C. Case-by-Case Exceptions to Provisions of Part B.

     1.   If the owner or operator of a source of total reduced sulfur
     compounds regulated by this standard can demonstrate that
     compliance with applicable portions of Part B would not be
     economically feasible, the Department may, on a case-by-case
     basis, allow emission limitations less stringent than those
     required by applicable parts of Part B.

          All data pertinent to the showing of economic infeasibility
     must accompany a petition for this relief; and shall include
     a present value analysis showing economic infeasibility.

     2.   Exceptions granted under this part are not effective until
     submitted to and approved by the Administrator of United
     States Environmental Protection Agency as a revision of the
     Implementation Plan for Control of Designated Pollutants,

D. Monitoring, Recordkeeping and Reporting

1. The owner/operator shall:

               a.   calibrate, maintain and operate continuous monitoring
          equipment to monitor and record the concentration of
          TRS emissions on a dry basis and the percent of oxygen
          by volume on a dry basis in the gases discharged into
          the atmosphere from any lime kiln, recovery furnace,
          digester system, multiple-effect evaporator system, or
          condensate stripper system, except where these gases
          are subjected to a minimum temperature of 1200oF for at
          least 0.5 seconds in an incinerator or other device
          which does not generate TRS.   The location of each
          monitoring system must be approved by this Department.

               b.   install, calibrate, maintain and operate a monitoring
          device which measures the combustion temperature at the
          point of incineration of effluent gases which are
          emitted from any lime kiln, recovery furnace, digester
          system, multiple-effect evaporator system, or
          condensate stripper system unless TRS monitors are
          required in paragraph (a).  The monitoring device is to
          be certified by the manufacturer to be accurate within
          +1 percent of the temperature being measured.

               c.   calibrate, maintain and operate continuous monitoring
          equipment for any smelt dissolving tank,

                         (i)  for the continuous measurement of the pressure
               loss of the gas stream through the control
               equipment.  The monitoring device is to be
               certified by the manufacturer to be accurate to
               within a gauge pressure of +- 2 inches;

               (ii) for the continuous measurement of the scrubbing 
     liquid supply pressure to the control equipment.  The
     monitoring device is to be certified by the manufacturer to
     be accurate within + 15 percent of design scrubbing liquid
     supply pressure.  The pressure sensor or tap is to be
     located close to the scrubber liquid discharge point.  The
     Department may be consulted for approval of alternative
     locations;

Continuously monitored operating and/or stack parameters may be
used as substitutes for TRS monitors provided that it is
demonstrated to the satisfaction of this Department that a
correlation exists between the monitored parameter and TRS
concentration and the other requirements in paragraph D(1) are
fulfilled.  Alternative equivalent methods of monitoring must be
approved by this Department and EPA.

     2.   Any owner or operator subject to the provisions of this
     section shall:

               a.   calculate and record on a daily basis 12-hour average 
          TRS concentrations for the two consecutive periods of
          each operating day.  Each 12-hour average shall be
          determined as the arithmetic mean of the appropriate 12
          contiguous 1-hour average total reduced sulfur
          concentrations provided by each continuous monitoring
          system installed under paragraph D (1)(a);

               b.   calculate and record on a daily basis 12-hour average
          oxygen concentrations for the two consecutive periods
          of each operating day for the recovery furnace and lime
          kiln.  These 12-hour averages shall correspond to the
          12-hour average TRS concentrations under paragraph
          D(2)(a) and shall be determined as an arithmetic mean
          of the appropriate contiguous 1-hour average oxygen
          concentrations provided by each continuous monitoring
          system installed under paragraph D (1)(a);

               c.   correct all 12-hour average TRS concentrations to 10
          volume percent oxygen, except that all 12-hour average
          TRS concentrations from a recovery furnace shall be
          corrected to 8 volume percent using the following
          equation:

                              C corr = C uncorr  x  (21-X/21-Y)

          where:
                              C corr  = the concentration corrected for oxygen.

                              C uncorr   = the concentration uncorrected for
               oxygen.

                              X   =  the volumetric oxygen concentration in 
               percentage
                                                  to be corrected to (8 percent for
                         recovery 
                                                  furnaces and 10 percent for lime kilns, 
                                                  incinerators, or other devices).
     
                              Y   =  the measured 12-hour average volumetric
                oxygen concentration.

