSR14 

25.8.a. PAL effective period.-- The Secretary shall specify a PAL effective period of 10 years. 

25.8.b. Reopening of the PAL permit. 

25.8.b.l. During the PAL effective period, the Secretary must reopen the PAL permit to: 

25.8.b.l.A. Correct typographical or calculation errors made in setting the PAL or reflect a 

more accurate determination of emissions used to establish the PAL; 

25.8.b.l.B. Reduce the PAL if the owner or operator of the major stationary source creates 

creditable emissions reductions for use as offsets pursuant to 45CSR19; and 

25.8.b.l.C. Revise the PAL to reflect an increase in the PAL as provided under subsection 

25 .11. 

25.8.b.2. The Secretary shall have discretion to reopen the PAL permit for the following: 

25.8.b.2.A. Reduce the PAL to reflect newly applicable Federal requirements (for example, 

NSPS) with compliance dates after the PAL effective date; 

25.8.b.2.B. Reduce the PAL consistent with any other requirement, that is enforceable as a 

practical matter, and that the State may impose on the major stationary source under the State 

Implementation Plan; and 

25.8.b.2.C. Reduce the PAL if the Secretary determines that a reduction is necessary to 

avoid causing or contributing to a National Ambient Air Quality Standard (NAAQS) or PSD increment 

violation, or to an adverse impact on an air quality related value that has been identified for a Federal 

Class I area by a Federal Land Manager and for which information is available to the general public. 

25.8.b.3. Except for the permit reopening in subparagraph 25.8.b.l.A for the correction of 

typographical/calculation errors that do not increase the PAL level, all other reopenings shall be carried 

out in accordance with the public participation requirements of subsection 25.5. 

25.9. Expiration of a PAL. -- Any PAL that is not renewed in accordance with the procedures in 

subsection 25.10 shall expire at the end of the PAL effective period, and the requirements in subdivisions 

25.9.a through 25.9.e shall apply. 

25.9.a. Each emissions unit (or each group of emissions units) that existed under the PAL shall 

comply with an allowable emission limitation under a revised permit established according to the 

procedures in paragraphs 25.9.a.l and 25.9.a.2. 

25.9.a.l. Within the time frame specified for PAL renewals in subdivision 25.10.b, the major 

stationary source shall submit a proposed allowable emission limitation for each emissions unit (or each 

group of emissions units, if such a distribution is more appropriate as decided by the Secretary) by 

distributing the PAL allowable emissions for the major stationary source among each of the emissions 

units that existed under the PAL. If the PAL had not yet been adjusted for an applicable requirement that 

became effective during the PAL effective period, as required under subdivision 25.10.e, such distribution 

shall be made as if the PAL had been adjusted. 

43 
45CSR14 

25.9.a.2. The Secretary shall decide whether and how the PAL allowable emissions will be 

distributed and issue a revised permit incorporating allowable limits for each emissions unit, or each 

group of emissions units, as the Secretary determines is appropriate. 

25.9.b. Each emissions unit(s) shall comply with the allowable em1sswn limitation on a 

12-month rolling basis. The Secretary may approve the use of monitoring systems (source testing, 

emission factors, etc.) other than CEMS, CERMS, PEMS, or CPMS to demonstrate compliance with the 

allowable emission limitation. 

25.9.c. Until the Secretary issues the revised permit incorporating allowable limits for each 

emissions unit, or each group of emissions units, as required under paragraph 25.9.a.2, the source shall 

continue to comply with a source-wide, multi-unit emissions cap equivalent to the level of the PAL 

emission limitation. 

25.9.d. Any physical change or change in the method of operation at the major stationary source 

will be subject to major NSR requirements if such change meets the definition of major modification in 

subsection 2.40. 

25.9.e. The major stationary source owner or operator shall continue to comply with any State or 

Federal applicable requirements (BACT, RACT, NSPS, etc.) that may have applied either during the PAL 

effective period or prior to the PAL effective period except for those emission limitations that had been 

established pursuant to subsection 19.4, but were eliminated by the PAL in accordance with the 

provisions in paragraph 25.l.b.3. 

25.10.Renewal of a PAL.-- The Secretary shall follow the procedures specified in subsection 25.5 in 

approving any request to renew a PAL for a major stationary source, and shall provide both the proposed 

PAL level and a written rationale for the proposed PAL level to the public for review and comment. 

During such public review, any person may propose a PAL level for the source for consideration by the 

Secretary. 

25.10.a. Application deadline. -- A major stationary source owner or operator shall submit a 

timely application to the Secretary to request renewal of a PAL. A timely application is one that is 

submitted at least 6 months prior to, but not earlier than 18 months from, the date of permit expiration. 

This deadline for application submittal is to ensure that the permit will not expire before the permit is 

renewed. If the owner or operator of a major stationary source submits a complete application to renew 

the PAL within this time period, then the PAL shall continue to be effective until the revised permit with 

the renewed PAL is issued. 

