COASTAL BEND AIR QUALITY PARTNERSHIP (Formally Corpus Christi Air Quality Group)

Originally established in 1995 to address National Ambient Air Quality Standards (NAAQS) ozone attainment issues for the Corpus Christi airshed. Participants in the Partnership include individuals from area municipal and county government, business and industry, local universities, public agencies, a regional planning organization, regional development corporations, the military and the news media. The broad stakeholder representation within the Group works collaboratively to design and deliver effective strategies to maintain NAAQS for ozone that are suitable for the Corpus Christi area. The Group is Chaired by Gretchen Arnold. The Partership participants include the City of Corpus Christi, Nueces County, Corpus Christi Regional Transportation Authority, Corpus Christi Metropolitan Planning Organization and the Port of Corpus Christi Authority provide funding annually to sponsor Chair functions of the Partnership. The partnership meets quarterly and all meetings are open to the public.

The goal of the Corpus Christi airshed participation in the Ozone Advance Program is to continue the area’s successful history of maintaining healthy air quality and to encourage voluntary air emission reductions that keep Nueces County and San Patricio County in attainment with the NAAQS for ozone.

The following are the Corpus Christi Urban Airsheld Annual Ozone Advance Reports:


Corpus Christi Ozone Advance Annual Report: May 2018 - May 2019 Corpus Christi Ozone Advance Annual Report: May 2017 - May 2018 Corpus Christi Ozone Advance Annual Report: May 2016 - April 2017 Corpus Christi Ozone Advance Annual Report: May 2015 - April 2016


This report fulfills the annual reporting requirements of the 8 Hour O3FLEX Memorandum of Agreement approved on October 23, 2007 for the Corpus Christi Air Shed. This report includes the required annual assessment of ozone monitoring data and analysis for the period of August 1, 2011 – April 30, 2012; the effectiveness of voluntary or mandatory control measures in conjunction with improved technical understanding of the ozone problem during the period of August 1, 2011 – April 30, 2012; recommended mid-course corrections to action plan; and, latest information on implementation of control measures.

Nueces and San Patricio Counties are considerd the urban airshed.

Two adjoining counties, Nueces County and San Patricio County in Texas, contain a large urbanized area with a number of industrial point sources of air emissions and a growing concentration of mobile sources. The two counties are home to the nation's fifth busiest deep-water port, a large industrial and petrochemical complex, a major military base, and a network of highways including the Interstate Highway System that facilitates commerce and a thriving tourism industry. Nueces County and San Patricio County are considered an urban airshed (the Corpus Christi Urban Airshed) in which air emissions from sources in both counties interact to influence the level of ambient air pollution in the community. Control of ambient air quality requires a strategy that considers sources of air emissions in both counties.

The preparation of this report has been financed in part through grant[s] from the Federal Highway Administration and Federal Transit Administration, U.S. Department of Transportation, under the State Planning and Research Program, Section 505 [or Metropolitan Planning Program, Section 104(f)] of Title 23, U.S. Code.
