                                RULE 522

                 REQUEST FOR SYNTHETIC MINOR SOURCE STATUS

522.1     GENERAL

     A.   PURPOSE:  This rule authorizes the owners or operators of
          specified stationary sources that otherwise be major
          sources to request and accept federally-enforceable
          emission limits sufficient to allow the source to be
          considered "synthetic minor sources".

          A synthetic minor source is not subject to Rule 500 TITLE
          V - FEDERAL OPERATING PERMIT PROGRAM, unless it is
          subject to that rule for any reason other than being a
          major source.  A synthetic minor 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 source is subject to all applicable State
          and District rules, regulations, and other requirements.

     B.   APPLICABILITY:  

          1.   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 sources,
               as defined herein.

          2.   This rule shall not apply to any source subject to
               Rule 500 TITLE V - FEDERAL OPERATING PERMIT
               PROGRAM, for any reason other than being a major
               source.

522.2     DEFINITIONS:  All terms shall retain the definitions
          provided under Rule 500 TITLE V - FEDERAL OPERATING
          PERMIT PROGRAM, unless otherwise defined herein.

     A.   MAJOR SOURCE THRESHOLD:  The potential to emit a
          regulated air pollutant in the amounts specified in the
          definition of a "major source" as defined in Rule 500
          TITLE V - FEDERAL OPERATING PERMIT PROGRAM.

     B.   MODIFICATION:  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.

     C.   OPERATING SCENARIO:  Any mode of operation to be
          permitted, including:  normal operation, start-up,
          shutdown, and reasonably foreseeable changes in process,
          feed, or product.  

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

     E.   SYNTHETIC MINOR SOURCE:  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.

522.3     STANDARDS

     A.   MODIFICATION REQUIREMENTS:  The following requirements
          apply to any modification of a synthetic minor source:

          1.   For a modification that 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 NEW SOURCE
               REVIEW.

          2.   For a modification that 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 522.4 D.3. of this
               rule, the owner or operator shall comply with the
               applicable requirements of NEW SOURCE REVIEW,  and
               shall:

               a.   Submit a revised request for synthetic minor
                    status in accordance with Section 522.4 A. of
                    this rule no later than 180 days prior to the
                    intended modification; or

               b.   Submit an application in accordance with the
                    requirements of Rule 500 TITLE V - FEDERAL
                    OPERATING PERMIT PROGRAM, no later than 180
                    days prior to the intended modification.

522.4     ADMINISTRATIVE REQUIREMENTS

     A.   REQUEST FOR SYNTHETIC MINOR STATUS:  

          1.   A request for synthetic minor source status shall
               not relieve a source of the responsibility to

               a.   The identification and description of all
                    existing emission units at the source;

               b.   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;

               c.   Proposed federally-enforceable conditions
                    which:
                    
                    1.   Limit source-wide emissions to below
                         major source thresholds, and;

                    the contents of the request are true,
                    accurate, and complete.

     B.   REQUEST SCHEDULE:  The owner or operator of a major
          source who chooses to request synthetic minor source
          status shall make such a request within the following
          timeframes:

          1.   For any major source that is operating or is
               scheduled to commence operating on the effective 
               date of Rule 500 TITLE V - FEDERAL OPERATING PERMIT
               PROGRAM, the owner or operator shall request
               synthetic minor source status no later than 60 days
               before an application is required under Rule 500
               TITLE V - FEDERAL OPERATING PERMIT PROGRAM.

          2.   For any major source that commences operating after
               the effective date of Rule 500 TITLE V - FEDERAL
               OPERATING PERMIT PROGRAM, the owner or operator
               shall request synthetic minor source status no
               later than 60 days before an application is
               required under Rule 500 TITLE V - FEDERAL OPERATING
               PERMIT PROGRAM.

          3.   For a major source that is operating in compliance
               with a permit pursuant to Rule TITLE V - FEDERAL
               OPERATING PERMIT PROGRAM, the owner or operator
               shall request synthetic minor source status at any
               time, but no later than 180 days prior to permit
               renewal.

