Section 20.2.72.401 - DEFINITIONS

In addition to the definitions in 20.2.72.7 NMAC, the following definitions apply to 20.2.72.400 NMAC - 20.2.72.499 NMAC:

A. "Best available control technology" means an emission limitation based on the maximum degree of reduction in emissions of each contaminant subject to this Part which the Secretary (or the Board), on a case-by-case basis, taking into consideration the cost of achieving such emission reduction, and any non-air quality health and environmental impacts resulting from the use of such technology, determines is achievable for the source, through application of measures, processes, methods, systems, or techniques including, but not limited to, measures which:

(1) Reduce the volume of such pollutants through process changes, substitutions of materials, or other modifications, or

(2) Enclose systems or processes to eliminate emissions, or

(3) Collect, capture or treat such pollutants when released from a process, stack, storage, or fugitive emission point.

B. "Existing source" means any source, the construction or modification of which was commenced on or before December 31, 1988.

C. "Fixed capital costs" means that capital needed to provide all the depreciable components.

D. "New source" means any source, the construction of which is commenced after December 31, 1988. The term does not include any new source which is integrally related with and integrally connected to the process of an existing source. The term includes the reconstruction of an existing source.

E. "Occupational Exposure Limit" or "OEL" means the eight-hour time weighted average concentration specified for workroom air in "Threshold Limit Values and Biological Exposure Indices for 1986-1987" as adopted by the American Conference of Governmental Industrial Hygienists, or for compounds not assigned an OEL in that document, the minimum detection limit specified in the National Institute for Occupational Safety and Health "Manual of Analytical Methods", Third Edition.

F. "Oil and gas production facilities" means facilities for the exploration, development, production, treatment, separation, storage, transport, and sale of unrefined hydrocarbons, natural gas liquids, and CO2 (e.g., major SIC group 13, oil and gas extraction, SIC industry group no. 4612, crude, petroleum, pipeline and SIC industry no. 4922, natural gas transmission). Natural gas processing plants and refineries are not included for purposes of this definition.

G. "Reconstruction" means a modification which results in the replacement of the components or addition of integrally related equipment to an existing source to such an extent that the fixed capital cost of the new components or equipment exceeds 50 percent of the fixed capital cost that would be required to construct a comparable entirely new facility.

H. "Toxic air pollutant" means any air contaminant in 20.2.72.502 NMAC.
