Please note the following permit conditions have been removed since the last permit
issuance dated March 25, 2011:
➢ Old Condition 1.6. — This condition has been removed because the freeboard gauges have
been installed in the four high -rate infiltration basins.
➢ Old Condition 11.6. — This condition has been removed because the new Permittee is a
Privately -Owned Public Utility.
➢ Old Condition IV.13. — This condition has been removed because annual soil analysis testing
is not required for high -rate infiltration basins.
Please note the following permit conditions and attachments are new or have been modified
since the last permit issuance dated March 25, 2011:
➢ Condition LL — This condition was included in the previous permit issuances; however, the
requirements of this condition were never completed. Therefore, given that a follow-up
inspection has not occurred, and that the high -rate infiltration basins have been physically
modified several times since their original construction, the Permittee shall provide an
updated hydrogeologic investigation report.
➢ Condition It.10. — This condition requires any landowner who owns land within the
compliance boundary, but who is not the Permittee, to execute and file with the County
Register of Deeds an easement with the requirements listed in the said Condition. Please note
the previous permit was subject to this requirement under 15A NCAC 02L .0I07(f),
therefore, this condition is intended to voice this rule.
➢ Condition IV9. — This condition requires that the Permittec maintain a record of all residuals
removed from the facility.
➢ Attachment A — Old PPIs 001 and 002 have been combined into PPI 001, and the Phased
Flows are listed as footnotes. In addition, the effluent limits for Ammonia (00610) and
Nitrate (00620) have been removed since there is a Total Nitrogen (00600) limit of 4 mg/L.
Please also note that the monitoring frequency for the groundwater lowering system effluent
has been reduced to weekly, and that Fecal Coliform (31616) is now a requirement.
➢ Attachment C — This attachment has been modified to include the new monitoring wells
MW-1, MW-2 and MW-3, as well as their associated sampling requirements.
If any parts, requirements or limitations contained in this permit are unacceptable, the Permittee
has the right to request an adjudicatory hearing upon written request within 30 days following receipt of
this permit. This request shall be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings at 6714 Mail
Service Center, Raleigh, NC 27699-6714. Unless such demands are made, this permit shall be final and
binding.

1. 3 x Year monitoring shall be conducted in March, July & November; Annual monitoring shall be conducted every 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. The measurement
of pH shall be made after purging and prior to sampling for the remaining parameters.
3. 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. The measuring points (top
of casing) of all monitoring wells shall be surveyed relative to a common datum.
4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods:
a. Standard Method 6230D, PQL at 0.5 µg/L or less
b. Standard Method 62101), PQL at 0.5 pg/L or less
.c. EPA Method 8021, Low Concentration, PQL at 0.5 µglL or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 pg/L or less
e. Another method with prior approval by the Water Quality Permitting Section Chief
Any method used must meet the following qualifications:
a. A laboratory must be DWR certified to run any method used.
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 DWR. 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 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 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.
7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 1 and this attachment.
