Please note the following permit conditions are new or modified since the last permit
issuance dated May 2, 2011:
➢ Condition II.8. — This condition requires the Permittee to modify their permit prior to the sale
of any land that may affect the existing compliance boundary.
➢ Condition II. I La. — This condition has been expanded to include a footnote explaining why
the setbacks to surface waters, groundwater lowering ditches and subsurface groundwater
lowering drainage systems have been reduced to 100 feet from 200 feet.
➢ Condition IL I Lb. — Since the Juniper Swamp irrigation fields were permitted after September
1, 2006, these fields are subject to the 15A NCAC 02T .0506(a) setbacks. These setbacks
were mistakenly omitted from the previous permit issuance.
➢ Condition III.10. — This condition requires that the residuals generated from the wastewater
treatment facilities shall be disposed or utilized in accordance with 15A NCAC 02T .1100.
➢ Attachment A — Please note that the Points Prior to Irrigation (PPI) in Attachment A have
been heavily reorganized and condensed for clarity. Changes to each PPI are listed as
follows:
o PPI 001 — The Units of Measure (UOM) for Fecal Coliform (31616) and Plant Available
Nitrogen (WQ09C) have been changed to #/100 mL and mg/L, respectively.
o PPI 002 — This PPI is for WWTF Effluent once the Juniper Swamp irrigation fields are in
operation, but prior to operation of the Juniper Swamp high -rate infiltration basin. This
PPI includes a new effluent flow limit that was previously listed as PPI 003 in the permit
dated May 2, 2011. In addition, since the Juniper Swamp irrigation fields were permitted
after September 1, 2006, these fields are subject to the effluent limits in 15A NCAC 02T
.0505(b)(1). These effluent limits were mistakenly omitted from the previous permit
issuance. Also, please note that the UOM for Fecal Coliform (31616) has been changed
to 9/100 mL.
o PPI 003 — This PPI is for WWTF Effluent once the Juniper Swamp high -rate infiltration
basin has been constructed. This PPI includes two new effluent flow limits that were
previously listed under PPIs 002 and 004 in the permit dated May 2, 2011. In addition,
the UOM for Fecal Coliform (31616) has been changed to #/100 mL. Please note that
once the Juniper Swamp high -rate infiltration become operational, PPI 003 shall be the
active PPI and PPIs 001 and 002 shall be suspended, regardless of whether or not the
Juniper Swamp irrigation fields are operational.
o PPI 004 — This PPI is for the groundwater lowering system effluent, and shall only be
reported upon operation of the Juniper Swamp high -rate infiltration system. Please note
that the UOM for Fecal Coliform (31616) has been changed to #/100 mL, and the PCS
code for Total Dissolved Solids has been changed from 70295 to 70300.

b. The method used must, at a minimum, include all the constituents listed in Table VIII of Standard Method 6230D.
c. The method used must provide a PQL of 0.5 pg/L or less that 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 of 0.5 pg/L must be qualified (estimated) and reported.
5. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Wilmington Regional Office Aquifer Protection Supervisor, telephone
number [phone], must be contacted immediately for further instructions regarding any additional follow-up analyses required.
6. 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 mg1L, 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.
Monitoring wells shall be reported consistent with the nomenclature and location information provided in the attached figures and this attachment.

1. 3 x Year monitoring shall be conducted in March, July & November.
2. The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top of the casing.
3. The measuring points (top of well casing) of all piezometer wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top
of casing) of all monitoring wells shall be surveyed relative to a common datum.
