7. The application rate shall not exceed a cumulative loading of 23.92 inches over any
twelve (12) month period at an instantaneous application rate not to exceed 0.1 inches per
dose based on a 15 minute dosing period and a maximum loading of 0.46 inches per
week with an average of 5 to 8 applications per week.
8. 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.
9. No type of wastewater other than that from Highlands Cove shall be irrigated onto the
irrigation area.
10. All wastewater shall be routed to the five-day holding pond, should the limit for fecal
coliform (daily maximum concentration of 25 per 100 ml) or turbidity (instantaneous
maximum of 10 NTU) be exceeded, until such time that the problems associated with the
treatment capability of the wastewater treatment plant have been corrected. The
wastewater in the five-day holding pond shall be pumped back to the treatment plant for
retreatment or treated in the five-day pond prior to discharge to the storage pond.
11, Freeboard in the holding ponds shall not be less than two (2) feet at any time
12. Two (2) waste -level gauges, one to monitor waste levels in the 5 -day storage pond and
the other to monitor levels in the wet weather holding pond, shall be installed within 60
days of issuance of this permit. These gauges shall have readily visible permanent
markings indicating the maximum liquid level at the top of the temporary liquid storage
volume, minimum liquid level at the bottom of the temporary liquid storage volume, and
top of the dam elevations. Caution must be taken not to damage the integrity of the liners
when installing the gauges.
13. A protective vegetative cover shall be established and maintained on all earthen basin
embankments (outside toe of embankment to maximum pumping elevation), berms, pipe
runs, erosion control areas, and surface water diversions. Trees, shrubs, and other woody
vegetation shall not be allowed to grow on the earthen basin dikes or embankments.
Earthen basin embankment areas shall be kept mowed or otherwise controlled and
accessible.
14. The chlorine tablets used in the backup disinfection facility shall be of the kind and type
specified in the Division approved plans and specifications.
III. MONITORING AND REPORTING REOUIREMENTS
Any monitoring (including groundwater, surface water, soil or plant tissue analyses)
deemed necessary by the Division to insure surface and ground water protection will be
established and an acceptable sampling reporting schedule shall be followed.
2. Influent flow shall be continuously monitored and daily flow values shall be reported on
Form NDMR.

The Permittee shall install an appropriate flow measurement device consistent with
approved engineering and scientific practices to ensure the accuracy and reliability of
influent flow measurement. Flow measurement devices selected shall be capable of
measuring flows with a maximum deviation of less than 10 percent from true flow,
accurately calibrated at a minimum of once per year, and maintained to ensure that the
accuracy of the measurements is consistent with the accepted capability of that type of
device. The Permittee shall keep records of flow measurement device calibration on file
for a period of at least three years. At a minimum, data to be included in this
documentation shall be:
a. Date of flow measurement device calibration
b. Name of person performing calibration
C, Percent from true flow
3. As an indicator of proper operation and maintenance, the facility shall produce an
effluent in compliance with the following limitations:

collected during the reporting period.
C
Daily maximum shall be the maximum value of all samples collected during the
reporting period.
