Air Data Systems
Air Facility System (AFS) is a sub-system of the Aerometric Information Retrieval System (AIRS). AFS contains compliance and permit data for stationary sources regulated by the U.S. EPA and state and local air pollution agencies. National Asbestos Registry System (NARS) was established by the U.S. Environmental Protection Agency in 1989 to store and track compliance information on owners and operators of asbestos demolition and renovation activities. All information in the system is stored and tracked by contractor name and city. Information is reported to NARS quarterly from State and Local environmental agencies and from U.S. EPA Regional Offices. Applicability Determinaton Index (ADI) is a database that contains memoranda issued by EPA on applicability and compliance issues associated with the New Source Performance Standards (NSPS), National Emissions Standards for Hazardous Air Pollutants (NESHAP) and chlorofluorocarbons (CFC).
