a. Any occurrence with the land application program which results in the
land application of significant amounts of wastes which are abnormal in
quantity or characteristic.
b. Any failure of the land application program resulting in a discharge of
wastes to receiving waters.
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 render
the facility incapable of adequate sludge treatment.
e. Any spillage or discharge from a vehicle or piping system transporting
sludge to the application site.
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.
1V. GROUNDWATER REQUIREMENTS
1. The four (4) existing monitor wells must be sampled every March, July, and
November for the following parameters:
NO3 (10.0)
TDS (500.0)
pH (6.5-8.5 standard units)
Chloride (250.0)
TOX (in November only)
Ammonia Nitrogen
TOC
Water Level
Total r'oliforms (1/100m1)
The measurement of water level must be made prior to sampling for the remaining
parameters.
The numbers in parentheses represent the maximum allowable concentrations in
groundwater for the various analytical parameters, as specified in 15 NCAC 21
[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/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.
The analytical methods used for TOX must be capable of detecting the total of all
X
halogenated organic compounds present at a concentration of 5.0 parts per billion
(ppb) or greater. In the event that a TOX concentration of 5.0 ppb or greater is
detected, any individual halogenated organic compound(s) present at a concentration
at or above the method detection limit (MDL) must be identified and quantified
utilizing EPA methods 601, 602, 604, and 611.
The results of the sampling and analysis shall be sent to the N.C. Division of
Form) every March, July, and November.
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 before December 30, 1983, the Compliance Boundary
is established at a distance 500 feet from the sludge application area , or the property
boundary, whichever is less.
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, 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.
Any additional groundwater quality monitoring, as deemed necessary by the
division, shall be provided.
V. INSPECTIONS
1. The Permittee or his designee shall inspect the sludge 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 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 by the
Division of Environmental Management or other permitting authority.
2. Any duly authorized officer, employee, or representative of the Division of
I
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.
