MACT

Manufacturing Term

The MACT (Maximum Achievable Control Technology) is a regulatory standard used by the U.S. Environmental Protection Agency (EPA) to control air emissions from the industrial sector. It aims to reduce hazardous air pollutant (HAP) emissions by setting specific emission limits and requiring the use of the best available control technology (BACT) to achieve those limits.

In the manufacturing industry, MACT applies to a variety of processes, such as chemical manufacturing, pharmaceutical production, and metal fabrication. Facilities that emit HAPs above certain thresholds are required to comply with MACT standards.

To comply with MACT, manufacturers must first identify the HAPs produced by their processes. They must then determine the BACT that can be applied to reduce or eliminate those emissions. This involves evaluating various technologies, such as scrubbers, catalytic oxidizers, and other air pollution control devices.

Once a manufacturer has identified the appropriate BACT, they must implement it and maintain compliance by monitoring their emissions, conducting regular inspections, and submitting reports to the EPA. Failure to comply with MACT standards can result in fines, legal action, and reputational damage.

Overall, MACT plays an important role in protecting public health and the environment by reducing air pollution emissions from the manufacturing industry.
