(iii) A physical change or change in the method of operation shall not 

include standing alone: 

(A)(a) Routine maintenance, repair and replacement; 

'-—• (B) (b) Use of an alternative fuel or raw material by reason of an order 

under sections 2 (a) and (b) of the Energy Supply and Environmental 

Coordination Act of 1974 (or any superseding legislation) or by reason of a 

natural gas curtailment plant pursuant to the Federal Power Act? 

(C) (c) Use of an alternative fuel by reason of an order or rule under 

section 125 of the Act; 

(D) (d) Use of an alternative fuel at a steam generating unit to the 

extent that the fuel is generated from municipal solid waste; 

(E) (e) Use of an alternative fuel or raw material by a stationary source 

which: 

(1) The source was capable of accommodating before January 6, 1975, 

unless such change would be prohibited under any federally enforceable 

permit condition which was established after January 6, 1975 pursuant to 40 

CFR 52.21 or under regulations approved pursuant to 40 CFR subpart I or 40 

CFR 51.166; or 

(2) The source is approved to use under any permit issued under 40 CFR 

52.21 or under regulations approved pursuant to 40 CFR 51.166; 

(F) (f) An increase in the hours of operation or in the production rate, 

nless such change would be prohibited under any federally enforceable 

irmit condition which was established after January 6, 1975, pursuant to 

v—«f0 CFR S2.21 or under regulations approved pursuant to 40 CFR subpart I or 

40 CFR 51.166. 

(G)(g) Any change in ownership at a stationary source. 

(H)(h) The addition, replacement or use of a pollution control project 

at an existing emissions electric utility steam generating unit, unless the 

pollution control project will result in a significant net increase in 

representative actual annual emissions of any pollutant regulated under the 

Act and the Administrator determines that this increase will cause or 

contribute to a violation of any national ambient air quality standard or 

prevention of significant deterioration increment or wMOsaHEt&e an adverse 

impact on any air quality related value (including visibility) at any Class 

I area. For the purpose of this paragraph, in lieu of the source's 

representative actual annual emissions, the emissions levels used for that 

source in the most recent air guality impact analysis in the area conducted 

for the purpose of title I, if any, may be used. Administrator determines 

that such addition, replacement, or use renders the unit less 

environmentally beneficial, or except: 

(1) When the Administrator has reason to believe that the pollution 

control project would result in a significant net increase in 

representative actual annual emissions of any criteria pollutant over 

levels used for that source in the most recent air quality impact analysis

particulate matter, or nitrogen oxide, which occurs before the applicable 

minor source baseline date is creditable only if it is required to be 

considered in calculating the amount of maximum allowable increases 

remaining available. With respect to particulate matter, only PM-10 

nissions can be used to evaluate the net emissions increase for PM-10. 

*-

L§52.21(b) (3) (iv) revised at 58 FR 31636, June 3, 1993] 

(v) An increase in actual emissions is creditable only to the extent 

that the new level of actual emissions exceeds the old level. 

(vi) A decrease in actual emissions is creditable only to the extent 

that: 

(A)(a) The old level of actual emissions or the old level of allowable 

emissions, whichever is lower, exceeds the new level of actual emissions; 

(B)(b) It is federally enforceable at and after the time that actual 

construction on the particular change begins; and 

(C)(c) It has approximately the same qualitative significance for public 

health and welfare as that attributed to the increase from the particular 

change such that, at a minimum, the decrease is sufficient to prevent the 

proposed increased from causing or contributing to a violation of any 

national ambient air quality standard or any applicable air quality 

increment under paragraph (c) of this section or ha»ii»g an adverse impact 

on air quality related values (including visibility) in Class I areas. 

(vii) [Reserved] 

(viii) An increase that results from a physical change at a source 

ccurB when the emissions unit on which construction occurred becomes 

—Operational and begins to emit a particular pollutant. Any replacement unit 

that requires shakedown becomes operational only after a reasonable 

shakedown period, not to exceed 180 days. 

(4) Potential to emit means the maximum capacity of a stationary source 

to emit a pollutant under its physical and operational design. Any physical 

or operational limitation on the capacity of the source to emit a 

pollutant, including air pollution control equipment and restrictions on 

hours of operation or on the type or amount of material combusted, stored, 

or processed, shall be treated as part of its design if the limitation or 

the effect it would have on emissions is federally enforceable, secondary 

emissions do not count in determining the potential to emit of a stationary 

source. 

(5) Stationary source means any building, structure, facility, or 

installation which emits or may emit any air pollutant subject to 

regulation under the Act. 

