AEROMETRIC INFORMATION RETRIEVAL SYSTEM - AIRS FACILITY SUBSYSTEM
Aerometric Information Retrieval System (AIRS) is a computer-based repository of information about airborne pollution in the United States and various World Health Organization (WHO) member countries. AIRS is administered by the U.S. Environmental Protection Agency, and runs on the IBM mainframe computer system at the EPA National Computer Center in Research Triangle Park, North Carolina. AIRS contains all air quality, emissions, compliance, and enforcement information that the Office of Air Quality Planning and Standards (OAQPS) and state agencies need to carry out their respective programs for improving and maintaining air quality. Reporting capabilities allow states to access and use their data. It eliminates the need for individual states to maintain their own databases of air pollution information and to reformat or reorganize data for submission to the EPAs database. AIRS provides standard information requirements and information handling procedures, which enables OAQPS to compare and to use data from different states. AIRS Subsystems and Applications include the AIRS Facility Subsystem. AIRS Facility Subsystem (AFS) contains both emissions and compliance data on air pollution point sources regulated by the U.S. EPA and/or state and local air regulatory agencies. AFS contains data on industrial plants and their components: stacks, the points at which emissions are introduced into the atmosphere; points, the emission point or process within a plant that produces the pollutant emissions; and segments, which are components of the processes that produce emissions. Compliance data is maintained at the plant and point levels, tracking classification status, inspections, and compliance actions. AFS also includes data for management of operating permit applications and renewals.
