| TRI Comparative Analysis Tool- Waste Data Sources |  |
This TRI Comparative Analysis tool allows users to compare records from the Toxics Release Inventory (TRI) with those from the Resource Conservation and Recovery Act Information system (RCRAInfo), which houses compliance and other information for facilities involved in the generation, handling, or treatment of hazardous waste. The TRI Comparative Analysis tool was originally developed to identify data quality problems in these data systems as well as potential compliance issues under the Resource Conservation and Recovery Act (RCRA) and the Emergency Planning and Community Right-to-Know Act programs.
Comparisons of data from TRI with data from RCRAInfo can be used to identify potential compliance and data quality problems. For example, TRI data from the most recent reporting year may be used to screen for potential noncompliance with Resource Conservation and Recovery Act (RCRA) reporting requirements. Under RCRA, a facility is designated as a Large Quantity Generator (LQG) if it generates more than 1,000 kg of hazardous waste in a given month, and as a Small Quantity Generator (SQG) or Conditionally-Exempt Small Quantity Generator (CESQG) if it generates less. Query 1 allows users to compare TRI facilities' reported waste shipments (not necessarily defined as hazardous waste) to their RCRAInfo facility designation to see if there are potential inconsistencies between TRI reporting and their RCRAInfo facility designation. TRI data can also be used to identify potential noncompliance with RCRA permitting requirements for treatment, storage and disposal facilities (TSDs). Query 2 allows users to examine the RCRA designation of TRI facilities reporting NAICS codes for hazardous waste management or solvent recovery. No regulatory requirements mandate that facilities other than TSDs that once handled hazardous waste notify that they have ceased waste management activities, or that the amount of waste they handle has changed. For example, some sites shown as LQGs may not be actively managing waste or may not meet the threshold to be considered an LQG. Although these queries present the universe in RCRAInfo as of the last ECHO data refresh, the states may have more current information. Links to state environmental agency web sites may be found in ECHO. Query 3 allows users to review TRI information associated with RCRAInfo records of facilities in TRI-reporting industries.
It is important to note that that the links between TRI and RCRAInfo records are based on name and address matching algorithms applied by EPA's Facility Registry System; there may be inaccuracies in linking facilities that are in these two data systems. Accordingly, users can verify the absence of corresponding records between TRI and RCRAInfo using the Facility Finder button 
. In those instances where a user finds a potential TRI-RCRAInfo match through Facility Finder that was not reflected in this tool's results report, the user is encouraged to use the "report error" feature on the relevant ECHO Detailed Facility Report to alert the Agency to the potential missing integration between the TRI and RCRAInfo databases.
The TRI Comparative Analysis tool is an ECHO partner site developed by the TRI Program in EPA's Office of Environmental Information. Questions and comments about this tool should be directed to ECHO Support.
