Texas proposes comprehensive Houston-area clean air plan

11 August 2000

On 9 August 2000, the Texas Natural Resource Conservation Commission (TNRCC) approved a package of pollution-reduction measures for the Houston-Galveston ozone nonattainment area, along with statewide and Central and East Texas measures, designed to clean up the air and bring the region into compliance with federal clean air standards.

The plan is expected to reduce nitrogen oxide (NOx) emissions by 75%, and Volatile Organic Compounds (VOCs) by more than 40% in the Houston area. Both NOx and VOCs are ozone precursors.

This action opened a public comment period for the plan which ends September 25. The Commission is expected to finalize the plan on December 6. “These air quality improvement measures are the toughest ever considered in Texas, and some of the toughest ever considered in the nation,” said TNRCC Chairman Robert Huston.

The approved proposals included a range of emission control measures for both stationary and mobile sources. The following are some of the proposals, which are pertinent to engine emissions:
