FRS Business Rules
The FRS retrieves key identifiers from program offices. Information includes facility name, address, city, etc. The FRS also ingests any geographic information, such as latitude and longitude. The program system id number is also retrieved and placed in the FRS database. FRS also stores the SIC and NAICS codes for facilities that are collected by the various program and state collections. FRS now offers a complete query result from either a SIC value or NAICS value. FRS further contains the Corporation Name which owns or operates the facility. The information from the various programs are then parsed to remove abbreviations and colloquialisms in order to be compared using a conservative matching algorithm. Matched ids are clustered under a single FRS id, while unmatched ids are given individual ids. Geographic information is stored in a separate Location Reference Table. FRS ids that lack a latitude and longitude are sent through EPA's geocoding process, which uses rooftop and map interpolation methods to derive a latitude and longitude with the appropriate method, accuracy and description (MAD) codes.
