Current through Register Vol. 35, No. 13, July 16, 2024
A. The owner or operator of an existing
				natural gas processing plant that releases an average of ten tons a day or
				greater of sulfur in plant processes and that has an off-gas stream that
				undiluted contains greater than 20 mole percent hydrogen sulfide shall not
				permit, cause, suffer or allow at any time sulfur emissions to the atmosphere
				in excess of 10 pounds of sulfur for every 100 pounds of sulfur released in
				plant processes.
B. The owner or
				operator of an existing natural gas processing plant that releases an average
				of ten tons a day or greater of sulfur in plant processes and that has an
				off-gas stream that undiluted contains less than or equal to 20 mole percent
				hydrogen sulfide shall not permit, cause, suffer or allow at any time sulfur
				emissions to the atmosphere in excess of 12 pounds of sulfur for every 100
				pounds of sulfur released in plant processes.
C. The owner or operator of an existing
				natural gas processing plant that releases an average of 7.5 or more tons a day
				but less than 10 tons a day of sulfur in plant processes and has an off-gas
				stream that undiluted contains greater than 20 mole percent hydrogen sulfide
				shall not permit, cause, suffer or allow at any time sulfur emissions to the
				atmosphere in excess of 10 pounds of sulfur for every 100 pounds of the sulfur
				released in plant processes.
D. The
				owner or operator of an existing natural gas processing plant that releases an
				average of 7.5 or more tons a day but less than 10 tons a day of sulfur in
				plant processes and has an off-gas stream that undiluted contains less than or
				equal to 20 mole percent hydrogen sulfide shall not permit, cause, suffer or
				allow sulfur emissions to the atmosphere in excess of 12 pounds of sulfur for
				every 100 pounds of sulfur released in plant processes.
E. The owner or operator of an existing
				natural gas processing plant that sends residue gas containing greater than
				0.25 grains hydrogen sulfide per 100 cubic feet of gas to a facility, other
				than the natural gas processing plant, for the purpose of residue gas
				purification; shall not permit, cause, suffer or allow sulfur emissions to the
				atmosphere, in excess of 10 pounds of sulfur for every 100 pounds of sulfur
				released in plant processes; unless the natural gas processing plant releases
				less than 2 1/2 tons a day of sulfur in plant processes.
F. The owner or operator of an existing
				natural gas processing plant that is governed by a sulfur emission limitation
				of an Air Quality Control Regulation shall not permit, cause, suffer or allow
				gas coming off any off-gas sweetening regeneration unit or other sulfur
				releasing unit to be sent to a facility other than the natural gas processing
				plant for the purpose of sulfur recovery or disposal:
(1) unless all the gas coming off a gas
				sweetening regeneration unit or other sulfur releasing unit is sent to the
				facility other than the natural gas processing plant, except mercaptan gas, and
				the amount of sulfur in the off-gas stream from fuel burning equipment does not
				exceed the quantity of sulfur that would exist if the sulfur content of the gas
				used for fuel was 10 grains of sulfur per 100 standard cubic feet of fuel gas;
				or
(2) unless only a portion of the
				gas coming off a gas sweetening regeneration unit or other sulfur releasing
				unit is sent to the facility other than the natural gas processing plant; and
(a) if the natural gas processing plant
				releases a average of 7.5 tons a day or greater of sulfur in plant processes
				and has an off-gas stream that undiluted contains greater than 20 mole percent
				hydrogen sulfide, sulfur emissions from the existing natural gas processing
				plant do not exceed 10 pounds of sulfur for every 100 pounds of sulfur that are
				released in plant processes but not sent for sulfur recovery or disposal to
				another facility; or
(b) if the
				natural gas processing plant releases a average of 7.5 tons a day or greater of
				sulfur in plant processes and has an off-gas stream that undiluted contains
				less than or equal to 20 mole percent hydrogen sulfide, sulfur emissions from
				the existing natural gas processing plant do not exceed 12 pounds of sulfur for
				every 100 pounds of sulfur that are released in plant processes but not sent
				for sulfur recovery or disposal to another facility.
