Fran,
The RRO has recently been dealing with Chapel Hill West - Tower
Apartments. They have a discharge permit (NC0051331) which they used to
operate under. The facility was granted an "experimental' non -discharge
permit (WQ0013502), but due to the "experimental' nature, were required
as a condition of the non -discharge permit to retain their discharge
permit for one year. The non -discharge facility has been in operation
for a year, however, we have been unaware of this since we never
received an engineer's certification nor the proper monthly reports.
Due to the fact that we have. not seen a years worth of proper operation
and operational data, we are requiring that the discharge permit be
maintained until that is achieved. The owner, after some discussion,
has consented with this requirement, however, he said he has misplaced
his annual fee invoice. Would you please send him a new invoice. Thank
you.
-Tim Baldwin, RRO
In case the address is different, this is where he requested the invoice
be sent:

Subject: NPDES Permit Modification
Permit NCO051331
Tower Apartments
Chatham County
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 30604 to April 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
November 1, 2000. 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 facility discharges into a stream with 7Q10/30Q2=0 cfs. Removal of
discharge is 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/l
(130135,1 mg/1 NH3, 6 mg/1 DO, and 17A/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.

Facility is renewing at existing flow with no change in wastewater characteristics. Facility
discharges to stream with 7Q10/30Q2 = 0. Removal of discharge is recommended if a more
environmentally sound alternative is available at an economically reasonable cost. Facility must
submit an engineering report within 12 months of the effective date of this permit. As part of the
report, the cost of constructing a treatment plant at the discharge point to meet limits of 5 mg/I
BODS, 1 mg/I NH3, 6 mg/I DO, and 17 µg/I Chlorine should be included if there are no feasible
alternatives to a surface water discharge.

Parameter(s) Affected
x Parameter(s) are water quality limited. For some parameters, the available load capacity of
the immediate receiving water will be consumed. This may affect future water quality based
effluent limitations for additional dischargers within this portion of the watershed.
*
No parameters are water quality limited, but this discharge may affect future allocations.

INSTREAM MONITORING REQUIREMENTS
Upstream Location: UT to Meadow Branch approximately 59 upstream of discharge pipe
Downstream Location: UT to Meadow Branch approximately 50' downstream of discharge pipe
Parameters: Temperature, DO, Fecal, Conductivity

Facilities having a rating of one through four points, inclusive,
do not require a certified operator. Classification of all other
facilities requires a comparable grade operator in responsible
charge.
Facilities having an activated sludge process will be assigned
a minimum classification of Class II.
Facilities having treatment processes for the removal of metal
or cyanide will be assigned a minimum classification of Class IL
Facilities having treatment processes for the biological removal
of phosphorus will be assigned a minimum classification of Class
III.
In -plant processes and related control equipment which are an
integral part of industrial production shall not be considered waste
treatment. Likewise, discharges of wastewater from residences
having a design flow of 1.000 gpd or less, shall not be subject to
rating.
