          B. Requirements For Use Or Sale  Of Asbestos-Containing Serpentine
             Material
           1.   No  person  shall  use  or apply  serpentine  material  for
                surfacing in California unless the material has been tested
                using  ARB  Test  Method 435  and  determined  to  have  an
                asbestos content of five percent (5.0%) or less.  A written
                receipt or other record  documenting  the  asbestos content
                shall  be  retained  by  any  person  who  uses or  applies
                serpentine material, for a period of at least  seven  years
                from  the date of use or application, and shall be provided
                to the  Air  Pollution  Control Officer or his designee for
                review upon request.

           2.   Any  person  who  sells,  supplies,   or  offers  for  sale
                serpentine material in California shall  provide  with each
                sale  or  supply a written receipt containing the following
                statement:   "Serpentine  material  may  have  an  asbestos
                content  greater  than five percent (5.0%).  It is unlawful
                to  use  serpentine  material   for  surfacing  unless  the
                material has been tested and found  to contain less than or
                equal  to  five  percent (5.0%) asbestos.   All  tests  for
                asbestos content must  use  California  Air Resources Board
                Test Method 435, and a written record documenting  the test
                results  must  be retained for at least seven years if  the
                material is used for surfacing."

           3.   No person shall  sell, supply, or offer for sale serpentine
                material for surfacing  in California unless the serpentine
                material has been tested  using  ARB  Test  Method  435 and
                determined  to  have  an  asbestos  content of five percent
                (5.0%) or less.  Any person who sells,  supplies, or offers
                for  sale  serpentine  material that he or she  represents,
                either orally or in writing,  to  be suitable for surfacing
                or to have an asbestos content that  is five percent (5.0%)
                or  less,  shall  provide  to  each  purchaser   or  person
                receiving  the serpentine material a written receipt  which
                specifies  the   following   information:   the  amount  of
                serpentine material sold or supplied;  the  dates  that the
                serpentine  material  was  produced,  sampled,  tested, and
                supplied   or   sold;  and  the  asbestos  content  of  the
                serpentine material  as measured by ARB Test Method 435.  A
                copy of the receipt must,  at  all  times,  remain with the
                serpentine material during transit and surfacing.

             4. Any  person  who  sells,  supplies,  or  offers  for   sale
                serpentine  material, shall retain for a period of at least
                seven years from  the date of sale or supply, copies of all
                receipts and copies  of  any  analytical  test results from
                asbestos testing of the serpentine material.   All receipts
                and  test  results  shall  be provided to the Air Pollution
                Control Officer or his designee for review upon request.

           5.   If ARB Test Method 435 has been used to perform two or more
                tests on any one volume of serpentine  material, whether by
                the same or a different person, the arithmetic  average  of
                these  test results shall be used to determine the asbestos
                content of the serpentine material.

          C. Exemptions
             1. The provisions  of  subdivision (B)(2) through (B)(5) shall
                not apply to sand and gravel operations.

           2.   The provisions of subdivision  (B)(1)  shall  not  apply to
                roads  located  at serpentine quarries, asbestos mines,  or
                mines located in serpentine deposits.

           3.   The provisions of  subdivision  (B)(1)  shall  not apply to
                maintenance operations on any existing road surfaces, or to
                the  construction  of new roads in serpentine deposits,  as
                long  as  no  additional   asbestos-containing   serpentine
                material is applied to the road surface.

           4.   Emergency Road Repairs
                The  Air  Pollution  Control  Officer may issue a temporary
                exemption from the requirements of subdivision (B)(1) to an
                applicant who demonstrates that  a road repair is necessary
                due to a landslide, flood, or other  emergency and that the
                use of material other than serpentine  is  not feasible for
                this  repair.   The  Air  Pollution  Control Officer  shall
                specify  the  time  during  which such exemption  shall  be
                effective,  provided  that  no exemption  shall  remain  in
                effect longer than six (6) months.

           5.   Bituminous and Concrete Materials
                The  provisions  of subdivision  (B)  shall  not  apply  to
                serpentine material  that is an integral part of bituminous
                concrete, portland cement  concrete, bituminous surface, or
                other similar cemented materials.

           6.   The provisions of subdivision  (B)(1)  shall  not  apply to
                landfill   operations   other   than   the   surfacing   of
                public-access roads dedicated to use by vehicular traffic.
