The Delaware Sediment and Stormwater Regulations require an approved Sediment and Stormwater Management Plan from the department or a delegated agency for regulated land-disturbing activities.

Applicants will use either the Application for Detailed Plan Approval or an application for a standard Sediment and Stormwater Management Plan.

Standard Plans

The Regulations allow DNREC to develop criteria for cases when a standardized Sediment and Stormwater Management Plan may satisfy the requirement in the place of a detailed plan. When a project meets the Standard Plan applicability criteria for the project type, that project has the option to comply with the conditions of the Standard Plan for the project type, in lieu of developing a detailed Sediment and Stormwater Management Plan.

The forms listed here are for projects under the approval authority of DNREC’s Sediment and Stormwater Program. To apply for standard plan approval for projects to be reviewed by a delegated agency, contact that agency for the appropriate form.
