FOR THE
continued operation of a surface disposal unit for groundwater monitoring purposes only. The surface disposal
unit, which was originally constructed in 1983, has been inactive since 1996, is no longer permitted to receive
residuals, and consists of eight areas comprising 9.4 acres total. Area No. 1 was utilized during 1983, Area No. 2
was utilized during 1984, Area No. 3 was utilized in 1985, Area No. 4 was utilized in 1985 and 1986, Area No. 5

1995 through 1996. All eight areas were filled in with trenches that were approximately 80 to 100 feet in length
and 10 feet in depth. All residuals disposed in the surface disposal unit were generated by the City of Statesville's
Fourth Creek Wastewater Treatment Plant (NPDES Permit No. NC0031836), Third Creek Wastewater Treatment
PIant (NPDES Permit No. NC0020591), as well as the Statesville Water Treatment Plant. The above -described
operational activities shall not result in a discharge of wastes to the surface waters; shall be pursuant to the

shall be in conformity with the project plans, specifications, and other supporting data subsequently filed and
approved by the Department of Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until September 30, 2005; shall void Permit No.

surface disposal unit. If runoff cannot be prevented, a collection system shall be installed with the
capacity to handle runoff from a 24-hour, 25-year storm event. All collected runoff shall be disposed
in a manner approved by the Division of Water Quality (Division).
Adequate provisions shall be taken to prevent wind erosion from conveying pollutants or residuals
from the surface disposal unit onto the adjacent property or into any surface waters.

the occurrence or first knowledge of the occurrence of any of the following:
a. Any occurrence with surface disposal activities that results in the disposal of significant amounts of
wastes that are abnormal in quantity or characteristic.
b. Any failure of the surface disposal activities resulting in a release of material to receiving waters.
c. Any time that self -monitoring information indicates that the surface disposal unit has gone out of
compliance with the conditions and limitations of this permit or the parameters on which the
system was designed.
d. Any process unit failure, due to known or unknown reasons, that renders the surface disposal unit
incapable of adequate residual treatment.
e. Any spillage or discharge from a vehicle or piping system transporting residuals to the surface
disposal unit.

IV. GROUNDWATER REQUIREMENTS
Existing groundwater monitoring wells MW-I, MW-2, and MW-3 shall be sampled every December
for the following parameters: -
Cadmium (Cd) pH
Copper (Cu) Total Dissolved Solids (TDS)
Chlorides Total Organic Carbon (TOC)
Fecal Coliform Water Level
Nitrate -Nitrogen (NO3-N)
Volatile Organic Compounds (VOCs), using one of the following methods:
(A) Standard Method 6230D (PQL at 0.5 pgg/L or less),
(B) Standard Method 62 1OD (PQL at 0.5 µg/L or less),
(C) EPA Method 8021 (Low Concentration, PQL at 0.5 µg/L or less),
(D) EPA Method 8260 (Low Concentration, PQL at 0.5 µg/L or less), or
(E) Another method with prior approval by the Groundwater Section Chief.
Any method used shall meet the following qualifications:
(1) The laboratory shall be Division certified to run any method used.
(2) The method used shall, at a minimum, include all the constituents listed in Table
VIII of Standard Method 6230D.

shall be submitted simultaneously.
If TOC concentrations greater than 10 milligrams per liter are detected in any downgradient
groundwater monitoring well, additional sampling and analysis shall be conducted to identify the
individual constituents comprising this TOC concentration. If the TOC concentration as measured in
the background groundwater monitoring well exceeds 10 milligrams per liter, this concentration shall
be taken to represent the naturally -occurring TOC concentration. Any exceedances of this naturally -
occurring TOC concentration in the downgradient groundwater monitoring well shall be subject to
additional sampling and analysis as described above.
