Nonattainment Areas


Ozone maintenance area in Sunland Park map

Ozone Maintenance Area in Sunland Park

The U.S. EPA designated this area as a marginal nonattaiment for ozone in July 1995. The nearby urban areas of El Paso, TX and Ciudad Juarez, Mexico are suspected of being the source of much of the air pollution in this area. Due to the revocation of the 1-hour ozone standard by EPA in 2004, Sunland Park was redesignated to maintenance status for the 8-hour ozone standard. The maintenance area is bounded by the New Mexico-Texas State line on the east, the New Mexico- Mexico international line on the south, the Range 3E-Range 2E line on the west, and the N3200 latitude line on the north.

The Doña Ana County Natural Events Action Plan (NEAP) for PM10

In December 2000, the Air Quality Bureau submitted a Natural Events Action Plan (NEAP) for Doña Ana County. EPA will excuse those PM10 exceedances caused by uncontrollable natural events, if adequate dust control plans are in place. For Doña Ana County, getting these exceedances excused would keep the area from being designated nonattainment.

Luna County Natural Events Action Plan (NEAP) for PM10

In October 2004, the Air Quality Bureau submitted a Natural Events Action Plan (NEAP) for Luna County. EPA will excuse those PM10 exceedances caused by uncontrollable natural events, if adequate dust control plans are in place. For Luna County, getting these exceedances excused would keep the area from being designated nonattainment.
