For questions, or to provide feedback to DNREC on the Initial Draft of the Regulations, please send an email to DNREC_USTRegulations@state.de.us or call Alex Rittberg at 302-395-2500. Information from prior meetings can be found below.
The Tank Management Section’s underground storage tank (UST) compliance program is responsible for ensuring the safe operation of over 400 federally regulated UST and 150 state regulated UST heating oil facilities in the state. UST systems which are subject to the requirements of the UST compliance program can be found at gas stations, manufacturing facilities, schools, and hospitals.
USTs over 110 gallons in size storing petroleum or hazardous substances are required to be registered with the state and pay an annual registration fee. Heating fuel (HF) UST systems greater than 1,100 gallons must be registered with the state. HF UST systems 1,100-2,000 gallons were required to pay an annual $50 fee until May 1993. HF UST systems over 2,000 must pay an annual $50 tank fee.
All registered USTs have to comply with Delaware Regulations Governing Underground Storage Tank Systems (UST Regulations) or (Printable Version). To assist owners and operators in complying with the UST Regulations the UST compliance program has created a Compliance Assistance Manual (CAM). The CAM contains easy to follow instructions and forms for UST system owners and operators.
The UST compliance program conducts inspections every three (3) years at facilities with UST systems to prevent releases to the environment by ensuring that UST systems are properly installed, inspected, tested, and maintained. The UST compliance program requires that facilities demonstrate financial responsibility for taking corrective action caused by accidental releases from the UST system.
The UST compliance program oversees the installation, retrofitting, and removal of UST systems to verify the work is completed properly and by qualified, trained, and certified individuals and companies. Facilities may have additional requirements for vapor recovery. This may require a tank owner to install specific equipment and follow scheduled equipment testing requirements.
Beginning August 8, 2012, each UST facility must have a certified operator assigned to the site. To become certified, an individual must attend an operator training class. For more information, please see the UST operator training webpage.
Information regarding UST facilities is available online using the Delaware Environmental Navigator (DEN). A request for information may be made through the Freedom of Information Act (FOIA).
