N.M. Code R. § 20.2.35.111 – Stack Height

A. The owner or operator of a natural gas processing plant shall not permit, cause, suffer or allow sulfur compounds to be emitted to the atmosphere unless the sulfur compound emission is from a stack of a sufficient physical height to prevent concentrations of sulfur compounds near ground level equal to or exceed any state or federal ambient air standard. The necessary physical stack height shall be determined by the following graph in 20.2.35.115 NMAC (Figure 1) or through the use of dispersion modeling approved by the department.
B. If the natural gas processing plant is an existing natural gas processing plant, the requirements of this section shall not apply to that existing natural gas processing plant until January 1, 1977.
C. By January 1, 1977, any person owning or operating an existing natural gas processing plant must file with the department the following:
(1) the height of all stacks from which sulfur is emitted;
(2) the quantity of the sulfur emitted from each stack;
(3) the exit gas temperature for each stack;
(4) the total mass flow rate of the stack effluent gases (for flares, the total effluent mass flow rate shall consist of the stack effluent mass flow rate plus that amount of air required for complete combustion); and
(5) any other information the department deems necessary to determine whether or not the physical height of any stack from which sulfur is emitted complies with the requirements of this subsection.
