Governor's Recommendation: Attainment

El Paso

 

*The United States Environmental Protection Agency (EPA) revoked the one-hour ozone standard in all areas, although some areas have continuing obligations under the standard. See ozone history for more information.

**The standard is scheduled to be revoked one year after the effective date of final designations for the 75 ppb standard.

El Paso Attainment and Nonattainment Areas

2008 Eight-Hour Ozone Standard Designation: Attainment/Unclassifiable, effective July 20, 2012 (77 FR 30088) Exit the TCEQ
On March 27, 2008, the EPA lowered the primary and secondary eight-hour ozone NAAQS to 0.075 parts per million (73 FR 16436)Exit the TCEQ. El Paso County was designated attainment/unclassifiable under the 2008 eight-hour ozone NAAQS, effective July 20, 2012.

1997 Eight-Hour Ozone Standard Designation: Attainment, April 30, 2004 (69 FR 23858) Exit the TCEQ
The EPA’s Phase I Implementation Rule for the eight-hour ozone standard directs that areas such as El Paso that were designated nonattainment for the previous one-hour ozone standard but attainment for the eight-hour ozone standard must submit a maintenance plan for eight-hour ozone. The El Paso maintenance plan was approved by the EPA on January 15, 2009 (74 FR 2387)Exit the TCEQ.

Eight-Hour Carbon Monoxide Standard Designation: Attainment, August 4, 2008 (73 FR 45162) Exit the TCEQ
The El Paso CO nonattainment area was restricted to a narrow strip of the city along the Rio Grande, in El Paso County, adjacent to Ciudad Juárez, Mexico. On February 13, 2008, the state submitted a revision to the SIP containing an eight-hour CO maintenance plan to provide for El Paso continued attainment of the eight-hour CO NAAQS until 2020. The redesignation request and maintenance plan were approved by the EPA on August 4, 2008.

PM10 Standard Designation: Moderate Nonattainment, November 6, 1991 (56 FR 56694)
The City of El Paso was designated nonattainment for PM10 and classified as a moderate area upon enactment of the Federal Clean Air Act Amendments of 1990. On November 15, 1991, Texas submitted to the EPA the SIP revision for the El Paso moderate nonattainment area, to demonstrate that the area would attain the PM10 NAAQS no later than December 31, 1994. Modeling of U.S. emissions indicated that the nonattainment area would have been in attainment in 1991, and at the 1994 deadline, if not for emissions transported from outside the United States. Based on §179B of the Federal Clean Air Act, which provides that an area does not have to meet the moderate nonattainment deadline if the state demonstrates attainment if not for emissions from another country, there was no requirement for a reasonable further progress demonstration. The EPA approved the El Paso PM10 SIP revision, effective February 17, 1994 (59 FR 02535)Exit the TCEQ.

National Ambient Air Quality Standards

The EPA has set National Ambient Air Quality StandardsExit the TCEQ(NAAQS) for six principal criteria pollutants: ground-level ozone, lead, carbon monoxide, nitrogen dioxide, sulfur dioxide, and particulate matter.

No later than one year after promulgation of a new or revised NAAQS for any pollutant, the governor must submit designation recommendations to the EPA for all areas of the state. The EPA must then promulgate the designations within two years of promulgation of the revised NAAQS. Areas that do not meet (or contribute to ambient air quality in a nearby area that does not meet) the NAAQS are designated nonattainment. Areas that meet the NAAQS are designated attainment; and areas that cannot be classified based on the available information, unclassifiable.

For ozone, the Federal Clean Air Act establishes nonattainment area classifications ranked according to the severity of the area’s air pollution problem. These classifications—marginal, moderate, serious, severe, and extreme—translate to varying requirements with which Texas and nonattainment areas must comply.
