(b) Notwithstanding the plant size specified in Section I, Part
A.(1)(a) of this standard, any plant which emits, or has the
potential to emit, 250 tons per year or more of any air pollutant
subject to regulation under the Federal Clean Air Act; or

(c) Any physical change that would occur at a plant not otherwise
qualifying under Section I, Part A.(1) as a major plant, if the
change would constitute a major plant by itself.

(2) A major plant that is major for volatile organic compounds
shall be considered major for ozone.

Part B.

(1) "Major modification" means any physical change in or change
in the method of operation of a major plant that:

(a) would cause, by itself, a significant emissions increase from
the plant of any pollutant subject to regulation under the
Federal Clean Air Act.

(b) would result in a significant net emissions increase from the
plant of any pollutant subject to regulation under the Federal
Clean Air Act.

(2) Any net emissions increase that it significant for volatile
organic compounds shall be considered significant for ozone.

(3) A physical change or change in the method of operation shall
not include:

(a) Routine maintenance, repair and replacement;

(b) Use of an alternative fuel or raw material by reason of an
order under sections 2(a) and (b) of the Federal Energy Supply
and Environmental Coordination Act of 1974 (or any superseding
legislation) or by reason of a natural gas curtailment plan
pursuant to the Federal Power Act;

(c) Use of an alternative fuel by reason of an order or rule
under section 125 of the Federal Clean Air Act;

(d)Use of an alternative fuel at a steam generating unit to the
extent that the fuel is generated from municipal solid waste;

(e) Use of an alternative fuel or raw material by a plant which:

          (i) The plant 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 Federal Prevention of
     Significant Deterioration (PSD) Regulations or under
     federally approved regulations; or

          (ii) Theplant is approved to use anypermit issued under
     Federal PSD Regulationsor under federally approved State PSD
     Regulations;

(f) An increase in the hours of operation or in the production
rate, unless such change would be prohibited under any federally
enforceable permit condition which was established after January
6, 1975, pursuant to Federal PSD Regulations or under federally
approved state regulations;

(g) Any change in ownership at a plant.

Part C.

(1) "Net emissions increase" means the amount by which the sum of
the following exceeds zero:

(a) Any increase in actual emissions from a particular physical
change or change in method of operation at a plant; and,

(b) Any other increases and decreases in actual emissions at the
plant that are contemporaneous with the particular change and are
otherwise creditable.

(2) An increase or decrease in actual emissions is
contemporaneous with the increase from the particular change only
if it occurs between:

(a) The date five years before construction on the particular
change commences; and,

(b) The date that the increase from the particular change occurs.

(3) An increase or decrease in actual emissions is creditable
only if the Department has not relied on it in issuing a permit
for the plant under this section, which permit is in effect when
the increase in actual emissions from the particular change
occurs.

(4) An increase or decrease in actual emissions of sulfur
dioxide,  particulate matter or nitrogen oxides 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 emissions can be used to
evaluate the net emissions increase for PM-10.

(5) An increase in actual emissions is creditable only to the
extent that the new level of actual emissions exceeds the old
level.

(6) A decrease in actual emissions is creditable only to the
extent that:

(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) It is federally enforceable at and after the time that actual
construction on the particular change begins; and,

(c) It is approximately the same qualitatively significance for
public health and welfare as that attributed to the increase from
the particular change.

(7) An increase that results from the physical change at a plant
occurs 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.

Part D. "Potential to emit" means the maximum capacity of a plant
to emit a pollutant under its physical and operational design. 
Any physical or operational limitations on the capacity of the
plant 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
plant.

Part E. "Plant" means any building, structure, or installation
which emits or may emit any air pollutant subject to regulation
under the Federal Clean Air Act. 

Part F. "Building, structure, plant, or installation" mains 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). 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).

Part G. "Emissions unit" means any part of a plant which emits or
would have the potential to emit any pollutant subject to
regulation under the Federal Clean Air Act.

Part H. "Construction" means any physical change or change in the
method of operation (including fabrication, erection,
installation, demolition, or modification of an emissions unit)
which would result in a change in actual emissions.

