  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  •

                             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 or 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-
jlate 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 ars 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.

(50.1)    RULE 4.10     Particulate Matter

         Except as otherwise provided in Health  and Safety  Code  Section 24245
         and Rules 4.4 and 4.8,  a person shall not release  or discharge into
         the atmosphere from any source or single  processing  unit whatsoever,
         dust, fumes,  or particulate matter emissions  in  excess  of  0.3 grains
         per cubic foot of gas at standard conditions.

(50.1.1) RULE 4.11     Dust and Condensed Fumes

         A person shall not discharge in any one hour  from  any source whatsoever
         dust or fumes in total  quantities in excess of the amounts shown in  the
         following table:

         To use the following table, take the process  weight per hour as  such is
         defined in the attached definitions. 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 4 hours to complete, he will divide  the weight of  all
         materials in the specific process, in this example, he will divide the
         weight of all materials in the specific process, in this  example, 2,400
         IDS. by 4 giving a process weight per hour of 600  Ibs.   The table
         shows that A may not discharge more than 1.83 Ibs. in any one  hour during
         the process.   Interpolation of the data in the table for process weights
         up to 60,000 pounds/hour  shall  be accomplished by use of  the equation:

                                      E  = 4.10 P0.67

          and  interpolation and  extrapolation of the data for  process weight rates
          in excess of 60,000  pounds/hour shall be  accomplished by  use of the
          equation:

                                      E  = 55.0 P0-11 -  40   .

                              E  =  rate of emission  in pounds/hour.
                              P  =  process weight rate in  tons/hour.

         Division 26.

(2.0)    RULE 4.17     Circumvention                 1
                                                     i
         A person shall  not build,  erect,  install, or use any  article, machine,
         equipment or other contrivance, the  use of which,  without resulting  in
         a reduction in the total release  of  air contaminants  to the atmosphere,
         reduces or conceals an emission which would  otherwise constitute  a viola-
         tion  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 of the State of California.
                                             -18-

-------
         When the presence of uncombined water is  the  only  reason  for the failure
         of an emission to meet the limitation of  Prohibition  I, that rule shall
         not apply.   The burden of proof which establishes  the application of the
         rule shall  be upon the person seeking to  come within  its  provisions.

(2-0)    RULE 4.18     Separation of Emissions

         If air contaminants from a single source  operation are emitted  through
         two 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 through a single emission point; 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
         combined exhaust gas volume from all  emission points, unless the person
         responsible for the source operation  establishes,  to  the  satisfaction
         of the Air Pollution Control Officer, the correct  total emitted quantity.

(2.0)    RULE 4.19     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 reason-
              ably susceptible to confirmation and  use by the Air Pollution  Control
              Officer for.establishing a separation of the components  of the com-
              bined emission to indicate the nature, extent, quantity  and degree of
              emission arising from each such source operations, then  all of the
              applicable prohibitions shall apply to each such.source  operation
              separately.

         b.   If air contaminants from two or more  source ouerations are combined
              prior to emission, and  the combined emissions cannot be separated
              according to the requirements of Part a of the prohibition, then  all
              applicable prohibitions shall be applied to the combined  emission  as
              if  it originated  in a single source operation, subject to the most
              stringent  limitations and  requirements placed by these prohibitions
              on any of  the  source operations whose air contaminants are so
              combined.  Source operation means the last operation proceeding the
              emission of an air contaminant, which operation

         c.   Results in the separation of the air contaminants from the processed
              materials or in the conversion of the processed  materials into air
              contaminants, as in the case of the  combustion of fuel;  and

         d.   Is not an Air Pollution Abatement operation.

(12.0)   RULE 4.20     Emission Control for Used Motor Vehicles

         Each 1955 through 1962 model year used car in the District shall  be
         required to be equipped with an approved  crankcase emission control
         device at the time of transfer of ownership.

(51.13)   RULE 6.5      Restricted Burning Days

         If for any reason  it becomes likely that wastes  from more  than 10%  of
         the total agricultural acreage within a  district will be burned on  any
         one day, the Control Officer shall notify the local agencies designated
         in Section 6 that  a condition  of restricted burning exists. On days
         of restricted burning local agencies shall  restrict the  acreage allo-
         cated to the agency.  The Control  Officer shall  pro-rate the amounts
         to be burned to each agency based on the estimated number  of acres  in

RULE 6.6A     Notification to Fire Department of "Burn Day"  or "No Burn
              Day" at 8:00 A.M.  each morning

I.   The below rules apply only to rice stubble burning, for farmers,
     from October 1 through November 15th.   All  other burninq will  bt
     handled as in the past.

