The official name for BART is the Clean Air Visibility Rule (CAVR).
Definition
Best available retrofit technology is defined by USC ยง 7491:
in determining best available retrofit technology the State (or the Administrator in determining emission limitations which reflect such technology) shall take into consideration the costs of compliance, the energy and nonair quality environmental impacts of compliance, any existing pollution control technology in use at the source, the remaining useful life of the source, and the degree of improvement in visibility which may reasonably be anticipated to result from the use of such technology;
Navajo Generating Station
A BART rule may take into account the interests of stakeholders associated with the source. In the case of the BART review of the Navajo Generating Station in Page, Arizona near the Grand Canyon after the EPA issued a proposed BART rule it solicited input from stakeholders: the Department of the Interior, the Central Arizona Project, the Navajo Nation, the Gila River Indian Community, the Salt River Project, the Environmental Defense Fund, and Western Resources Advocates who as a technical working group negotiated a "Reasonable Progress Alternative to BART" which was submitted by the Department of the Interior to the EPA on July 26, 2013 for consideration in development of a final rule.
