Subject: Issuance of NPDES Permit NCO067008
Old Cove Creek School WWTP
Watauga County
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 October 9, 2002.
The Division is currently in the process of implementing a Water Quality Standard for Total Residual Chlorine
(TRC) and expects to introduce permit limits statewide in April 2003. TRC is not currently limited in your permit, as
no disinfection is currently required. However, the Division may require disinfection in future renewals of this
permit. If you choose to use chlorine for disinfection, TRC will be limited between 17 µg/L and 28 jig/L.
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 (919)
733-5083, extension 511.

Annual Wastert,ater Treatment Plant Report
Cove Creek
NPDES #: NCO067008
Date: 2/11/02
We are pleased to present to you this year's Annual Wastewater Treatment Plant Report.
This report is designed to inform you about the quality of the wastewater we discharge to
the receiving waters every day. Our constant goal is to protect the environmental waters
of North Carolina. We want you to understand the efforts we make to continually
improve the wastewater treatment process and protect our water resources. We are
committed to ensuring the quality of the receiving waters that we discharge to.
If you have any questions about this report or concerning your wastewater utility, please
contact Morris Trammel at [phone]. We want our valued customers to be
informed about their. wastewater utility.
Let us first take this opportunity to give you a brief description of the Wastewater
Treatment Plant. The waters that go down the drain, follow many different pipes, and
ends up at the treatment plant. The wastewater goes through a bar screen that stops large
particles that are present (i.e., rags and papers). The water then goes to an aeration basin
where air is pumped into the water. This air supplies oxygen to bacteria that feed on the
solids that are in the water. The water then goes to the clarifier where the solids settle out.
The solids are pumped back to the aeration basin to give the bacteria a second chance to
feed. When there are too many solids in the plant, some of the solids are pumped to a
digester tank. In the digester, the bacteria have more time to feed on and reduce the solids'
volume*When the digester gets full, the solids are pumped from the tank and taken to a
larger facility. The clear water from the clarifier then goes to a tank for disinfection. The
two most prominent ways to disinfect the wastewater are chlorine and ultraviolet light.
Chlorine can be used as a gas or in solid tablet form. When chlorine is used, there is
generally a dechlorinating agent use to remove any excess chlorine from the wastewater
before it goes to the receiving water. When ultraviolet light (UV) is used, the wastewater
flows around the UV bulbs. Bacteria can not live when exposed to UV light, so as the
water passes the UV bulbs, the water in disinfected. Finally, after disinfection, the treated
wastewater goes into the receiving waters.
*Excess solids are taken to the Town of Boone Wastewater Treatment Plant.
