An emission limitation which is not less stringent than the emission limitation achieved in practice by the best controlled similar source, and (MACT) which reflects the maximum degree of reduction in emissions that the permitting authority, taking into consideration the cost of achieving such emission reduction, and any non-air quality health and environmental impacts and energy requirements, determines is achievable by the source.
EPA standards mandated by the 1990 amendments to the federal Clean Air Act for the control of toxic emissions from various industries. Industries range from dry cleaners to petroleum refineries
Emissions limitations based on the best demonstrated control technology or practices. This is a very high level of pollution control.
Technology controls to be established for major sources of the 188 compounds listed as Hazardous Air Pollutants (HAPs). MACT must reflect the maximum degree of reduction available, taking into account costs and other factors.
Compare? Generally, the best available control technology, taking into account cost and technical feasibility.
(MACT) Emissions limitations based on the best demonstrated control technology or practices in similar sources to be applied to major sources emitting one or more of the listed toxic pollutants.
The maximum degree of reduction in emissions for new and existing air pollution sources, taking into consideration cost, non-air quality health and environmental impacts, and energy requirements.
