Regional Haze SIP Consultation Meetings
The TCEQ held three Regional Haze SIP consultation meetings by conference call and invited participation from the following entities:
- Federal Land Manager for the Texas Class I areas at Big Bend and Guadalupe Mountains National Parks;
- Federal Land Managers in Class I areas of adjacent states, including staff of National Park Service, U.S. Fish and Wildlife Service, and U.S. Forest Service;
- Tribes in Texas and adjacent states;
- Other surrounding states that may impact Texas Class I areas; and
- U.S. Environmental Protection Agency.
The three consultation meetings from July 2007 have been summarized. The list of invited participants is provided. The purpose of the calls was to consult with state, federal, and tribal entities to further develop the Texas Regional Haze SIP. Through anouncements on the BART and SIP email notification system other interested parties such as the general public, environmental groups, and industry were invited to listen in to the conference calls and submit any comments and questions by e-mail.
