EPA regulates hazardous waste under the Resource Conservation and Recovery Act (RCRA) to ensure these wastes are managed in ways that protect human health and the environment. Generators of hazardous waste are regulated based on the amount of hazardous waste they generate in a calendar month, not the size of their business or facility. This data includes 5 categories of hazardous waste generators: LQG: Large Quantity Generators (LQGs), as part of EPA’s RCRAInfo system, generate 1,000 kilograms per month or more of hazardous waste or more than one kilogram per month of acutely hazardous waste. The data are extracted from RCRAInfo with the GENSTATUS flag that equals “LQG”. SQG: Small Quantity Generators (SQGs), as part of EPA’s RCRAInfo system, generate more than 100 kilograms, but less than 1,000 kilograms of hazardous waste per month. The data are extracted from RCRAInfo with the GENSTATUS flag that equals “SQG”. VSQG: Very Small Quantity Generators (VSQGs), as part of EPA’s RCRAInfo system, generate 100 kilograms or less per month of hazardous waste or one kilogram or less per month of acutely hazardous waste. The data are extracted from RCRAInfo with the GENSTATUS flag that equals “VSQG”. CEG: Conditionally Exempt Small Quantity Generators (CESQGs), as part of EPA’s RCRAInfo system, generate no more than 100 kilograms of hazardous waste per month. The data are extracted from RCRAInfo with the GENSTATUS flag that equals “CEG” (CEG is a standardized tag for CESQG in RCRAInfo database). TDSF: The Treatment, Storage, and Disposal Facilities (TSDF) are the generators of EPA’s RCRAInfo system that generate, treat, store, and dispose of hazardous waste. The data are extracted from RCRAInfo with the ACTIVE_SITE flag that contains “P”.

EF_RCRA is a subset of facilities from FRS_PROGRAM_FACILITY and associated best-available geospatial coordinates. Facility Registry Service (FRS) data are refrehsed daily. The layer shows only points from the RCRAInfo (Resource Conservation and Recovery Act Information) program.

The layer shows only points from the RCRAInfo (Resource Conservation and Recovery Act Information) program. The RCRA subset is updated weekly.

EF_BR is a subset of facilities from FRS_PROGRAM_FACILITY and associated best-available geospatial coordinates. Facility Registry Service (FRS) data are refrehsed daily. The layer shows only points from the 'BR' (Biennial Report) program. The program query is 'BR'. The BR subset is updated weekly.

EF_ICIS_AIR is a subset of facilities from FRS_PROGRAM_FACILITY and associated best-available geospatial coordinates. Facility Registry Service (FRS) data are refrehsed daily. The layer shows only points from the 'ICIS-AIR' (Integrated Compliance Information System for Air) program. The program query is 'AIR'. The ICIS-AIR subset is updated weekly.

Co-occurrence of natural hazard exposures and RCRA site locations at the county level where natural hazards are in the top quartile of exposures. This dataset is associated with the following publication: Summers, K., A. Lamper, and K. Buck. National Hazards Vulnerability and the Remediation, Restoration and Revitalization of Contaminated Sites – 2. RCRA Sites.. Sustainability. MDPI AG, Basel, SWITZERLAND, 13(2): 16, (2021).

This GIS dataset contains points which depict air quality monitors within EPA's Air Quality System (AQS) monitoring network. This dataset is updated weekly to reflect the most recent changes in the monitoring network. The monitors are generally operated by State, local, and tribal air pollution control agencies using procedures specified by the U.S. EPA. These agencies collect the data, quality assure it, and then submit it to the EPA Air Quality System (AQS). The GIS dataset includes monitor information and links to download historic air quality data at each monitor.
