Dear Mr. Myers:
Subsequent to Heater Utilities, Inc.'s adjudication of the subject NPDES permits originally released in
2005, and in accordance with the terms of the Settlement Agreement established between Heater
Utilities, Inc. and the Division of Water Quality to resolve matters in dispute within the terms of the
2005 permits, we are forwarding the attached NPDES discharge permits. These permits are 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).
These final permits include no changes from the draft permits sent to you on August 30, 2006.
Please be advised of the following conditions within these permits that are significantly different from
those found in the currently active permits:
• Where the existing permits had monthly average limits for ammonia nitrogen, daily maximum limits
for ammonia nitrogen have been added to those permits. These limits become applicable on the
effective date of the permits.
• For each of the permits, the fecal coliform monitoring frequency during the summer months has
been set at 3 days per week.
• For each of the permits, a new section titled "Operations" has been added. Within the section are
terms calling for 1.) the installation of turbidimeters to measure effluent turbidity, with the ability to
automatically communicate to the plant operator if a reading of 10 nephelometric units or higher is
detected; 2.) installation of SCADA systems, and 3.) daily inspection of the plants' disinfection
systems and documentation of those inspections.

• A condition has been added describing forms of public notification that must be made in the event of
a discharge of untreated or undertreated wastewater from the permitted facilities.
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.
It is expected that the issuance of these permits resolves all matters associated with the adjudication of
the 2005 permits and thereby, all pending action within the jurisdiction of the Office of Administrative
Hearings may be withdrawn.
If you have any questions concerning these permits, please contact Bob Sledge at telephone number
[phone], extension 547.
Sincerely,
