 Tank Management Section


The Division of Waste and Hazardous Substances' Tank Management Section (TMS) regulates the installation, operation, maintenance, and closure of Underground Storage Tank and Aboveground Storage Tank (UST and AST) systems in order to prevent contamination of soils and groundwater. The staff also permits the installation and operation of Vapor Recovery (VR) equipment, inspects Boilers and Pressure Vessels to protect public safety, and oversees the cleanup of releases from both UST and AST systems. The TMS prevents leaks to the environment by conducting inspections at regulated UST and AST facilities to ensure equipment is properly installed and maintained. These inspections take place at different types of facilities including gas stations, facilities that have large tank systems, and industrial or manufacturing sites located in Delaware. The TMS Program Manager is Alex Rittberg. He can be reached at 302-395-2500. The TMS office is located in DNREC's Lukens Drive Field Office building at: 391 Lukens Drive, New Castle, DE 19720 (Map & Driving Directions).

The Tank Management Section also oversees or conducts the investigation and clean up of petroleum and chemical contamination when spills and releases occur on properties with UST or AST systems. The TMS maintains and makes available upon request information stored in paper files and electronic databases relating to USTs, ASTs, and Boilers. Additionally, the TMS provides financial assistance through various programs for the removal of tanks and required cleanup. This includes managing the use of state funds dedicated to the removal and cleanup of UST systems where the owner cannot be found, refuses to perform the work, or does not have the ability to pay.

The Boiler Safety Program is also part of the TMS, ensuring public safety in all public and municipal buildings through inspections of boilers and pressure vessels and by providing education on the operation, maintenance, and repair of boilers and pressure vessels in the State of Delaware.

The TMS staff provides outreach and education by phone, newsletter, website, and presentations to specific groups regarding program activities and requirements.
