100 GENERAL

    101  PURPOSE:  The purpose of this rule is to allow owners or
         operators of specified stationary sources that would
         otherwise be major stationary sources to request and accept
         federally enforceable emissions limits sufficient to enable
         the sources to be considered synthetic minor stationary
         sources.

         A synthetic minor stationary source is not subject to Rule
         207, TITLE V - FEDERAL OPERATING PERMIT PROGRAM unless it
         is subject to that rule for a reason other than being a
         major stationary source.  A synthetic minor stationary
         source is subject to all applicable federal requirements
         for non-major stationary sources and to all federally
         enforceable conditions and requirements pursuant to this
         rule.  In addition, a synthetic minor stationary source is
         subject to all applicable State and District rules,
         regulations, and other requirements.
         
    102  APPLICABILITY:  This rule applies to any major stationary
         source located within the District for which the owner or
         operator requests, and would be able to comply with,
         federally enforceable limitations or conditions that
         qualify the source to be a synthetic minor source, as
         defined herein.  This rule shall not apply to any
         stationary source that is subject to District Rule 207,
         TITLE V - FEDERAL OPERATING PERMIT PROGRAM for a reason
         other than being a major stationary source.

200 DEFINITIONS

All terms shall retain the definitions provided under District Rule
207, TITLE V - FEDERAL OPERATING PERMIT PROGRAM, as applicable,
unless otherwise defined herein.

    201  FEDERALLY ENFORCEABLE:  All limitations and conditions
         which are directly enforceable by U.S. EPA, including:
         201.1   District requirements developed pursuant to 40 CFR
                 Parts 60 (NSPS), 61 (NESHAP), 63 (NESHAP), 70
                 (Title V Operating Permit Program), and 72 (Permits
                 Regulation, Acid Rain);
         201.2   Requirements contained in the California State
                 Implementation Plan (SIP), that are applicable to
                 the District; and
         201.3   District permit requirements established pursuant
                 to 40 CFR Part 52.21 (PSD) or District permit
                 requirements established pursuant to 40 CFR Part
                 51, Subpart I (NSR) and approved by U.S. EPA into
                 the SIP.
    
    202  FUGITIVE EMISSIONS:  Emissions which could not reasonably
         pass through a stack, chimney, vent, or other 
         functionally-equivalent opening.

    203  HAZARDOUS AIR POLLUTANT (HAP):  Any air pollutant listed
         pursuant to Section 112(b)  (42  U.S.C. Section 7412(b) of
         the Federal Clean Air Act.


    204  MAJOR STATIONARY SOURCE OF HAZARDOUS AIR POLLUTANTS (HAPs): 
         A stationary source that emits or has the potential to emit
         quantities equal to or exceeding the lesser of the
         following thresholds:
         204.1   10 tons per calendar year or more of a single HAP
                 listed in Section 112(b) of the Federal Clean Air
                 Act;
         204.2   25 tons per calendar year or more of any
                 combination of HAPs; or
         204.3   Any such lesser quantity as the U.S. EPA may
                 establish by rule.

         Fugitive emissions of HAPs shall be considered in
         calculating emissions for stationary sources.  The
         definition of a major stationary source of radionuclides
         shall be specified by rule by the U.S. EPA.

    205  MAJOR STATIONARY SOURCE OF REGULATED AIR POLLUTANTS:  A
         stationary source that emits or has the potential to emit
         a regulated air pollutant in quantities equal to or
         exceeding the lesser or any of the following thresholds:
         205.1   100 tons per calendar year of any regulated air
                 pollutant; and
         205.2   25 tons per calendar year of volatile organic
                 compounds or oxides of nitrogen.

         Fugitive emissions of these pollutants shall be considered
         in calculating total emissions  for stationary sources in
         accordance with 40 CFR Part 70.2.

    206  MAJOR STATIONARY SOURCE THRESHOLD:  The potential to emit
         a regulated air pollutant in the amounts specified under
         Sections 204 and 205.

    207  MODIFICATION:  Any physical or operational change at a
         stationary source or facility which necessitates a revision
         of any federally enforceable condition, established
         pursuant to this rule or by any other mechanism, that
         enables a source to be a synthetic minor source.

