(Approved by EPA 09/26/97 (62 FR 50518) at 52.1620(c)(66) effective 11/25/97. Dates in brackets within the regulation are State effective dates.)
100. ISSUING AGENCY: Environmental Improvement Board. [11-30-95]
101. SCOPE: All geographic areas within the jurisdiction of the Environmental Improvement Board. [11-30-95]
102. STATUTORY AUTHORITY: Environmental Improvement Act, NMSA 1978, Section 74-1-8(A)(4) and Air Quality Control Act, NMSA 1978, Sections 74-2-1 et seq., including specifically, Section 74-2-5(A) and (B). [11-30-95]
103. DURATION: Permanent. [11-30-95]
104. EFFECTIVE DATE: November 30, 1995. [11-30-95]
105. OBJECTIVE: The objective of this Part is to establish ambient air quality standards for the areas of New Mexico under the jurisdiction of the Environmental Improvement Board. [11-30-95]
106. AMENDMENT AND SUPERSESSION OF PRIOR REGULATIONS: This Part amends and supersedes Air Quality Control Regulations ("AQCR") 200 - Preamble and 201 - Ambient Air Quality Standards last filed January 27, 1970 and June 15, 1981, respectively.
A. All references to AQCR 200 or 201 in any other rule shall be construed as a reference to this Part.
B. The amendment and supersession of AQCR 200 and 201 shall not affect any administrative or judicial enforcement action pending on the effective date of such amendment nor the validity of any permit issued pursuant to AQCR 200 or 201. [11-30-95]
107. DEFINITIONS: In addition to the terms defined in Part 2 - Definitions, as used in this Part: [11-30-95]
"Part" means an air quality control regulation under Title 20, Chapter 2 of the New Mexico Administrative Code, unless otherwise noted; as adopted or amended by the Board. [11-30-95]
108. PREAMBLE: Ambient Air Quality Standards are not intended to provide a sharp dividing line between air of satisfactory quality and air of unsatisfactory quality. They are, however, numbers which represent objectives that will preserve our air resources.
It is understood that at certain times, due to unusual meteorological conditions, these standards may be exceeded for short periods of time without the addition of specific pollutants into the atmosphere. The adoption of these statewide ambient air quality standards does not prohibit the promulgation of standards for specific areas, functions, and conditions within the state such as air sheds, municipalities, and certain counties, as authorized under the Act.
As scientific data accumulates on the effects of a contaminant, these standards may be revised or additional standards added. [11-30-95]
109. TOTAL SUSPENDED PARTICULATES:
A. The maximum allowable concentrations of total suspended particulate in the ambient air are as follows:
MAXIMUM CONCENTRATION