Part I. "Commence" as applied to construction of a major plant or
major modification means that the owner or operator has all
necessary preconstruction approvals or permits and either has:

     (1) Begun, or caused to begin, a continuous program of
actual on- site construction of the plant, to be completed within
a reasonable time; or,

     (2) 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 plant to be completed within a
reasonable time.

Part J. "Necessary preconstruction approvals or permits" means
those permits or approvals required under federal air quality
control laws and regulations and those air quality control laws
and regulations which are part of the federally approved South
Carolina State Implementation Plan.

Part K. "Begin actual construction" means, in general, initiation
of physical on-site construction activities on an emissions unit
which are of a permanent nature.  Such activities include, but
are not limited to, installation of building supports and
foundations, laying underground pipework and construction of
permanent storage structures.  With respect to a change in
methods of operation, this term refers to those on-site
activities, other than preparatory activities, which mark the
initiation  of the change.

Part L. "Best available control technology" means an emissions
limitation (including a visible emission standard) based on the
maximum degree of reduction for each pollutant subject to
regulation under the Federal Clean Air Act which would be emitted
from any proposed major plant modification which the Department,
on a case-by-case basis, taking into account energy,
environmental, and economic impacts and other costs, determines
if achievable for such plant or modification through application
of production processes or available methods, systems, and
techniques including fuel cleaning or treatment or innovative
fuel combustion techniques including fuel cleaning or treatment
or innovative fuel 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 applicable standard
under Federal New Source Performance Standards or National
Emission Standards for Hazardous Air Pollutants (under 40 CFR
Part 60 and 61 as amended July 1, 1986).  If the Department
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.  Such standard shall, to the degree possible,
set forth the emissions reduction achievable by implementation of
such design, equipment, work practice or operation, and shall
provide for compliance by means which achieve equivalent results.

Part M.
(1) "Baseline concentration" means that ambient concentration
level which exits in the baseline area at the time of the
applicable baseline date.  A baseline concentration is determined
for each pollutant for which a baseline date is established and
shall include:

(a) The actual emissions representative of plants in existence on
the applicable baseline date, except as provided in Section I,
Part M.;

(b) The allowable emissions of major plants which commenced
construction before January 6, 1975, but were not in operation by
the applicable baseline date.

(2) The following will not be included in the baseline
concentration and will affect the applicable maximum allowable
increase(s):

(a) Actual emissions from any major plant on which construction
commenced after January 6, 1975; and,

(b) Actual emissions increases and decreases at any plant
occurring after the baseline date.

Part N.

(1) "Major source baseline date" means:

          (a) In the cae of particular matter and sulfur dioxide,
     January 6, 1975, and

          (b) In the case of nitrogen dioxide, February 8, 1988.

(2) "Minor Source baseline date" means the earliest date after
the trigger date on which a major stationary source or a
modification subject to State or Federal PSD Regulations submits
a complete application under the relevant regulations.  The
trigger date is:

          (a) In the case of particular matter and sulfur dioxide,
     August 7, 1977, and:

          (b) In the case of nitrogen dioxide, February 8, 1988.

(3) Any minor source baseline date established originally fopr
the TSP increments shall remain in effect and shall apply for
purposes of determining the amount of available PM-10 increments,
except that the Department may rescind any such minor source
baseline date where it can be shown, to the satisfaction of the
Department, that the emissions increase from the major stationary
source, or the net emissions increase from the major
modification, responsible for triggering that date did not result
in a significant amount of PM-10 emissions.



Part O.

"Baseline area" means any intrastate (and every part thereof)
designated as attainment or unclassifiable under section
107(d)(1)(D) or (E) of the Federal Clean Air Act in which the
major plant or major modification establishing the baseline date
would construct or would have an air quality impact equal to or
greater than 1 ug/m 3 (annual average) of the pollutant for which
the baseline date is established.

(2) Area redesignations under section 107 (d)(1)(D) or (E) of the
Federal Clean Air Act cannot intersect or be smaller than the
area of impact of any major stationary source or major
modification which:

          (a) Establishes a minor source baseline date; or

          (b) Is subject to 40 CFR 52.21 (July 1, 1993) or under
     regulations approved pursuant to 40 CFR 52.166 (July 1,
     1993).

