Groundwater Monitoring; Requirements
24. The three existing monitoring wells,W-101, W-1-2 and W-103 shall be sampled every March, July and
November for the following parameters.
Water Level pH
Iron Total Dissolved Solids (TDS)
Manganese Total Organic Carbon (TOC)
Nitrate (NO3 as N) Chloride
Cadmium
Volatile Organic Compounds - In November only using one of the following:
(A) Standard Method 6230D, PQL at 0.5 ug/L or less
(B) Standard Method 621 OD, PQL at 0.5 ug/L or less
(C) EPA Method 8021, Low Concentration, PQL at 0.5 ug/L or less
(D) EPA Method 8260, Low Concentration, PQL at 0.5 ug/L or less
(E) Another :method with prior approval by the Groundwater Section Chief
Any method used must meet the following qualifications:
(1) A laboratory must be DWQ certified to run any method used.
(2) The method used must, at a minimum, include all the constituents listed in Table VIII of
Standard Method 6230D.
(3) The method used must provided a PQL at 0,5 ug/L or less which must be supported by
laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any
constituents detected above the MDL but below the PQL at 0.5 ug/L must be qualified
(estimated) and reported.
if any volatile organic compounds are detected by the methods listed, then the Winston-Salem Regional
Office Groundwater Supervisor, telephone number 336-771-4600, must be contacted immediately for
further instructions regarding any additional follow-up analyses required. The results of all initial and
follow-up analyses must be submitted simultaneously.
The measurement of water levels must be made prior to sampling for the remaining parameters. The
depth to water in each well shall be measured from the surveyed point on the top of the casing.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative
elevation of the measuring point for each monitoring well.
If TOC concentrations greater than 10 mg/I 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 ntg/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 must be received on Form GW-59 (Groundwater Quality
Monitoring: Compliance Report Form) by the Groundwater Section, Permits and Compliance Unit, P.O.
Box 29578 Raleigh, N.C. 27626-0578 on or before the last working day of the month following the
sampling month.
25. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be provided,

26. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A NCAC 2L,
Groundwater Classifications and Standards. The Compliance Boundary is for the disposal system
constructed after December 31, 1983 is established at either (1) 250 feet from the waste disposal area, or
(2) 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 in addition to the penalty provisions applicable under General Statute 143-
215.6A(a)(1).
In accordance with 15A NCAC 2L, a 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 remediation action on the part of the
permittee.
27. Lagoon Closure Procedures:
The following guidelines shall be met for closure of the two existing lagoons.
a. Sample the sludge in each lagoon in three locations (3 sludge samples per lagoon).
b. The following analytical procedures should be run on the sludge samples:
i Toxicity Characteristic Leaching Procedure (TCLP) SW-846 EPA Method 1331 for volatiles,
semi-volatiles and metals,
ii Ignitability SW-846 EPA Method 1010/1020,
iii Reactivity EPA OSW,
iv Corrosivity EPA Method 9045.
c. If the lagoon does not have a liner, then the underlying soil material should be sampled in three
locations and also analyzed for the TCLP procedures in (b.i). If the lagoon has a natural compacted
clay liner, then the clay liner should be sampled in three locations and analyzed for the TCLP
procedures in (b.i). If the lagoon has a synthetic liner, the soil material underneath the synthetic liner
should be sampled in three locations and analyzed for the TCLP procedures in (b.i). From a field
sampling point of view, the sludge and underlying clay or underlying soil material can be collected
using a core barrel sampler for the shallow soils, where the core barrel is driven into the
sludge./clay/soil matrix and later extracted.
d. If the sludge/clay/underlying soil material has TCLP concentrations that are above the TCLP
regulatory limits, the material is considered hazardous and the division of Waste
Management/Hazardous Waste Section should be contacted, and the material needs to be excavated.
e. If the sludge/clay/underlying soil material has TCLP concentrations that are below the TCLP
regulatory limits and below Groundwater 2L standards then the material may be left in place and the
lagoon closed without excavating the sludge.
f. If the sludge/clay/underlying soil material has TCLP concentrations that are below the TCLP
regulatory limits but are above the Groundwater 2L standards then there are two options as follows:
i. Excavate the material that is above Groundwater 2L standards, then proceed with lagoon closure.
ii Perform predictive calculations that demonstrate that the vertical leaching of the cortaminant in
question in the material will not cause an exceedance of Groundwater 2L standards in the
underlying surf cial groundwater saturated zone. This calculation would probably require the
need of site characterization of the subsurface hydrogeologic parameters of concern. The
predictive calculation would need to consider vertical leaching and subsequent mixing in the
groundwater saturated zone.

