Best Available Control Technology is the technology required pursuant to § 165 on new major sources and major modification subject to PSD requirements (sources located in attainment areas), which reflect the best control in use taking into account costs. PSD, or Prevention of Significant Deterioration, is a program established under Title I of the Clean Air Act to preserve air quality in areas already meeting the National Ambient Air Quality Standards (NAAQS).

Best Available Control Technology. The most up-to-date methods, systems, techniques, and production processes available to achieve the greatest feasible emission reductions for given regulated pollutants and processes. BACT is a requirement of NSR (New Source Review) and PSD (Prevention of Significant Deterioration). BACT as used in federal law under PSD is defined as an emission limitation based on the maximum degree of emissions reductions allowable taking into account energy, environmental & economic impacts and other costs. [(CAA Section 169(3)]. The term BACT as used in state law means an emission limitation that will achieve the lowest achievable emission rates, which means the most stringent of either the most stringent emission limits contained in the SIP for the class or category of source, (unless it is demonstrated that one limitation is not achievable) or the most stringent emission limit achieved in practice by that class in category of source. "BACT" under state law is more stringent than federal BACT and is equivalent to federal LAER (lowest achievable emission rate) which applies to NSR permit actions.

Acronym for est vailable ontrol echnology. A standard for permitting of baghouse and dust collectors that takes into account the impact of energy and equipment costs in balance with environmental needs in new or retrofit applications

Best Available Control Technology. That pollution control method that is recognized as the one removing the greatest amount of air pollutants for a particular industry or process. Cost is considered in requiring BACT.

Best Available Control Technology (Clean Air Act) Type of control technology required for new sources of criteria pollutants under the Clean Air Act's Prevention of Significant Deterioration Program. BACT is defined as the "maximum degree of reduction..achievable," taking into account economic, energy, and environmental factors. See Also: CAA...................

Best Available Control Technology. An emission limitation based on the maximum degree of reduction which DEC determines is achievable taking in to account energy, environmental and economic impacts and other costs. CAA § 169(3).

Best Available Control Technology. 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.

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."

Best Available Control Technology. An emission limit based on the maximum degree of reduction for each pollutant regulated by the Clean Air Act. The permitting authority, taking into account energy, environmental and economic impacts determines what emission limits facilities should achieve in an attainment area on a case-by-case basis by considering production processes, available methods, systems, and techniques.

Best Available Control Technology - the basis for establishing emission limits for major existing sources of hazardous compounds. Source: US EPA

Best Available Control Technology (For "prevention of significant deterioration" (PSD) areas: any new source in such an area must meet a pollution control standard that aligns with the maximum degree of pollution reduction available. Set on a case-by-case basis, acounting for energy, environmental and other economic impacts and costs.)

Best Available Control Technology. Technology required on new major sources that are built in attainment areas and on major modifications to existing facilities in such areas. BACT is established on a caseby- case basis through a permitting process required under the Clean Air Act. Controls required as BACT can be, but are not necessarily, less stringent than Lowest Achievable Emission Rate (LAER).

Best available control technology. It is an emission limitation that considers the cost of energy, environment, and economics in developing a degree of emission reduction that is achievable through application of good production processes, control systems, and techniques. In no event can BACT allow emissions of a pollutant in excess of a NSPS or a NESHAPS. BACT is determined on a case-by-case basis, is applied to each pollutant regulated under the Clean Air Act (federal) and is used mostly in PSD permit work.

Best Available Control Technology. 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.

Best Available Control Technology. An emissions limitation, based on the maximum degree of air pollution reduction, that is achievable through certain production methods, after taking into account energy, economic, and environmental impacts and other costs.

Best Available Control Technology. An emission limitation based on using the most up-to-date methods, systems, techniques, and production processes available to achieve the greatest feasible reductions with the consideration of energy, environmental, and economic impacts. These limitations are determined on a case-by-case basis as part of the PSD program.

Best Available Control Technology. An emission limitation based on the maximum degree of emission reduction (considering energy, environmental, and economic impacts) achievable through application of production processes and available methods, systems, and techniques. BACT does not permit emissions in excess of those allowed under any applicable Clean Air Act provisions. Use of the BACT concept is allowable on a case-by-case basis for major new or modified emissions sources in attainment areas and applies to each regulated pollutant.

Best Available Control Technology. an emission limitation based on using the most up-to-date methods, systems, techniques, and production processes available to achieve the greatest feasible emission reductions. These are the most stringent requirements for new or modified sources and are determined on a case-by-case basis as part of New Source Review

Best Available Control Technology. For any specific source, the currently available technology producing the greatest reduction of air pollutant emissions, taking into account energy, environmental, economic, and other costs. The most stringent technology available for controlling emissions; major sources are required to use BACT, unless it can be demonstrated that it is not feasible for energy, environmental, or economic reasons.

An emission limitation based on the maximum degree of emission reduction achievable under Title 1 of the CAAA. EPA will establish BACT standards for serious, severe and extreme nonattainment areas.
