WQ0037287 issued January 23, 2020, and shall be subject to the following conditions and limitations:
I. SCHEDULES
1. In accordance with correspondence from the United States Environmental Protection Agency, any
unpermitted discharge to surface waters of effluent collected via the engineered material is a violation
of Section 301(a) of the Federal Clean Water Act. Accordingly, any unpermitted discharge of water
from the groundwater lowering system effluent storage pond shall be prohibited and shall require the
Permittee to report by telephone to the Wilmington Regional Office, telephone number [phone],
as soon as possible, but in no case more than 24 hours, or on the next working day following the
occurrence or first knowledge of the occurrence.
However, please note that per Session Law 2014-95, effluent collected via the engineered material and
its associated piping system shall be considered groundwater under this permit, as long as that water is
not discharged from the groundwater lowering system effluent storage pond. Accordingly, the
Permittee can utilize (e.g., irrigation) the water from the groundwater lowering system effluent storage
pond or discharge to the NPDES Permit No. NC0089524 to maintain the required 1-foot freeboard.
\[15A NCAC 02T .0108(b)(1)(A)\]
2.
accommodate the proposed flow increase if the Permittee applies for a permit modification to increase
the disposal capacity from the currently approved 250,000 GPD for each infiltration basin. The
Permittee can verify the storage capacity by providing freeboard records, flow records, and/or
utilization records. Also, the Permittee shall verify that the approved alternative design criteria
requirements pursuant to 15A NCAC 02T .0105(n) are still being met. \[15A NCAC 02T
.0108(b)(1)(A)\]
3. Upon completion of construction and prior to operation of the permitted modifications, the Permittee
shall submit an engineering certification from a North Carolina licensed Professional Engineer
certifying that the permitted facility has been constructed in accordance with G.S. 143-215.1,
Administrative Code Title 15A Subchapter 02T, this permit, and the Division-approved plans and
specifications. For phased and partially certified facilities, the Permittee shall retain the responsibility
to track further construction approved under this permit, and shall provide a final engineering
certification upon project completion. Mail the Engineering Certification to the Division of Water
Resources, Non-Discharge Branch, 1617 Mail Service Center, Raleigh, NC 27699-1617, or Non-
[e-mail]. \[15A NCAC 02T .0116(a)\]
4. The Permittee shall notify the Wilmington Regional Office, telephone number [phone], at least
two business days in advance of initial operation of the constructed facilities so that the Division can
conduct a startup inspection. \[15A NCAC 02T .0108(b)(1)(B)\]
WQ0037287 Version 2.1 Shell Version 200201 Page 2 of 11

5. Within 60 days of the effective date of this permit, monitoring well MW-1 shall be temporarily
abandoned by securing the wellhead to prevent access. Each monitoring well shall have a lockable cap,
and a compatible watertight cap or seal shall be placed onto each monitoring well riser pipe. \[15A
NCAC 02C .0108(c)(7), 02T .0108(b)(1)(B)\]
6. Prior to operation of the newly installed and modified facilities, a Final Operation and Maintenance
Plan shall be submitted for review. The plan shall be sent to the Division of Water Resources, Non-
Discharge Branch, 1617 Mail Service Center, Raleigh, NC 27699-1617 or Non-
[e-mail]. \[15A NCAC 02T .0108(b)(1)(B), 02T .0707(a)\]
7. The Permittee shall request renewal of this permit on Division-approved forms no later than August 4,
2025. \[15A NCAC 02T .0105(b), 02T .0109\]
II. PERFORMANCE STANDARDS
1. The Permittee shall maintain and operate the subject non-discharge facilities 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 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 disposal facilities. \[15A NCAC 02T
.0108(b)(1)(A)\]
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. \[15A NCAC 02T .0108(b)(1)(A)\]
3. Groundwater monitoring wells shall be constructed in accordance with 15A NCAC 02C .0108
(Standards of Construction for Wells Other than Water Supply), and any other jurisdictional laws and
regulations pertaining to well construction. \[15A NCAC 02C .0108\]
4. Effluent quality shall not exceed the limitations specified in Attachment A. \[15A NCAC 02T .0705(b)\]
5. Application rates, whether hydraulic, nutrient, or other pollutant, shall not exceed those specified in
Attachment B. \[15A NCAC 02T .0705(m)\]
6. High-rate infiltration sites permitted on or after December 30, 1983 have a compliance boundary that
is either 250 feet from the infiltration area, or 50 feet within the property boundary, whichever is closest
to the infiltration area. Any exceedance of groundwater standards at or beyond the compliance
boundary shall require corrective action. Division-approved relocation of the compliance boundary
shall be noted in Attachment B. Multiple contiguous properties under common ownership and
permitted for use as a disposal system shall be treated as a single property with regard to determination
of a compliance boundary. \[15A NCAC 02L .0106(d)(2), 02L .0107(b), 02T .0105(h), G.S. 143-
215.1(i), G.S. 143-215.1(k)\]
7. The review boundary is midway between the compliance boundary and the infiltration area. Any
exceedance of groundwater standards at or beyond the review boundary shall require preventative
action. \[15A NCAC 02L .0106(d)(1), 02L .0108\]
8. The Permittee shall apply for a permit modification to establish a new compliance boundary prior to
any sale or transfer of property affecting a compliance boundary (i.e., parcel subdivision). \[15A NCAC
02L .0107(c)\]
9. No wells, excluding Division-approved monitoring wells, shall be constructed within the compliance
boundary except as provided for in 15A NCAC 02L .0107(g). \[15A NCAC 02L .0107\]

b. Prohibits construction and operation of water supply wells within the compliance boundary; and
c. Reserves the right of the Permittee or the State to enter the property within the compliance boundary
for purposes related to the permit.
The Director may terminate the easement when its purpose has been fulfilled or is no longer needed.
