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 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.
M

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
Monitoring wells Nos. 12, 13, 14, 16, and 17 shall be sampled every March, July, and
November for the following parameters:
NO3
Ammonia Nitrogen
TDS (500.0)
SO4
Conductivity
Volatile Organic Compounds
pH (6.5-8.5 standard units)
TOC
Chloride (250.0)
Water Levels**
Sodium
*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 edition, 1989
Method 2: Method 502.2 " Methods for the Determination of Organic
Compounds in Drinking Water", United States Environmental
Protection Agency -600/488/039
** The measurement of water level must be made prior to sampling for the remaining
parameters.
For any other wells that Mallinckrodt continues to sample, those results should be
provided to the Division in accordance with the instructions below.
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 the 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.
5

If TQC concentrations greater than 10 mg/1 are detected in any downgradient
monitoring well, additional sampling and analysis must be conducted to identifv
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 EPA methods 604 and 611 must also be run to detect other
organic compounds which may be present. The results of all analysis 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)
by the last day of the month following the months in which sampling is required.
2. The Compliance Boundary 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 143-21.5.6(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 spray irrigation field, 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 BQLJNDARY 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.
3. No land application of waste activities shall be undertaken when the seasonal high water
table is less than three feet below the land surface.
4. Any additional groundwater quality monitoring, as deemed necessary by the Division,
shall be provided.

V. IN PECTI N
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 inspeot 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

the conditions of this permit, the approved plans, specifications, and other supporting
data.
2. This permit is effective only with respect to the nature and volume of wastes described in
the application and other supporting data.
3. This permit is not transferable. In the event there is a desire for the facilities to change
ownership, or there is a name change of the Permittee, a formal permit request must be
submitted to the Division of Environmental Management accompanied by an application
fee, documentation from the parties involved, and other supporting materials as may be
appropriate. The approval of this request will be considered on its merits and may or
may not be approved.

8. The annual administering and compliance fee must be paid by the Permittee within thirty
days after being billed by the Division. Failure to pay the fee accordingly may cause the
Division to initiate action to revoke this permit as specified by 15 NCAC 2H .0205
