1 Sampled in November only
b. For Total Organic Carbon (TOC), if concentrations greater than 10 mg/l are detected in any
down -gradient monitoring well, additional sampling and analysis most 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 down -gradient wells shall
be subject to the additional sampling and analysis as described above.
c. For Volatile Organic Compounds (VOCs) sampled in November, use only one of the
following methods:
1) Standard Method 6230D, Practical Quantitation Limit (PQL) at 0.5 µg /L or less
2) Standard Method 6210, PQL at 0.5 gg/L or less
3) EPA Method 8021, Low Concentration, PQL at 0.5 µg /L or less
4) EPA Method 8260, Low Concentration, PQL at 0.5 µg /L or less
5) Another method with prior approval by the Aquifer Protection Section Chief.
Any of the referenced methods used for VOCs must at a minimum, include all the
constituents listed in Table VIII of Standard Method 6230D. Any method used must provide
a PQL of 0.5 µg IL or Iess, which must be supported by laboratory proficiency studies as
required by the DWQ Laboratory Certification Unit. Any constituents detected above the
Method Detection Limit (MDL) but below the PQL of 0.5 µg /L must be qualified
(estimated) and reported.

3. Reporting / Documentation:
a. All reports and documentation (GW-1, GW-30, GW-59) shall be mailed to the following
address:
Division of Water Quality
Information Processing Unit
1617 Mail Service Center
Raleigh, NC 27699-1636
Updated blank forms (GW-1, GW-30, GW-59) may be downloaded from the Groundwater
Section's website at http://Rw.ehnr.state.nc.us/ or requested from the address mentioned
above.
b. For the initial sampling of the well(s), the permittee shall submit a copy of the GW-I Form
(Well Construction Record) with the Compliance Monitoring Form (GW-59) for each well to
the address listed in the "Reporting / Documentation" section of the Groundwater
Requirements. Initial Compliance Monitoring Forms that do not include copies of the GW-1
form may be returned to the permittee without being processed. Failure to submit these
forms as required by this permit may result in the initiation of enforcement activities pursuant
to NC General Statutes 143-215.6A.
The results of the sampling and analysis must be received on Form GW-59 (Groundwater
Quality Monitoring: Compliance Report Form) by the Aquifer Protection Section (address
listed in the "Reporting / Documentation" section of the Groundwater Requirements), on or
before the last working day of the month following the sampling month. The data of all
groundwater sampling analyses required by the permit conditions must be reported using the
most recent GW-59 form along with attached copies of the laboratory analyses.
d. Within sixty (60) days of completion of [the / all) monitoring well(s), the permittee shall
submit two original copies of a scaled site map (scale no greater than V=100'); however,
special provisions may be granted upon prior approval for large properties. The map(s) must
include the following information:
1) The Iocation and identity of each monitoring well.
2) The location of major components of the waste disposal system.
3) The location of property boundaries within 500 feet of the disposal area(s).
4) The latitude and longitude of the established horizontal control monument.
5) The elevation of the top of the well casing (which shall be known as the "measuring
point") relative to a common datum.
6) The depth of water below the measuring point at the time the measuring point is
established.
7) The location of Review and Compliance boundaries.
S) The date the map is prepared and/or revised.
Control monuments shall be installed in such a manner and made of such materials that the
monument will not be destroyed due to activities that may take place on the property. Maps
and any supporting documentation shall be sent to the Aquifer Protection Section as
addressed in the "Reporting / Documentation" above.
The permittee is responsible for the geographic accuracy of any map submitted, however
produced.

4. Vertical Separation Requirements:
Waste application activities shall not occur when the vertical separation between depth of
application and the water table is at less than one (1) foot. Verification of the water table
elevation can be confirmed by water level readings obtained from the piezometers and monitor
well(s) near the site or auger boring(s), which must be done within 24 hours, prior to application
of wastewater. Any open borings must be properly filled with native soil, prior to application to
decrease the chance of any waste contaminating the groundwater.
5. Applicable Boundaries:
a. Arapahoe Spray Irrigation Site:
The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary
for the disposal system individually permitted after December 31, 1983 is established at
either 250 feet from the waste disposal area, or 50 feet within the property boundary,
whichever is closest to the waste disposal area. An exceedance of Groundwater Quality
Standards at or beyond the Compliance Boundary is subject to immediate remediation
action according to 15A NCAC 2L .0106(d)(2).
ii. The REVIEW BOUNDARY is established around the disposal systems midway between
the Compliance Boundary and the perimeter of the waste disposal area. Any exceedance
of standards at the Review Boundary shall require action in accordance with 15A NCAC
2L .0106(d)(1).
b. River Dunes Disposal Sites:
The COMPLIANCE BOUNDARY and REVIEW BOUNDARY for the waste disposal
area(s) is specified by regulations in 15A NCAC 2H, Waste Not Discharged to Surface
Waters, specifically .0219(k)(1)(C)(i)(III). The Compliance Boundary and the Review
Boundary for groundwater shall be established at the property boundary. An exceedance
of Groundwater Quality Standards at or beyond the Compliance Boundary is subject to
remediation action according to 15A NCAC 2L .0106(d)(2).
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 Perixrittee
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 or other permitting
authority.
3. Any duly authorized officer, employee, or representative of the Division may, upon presentation
of credentials, enter and inspect any property, premises or place on or related to the disposal site
or facility at any reasonable time for the purpose of determining compliance with this permit;
may inspect or copy any records that must be maintained under the terms and conditions of this
permit, and may obtain samples of groundwater, surface water, or leachate.

statutes, rules, regulations, or ordinances which may be imposed by other government agencies
(local, state, and federal) which have jurisdiction, including but not limited to applicable river
buffer rules in 15A NCAC 213.0200, erosion and sedimentation control requirements in 15A
NCAC Chapter 4 and under the Division's General Permit NCG010000, and any requirements
pertaining to wetlands under 15A NCAC 2B .0200 and 2H .0500.
6. The Permittee shall retain a set of approved plans and specifications for the subject facility for the
Iife of the project.
