The 2001 amendment, effective June 15, 2001, substituted "listed" for "classified" in Subsection H; and rewrote Subsection P, which formerly read "'potential emission rate' means the emission rate of a source at its maximum capacity in the absence of air pollution control equipment that is not vital to production of the normal product of the source or to its normal operation;".

The 1992 amendment, effective March 5, 1992, deleted former Subsections C and D, defining "board" and "delayed compliance order"; rewrote former Subsection E and redesignated it as present Subsection C; redesignated former Subsection F as present Subsection D, while substituting therein "a local agency" for "the department"; redesignated former Subsection G as present Subsection E, while inserting therein "environmental improvement board or the local" and "the local authority or the local agency"; deleted former Subsection H, defining "environmental improvement division"; rewrote former Subsection I and redesignated it as present Subsection F; redesignated former Subsections J and K as present Subsections G and H; added present Subsections I, J and K; inserted "environmental improvement board or the local" in Subsection M(3); rewrote Subsection N; added present Subsection R; redesignated former Subsections R through U as present Subsections S through V; added Subsection W; and made minor stylistic changes throughout the section.

Board may not expand definition of "air pollution" from "reasonable probability" of injury to health to a mere showing that condition "tends to cause harm." Duke City Lumber Co. v. N.M. Envtl. Improvement Bd., 1984-NMSC-042, 101 N.M. 291, 681 P.2d 717.

Air Quality Standards' margin of safety does not contemplate excursions beyond legal limits. — Petitioner's argument that Congress, by allowing an adequate margin of safety, not only contemplated but countenanced occasional excursions beyond the limits of the National Ambient Air Quality Standards is meritless since it is clear that the margin of safety protects against effects which have not yet been uncovered by research or whose medical significance is a matter of disagreement. Duke City Lumber Co. v. N.M. Envtl. Improvement Bd., 1984-NMCA-058, 102 N.M. 8, 690 P.2d 451.

Board may rely on division's modeling results to deny variance application. — The environmental improvement board may rely on the environmental improvement division's modeling results, showing particulate concentrations in excess of the legal limit, in arriving at its decision to deny a lumber company's application for a variance from air quality control regulations. Duke City Lumber Co. v. N.M. Envtl. Improvement Bd., 1984-NMCA-058, 102 N.M. 8, 690 P.2d 451.

Application of reasonable probability of injury standard not required during permitting process. — Where the city of Albuquerque environmental health department (EHD) issued an authority-to-construct permit to an oil company pursuant to the New Mexico Air Quality Control Act (AQCA), 74-2-1 to 74-2-17 NMSA 1978, and where the Albuquerque-Bernalillo county air quality control board (board) upheld the EHD's issuance of the permit, and where plaintiff appealed the board's order, claiming that EHD and the board each failed to apply a "reasonable probability of injury" standard when evaluating the permit, the board did not err in upholding EHD's issuance of the authority-to-construct permit, because 74-2-7 NMSA 1978 directs EHD and the board to determine whether local, state, and federal air pollution standards or federal regulations have been violated, but does not impose on EHD or the board a requirement to independently apply the reasonable probability of injury standard when considering whether to grant a permit. Southwest Organizing Project v. Albuquerque-Bernalillo Cnty. Air Quality Control Bd., 2021-NMCA-005.

Requirement to consider community testimony met during permitting process. — Where the city of Albuquerque environmental health department (EHD) issued an authority-to-construct permit to an oil company pursuant to the New Mexico Air Quality Control Act (AQCA), 74-2-1 to 74-2-17 NMSA 1978, and where the Albuquerque-Bernalillo county air quality control board (board) upheld the EHD's issuance of the permit, and where plaintiff appealed the board's order, claiming that EHD, during the application process, and the board, at the later adjudicatory hearing, were required to consider community testimony regarding the oil company's effect on local resident quality of life, the board did not err in upholding EHD's issuance of the authority-to-construct permit, because EHD, during the initial application process, met the public comment requirement by holding a public information hearing, accepting pubic testimony about concerns for quality of life, and addressing written comments submitted before and during the hearing, and the board, during the hearings following the petition of EHD's decision to grant the permit, similarly permitted public testimony. EHD and the board, however, were not required to specifically address public testimony regarding quality of life issues in resolving the permit application. Southwest Organizing Project v. Albuquerque-Bernalillo Cnty. Air Quality Control Bd., 2021-NMCA-005.

Public nuisance laws deemed alternative means of enforcement. — Where air quality standards or regulations have not been established as to what constitutes "air pollution" and thus no violation of this article or regulations and standards is apparent, New Mexico's public nuisance law may provide an alternative means for the environmental improvement division to abate noxious odors. 1978 Op. Att'y Gen. No. 78-12.
