2025 TDEC-DUST Virtual Tank School Compliance Proficiency Pre-Test

Tennessee Division of Underground Storage Tanks

TN Tank School is provided for our mutual continued efforts in achieving compliance with the Tennessee Division of Underground Storage Tank Rules and Regulations concerning the proper storage of petroleum in underground tank systems throughout the state.

Improved compliance is designed to prevent petroleum releases from occurring, as well as address and clean up releases quickly when releases do occur. Not only does compliance achieve environmental protection that makes Tennessee a better place to live, work and play, but also reduces costs by preventing loss of product, loss of worker time and potentially significant cleanup expenses.
