DNREC Regulations


The regulations that govern the Department of Natural Resources and Environmental Control (DNREC) are published by the Office of the Registrar of Regulations as part of the Delaware Administrative Code.

Regulations Under Development

DNREC follows an internal regulatory development process to ensure that, to the extent possible, everyone who is interested in a proposed action regarding a regulation is properly notified about it, that the department follows a predictable and open process in developing, adopting, amending, and/or repealing such regulations, and that all these processes conform to legal and programmatic requirements.

All regulatory changes begin with an internal DNREC Start Action Notice (SAN) which lists the type and purpose of the proposed change, the statutory basis for the action, affected stakeholders, schedules and more information.  As part of the public review process, regulatory changes are published in the monthly Register of Regulations.
