This is the official final report prepared by the BRAVO Technical Subcommittee for the BRAVO Steering Committee.  EPA and NPS financed this study with contributions from EPRI, and staff of EPA, NPS, and the Texas Commission on Environmental Quality (TCEQ) comprised the Steering Committee. The BRAVO Study’s chief purpose was to quantify the contribution to haze at Big Bend National Park, Texas from source regions and source types in the U.S. and Mexico. This was a foundational, science-based study and not one that evaluated control strategy options. Detailed discussion of all analyses and procedures are available in the appendices and journal articles.<\/p>\n\n\n\n
