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.Fugitive Air Emissions Point Source Air Emissions Surface Water Discharges
