  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

                                                               k
     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 19 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.

     There have been recent changes in the Federal enforceability  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 may 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)s 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
                                                  NOT REPRODUCIBLE
                                   m

-------
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. «fts stated above, it is
intended to provide a comprehensive compilation of those regulations
which ara 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.

         against  him.   If respondent  does not testify in  his own behalf he
         may be called and examined as  if under cross-examination.

              c.   The  hearing need not  be conducted according  to technical  rules
         relating to evidence and  witnesses.  Any  relevant evidence  shall be
         admitted if it  is the  sort of  evidence on which  responsible persons are
         accustomed  to  rely in  the conduct of serious affairs  regardless of the
         existence of  any common law  or statutory  rule which might make improper
         the admission  of such  evidence over objection in civil actions.
         Hearsay  evidence may be used for the purpose of  supplementing or
         explaining  any  direct  evidence but  shall  not be  sufficient  in itself
         to support  a  finding unless  it would be admissible  over objection  in
         civil actions.   The rules of privilege shall be  effective to the
         same extent that they  are now  or hereafter may be  recognized in civil
         actions, and  irrelevant and  unduly  repetitious evidence shall be
         excluded.

(2.0)         RULE 106.   Record of Proceedings.

              A record  of all proceedings had before  the  Hearing Board shall
         be made. The  record shall  be  prepared in accordance  with one of  the
         following methods:  1-A written summary of  all  the  evidence, testimony
         and proceedings had and presented at the  hearing shall  be made by a
         person designated by the Hearing Board for  that  purpose; or 2-Any
         interested  person, including the District,  may  at  his own cost provide
         a certified shorthand  reporter satisfactory  to  the  Hearing  Board  who
         shall prepare a verbatim transcript of all  the  evidence, testimony
         and proceedings had and presented at the  hearing.

              The original and  one copy of such transcript,  each certified to
         by the reporter as to  its accuracy, shall be filed with the Hearing
         Board within  30 days from the  closing  date  of the hearing  unless
         required by the Board  prior to that time.  No matter shall  be  deemed
         submitted under this regulation until  such transcript has  been  filed
         with the Hearing Board unless  otherwise ordered by the Hearing  Board.

(2.0)         RULE 107.   Preliminary Matters.

              Preliminary matters such  as setting  a date for hearing,  granting
         continuances,  approving petitions for  filing,  allowing amendments and
         other preliminary rulings are  determinative of the merits  of the
         case may be made by the chairman or any two members of the  Hearing
         Board without a hearing or meeting of  the Hearing Board and without

         of an air pollution episode  whenever  the concentration of an air
         contaminant which caused the declaration of such episode has been
         verified  to have fallen  below the standards set forth in Rule 156
         for the calling of  such  episode and the available scientific and
         meteorological data indicates that  the  concentration of such air
         contaminant will not immediately  increase again so as to reach the
         standards set forth for  such episode  in Rule 156.  The Air Pollution
         Control Officer shall immediately communicate the declaration of the
         termination of the  alert in  the manner  provided in Rule 155.1 for
         the delcaration of  episodes.
