NCDEO "r)W/NPDES
The City of Charlotte plans to construct a new fire station located at 3019 Beam Road, in the City of Charlotte,
Mecklenburg County, North Carolina.
The building's sewer service will carry to a point where it will join with existing sewer services from the
adjacent Charlotte Vehicle Operations Center, thereby creating a new public gravity sewer main. The existing
downstream 4-inch sewer service will be upsized to 6 inches and be classified as a main. The new private main
will continue downstream to a point where it will tie into an 8-inch public sewer, owned and maintained by
Charlotte Water.
The new 14,453 square foot fire station will house 11 on -site personnel in 3 shifts. Per 15A NCAC 02T .0114,
at 50 GPD/employee/shift, the fire station will generate 1,650 GPD of wastewater flow.
The existing facilities on the Charlotte Vehicle Operations Center do not meet any of the categories provided in
.0114 and so have been accounted for by assuming 250 GPD per plumbing fixture. These existing facilities are
already in use and the flow would already be accounted for in the downstream public sewer permit. We have
included these existing flows in the application simply to document that the gravity sewer has been
appropriately sized for the flows it will be carrying.
We are requesting a variance from NCAC 02T .0305 (i) — minimum 8 inch diameter pipe for public gravity
sewer. It is understood that the gravity sewer will be considered public by NCDEQ, but the limited flow
generated by the facilities in question does not warrant an 8-inch pipe. A 6-inch pipe is sufficiently sized for the
flows in question and will provide equal level of service as an 8-inch.
