Corpus Christi: Ozone Planning

Events and activities related to the Corpus Christi area’s compliance with the National Ambient Air Quality Standard for ground-level ozone.

Corpus Christi Eight-Hour Ozone Flex Plan

In 2004, the U.S. Environmental Protection Agency designated the Corpus Christi area as in attainment for the the 1997 eight-hour ozone National Ambient Air Quality Standard (NAAQS). Stakeholders in Nueces and San Patricio Counties expressed a desire to develop an Ozone Flex (O3 Flex) program for the eight-hour ozone standard and had a letter of intent sent to the EPA from the Mayor of Corpus Christi on October 4, 2004. In response to Corpus Christi’s initiative, the EPA issued national guidelines for the Eight-Hour O3 Flex Program on May 18, 2006, similar to the previous guidance for the One-Hour O3 Flex Program. The purpose of the Eight-Hour O3 Flex program is to encourage eight-hour ozone attainment areas nationwide to reduce ozone emissions to continue to meet the NAAQS for ozone. All parties signed the five-year agreement in 2007.
