Subject: Issuance of NPDES Permit NC0033421
College Park Subdivision WWTP
Gaston County
Dear Mr. Daniel:
In accordance with your application dated February 15, 1996. we are forwarding
herewith the subject State-NPDES 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 December 6, 1983.
In a letter dated July 22, 1996, Mr. Bruce Haas of your office requested two changes to
the draft permit. The Special Condition Part III, Item D is standard language for all permits, and
cannot be changed on a permit by permit basis. Thus, the language will remain the same.
Mr. Haas also requested modification to Item E of the Special Conditions. The change
recommended does not alter the intent and requirements of this condition in a significant way. It
is the Division's intent to permit the most environmentally sound alternative of the reasonably cost
effective options. Because of the close proximity of the subject facility to the town of Dallas'
sewer collection lines, the alternatives analysis is still required as stated in the permit.
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, Post Office Drawer 27447, Raleigh, North Carolina 27611-
7447. Unless such demand is made, this decision shall be final and binding. Please take notice
that this permit is not transferable. Part II, E.4. addresses the requirements to be followed in case
of change in ownership or control of this discharge.
This permit does not affect the legal requirement to obtain other permits which may be
required by the Division of Environmental Management or permits required by the Division of
Land Resources, 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
Susan Robson at telephone number 919/733-5083, ext. 551.
Sincerely,

PART _V - EVALUATION AND RECOMMENDATIONS
Carolina Water Service, Inc. , of N.C. is applying for renewal
of the permit to discharge treated domestic wastewater into Little
Long Creek.
A review of the past year' s self-monitoring data,
from 03/95
through 02/96, showed seven (7) daily maximum violations for Fecal
Coliform.
Carolina Water Services, Inc. , was requested to remove the
aeration system from the chlorine chamber. A condition in the
permit relative to this is suggested.
Pending receipt and approval of the Waste Load Allocation and
review and approval by P&E, it is recommended that the NPDES Permit
for this facility be renewed.
