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 T, "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 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), 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
                                   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.  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.

         exceeding in concentration  at the point  of discharge:

         A.   Sulphur compounds calculated as sulphur dioxide-0.2  percent, by
             volume.

         B.   Combustion contaminants - 0.3 grain  per cubic foot of gas calculated
             to 12 percent of carbon dioxide at standard  conditions.   In  measuring
             the combustion contaminants from incinerators used to dispose of
             combustible refuse by burning,  the carbon  dioxide produced by com-
             bustion of any liquid or gaseous fumes shall  be excluded from the
             calculation to 12 percent of carbon  dioxide.

         C.   Fluorine compounds - emissions shall  not exceed 2.5.  milligrams per
             cubic meter gas at standard conditions.

         D.   Sulfides - after December 31, 1973 no  person shall discharge total
             reduced sulfur from any recovery boiler in excess  of 60.0 ppm.
                                             -21-

-------
              After December 31,1973 no person  shall  discharge  total  reduced  sulfur
              from any other source in  excess of one  pound  per  ton  of dry wood
              charged.

         E.    Oxides of nitrogen  -  no person shall  discharge  oxide  of nitrogen  in
              excess of 140 pounds  per  hour for new or expanded installations,
              calculated as nitrogen dioxide  (N02).

(50.1.3)  RULE 4.6      Dust and Fumes

         A person shall  not discharge in any one hour from  any  source whatsoever,
         dust or fumes in total  quantities  in excess  of the amount  shown in the
         following table:  To use the following  table, take the process weight  per
         hour, as such is defined in Rule 1.2  (R).  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
         example, 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, 1500 IDS. x 3,
         giving a process weight  per hour of 500 IDS.  The  table shows that (A)
         may not discharge more than  1.771bs. 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 shall  be interpolated.

         A.    If air contaminants  from  two or more source operations  are combined               j
              prior to emission and there  are adequate and  reliable means reason-
              ably susceptible to  confirmation and use by the control officer  for
              establishing a separation of the components of  the  combined emission              i
              to indicate the  nature, extent» quantity and  degree of  emission
              arising from each such source operation, this regulation  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  emisions  cannot be  separated
              according  to the requirements of Rule  4.10 (a), this regulation
              shall be applied to  the combined emission as  if it  originated in

         or more emission points,  the total emitted  quantity  of any air contaminant,
         limited in this regulation cannot exceed  the  quantity which  would be  the
         allowable emission though a single emission point; and the total emitted
         quantity of any such  air  contaminant shall  be taken  as the product of
         the highest concentration measured  in any of  the emission points and  the
         exhaust gas volume through the source operation establishes  the correct
         total emitted quantity.

(51.21)  RULE 4.12    Reduction of Animal Matter

         A person shall  not operate or  use any equipment for  the  reduction of  animal
         matter unless all gases,  vapors and  gas-entrained  effluents  from such
         equipment are:

         carbonaceous material.

(50.1.2)  RULE 4.14     Uncombined Water

         When the presence of uncombined  water is the only  reason for  the  failure
         of  an emission to meet  the limitation of the visible emissions limitation
         (Section 24242), that rule shall not apply.   The burden of proof  which
         established the application of this exception shall  be upon the person
         seeking to come within  its provisions.

(51.13)                                   FOR
                              AGRICULTURAL  BURNING
                                          -32-

-------
(2.0)      INTRODUCTION
          Burning has been a tool  used  in agriculture  for many years.   It has been
          used to control weeds and pests and  dispose  of waste material.  Alterna-
          tives  have been developed in  some  instances  but additional research is
          needed to develop techniques  that  may completely eliminate the need for
          open burning.

          This plan was developed  with  the understanding that alternatives to open
          burning will be used in  all possible cases,  and that burning  will  be  used
          only as a last resort.   Without the  development and utilization of alter-
          natives,, this plan will  not reduce the quantity of air contaminants dis-
          charged into the atmosphere,  but will only aide in the dispersion  and
          dilution of them.
(2.0)     GENERAL
          In accordance with  Section  39298.8 of the  California  Health and  Safety                |
          Code, each  district in  the  State  shall  adopt  an  implementation plan                   j
          consistent  with the Agricultural  Burning Guidelines.   Local authorities,
          within each basin,  may  jointly adopt an implementation plan for  their
          combined areas.                                                                       !

          The plan shall be adopted by  regulation and any  violation  of  the provisions
          of the plan is a misdemeanor  punishable by imprisonment in the county                 !
          jail not exceeding  six  (6)  months, or by a fine  not exceeding five-
          hundred ($5000.), or both,  and the cost of extinguishing the  fire. Every
          day during  any portion  of which such offense  occurs constitutes  a separate
          offense.

          The fire control agency designated by the  Board  and having jurisdiction
          over the site of the burn and the air pollution  control  district shall
          enforce these Rules and Regulations.

         B.    A permit shall not be issued to an applicant unless information
              provided as required by the designated fire protection agency for
              fire protection  purposes.

         C.    A permit shall not be issued to an applicant unless information is
              provided as required by the District.

