shall include the name of the hauler, permit authorizing the disposal or a letter from a
municipality agreeing to accept the sludge, date the sludge was hauled, and volume
of sludge removed.
3. Noncompliance Notification:
The Permittee shall report by telephone to the Washington Regional Office,
telephone no. [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 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 reoccur.
IV. GROUNDWATER REQUIREMENTS
I . Oil drained from engine crankcases, antifreezes or degreasing solvents wastes shall
no be discharged into the disposal system.

2. Prior to beginning waste disposal operations, two (2) monitor wells shall be
constructed, one of which will be located between the disposed system and the
adjacent property boundary to the west. The well(s) shall be constructed such that
the water level in the well is never above or below the screened (open) portion of the
wells at any time during the year. However, the exact location and construction
details for these wells shall be approved by the Washington Regional Office, from
which a well construction permit must be obtained.
3. The monitor wells shall be sampled initially after construction (and prior to waste
disposal operations) and thereafter every January, April, July and October for the
following parameters:
NO3 (10.0)
TDS
pH (6.5 - 8.5 standard units)
Chloride (250.)
Ammonia Nitrogen
TOC
Water Level
Total Coliforms (1/104ml)
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 - 600/4-88/039
The measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring points (tops of well casing) of all monitoring wells shall
be surveyed relative to mean sea level (M.S. L.). The depth of water in each well
shall be measured from the surveyed point on top of the casing. The water level
elevations shall then be determined relative to M.S. L.
The numbers in parentheses represent the maximum allowable concentrations in
groundwater for the various analytical parameters in 15 NCAC 2L [Groundwater
Classifications and Standards]. Unless otherwise specified, the units for these
concentrations are expressed as milligrams per liter.
If TOC concentrations greater than 10 mg/l 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 623OD, or the equivalent
method 502.2, then EPA methods 604 and 611 must also be run to detect other
organic compounds which may be present. The results of all analyses specified in
the monitoring requirements, including 604 and 611 if required, must be submitted
simultaneously.
The results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management on Form GW -59 (Compliance Monitoring Report
Form] every February, May, August and November.

4. Any additional groundwater quality monitoring, as deemed necessary by the
Division, shall be provided.
V. INSPECTIONS,
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment 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 keep 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 three years from the
date of the inspection and shall be made available upon request to the Division of
Environmental Management or other permitting authority.
3. 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 disposal site and facility at any
reasonable time for the purpose of determining compliance with this permit; may
inspect or copy any records that must be kept under the terms and conditions of this
permit; or may obtain samples of groundwater, surface water, or leachate.
VI. GENERAL CONDITIONS
