A New Source Review (NSR) is a permitting process created by the US Congress in 1977 as part of a series of amendments to the Clean Air Act.The NSR process requires industry to undergo an Environmental Protection Agency pre-construction review for environmental controls if they propose either building new facilities or any modifications to existing facilities that would create a "significant ...
New Source Performance Standards (NSPS) are pollution control standards issued by the United States Environmental Protection Agency (EPA). The term is used in the Clean Air Act Extension of 1970 (CAA) to refer to air pollution emission standards, and in the Clean Water Act (CWA) referring to standards for water pollution discharges of industrial wastewater to surface waters.
The PSD is part of the New Source Review program and was added to the CAA in 1977 with the goal of not allowing the good air to deteriorate, since it is only required for areas of attainment. [7] The PSD is focused on air quality in the region, in regards to health effects, as opposed to the emission technology.
The PSD provision requires SIPs to preserve good quality air in addition to cleaning up bad air. The new law also required New Source Review (investigations of proposed construction of new polluting facilities) to examine whether PSD requirements would be met. [51]
The Lowest achievable emissions rate (LAER) is used by the EPA to determine if emissions from a new or modified major stationary source are acceptable under SIP guidelines. LAER standards are required when a new stationary source is located in a non-attainment air-quality region. It is the most stringent air pollution standard above the best ...
For each listed source category, EPA indicates whether the sources are considered to be major sources or area sources. The 1990 Clean Air Act Amendments direct EPA to set standards for all major sources of air toxics, and for some area sources that are of particular concern. EPA is required to review all source category regulations every eight ...
For example, the United States Clean Air Act contains several control technology requirements, including Best Available Control Technology (BACT) (used in New Source Review), Reasonably Available Control Technology (RACT) (existing sources), Lowest Achievable Emissions Rate (LAER) (used for major new sources in non-attainment areas), and ...
The Air Permits Division processes air permits and authorizations for facilities that, when operational, would emit contaminants into the atmosphere. The division does this through two major air-permitting programs, New Source Review permits and Title V federal operating permits.