25.10.b. Application requirements. -- The application to renew a PAL permit shall contain the 

information required in paragraphs 25.10.c.1 through 25.10.c.4. 

25.10.b.l. The information required in subdivisions 25.3.a through 25.3.c. 

25.10.b.2. A proposed PAL level. 

25.10.b.3. The sum of the potential to emit of all em1sswns units under the PAL (with 

supporting documentation). 

44 
45CSR14 

25.10.b.4. Any other information the owner or operator wishes the Secretary to consider in 

determining the appropriate level for renewing the PAL. 

25.10.c. PAL adjustment. -- In determining whether and how to adjust the PAL, the Secretary 

shall consider the options outlined in paragraphs 25.10.d.l and 25.10.d.2. However, in no case may any 

such adjustment fail to comply with paragraph 25.10.d.3. 

25.10.c.l. If the emissions level calculated in accordance with subsection 25.6 is equal to or 

greater than 80 percent of the PAL level, the Secretary may renew the PAL at the same level without 

considering the factors set forth in paragraph 25.10.d.2; or 

25.10.c.2. The Secretary may set the PAL at a level that he or she determines to be more 

representative of the source's baseline actual emissions, or that he or she determines to be more 

appropriate considering air quality needs, advances in control technology, anticipated economic growth in 

the area, desire to reward or encourage the source's voluntary emissions reductions, or other factors as 

specifically identified by the Secretary in his or her written rationale. 

25.10.c.3. Notwithstanding paragraphs 25.10.d.l and 25.10.d.2: 

25.10.c.3.A. If the potential to emit of the major stationary source is less than the PAL, the 

Secretary shall adjust the PAL to a level no greater than the potential to emit of the source; and 

25.10.c.3.B. The Secretary shall not approve a renewed PAL level higher than the current 

PAL, unless the major stationary source has complied with the provisions of subsection 25.11 (increasing 

a PAL). 

25.10.d. If the compliance date for a State or Federal requirement that applies to the PAL source 

occurs during the PAL effective period, and if the Secretary has not already adjusted for such 

requirement, the PAL shall be adjusted at the time of PAL permit renewal or title V permit renewal, 

whichever occurs first. 

25 .11. Increasing a PAL during the PAL effective period. 

25.ll.a. The Secretary may increase a PAL emission limitation only if the major stationary source 

complies with the provisions in paragraphs 25.ll.a.l and 25.ll.a.2. 

25.ll.a.l. The owner or operator of the major stationary source shall submit a complete 

application to request an increase in the PAL limit for a PAL major modification. Such application shall 

identifY the emissions unit(s) contributing to the increase in emissions so as to cause the major stationary 

source's emissions to equal or exceed its PAL. 

25.ll.a.2. As part of this application, the major stationary source owner or operator shall 

demonstrate that the sum of the baseline actual emissions of the small emissions units, plus the sum of the 

baseline actual emissions of the significant and major emissions units assuming application of BACT 

equivalent controls, plus the sum of the allowable emissions of the new or modified emissions unit(s) 

exceeds the PAL. The level of control that would result from BACT equivalent controls on each 

significant or major emissions unit shall be determined by conducting a new BACT analysis at the time 

45 
45CSR14 

the application is submitted, unless the emissions unit is currently required to comply with a BACT or 

LAER requirement that was established within the preceding 10 years. In such a case, the assumed 

control level for that emissions unit shall be equal to the level of BACT or LAER with which that 

emissions unit must currently comply. 

25.1l.a.3. The owner or operator obtains a major NSR permit for all enusswns unit(s) 

identified in paragraph 25.1l.a.1, regardless of the magnitude of the emissions increase resulting from 

them (that is, no significant levels apply). These emissions unit(s) shall comply with any emissions 

requirements resulting from the major NSR process (for example, BACT), even though they have also 

become subject to the PAL or continue to be subject to the PAL. 

25.1l.a.4. The PAL permit shall require that the increased PAL level shall be effective on the 

day any emissions unit that is part of the PAL major modification becomes operational and begins to emit 

the PAL pollutant. 

25.1l.b. The Secretary shall calculate the new PAL as the sum of the allowable emissions for each 

modified or new emissions unit, plus the sum of the baseline actual emissions of the significant and major 

emissions units (assuming application of BACT equivalent controls as determined in accordance with 

paragraph 25.1l.a.2), plus the sum ofthe baseline actual emissions of the small emissions units. 

25.1l.c. The PAL permit shall be revised to reflect the increased PAL level pursuant to the public 

notice requirements of subsection 25.5. 

25 .12. Monitoring requirements for PALs. 

25.12.a. General requirements. 

