On June 18, 2013, TCEQ approved proposal of the 2014 Five-Year Regional Haze State Implementation Plan Revision, which would provide a progress report on visibility protection at Class I federal areas (i.e., many national parks and wilderness areas) in Texas. 

Now that the proposal has been approved, the next steps involve federal and public comment periods and a public hearing. The progress report is scheduled to be adopted by TCEQ in February 2014.

More information is available on TCEQ's website.
