AST Sampling Guidance

The Tank Management Section implements the Aboveground Storage Tank (AST) program. The AST program is responsible for ensuring the safe operation of over 1,000 regulated AST facilities in the state. All registered ASTs have to comply with Delaware’s Regulations Governing Aboveground Storage Tank Systems (AST Regulations).The AST program conducts inspections at facilities with AST systems to prevent releases to the environment by ensuring that AST systems are properly installed, inspected, tested, and maintained. The AST program also oversees the cleanup of sites which have had releases from AST systems. Information regarding AST system sites is available online using the Delaware Environmental Navigator (DEN). A request for information may be made through the Freedom of Information Act (FOIA).

UPDATE:  DNREC is in the process of revising the Proposed Amendments to the AST Regulations. A public hearing was held on December 6, 2016 at DNREC’s New Castle Office located at 391 Lukens Drive, New Castle, Delaware.  The initial public comment period on the Proposed Amendments closed on December 21, 2016. DNREC expects to have the revisions to the Proposed Amendments available for a second Public Comment from February 1 through March 3, 2017.   DNREC will provide a link to the Proposed Revisions as soon they become available for review in the State Register of Regulations. For more information on the proposed changes to the regulations, please visit the following links:

Invoices are sent to owners each year in December and include both AST Tank Registration and Vapor Recovery Operating Permit Fees. If you are an AST facility owner and have not received an invoice by the end of the calendar year, the Tank Management Section (TMS) should be notified.
Payments are due on or before February 1st of each calendar year. A 10% late fee per tank is assessed after that date. If a facility is sold or there is an owner billing address change, the TMS must be notified.
