Impact On Policy

A number of TERC projects were cited in the latest State Implementation Plan (SIP), the ozone-reduction plan for the Houston area's attainment of the one hour standard. Some of the studies were included in appendices to the plan. More details about each TERC project can be obtained by going to Completed Projects in the Air Quality Research Projects section of the web site.
