ADDENDUM A
STATUTES
42 U.S.C. § 7411. Standards of performance for new station-
ary sources
(a) Definitions
For purposes of this section:
x * * *&

(2) The term “new source” means any stationary source, the
construction or modification of which is commenced after the
publication of regulations (or, if earlier, proposed regulations)
prescribing a standard of performance under this section
which will be applicable to such source.

7s

(4) The term “modification” means any physical change in, or
change in the method of operation of, a stationary source
which increases the amount of any air pollutant emitted by
such source or which results in the emission of any air pollut-
ant not previously emitted.

xs *£ * *

42 U.S.C. § 7470. Congressional declaration of purpose
The purposes of this part are as follows:

(1) to protect public health and welfare from any actual or
potential adverse effect which in the Administrator’s judg-
ment may reasonably be anticipate’ to occur from air pollu-
tion or from exposures to pollutants in other media, which .
pollutants originate as emissions to the ambient air),’ notwith-

' So in original. Probably should be “anticipated”.

standing attainment and maintenance of all national ambient
air quality standards;

(2) to preserve, protect, and enhance the air quality in national
parks, national wilderness areas, national monuments, na-
tional seashores, and other areas of special national or re-
gional natural, recreational, scenic, or historic value;

(3) to insure that economic growth will occur in a manner
consistent with the preservation of existing clean air re-
sources;

(4) to assure that emissions from any source in any State will
not interfere with any portion of the applicable implementa-
tion plan to prevent significant deterioration of air quality for
any other State; and

(5) to assure that any decision to permit increased air pollu-
tion in any area to which this section applies is made only af-
ter careful evaluation of all the consequences of such a deci-
sion and after adequate procedural opportunities for informed
public participation in the decisionmaking process.

42 U.S.C. § 7475. Preconstruction requirements

(a) Major emitting facilities on which construction is com-
menced

No major emitting facility on which construction is com-
menced after August 7, 1977, may be constructed in any area
to which this part applies unless—

(1) a permit has been issued for such proposed facility in
accordance with this part setting forth emission limita-
tions for such facility which conform to the requirements
of this part;

(2) the proposed permit has been subject to a review in
accordance with this section, the required analysis has
been conducted in accordance with regulations promul-
gated by the Administrator, and a public hearing has

3a

been held with opportunity for interested persons includ-
ing representatives of the Administrator to appear and
submit written or oral presentations on the air quality
impact of such source, alternatives thereto, control tech-
nology requirements, and other appropriate considera-
tions;

(3) the owner or operator of such facility demonstrates,
as required pursuant to section 7410(j) of this title, that
emissions from construction or operation of such facility
will not cause, or contribute to, air pollution in excess of
any (A) maximum allowable increase or maximum al-
lowable concentration for any pollutant in any area to
which this part applies more than one time per year, (B)
national ambient air quality standard in any air quality
control region, or (C) any other applicable emission
standard or standard of performance under this chapter;

(4) the proposed facility is subject to the best available
control technology for each pollutant subject to regula-
tion under this chapter emitted from, or which results
from, such facility;

(5) the provisions of subsection (d) of this section with
respect to protection of class I areas have been complied
with for such facility;

(6) there has been an analysis of any air quality impacts
projected for the area as a result of growth associated
with such facility;

(7) the person who owns or operates, or proposes to own
or operate, a major emitting facility for which a permit is
required under this part agrees to conduct such monitor-
ing as may be necessary to determine the effect which
emissions from any such facility may have, or is having,
on air quality in any arca which may be affected by
emissions from such source; and

(8) in the case of a source which proposes to construct in

4a

a class III area, emissions from which would cause or
contribute to exceeding the maximum allowable incre-
ments applicable in a class II area and where no standard
under section 7411 of this title has been promulgated
subsequent to August 7, 1977, for such source category,
the Administrator has approved the determination of best
available technology as set forth in the permit.

