Underground Storage Tank Certification, Closures and Removals


UST Certifications Moved to IDEM in 2023

Effective July 1, 2023, IDHS no longer certifies UST workers, and all applications for new or renewed certification must be filed with the Indiana Department of Environmental Management (IDEM). However, any application filed with IDHS prior to the close of business on June 30, 2023, will be processed by IDHS, and all unexpired certifications issued by IDHS will remain in effect until expiration. After the close of business on June 30, 2023, the administration of the UST program was transferred from IDHS and all questions regarding this program should be directed to IDEM.
