SDAPCD RULE 53 SPECIFIC CONTAMINANTS          
LAST REVISED 09/21/83

          
          RULE 53.  SPECIFIC CONTAMINANTS    (Rev. Effect. 9/21/83)

               (a)  APPLICABILITY

               This rule is applicable to the following:

                    (1)  Sulfur recovery plants and others sources of
               gaseous sulfur emissions where the sulfur compounds emitted
               are not products of fuel combustion.

                    (2)  Except as provided for in Section (b) of this
               rule, all sources of particulate matter discharged into the
               atmosphere from the burning of any kind of material
               containing carbon in a free or combined state.

               (b)  EXEMPTIONS

               The provisions of Subsection (c)(2) of this rule shall not
          apply to stationary liquid fueled piston-type internal combustion
          engines.

               (c)  STANDARDS

               A person shall not discharge into the atmosphere from any
          single source of emission whatsoever any one or more of the
          following contaminants, in any state or combination thereof,
          exceeding in concentration at the point of discharge:

                    (1)  Sulfur compounds calculated as sulfur dioxide
               (SO2):  0.05 percent by dry volume.

                    (2)  Combustion particulates:  except as provided in
               Subsections (c)(3) and (c)(4) of this rule, 0.1 grains per
               dry standard cubic foot (0.231 grams per dry standard cubic
               meter) of gas which is standardized to 12 percent of carbon
               dioxide (CO2) by volume.  In measuring the combustion
               particulates from incinerators used to dispose of
               combustible refuse by burning, the carbon dioxide (CO2)
               produced by combustion of any liquid or gaseous fuels shall
               be excluded from the adjustment to 12 percent of carbon
               dioxide (CO2) by volume.

                    (3)  Combustion particulates from incinerators with a
               rated capacity of 100 pounds per hour or less:  0.3 grains
               per dry standard cubic foot (0.694 grams per dry  standard
               cubic meter) of gas which is standardized to 12 percent of
               carbon dioxide (CO2) by volume.  In measuring the combustion
               particulates from incinerators used to dispose of
               combustible refuse by burning, the carbon dioxide (CO2)
               produced by combustion of any liquid or gaseous fuels shall
               be excluded from the adjustment to 12 percent of carbon
               dioxide (CO2) by volume.

                    (4)  Combustion particulates from the testing of jet
               engines in test cells:  0.07 grains per dry standard cubic
               foot (0.16 grams per dry standard cubic meter) of gas
               standardized to 1 percent of carbon dioxide (CO2).
