  This document has  been produced in compliance with Section 110(h)(l)  of the Clean Air
  Act amendments of  1977.   The Federally enforceable regulations contained in the State
  Implementation Plans  (SIPs) have been compiled for all 56 States  and  territories
  (with the exception of the Northern Mariana  Islands).  They consist of both the
  Federally approved State and/or local air  quality regulations as  indicated in the
  Federal Register and  the Federally promulgated regulations for the State, as
  indicated in the Federal Register. Regulations which fall into one of the above
  categories as of January 1,1978, have been  incorporated.  As mandated by Congress,
  this document will be updated annually.  State and/or local air quality regulations
  which have not been Federally approved as  of January 1, 1978, are not included here;
  omission of these  regulations from this document in no way affects the ability of
  the respective Federal,  State, or local agencies to enforce such  regulations.

                             INTRODUCTION


     This document has been produced in compliance with Section 110(h)(l)
of'the Clean Air Act Amendments of 1977.  The Federally enforceable
regulations contained in the State Implementation Plans (SIPs)  have been
compiled for all 56 States and territories (with the exception  of the
Northern Mariana Islands).  They consist of both the Federally  approved
State and/or local air quality regulations as indicated in the  Federal
Register and the Federally promulgated regulations for the State, as
indicated in the Federal Register.  Regulations which fall into one of
the above categories as of January 1, 1978, have been incorporated.  As
mandated by Congress, this document will be updated annually.   State
and/or local air quality regulations which have not been Federally
approved as of January 1, 1978, are not included here; omission of these
regulations from this document in no way affects the ability of the
respective Federal, State, or local agencies to enforce such regulations.
                      i
     There have been recent changes in the Federal enforceabi1ity of
parking management regulations and indirect source regulations.  The
October, 1977, appropriation bill for EPA prohibited Federal enforcement
of parking management regulations in the absence of specific Federal
authorizing legislation.  Federally promulgated parking management
regulations have, therefore, been suspended indefinitely.  Pursuant to
the 1977 Clean Air Act Amendments, indirect source regulations  may not
be required for the approval of a given SIP.  Consequently, any State
adopted indirect source regulations ipay be suspended or revoked; State
adopted indirect source regulations contained in an applicable  SIP
are Federally enforceable.  More importantly, EPA may only promulgate
indirect source review regulations which are specific to Federally
funded, operated, or owned facilities or projects.  Therefore,  the
Federally promulgated indirect source regulations appearing in  this
document are not enforceable by EPA except as they relate to Federal
facilities.

     Since State air quality regulations vary widely in their organization,
content, and language, a standardized subject index is utilized in this
document.  Index listings consist of both contaminant and activity oriented
categories to facilitate usage.  For example, for regulations which apply
to copper smelters, one might look under sulfur compounds (50.2), particu-
late matter process weight (50.1.1), or copper smelters (51.15).  Federal
regulations pertaining to a given State immediately follow the  approved
State and local regulations.

     Additionally, a summary sheet of the information included  in each
comprehensive document is presented prior to the regulatory text to
allow one to quickly assess the contents of the document.  Specifically,
the summary sheets contain the date of submittal to EPA of each revision
                                       iii

-------
to the SIP and the date of the Federal Register in which the revision
was either approved or disapproved by EPA.  Finally, a brief description
or reference of the regulation which was submitted is also included.

     This document is not intended to provide a tool for determining
the enforceability of any given regulation.  As stated above, it is
intended to provide a comprehensive compilation of those regulations
which are incorporated directly or by reference into Title 40, Part 52,
of the Code of Federal Regulations.  Consequently, the exclusion of a
Federally approved regulation from this document does not diminish the
enforceability of the regulation.  Similarly, the inclusion of a given
regulation (for example, regulations governing pollutants, such as odors,
for which there is no national ambient air quality standards) in this
document does not, in itself, render the regulation enforceable.

(2.0)     Rule 405    Separation  of  Emissions.

         If air contaminants  from a single  source  operation are emitted through
         two or more  emission points,  the total  emitted quantity of air contam-
         inants cannot exceed the quantity  which would be allowable through a
         single emission point.

