Contains 8 excel spreadsheets about facilities of EPA offices. The state download data files contain facility data extracted from the Facility Registry System (FRS) in a format easy to import into a database or spreadsheet. The FRS is a centrally managed database developed by EPA's Office of Information Collection in the Office of Environmental Information (OEI). It provides Internet access to a single source of comprehensive information about facilities, sites or places subject to environmental regulations or of environmental interest. The FRS contains accurate and authoritative facility identification records which are subjected to rigorous verification and data management quality assurance procedures. The FRS has over 2.5 million unique facility records linking over 3.5 million program interests, including data from over 30 national environmental data systems and over 45 state systems.

The Substance Registry Services (SRS) is the authoritative resource for basic information about substances of interest to the U.S. EPA and its state and tribal partners. Substances, particularly chemicals, can have many valid synonyms. For example, toluene, methyl benzene, and phenyl methane, are commonly used names for the same chemical. EPA programs collect environmental data for this chemical using each of these names, plus others. This diversity leads to problems when a user is looking for programmatic data for toluene but is unaware that the data is stored under the synonym methyl benzene. For each substance, the SRS identifies the statutes, EPA programs, as well as organization external to EPA, that track or regulate that substance and the synonym used by that statute, EPA program or external organization. Besides standardized information for each chemical, such as the Chemical Abstracts Services name and the Chemical Abstracts Number and the EPA Registry Name (the EPA standard name), the SRS also includes additional information, such as molecular weight and molecular formula. Additionally, an SRS Internal Tracking Number uniquely identifies each substance, enabling cross-walking between synonyms. EPA is providing a large .ZIP file providing the SRS data in CSV format, and a separate small metadata file in XML containing the field names and definitions.