     3.   Each owner or operator required to install a continuous 
     monitoring system shall submit a written report of excess
     emissions (as defined in applicable subparts) to the
     Department for every calendar quarter unless specified on a
     more frequent cycle by the Department.  All quarterly
     reports shall be postmarked by the 30th day following the
     end of each calendar quarter and shall include the following
     information:

               a.   for emissions from any recovery furnace, periods of
          excess emissions are all 12-hour average TRS
          concentrations above 20 ppm by volume for old design
          recovery furnaces, 5 ppm by volume for new design
          recovery furnaces and above 25 ppm by volume for cross
          recovery furnaces;

     b.   for emissions from any lime kiln, periods of excess 
                    emissions are all 12-hour average TRS concentrations
          above 20 ppm by volume;

               c.   for emissions from any digester system, multiple-effect
          evaporator system, or condensate stripper system
          periods of excess emissions are:

                    (i)  all 12-hour average TRS concentrations above 5 ppm 
               by volume unless the provisions of D(1)(a) apply;

                    (ii) all periods in excess of 5 minutes and their 
          duration during which the combustion temperature is
          less than 1200oF if the gases are combusted in an
          incinerator or other device which does not generate
          TRS.

4. The Department will consider periods of excess emissions
reported under Subpart D(3) of this section to be indicative of a
violation if:

               a.   the number of 12 hour exceedances from recovery
          furnaces is greater than 1% of the total number of
          contiguous 12 hour periods in a quarter (excluding
          periods of startup, shutdown, or malfunction and
          periods when the recovery furnace is not operating).

               b.   the number of excess emissions from lime kiln exceeds
          2% of the total number of possible contiguous periods
          of excess emissions in a quarter (excluding periods of
          startup, shutdown, or malfunction and periods when the
          lime kiln is not operating).

               c.   the number of 12 hour exceedances from incinerators is
          greater than 2% of the total number of contiguous
          periods in a quarter (excluding periods of startup,
          shutdown, or malfunction and periods when the
          incinerator is not operating).

               d.   the Department determines that the affected equipment,
          including air pollution control equipment, is not
          maintained and operated in a manner which is consistent
          with good air pollution control practice for minimizing
          emissions during periods of excess emissions.

1st Revision:  MAR 16, 1989       JUL 02, 1990       55 FR 27226 SECTION XIII - SOURCE TEST REQUIREMENTS A.   The owner or operator required to comply with Section XII
     above shall conduct such tests as required by the Department
     in order to demonstrate compliance with this Standard. The
     test methods and procedures used shall be approved EPA test
     methods or such alternative methods as approved by the
     Department prior to testing.

          Tests shall be conducted while the source is operating at
     the maximum production rate or other production rate or
     operating conditions which would result in the highest
     emissions.  Any production rate less than rated capacity may
     result in production limitations on the permits.

          All tests shall be made by, or under the direction of, a
     person qualified by training and/or experience in the field
     of air pollution testing.

          Asphalt plants will be required to produce "surface mix"
     during compliance source testing.  "Surface mix" is hot laid
     asphaltic concrete surface courses (except sand asphalt
     surface mix) as defined in Section 403 of the 1973 edition
     of the South Carolina State Highway Department's "Standard
     Specifications for Highway Construction" manual.

          The Department may, at its discretion, waive this
     requirement if sufficient evidence indicates that less than
     25% of the plant's total annual production is surface mix.

     B.   Any source owner or operator proposing to conduct tests in
     accordance with paragraph A. above shall notify the
     Department in the manner set forth below of the intent to
     test, not less than two weeks before the proposed initiation
     of the tests so the Department may observe the test if it
     desires to do so.

          Notification shall include the following minimum
     information:

               1.   the purpose of the proposed test.

               2.   a description of the source to be tested.

               3.   a description of the test procedures, equipment, and
          sampling sites.

               4.   a timetable, setting forth the dates on which the
          testing will be started and concluded.

     C.   The final test reports must be submitted no later than 30
     days after completion of on-site testing, containing as a
     minimum, the following supporting information.

               1.   process weight rates (lb/hr.)

               2.   process design and load rates at which the test was
          conducted.

               3.   procedure used for determining process weight rates.

               4.   calculations used to determine process weight rates.

               5.   signature of responsible company official.

     D.   The owner or operator proposing a source test under the
     provisions of this section shall be responsible for
     providing:

               1.   sampling ports, pipes, lines, or appurtenances for the
          collection of samples and data required by the test
          procedure.

               2.   safe access to the sample and data collection
          locations.

               3.   light, electricity, and other utilities required for
          sample and data collection.

     E.   Any proposed deviations from the procedures and requirements
     stated above must be thoroughly explained and must be
     approved by this Department prior to testing.  Failure to
     observe any of these procedures or requirements may be
     grounds for not accepting the tests.
