Part B.  General Applicability

1. This standard will apply to existing sources statewide except
in the following counties: Anderson, Bamberg, Barnwell,
Chesterfield, Darlington, and Hampton.

2. This standard will apply to plants described under one of the
Parts of Section II when such a plant has potential emissions of
VOC more than 550 pounds (250 kilograms) in any one day (nominal
size - 100 tons per year) or more than 150 pounds (68 kilograms)
in any one hour.  This paragraph does not apply to Part N.

3. A plant having an existing process which was not required to
be regulated due to plant size will be subject to the Regulation
when that plant increases emissions sufficiently to meet the
applicability requirements regardless of the time frame. 
Conversely, a source which is subject to the requirements of the
Regulation, but which decreases emissions sufficiently so that
their total potential emissions are below the applicability
requirements, may petition the Department for relief from the
emission limits of the Regulation.  Approval of the petition will
be based, in part, on showing that the reductions are not
temporary and a consent to be permitted at the reduced level.

4. Further applicability requirements or limitations may be
listed under the individual Parts of Section II.

Part C. Alternatives and Exceptions to Control Requirements

1. Alternative Controls
     
     a. If the owner or operator of a source of volatile organic
compounds regulated by this Standard can demonstrate that
compliance with Section II would not be feasible, he may petition
the Department to allow the use of alternative operational and/or
equipment controls for the reduction of volatile organic compound
emissions of such source.  Petition must be made for each source
within a given plant and nothing herein should be interpreted as
permitting a source regulated by this Standard to exceed
emissions limits for that source as given in Section II.  The
petition must be submitted in writing to the Department and must
contain:

                    (i) the name and address of the company and the name
          address and telephone number of a company officer over
          whose signature the petition is submitted; and,

                    (ii) a description of all operations conducted at the
          location to which the petition applies and the purpose
          that the volatile organic compounds emitting equipment
          serves within the operations; and,

                    (iii) reference to the specific operational and/or
          equipment controls under Section II for which
          alternative operational and/or equipment controls are
          proposed; and,

                    (iv) a detailed description of the proposed alternative
          operational and/or equipment controls, the magnitude of
          volatile organic compound emission reduction which will
          be achieved, and the quantity and composition of
          volatile organic compounds which will be emitted if the
          alternative operational and/or equipment controls are
          instituted; and,

                    (v) a schedule for installation and/or institution of
          the alternative operational and/or equipment controls
          in conformance with Section II.

     b. The  Department may approve a Petition for Alternative
Control if:

          (i) the petition is submitted in accordance with
Paragraph a above; and,

          (ii) the Department determines that the petitioner
cannot comply with Section II below because of technological
infeasibility (considering costs); and,

          (iii) the petition contains a schedule for achieving
and maintaining reduction of volatile organic compound emissions
to the maximum extent feasible and as expeditiously as
practicable; and,

          (iv) a nuisance condition will not result from
operation of the source as proposed in the Petition; and,

          (v) the alternative control approach must assure
control levels system at least as stringent as those listed in
the appropriate part of Section II; and

          (vi) the petition is approved by USEPA as a source-
specific State Implementation Plan revision.


     2. Alternative Emission Limitations

     a. If the owner or operator of a source of volatile organic
compounds regulated by this standard can demonstrate that
compliance with applicable portions of Section II 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 Section II.
     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.

     b.  Exceptions granted under this part are not effective

          device; or,

                    (ii) an incineration system that oxidizes at least 90
          percent of the nonmethane volatile organic compounds (VOC
          measured as total combustible carbon) to carbon dioxide
          and water.

                    (iii) an alternative volatile organic compound emission
          reduction system certified by the owner or operator to
          have at least a 90.0 percent reduction efficiency,
          measured across the control system, that has been
          approved by the Department.

gasoline terminal subject to this Part unless:

     a. the bulk gasoline terminal is equipped with a vapor control
system, properly installed, in good working order, in operation and
consisting of one of the following:

                    (i) an adsorber or condensation system which may not
          allow mass emissions of VOC's to exceed 4.7 grains per
          gallon (80 milligrams per liter) of gasoline loaded; or,

                    (ii) a vapor collection system which directs all vapors
          to a fuel gas system; or,

                    (iii) alternative controls as allowed under Section I,
          Part C.

     b. all displaced vapors and gases are vented only to the vapor
control system; and,

     c. a means is provided to prevent liquid drainage from the
loading device when it is not in use or to accomplish complete
drainage before the loading device is disconnected; and,

     d. all loading and vapor lines are equipped with fittings
which make vapor-tight connections and which close automatically
when disconnected.

Sources affected by this Part may not:

          a. allow avoidable visible liquid leaks during loading or
     unloading operations; or,

          b. allow the pressure in the vapor collection system to exceed
     the gasoline tank truck pressure relief settings; or,

          c. allow gasoline to be discarded in sewers or stored in open
     containers or handled in any manner that would result in
     evaporation.

3. Compliance Schedules

     a. The owner or operator of a volatile organic compound source
subject to this Part shall comply with a Schedule 1 of Section I,
