Dear Mr. Benton:
Please accept this letter as an official request for consistency determination on the enclosed
project. This project falls within the Areas of Environmental Concern (AECs) for Pasquotank
County, North Carolina.
The proposed project would install a generator with a 250 gallon diesel fuel tank to provide
emergency electrical power to sewage lift pumps located in Building 29. This building is the
main collection point for all wastewater generated on the facility. Wastewater collected at
Building 29 is pumped to the City of Elizabeth City Publically-Owned Treatment Works under
an locally issued wastewater permit. Presently, storage capacity at Building 29 is approximately
2 hours during peak flow periods and 5 hours during off-peak times. Infiltration from heavy
rains greatly affects wastewater storage capacity. The proximity of Building 29 to the
Pasquotank River and. the threat of overflow during an extended power outage provides
emphasis to the importance of this project.
Coast Guard Support Center Elizabeth City is a federal facility and is exempt from all CAMA
permit requirements under NCAC Title 15, Chapter 7, Section .0402.
If you have questions concerning this request, please contact CDR Mike Herring at (252) 335-
6356.
Sincerely,
r

Captain, U. S. Coast Guard

such as Uniform Fire Code (UFC) Articles 52, 79, Appendix IIF, Standard A-11-F-1 and th(
National :Fire Protection Association (NFPA Section 30 and 30A. These codes include
stringent performance requirements to ensure a tank design includes proper secondary

must be sure which UL label will be provided by the manufacturer.
