EPA Facility Registry Service (FRS): RBLC

Published by U.S. Environmental Protection Agency, Headquarters | U.S. Environmental Protection Agency | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-01-09T00:00:00.000+00:00
This web feature service contains location and facility identification information from EPA's Facility Registry Service (FRS) for the subset of facilities that link to the RACT/BACT/LAER Clearinghouse (RBLC). The RBLC database contains case-specific information on the air pollution technologies that have been required to reduce the emission of air pollutions from stationary sources. RACT, or Reasonably Available Control Technology, is required on existing sources in areas that are not meeting national ambient air quality standards. BACT, or Best Available Control Technology, is required on major new or modified sources in clean areas. LAER, or Lowest Achievable Emission Rate, is required on major new or modified sources in non-attainment areas. FRS identifies and geospatially locates facilities, sites or places subject to environmental regulations or of environmental interest. Using vigorous verification and data management procedures, FRS integrates facility data from EPA's national program systems, other federal agencies, and State and tribal master facility records and provides EPA with a centrally managed, single source of comprehensive and authoritative information on facilities. This data set contains the subset of FRS integrated facilities that link to RBLC facilities once the RBLC data has been integrated into the FRS database. Additional information on FRS is available at the EPA website https://www.epa.gov/enviro/facility-registry-service-frs.
