Proposed SIP Revisions and Public Hearing Information

The Texas Commission on Environmental Quality (commission) offers public hearings to receive testimony regarding proposed SIP revisions. The hearings are structured for the receipt of oral or written comments by interested persons. Open discussion is not permitted during the hearings; however, commission staff members are available to discuss the proposal 30 minutes prior to each hearing.

Persons who have special communication or other accommodation needs who are planning to attend a hearing should contact Jamie Zech, Air Quality Division at (512) 239-3935 or 1-800-RELAY-TX (TDD). Requests should be made as far in advance as possible.

Written comments on proposed SIP revisions may be submitted through the eComments system during the public comment period.

Adopted SIP Revisions

A SIP revision is made up of a narrative section, which is like a summary report, and typically will consist of various rules and agreements to legally fulfill what is written in the narrative.

Only one SIP exists for each state. For Texas, this document was initially approved in May 1972. Rather than rewriting the entire SIP each time changes are made, parts of the SIP are simply revised as needed.
