existing permit).
This permit shall be effective from October 1, 2015 until September 30, 2020, shall void Permit
No. WQ0023896 issued April 12, 2013, and shall be subject to the conditions and limitations as specified
therein. Please pay particular attention to the monitoring requirements listed in Attachments A, B and C
for they may differ from the previous permit issuance. Failure to establish an adequate system for
collecting and maintaining the required operational information shall result in future compliance
problems.
For your convenience, customized electronic copies of your facility's NDMR and NDAR-1
reporting forms are available for download at: http://portal.nedenr.or web/wqlaps/lau/reporting.
Please note the following permit conditions have been removed since the last permit

➢ Old Condition I.5. -- This condition has been removed because monitoring well MW-2 has
been permanently abandoned.
➢ Old Condition I.6. -- This condition has been removed because the gauges in the wet weather
storage and secondary effluent storage basins have been installed.
➢ Old Condition IV.12. — This condition has been removed because the Well Construction
Record forms (GW-ls) for monitoring wells MW-3, MW-4, MW-5 and MW-6 have been
received.
Please note the following permit conditions and Attachments have been modified since the
last permit issuance dated April 12, 2013:
➢ Condition 1I.12.a. — The previous permit issuance included incorrect setback distances for
three parameters. Setback distances for spray irrigation were inadvertently used instead of
setback distances for drip irrigation. Accordingly, the setback distance from the wetted area
to: Any habitable residence or place of public assembly under separate ownership; Any
habitable residence or place of public assembly owned by the Permittee; and Any property
line have been changed to 100, 15 and 50 feet, respectively.
➢ Attachment A — Total Nitrogen (00600) has been added to the sampling regimen.
➢ Attachment B — Old wastewater irrigation site, Field A, has been removed from Attachment
B because this field has been decommissioned.
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

I. SCHEDULES
No later than six months prior to the expiration of this permit, the Permittee shall request renewal of
this permit on official Division forms. Upon receipt of the request, the Division will review the
adequacy of the facilities described therein, and if warranted, will renew the permit for such period of
time and under such conditions and limitations as it may deem appropriate. Please note Rule 15A
NCAC 02T .0105(d) requires an updated site map to be submitted with the permit renewal

1. 4 x Year monitoring shall be conducted in March, June, September & December; Annual monitoring shall be conducted every December_
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 December only, analyze by one of the following methods:
a_ Standard Method 6230D, PQL at 0.5 µg/L or less
b. Standard Method 6210D, PQL at 0.5 µg/L or less
c. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 µg/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 V111 of Standard Method 6230D.
c. The method used must provide a PQL of 0.5 µg/L or less that must be supported by laboratory proficiency studies as required by DWR Any constituents detected above the MIX but below
the PQL of 0.5 µg/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 Raleigh 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 I and this attachment.