42 U.S.C. § 7479. Definitions
For purposes of this part—

(1) The term “major emitting facility” means any of the fol-
lowing stationary sources of air pollutants which emit, or
have the potential to emit, one hundred tons per year or more
of any air pollutant from the following types of stationary
sources: fossil-fuel fired steam electric plants of more than
two hundred and fifty million British thermal units per hour
heat input, coal cleaning plants (thermal dryers), kraft pulp
mills, Portland Cement plants, primary zinc smelters, iron and
steel mill plants, primary aluminum ore reduction plants, pri-
mary copper smelters, municipal incinerators capable of
charging more than fifty tons of refuse per day, hydrofluoric,
sulfuric, and nitric acid plants, petroleum refineries, lime
plants, phosphate rock processing plants, coke oven batteries,
sulfur recovery plants, carbon black plants (furnace process),
primary lead smelters, fuel conversion plants, sintering plants,
secondary metal production facilities, chemical process
plants, fossil-fuel boilers of more than two hundred and fifty
million British thermal units per hour heat input, petroleum
storage and transfer facilities with a capacity exceeding three
hundred thousand barrels, taconite ore processing facilitics,
glass fiber processing plants, charcoal production facilities.
Such term also includes any other source with the potential to
emit two hundred and fifty tons per year or more of any air
pollutant. This term shall not include new or modified facili-

Sa

ties which are nonprofit health or education institutions which
have been exempted by the State.

(2)(A) The term “commenced” as applied to construction of a
major emitting facility means that the owner or operator has
obtained all necessary preconstruction approvals or permits
required by Federal, State, or local air pollution emissions and
air quality laws or regulations and either has (i) begun, or
caused to begin, a continuous program of physical on-site
construction of the facility or (ii) entered into binding agree-
ments or contractual obligations, which cannot be canceled or
modified without substantial loss to the owner or operator, to
undertake a program of construction of the facility to be com-
pleted within a reasonable time.

(B) The term “necessary preconstruction approvals or
permits” means those permits or approvals, required by
the permitting authority as a precondition to undertaking
any activity under clauses (i) or (ii) of subparagraph (A)
of this paragraph.

(C) The term “construction” when used in connection
with any source or facility, includes the modification (as
defined in section 741 1(a) of this title) of any source or
facility.

(3) The term “best available control technology” means an
emission limitation based on the maximum degree of reduc-
tion of each pollutant subject to regulation under this chapter
emitted from or which results from any major emitting facil-
ity, which the permitting authority, on a case-by-case basis,
taking into account energy, environmental, and economic im-
pacts and other costs, determines is achievable for such facil-
ity through application of production processes and available
methods, systems, and techniques, including fuel cleaning,
clean fuels, or treatment or innovative fuel combustion tech-
niques for control of each such pollutant. In no event shall
application of “best available control technology” result in
emissions of any pollutants which will exceed the emissions

6a

allowed by any applicable standard established pursuant to
section 7411 or 7412 of this title. Emissions from any source
utilizing clean fuels, or any other means, to comply with this
paragraph shall not be allowed to increase above levels that
would have been required under this paragraph as it existed
prior to November 15, 1990.

7a

other nationally applicable regulations promulgated, or
final action taken, by the Administrator under this chap-
ter may be filed only in the United States Court of Ap-
peals for the District of Columbia. A petition for review
of the Administrator’s action in approving or promulgat-
ing any implementation plan under section 7410 of this
title or section 7411(d) of this title, any order under
section 7411()) of this title, under section 7412 of this ti-
tle,” under section 7419 of this title, or under section
7420 of this title, or his action under section 1857c-
10(c)(2)(A), (B), or (C) of this title (as in effect before
August 7, 1977) or under regulations thereunder, or re-
vising regulations for enhanced monitoring and compli-
ance certification programs under section 7414(a)(3) of
this title, or any other final action of the Administrator
under this chapter (including any denial or disapproval
by the Administrator under subchapter I of this chapter)
which is locally or regionally applicable may be filed
only in the United States Court of Appeals for the ap-
propriate circuit. Notwithstanding the preceding sen-
tence a petition for review of any action referred to in
such sentence may be filed only in the United States
Court of Appeals for the District of Columbia if such ac-
tion is based on a determination of nationwide scope or
effect and if in taking such action the Administrator
finds and publishes that such action is based on such a
determination. Any petition for review under this sub-
section shall be filed within sixty days from the date no-
tice of such promulgation, approval, or action appears in
the Federal Register, except that if such petition is based
solely on grounds arising after such sixtieth day, then
any petition for review under this subsection shall be
filed within sixty days after such grounds arise. The fil-
ing of a petition for reconsideration by the Administrator
of any otherwise final rule or action shall not affect the

“So in original.

finality of such rule or action for purposes of judicial re-
view nor extend the time within which a petition for ju-
dicial review of such rule or action under this section
may be filed, and shall not postpone the effectiveness of
such rule or action.

