100  APPLICABILITY



     101  General Applicability



          This rule applies to any major source for which the owner

          or operator requests, and would be able to comply with,

          federally-enforceable conditions that qualify the source

          to be a synthetic minor source, as defined in this rule.



     102  Exclusion



          This rule shall not apply to any source subject to Rule

          507, FEDERAL OPERATING PERMIT PROGRAM for any reason

          other than being a major source.



200  DEFINITIONS



     All terms shall retain the definitions provided under Rule

     507, FEDERAL OPERATING PERMIT PROGRAM, unless otherwise

     defined herein.



     201  Major Source Threshold: A major source threshold is the

          potential to emit a regulated air pollutant in the

          amounts specified in the definition of "major source" as

          defined in Rule 507, FEDERAL OPERATING PERMIT PROGRAM.



     202  Modification: For the purposes of this rule, a

          modification is any physical or operational change at a

          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.



     203  Operating Scenario: An operating scenario is any mode of

          operation to be permitted, including: normal operation,

          start-up, shutdown, and reasonably foreseeable changes in

          process, feed, or product.



     204  Owner or Operator: For the purposes of this rule, an

          owner or operator is any person who owns, operates,

          controls, or supervises a stationary source.



     205  Synthetic Minor Source: A synthetic minor source is a

          stationary source which, pursuant to this rule or another

          mechanism, is subject to federally-enforceable conditions

          that limit its potential to emit to below major source

          thresholds.  In addition, a synthetic minor source is

          subject to all applicable State and District rules,

          regulations, and other requirements.



300  ADMINISTRATIVE REQUIREMENTS



     A request for synthetic minor source status shall not relieve

     a source of the responsibility to comply with the application

     requirements of Rule 507, FEDERAL OPERATING PERMIT PROGRAM

     within the specified timeframes. A major source subject to

     this rule may request synthetic minor source status in

     accordance with the following:



     301  Content of Request



          A request for designation as a synthetic minor source

          shall include:



          301.1          The identification and description of all

                         existing emission units at the source;          

                         

          301.2          The calculation of each emission unit's

                         maximum annual and maximum monthly

                         emissions of regulated air pollutants for

                         all operating scenarios to be permitted,

                         including any existing federally-enforceable 

                         limits established by a mechanism other than 

                         this rule;



          301.3          Proposed federally-enforceable conditions

                         which:



                    a.   Limit source-wide emissions to below

                         major source thresholds, and



                    b.   Are permanent, quantifiable, and

                         otherwise enforceable as a practical

                         matter;



          301.4          Proposed federally-enforceable conditions

     303  Synthetic Minor Source Modification Requirements



          The following requirements apply to any modification of

          a synthetic minor source:



          303.1     For a modification which would not increase

                    the synthetic minor source's potential to emit

                    to equal or exceed any major source threshold,

                    the source shall comply with the requirements

                    of Rule 502, NEW SOURCE REVIEW.



          303.2     For a modification which would increase the

                    synthetic minor source's potential to emit to

                    equal or exceed any major source threshold or

                    would affect a monitoring, recordkeeping, or

                    reporting requirement pursuant to section

400  DISTRICT PROCEDURES AND FEDERALLY-ENFORCEABLE CONDITIONS



     The District shall take the following actions on requests for

     synthetic minor source status.



     401  Completeness Determination



          The APCO shall determine if the request for synthetic

          minor source status is complete within 30 days of

          receipt, unless a longer period of time is agreed upon by

          the APCO and the source's owner or operator.



          Thirty-one days after the request has been submitted, it

          may not be considered deemed complete unless the APCO so

          notifies the owner or operator.



     Upon request by the APCO, the owner or operator shall provide

     additional information whether or not the request for

     synthetic minor source status has been deemed complete.



     402  Federally-Enforceable Conditions



          Federally-enforceable conditions enabling a source to

          become a synthetic minor source shall be identified as

          federally-enforceable and included in the source's

          permit-to-operate issued by the District pursuant to Rule

          501, GENERAL PERMIT REQUIREMENTS Sections 403 through 405

          of this rule, and shall be:



          402.1     Permanent, quantifiable, and practically

                    enforceable permit conditions, including any

                    operational limitations or conditions, which

                    limit the source's potential to emit to below

                    major source thresholds;



          402.2     Monitoring, recordkeeping, and reporting

                    conditions sufficient to determine ongoing

                    compliance with the emissions limits set forth

                    pursuant to section 402.1 of this rule; and



          402.3     Subject to public notice and U.S. EPA review

          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 the U.S. EPA.



     403  Public Notification and Review



          After a request for synthetic minor source status is

          determined to be complete, the APCO shall:



          403.1     Publish a notice of the request in one or more

                    major newspapers in the area where the source

                    is located;



          403.2     In the public notice:



               a.   State that conditions identified as federally-enforceable in the source's permit will

                    establish a voluntary emissions limit in

                    accordance with Rule 512, REQUEST FOR

                    SYNTHETIC MINOR SOURCE STATUS; and

405  Final Action



          Until the District takes final action to issue the

          permit-to-operate pursuant to this section, a source

          requesting synthetic minor source status shall not be

          relieved of the responsibility to comply with the

          application or other requirements of Rule 507, FEDERAL

          OPERATING PERMIT PROGRAM, within the specified

          timeframes. Upon fulfilling the requirements of Sections

          401 through 404 of this rule, the APCO shall consider any

          written comments received during 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 after closure of both the public and U.S. EPA

          review process or within three years of the effective

          date of Rule 507, FEDERAL OPERATING PERMIT PROGRAM,

          whichever is later.



          The District shall maintain a public record of all

          pertinent documents regarding a request for synthetic

          minor source status, including: the request, proposed

          permit, all written comments and responses, and the final

          permit.



     406  Renewal of Synthetic Minor Source Status



          Renewal of synthetic minor source status shall be made in

          accordance with Rule 501, GENERAL PERMIT REQUIREMENTS. 

          In addition, at permit renewal, any revision of

          conditions identified as federally-enforceable shall be

          subject to Sections 301 and 401 through 405 of this rule.



500  COMPLIANCE



     The owner or operator of a synthetic minor source which

     exceeds the conditions identified as federally-enforceable and

     established pursuant to section 402.1 of this rule shall

     report such exceedances to the APCO in accordance with Rule

     404, UPSET CONDITIONS, BREAKDOWN OR SCHEDULED MAINTENANCE.



     The owner or operator of a synthetic minor source that is not

     in compliance with any condition identified as federally-

     enforceable or with any requirement set forth in this rule, or

     that files false information with the District to obtain

     synthetic minor source designation, is in violation of the

     Federal Clean Air Act and District rules and regulations.  A

     noncomplying synthetic minor source may be subject to any one

     or combination of the following actions: enforcement action,

     permit termination, permit revocation and reissuance, and

     permit renewal denial.
