continued operation of a surface disposal site at the Fourth Creek wastewater treatment facility consisting
of a monofill with an area of approximately 9.4 acres, with trenches 80-100 feet long and 10 feet deep for
the disposal (by complete burial) of approximately 1,200 dry tons per year of residuals from the Fourth
Creek wastewater treatment facility, approximately 930 dry tons per year of residuals from the Third Creek
wastewater treatment facility and approximately 160 dry tons per year of residuals from the City of
Statesville water treatment facility with no discharge of wastes to the surface waters, pursuant to the
renewal request received on August 30, 1995, and in conformity with the project plan, specifications, and
other supporting data subsequently filed and approved by the Department of Environment, Health arty
Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until November 30, 2000, shall void Permit
No, WQ0001759 issued August 4, 1994, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
1. The sewage sludge units shall be effectively maintained and operated as a non -discharge
system to prevent the discharge of any wastes resulting from the operation of this program_
2. 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 program.
3. In the event that any sewage sludge unit is not operated satisfactorily, including the creation
of nuisance conditions, the Permittee shall cease disposing of the wastewater residuals to
the sewage sludge unit and take any immediate corrective actions as may be required by the
Division.

4. The following buffer zones shall be maintained:
a. 400 feet from any habitable residence,
b . 100 feet between an active sewage sludge unit and any public or private water supply
source, all streams classified as WS or B, waters classified as SA or SB and any Class
I or Class 11 impounded reservoir used as a source of drinking water,
c. 100 feet between an active sewage sludge unit and any stream, lake, river, or natural
drainage way,
d. 50 feet between an active sewage sludge unit and property lines (if the original permit
was issued with the buffer distance to property line as 100 feet, updated maps must be
submitted and new acreage delineated for the buffer to be reduced),
e. 10 feet between an active sewage sludge unit and any interceptor drains or surface
water diversions (upslope),
f. 25 feet between an active sewage sludge unit and any interceptor drains or surface
water diversions (downslope),
g. 25 feet between an active sewage sludge unit and any groundwater lowering and
surface drainage ditches.
Some of the buffers specified above may not have been included in previous permits for
this surface disposal site. These buffers are not intended to prohibit or prevent
modifications, which are required and approved by the Division, to improve performance
of the existing disposal facility. These buffers do apply, however, to any expansion or
modification of the surface disposal site, and apply in instances in which the sale of
property would cause any of the buffers now complied with, for the disposal facilities, to
be violated. The applicant is advised that any modifications to the existing facilities will
require a permit modification.
5. A copy of this permit shall be maintained at the surface disposal site when residuals are
being disposed during the life of this permit. A spill prevention and control plan shall be
maintained in all residuals transport and application vehicles.
6. Sewage sludge placed in a subject sewage sludge unit shall be covered with soil or other
material at the end of each operating day.
7. No residuals shall be stored on site at any time, unless approval has been requested and
obtained from the Division of Environmental Management.
Disposal (or any application) of residuals which test, or are classified, as hazardous or
toxic waste as defined in 40 CFR Part 261 is expressly prohibited at this site.
II. OPERATION' AND MAINTENANCE REQUIREMENTS

IV. GROUNDWATER REQUIREMENTS
The three (3) existing monitor wells (numbers 1, 2 and 3) shown on the attached site map,
must be sampled every March, July and November for the following parameters:
NO3
TDS
TOC
pH
Ammonia Nitrogen
Chloride
Water Level
Fecal Coliforms
Cadmium
Zinc
Copper
Volatile Organic Compounds
-In November only (by Method 1 or Method 2, below)

Method 1: Method 6230D (Capillary - Column), "Standard Methods For The
Examination of Water and Wastewater", 17th ed., 1989
Method 2: Method 502.2 "Methods For The Determination Of Organic Compounds
In Drinking Water", U.S. EPA-600/4-881039
The measurement of water levels must be made prior to sampling for the remaining
parameters. The depth to water in each well shall be measured from the surveyed point on
the top of the casing.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide the relative elevation of the measuring point for each monitoring well.
If TOC concentrations greater than 10 mg/1 are detected in any downgradient monitoring
well, additional sampling and analysis must be conducted to identify the individual
constituents comprising this TOC concentration. If the TOC concentration as measured in
the background monitor well exceeds 10 mg/l, this concentration will be taken to represent
the naturally occurring TOC concentration. Any exceedances of this naturally occurring
TOC concentration in the downgradient wells shall be subject to the additional sampling
and analysis as described above.
If any volatile organic compounds are detected by Method 6230D, or the equivalent Method
502.2, then the Mooresville Regional Office Groundwater Supervisor, telephone number
[phone], must be contacted immediately for further instructions regarding any
additional follow-up analyses required. The results of all initial and follow-up analyses
must be submitted simultaneously.
The results of the sampling and analysis shall be sent to the Groundwater Section, Permits
and Compliance Unit, P.Q. Box 29535 Raleigh, N.C. 27626-0535 on Form GW-59
[Compliance Monitoring Report Form] every April, August and December.
2. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is
for the disposal system constructed after December 31, 1983 is established at either (1) 250
feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is
closest to the waste disposal area. An exceedance of Groundwater Quality Standards at or
beyond the Compliance Boundary is subject to immediate remediation action in addition to
the penalty provisions applicable under General Statute 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the
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.
3. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided-
V. INSPECTIONS
i . The Permittee or his designee shall inspect the residuals storage, transport, and disposal
facilities to prevent malfunctions and deterioration, operator errors and discharges which
may cause or lead to the release of wastes to the environment, a threat to human health, or a
nuisance. The Permittee shall maintain an inspection log or summary including at least the
date and time of inspection, observations made, and any maintenance, repairs, or corrective
actions taken by the Permittee. This log of inspections shall be maintained by the Permittee
for a period of five years from the date of the inspection and shall be made available to the
Division of Environmental Management or other permitting authority, upon request.
