limitations:
I. PERFORMANCE STANDARDS
1. The sewage sludge unit 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 the 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. A copy of this permit shall be maintained at the sewage sludge 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.

5 . The following buffer zones shall be maintained:
a. 400 feet between the active sewage sludge unit and any habitable residence,

Some of the buffers specified above may not have been included in previous permits for
this sewage sludge unit. These buffers are not intended to prohibit or prevent
modifications, which are required by the Division, to improve performance of the existing
treatment facility. These buffers do, however, apply to. modifications of the surface
disposal site. These buffers do apply to any expansion or modification of the sewage
sludge unit and apply in instances in which the sale of property would cause any of the
buffers now complied with, for the treatment and disposal facilities, to be violated. The
applicant is advised that any modifications to the existing facilities will require a permit
modification.
6. Sewage sludge placed in the subject sewage sludge unit shall be covered with soil or other
material at the end of each operating day.

IV. GROUNDWATER REQUIREMENTS
The three (3) monitor wells, MW -1, MW -2, and MW -3, shall continue to be sampled every
March, July, and November, for the following parameters:
NO3
Ammonia Nitrogen
TDS
TOC
pH
Water Level
Chloride
Total Coliforms
Copper
Phenol
Lead
Zinc
SO4
Arsenic
Cadmium
Chromium
Iron
Volatile Organic Compounds - In November only (by Method 1 or 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/1, 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 Asheville 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.O. Box 29535 Raleigh, N.C. 27626-0535 on Form GW -59
[Compliance Monitoring Report Form] every April, August, and December.
2. Any groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
3. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary
for the disposal system constructed prior to December 31, 1983 is established at either (1)
500 feet from the waste disposal area, or (2) at 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).
5

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.
V. INSPECTIONS
1. 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.
2. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the surface disposal site or facility at any reasonable time
