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.

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_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.

Waste Treatment Method Codes
There are two lists of Waste Treatment Method Codes. The first list covers reporting years (RY) 2004 and prior. In RY
2005 many new Waste Treatment Method Codes were introduced. Many of the previous codes were retired (not used
anymore). The second list covers the new Waste Treatment Codes used in RY 2005 and after. Some of the older/retired
codes still appear in the TRI data after RY 2004. This is because some TRI data were still being submitted on paper
forms in and after RY 2005 (until 2013 As such, there was no automated software to prevent the codes from being
reported. The new Codes were adapted from RCRA Hazardous Waste Management Codes.

APPENDIX B - Range of Influent Concentration
From reporting year 1987 through 2004, the form R required an indication of the range of concentration
of the EPCRA section 313 chemical in the waste stream (i.e., the influent) as it typically enters the waste treatment step
or sequence. The concentration is based on the amount or mass of the EPCRA section 313 chemical in the waste stream
as compared to the total amount or mass of the waste stream. Facilities provided one of the following code numbers
corresponding to the concentration of the EPCRA section 313 chemical in the influent:
1 = Greater than 10,000 parts per million (1%)
2 = 100 parts per million (0.01%) to 10,000 parts per million (1%)
3 = 1 part per million (0.0001%) to 100 parts per million (0.01%)
4 = 1 part per billion to 1 part per million
5 = Less than 1 part per billion
Note: Parts per million (ppm) is:
milligrams/kilogram (mass/mass) for solids and liquids;
cubic centimeters/cubic meter (volume/volume) for gases;
milligrams/liter for solutions or dispersions of the chemical in water; and
milligrams of chemical/kilogram of air for particulates in air.
If particulate concentrations (at standard temperature and pressure) as grains/cubic foot of air, multiply by 1766.6 to
convert to parts per million; if in milligrams/cubic meter, multiply by 0.773 to obtain parts per million. These conversion
factors are for standard conditions of Oo C (32o F) and 760 mm Hg atmospheric pressure.
APPENDIX C - Waste Treatment Efficiency Range Codes:
El = greater than 99.9999%
E2 = greater than 99.99%, but less than or equal to 99.9999%
E3 = greater than 99%, but less than or equal to 99.99%
E4 = greater than 95%, but less than or equal to 99%
E5 = greater than 50%, but less than or equal to 95%
E6 = equal to or greater than 0%, but less than or equal to 50%

APPENDIX F - Dioxin and Dioxin-like Compound Data
In reporting year (RY) 2000, the Toxics Release Inventory Program began collecting congener data for dioxin
and dioxin-like compounds to better convey the relative toxicity of these chemicals being released or managed
at facilities. From RY 2000 through 2007, Part II, Section 1.4 of the Reporting Form R asked facilities to specify
the percentages of the 17 individual chemicals that make up a dioxin or dioxin-like compound for all media
(air, water and land). Fields #65-#83 of this file should contain those reported percentages.
In RY 2008, the TRI Program improved collection of dioxin and dioxin-like compounds data by introducing the
Form R Schedule One. This new supplemental form allows facilities to report quantities of each of the 17
dioxin congeners.
Although useful, total releases are not the best measure of the actual toxicity of dioxin and dioxin-like
compounds because each compound has its own level of toxicity. Both the original reporting of dioxin and
dioxin-like congeners and the Form R Schedule One reporting allowed the TRI Program to calculate Toxic
Equivalency (TEQ) values for each facility's dioxin releases. TEQs are a weighted quantity measure based on
the toxicity of each member of the dioxin and dioxin-like compounds category relative to the most toxic
members of the category. The values allow for comparison of the toxicity of different combinations of dioxins
and dioxin-like compounds, and help explain the relative toxicity of the TRI chemical release information.
For more information about dioxin and dioxin-like chemical reporting and the calculation of TEQs, see
https://www.epa.gov/toxics-release-inventorv-tri-program/dioxin-and-dioxin-compounds-toxic-equivalency-
information. To download dioxin data from the Form R Schedule One, visit https://www.epa.gov/toxics-

APPENDIX G - 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.