(3) Any baseline area established originally for the TSP
increments shall remain in effect and shall apply for purposes of
determining the amount of available PM-10 increments, except that
such baseline area shall not remain in effect if the permit
authority rescinds the corresponding minor source baseline date
in accordance with Part N (1)(c) above.

Part P. "Allowable emissions" means the emissions rate of a plant
calculated using the maximum rated capacity of the plant (unless
the plant 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) The applicable standards as set forth in Federal New Source
Performance Standards and National Emission Standards for
Hazardous Air Pollutants;

(2) The South Carolina State Implementation Plan emissions
limitation, including those with a future compliance date; or

(3) The emissions rate specified as a federally enforceable
permit condition, including those with a future compliance date.

Part Q. "Secondary emissions" means emissions which would occur
as a result of the construction or operation of a major plant or
major modification, but do not come from the major plant or major
modification itself.  For the purpose of this section, secondary
emissions must be specific, well defined, quantifiable, and
impact the same general area as the plant or modification which
causes the secondary emissions.  Secondary emissions may include,
but are not limited to:

(1) Emissions from ships or trains coming to or from the new or
modified plant; and

(2) Emissions from any offsite support operation which would not
otherwise be constructed or increase its emissions as a result of
the construction or operation of the major plant or major
modification. 

Part R. "Innovative control technology" means any system of air
pollution control that has not been adequately demonstrated in
practice, but would have a substantial likelihood of achieving
greater continuous emissions reduction than any control system in
current practice or of achieving at least comparable reductions
at lower costs in terms of energy, economics, or nonair quality
environmental impacts.

Part S. "Fugitive emissions" means those emissions which could
not reasonably pass through a stack, chimney, vent, roof monitor,
or other functionally equivalent opening.

Part T.

(1) "Actual emissions" means the actual rate of emissions of a
pollutant from an emissions unit, as determined in accordance
with paragraphs (2)-(4) below.

(2) 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 plant operation.  The Department shall allow the use of a
different time period upon a determination that it is more
representative of normal plant 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.

(3) The Department may presume that plant-specific allowable
emissions for the unit are equivalent to the actual emissions of
the unit.

(4) 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.

Part U. "Complete" means, in reference to an application for a
permit, that the application contains all of the information
necessary for processing the application.

Part V.

(1) "Significant" means, in reference to a net emissions increase
or the potential of a plant to emit any of the following
pollutants, a rate of emissions that would equal or exceed any of
the following rates:

Part CC. "Adverse Visibility Impairment" means visibility
impairment which interferes with the management, protection,
preservation, or enjoyment of the Federal Class I area, including
interference with and impairment of the visitor's visual
experience.  This determination shall be made on a case-by-case
basis taking into account the extent, intensity, and duration of
the visibility impairment, the frequency and time of occurrence
of the impairment, the correlation between the time of the
visitors' use and access to the Federal Class I area, and the

the pollutant would occur as a result of a physical change or
change in the method of operation in the unit.

(4) For phased construction projects, the determination of best
available control technology shall be reviewed and modified as
appropriate at the latest reasonable time which occurs no later
than 18 months prior to commencement of construction of each
independent phase of the project.  At such time, the owner or
operator of the applicable plant may be required to demonstrate
the adequacy of any previous determination of best available
control technology for the plant.

Part B. Stack heights.

(1) The degree of emission limitation required for control of any
air pollutant under this standard shall not be affected in any
manner by:

(a) So much of the stack height of any plant as exceeds good
engineering practice, or

(2) Section IV, Part B.(1) of this standard shall not apply with
respect to stack heights in  existence before December 31, 1970,
or to dispersion techniques implemented before then.

Part C. Plant impact analysis.  The owner or operator of the
proposed plant or modification shall demonstrate that all
allowable emission increases from the proposed plant or
modification, in conjunction with all other applicable emissions
increases or reductions (including a secondary emissions), would
not cause or contribute to air pollution in violation of:

(1) Any national ambient air quality standard in any air quality
control region; or,

(2) Any applicable maximum allowable increase over the baseline
concentration in any area.

