Integon Life Insurance Corporation

Groundwater Remediation Facilities
Forsyth County
Dear Mr. Twombly:
In accordance with your modification request received December 21, 1994, we are forwarding
herewith Permit No. WQ0005286, dated February 20, 1995, to Integon Life Insurance Corporation for
the construction and operation of the subject groundwater remediation facility. This permit modification
consists of reducing the monitoring frequency for Water Level and Volatile Organic Compounds from
monthly to quarterly. Please be advised that the permit presently does not require monitoring of the
monitoring wells at the site. The Permittee should be advised that monitoring of the wells to delineate the
contaminant plume, could result in the elimination of the entire monitoring program, if the data confirms
that the plum has been remediated.
This permit shall void Permit No. WQ0005286 issued October 2, 1991 and shall be effective from
the date of issuance until August 31, 1996, 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, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. 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, P.O. Drawer
27447, Raleigh, NC 27611-7447. Unless such demands are made this permit shall be final and binding.
