Dear Mr. Clark:
In accordance with your application received July 19, 1994 we are forwarding herewith Permit
No. WQ0007798 as amended, dated November 30, 1994, to Toastmasters, Incorporated for the subject
groundwater remediation system. This permit amendment consists of the addition of carbon filters and the
approval for the treated effluent to be used as non -contact cooling water.
Please be advised of Condition 1. 1 which states that, "Upon completion of construction and prior
to operation of this permitted facility, a certification must be received from a professional engineer
certifying that the permitted facility has been installed in accordance with this permit and the approved
plans and specifications." To date, the Division has not received the Engineer's Certification for the
subject facility and therefore, this certification must include existing facilities as well as the additions.
Please be advised, failure to provide this certification in accordance with the conditions of this permit is a
violation and enforceable through the Environmental Management Commission.
This permit shall void Permit No. WQ0007798 issued on July 2, 1993 and shall be effective from
the date of issuance until June 30, 1998, and shall be subject to the conditions and limitations as specified
therein. Please pay particular attention to the monitoring requirements in this permit. Failure to establish an
adequate system for collecting and maintaining the required operational information will result in future
compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable to you, you have
the right to request an adjudicatory hearing upon written request within 30 days following receipt of this
permit. This request must be in the form of a written petition, conforming to Chapter 150B of North
Carolina General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer 27447,
Raleigh, NC 27611-7447. Unless such demands are made this permit shall be final and binding.

hazardous substance through the facility; or any other unusual circumstances.
b . Any process unit failure, due to known or unknown reasons, that render the facility
incapable of adequate wastewater treatment such as mechanical or electrical failures
of pumps, aerators, compressors, etc.
C. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
