Control Technology Evaluation

Joshi Environmental provides client facilities with a process to evaluate and determine air pollution control requirements. In addition, we are available to provide an understanding of air pollution control requirements and processes that affect air permit applications.

Joshi Environmental provides assistance in completing case-by-case air pollution control technology reviews and describe control technology required by regulation or rule associated with the construction or modification of facilities (or emission units). A selection of control technology is contingent upon the location and the size of the project. One of the following control technology evaluations are generally required for a project:

• Best Available Control Technology (minor source and major source Prevention of Significant Deterioration [PSD])
• Lowest Achievable Emission Rate (LAER) (nonattainment major source)
• Reasonably Available Control Technology (RACT) (nonattainment source)
• Maximum Achievable Control Technology (MACT) (major sources of hazardous air pollutants)
• Generally Available Control Technology (GACT) (area sources of hazardous air pollutants)
