The United States Environmental Protection Agency (EPA), in cooperation with the States, biennially collects information regarding the generation, management, and final disposition of hazardous wastes regulated under the Resource Conservation and Recovery Act of 1976 (RCRA), as amended. Collection, validation and verification of the Biennial Report (BR) data is the responsibility of RCRA authorized states and EPA regions. EPA does not modify the data reported by the states or regions. Any questions regarding the information reported for a RCRA handler should be directed to the state agency or region responsible for the BR data collection. BR data are collected every other year (odd-numbered years) and submitted in the following year. The BR data are used to support regulatory activities and provide basic statistics and trend of hazardous waste generation and management. BR data is available to the public through 3 mechanisms. 1. The RCRAInfo website includes data collected from 2001 to present-day (https://rcrainfo.epa.gov/rcrainfoweb/action/main-menu/view). Users of the RCRAInfo website can run queries and output reports for different data collection years at this site. All BR data collected from 2001 to present-day is stored in RCRAInfo, and is accessible through this website. 2. BR data files collected from 1999 - present day may be downloaded directory in zip file format from (https://rcrapublic.epa.gov/rcra-public-export/?outputType=Fixed or https://rcrapublic.epa.gov/rcra-public-export/?outputType=CSV). 3. Historical data collected prior to 1999 may be ordered on CD. Please see contact information in this metadata file to order historical BR data. BR data are typically published in December of the year following their collection. Data must be received by authorized states and EPA regions if a state is not authorized to implement the BR program by March 1st of the year following collection, and are usually published in December of the year following collection. For example, data collected in 2001 would be received by states and EPA regions by March 1, 2002 and states and EPA regions compile the BR data submitted by facilities and load the state data set into RCRAInfo, the system which EPA Headquarters (HQ) manage. Then EPA HQ published the data files around December 2002. Additional information regarding the biennial report data is available here: https://rcrapublic.epa.gov/rcra-public-export/rcrainfo_flat_file_documentation_v5.pdf and here: https://www.epa.gov/hwgenerators/biennial-hazardous-waste-report. Please note that the update frequency field for this data set indicates annual, but that the true update period is biennial (every other year). There is no selection option for biennial for the update frequency field.

Dataset Description: We know there are errors in the data although we strive to minimize them. Examples include: • Manifests completed incorrectly by the generator or the transporter - data was entered based on the incorrect information. We can only enter the information we receive. • Data entry errors – we now have QA/QC procedures in place to prevent or catch and fix a lot of these. • Historically there are multiple records of the same generator. Each variation in spelling in name or address generated a separate handler record. We have worked to minimize these but many remain. The good news is that as long as they all have the same EPA ID they will all show up in your search results. • Handlers provide erroneous data to obtain an EPA ID - data entry was based on erroneous information. Examples include incorrect or bogus addresses and names. There are also a lot of MISSPELLED NAMES AND ADDRESSES! • Missing manifests – Not every required manifest gets submitted to DEEP. Also, of the more than 100,000 paper manifests we receive each year, some were incorrectly handled and never entered. • Missing data – we know that the records for approximately 25 boxes of manifests, mostly prior to 1985 were lost from the database in the 1980’s. • Translation errors – the data has been migrated to newer data platforms numerous times, and each time there have been errors and data losses. • Wastes incorrectly entered – mostly due to complex names that were difficult to spell, or typos in quantities or units of measure. Since Summer 2019, scanned images of manifest hardcopies may be viewed at the DEEP Document Online Search Portal: https://filings.deep.ct.gov/DEEPDocumentSearchPortal/

This asset includes hazardous waste information, which is mostly contained in the Resource Conservation and Recovery Act Information (RCRAInfo) System, a national program management and inventory system addressing hazardous waste handlers. In general, all entities that generate, transport, treat, store, and dispose of hazardous waste are required to provide information about their activities to state environmental agencies. These agencies pass on that information to regional and national EPA offices. This regulation is governed by the Resource Conservation and Recovery Act (RCRA), as amended by the Hazardous and Solid Waste Amendments of 1984. RCRAInfo Search can be used to determine identification and location data for specific hazardous waste handlers and to find a wide range of information on treatment, storage, and disposal facilities regarding permit/closure status, compliance with Federal and State regulations, and cleanup activities. Categories of information in this asset include: -- Handlers -- Permit Information -- GIS information on facility location -- Financial Assurance -- Corrective Action -- Compliance Monitoring and Enforcement (CM&E)

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