Water Street, Suite 6A, Dover, Delaware and 715 Grantham Lane, New Castle, Delaware.  To submit comments, for additional information or for an appointment to inspect the application, please contact Tracy Mattson at the Dover Office at 739‑9402.

The “draft/proposed” permit renewal is being submitted to EPA for concurrent processing.  If there are no significant comments, the “draft/proposed” permit renewal will be issued as a final permit after expiration of the EPA review period.

A public hearing concerning the permitting action will not be held unless the Secretary of the Department of Natural Resources and Environmental Control receives a request for such hearing within thirty (30) days from the date of this notice, ending September 23, 2019.  A request for a hearing shall be in writing and must show a familiarity with the application and a reasoned statement of the permit renewal’s probable impact.
