Dear LARRY ODELL:
Reference is made to your request for rescission of the subject NPDES Permit.
Staff of the Winston-Salem Regional Office have confirmed that this Permit is no longer
required. Therefore, in accordance with your request, NPDES Permit No. NCO038130 is
rescinded, effective immediately.
If in the future you wish to again discharge wastewater to the State's surface waters,
you must first apply for and receive a new NPDES Permit. Operating a facility without
a valid NPDES Permit will subject the responsible party to a civil penalty of up to
$10,000 per day.
If it would be helpful to discuss this matter further, I would suggest that you contact
the Water Quality staff, Winston-Salem Regional Office at [phone].

Subject: NPDES Permit Modification
Permit NCO038130
Northwest Junior and Senior High Schools
Guilford County
Dear Mr. Odell:
The Division is beginning the cycle of permit renewals for the Cape Fear river basin. An examination of the Cape
Fear basin plan and the NPDES permit schedule has revealed that the existing expiration dates in Cape Fear NPDES
permits do not coincide with the revised permit expiration dates for the basin. This discrepancy could create unnecessary
delays in the processing of over 200 permit renewals. Accordingly, the Division is changing the permit expiration dates for
NPDES permits in the Cape Fear river basin.
This permit modification changes the expiration date of the subject permit in subbasin 30602 to June 30, 2001. Please
find enclosed the revised permit cover page. Insert the new cover page into your permit and discard the old page. All
other terms and conditions contained in the original permit remain unchanged and in full effect. This permit modification
is issued under the requirements of North Carolina General Statutes 143-215.1 and the Memorandum of Agreement
between North Carolina and the U. S. Environmental Protection Agency.
In accordance with the modification of the permit expiration date, the new due date for your renewal application is
January 1, 2001. Renewal application forms will be sent to you approximately 6-8 weeks in advance of the new due date
or you may download the forms from the NPDES web site at http://h2o.enr.state.nc.us/NPDES/documents.html.
You will need to download Short Form D. If you have already submitted a permit renewal form, there is no need to
submit any other forms to the Division; the application will be processed during the renewal period for your subbasin.
If any part of this permit modification 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 a written petition conforming
to Chapter 150B of the North Carolina General Statutes, 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.
If you have any questions concerning this permit modification, please contact Natalie Sierra at [phone],
extension 551.

The permittee shall properly connect to an operational publicly owned wastewater collection
system within 180 days of its availability to the site, if the facility is in noncompliance with any
terms and conditions of the NPDES permit or governing rules, regulations and laws.
F. This permit may be modified, or revoked and reissued to include an effluent limitation on
nutrients for this discharge depending upon the following:
1. The findings of a study by the Division of Environmental Management determine nutrient
control is necessary.
2. Local actions do not successfully reduce the nutrient loading on the receiving waters.
3. The onset of problem conditions in the receiving waters.

recommended if a more environmentally sound alternative is available at an economically
reasonable cost. An engineering report evaluating alternatives to discharge is due 180 days prior to
permit expiration along with the permit renewal application. As part of the report, the cost of
constructing a treatment plant at the discharge point to meet limits of 5 mg/1 BODS, 2 mg/l NH3 as
N, 6.0 mg/1 DO, and 17.0 ug/1 chlorine should also be included if there are no feasible alternatives
to a surface discharge. Upon review of the results of the engineering report, the Division retains
the right to reopen and modify this NPDES permit to require removal of the discharge or to revise
the permit limitations within a specified time schedule.
