Dear Mr. Venters:
In accordance with your permit minor modification and renewal request received May 19, 2014,
and subsequent additional information received September 23, 2014 and January 7, 2015, we are
forwarding herewith Permit No. WQ0013348 dated January 21, 2015, to Bay River Metropolitan Sewer
District (BRMSD) for the continued operation of the subject wastewater treatment and irrigation facilities.
The modifications to the subject permit are as follows:
♦ Permit descriptions for Bayboro W WTF and Arapahoe Site are updated per your request
♦ Permit description for the non-functional S13R plant is removed.
♦ Infiltration basins I and 2 located at the River Dunes Site are removed from the permit.
Basin 3, which has received wastewater, shall be properly closed as stipulated under 15A
NCAC 02T,01050) before it may be removed from the permit. Condition 1.3 shall be met
in order to justify the closure for basin 3 and ensure public safety. We recommend that
immediate actions be taken to remove the existing synthetic liner and vegetation/trees
grown on basins that could pose safety risk to the public or install fence around the basin
perimeter.
♦ Groundwater monitoring requirements at the River Dunes Site are removed. All
monitoring wells located at this site shall be permanently abandoned in accordance with
Condition I.4.
♦ Please note that monitoring requirements for the effluent of Oriental lagoon system have
not been removed as requested. Monitoring of the Oriental treatment system is necessary
to assure that the treatment system is properly operated, functional, and capable of
producing effluent that meet the minimum criteria as stipulated in 15A NCAC 02T
.0108(c) and 02T .0505(b). However, only critical parameters are kept (i.e., four
parameters are removed including ammonia, nitrate, total nitrogen and chlorine residual,
and monitoring frequency for pH is reduced from 5xWeek to Weekly).
♦ Condition 11I.10 — Public access to the irrigation sites, wastewater treatment facilities,
and infiltration basin shall be prohibited pursuant to 15A NCAC 02T ,0505(q) and 02T
.0705(p).

I. 3 X year monitoring shall be conducted in March, July & November for wells located at Arapahoe, Bayboro, and Oriental sites. Annual monitoring shall be conducted every November.
2. The nicasuremcnt 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 62301), PQL at 0.5 µg/l. or less
b. Standard Method 62101). I'QI, at 0.5 pg/L or less
c. EPA Method 8021, Low Concentration. PQ1, at 0.5 µg/l. or less
d. FI'A Method 8260_ Loi Concentration_ PQL at 0.5 pg/I. 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 Vill of Standard Method 6230D.
C. The method used must provide a PQL o1'0.5 µg/L or less that must be supported by laboratory proficiency studies as required by DWR. Any constituents detected above the MDL but below
the PQI, 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 Washington Regional Office supervisor, telephone number [phone],
must be contacted immediately for further instructions regarding any additional follow-up analyses required.
WQ0013348 Version 3.0 Attachment C Page 1 of 2

6. if TOC concentrations greater than 10 mgiL are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identity the individual constituents
comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 rng/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 permit figures and this attachment.

Subject: Re-classification of Water Pollution Control Systern
Facility: Pamlico Regional Wastewater Facilities
Permit #: WQ0013348
Dear Mr. Venters:
In accordance with North Carolina General Statute 90A-37, the Water Pollution Control System
Operators Certification Commission is required to classify all water pollution control systems.
In accordance with 15A NCAC 8G .0202, classified facilities are required to designate one
Operator in Responsible Charge (CRC) and one or more back-up operators of the appropriate
type and grade.
The subject facility was originally classified as a Gracie 4 Biological Water Pollution Control
System and a Surface Ifni, tion System on April 9, 2007. Basted on a review of the draft permit
renewal for this facility, the Commission hereby removes the Grade 4 Biological Water
Pollution Control System classification effective today. The system remains classified as a
Surface Irrigation System.
As required by North Carolina Administrative Code 15A 8G .0201 and your permit, you must
designate and maintain one Operator in Responsible Charge (ORC) and at Ieast one Hack -up
ORC for this facility_ Your facility requires an ORC who holds an active Surface Irrigation
certification. In addition, your facility requires at least one Back-up ORC who holds an active
Surface Irrigation certification.

Mr. Chris Venters
January 15.2015
Page 2 of 2
Unless offierwise specified in the permit, the designated ORC is required to visit the system
weekly. The Back -lap ORC may act as surrogate for the ORC for a period:
(a) not to exceed 40 percent of the system visitations required pier calendar year; or
(h) not to exceed 120 consecutive calendar days when the ORC is absent due to the vacancy
of the ORC position or personal or familial illness.
To ensure our records are up to date, please complete and return the enclosed designation form
to this office. The form must be signed by the ORC, the Back-up ORC(s), and you or your
designee. All operators designated as ORC or Back-up ORC must be actively certified as
described above.
If you have questions concerning the facility classification or designation requirements, please