Part D. Air quality models.

(1) All estimates of ambient concentrations required under this
section shall be based on the applicable air quality models, data
bases, and other requirements specified in the "Guideline on Air
Quality Models" EPA 450/2-78-027R (Revised 1986), supplement A
(1987), supplement B(1993), and supplement C(1995), (U.S.
Environmental Protection Agency, Office of Air Quality Planning
and Standards, Research Triangle Park, N.C. 27711).  This
document is incorporated by reference .

(2) Where an air quality impact model specified in the "Guideline
on Air Quality Models" is inappropriate, the model may be
modified or another model substituted.  Such a change must be
subject to notice and opportunity for public comment under
Section IV, Part I, of this standard.  Written approval of the
Department and the Administrator of the EPA must be obtained for
any modification or substitution.  

Part E. Air Quality Analysis.

(1) (a) Preapplication analysis.  Any application for a permit
under this section shall contain an analysis of ambient air
quality in the area that the major plant or major modification
would affect for each of the following pollutants:

(i) For the plant, each pollutant that it would have the
potential to emit in a significant amount;

(ii) For the modification, each pollutant for which it would
result in a significant net emissions increase.

(b) With respect to any such pollutant for which no National
Ambient Air Quality Standard exists, the analysis shall contain
such air quality monitoring data as the Department determines is
necessary to assess ambient air quality for that pollutant in any
area that the emissions of that pollutant would affect. The
Department may, also, require visibility monitoring.

(c) With respect to any such pollutant (other than nonmethane
hydrocarbons) for which such a 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.  The Department may, also, require visibility
monitoring.

(d) In general, the continuous air quality monitoring data and
visibility data that are required shall have been gathered over a
period of at least one year and shall represent at least the year
preceding receipt of the application, except that, if the
Department determines that a complete and adequate analysis can
be accomplished with monitoring data gathered over a period
shorter than one year (but not to be less than four months), the
data that is required shall have been gathered over at least that
shorter period.

(e) For any application which becomes complete, except as to the
requirements of Section IV, Part E. (1) (c) and (d), between June
8, 1981, and February 9, 1982, the data that Section IV, Part E.
(1) (c) requires shall have been gathered over at least the
period from February 9, 1981, to the data the application becomes
otherwise complete, except that:

          (i) If the plant or modification would have been major for
     that pollutant under Federal PSD Regulations as in effect on
     June 19, 1978, any monitoring data shall have been gathered
     over at least the period required by those regulations.

          (ii) If the Department determines that a complete and
     adequate analysis can be accomplished with monitoring data
     over a shorter period (not to be less than four months), the
     data that Section IV, Part E. (1)(c) requires shall have
     been gathered over at least that shorter period.

          (iii) If the monitoring data would relate exclusively to
     ozone and would not have been required under Federal PSD
     Regulations as in effect on June 19, 1978, the Department
     may waive the otherwise applicable requirements of this
     Section IV Part E. (1) (e) to the extent that the applicant
     shows that the monitoring data would be unrepresentative of
     air quality over a full year.

(f) The owner or operator of a proposed plant or modification of
volatile organic compounds who satisfies all conditions of any
state or federal requirements of regulations related to non-
attainment areas may provide post-approval monitoring data for
ozone in lieu of providing preconstruction data as required under
Section IV, Part E.(1).

(2) Post-construction monitoring.  The owner or operator of a
major plant or major modification shall, after construction of
the plant or modification, conduct such ambient monitoring as the
Department determines is necessary to determine the effect
emissions from the plant or modification may have, or are having,
on air quality in any area.

(3) Operations of monitoring stations.  The owner or operator of
a major plant or major modification shall meet the requirements
of Quality Assurance Requirements for Prevention of Significant
Deterioration (PSD) Ambient Monitoring during the operation of
monitoring stations purposes of satisfying Section IV, Part E. of
this standard.

(4)  With respect to any requirements for air quality monitoring
of PM10 under Section IV, Part E, the owner or operator of the
source or modification shall use a monitoring method approved by
the U.S. Environmental Protection Agency and shall estimate the
ambient concentrations of PM10 using the data collected by such
approved monitoring method in accordance with estimating
procedures approved by the U. S. Environmental Protection Agency.

