nuisance conditions, the Permittee shall take immediate corrective action, including those
as may be required by this Division, such as construction of additional or replacement
wastewater treatment or disposal facilities.
4. The issuance of this permit shall not relieve the Pere- ttee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
5. This permit shall become voidable if the soils fail to adequately absorb 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be rescinded unless the facilities are installed, maintained, and operated in a manner which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.
6. Adequate measures shall be taken to divert stormwater from the disposal area and prevent
wastewater runoff from the subsurface disposal field.
�.. , The sludge generated from these treatment facilities must be disposed of in accordance with
` General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.
8. A usable reserve area shall be maintained for wastewater disposal. The reserve area shall
have the capability of accommodating the average daily flow of the facility being served
without exceeding the loading rates of the reserve area while meeting all required buffer
requirements.

surface and ground water protection will be established and an acceptable sampling
reporting schedule shall be followed.
2. The nitrification lines shall be maintained as necessary (including purging of the lines) in
order to ensure that they remain free of obstructing materials. Adequate records showing
all maintenance shall be maintained by the Permittee.
3. A record shall be maintained of all residuals removed from this facility. This record shall
include the name of the hauler, permit authorizing the disposal or a letter from a
municipality agreeing to accept the residuals, date the residuals were hauled, and volume of
residuals removed.
4. Noncompliance Notification:
The Pennittee shall report by telephone to the Winston-Salem Regional Office, telephone
no. (919) 896-7007, as soon as possible, but in no case more than 24 hours or on the next
working day following the occurrence or first knowledge of the occurrence of any of the
following:
a. Any occurrence at the wastewater treatment facility which results in the treatment of
significant amounts of wastes which are abnormal in quantity or characteristic, such
as the dumping of the contents of a basin or tank; the known passage of a slug of
hazardous substance through the facility; or any other unusual circumstances.
b. Any process unit failure, due to known or unknown reasons, that render the facility
incapable of adequate wastewater treatment such as mechanical or electrical failures
of pumps, aerators, compressors, etc.
C. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
pass of all or any portion of the influent to such station or facility.
d. Any time that self -monitoring information indicates that the facility has gone out of
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 days following first knowledge of the occurrence. This report must outline
the actions taken or proposed to be taken to ensure that the problem does not recur.
IV. 'GROUNDWATER REQUIREMENTS
1. The permittee shall sample monitoring wells 1A, 2, 3, 4, R. Collins, H. Collins and

Water Level
The measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide relative elevations of the measuring point for each of the monitoring wells. The
depth of water in each well shall be measured from the surveyed point on the top of the
casing.
2. The influent and effluent of the treatment system shall be sampled every March, June,
September, and December for the parameters listed above.
3. If for some reason the treatment facilities fail to remove at least 95% of the contaminants,
then additional treatment technologies must be incorporated to increase the removal
efficiency to greater than 95%. The permittee shall also notify the Winston-Salem Regional
Office within 30 days when the removal efficiency is determined to be less than 95%.
4. The results of the sampling and analysis shall be sent to the N. C. Division of
Environmental Management of Form GW-59 (Compliance Monitoring Report Form) every
April, July, October and January.
5. The Compliance Boundary for the disposal system is specified by regulations in 15 NCAC