25.12.a.l. Each PAL permit must contain enforceable requirements for the monitoring 

system that accurately determines plantwide emissions of the PAL pollutant in terms of mass per unit of 

time. Any monitoring system authorized for use in the PAL permit must be based on sound science and 

meet generally acceptable scientific procedures for data quality and manipulation. Additionally, the 

information generated by such system must meet minimum legal requirements for admissibility in a 

judicial proceeding to enforce the PAL permit. 

25.12.a.2. The PAL monitoring system must employ one or more of the four general 

monitoring approaches meeting the minimum requirements set forth in paragraphs 25.12.b.1 through 

25.12.b.4 and must be approved by the Secretary. 

25.12.a.3. Notwithstanding paragraph 25.12.a.2, you may also employ an alternative 

monitoring approach that meets paragraph 25.12.a.1 if approved by the Secretary. 

25.12.a.4. Failure to use a monitoring system that meets the requirements of this rule renders 

the PAL invalid. 

25.12.b. Minimum performance requirements for approved monitoring approaches. The 

following are acceptable general monitoring approaches when conducted in accordance with the 

minimum requirements in subdivisions 25.12.c through 25.12.i: 

46 
45CSR14 

25.12.b.l. Mass balance calculations for activities using coatings or solvents; 

25.12.b.2. CEMS; 

25.12.b.3. CPMS or PEMS; and 

25.12.b.4. Emission factors. 

25.12.c. Mass balance calculations. -- An owner or operator using mass balance calculations to 

monitor PAL pollutant emissions from activities using coating or solvents shall meet the following 

requirements: 

25.12.c.l. Provide a demonstrated means of validating the published content of the PAL 

pollutant that is contained in or created by all materials used in or at the emissions unit; 

25.12.c.2. Assume that the emissions unit emits all of the PAL pollutant that is contained in 

or created by any raw material or fuel used in or at the emissions unit, if it cannot otherwise be accounted 

for in the process; and 

25.12.c.3. Where the vendor of a material or fuel, which is used in or at the emissions unit, 

publishes a range of pollutant content from such material, the owner or operator must use the highest 

value of the range to calculate the PAL pollutant emissions unless the Secretary determines there is 

site-specific data or a site-specific monitoring program to support another content within the range. 

25.12.d. CEMS. An owner or operator using CEMS to monitor PAL pollutant emissions shall 

meet the following requirements: 

25.12.d.l. CEMS must comply with applicable Performance Specifications found in 40 CFR 

Part 60, appendix B; and 

25.12.d.2. CEMS must sample, analyze and record data at least every 15 minutes while the 

emissions unit is operating. 

25.12.e. CPMS or PEMS. An owner or operator using CPMS or PEMS to monitor PAL 

pollutant emissions shall meet the following requirements: 

25.12.e.l. The CPMS or the PEMS must be based on current site-specific data demonstrating 

a correlation between the monitored parameter(s) and the PAL pollutant emissions across the range of 

operation of the emissions unit; and 

25.12.e.2. Each CPMS or PEMS must sample, analyze, and record data at least every 15 

minutes, or at another less frequent interval approved by the Secretary, while the emissions unit is 

operating. 

25.12.f. Emission factors. -- An owner or operator using em1sswn factors to monitor PAL 

pollutant emissions shall meet the following requirements: 

25.12.f.l. All emission factors shall be adjusted, if appropriate, to account for the degree of 

47 
45CSR14 

uncertainty or limitations in the factors' development; 

25.12.f.2. The emissions unit shall operate within the designated range of use for the emission 

factor, if applicable; and 

25.12.f.3. If technically practicable, the owner or operator of a significant emissions unit that 

relies on an emission factor to calculate PAL pollutant emissions shall conduct validation testing to 

determine a site-specific emission factor within 6 months of PAL permit issuance, unless the Secretary 

determines that testing is not required. 

25.12.g. A source owner or operator must record and report maximum potential emissions without 

considering enforceable emission limitations or operational restrictions for an emissions unit during any 

period of time that there is no monitoring data, unless another method for determining emissions during 

such periods is specified in the PAL permit. 

25.12.h. Notwithstanding the requirements in subdivisions 25.12.c through 25.12.g, where an 

owner or operator of an emissions unit cannot demonstrate a correlation between the monitored 

parameter(s) and the PAL pollutant emissions rate at all operating points of the emissions unit, the 

Secretary shall, at the time of permit issuance: 

25.12.h.l. Establish default value(s) for determining compliance with the PAL based on the 

highest potential emissions reasonably estimated at such operating point(s); or 

25.12.h.2. Determine that operation of the emissions unit during operating conditions when 

there is no correlation between monitored parameter(s) and the PAL pollutant emissions is a violation of 

the PAL. 

25.12.i. Re-validation. -- All data used to establish the PAL pollutant must be re-validated 

through performance testing or other scientifically valid means approved by the Secretary. Such testing 

must occur at least once every 5 years after issuance ofthe PAL. 

25 .13. Recordkeeping requirements.