Part F.  Plant information.  The owner or operator of a proposed
plant or modification shall submit all information necessary to
perform any analysis or make any determination required under
this standard.

(1) With respect to a plant or modification to which Section IV,
Parts A., C., E., and G. of this standard apply, such information
shall include:

     (a) A description of the nature, location, design capacity,
and typical operating schedule of the plant or modification,
including specifications and drawings showing its design and
plant layouts;

     (b) A detailed schedule for construction of the plant or
modification.

     (c) A detailed description as to what system of continuous
emission reduction is planned for the plant or modification,
emission estimates, and any other information necessary to
determine that best available control technology would be
applied.

(2) Upon request of the Department, the owner or operator shall
also provide information on:

     (a) The air quality impact of the plant or modification,
including meteorological and topographical data necessary to
estimate such impact; and,

     (b) The air quality impacts, and the nature and extent of
any or all general commercial, residential, industrial, and other
growth which has occurred since August 7, 1977, in the area the
plant or modification would affect.

Part G.  Additional impact analyses.

(1) The owner or operator shall provide an analysis of the
impairment to visibility, soils and vegetation that would occur
as a result of the plant or modification and general commercial,
residential, industrial and other growth associated with the
plant or modification.  The owner or operator need not provide an
analysis of the impact on vegetation having no significant
commercial or recreational value.

(2) The owner or operator shall provide an analysis of the air
quality impact projected for the area as a result of general
commercial, residential, industrial and other growth associated
with the plant or modification.

Part H.

Additional requirements for plants impacting Federal Class I
areas.

(1) Notice to EPA.  The Department will transmit to the
Administrator of the Federal Environmental Protection Agency, a
copy of each permit application relating to a major plant or
major modification and provide notice to the Administrator of
every action related to the consideration of such permit.

(2) Federal Land Manager.  The Federal Land Manager and the
Federal official charged with direct 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 of the EPA, whether a proposed plant or
modification will have an adverse impact on such values.  When a
source is subject to this standard and may affect the visibility
of a Class I area, the following procedure will apply:

     (a) The Department will notify the Federal Land Manager in
writing within 30 days of receiving a permit application or
advance notification of application from a proposed source that
may impact a visibility protection area.  This notification will
take place at least 60 days prior to a public notice for public
hearing on the application.

     (b) The application must contain an analysis of the
potential impact of the proposed source on visibility.  The
Department will consider any analysis concerning visibility
impairment conducted by the Federal Land Manager if received
within 30 days of application receipt by the Federal Land
Manager.  If the Department does not totally concur with the
analysis of adverse visibility impairment resulting from the
proposed source, then the Department will provide in the public
notice for public hearing an explanation of its decision, or
provide notice where the explanation can be obtained.


(3) Denial-because of impact on air quality related values.  The
Federal Land Manager of any such lands may demonstrate to the
Department that the emissions from a proposed plant or
modification would have an adverse affect on the air quality-
related values (including visibility) of those lands,
notwithstanding that the change in air quality resulting from
emissions from such plant or modification would not cause or
contribute to concentrations which would exceed the maximum
allowable increases for a Class I area.  If the Department
concurs with such demonstration, then it shall not issue the
permit.

(4) Class I variances.  The owner or operator of a proposed plant
or modification may demonstrate to the Federal Land Manager that
the emissions from such plant or modification would have no
adverse impact on the air quality related values of any such
lands (including visibility), notwithstanding that the change in
air quality resulting from emissions from such plant 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 Department may issue the permit; provided,
that the applicable requirements of this section are otherwise
met. The permit will contain such emission limitations as may be
necessary to assure that emissions of sulfur dioxide and
particulate matter would not exceed the following maximum
allowable increases over baseline concentration for such
pollutants:

                                           Maximum allowable
                                           increase (micrograms
                                           per cubic meter)