    208  OPERATING SCENARIO:  An operating scenario is any permitted
         mode of operation, including normal operation, startup,
         shutdown, and reasonably foreseeable changes in process,
         feed, or product.

    209  OWNER OR OPERATOR:  Any person who owns, leases, operates,
         controls, or supervises a stationary source.

    210  POTENTIAL TO EMIT:  The maximum physical and operational
         design capacity to emit a pollutant during each calendar
         year.  Limitations on the physical or operational design
         capacity, including emissions control devices and
         limitations on hours of operation, may be considered only
         if such limitations are federally enforceable.

    211  REGULATED AIR POLLUTANT:  Any of the following air
         pollutants are regulated:
         211.1   Oxides of nitrogen and volatile organic compounds;
         211.2   Any pollutant for which a national ambient air
                 quality standard has been promulgated under Title I
                 of the Federal Clean Air Act;
         211.3   Any pollutant that is regulated under any standard
                 promulgated under Section 111 (42 U.S.C. Section
                 7411) of the Federal Clean Air Act, including New
                 Source Performance Standards in 40 CFR Part 60;
         211.4   Any Class I or II substance subject to a standard
                 promulgated under or established by Title VI of the
                 Federal Clean Air Act;
         211.5   Any pollutant that is subject to any standard
                 promulgated pursuant to Sections 112 (42 U.S.C.
                 Section 7412) of the Federal Clean Air Act,
                 including:
            a.   Any pollutant listed pursuant to Section 112(r)
                 (Prevention of Accidental Release) shall be
                 considered a regulated air pollutant upon
                 promulgation of the list;
            b.   Any HAP subject to a standard or other
                 requirement promulgated by the U.S. EPA pursuant
                 to Sections 112(d) or adopted by the District
                 pursuant to Sections 112(g) and (j) shall be
                 considered a regulated air pollutant for all
                 sources or categories of sources:
              1. Upon promulgation of the standard or
                 requirement; or
              2. 18 months after the standard or requirement
                 was scheduled to be promulgated pursuant to
                 Section 112(e)(3); and
            c.   Any HAP subject to a District case-by-case
                 emissions limitation determination for a new or
                 modified source, prior to the U.S. EPA
                 promulgation or scheduled promulgation of an
                 emissions limitation shall be considered a
                 regulated air pollutant when the determination is
                 made pursuant to Section 112(g)(2) of the Federal
                 Clean Air Act.  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.

                 whether the request for synthetic minor source
                 status is complete not later than 30 days after
                 receipt of the request, or after such longer time
                 as both the owner or operator of the stationary
                 source and the Air Pollution Control Officer have
                 agreed in writing.  If the Air Pollution Control
                 Officer determines that the request is not
                 complete, the owner or operator shall be notified
                 in writing of the decision specifying the
                 information required.  Upon receipt of any 
                 re-submittal of the request, a new 30-day period to
                 determine completeness shall begin.  Completeness

                 enforceable permit conditions, including any
                 operational limitations or conditions, which limit
                 the source's potential to emit to below major
                 source thresholds;       
         403.3   Subject to public notice and U.S. EPA review
                 pursuant to Sections 404 and 405.

         the requirements of this Section, any other requirements of
         this rule, or any underlying federal regulations which set
         forth criteria for federal-enforceability may be deemed not
         federally enforceable by U.S. EPA.

                 this rule, and
            b.   Describe how the public may obtain copies of the

                 action to issue the Permit to Operate pursuant to
                 this section, a stationary source requesting
                 synthetic minor source status shall not be relieved
                 from the responsibility to comply with the
                 application or other requirements of District Rule

                 public and U.S. EPA review and take final action on
                 the Permit to Operate of a source requesting
                 synthetic minor source status within 90 days of
                 deeming such request complete.
         406.3   The District shall maintain a public record of all
                 pertinent documents regarding a request for

         synthetic minor source status shall be made in accordance
         with District Rule 201, GENERAL PERMIT REQUIREMENTS.  In
         addition, at permit renewal, any revision of conditions
         identified as federally enforceable shall be subject to the
         requirements of Sections 301 and 401 through 406 of this
         rule.
