The air quality state implementation plan (SIP) is an enforceable plan developed at the state level that explains how the state will comply with air quality standards according to the Federal Clean Air Act.
The Federal Clean Air Act (FCAA) is the legal foundation for the national air pollution control program. The FCAA requires each state to produce and regularly update a SIP. The FCAA also requires that SIPs include a description of control strategies, or measures to deal with pollution, for areas that fail to achieve national ambient air quality standards (NAAQS). Finally, this Act grants powers of enforcement to the United States Environmental Protection Agency (EPA).
NAAQS are established by the EPA as directed by the FCAA. The Houston-Galveston-Brazoria region is in non-attainment for the 2008 8-hour ozone standard and for the 2015 8-hour ozone standard. The latest SIP revisions for our region can be found at: https://www.tceq.texas.gov/airquality/sip/sipplans.html
The SIPs are developed to protect human health. Ground-level ozone is harmful because it can trigger a variety of health problems:
These health problems can be more serious for children, the elderly, and people of all ages who have lung diseases such as asthma.