(6) Building, structure, facility, or installation means all of the 

pollutant-emitting activities which belong to the same industrial grouping, 

are located on one or more contiguous or adjacent properties, and are under 

the control of the same person (or persons under common control) except the 

activities of any vessel. Pollutant-emitting activities shall be considered 

as part of the same industrial grouping if they belong to the same "Major 

Group" (i.e., which have the same first two digit code) as described in the 

Standard Industrial Classification Manual, 1972, as amended by the 1977 

—^Supplement (U. S. Government Printing Office stock numbers 4101-0066 and 

003-005-00176*0, respectively).

a proposed major source or major modification may cause or contribute 

change in the air quality in such area and identifying the potential s-r 

Jovd[ 

responsibility for management of such lands have an affirmative 

responsibility to protect the air quality related values (including 

visibility) of such lands and to consider, in consultation with the 

Administrator, whether a proposed source or modification will have an 

'verse impact on such values. 

N ^ > (2) General requirements. (i) Notification of potential impacts on a 

Federal class I area and requirement for impact assessment. Where the 

Federal Official, Federal Land Manager, the Administrator, the Governor of 

an adjacent State, or the governing body of an adjacent Indian Tribe 

containing a Federal Class I-area, files a notice alleging that emissions 

from 

to a 

adverse impact of such change, a permit shall not be issued unless the 

owner or operator of such source: (A) demonstrates to the satisfaction of 

the Administrator that emissions will not cause or contribute to ambient 

air quality concentrations in the Federal Class I area which violate the 

maximum allowable increases oyer baseline concentrations, and (B) provides 

an analysis of the potential impacts on air quality related values at the 

Federal Class I area. A permit otherwise prohibited under this clause may 

be issued in accordance with the variance provisions in paragraph (p)(8) 

through (p)(11) of this section. 

(ii) Available information on air quality related values and analytical 

methods. The Federal Land Manager or Federal Official shall provide to the 

owner or operator of a proposed major source or major modification that may 

have an adverse impact on air quality related values in a Federal class I 

area all available information about such values and methods to analyze 

potential impacts. 

(iii) Consultation with Federal Land Manager. The Administrator shall 

.vide for consultation and coordination with the Federal Land Manager 

v^icluding the procedures contained in paragraph (p)(3) through (p)(6) of 

this section. 

(3) Pre-application coordination. For a proposed major source or major 

modification within 100 kilometers of a Federal Class I area— 

(i) The affected Federal Land Manager shall be notified within 30 days 

from receipt by the Administrator of advance notification of a permit 

application, and 

(ii) The affected Federal Land Manager shall be given reasonable notice 

and an opportunity to participate in pre-application meetings with the 

applicant. 

(4) Permit application coordination, (i) The Federal Land Manager of 

any Federal Class I area within 100 kilometers of a proposed major source 

or major modification shall be provided with a copy of the permit 

application and other relevant information; 

(il) The Federal Land Manager shall Toe provided with a copy of a permit 

application requested within 7{days from the date information is registered 

on the applicable EPA electronic bulletin board (in accordance with 

paragraph (n)(4) of this section); 

(5) Completeness determination coordination. Prior to making the 

ipleteness determination under paragraph (n)(l) of this section, the 

w-ministrator shall— 

(i) Ensure that the applicant has provided any analysis required 

pursuant to paragraph (p)(2)(i) of this section; 
P.7

values. The owner or operator of a proposed major source or major 

modification may mitigate an adverse impact by obtaining enforceable and 

permanent emissions reductions of sufficient amount and in such location 

thatr^He reductions will offset the change in air quality in the Federal 

"lass I area that would have resulted from the proposed source. 

, (3) Visibility analysis. The Administrator shall consider any analysis 

performed by the Federal land manager, provided within 30 days of the 

notification required by paragraph (p)(1) of this section, that shows that 

a proposed new major stationary source or major modification may have an 

adverse impact on visibility in any Federal class I area, where the 

Administrator finds that such an analysis does not demonstrate to the 

satisfaction of the Administrator that an adverse impact on visibility will 

result in the Federal Class I area, the Administrator must, in the notice 

of public hearing on the permit application, either explain his decision(o 

give notice as to where the explanation can be obtained. 

(4) Denial-impact on air quality related values. The Federal Land 

Manager of any such lands may demonstrate to the Administrator that the 

emissions from a proposed source or modification would have an adverse 

impact on the air quality-related values (including visibility) of those 

lands, notwithstanding that the change in air quality resulting from 

emissions from such source or modification would not cause or contribute to 

concentrations which would exceed the maximum allowable increases for a 

Class I area. If the Administrator concurs with such demonstration, then he 

shall not issue the permit. 

(8)(5) Class I variances. The owner or operator of a proposed source or 

modification may demonstrate to the Federal Land Manager that the emissions 

from such source or modification would have no adverse impact on the air 

—•ality related values of any such lands (including visibility), 

withstanding that the change in air quality resulting from emissions 

.worn such source or modification would cause or contribute to 

concentrations which would exceed the maximum allowable increases for a 

Class I area. If the Federal Land Manager concurs with such demonstration 

and he so certifies, the State may authorize the Administrator: Provided,/ 

That the applicable requirements of this section are otherwise met, to 

issue the permit with such emission limitations as may be necessary to 

assure that emissions of sulfur dioxide and particulate matter would nc 

exceed the followng maximum allowable increases over baseline concentration