     1.   The farmers must first acquire a Fire Permit from the district
          where "stubble burn" is to occur.

     2.   Prior to burning rice stubble, the fanner, must have authori-
          zation from the APO.

          A.  Will require Fire Permit #,

          B.  Acres to be burned that day, and

          C.  Other pertinent information, i.e.
              certain wind direction for safety etc.

     3.   If allotment for the day is complete the farmer's name will  be
          put on a list for the.next available "Burn Day".  But the farmer
          must phone the APO prior to 10:00 A.M. to confirm his inten-
          tions to burn on the day designated.

     4.   If a farmer has authorization to burn and some problem arises
          so he can't burn - notify the APO so his allotment can be
          given to another person.  Arrangements will be made for a future
          date with the person who returned his allotment.

II.  Fire Chief's Information

     1.   Information will be relayed to the respective Fire Chief's who
          is burning, how many acres and if there is an allotment left,
          by 12:00 noon.  If the farmer decides at the last minute he
          wishes to burn he may contact either the Fire Chief or the APO
          for authorization on that given day.  If acreage allotment is
          still available, he may burn stubble.

NOTE:     To alleviate a build up of rice stubble for these 45 days one
          should burn rice stubble when it is ready prior to October 1st.
                                     -27-

               ing with the testing method described in Section e of these
              ' provisions.
     ?.  After a rain

          (a)  After a rain exceeding .15 inch (fifteen hundredths of an
               inch), rice straw shall not be burned unless the straw
               makes an audible crackle when tested just prior to ....
               burning with the testing method described in .Section e.
               of these provisions.

e.   Testing Procedures to Determine Straw Dryness

         b.    The burning is performed with LPG  or natural  gas  - fire burners
              designed and used to kill  seeding  grass  and weeds in orchards and
              field crops, and the growth is such  that combustion  will not  continue
              without the burner, also when used in the harvesting of certain vine
              crop seeds for dessication purposes.

(51.13)   RULE 6.8       Tires

         The use  of tires for the ignition of fires is prohibited.

(51.13)   RULE 6.9       Fire Prevention

         Nothing  in these rules is intended to permit  open burning of agricultural
         waste on days designated by the California Air Resources  Board as  "no-
         burn days" because the denial  of such permit  would threaten  eminent as
         substantial economic loss.

(51.13)   RULE 6.10      Burning on No-Burn Days

         The APO  may by permit authorize burning of agricultural waste on days
         designated by the California Air Resources Board as  "no-burn days"

39067.2.

The motor vehicle is the major source of the atmospheric pollution in
California and costs the state untold millions of dollars annually.   It
has been often suggested that periodic inspection of the engine systems
of motor vehicles would be an incentive for their owners to properly
maintain the vehicle, thus achieving a measurable reduction in vehicle
emissions.  However, the benefits and costs associated with an emissions
inspection program are unknown.

Therefore, the board shall undertake a study project to determine (a)
the reduction in automotive emissions that could be achieved by practi-
cable vehicle emission inspection programs and (b) the costs of carrying
out such programs on a permanent basis.

The board shall report its findings and recommendations to the Legislature
no later than July 1, 1971.  Should the board recommend the initiation
of any specific vehicle emission inspection program, its report shall
describe in detail its estimate of the reduction in air pollution that
would be achieved, the manner in which the program would operate, and
its projected annual costs.  (Added by Stats. 1970. Ch. 451.)

39068.

All penalties paid to the board pursuant to subdivision (m) of Section
39052 shall be paid into the State Treasury for credit to the Air Pollu-
tion Control Fund, which fund is hereby created.  The inonev paid into
the Air Pollution Control Fund is continuously  appropriate  to the board
to carry out the provisions of this part.  (Amended by Stats. .1970, Ch.694)

39068.1.

(a)  During the 1972 model year, but not later than January 1, 1972,
     the regulations adopted pursuant to subdivision (m) of Section .39052
     shall provide for the testing of motor vehicles on factory assembly
     lines or in such manner as the board determines best suited to, carry
     out the purpose of this part.                                 >
                                                                   !
(b)  Should a motor vehicle not meet the prescribed assembly line stand-
     ards, the motor vehicle may be retested according to the  official
     test procedures upon which original approval for that make and model
     vehicle was based.  Any motor vehicle meeting the applicable emission
     standards by either of the aforementioned testing procedures shall
     be deemed to meet the emission standards of the State of California
     and shall be eligible for sale in this state.
                                    -31-

-------
(c)  Commencing with the 1973 model  year, no new motor vehicle shall  be
     sold in California that does not meet the emission standards adopted
     by the board, and any manufacturer who sells, attempts to sell,  or
     causes to be offered for sale a new motor vehicle that fails to  meet
     the applicable emission standards shall be subject to a civil
     penalty of five thousand dollars ($5,000) for each such action.   The
     board and the Department of the California Highway Patrol shall  en-
     force the provisions of this subdivision.  (Added by Stats.  1970,
     Ch. 1295.)
