IV. GROUNDWATER REQUIREMENTS
1. Prior to beginning waste disposal operations at the new disposal fields, 5 new
monitor wells, shall be installed to monitor groundwater quality as designated on the
attached compliance boundary map. The wells shall be constructed such that the
water level in the well is never above or below the screened (open) portion of the
well at any time during the year. The location and construction details for these
wells must be approved by the Wilmington Regional Office, from which a well
construction permit must be obtained.
2. All monitor wells must be sampled initially after construction 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) Chloride (250.0)
Total Coliforms (1/100ml) Water Level (250.0)
Orthophosphate
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 "Method For The Determination Of Organic Compounds
In Drinldng 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 (top of well casing) of all new 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
mrouzndwater 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 background monitor well exceeds 10 mg/i, 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 analyses specified in
the monitoring requirements, including 604 and 611 if required, must be submitted
simultaneously.
C.
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 map 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, (new fields 1,2,3, and 4) the
Compliance Boundary is established at the lesser of 250 feet from the perimeter of
the subsurface disposal fields, or 50 feet within the property boundary.
For facilities permitted before December 30, 1983, (existing fields 2,3, and 4) the
Compliance Boundary is established at a distance 500 feet from the disposal fields,
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 delineated on the attached site map 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.
4. Monitoring wells designated to be abandoned shall be abandoned in accordance with
15A NCAC 2C (Well Construction Standards).
5. Line sinks (drainage ditches) shall be constructed on the northern and western
portions of the new disposal fields as recommended by Russnow, Kane and
Andrews.
6. Any additional groundwater quality monitoring, as deemed necessary by the
Division, shall be provided.
V. INSPE I N
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
7
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.