         D.    All  material  to  be burned shall  be reasonably free of dirt,  soil,
              and excess moisture.

         E.    Wherever possible, wastes shall  be piled or windrowed in such a
              manner as to burn  with maximum possible heat density and minimum
              smoke.

         F.    All  burning shall  be ignited as rapidly as practicable within appli-
              cable fire control restrictions.

         G.    All  wastes shall be free of tires, tar paper, construction debris,
              or other types of  rubbish likely to cause excessive smoke or obnoxious
              odors.

         H.    Special  consideration shall be given to burning operations confined
              to narrow inland river valleys where smoke containment may be re-
              stricted within  the river basin and greatly decrease the prevailing
              visibility.

         I.    All  materials  to be burned shall  be ignited with an approved ig-
              nition device.

         J.    A permit shall not be valid for any day in which burning is  pro-
              hibited by the designated fire control agency having jurisdiction
              over the site  of the burn for the purposes of fire control or pre-
              vention.

         K.    A permit shall be  valid for only those days which agricultural  burn-
              ing is not prohibited by the Board or the District.

         L.    Open outdoor fires must be controlled to such an extent as is techni-
              cally and economically feasible to meet all Federal and State air
              quality standards  pertaining to air pollutants created by open
              burning operations.

     ent to cause State ambient air quality standards to be exceeded.
0.   Maximum care must be taken to keep smoke form drifting into pop-
     ulated areas.
P.   Permittee should not burn when winds exceed 20 miles per hour or
     when weather conditions are unsafe to burn.

PROHIBITIONS  I.  Range Improvement Burning

A.   Between January 1 and May 31, range improvement burning may be
     conducted by permit on a NO-BURN DAY, providing that more than
     5 acres of the land has been brush treated.

     Notwithstanding the provisions in Subdivision A of this section,
     the Board may prohibit range improvement burning during the period
     designated by the district if in the opinion of the Board* such
     prohibition is required for the maintenance of suitable air quality.

B.   If the burning is to be done primarily for improvement of land for
     wildlife and game habitat, no permit shall be issued unless the
     applicant has filed with the District a statement from the Depart-
     ment of Fish and Game, certifying that the burn is desirable and
     proper.

C.   The brush shall be treated if economically and technically feasible
     prior to the burn.

(3.0)     BURNING  PERMITS  - General

         The  public  has been accustomed to obtaining burning permits from the
         various  fire  protection agencies.  There are stations strategically
         located  in  most  areas, and  it would be logical to designate these
         agencies as the  person to issue the permits for agricultural burning.
         These agencies would also be in the position to coordinate air quality
         control  criteria as well as fire protection criteria that would relate
         to the agricultural burning.

         A.   The burning permit shall be prepared in sufficient copies to pro-
             vide information to the various agencies of concern.  The permitted
             shall  have  his copy available for inspection at the burn site.
             This procedure will minimize any charges of burning without a
             valid  permit.

         B.   In  order to provide for proper control of the agricultural burning,
             a separate  permit shall be obtained for each burning operation as
             well as  for each different burn site.  A burning operation may ex-
             tend over several days, but it must be the same type of material
             and on the  same burn site.

         C.   The permit  shall be issued for the length of time necessary to
             complete the burning operation.  The permittee shall contact the
             local  fire  protection  agency prior to each day's burn to determine
             if  it  is an authorized burn day as well as informing them that a
             burn is  about to take  place.

         D.   The application for a  burning permit shall be reviewed by the
             issuing  agency.  If the bum is likely to cause a nuisnace, or the
             request  is  not consistent with agricultural burning, the permit
             shall  not be issued until approval is obtained from the Air Pollu-
             tions  Control District.  A nuisance might be caused if the location
             of  the burn site and the direction of the prevailing winds will
             direct the  air contaminants toward an adjacent residential area.

         E.   Each permit issued pursuant to these procedures shall bear a state-
             ment of  warning containing the following words or words of like or
             similar  import:

             "This  permit is valid  only on those days which agricultural
             burning  is  not prohibited by the California Air Resources Board
             pursuant to Section 29298 or the local air pollution control
             district."

         F.   All burning permits will be issued by the designated fire control
             agency having jurisdiction in the area of the proposed burn and
             shall  state thereon the type of material to be burned, estimated
             tonnage  or  acreage of waste to be burned, and the classification
             of burning  under which the permit was issued.
                                             -44-

(13.0)    AGRICULTURAL BURNING REPORTS

         Either of the following methods may be used for the report.

         1.   The permittee shall be required to call the designating agency
              issuing the permit prior to each burn.  The designated agency shall
              log the information required on the form provided by the Air Pollu-
              tions Control District at the end of each month.

         2.   Reporting cards shall be provided by the Air Pollution Control
              District to the designating agency for distribution.  The permittee
              shall complete a reporting card for the material burned each day
              and mail the card within 28 hours.

         3.   Persons requesting advance notification for a specific range im-
              provement burn or of a specific forest management burn above 3,000
             j feet shall submit to the California Air Resources Board a notifi-
             •v cation request card which may be obtained at the designated
              agencies.
                                             -45-
