          RULE 4.5  Particulate Matter
          *컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴*

          No person shall discharge from any non-combustion source particu-
          late  matter  in  excess of 0.30 grains per cubic foot of exhaust
          gas at standard conditions,  or  in any one hour total quantities
          in excess of the amount shown in TABLE  I,  whichever is the more
          restrictive condition.

                To use the Table I (see next page), take  the process
                weight per hour, as such is defined in Rule 1.2. 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/she will divide  the
                weight of all materials  in  the specific process (in
                this example, 1500 lbs.  3) giving  a process weight
                per hour of 500 lbs.  The table shows  that  (A)  may
                not  discharge  more  than  1.77 lbs. 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.
