On December 15, 2012, the Corpus Christi Air Quality Group (Group) submitted a letter of intent to the Environmental Protection Agency (EPA) to participate in an Ozone Advance Program. In May 2014, the Group submitted a Path Forward Letter to the EPA initiating Corpus Christi’s participation in an Ozone Advance Program with the EPA. This Path Forward Letter identified voluntary emission reduction activities that would be undertaken over a two-year period of time; scheduled for completion in May of 2016. In May of 2015, the Group submitted a report to the EPA on Year 1 Ozone Advance activities that took place from May 2014 – April 2015. In July of 2016, the Group submitted a report to the EPA on Year 2 Ozone Advance activities that took place from May 2015 – April 2016. In addition to reporting on the Path Forward Letter committed voluntary emission reduction activities, each year’s report included commitments that “look forward” to future years beyond the Path Forward committed activities and schedule.

The following are the annual reports for the Corpus Christi Ozone Advance Year 3 activities. Year 3 activities include a continuation of the Path Forward Letter is commitments as well as additional “looking forward” commitments that took place from May 2015 – May 2018.

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.
