Case Studies for the 2024 Chemical Data Reporting; EPA CDR publication [June 29, 2023]

This document presents case studies to help you to report in 2024 for the Chemical Data Reporting (CDR) rule. EPA updated the 2020 case studies document to include updated screenshots from the reporting tool and reflect the reporting period covered by the 2024 submissions. The case studies also address general reporting issues from previous submission periods. These case studies are not based on actual data; they are hypothetical situations generated to assist submitters in completing the 2024 Form U.
