The 2018 TRI preliminary dataset consists of TRI data for 2018. Users should note that while these preliminary data have undergone the basic data quality checks included in the online TRI reporting software, they have not undergone the complete TRI data quality process. In addition, EPA does not aggregate or summarize these data, or offer any analysis or interpretation of them.
You can use the TRI preliminary dataset to:
Identify how many TRI facilities operate in a certain geographic area (for example, a ZIP code);
Identify which chemicals are being managed by TRI facilities and in what quantities; and
Find out if a particular facility initiated any pollution prevention activities in the most recent calendar year.
The agency will update the dataset several times in August and September based on information from facilities. EPA plans to publish the complete, quality-checked 2018 dataset in October 2019, followed by the 2018 TRI National Analysis in January 2020.
