Subpart A Additional Summary Information for this Facility or Supplier

Subpart A Validation Report

You can use the Validation Report to ensure the completeness and quality of your reporting data.

You should use the Validation Report to check your work. The Validation Report performs two types of checks:

  • Data Completeness: Data that are required for reporting is missing or incomplete.
  • Data Quality: Data are outside of the expected range of values.

You may view the Validation Report at any time.

Note that the Validation Report is intended to assist users in entering data, but it is not an indication that the reporter has entered all necessary information, nor is it an indication that the reporter is in compliance with 40 CFR Part 98. Furthermore a negative finding on the validation report is not a guarantee that a data element was entered incorrectly.
