                         STANDARD NO. 1
               EMISSIONS FROM BURNING OPERATIONS



SECTION I - VISIBLE EMISSIONS

A. Existing Sources

     No one shall discharge to the ambient air from any existing
source constructed prior to February 11, 1971, smoke which exceeds
an opacity of forty (40) percent.  For a total of six (6) minutes
in one hour or twenty-four (24) minutes in a twenty-four (24) hour
period, forty (40) percent opacity may be exceeded for soot
blowing; but shall in no case exceed an opacity of sixty (60)
percent.

B. New Source

     No one shall discharge to the ambient air from any source
constructed on or after February 11, 1971, smoke which exceeds an
opacity of twenty (20) percent. 

C. Special Provisions

     The opacity standards set forth above do not apply during
startup or shutdown.  Owners and operators shall, to the extent
practicable, maintain and operate any source including associated
air pollution control equipment in a manner consistent with good
air pollution control practices for minimizing emissions.  In
addition, the owner or operator shall maintain a log of the time,
magnitude, duration and any other pertinent information to
determine periods of startup and shutdown and make available to the
Department upon request.

D. Test Method

     The method which is approved by the department for determining
compliance with opacity limitations under this section is EPA
Reference Method 9 (40 CFR 60, Appendix A, as revised July 1,
1986). Alternate methods may be utilized only if approved in
advance by the Department and by the Environmental Protection
Agency.

SECTION II - PARTICULATE MATTER EMISSIONS

A. Allowable Discharge

     The allowable discharge of particulate matter resulting from
fuel burning operations shall be limited to the values obtained by
use of Figure 1 and/or Part B.  (For the purpose of determining
heat input, total equipment capacity refers to total equipment
capacity discharging through each stack.  If a boiler has more than
one(1) stack the total rated capacity will be the boiler rated
capacity discharging to these stacks).  Interpolation of Figure 1
for fuel burning operation of 1300 million BTU per hour heat input
and larger shall be accomplished by use of the equation:

          E = 57.54 P-0.637
where     E = the allowable emission rate in pounds per million   
           BTU heat input,
and       P = million BTU heat input per hour  


B. Special Provisions

     All fuel burning operations of 10 million BTU per hour heat
input and smaller constructed prior to February 11, 1971, shall be
allowed 0.8 pounds per million BTU input.

[See figure 1. as shown on p. 5/1-2 of regs]

SECTION III - SULFUR DIOXIDE EMISSIONS

A. General

     The maximum allowable discharge of sulfur dioxide (SO 2) from
fuel burning operations shall be in accordance with a system of
priorities as specified hereinafter in paragraph B.  The
classifications shall be delineated on a county basis. The maximum
allowable discharge for the various classes is specified in
paragraph C of this Section.

B. Classifications

     1.   The class into which a given county falls has been determined
     by mathematical atmospheric diffusion models and other methods
     which evaluate those factors which necessitates limits on
     sulfur dioxide emissions.  These factors included but were not
     limited to: (1) total sulfur dioxide emissions; (2) spatial
     distribution of sulfur dioxide sources; (3) effects of single,
     large sources; (4) existing, measured air quality; (5)
     topographical features of the county; (6) contributions to
     background levels due to sources outside the county being
     considered; (7) population density.

     2.   The assigned classifications will be reviewed periodically at
     intervals not to exceed three years, and changes will be made
     as required.  When a county is assigned to a more restrictive
     class, individual compliance schedules will be established in
     such a way that reasonable time will be allowed for the
     sources to make necessary changes in equipment and/or fuel
     contracts.

