Wastewater Rotary Distributor Facilities
Carteret County
Dear Mr. Crane:
In accordance with the renewal request received September 22, 1997, we are forwarding herewith
Permit No. WQ0007103, dated December 5, 1997, to the Sound of the Sea Master Association for the
continued operation of the subject wastewater rotary distributor facilities.
A review of the groundwater monitoring results for the subject facility indicate elevated levels of
Total Ammonia, Nitrate Nitrogen, Orthophosphate, Total Organic Carbon, and Fecal Coliforms in
monitoring wells MW-1, MW-2, and MW-3. In view of the existing monitor well locations, the historical
monitoring data, and the proximity of the nearby off -site municipal water supply well, the Groundwater
Section is requiring that the recently abandoned monitor well, MW-3, be replaced by a new monitor well,
MW-4. The elevated levels of several parameters in the upgradient area suggest that contamination could
be entering the site from a neighboring property, therefore, this situation will continue to be monitored.
Due to the fact that the rotary distributors are located in close proximity of the eastern property boundary,
the presence of individual septic systems on the properties abutting to the east, and the results of the
groundwater monitoring, the Groundwater Section is also requiring two new monitoring wells, MW-5 and
MW-6, be installed between the eastern property boundary and the rotary distributors. Please review
Permit Section IV Groundwater Requirements very carefully. If you have any questions regarding the
information pertaining to groundwater, please contact Mr. David Goodrich at [phone].
In addition to the above, the continuous flow monitoring device has indicated that additional flow
equalization may be needed. The existing pump station is currently being used as flow equalization,
providing approximately 5,000 gallons or 12.5% of the design flow. Current Division regulations require
a minimum of 25% flow equalization be provided. Due to the lack of flow equalization, hydraulic surges
could cause a portion of the effluent to bypass the teritary filters and be pumped directly to the rotary
distributors. This could lead to exceedances in groundwater levels. Additional flow equalization will
provide better operational controls and better treatment. The Division recommends the Sound of the Sea
Master Association consider constructing additional flow equalization.
This permit shall be effective from the date of issuance until October 31, 2002, shall void Permit
No. WQ0007103 issued July 8, 1993, 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.

permittee shall submit two original copies of a scaled topographic map (scale no greater
than 1 ".100') signed and sealed by a professional engineer or a state licensed land surveyor
that indicates all of the following information:
a. the location and identity of each monitoring well,
b. the location of the waste disposal system,
c. the location of all property boundaries,
d. the latitude and longitude of the established horizontal control monument,
e. the relative elevation of the top of the well casing (which shall be known as the
"measuring point"), and
f. the depth of water below the measuring point at the time the measuring point is
established.
The survey shall be conducted using approved practices outlined in North Carolina General
Statutes Chapter 89C and the North Carolina Administrative Code Title 21, Chapter 56.
The surveyor shall establish a horizontal control monument on the property of the waste
disposal system and determine the latitude and longitude of this horizontal control
monument to a horizontal positional accuracy of +/- 10 feet. All other features listed in a.
through e. above shall be surveyed relative to this horizontal control monument. The
positional accuracy of features listed in a. through e. above shall have a ratio of precision
not to exceed an error of closure of 1 foot per 10,000 feet of perimeter of the survey. Any
features located by the radial method will be located from a minimum of two points.
