Kinnakeet Shores
Wastewater Rotary Distributor Facilities
Dare County
In accordance with your application received June 24, 1996 we are forwarding herewith Permit
No. WQ0002284, dated October 17, 1996 to the Kinnakeet Shores Partnership for the construction and
operation of the subject wastewater rotary distribution facilities. The request for suspension of the
groundwater monitoring requirements, until the permitted capacity of the wastewater treatment facility has
been reached, has not been approved by the Division's Groundwater Section, however, the monitoring
requirements have been modified. The request was not approved based on the fact that the Groundwater
Section's 2L standards have been violated occasionally. The monitoring requirements have been modified
to require monitoring for fecal coliform instead of total coliform
This permit shall be effective from the date of issuance until September 30, 2001 shall void Permit
No. WQ0002284 issued January 23, 1992 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.
I€ 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.
