Definitions for "Best Available Control Technology"
Technology required to reduce emissions of air pollutant. Defined in the Great Lakes Permitting Agreement as: "emission limits, operating stipulations, and/or technology requirements based on the maximum degree of reduction which each Great Lakes state determines is achievable through application of processes or available methods, systems, and techniques for the control of listed pollutants, taking into account energy, environmental, and economic impacts, and other costs."
An emission limitation based on the maximum degree of reduction of each air contaminant from stationary sources subject to regulation under the Clean Air Act of 1977 which the Air Pollution Control Officer, determines is achievable. This determination is made on a case by case basis, taking into account energy, environmental, and economic impacts and other costs for such stationary source through application of production processes and available methods, systems, and techniques for control of such air contaminants.
A concept taken from the Clean Air Act designed to preserve air quality from degradation by requiring that emissions from new facilities, temporary facilities, and even existing facilities in some instances be controlled to the extent possible using the best available technology.
