5. Noncompliance Notification:
The Permittee shall report by telephone to the Raleigh Regional Office,
telephone no. 919/ 733-2314, 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 sludge digester; 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.
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
recur.
IV. GROUNDWATER REQUIREMENTS
Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
2. The six (6) existing monitor wells must be sampled initially prior to waste
disposal operations and thereafter every April, August, and December for the
following parameters:
NO3 (10.0) Ammonia Nitrogen
TDS (500.0) TOC
pH (6.5-8.5 standard units) Water Level
Chloride (250.0) Total Coliforms (1/100m1)
Volatile Organic Compounds - In December 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 - 600/4-88/39
L!
If any volatile organic compounds are detected by method 6230D, 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 measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring points (top 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 the 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, as specified in 15 NCAC 2L
[Groundwater Classifications and Standards]. Unless otherwise noted, the
concentrations are given in parts per million.
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 back round 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.
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 May, September, and January.
3. The Compliance Boundary delineated on the attached site plan for the disposal system is
specified by regulations in 15 NCAC 2L, Classifications and Water Quality Standards
applicable to the groundwater of North Carolina. An exceedance of Groundwater
Quality Standards beyond the Compliance Boundary is subject to penalty provisions
applicable under General Statute 143-215.6(1)a. The sale of property, by the Permittee,
which is within or contiguous to the disposal system site may alter location of the
Compliance Boundary.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the perimeter of the waste disposal area, or 50
feet within the property boundary.
If the title to any property which may affect the location of the Compliance Boundary is
changed, the permittee shall notify the Division Director within 14 days. The Director
shall then establish a modified Compliance Boundary which will be done as a
modification to the Permit.
The REVIEW BOUNDARY for the disposal system is specified by regulations in 15
NCAC 2L, Groundwater Classifications and Standards. A REVIEW BOUNDARY
is established around disposal systems midway between the Compliance Boundary and
the perimeter of the waste disposal area. When the concentration of any substance
equals or exceeds the maximum allowable concentration of that substance at the
REVIEW BOUNDARY, as determined by monitoring, the permittee shall either (i)
demonstrate, through predictive calculations or modeling, that natural site conditions,
facility design and operational controls will prevent a violation of standards at the
Compliance Boundary; or, (ii) submit a plan for the alteration of existing site conditions,
5
facility design or operational controls that will prevent a violation of standards at the
Compliance Boundary, and implement that plan upon its approval by the Director.
4. The Lagoon/ pond liners (for the 5 -day and 50 -day minimum holding ponds) shall be
installed in accordance with one of the following:
The lagoon shall have a liner of natural material at least one (1) foot in thickness at all
locations with a hydraulic conductivity of no greater than 1 x 10-6 centimeters per
second when compacted. Following installation and inspection of the lagoon liner, and
prior to waste disposal operations, verification of the liner's compliance with hydraulic
conductivity and thickness specifications must be provided to the Division of
Environmental Management, Groundwater Section, by the project engineer.
The interior surfaces of the lagoon shall be completely lined with a 60 -mil thick liner.
Following installation and inspection of the lagoon liner, and prior to waste disposal
operations, certification of the liner's compliance with approved construction
specifications and the liner's integrity must be provided to the Division of Environmental
Management, Groundwater Section, by the project engineer.
The effluent storage lagoons shall not be excavated into bedrock.
6. No land application of waste activities shall be undertaken when the seasonal high water
table is less than three feet below land surface.
V. INSPECTIONS
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 Pemuttee 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.
