Note: Reporting year (RY) 2010 is the most 

recent TRI data available. Facilities reporting 

to TRI were required to submit RY 2010 data 

to EPA by July 1, 2011. TRI Explorer is using 

the 2010 National Analysis data set (released 

to the public in October 2011). This dataset 

includes revisions processed by EPA as of 

October 14, 2011 for the years 1988 to 

2010. Revisions submitted to EPA after this 

time are not reflected in TRI Explorer 

reports.

TRI data may also be obtained through EPA 

Envirofacts.
Users of TRI information should be aware 

that TRI data reflect releases and other 

waste management activities of chemicals, 

not whether (or to what degree) the public 

has been exposed to those chemicals. 

Release estimates alone are not sufficient to 

determine exposure or to calculate potential 

adverse effects on human health and the 

environment. TRI data, in conjunction with 

other information, can be used as a starting 

point in evaluating exposures that may result 

from releases and other waste management 

activities which involve toxic chemicals. The 

determination of potential risk depends 

upon many factors, including the toxicity of 

the chemical, the fate of the chemical, and 

the amount and duration of human or other 

exposure to the chemical after it is released.

Off-site disposal or other releases include 

transfers sent to other TRI Facilities that 

reported the amount as on-site disposal or 

other release because not all states and/or 

not all industry sectors are included in this 

report.

For purposes of analysis, data reported as 

Range Code A is calculated using a value of 5 

pounds, Range Code B is calculated using a 

value of 250 pounds and Range Code C is 

calculated using a value of 750 pounds.
The facility may have reported multiple 

NAICS codes to TRI in the current reporting 

year. See the facility profile report by clicking 

on the facility name to see a list of all NAICS 

codes submitted to TRI for the current 

reporting year.

Beginning with the 2006 reporting year, the 

industry classification code is the North 

American Industry Classification System 

(NAICS), which has replaced the 1997 US 

Standard Industrial Classification (SIC) code. 

The primary NAICS code as reported by the 

facility is now used for all analysis purposes 

for all reporting years 2006 and later. For 

reporting years prior to 2006, EPA has 

assigned a primary NAICS code based on the 

SIC codes as reported for those years for the 

purpose of analyzing trends.

Forms listing NAICS codes 221111, 221112, 

221113, 221119, 221121 or 221122 are 

included in this category. However, if the 

facility reported in a year prior to 1998 and 

the form has an industry code equivalent to 

a manufacturing NAICS code, then the form 

is included in the manufacturing industry 

category and not in this industry category for 

that year.
A decimal point, or "." denotes that the 

facility left that particular cell blank in its 

Form R submission (a zero in a cell denotes 

either that the facility reported "0" or "NA" 

in its Form R submission). "NA" in a cell 

denotes that the facility has submitted only 

Form A and thus the data for release, waste 

transfers or quantities of TRI chemicals in 

waste are not applicable. By submitting a 

Form A the facility has certified that its total 

annual reportable amount is less than 500 

pounds, and that the facility does not 

manufacture, process, or otherwise use 

more than 1 million pounds of the toxic 

chemical.
