  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.

     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 1S77 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), 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
                                  in

-------
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.

           except for motor vehicles  and  implements  of  husbandry, dust or condensed
           fumes of a weight in excess of the amount shown for the corresponding
           process weight  per  hour in  the following  table:

           To use the following table, take the process weight per hour as such is
           defined in Rule 1.2(w). Then  find this figure on the table, opposite
           which is the  maximum number of pounds of  contaminants which may be
           discharged Into the atmosphere in  any one hour.  As an ejxample, if A
           has a process which emits  contaminants Into  the atmosphere and which
           process takes 3 hours to complete, he will divide the weight of all
           materials in  the specific  process, in this example, 1,400 Ibs. by 3
           giving a process weight per hour  of 500  Ibs.  The table shows that A may
           not discharge more  than 1.77 Ibs.  in any  one hour during the process.
           Where the process weight per hour  falls between figures in the left hand
           column, the exact weight of permitted discharge may be Interpolated.