(2) Action of the Administrator with respect to which
review could have been obtained under paragraph (1)
shall not be subject to judicial review in civil or criminal
proceedings for enforcement. Where a final decision by
the Administrator defers performance of any nondiscre-
tionary statutory action to a later time, any person may
challenge the deferral pursuant to paragraph (1).

“Modification” means any physical change in, or change in
the method of operation of, an existing facility which in-
creases the amount of any air pollutant (to which a standard
applies) emitted into the atmosphere by that facility or which
results in the emission of any air pollutant (to which a stan-
dard applies) into the atmosphere not previously emitted.”

40 C.F.R. § 60.14 Modification.

(a) Except as provided under paragraphs (e) and (f) of this
section, any physical or operational change to an existing fa-
cility which results in an increase in the emission rate to the
atmosphere of any pollutant to which a standard applies shall
be considered a modification within the meaning of section
111 of the Act. Upon modification, an existing facility shall
become an affected facility for each pollutant to which a stan-
dard applies and for which there is an increase in the emission
rate to the atmosphere.

(b) Emission rate shall be expressed as kg/hr of any pollutant
discharged into the atmosphere for which a standard is appli-
cable. The Administrator shall use the following to determine
emission rate:

*x* * * &

(e) The following shall not, by themselves, be considered
modifications under this part:

(e)(1) Maintenance, repair, and replacement which the Ad-
ministrator determines to be routine for a source category,
subject to the provisions of paragraph (c) of this section and
§ 60.15.

(e)(2) An increase in production rate of an existing facility, if
that increase can be accomplished without a capital expen-
diture on that facility. —

(e)(3) An increase in the hours of operation.

(e)(4) Use of an alternative fuel or raw material if, prior to the
date any standard under this part becomes applicable to that
source type, as provided by § 60.1, the existing facility was
designed to accommodate that alternative use. A facility shall
be considered to be designed to accommodate an alternative
fuel or raw material if that use could be accomplished under

18a

the facility’s construction specifications as amended prior to
the change. Conversion to coal required for energy considera-
tions, as specified in section 111(a)(8) of the Act, shall not be
considered a modification.

(e)(5) The addition or use of any system or device whose
primary function is the reduction of air pollutants, except
when an emission control system is removed or is replaced by
a system which the Administrator determines to be less envi-
ronmentally beneficial.

(e)(6) The relocation or change in ownership of an existing
facility.

(f) Speciai provisions set forth under an applicable subpart of
this part shall supersede any conflicting provisions of this sec-
tion.

(g) Within 180 days of the completion of any physical or op-
erational change subject to the control measures specified in
paragraph (a) of this section, compliance with all applicable
standards must be achieved.

(b) Definitions. All state plans shall use the following defini-
tions for the purposes of this section. Deviations from the fol-
lowing wording will be approved only if the state specifically
demonstrates that the submitted definition is more stringent,
or at least as stringent, in all respects as the corresponding
definitions below:

** * *

(21)(v) 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, pro-
vided the source owner or operator maintains and submits to
the reviewing authority, on an annual basis for a period of 5
years from the date the unit resumes regular operation, infor-
mation demonstrating that the physical or operational change
did not result in an emissions increase. A longer period, not to
exceed 10 years, may be required by the reviewing authority
if it determines such a period to be more representative of
normal source post-change operations.

x= * * *

(32) Representative actual annual emissions means the aver-
age rate, in tons per year, at which the source is projected to
emit a pollutant for the two-year period after a physical
change or change in the method of operation of a unit, (or a
different consecutive two-year period within 10 years after
that change, where the reviewing authority determines that
such period is more representative of normal source opera-

20a

tions), considering the effect any such change will have on
increasing or decreasing the hourly emissions rate and on pro-
jected capacity utilization. In projecting future emissions the
reviewing authority shall:

(i) Consider all relevant information, including but not
limited to, historical operational data, the company’s
own representations, filings with the State or Federal
regulatory authorities, and compliance plans under title
IV of the Clean Air Act; and

(ii) Exclude, in calculating any increase in emissions that
results from the particular physical change or change in
the method of operation at an electric utility steam gen-
erating unit, that portion of the unit’s emissions follow-
ing the change that could have been accommodated dur-
ing the representative baseline period and is attributable
to an increase in projected capacity utilization at the unit
that is unrelated to the particular change, including any
increased utilization due to the rate of electricity demand
growth for the utility system as a whole.
