shown in plan and profile, and other information if pertinent or requested.
 5. For pump/lift stations and force mains, include all calculations and pump/performance curves.
 6. A check made payable to the State of Delaware for eight hundred twenty-five dollars ($825.00), the non-

corrections or changes made to address the Division’s comments. An additional eight hundred twenty-
five dollars ($825.00) non-refundable review fee must be submitted for resubmission of the plans if
changes are made to the project which trigger a complete review of the permit application.
Please submit the completed application package, as outlined above, to DE DNREC, Division of Water, SWDS,

The following items must be submitted prior to permit issuance:
 6. Verification from the appropriate county or municipal planning authority that the project has the proper
zoning approval.
 7. A letter from the owner/operator of the wastewater facilities to which the proposed collection and
conveyance facilities connect. The letter must include confirmation that the owner/operator has approved
the project, that the owner/operator will take responsibility for treating and disposing of the wastewater to
be conveyed and that the downstream facilities have the capacity to manage the additional flows without
causing or contributing to violations of Delaware’s Environmental Protection Act (7 Del. C., Chapter 60)
and the regulations promulgated thereafter. This includes, but is not limited to, unauthorized discharges
such as overflows at manholes and violations of the treatment system’s operating permit (for example, the
National Pollutant Discharge Elimination System (NPDES) permit).
