Through storage tank regulation, licensing, and enforcement, the Underground Storage Tank (UST) branch’s services protects human health and the environment from the adverse effects of petroleum, petroleum-related products and hazardous materials from USTs in the District of Columbia. This branch is organized into two programs: Underground Storage Tanks (UST) and Leaking Underground Storage Tanks (LUST).

Underground Storage Tanks- This program oversees the installation of new tanks, and the operation, maintenance, and closure of existing tanks.

  • Forms, Guidance, and Public Documents: These documents help regulated entities and individuals understand and comply with District law related to USTs.
  • Operator Training: UST operators in the District must take DDOE-approved training, which can be found here. Additionally, this link provides guidance for delivery training provider requirements and required training for Class A, B, and C Operators.
  • Certifying UST Contractors: Individuals and businesses that perform underground storage tank removal, installation, testing, closure, and related work must be certified by DDOE.

Leaking Underground Storage Tanks- This program manages the cleanup of areas impacted by leaking tanks, ensuring that risks to human health and the environment are reduced and eliminated.