g. Once it is decided whether the sludge/underlying soil material can remain in place or needs to be
excavated, the following steps should be followed.
i. remove all water from the lagoons and dispose of properly,
ii remove all inflow piping, etc. to the lagoons,
iii if the liner (clay or synthetic) is being left in place it must be breached or ripped up to allow
water to infiltrate past the liner,
iv remove the earthen berms and grade the area to match the surrounding topography, in order to
prevent water from accumulating and ponding,
v add a vegetative cover to prevent soil erosion.
h. The final approval of the above procedure and analysis is granted by the Winston-Salem Regional
Groundwater Supervisor, Sherri Knight.
i. If any land disturbing activity associated with the above procedures will affect more than one acre of
land, an erosion and sedimentation control plan must be approved by the Land Quality Section of the
Division of Land Resources. The North Carolina general Statute 113A-57(4) requires that this plan
be submitted at least 30 days prior to beginning the land disturbing activity. Additional information
is available by contacting Mr. Matt Gant at [phone].

.0004 DEFiNITION,S
The lollowing definitions shall apply throughout this Subchapter.
(1) Activated Carbon Beds. A physlcaVchemical method for reducing soluble organic mwerlal from wastewater effluent; The column -type beds used in this
method will have a flow rate varying from two to eight gallons per minute per square foot and may be either upflow or downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant she;
(2) Aeralad Lagoons. A basin in which all solids are maintained In suspension and by which biological oxidation or organic matter is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of bringing about Intimate contact between air or high purity oxygen In a liquid by spraying, agitation or d€ffuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 16 hours.
(4) Ag6cuhurally managed sits. Any she on which a crop Is produced, managed, and harvested (Crop Includes grasses, grains, trees, etc.);
(5) Air Stripping. A process by which the ammonium ion is first convened to dissolved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benuehe, toluene, and xylene;
(6) Carbon Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volatilize and oxidize the
absorbed Impurities;
(7) Carbonaceous Stage. A swge of wastewater treatment designed to achieve 'secondary' effluent Ilmhs;
(a) Centrifuge. A mechanical device In wKch centrifugal force Is used to separate solids from liquids or to separate liquids of different densrlas;
(9) Chemical Addition Systems- The addition of chemical(s) to wastewater at an app%at€on point for purposes of improving solids removal, pH ad)uslmem,
alkalinity control, etc.; the capability to experiment with different chemicals and dllferard application points to achieve a specific result will be considered one
system; the capability to add chemicals) to dual units will be rated as one system; capability to add a chemical at a different application points for difierent
purposes will result In the systems being rated as separate systems;
(1o) Chemical Sludge Conditioning. The addition of a chemical compound such as lime, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to
its application to a dewatering device;
(11) Closed Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater containing Inorganic, non -toxic materials from sand, gravel,
crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of pumping Iaclthlas or any other appurlenances;
(12) Combined Removal or Carbonaceous DOD and Nitrogenous Removal by Nitrfflc ton- A single stage systems required to achieve permlt effluent Ilmhs on $OD
and ammonia nitrogen within the same biological reactor,
(13) Dechlodnatfon. The partlal or complete reducdion of residual chlorine In a liquid by any chemical ar physical process;
(14) Denhi-fi catlon Process. The conversion of nitrate -nitrogen to nitrooen oas'
