                             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 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), 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
                                      111

-------
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.

                                        REGULATION  I.

(2.0)     RULE 1.     TITLE

         Pursuant to the provisions  of Chapter 2, Division 20 of the Health and
         Safety Code of the  State  of California, the Air Pollution Board of the
         County of the  Trinity Air Pollution Control District does hereby enact
         the following  rules and regulations to be  known as the "RULES AND REGU-
         LATIONS OF THE TRINITY  COUNTY AIR  POLLUTION CONTROL DISTRICT."

(1.0)     RULE 2.     DEFINITIONS.

                                     EPISODE PROCEDURES


         This regulation is designed to prevent the excessive buildup of air
         contaminants during air pollution episodes and to avoid any possibility
         of a catastrophe caused by toxic concentrations of air contaminants.
         Past history indicates  that the possibility of such a catastrophe is
         extremely remote.

         The Air Pollution Control  Board deems it  desirable to have ready an
         adequate plan to prevent such an occurrence,  and in case of the happening
         of this unforeseen event,  to provide for adequate actions to protect  the

         ALERT - The "Alert" level is  that concentration of air  pollutants  at
         which first stage control actions are to  begin.   An "Alert"  will be
         declared when any one of the  above  levels is exceeded and meteorological
         conditions are such that this condition can be  expected to continue  for
         twelve (12) or more hours.

         WARNING - The "Warning" level indicates that air quality is  continuing
         to degrade and that additional  abatement  actions are necessary.

         EMERGENCY - An "Emergency" level will be  declared when  the "Warning  level
         for a pollutant has been exceeded and the concentrations of  the  pollutant
         are continuing to increase.

         TERMINATION - Any status reached by application of the  above criteria
         will  remain in effect until the criteria  for that level  are  no  longer met.
         At such time the next lower status  will be  assumed.
