Division of Water

Start Date: 5/19/2019

End Date: 6/18/2019

The Department of Natural Resources and Environmental Control, Division of Water, hereby gives notice that New Castle County Department of Special Services has applied for reissuance of its National Pollutant Discharge System (NPDES) Permit No. DE0050547 (State Number WPCC 3185G/75) to discharge treated wastewater from Middletown-Odessa-Townsend Regional Wastewater Treatment Plant located at 810 Old Corbit Road, Odessa, New Castle County, Delaware, to the Appoquinimink River. The treatment plant treats wastewater from domestic and commercial sources. Wastewater treatment is provided by drum screens, equalization tank, sequencing batch reactors, cloth filters and ultraviolet disinfection system. The waste sludge generated is transported to Wilmington Wastewater Treatment Plant for ultimate disposal. The biosolids generated during the course of treatment are aerobically digested and stored on-site in a lined lagoon equipped with surface aerators.

Based on a preliminary staff review and application of lawful standards and regulations, the Department proposes to re-issue this permit, subject to certain effluent limitations and conditions. The proposed determinations are tentative. Persons wishing to comment upon or object to the proposed determinations are invited to submit same in writing to the Surface Water Discharges Section of the Division of Water, at the address listed below, no later than 30 days from this notice. All comments received prior to said date will be considered in the formulation of final determinations regarding this application.

A public hearing on the above will NOT be held unless the Secretary of DNREC receives a request by 4:30 pm on June 18, 2019, or if the Secretary determines that a public hearing is in the public interest. A request for a hearing shall be in writing and shall state the nature of the issues to be raised at the hearing. It must also show familiarity with the proposal and a reasoned statement of the permit’s probable impact.

The applications, fact sheets, and permits are available for inspection or copies may be obtained by contacting:
