I. SCHEDULES
Within 90 days of permit issuance, the Permittee shall undertake and complete a groundwater study of
sufficient detail (e.g., define groundwater flow, effluent dispersion patterns, etc.) so as to ultimately
identify the source or sources of groundwater contamination (i.e. nitrate, ammonia, et al.) in several
monitoring wells for which NOVs were issued in 2015. Should the source of contamination be
identified as the Corolla Light W WTP #1, or other source owned by the Permittee, a detailed plan shall
subsequently be developed and implemented by the Permittee to alleviate the exceedances of the
groundwater standards. [15A NCAC 02T .0108(b)(2)]
2. 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 Iimitations 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 application.
[15A NCAC 02T .0105(d), 02T .0106, 02T .0109, 02T .0115(c)]
3. If the subject wastewater treatment or infiltration facilities are in noncompliance with the terms and
conditions of this permit, governing statutes or regulations, the subject facilities shall be connected to
an operational publicly owned wastewater collection system within 180 days of its availability. Prior
to the initiation of these connection activities, appropriate Division approval shall be received. [ I 5A
NCAC 02H .0404(e)]
II. PERFORMANCE STANDARDS
1. The subject non -discharge facilities shall be effectively maintained and operated at all times so there is
no discharge to surface waters, nor any contravention of groundwater or surface water standards. In
the event the facilities fail to perform satisfactorily, including the creation of nuisance conditions due
to improper operation and maintenance, or failure of the infiltration areas to adequately assimilate the
effluent, the Permittee shall take immediate corrective actions including Division required actions, such
as the construction of additional or replacement wastewater treatment or infiltration facilities. [G.S.
143-215.1, 143-213.3(a)]
2. This permit shall not relieve the Permittee of their responsibility for damages to groundwater or surface
water resulting from the operation of this facility. [ 15A NCAC 02B .0200, 02L .0100]
3. All wells constructed for purposes of groundwater monitoring shall be constructed in accordance with
15A NCAC 02C .0 10 8 (Standards of Construction for Wells Other than Water Supply), and any other

.0108(b)(1)]
5. Application rates, whether hydraulic, nutrient or other pollutant, shall not exceed those specified in
Attachment B. [ 15A NCAC 02T .0705(m)]
6. A usable green area shall be maintained for effluent disposal. The green area shall contain at least
1,000 square feet of open green area for each residential unit served, or 2,500 square feet per thousand
gallons per day of waste flow, whichever is less. A green area is defined as an area suitable for waste
disposal, either in its natural state or which has been modified by planting a vegetative cover of grasses
or low growing shrubbery. [15A NCAC 02H .0404(g)(7)]
WQ0006254 Version 4.0 Shell Version 151201 Page 2 of 8

This disposal system was individually permitted on or after December 30, 1983; therefore, the
compliance boundary is established at either 250 feet from the effluent disposal area, or 50 feet within
the property boundary, whichever is closest to the effluent disposal area. An exceedance of
groundwater standards at or beyond the compliance boundary is subject to remediation action according
to 15A NCAC 02L .0106(d)(2) as well as enforcement actions in accordance with North Carolina
General Statute 143-215.6A through 143-215.6C. [15A NCAC 02L .0106(d)(2), 02L .0107(b)]

review boundary shall require action in accordance with 15A NCAC 02L .0106. [15A NCAC 02L
.0106, 02L .0108]
9. The Permittee shall apply for a permit modification to establish a new compliance boundary prior to

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 621OD, 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
C. 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 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 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 Washington 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.
