will protect the assigned water quality standards of the surface waters and ground waters.
2. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as
may be required by this Division, such as the construction of additional or replacement
treatment or disposal facilities.
3. 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.
4. Any 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

reporting schedule shall be followed.
2. Noncompliance Notification:
The Permittee shall report by telephone to the Mooresville Regional Office, telephone
number [phone], 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 -directly to receiving waters without treatment of all or any portion of the
influent to such station or facility.
d. Any time that self -monitoring information indicates that the facility is not in
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.
R UNDWATER REOUIREMENT
1. The Permittee shall monitor the volume of water recovered by each well by installing
appropriate flow meters on each well. The Permittee shall also monitor the water level of
the infiltration gallery. Measurements of flow and water levels shall be made weekly and
submitted monthly to the Mooresville Regional Office, Groundwater Supervisor for the
first 6 months of operation.
2. The groundwater recovery, treatment, and disposal system shall operate in a closed loop
manner as defined by G. S. 143-215.1A (a).

NOTE: Bedrock well MW-7 replaces MW-11 in the original permit, Bedrock well MW-8
replaces MW-12 in the original permit, and Bedrock well MW-9 replaces MW-13 in the
original permit. Also, the sampling frequency of the Bedrock wells has been changed from
Semi -Annually (in the original permit) to Quarterly.
4. The parameters to be monitored pursuant to the above schedule are:
EPA Method 602 ( including Xylenes, MTBE, Isopropyl Ether and EDB)
pH Water Levels

5. The influent and effluent of the treatment system shall be sampled bi-monthly for the
parameters listed in No. 4 above.
6. Isoconcentrations maps in both the vertical and horizontal directions shall be developed
using the groundwater monitoring data for BTEX, MTBE and NO3.
A water level contour map must also be developed. All maps should be developed on a
semiannual basis and should be submitted along with the groundwater monitoring data.

7. Two copies of the results of all sampling and analysis shall be submitted to the

property boundary, whichever is closest to the waste disposal area. An exceedance of
Groundwater Quality Standards beyond the Compliance Boundary is subject to the penalty
provisions applicable under General StatuW143-215.6(1)a.
Also in accordance with 15A NCAC 2L, a REVIEW BOUNDARY delineated on the
attached site map is established around disposal systems midway between the Compliance
Boundary and the perimeter of the waste disposal area. Any exceedance of standards at the
Review Boundary shall require remediation action on the part of the Permittee.
10. Any additional groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
11. All components of the groundwater recovery, treatment and disposal system shall be
properly weather -proofed to prevent freezing and failure of the system.

Other than Water Supply) and any other state and local laws and regulations pertaining to
well construction.
14. Within sixty (60) days of completion of all monitoring wells, the 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 registered land surveyor that indicates all of the
following information:
a. the location and identity of each monitoring well,

well. Compliance Monitoring Forms that do not include copies of the GW-1 form will be
returned to the Permittee without being processed. Failure to submit these forms as
