Frequent Questions

What are critical errors, possible errors, and data quality alerts?

When validating TRI chemical forms in TRI-MEweb, users might receive critical errors, possible errors, or data quality alerts (DQAs).  What are the differences among critical errors, possible errors, and DQAs?

Critical errors, possible errors, and DQAs are all intended to show any errors that may exist on TRI forms.  Preparers should carefully review all errors and DQAs prior to submitting any forms to EPA.

Critical errors show information on a current year form that is incorrect or incomplete.  Users must correct any forms that have a validation status of "Failed with Critical Errors" before they are allowed to submit the forms to EPA and their state.

Possible errors are intended to highlight a potential problem on a current year form.  Users should review and correct possible errors, if applicable.  If users review the errors and determine that they are not applicable, they may proceed to submit the form.  Users may submit forms to EPA with a possible error.

DQAs inform facilities of possible reporting issues.  DQAs are offered to assist facilities in ensuring accurate and consistent reporting by comparing the data that facilities report on current year forms to data they have reported on prior year forms.  Users should review their chemical quantity data to ensure accuracy, but as with possible errors, users may submit forms to EPA with a data quality alert.

Error checks are available throughout the form completion process using the “Check for Errors” button at the bottom of each page.  A Validation report in PDF format is also available to Certifying Officials in the Check for Errors page to verify whether to proceed to submit the form to EPA.