     
Particulate matter:
PM-10, annual geometric mean.................17
PM-10, 24-hr. maximum........................30
Sulfur dioxide:
     Annual arithmetic mean................. 20
     24-hr. maximum........................  91
     3-hr. maximum......................... 325
Nitrogen dioxide:
     Annual arithmetic mean..................25

(5) Sulfur dioxide variance by Governor with Federal Land
Manager's concurrence.  The owner or operator of a proposed plant
or modification which cannot be approved under Section IV, Part
H.(4) of this standard may demonstrate to the Governor that the
plant or modification cannot be constructed by reason of any
maximum allowable increase for sulfur dioxide for a period of
twenty-four hours or less applicable to any Class I and, in the
case of Federal mandatory Class I areas, that a variance under
this clause would not adversely affect the air quality related
values of the area (including visibility).  The Governor, after
consideration of the Federal Land Manager's recommendation (if
any) and subject to his concurrence, may, after notice and public
hearing, grant a variance from such maximum allowable increase. 
If such variance is granted, the Department shall issue a permit  
   
to such plant or modification pursuant to the requirements of
Section IV, Part H.(7) of this standard: Provided, That the
applicable requirements of this standard are otherwise met.

(6) Variance by the Governor with the President's concurrence. 
In any case where the Governor recommends a variance in which the
Federal Land Manager does not concur, the recommendations of the
Governor and the Federal Land Manager shall be transmitted to the
President.  The President may approve the Governor's
recommendation if he finds that the variance is in the national
interest.  If the variance is approved, the Department shall
issue a permit pursuant to the requirements of Section IV, Part
H.(7) of this standard; provided, that the applicable
requirements of this standard are otherwise met.

(7) Emission limitations for Presidential or gubernatorial
variance.  In the case of a permit issued pursuant to Section IV,
Part H.(5) or (6) of this standard the plant or modification
shall comply with such emission limitations as may be necessary
to assure that such emissions would not cause or contribute to
concentrations which exceed the otherwise applicable maximum
allowable increases for periods of exposure of 24 hours or less
for more than 18 days, not necessarily consecutive, during any
annual period:

               Maximum Allowable Increase
               (Micrograms per cubic meter)

                                                  Terrain Areas
     Period of exposure                      Low       High
24-hr. maximum............................    36         62
 3-hr. maximum............................   130        221

Part I. Public participation.

(1) Within 30 days after receipt of an application to construct,
or any addition to such application, the Department shall advise 
the applicant of any deficiency in the application or in the
information submitted and transmit a copy of such application to
EPA.  In the event of such a deficiency, the date of receipt of
the application shall be, for the purpose of this section, the
date on which the Department received all required information.

(2) Within 1 year after receipt of a complete application, the
Department shall make a final determination on the application. 
This involves performing the following actions in a timely
manner:

     (a) Make a preliminary determination whether construction
should be approved, approved with conditions, or disapproved.

     (b) Make available in at least one location in each region
in which the proposed plant or modification would be constructed
a copy of all materials the applicant submitted, a copy of the
preliminary determination and a copy or summary of other
materials, if any, considered in making the preliminary
determination.

     (c) Notify the public, by advertisement in a newspaper of
general circulation in each region in which the proposed plant or
modification would be constructed, of the application, the
preliminary determination, the degree of increment consumption
that is expected from the plant or modification, and the
opportunity for comment at a public hearing as well as written
public comment.

(d) Send a copy of the notice of public comment to the applicant,
the Administrator of EPA, and to officials and agencies having
cognizance over the location where the proposed construction
would occur as follows:  The chief executives of the city and
county where the plant or modification would be located, any
comprehensive regional land use planning agency and any State,
Federal Land Manager, or Indian Governing Body whose lands may be
affected by emissions from the plant or modification.

(e) Provide opportunity for a public hearing for interested
persons to appear and submit written or oral comments on the air
quality impact of the plant or modification, alternatives to the
plant or modification, the control technology required, and other
appropriate considerations.

(f) Consider all written comments submitted within a time
specified in the notice of public comment and all comments
received at any public hearing(s) in making a final decision on
the approvability of the application.  No later than 10 days
after the close of the public comment period, the applicant may
submit a written response to any comments submitted by the
public.  The Department shall consider the applicant's response
in making a final decision.  The Department shall make all
comments available preconstruction information relating to the
proposed plant or modification.

