OVERVIEW OF TRI BASIC PLUS DATA FILES
The TRI "Basic Plus" data files include 10 file types that collectively contain all the data fields from the TRI
Reporting Form R and Form A (except Form R Schedule 1). The 10 file types are tab-delimited text (.txt) files
packaged into a .zip file.

Form R/Form A Reference

CA_lA_2017.txt
Facility data, chemical
identification, chemical uses, on-
site releases and management, off-
site transfers, summary information
Part 1 (all), Part II (section 1, 3,
4, 5, 6.1.A, 6.2ABC,
7B, 7C, 8.2.B, 8.4.B, 8.6.
The Basic Plus Data Files are identified (named) by state, file type, and reporting year:
File Name = State + File Type + Reporting Year
For example, the file "CA_lA_2017.txt" contains facility, chemical identification,
chemical use, on-site release and waste management, off-site transfer and summary information (File Type
1A) for all facilities located in California (CA) for reporting year 2017.
In addition to the set of data files for each state, there are two other Basic Plus file sets: Federal and National
The Federal files (FED_lA_2017.txt, FED_2A_2017.txt, etc.) contain TRI data for all government-owned-and-
operated federal sites. The National files (US_lA_2017.txt, US_2A_2017.txt, etc.) contain TRI data for all U.S.
states and territories for a specific year.

DESCRIPTION OF FILE TYPE IB CONTENTS
The "Type IB" file contains data about manufacturing (including importing), processing, and otherwise use
activities that occurred at the facility during the calendar year. Specifically, processing categories "as a
reactant" and "as a formulation component" now contain subcategories as do all otherwise use categories
(i.e., "as a chemical processing aid", "as a manufacturing aid," and "ancillary or other use").
All Type IB files contain data from the following parts and sections of the Form R:

Note: In 2005, the TRI Program stopped collecting underground injection control (UIC) identification numbers
from facilities on the TRI reporting forms. UIC IDs identify facilities that received permits from state
governments to dispose of or release chemical waste into Class I through Class V underground injection wells.
The TRI Program does have some historical UIC IDs that were collected prior to 2005. Many of these, however,
are outdated and inaccurate. The TRI Program is also missing UIC IDs for facilities that began reporting to TRI
in or after 2005. EPA does not store nor have access to current UIC IDs. Because of this lack of
current, accurate and complete data, the TRI Program removed the UIC ID data fields from the TRI Basic Data
Files in 2019.
To learn more about UIC permits and underground injection wells see the "Protecting Underground Source of
Drinking Water from Underground Injection (UIC)" website at https://www.epa.gov/uic

WHAT'S IN THIS DOCUMENT
The rest of this document is organized as a four-column data table. It describes what information you will
find when you download and open any of the TRI Basic Plus Data: File Type IB files.
Column
Description
Number (No.)
The sequential number of the data element in the record
Field Name
The name of the data element (Note: these names correspond to the various
column headings in the data files themselves.)
Data Type
'C' for character data (alphanumeric)
'N' for numeric data
'D'for date
Description
A brief statement of what the data element represents, plus its TRI System
Source (in Table Name. Field Name format) and where on the TRI Reporting
Form R the data element is reported (i.e., reference). TRI System Source refers
to the data element's physical location within EPA's Envirofacts online data
warehouse.
When you open any of the Basic Plus data files, you'll see that the contents are delimited by tabs,
meaning a tab is placed between each data element. The first row of each file contains column headers,
which correspond to the "field names" in this document.

are reported in pounds. Facilities cannot use range codes to report quantities for dioxin and dioxin-like
compounds and other Persistent Bioaccumulative Toxics (PBTs).
HELPFUL RESOURCES FOR USERS OF DOWNLOADABLE DATA FILES
When using any of the downloadable TRI data files, it will be helpful for users to refer to the TRI Reporting
Form R, the TRI Reporting Forms & Instructions document, and the Envirofacts TRI data model. The Reporting
Forms & Instructions document and sample reporting forms are available online in the GuideME application at
www.epa.gov/tri/euideme. The Envirofacts TRI data model is found at https://www.epa.gov/enviro/tri-model.
These resources provide useful context and have additional details about certain data elements.

APPENDIX B - NAICS Code Assignments
Until RY 2006, the TRI Program used Standard Industrial Codes (SIC) to identify each reporting facility's
industry sector. In RY 2006, the TRI Program began using North American Industry Classification System
(NAICS) codes.
To allow for analysis of data across years, the TRI Program assigned NAICS codes to each TRI submission from
1987 through 2005. The six methods used to assign NAICS codes and the number and percentages of
assignments per method are shown in the table below. The "Order of Precedence" column indicates the order
in which the methods were used to make an assignment.

Reported Data Used - In this method, the primary NAICS code reported by each facility in RY 2006 was used
to make an assignment to chemical submissions (Form Rs and Form As) for years 1987 to 2005. This method
was only used under the following conditions:
1.	The RY 2006 chemical submitted had only one primary NAICS code reported
2.	The prior year submission(s) for the same chemical had only one primary SIC code consistently
reported
3.	The SIC to NAICS Crosswalk (obtained for the U.S. Census Bureau) showed a one-to-one match
between the reported SIC and NAICS codes
This method was used to assign 50% of all NAICS codes.
SIC to NAICS Crosswalk - In this method, the TRI Program used a crosswalk or lookup table that translated SIC
codes into NAICS codes to assign a primary NAICS code to a pre-2006 TRI chemical submission. The primary SIC
code reported on the TRI form was used to lookup the corresponding NAICS code. Not all SIC codes translated
into only one NAICS code, so it was not possible to use this method to assign a NAICS code to each chemical
submission. However, it was used to make 29% of all the assignments.
EPA Facility Registry System (FRS) - In this method, the TRI Program used NAICS codes found in EPA's Facility
Registry System (FRS) to assign a primary NAICS code to each TRI chemical submission. This method was only

-------
used if FRS listed only one primary NAICS code for a facility. 11% of all assignments were made using this
method.
Commercial Sources - This method involved using various commercial services to verify NAICS code
assignments. 7% of all assignments were made using this method.
Statistics - For 3% of NAICS code assignments, the TRI Program used various statistical methods based on past
and present data.
Other Methods - Manual research (e.g., using Internet searches and other government agencies' data) and
personally contacting facilities helped the TRI Program assign NAICS codes to approximately 2,000 TRI
submissions.