3. The following classifications are assigned:

          Class I        -    Charleston County
          Class II       -    Aiken County - Anderson County
          Class III      -    All others

C. Allowable discharges

Sulfur dioxide emissions from fuel burning sources located in
various counties will not exceed the following limits:

1. Counties in Class I
                             
                              Maximum Allowable Emissions
Rated Source Size               (lb SO2/million BTU Input

Up to and including                      3.5
10 million BTU/hr

Greater than 10 million BTU/hr           2.3






2. Counties in Class II

                                   Maximum Allowable Emissions
Rated Source Size                  (lb SO 2/million BTU Input

Up to 1000 million BTU/hr                    3.5

1000 million BTU/hr and larger               2.3



3. Counties in Class III

                                   Maximum Allowable Emissions
Rated Source Size                  (lb SO2/million BTU Input)
-----------------                  ---------------------------
All                                          3.5


D. Special Provisions
     
     If it can be demonstrated to the satisfaction of the Board
that ambient air standards will not be contravened by a source,
alone or in combination with other sources, a greater allowance for
sulfur dioxide discharges may be made on a case by case basis.

          violations of the provisions of Section I.

If no reportable incidents occur during a quarter, a report is also
required indicating as such.

     2.   Alternative data reporting procedures may be allowed if the
     owner or operator shows, to the satisfaction of the
     Department, that these procedures are at least as accurate as
     those described.

     3.   The owner or operator shall maintain a file of all information
     contained in the quarterly reports, calibration data for the
     opacity monitoring system(s), and all other data generated by
     the continuous opacity monitoring system(s), for a minimum of
     two years from the date of submission of such reports or
     collection of such data.  The information contained on file
     must be made available for review by Department personnel upon
     request.

C. Exemption from Reporting Requirements

     A temporary exemption from the opacity monitoring and
reporting requirements of this Section may be granted during any
period of monitoring system(s) malfunction, provided the owner or
operator shows, to the satisfaction of the Department, that the
malfunction was unavoidable and is being repaired as expeditiously
as possible.     

D. Equipment Performance Specifications

     The continuous opacity monitoring system(s) required by
Paragraph A.1. of this Section (for fossil fuel fired steam
generators) shall conform  with the performance specifications set
forth in 40 CFR, Part 60, Appendix B, Performance Specification 1
as revised July 1, 1986 which is incorporated by reference as a
part of this Standard except that where the term "Administrator" is
used the term "Department" shall be substituted.  In addition, the
opacity monitoring system(s) shall complete a minimum of one cycle
of operation for each successive 10-second period; be installed
such that representative measurements of opacity from the affected
steam generator are obtained; and have an instrument span of
approximately 80 percent opacity.
 
     The owner or operator shall record the zero and span drift in
accordance with method prescribed by the manufacturer of such
opacity monitoring system(s); subject the system(s) to the
manufacturer's recommended zero and span check at least once daily
unless the manufacturer has recommended adjustments at shorter
intervals, in which case such recommendations shall b followed;
adjust the zero and span whenever the 24-hour zero drift or 24-hour
calibration drift limits of 40 CFR, Part 60, Appendix B,
Performance Specification 1 as revised July 1, 1986 are exceeded;
adjust the opacity monitoring system(s) purchased prior to
September 11, 1974, whenever the 24-hour zero drift or 24-hour
calibration drift exceeds 4 percent opacity for those generators
constructed prior to February 11, 1971 and 2 percent opacity for
those generators constructed after February 11, 1971.

     The monitoring systems must be approved by this agency prior
to installation.

E. Monitor Location

     When the effluents from two or more affected steam generators
of similar design and operating characteristics are combined before
released to the atmosphere, the opacity monitoring system(s) shall
be installed on the combined effluent.  When the affected steam
generators are not of similar design and operating characteristics,
or when the effluent from one affected steam generator is released
to the atmosphere through more than one point, the owner or
operator shall apply for an alternate procedure to comply with the
requirements of this Section.

F. Exemptions from Monitoring Requirements

     Whenever the requirements for continuous opacity monitoring
cannot be implemented by the owner or operator due to physical
plant limitations, extreme economic burden, or infrequent steam
generator operation of less than 30 days per year, or when the
specified monitoring procedure would not provide accurate opacity
determinations, alternate monitoring and reporting requirements may
be approved on a case-by-case basis provided the owner or operator
submits a written request to the Department which includes, but is
not limited to:

          1. The basis or reason(s) that alternate requirements are 
     necessary;

          2. A proposal of the alternate monitoring and reporting
     requirements; and,

          3. Any other information needed by the Department to make a