         The total emitted quantity of any  such  contaminant shall  be  taken as  the
         product of the highest concentration measured  in any of  the  emission   points
         and the combined exhaust  gas  volume through all emission  points,  unless
         the person responsible for the source operation establishes, to the Air
         Pollution Control Officer's satisfaction, the  correct total  emitted
         quantity.

(2.0)     Rule 406    Combination of Emissions.

         A.  If air contaminants from  two or more  source operations are combined
             prior to emission and   there are adequate  and reliable means  rea-
             sonably  susceptible for confirmation  and use by  the Air  Pollution
             Control  District in establishing a  separation of the  components of
             the combined emission  to  indicate the nature, extent, quantity and
             degree of emission  arising from each  such  source operation, the
             Rules and Regulations  shall apply to  each  such source operation
             separately.

         B.  If air contaminants from  two or more  source operations are combined
             prior to emission and  the combined  emissions cannot  be separated
             according to the requirements  of Rule 406  (A|, the Rules and  Reg-
             ulations shall  be applied to the combined  emissions  as if it
             originated in a single source  operation subject  to the most stringent
             limitations and requirements placed by the Rules and  Regulations  on
             any of the source operations whose  air contaminants  are  so combined.

(2.0)     Rule 407    Circumvention.

         A person shall not build,  erect, install, or use any article, machine,
         equipment or other contrivance, the use of which, without resulting in
         an actual reduction in  the total release  of air contaminants to the
         atmosphere,  superficially  reduces  or conceals  an emission which would
         otherwise constitute a violation of Division 20, Chapter  2,  of the
         Health and Safety Code of  the State of  California or of  these Rules and
         Regulations.  This Rule shall not  apply to cases in  which the only
         violation involved is of Section 24243  of the  Health and  Safety Code,
         or of Rule 205 of these Rules and  Regulations.

(13.0)   Rule 408    Source Recordkeeping and Reporting.

         The owner or operator of any  stationary source, shall, upon  notification
         from the District,  maintain records of  the nature and amounts of  emis-
         sions from such source  and/or any  other information  as may be deemed
         necessary by the District  to  determine  whether such  source is in  com-
         pliance with applicable emission limitations or other control measures.

         The Air Pollution Control  Officer may  require  that  such  records be
         certified by a professional  engineer registered  in  the State  of
         California.   Such studies  shall  be at  expense  of the  person causing
         the emissions.

         The information recorded shall be summarized and reported to  the
         District, on forms or formats as furnished  by  the District, and shall
         be submitted within 45 days  after the  end of the reporting period.
         Reporting periods are January 1  - June 30 and  July  1  - December 31,
         except that  the initial reporting period shall commence  on the date
         the District issues notification of the recordkeeping requirements.

         Information  reported by the  owner or operator  and copies of the
         summarizing  reports submitted to the District  shall be retained by the
         owner or operator for two  years  after  the date on which  the pertinent

             other .pollution which  any article,  machine,  equipment or  other
             contrivance will  produce which the District  requires any  applicant
             to provide before such applicant builds, erects, alters,  replaces,
             operates,  sells,  rents,  or uses such article, machine, equipment
             or other contrivance,  are public records.

         B.   All  air  or other pollution monitoring data,  including data compiled
             from stationary sources, are public records.

         C.   Except as  otherwise provided in (D), trade secrets   are not public
             records  under this  Regulation.   Trade secrets,  as used in this

             known only to certain  individuals within a commerical concern who
             are  using  it to fabricate, produce, or  compound an article of trade
             or a service having commercial  value and which  gives its  user an
             .opportunity  to obtain  a  business advantage over competitors who
             do not know  or use  it.

         D.   Notwithstanding any other provisions of the  law, all  air  pollution
             emission data,  including those emission data  which constitute trade
             secrets  as  defined' in  (C), are public records.  Data used to cal-
             culate emission data are not emission data for  purposes of this
             subsection  and data which constitute trade secrets and which are
             used to  calculate emission data  are not public  records.

         E.   Request  for  trade secrets status shall  be  made  by written applica-
             tion to  the  Air Pollution Control Officer.   The claimant  shall de-
             clare and  justify in writing  information he  desires  to be classi-
             fied as  trade  secrets.  The  Air Pollution  Control Officer shall
             determine whether the  information submitted  is  to be classified as
             trade secrets  subject  to the  conditions of this rule.
