Crooked Creek WWTP # 2.
Please pay particular attention to the following permit conditions:
• Permit Condition 3 which requires that the wastewater collection facilities be properly
.operated and maintained in accordance with 15A NCAC 2H .0227 or any individual system-
wide collection system permit issued to the Permittee.

RE: Proposed manifolding of North Fork Crooked Creek and Crooked Creek WWTF
Influent Pump Station forcemaims
M&C#: 0771.0015 (10)
It is the intent of Union County Public Works to connect the existing Crooked Creek WWTF
influent force main and the existing North Fork Crooked Creek force main with a proposed 12-
inch force main. The 12-inch line will be manifolded with the existing 18-inch influent force
main at approximately twenty-five feet upstream from the plant's influent meter vault. McKim
& Creed has completed analysis of the force main manifolding and its impacts on the Crooked
Creek influent pump station.
A range of operating scenarios was considered. The minimal impacting scenario considered the
operation of any single pump in the station in addition to 100 gpm to 500 gpm of inflow from
the North Fork force main. The maximum impact scenario considered the simultaneous
operation of the five largest pumps in the lift station in addition to 100 to 500 gpm of inflow
from the North Fork force main.
McKim & Creed has determined that the influent lift station's pumps would experience an
additional 0.0082 to 0.0271 feet of friction head above their present operation condition. Due to
the small increases in head, the influent pumps will not experience arty readily apparent effects.
Union County can divert any amount of flow up to 500 gpm to the influent force main without
any adverse effects to the influent pump station.

Re: Permit Modification under Fast Track Application
Dear Mr. Gleason:
Union County Public Works would like to apply for a modification of existing permit No.
WQ0019570 dated June 08, 2001. The Crooked Creek Diversion Project Contract 4, 5 & 6 force
main conveys wastewater generated in the Crooked Creek basin to the Twelve Mile Creek basin
and ultimately to the Twelve Mile Creek WWTP, existing permit No. NC0085359. The Crooked
Creek diversion force main permit limit is 2.18 MGD.
The Twelve Mile Creek WWTP is currently at its allowable limit for flow acceptance and several
Union County projects including two (2) Public School projects within the plants service area
unable to obtain sewer permits. Union County would like to divert 0.5 MGD from the Crooked
Creek diversion force main to the Crooked Creek WWTP, existing permit No. NC0069841. The
resulting reduction in permitted flows to the Twelve Mile Creek WWTP could then be made
available to provide service to the projects currently requested. The Crooked Creek WWTP is
rated at 1.90 MGD with a current average day flow of 1.0 MGD (May 04 thru April 05). The
Crooked Creek plant can receive the additional 0.5 MGD and still retain 20% of its rated
capacity as reserve.
The diversion of flow to the Crooked Creek WWTP will be accomplished by the construction of
1538 feet of new 12-inch force main between the existing 16-inch Crooked Creek diversion force
main and the existing 16-inch plant influent force main. The existing 16-inch diversion force
main is routed along the road fronting the plant and crosses the plant entrance. The proposed
12-inch force main will be constructed along the plant access road from the entrance to a point
of connection with the existing influent force main located 25 feet upstream of the plant head
works. The 0.5 MGD blending rate will be accomplished by valve throttling in conjunction with
influent metering to determine the set point.

The County has engaged McKim and Creed to evaluate the effects of the interconnection of the
force mains on the existing influent pump station. Their findings indicate that this will cause no
detrimental effect to the current operations. A copy of their report is attached for reference.
We hope that the state will give consideration to our application. I can be reached at (704) 296-
4212 to answer any question that may arise.
