     101  General Applicability



          This rule shall apply to any stationary source which

          would, if it did not comply with the limitations set

          forth in this rule, have the potential to emit air

          contaminants equal to or in excess of the threshold for

          a major source of regulated air pollutants or a major

          source of hazardous air pollutants (HAPs) and which

          meets one of the following conditions:



          101.1     In every 12-month period, the actual

                    emissions of the stationary source are less

                    than or equal to the emission limitations

                    specified in Section 301 below; or



          101.2     In every 12-month period, at least 90 percent

                    of the emissions from the stationary source

                    are associated with an operation limited by

                    any one of the alternative operational limits

                    specified in Section 601 below.



     102  Exemption Recordkeeping and Reporting for a Stationary

          Source with De Minimis Emissions: The recordkeeping and

          reporting provisions in Sections 400, 500 and 600 below

          shall not apply to a stationary source with de minimis

          emissions or operations as specified in either section

          102.1 or 102.2 below:



          102.1     In every 12-month period, the stationary

                    source emits less than or equal to the

                    following quantities of emissions:



               a.   5 tons per year of a regulated air pollutant

                    (excluding HAPs);



               b.   2 tons per year of a single HAP;



               c.   5 tons per year of any combination of HAPs;

                    and



               d.   20 percent of any lesser threshold for a

                    single HAP that the United States

                    Environmental Protection Agency (U.S. EPA)

                    may establish by rule.



          102.2     In every 12-month period, at least 90 percent

                    of the stationary source's emissions are

                    associated with an operation for which the

                    throughput is less than or equal to one of

                    the quantities specified in subsections (a)

                    through (h) below:



               a.   1,400 gallons of any combination of

                    solvent-containing materials but no more than

                    550 gallons of any one solvent-containing

                    material, provided that the materials do not

                    contain the following: methyl chloroform

                    (1,1,1 trichloroethane), methylene chloride

                    (dichloromethane), tetrachloroethylene

                    (perchloroethylene), or trichloroethylene;



               b.   750 gallons of any combination of

                    solvent-containing materials where the

                    materials contain the following: methyl

                    chloroform (1,1,1-trichloroethane), methylene

                    chloride (dichloromethane),

                    tetrachloroethylene (perchloroethylene), or

                    trichloroethylene, but not more than 300

                    gallons of any one solvent containing

                    material;               

                                        

                c.   4,400,000 gallons of gasoline dispensed from

                    equipment with Phase I and II vapor recovery

                    systems;



               d.   470,000 gallons of gasoline dispensed from

                    equipment without Phase I and II vapor

               h.   71,400,000 cubic feet of natural gas

                    combusted.



          Within 30 days of a written request by the District or

          the U.S. EPA, the owner or operator of a stationary

          source not maintaining records pursuant to Sections 400

          or 600 shall demonstrate that the stationary source's

          emissions or throughput are not in excess of the

          applicable quantities set forth in section 102.1 or

          102.2 above.



     103  Provision for Air Pollution Control Equipment: The

          owner or operator of a stationary source may take into

          account the operation of air pollution control

          equipment on the capacity of the source to emit an air

          contaminant if the equipment is required by Federal,

          State, or District rules and regulations or permit

          terms and conditions.  The owner or operator of the

          stationary source shall maintain and operate such air

          pollution control equipment in a manner consistent with

          good air pollution control practice for minimizing

          emissions.  This provision shall not apply after

          January 1, 1999, unless such operational limitation is

          federally-enforceable or unless the District Board

          specifically extends this provision and it is submitted

          to the U.S. EPA.  Such extension shall be valid unless,

          and until, the U.S. EPA disapproves the extension of

          this provision.



     104  Exemption, Stationary Source Subject to Rule 507,

          FEDERAL OPERATING PERMIT PROGRAM: This rule shall not

          apply to the following stationary sources:



          104.1     Any stationary source whose actual emissions,

                    throughput, or operation, at any time after

                    the effective date of this rule, is greater

                    than the quantities specified in Sections 301

                    or 601 below and which meets both of the

                    following conditions:



               a.   The owner or operator has notified the

                    District at least 30 days prior to any

                    exceedance that s/he will submit an

                    application for a Part 70 permit, or

                    otherwise obtain federally-enforceable permit

                    limits, and



               b.   A complete Part 70 permit application is

                    received by the District, or the permit

                    action to otherwise obtain

                    federally-enforceable limits is completed,

                    within 12 months of the date of notification.



