Dear Mr. Cooperrider:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to
the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between
North Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as subsequently
amended).
This final permit includes no major changes from the draft permit sent to you on August
15, 2007.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings
(6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this
decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Quality or permits
required by the Division of Land Resources, the Coastal Area Management Act or any other Federal or Local
governmental permit that may be required. If you have any questions concerning this permit, please
contact Charles Weaver at telephone number [phone], extension 511.

Pre-SBR treatment system unknown.
pH will range from 6.5 to 8.5 as influent to the-SBR
The following design notes apply to the SBR System:
FLOW:
- Assume flow is received overa 24 hour period.
- A maximum daily hydraulic flow of 2.00 .times the average design has
been given.
Maximum daily flow has been interpreted as a flow condition which does
not represent an increased organic load.
PROCESS/SITE CONDITIONS:
-.An elevation of 1750 feet has been utilized.
DESIGN LOADINGS:
The aeration system has been designed to -provide oxygen for BOD at-1.25
lbs. 02/lb. BOD applied.
- TSS and TKN influent loadings have been assumed.
- The aeration system has been designed to provide oxygen for TKN at
4.60. lbs,. 02/lb. TKN applied:
ANTICIPATED PERFORMANCE:
The Following Design Notes Apply. -to -the Post-SBR---T-reatme-nt S-yetetv;
- Post SBR treatment unknown.
The Following Design Notes Apply -to the Sludge Holding .Basin:
Preliminary digester sizing yields a required volume of 20,364 gallons
in order to achieve,a 30 day sludge retention. time. (Basin by others)

Decant Flowrate = 80,000/(2 x 5 x 25) = 320 GPM
For gravity decanters 320 GPM would be the average flowrate.

Where:
ADF = average daily flow for decant (0.040 MGD) or
sludge waste (1;354 GPD)
DFR = design flow rate for decanter (320 GPM) or

Miscellaneous Comments
YESV This is a SIMPLE EXPEDITED permit renewal (administrative
renewal with no changes, or only minor changes such as TRC, NH3,
name/ownership changes). Include conventional WTPs in this group.
YES_ This is a MORE COMPLEX EXPEDITED permit renewal (includes
Special Conditions (such as EAA, Wastewater Management Plan), 303(d)
listed, toxicity testing, instream monitoring, compliance concerns, phased
limits). Basin Coordinator to make case -by -case decision.
YES_ This permit CANNOT RE EXPEDITED for one of the following reasons:
• Major Facility (municipal/industrial)
• Minor Municipals with pretreatment program
• Minor Industrials subject to Fed Effluent Guidelines (lb/day limits for BOD, TSS,
etc)
• Limits based on reasonable potential analysis (metals, GW remediation organics)
• Permitted flow > 0.5 MGD (requires full Fact Sheet)
• Permits determined by Basin Coordinator to be outside expedited process
