Dear Mr. Venters:
John E. Skvarla, III
Secretary
Subject: Permit No. WQ0013348
Pamlico Regional Wastewater
Facilities (Bayboro, Oriental,
River Dunes, and Arapahoe)
Wastewater Irrigation System
Pamlico County
In accordance with your permit modification request received January 15, 2013 and additional
information received May 15, 2013, we are forwarding herewith Permit No. WQ0013348 dated July IS,
2013 to Bay River Metropolitan Sewer District for the operation of the subject wastewater treatment and
disposal facilities.
Modifications to this permit include permitting the operation of the Oriental Lagoon system as the
primary paeans of treatment for the Oriental WWTF instead of the previously permitted SBR WWTP
capable of producing reclaimed water. As such, permitted treatment capacity at the Oriental WWTF has
been reduced from 320,044 GPD to 200,000 GPD and effluent limits have been relaxed from reclaimed
water limits to the minimum degree of treatment for new facilities under 15A NCAC 02T .0505 (b)(3). It
should be noted that the compliance point for all effluent monitoring remains at the Oriental WWTF with
the exception of Fecal Coliform, which shall be monitored at the point of disinfection at the Bayboro
W WTF. %
This permit modification does not relieve BRMSD of its responsibility to resolve non-compliance
issues at either the Oriental WWTF or River Dunes Disposal Site. Accordingly, this permit includes
schedule conditions to properly abandon the inoperable Oriental SBR system, develop a closure or
maintenance plan for the failed infiltration basins at River Dunes, document or install proper flow
measuring devices at Oriental and automated irrigation shutoff equipment at Arapahoe, and permanently
disconnect the forcemain between Oriental and River Dunes. All disposal capacity has been removed
from River Dunes and further addition of effluent is prohibited.
Please note groundwater quality and freeboard monitoring is still required at the River Dunes
facility. Additionally, note that monitoring frequency for the Oriental and Bayboro WWTFs renxains
reduced at monthly versus the typical twice -per -month frequency typical of lagoon systems with total
flows > 0.5 MGD as per APS Domestic Wastewater Monitoring policies.

1. 3 X year monitoring shall be conducted in March, July & November for wells located at Arapahoe, Bayboro, and Oriental sites. Monthly monitoring shall be conducted for wells
located at the River Dunes site. Annual monitoring shall be conducted every November.
2. The measurement of water levels shall be made prior to purginethe 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 6210D, PQL at 0.5 gg/L or less
C. EPA Method 8021, Low Concentration, PQL at 0.5 gg/L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 gg/L or less
e. Another method with prior approval by the Aquifer Protection Section Chief
Any method used must meet the following qualifications:
a. A laboratory must be DWQ 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 gg/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 gg/L must be qualified (estimated) and reported.
If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Washington Regional Office Aquifer Protection Supervisor, telephone
number [phone], must be contacted immediately for further instructions regarding any additional follow-up analyses required.
WQ0013348 Version 2.8 Attachment C Page 1 of 2

6. If TOC concentrations greater than 10 mg11 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 sball be reported consistent with the nomenclature and location information provided in permit Figures, and this attachment,
