Coastal Bend Air Quality Partnership Background
The Coastal Bend Air Quality Partnership (formerly the Corpus Christi Air Quality Group) was established in 1995 when Corpus Christi was very close to violating ozone air quality standards set forth by the Environmental Protection Agency (EPA). The Partnership works to stay abreast of local ozone levels, seek funding for air quality programs, and identify and implement programs best suited to reduce ozone-causing emissions in our air. Examples of programs that the Partnership has implemented are research monitors and analysis, vehicle emissions tests and repair vouchers, community education, installation of pollution prevention equipment at area industry and more. For more detail on the many programs that the Partnership has provided, please see the Partnership’s Ozone Advance report of activities. https://www.epa.gov/advance/texas-corpus-christi
The purpose of the Partnership and its activities is to keep Nueces and San Patricio county air healthy and in compliance with EPA standards. Participants in the Partnership include individuals from area municipal and county government, business and industry, local universities, public agencies, a regional planning organization, the military and the news media.
The Partnership meets four times a year. All meetings are open to the public. To request to be included in meeting notifications, email the Chair, Gretchen Arnold at firstname.lastname@example.org.
Corpus Christi Airshed Definition
The Corpus Christi Urban airshed is made up of both Nueces and San Patricio Counties. Nueces County and San Patricio County are defined by the EPA and the Texas Commission on Environmental Quality (TCEQ) as an urban airshed in which air emissions from sources in both counties interact to influence the level of air pollution in the Corpus Christi community. Control of air quality requires a strategy that considers sources of air emissions in both counties.

Corpus Christi Ozone Status and Trending
Corpus Christi urban airshed air complies with EPA National Ambient Air Quality Standards (NAAQS) standards for ozone. Corpus Christi urban airshed’s compliance with ozone standards is determined by two continuously operating air monitors (CAMS) operated by the TCEQ. These two monitors; CAMS 21 and CAMS 4 continuously measure air for ozone. CAMS 4 is located at 902 Airport Road and data generated from CAMS 4 can be found at http://www17.tceq.texas.gov/tamis/index.cfm?fuseaction=report.view_site&CAMS=4 CAMS 21 is located at 9866 LaBranch and data generated by CAMS 21 can be found at http://www17.tceq.texas.gov/tamis/index.cfm?fuseaction=report.view_site&CAMS=21
In order for our air to be compliant with EPA standards for ozone, the air monitored and measured by both CMAS 4 and CAMS 21 must be under the level of 70 parts per billion over an 8-hour period and averaged over a 3 year period of the 4th high average in each year included in the average.

The current value of ozone levels in the Corpus Christi airshed are 61 parts per billion at CAMS 4 and 60 parts per billion at CAMS 21. The airshed has experienced an overall decreasing trend in ozone values.
Corpus Christi Urban Airshed Participation in EPA Ozone Advance Program
The Partnership is a participant in the EPA Ozone Advance Program; a program that commits an area to voluntary air emission reduction activities. More about the EPA Ozone Advance Program can be found at https://www.epa.gov/advance.
Copies of annual Ozone Advance reports citing area voluntary emission reduction activities from 2015 – 2019 can be found at https://www.epa.gov/advance/texas-corpus-christi
Emission Reduction Opportunities and Recommendations
There are numerous small adjustments to the way we get around town to the way we do business that the public, business and industry can make that reduce the ozone forming pollutants that are released into our air. Please review the checklist of emission reduction recommendations and commit to just a few adjustments that can make a big difference.