               However, the stationary source may be immediately

               subject to applicable federal requirements,

               including but not limited to, a maximum achievable

               control technology (MACT) standard.



          104.2     Any stationary source that has applied for a

                    Part 70 permit in a timely manner and in

                    conformance with Rule 507, FEDERAL OPERATING

                    PERMIT PROGRAM, and is awaiting final action

                                        by the District and U.S. EPA.          104.3     Any stationary source required to obtain an

                    operating permit under Rule 507, FEDERAL

                    OPERATING PERMIT PROGRAM for any reason other

                    than being a major source.



          104.4     Any stationary source with a valid Part 70

                    permit.



          Notwithstanding sections 104.2 and 104.4, nothing in

          this section shall prevent any stationary source which

          has had a Part 70 permit from qualifying to comply with

          this rule in the future in lieu of maintaining an

          application for a Part 70 permit or upon rescission of

          a Part 70 permit if the owner or operator demonstrates

          that the stationary source is in compliance with the

          emissions limitations in Section 301 or an applicable

          alternative operational limit in Section 601.



     105  Exemption, Stationary Source with a Limitation on

          Potential to Emit: this rule shall not apply to any

          stationary source which has a valid operating permit

          with federally-enforceable conditions or other

          federally-enforceable limits limiting its potential to

          emit to below the applicable threshold(s) for a major

          source as defined in sections 206 and 207.



     106  Applicable Public Information Requests: Within three

          years of the effective date of Rule 507, FEDERAL

          OPERATING PERMIT PROGRAM, the District shall maintain

          and make available to the public upon request, for each

          stationary source subject to this rule, information

          identifying the provisions of this rule applicable to

          the source.



     107  Pre-Construction Permit Applicability: This rule shall

          not relieve any stationary source from complying with

          requirements pertaining to any otherwise applicable

          preconstruction permit, or to replace a condition or

          term of any preconstruction permit, or any provision of

          a preconstruction permitting program.  This does not

          preclude issuance of any preconstruction permit with

          conditions or terms necessary to ensure compliance with

          this rule.



200  DEFINITIONS



     All terms shall retain the definitions provided under Rule

     507, FEDERAL OPERATING PERMIT PROGRAM unless otherwise

     defined herein.



     201  Actual Emissions: The emissions of a regulated air

          pollutant from a stationary source for every 12-month

          period.  Verifiable continuous emission monitoring data

          determine actual emissions.  In the absence of

          verifiable continuous emissions monitoring data or

          source test data, the basis for determining actual

          emissions shall be: throughputs of process materials;

          throughputs of materials stored; usage of materials;

          data provided in manufacturer's product specifications,

          material volatile organic compound (VOC) content

          reports or laboratory analyses; other information

          required by this rule and applicable District, State

          and Federal regulations; or information requested in

          writing by the District.  All calculations of actual

          emissions shall use U.S. EPA, California Air Resources

          Board (CARB) or District approved methods, including

          emission factors and assumptions.

          stationary source 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 only if the limitation is federally-enforceable.



     210  Process Statement: An annual report on permitted

          emission units from an owner or operator of a

          stationary source certifying under penalty of perjury

          the following: throughputs of process materials;

          throughputs of materials stored; usage of materials;

          fuel usage; any available continuous emissions

          monitoring data; hours of operation; and any other

          information required by this rule or requested in

                    112(g)(2).  In case-by-case emissions

                    limitation determinations, the HAP shall be

                    considered a regulated air pollutant only for

                    the individual source for which the emissions

                    limitation determination was made.



     212  Twelve Month period: A period of twelve consecutive

          months determined on a rolling basis with a new

          12-month period beginning on the first day of each
