              101  PURPOSE:   To limit asbestos emissions to the atmosphere
                   from serpentine  rock  by prohibiting the use or sale of
                   serpentine rock containing  more  than  5%  asbestos for

                   geologist must document  precisely  how  the  serpentine
                   content of the material in question was determined.

                           percent  (5%)  or  less.  All tests for asbestos
                           content must use California  Air Resources Board
                           Test   Method   435,   and   a  written   record

              501  TEST  METHOD:  All serpentine material supplied, sold or

                   testing  of the serpentine material.  All  receipts  and
                   test results  shall  be  provided  to  the Air Pollution
                   Control Officer for review upon request.
