In accordance with the amendment request received September 29, 1997 from Jim Highley, Senior
Regional Manager with Carolina Water Service, Inc. of North Carolina, we are forwarding herewith
Permit No. WQ0009772, dated October 9, 1997, to Monteray Shores, Inc. and Ships Watch, Inc. (Buck
Island) for the continued operation of the subject wastewater rotary distributor facilities.
This permit is being amended as requested by the operator of the subject wastewater rotary
distributor facilities, Carolina Water Service, Inc. of North Carolina. This permit was previously amended
to allow the reuse of this water onto a proposed golf course. However, this project was abandoned and no
longer an available option. Therefore, this permit is being amended to reflect the limits typically given to a
wastewater rotary distributor facility, as outlined in Permit Condition 1112.
This permit shall be effective from the date of issuance until September 30, 1999, shall void Permit
No. WQ0009772 issued October 31, 1994, 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.

This permit shall be effective from the date of issuance until September 30, 1999, shall void Permit
No. WQ0009772 issued October 31, 1994, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
1. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective actions, including those
actions that may be required by the Division of Water Quality (Division), such as the
construction of additional or replacement wastewater treatment or disposal facilities.
2. This permit shall become voidable if the soils fail to adequately assimilate the wastes and
may be rescinded unless the facilities are installed,. maintained, and operated in a manner
which will protect the assigned water quality standards of the surface waters and ground
waters. The ponding of wastewater on the surface of the distribution field when the dosing
cycle commences shall be considered as evidence of failure of the soils to adequately
assimilate the wastewater. Additionally, such failure shall be interpreted as a violation of
this permit condition.

3. The residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the Division.
4. Adequate measures shall be taken to divert stormwater from the high rate infiltration area
and to prevent wastewater runoff.
5. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
6. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
7. The following buffers shall be maintained:
a) 400 feet between high rate infiltration unit and any habitable residence or place of public
assembly under separate ownership or which is to be sold,
b) 200 feet between high rate infiltration unit and any private or public water supply
source and any streams classified as WS or B,
c) 200 feet from mean high water between high rate infiltration unit and any "SA" or "SB"
classified surface waters,
d) 200 feet from normal high water between high rate infiltration unit and any other
stream, canal, marsh, or coastal waters,
e) 200 feet from normal high water between high rate infiltration unit and any Class I or
Class II impounded reservoir used as a source of drinking water,
f) 200 feet between high rate infiltration unit and any other lake or impoundment,
g) 200 feet between high rate infiltration unit and any Drainage systems (ditches, drains,
surface water diversions, etc.) and from any groundwater lowering and surface
drainage ditches,
h) 100 feet between high rate infiltration unit and property lines,
i) 50 feet between treatment units and property lines, and
j) 50 feet between high rate infiltration unit and other treatment units and public right of
ways.
Some of the buffers specified above may not have been included in previous permits for
this waste treatment and disposal system. These buffers are not intended to prohibit, or
prevent modifications, which are required by the Division, to improve performance of the
existing treatment facility. These buffers do, however, apply to modifications of the
treatment and disposal facilities which are for the purpose of increasing the flow that is
tributary to the facility. These buffers do apply to any expansion or modification of the
high rate infiltration areas and apply in instances in which the sale of property would cause
any of the buffers now complied with, for the treatment and disposal facilities, to be
violated. The applicant is advised that any modifications to the existing facilities will
require a permit modification.
8. A usable green area shall be maintained for wastewater disposal. The green area shall have
the capability of accommodating the average daily flow of the facility being served without
exceeding the loading rates of the green area. A "green area", as defined in 15A NCAC 2H
.0404 (g)(7), is an area suitable for waste disposal, either in its natural state or which has
been modified by planting a vegetative cover of grasses or low growing shrubbery.
It. OPERATION AND MAINTENANCE REQUIREMENTS

prevent the discharge of any wastewater outside of the high rate infiltration disposal area,
which result from the operation of this facility.
5. No traffic or equipment shall be allowed on the disposal area except while installation
occurs ,or while normal maintenance is being performed.
6. The rotary distribution fields shall be raked twice weekly during the months April through
October and once a week during the months of November through March.
7. The screenings removed from the wastewater treatment plant shall be properly disposed in
a sanitary landfill or by other means which have been approved by this Division.
8. Vegetative growth must be kept out of the rotary distribution areas at all times. All
vegetation must be removed manually so that minimal disturbance will occur to the disposal
area.
9. The application of chemicals to the distribution field(s) is expressly prohibited.
10. An automatically activated standby power source shall be on site and operational at all
times. If a generator is employed as an alternate power supply, it shall be tested weekly by
interrupting the primary power source.