(g) Make a final determination whether construction should be
approved, approved with conditions, or disapproved pursuant to
this section.

(h) Notify the applicant in writing of the final determination
and make such notification available for public inspection at the
same location where the Department made available preconstruction
information and public comments relating to the plant or
modification.

(i) Notify EPA of every action related to the consideration of
the permit.

(3) The requirements of Section IV, Part I. of this standard
shall not apply to any major plant or major modification which
Section III would exempt from the requirements of Section IV,
Parts C.,E., and G., but only to the extent that, with respect to
each of the criteria for construction approval under the South
Carolina Implementation Plan and for exemption under Section III,
requirements providing the public with at least as much
participation in each material determination as those of Section
IV, Part I. have been met in the granting of such construction
approval.

Part J. Plant obligation.

(1) Any owner or operator who constructs or operates a major
plant or major modification not in accordance with the
application submitted pursuant to this section or with the terms
of any approval to construct, or any owner or operator of a major
plant or major modification subject to this section who begins
actual physical construction after the effective date of these
regulations without applying for and receiving approval
hereunder, shall be subject to appropriate enforcement action.

(2) Approval to construct shall become invalid if construction is
not commenced within 18 months after receipt of such approval, if
construction is discontinued for a period of 18 months or more,
or if construction is not completed within a reasonable time. 
The Department may extend the 18-month period upon a satisfactory
showing that an extension is justified.  This provision does not
apply to the time period between construction of the approved
phases of a phased construction project; each phase must commence
construction within 18 months of the projected and approved
commencement date.

(3) Approval to construct shall not relieve any owner or operator
of the responsibility to comply fully with applicable provisions
of the State Implementation Plan and any other requirements under
local, State, or Federal law.

(4) At such time that a particular plant or modification becomes
a major plant or major modification solely by virtue of a
relaxation in any federally enforceable limitation which was
established after August 7, 1980, on the capacity of the plant or
modification otherwise to emit a pollutant, such as a restriction
on hours of operation, then the requirements or Section IV of
this standard shall apply to the plant or modification as though
construction had not yet commenced on the plant or modification.

Part K. Innovative control technology.

(1) An owner or operator of a proposed major stationary plant or
major modification may request the Department in writing to
approve a system of innovative control technology.

(2) The Department may, with the consent of the Governor(s) of
other affected state(s), determine that the plant or modification
may employ a system of innovative control technology if;

     (a) The proposed control system would not cause or
contribute to an unreasonable risk to public health, welfare, or
safety in its operation or function;

     (b) The owner or operator agrees to achieve a level of
continuous emissions reduction equivalent to that which would
have been required under Section IV, Part A.(2) by a date
specified by the Department.  Such date shall not be later than 4
years from the time of startup or 7 years from the permit
issuance;

     (c)  The plant or modification would meet the requirements
of Section IV, Part A. and Part C. based on the emissions rate
that the plant employing the system of innovative control
technology would be required to meet on the date specified by the
Department.

     (d) The plant or modification would not before the date
specified by the Department:

          (i) Cause or contribute to a violation of an applicable
     national ambient air quality standard; or,

          (ii) Impact any Class I area; or,

          (iii) Impact any area where an applicable increment is known
     to be violated; and

(e) All other applicable requirements including those for public
participation have been met.

(3) The Department shall withdraw any approval to employ a system
of innovative control technology made under this section if:

     (a) The proposed system fails by the specified date to
achieve the required continuous emissions reduction rate; or

     (b) The proposed system fails before the specified date so
as to contribute to an unreasonable risk to public health,
welfare, or safety; or

     (c) The Department decides at any time that the proposed
system is unlikely to achieve the required level of control or to
protect the public health, welfare, or safety.

(4) If a plant or modification fails to meet the required level
of continuous emission reduction within the specified time period
or the approval is withdrawn in accordance with Section IV, Part
K.(3) the Department may allow the plant or modification up to an
additional 3 years to meet the requirement for the application of
best available control technology through use of a demonstrated
system of control.
