FRS Description

Facility Registry Service (FRS) is an EPA system used to take information from different program systems at the EPA and combine them into one database to enable information sharing and validate data inputs. FRS is integrated with the Central Data Exchange to power facility data validation and input. FRS is run by Office of Information Management (OIM).

FRS Data

FRS is made up of data from 90 systems inputting site data into FRS. Any source in the list FRS Data Sources is also called a "program system" which includes EPA program systems, (e.g., TRI), and state systems, (e.g., CARB-TCH).

Records in FRS are given an FRS ID, (also called Registry ID), that then have program records linked to the FRS ID. An FRS ID is in the format of (110012345678). For example, this FRS test record is FRS ID 110071730304 with a linked TSCA program record of TSCA10206722.

To see the last system data refresh data and then next scheduled refresh, see the  FRS data updates dashboard.

  • FRS Data Sources (Program systems: state, local, and tribal inputting data into FRS)
  • FRS Physical Data Model (Recommended for researchers)

EPA program systems act as the "source of truth" with data captured by the EPA. FRS then acts as a master data management system by adding data to each program system record input into FRS. An example of adding data, FRS completes the best pick process weekly to add a latitude and longitude for a new address. FRS applies an FRS ID (Registry ID) to the program record before the best pick process runs. The EPA has created multiple search tools and APIs to search this data.

Data Exchange

This is a legacy data flow called FacID for state and tribal systems to connect to FRS. For new connections to FRS our team recommends using the 2021 FRS API.
