The Department of Natural Resources and Environmental Control’s Division of Waste & Hazardous Substances reopened the public comment period and revised proposed amendments to Delaware’s Regulations Governing Aboveground Storage Tanks, as set forth in 7 DE Admin Code 1352.

The 30-day public comment period regarding the revised proposed amendments will be from Feb. 1 through DNREC close of business March 3.

The department revised the proposed amendments based on comments received prior to the Dec. 21, 2016, end of the initial public comment period. The revisions also correct formatting errors found in the original proposed amendments.

The purpose of the proposed regulatory action is to clarify technical requirements applicable to aboveground storage tank systems and specify applicable industry-based reference standards published by the American Petroleum Institute and other trade organizations. Additionally, the regulations propose minimum distances for locating new ASTs near private and public wells consistent with requirements set forth by DNREC’s well permitting regulations. Also, actions required in terms of both reporting and corrective action when AST releases occur have been updated to provide clarity and specificity.

The revised proposed regulations were published in the Feb. 1 edition of the Register of Regulations and may be viewed at

A public hearing on the initial draft of the proposed amendments was held Dec. 6, 2016. An additional public hearing will not be held on the revised proposed amendments unless the secretary of DNREC receives a request. Comments may be sent to or by mail to Lisa Vest, hearing officer, DNREC, 89 Kings Highway, Dover, DE 19901.
