New Mexico Air Quality Permit for Construction Activities (15-NM-a(1))

Information current as of 2020
In New Mexico, bulk transmission project construction activities and equipment may require either a Notice of Intent or an Air Quality Construction Permit from the New Mexico Environment Department (NMED), Air Quality Bureau. The temporary use of a portable diesel generator that qualifies as a “nonroad engine” under 40 C.F.R. § 89.2 is considered a “portable stationary source” under N.M. Code R. § 20.2.72.7; New Mexico Environment Department – The Regulation of Non-Road Engines Under 20.2.70, 20.2.72, and 20.2.73 NMAC. NMED requires that nonroad engines undergo an applicability analysis in order to determine whether an Air Quality Construction Permit is required pursuant to N.M. Code R. § 20.2.72.200. New Mexico Environment Department – The Regulation of Non-Road Engines Under 20.2.70, 20.2.72, and 20.2.73 NMAC. Other equipment brought onsite temporarily may also require a permit and should be included in the applicability analysis. Forklifts, courier vehicles, front end loaders, graders, carts, maintenance trucks, and fugitive emissions from fleet vehicle refueling operations are exempt from permitting.


A developer engaged in construction activities over an area of one acre or greater must also comply with fugitive dust rules contained in N.M. Code R. § 20.2.23. N.M. Code R. § 20.2.23.108(A)(1). NMED’s fugitive dust rules require a developer to:

  • Prevent visible emission from fugitive dust sources that pose a threat to public health or interfere with public welfare; N.M. Code R. § 20.2.23.109.
  • Prevent visible emissions from construction or bulk material handling or storage from crossing the property lines from which it originates; N.M. Code R. § 20.2.23.110.
  • Utilize one or more control measures utilize one or more fugitive dust control measures in accordance with N.M. Code R. § 20.2.23.111; and
  • Develop and maintain a fugitive dust control plan in accordance with N.M. Code R. § 20.2.23.112, which must be available to NMED upon request.


Note: If a developer’s project extends into City of Albuquerque or the County of Bernalillo, the developer should consult the Albuquerque-Bernalillo County Air Quality Control Board, which has its own air quality permitting program. The developer must apply for applicable permits with that program. New Mexico Environment Department – Air Quality Bureau Jurisdiction.



Air Quality Permit for Construction Activities Process


15-NM-a.1 — Consult with the New Mexico Environment Department (NMED)

A developer may consult with NMED in order to determine whether a nonroad engine (e.g., a temporary, portable diesel generator) or other equipment will require either a Notice of Intent pursuant to N.M. Code R. § 20.2.73.200 or an Air Quality Construction Permit pursuant to N.M. Code R. § 20.2.72.200. New Mexico Environment Department – The Regulation of Non-Road Engines Under 20.2.70, 20.2.72, and 20.2.73 NMAC.

A developer must submit a Notice of Intent to NMED if the developer intends to construct a new stationary source, even a temporary one, that has a potential emission rate greater than 10 tons per year (tpy) of any regulated air contaminant or 1 tpy of lead. N.M. Code R. § 20.2.73.200(A). A developer must submit an Application for an Air Quality Construction Permit (Application) prior to constructing or operating any stationary source with a potential to emit greater than 10 pounds per hour (pph) or 25 tons per year (tpy) of any regulated air pollutant with a National or New Mexico Ambient Air Quality Standard or if the source meets any other applicability requirement contained in N.M. Code R. § 20.2.73.200(A)(1)–(6). New Mexico’s air quality regulations define “stationary source” as including “portable stationary sources,” such as nonroad engines. N.M. Code R. §§ 20.2.73.7(N), (S); 20.2.72.7(X), (EE); New Mexico Environment Department – The Regulation of Non-Road Engines Under 20.2.70, 20.2.72, and 20.2.73 NMAC.

15-NM-a.2 — Submit Notice of Intent

A developer must submit a Notice of Intent to NMED if the developer intends to construct a new stationary source, even a temporary one, that has a potential emission rate greater than 10 tons per year (tpy) of any regulated air contaminant or 1 tpy of lead. N.M. Code R. § 20.2.73.200(A).
