South Carolina State Implementation Plan

SOUTH CAROLINA 
         DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL
                   AIR POLLUTION REGULATIONS 
                     REGULATION NUMBER 62.3
                     AIR POLLUTION EPISODES SECTION I - EPISODE CRITERIA Conditions justifying the proclamation of any stage of an air
pollution episode shall be deemed to exist whenever the
Commissioner determines that the accumulation of air pollutants in
any place is attaining or has attained levels which could, if such
levels are sustained or exceeded, lead to substantial threat to the
health of persons.  The appropriate episode stage will be declared
on a region basis, as dictated by air quality monitoring.  Adverse
air quality need not be regionwide to trigger control actions; the
appropriate episode stage will be declared for an entire Air
Quality Control Region when any monitoring site within the region
records ambient air quality in excess of that designated in the
criteria.  In making this determination, the Commissioner will be
guided by the criteria listed below:

               1.   FORECAST - This level will normally be activated when an
          Air Stagnation Advisory (ASK) is issued for any part of
          South Carolina by the Columbia Forecast Office of the
          National Weather Service. If continuous air monitoring
          equipment indicates an upward trend in pollutant
          concentrations, the Commissioner may request that the
          National Weather Service issue an ASK, even though
          meteorological factors do not appear critical.  In the
          absence of an ASA, the Commissioner may, at his
          discretion, declare this level when it is in the best
          interest of public health and welfare.

               2.   WATCH - This level will be activated when continuous air
          quality monitoring indicates that one of the following
          pollutant concentrations has been reached:

                    PM10 - 350 ug/m3, 24-hour average;

                    SO2 - 400 ug/m3 (0.15 p.p.m.), 24-hour average;

                    O3 (Ozone) - 400 ug/m3 (0.2 p.p.m.), 1-hour average;

                    and meteorological conditions are such that the pollutant
          concentrations can be expected to remain at the above
          levels for twelve (12) hours or more, or increase, or in
          the case of ozone, the situation is likely to recur
          within the next 24 hours unless control actions are
          taken.
 
               3.   ALERT - This level indicates that air quality is
          continuing to deteriorate and that additional control
          actions are necessary. An alert will be declared when
          monitoring indicates that one of the following pollutant
          concentrations has been reached:

                              PM10 - 420 ug/m3, 24-hour average

                              SO2 - 800 ug/m3 (0.3 p.p.m.), 24-hour average;

                              O3 (Ozone) - 800 ug/m3 (0.4 p.p.m.), 1-hour average;

                    and meteorological conditions are such that pollutant
          concentrations can be expected to remain at the above
          levels for twelve (12) hours or more, or increase, or in
          the case of ozone, the situation is likely to recur
          within the next 24 hours unless control actions are
          taken.

               4.   EMERGENCY - The primary objective of this plan is to
          prevent this level from ever being reached; however,
          should this level be reached the most stringent control
          actions are necessary.  An emergency will be declared
          when monitoring indicates that one of the following
          pollutant concentrations has been reached:

                              PM10 - 500 ug/m3, 24-hour average;

                              SO2 - 1600 ug/m3 (0.6 p.p.m.), 24-hour average;

                              O3 (Ozone) - 1000 ug/m3 (0.5 p.p.m.), 1-hour
               average;

                    and meteorological conditions are such that this
          condition can be expected to continue for twelve (12)
          hours or more, or increase, or in the case of ozone, the
          situation is likely to recur within the next 24 hours
          unless control actions are taken.

               5. TERMINATION - Once declared, any level reached by
          application of these criteria will remain in effect until
          the criteria for that level are no longer met.  At such
          time, the next lower level will be assumed. SECTION II - EMISSION REDUCTION REQUIREMENTS Operators of plants emitting 100 tons per year or more of a
single pollutant, and located in a nonattainment county or a county
with a nonattainment area, are required to submit written plans for
meeting the required reductions of pollutants for which the county
is in nonattainment. These plans must identify the air pollutant
source, the approximate amount of reduction of pollutants and a
brief description of the manner in which the reduction will be
achieved during each level.  Sources of particulate matter and
sulfur dioxide have been subject to this requirement since 1972. 
Sources of volatile organic compounds must comply with this
requirement by July 1, 1980.