     C.   COMPLETENESS DETERMINATION:  The Air Pollution Control
          Officer shall determine if the request for synthetic
          minor status is complete within 30 days of receipt,
          unless a longer period of time is agreed upon by the Air
          Pollution Control Officer and the source's owner or
          operator.

     D.   FEDERALLY-ENFORCEABLE CONDITIONS:  Federally-enforceable
          conditions enabling a source to become a synthetic minor
          source shall be identified as federally enforceable
          included in a source's Permit to Operate issued by the
          Air Pollution Control Officer in accordance with Rule 500
          GENERAL PERMIT REQUIREMENTS, and Sections 522.4 E., F.,
          and G. of this rule, and shall be:

          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;

          2.   Monitoring, recordkeeping, and reporting conditions
               sufficient to determine on-going compliance with
               the emission limits set forth pursuant to Section
               522.4 D.1. of this rule; and

          3.   Subject to public notice and U.S. EPA review
               pursuant to Sections 522.4 E. and 522.4 F. of this
               rule.

          Permits that do not conform to the requirements of this
          Section, and 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.

     E.   PUBLIC NOTIFICATION AND REVIEW:  After a request for
          synthetic minor status is determined to be complete, the
          Air Pollution Control Officer shall:

          1.   Public a notice of the request in one or more major
               newspapers in the area where the source is located;

          2.   In the public notice:

               a.   State that conditions for the source
                    identified as federally-enforceable in the
                    source's permit will establish a voluntary
                    emissions limit in accordance with this Rule
                    and

               b.   Describe how the public may obtain copies of
                    the proposed permit including the federally-
                    enforceable conditions addressing the
                    emissions limit; and

          3.   Provide 30 days for public review to final permit
               action.

     F.   U.S. EPA REVIEW:  After a request for synthetic minor
          source status is determined to be complete, the Air
          Pollution Control Officer shall:

          1.   Provide the U.S. EPA with copies of the proposed
               permit including the conditions which:

               a.   Are identified as federally-enforceable, and

               b.   Limit emissions to below major source
                    thresholds;

          2.   Provide 30 days for U.S. EPA review of the proposed
               permit prior to final permit action; and

          3.   Provide the U.S. EPA with copies of the final
               permit.

     G.   FINAL ACTION:

          1.   Until the Air Pollution Control Officer takes final
               action to issue the Permit to Operate pursuant to
               this Section, a source requesting synthetic minor
               status shall not be relieved of the responsibility 
               to comply with the application or other
               requirements of Rule 500 TITLE V - FEDERAL
               OPERATING PERMIT PROGRAM, within the specified
               timeframes.

          2.   Upon fulfilling the requirements of Sections 502.4
               C. through 522.4 F. of this rule, the Air Pollution
               Control Officer 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 of deeming such request complete or within
               three years of the effective date of Rule 500 TITLE
               V - FEDERAL OPERATING PERMIT PROGRAM, whichever is
               later.

          3.   The Air Pollution Control Officer 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. 

     H.   RENEWAL OF SYNTHETIC MINOR STATUS:  Renewal of synthetic
          minor source status shall be made in accordance with Rule
          500 GENERAL PERMIT REQUIREMENTS.  In addition, at permit
          renewal, any revision of conditions identified as
          federally enforceable shall be subject to the provisions
          of Sections 522.4 A. and 522.4 C. through 522.4 G. of
          this rule.

     I.   COMPLIANCE:    

          1.   The owner or operator of a synthetic minor source
               which exceeds the conditions identified as
               federally enforceable and established pursuant to
               Section 522.4 D.2. of the rule shall report such
               exceedances to the Air Pollution Control Officer in
               accordance with Rule 404 UPSET AND BREAKDOWN
               CONDITIONS.

          2.   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 file
               false information to the Air Pollution Control
               Officer to obtain synthetic minor source
               designation, is in violation of the Clean Air Act
               and District Rules and Regulations.  A non-
               complying synthetic minor source may be subject to
               the one or combination of the following actions: 
               enforcement action, permit termination, permit
               revocation and reissuance, and permit renewal
               denial.
