          SUBPART J  -  Standards of Performance for Petroleum Refineries
                          (Delegation Effective 11-8-76)


               RULE 260.100.  APPLICABILITY AND DESIGNATION OF AFFECTED
                              FACILITY  (Rev. Effective 1/12/79)

               (a)  The provisions of this subpart are applicable to the
          following affected facilities in petroleum refineries:  fluid
          catalytic cracking unit catalyst regenerators, fluid catalytic
          cracking unit incinerator-waste heat boilers, and fuel gas
          combustion devices and all Claus sulfur recovery plants except
          Claus plants of 20 long tons per day (LTD) or less associated
          with a small petroleum refinery.  The Claus sulfur recovery plant
          need not be physically located within the boundaries of a
          petroleum refinery to be an affected facility, provided it
          processes gases produced within a petroleum refinery.

               (b)  Any fluid catalytic cracking unit catalyst regenerator
          or fuel gas combustion device under Section (a) of this rule
          which commences construction or modification after June 11, 1973,
          or any Claus sulfur recovery plant under Section (a) of this rule
          which commences construction or modification after October 4,
          1976, is subject to the requirements of this subpart.


               RULE 260.101.  DEFINITIONS  (Rev. Effective 5/1/81)

               As used in this subpart, all terms not defined herein shall
          have the meaning given them in Subpart A.

               (a)  "Petroleum Refinery" means any facility engaged in
          producing gasoline, kerosene, distillate fuel oils, residual fuel
          oils, lubricants, or other products through distillation of
          petroleum or through redistillation, cracking or reforming of
          unfinished petroleum derivatives.

               (b)  "Petroleum" means the crude oil removed from the earth
          and the oils derived from tar sands, shale, and coal.

               (c)  "Process Gas" means any gas generated by a petroleum
          refinery process unit, except fuel gas and process upset gas as
          defined in this rule.

               (d)  "Fuel Gas" means any gas which is generated by a
          petroleum refinery and which is combusted.  Fuel gas also
          includes natural gas when the natural gas is combined and com-
          busted in any proportion with a gas generated at a refinery.
          Fuel gas does not include gases generated by catalytic cracking
          unit, catalyst regenerators and fluid coking burners.  (Effective
          5/1/81)

               (e)  "Process Upset Gas" means any gas generated by a
          petroleum refinery process unit as a result of startup, shutdown,
          upset or malfunction.
               (f)  "Refinery Process Unit" means any segment of the
          petroleum refinery in which a specific processing operation is
          conducted.

               (g)  "Fuel Gas Combustion Device" means any equipment, such
          as process heaters, boilers and flares used to combust fuel gas,
          but does not include facilities in which gases are combusted to
          produce sulfur or sulfuric acid.

               (h)  "Coke Burn-Off" means the coke removed from the surface
          of the fluid catalytic cracking unit catalyst by combustion in
          the catalyst regenerator.  The rate of coke burn-off is
          calculated by the formula specified in Rule 260.106.

               (i)  "Claus Sulfur Recovery Plant" means a process unit
          which recovers sulfur from hydrogen sulfide by a vapor-phase
          catalytic reaction of sulfur dioxide and hydrogen sulfide.

               (j)  "Oxidation Control System" means an emission control
          system which reduces emissions from sulfur recovery plants by
          converting these emissions to sulfur dioxide.

               (k)  "Reduction Control System" means an emission control
          system which reduces emissions from sulfur recovery plants by
          converting these emissions to hydrogen sulfide.

               (l)  "Reduced Sulfur Compounds" means hydrogen sulfide
          (H2S), cabonyl sulfide (COS) and carbon disulfide (CS2).

               (m)  "Small Petroleum Refinery" means a petroleum refinery
          which has a crude oil processing capacity of 50,000 barrels per
          stream day or less and which is owned or controlled by a refinery
          with a total combined crude oil processing capacity of 137,500
          barrels per stream day or less.


               RULE 260.102.  STANDARD FOR PARTICULATE MATTER
                                        (Rev. Effect. 1/12/79)

               (a)  On and after the date on which the performance test
          required to be conducted by Rule 260.8 is completed, no owner or
          operator subject to the provisions of this subpart shall
          discharge or cause the discharge into the atmosphere from any
          fluid catalytic cracking unit catalyst regenerator:

                    (1)  Particulate matter in excess of 1.0 kg/1000 kg
               (1.0 lb/1000 lb) of coke burn-off in the catalyst

          cracking unit catalyst regenerator pass through an incinerator or
          waste heat boiler in which auxiliary or supplemental liquid or
          solid fossil fuels are burned, particulate matter in excess of
          that permitted by Subsection (a)(1) of this rule may be emitted
          to the atmosphere, except that the incremental rate of
          particulate emissions shall not exceed 0.18 g/million Cal (0.10
          lb/million Btu) of heat input attributable to such liquid or
          solid fuel.


               RULE 260.103.  STANDARD FOR CARBON MONOXIDE

               On and after the date on which the performance test required
          to be conducted by Rule 260.8 is completed, no owner or operator
          subject to the provisions of this subpart shall discharge or
          cause the discharge into the atmosphere from the fluid catalytic
          cracking unit catalyst regenerator any gases which contain carbon
          monoxide in excess of 0.050 percent by volume.


               RULE 260.104.  STANDARD FOR SULFUR DIOXIDE  (Rev. Effect.

          which is released to the flare as a result of relief valve
          leakage, is exempt from this section .

               (b)  The owner or operator may elect to treat the gases
          resulting from the combustion of fuel gas in a manner which
          limits the release of SO2 emissions as effectively as compliance
          with the requirements of Section (a) of this rule.

                    oxygen on a dry basis if emissions are controlled by a
                    reduction control system not followed by incineration.
