Note: Reporting year (RY) 2016 is the most recent TRI data available. Facilities reporting to TRI were required to submit their data to EPA by July 1 for the previous calendar year's activities.. TRI Explorer is using an updated data set (released to the public in March 2018). This dataset includes revisions for the years 1988 to 2016 processed by EPA, after the National Analysis Dataset was released. 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. 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 show only net off-site disposal or other releases, that is, off-site disposal or other releases transferred to other TRI facilities reporting such transfers as on-site disposal or other releases are not included to avoid double counting.

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.

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.

A decimal point, or "." denotes the following: if a decimal point is reported across an entire row, the facility submitted a Form A (i.e., the facility certified that its total annual reportable amount is less than 500 pounds, and does not manufacture, process, or otherwise use more than 1 million pounds); or if a decimal point is reported in a single column, 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).

The user selected list of chemicals applied in this report includes: MERCURY ,MERCURY COMPOUNDS
