Question # 893

893. What is TRI.NET?
TRI.NET was EPA's desktop application that allowed users to create complex queries based on specific variables derived from the TRI National Analysis. TRI.NET was developed for analysts who require a highly interactive environment in order to refine queries and analyses. To build queries, users could select variables found in hierarchical folders that cover general variable counts, releases, waste transfers, waste quantities and hazard categories (a generated toxicity rating multiplied by chemical weight in pounds). After the user selected general variables, the application also allowed users to filter out variables, leaving only the most pertinent data points. TRI.NET utilized interactive features such as maps, My TRI Neighborhood, Drill Down, Advanced Trends, EPA Reports, and Data Layering; these features allowed users to further focus their interests. Raw data sets from the TRI National Analysis must be downloaded separately from the TRI.NET application; this can be done individually for each year or for a grouping of years. Each year that EPA releases a new data, the dataset will be available for download. TRI data and tools are available at
