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

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_l_2017.txt" contains facility, chemical identification, chemical use, on-site release
and waste management, off-site transfer and summary information (File Type 1) 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_l_2017.txt, FED_2A_2017.txt, etc.) contain TRI data for all government-owned-and-
operated federal sites. The National files (US_l_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 4 CONTENTS
The "Type 4" file contains the basic facility identification information for all facilities that have ever reported
to the TRI Program. Most facilities submit several reporting forms each year, for many years. When the data
are collected at the TRI Data Processing Center, differences in facility identification information between
forms and across years are identified, researched and reconciled. File Type 4 contains this "reconciliation" of
all the facility identification data the TRI Program has collected from each facility during its TRI reporting
history.
You'll notice that some facility-level data element names (e.g., those related to the facility's name and
location) appear twice in this file, once as the data element name and once with "SUBMITTED" in front
of the name (e.g., FACILITY NAME and SUBMITTED FACILITY NAME). The data elements labeled
"SUBMITTED" display the data as they appeared on the most recent submission for the reporting year.
If the data element does not have "SUBMITTED" in front of the name, it displays the last value of any
submission for any reporting year. Consider the following example.
In RY 2012, a facility reported its TRI data under the name "ABC Company." The facility continued to
submit its TRI data as "ABC Company" for the next four years. In July 2017, after submitting its RY 2016
TRI reporting form, the facility sent in a revision for RY 2012 with the facility name of "XYZ
Manufacturing."

Following the facility's RY 2012 revision (submitted in July 2017), the TRI Program revises the 2012 Basic
Plus data file. In the RY 2012 file, the SUBMITTED FACILITY NAME (field #16 in File Type 4) is now "XYZ
Manufacturing" because is the most recent facility name that was reported for RY 2012. The
SUBMITTED FACILITY NAME for all the other years' Basic Plus files (2013-2016), however, would be
"ABC Company" because it is the most recent facility name for each of those reporting years.
Following the RY 2012 revision, the "current" FACILITY NAME (field #5 in File Type 4) in the RY 2012 file
is now "ABC Company" because it's the last facility name of ANY submission reported by the facility to
TRI for any year. It is the most current name TRI has on file for the facility.
The TRI Program defines or recognizes a facility as a physical location, and assigns it a TRI Facility ID
number, or "TRIFID" for short (see field #4 in the record layout below) for identification purposes.
Sometimes, a facility's address may change due to United States Postal Service updates, or there may be
variations in how the facility reports its address from year to year (e.g., "1 East Main St." vs "One E. Main
Street"). As EPA obtains more accurate latitude and longitude coordinates for facilities, those may
change, as EPA is always striving to obtain better data. But, in general, the location of the facility should

-------
remain constant. Some data elements that describe the facility will change from year to year; facilities
frequently change ownership, names and contact personnel. However, the TRIFID and location should
stay the same.
Some of the data that appear in this file are not a result of facility reconciliation. The "Title of the
Certifying Official," "Certifying Official's Name," "Entire Facility Ind," "Partial_Facility_lnd," "Federal
Facility Ind," "GOCO Facility Ind" and the SIC codes are all taken from the last active and valid form the
facility submitted. All other data are the result of the reconciliation process.
All Type 4 files contain data from the following parts and sections of the Form R:

APPENDIX A - 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.
