Universal Citation: 20 NM Admin Code 20.2.35.109

Current through Register Vol. 35, No. 18, September 24, 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.
