Dear Mr. Gallarda,
In response to your permit major modification request received on March 6, 2024, and subsequent
additional information received on June 6, 2024, we are forwarding herewith Permit No. WQ0037287 dated
August 14, 2024, to Pluris Hampstead, LLC for the construction and operation of the permitted
modifications and the continued operation of the existing wastewater treatment and high-rate infiltration
facilities.
Modifications to the subject permit are as follows:
➢ The Division has approved the 500,000 gallon per day (GPD) expansion wastewater treatment
plant (WWTP) and increased the permitted non-discharge disposal capacity accordingly to
1,000,000 GPD.
This permit is effective from the date of issuance through January 31, 2026, shall replace Permit
No. WQ0037287 issued on August 2, 2021, and is subject to the conditions and limitations therein. The
Permittee shall submit a renewal application no later than August 4, 2025.
Please pay 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 may result in future non-compliance.
The Division has removed the following permit conditions since the last permit issuance dated
August 2, 2021:
➢ Old Condition I.5 – The Division has removed this condition and replaced it with Condition
I.5.
➢ Old Condition II.3 – The Division has removed this condition because the Permittee has
constructed all proposed groundwater monitoring wells.

WQ0037287 Version 2.2 Shell Version 230725 Page 3 of 12
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 the Permittee shall
report 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 pursuant to Session Law 2014-95, effluent collected via the non-native
material (i.e., engineered) 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 (i.e., irrigation and amenity ponds) the water from the
groundwater lowering system effluent storage pond or discharge to the NPDES Permit No. NC0089524
to maintain the required one-foot freeboard. [15A NCAC 02T .0108(b)(1)(A)]
2. The Permittee shall address the groundwater lowering system effluent storage pond’s ability to
accommodate the proposed flow increase if the Permittee applies for a permit modification to increase
the disposal capacity from the currently approved 573,000 GPD (102.01 GPD/ft2) for Basin 1. 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
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 pursuant to 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. The Permittee shall submit the Engineering Certification via the Non-Discharge online
portal. [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 the initial operation of the constructed modifications so that the
Division can conduct a startup inspection. [15A NCAC 02T .0108(b)(1)(A)]
5. Within 60 days of this permit’s effective date, the Permittee shall permanently abandon monitoring
well MW-1. The Permittee shall permanently abandon each monitoring pursuant to the requirements
in 15A NCAC 02C .0113(d). Within 30 days of abandonment, the Permittee shall submit a Well
Abandonment Record (Form GW-30) for each permanently abandoned monitoring well. The Permittee
shall submit the Well Abandonment Records via the Non-Discharge online portal. [15A NCAC 02C
.0113(d), 02C .0309, 02T .0108(b)(1)(B)]
6. Prior to the operation of the modified facilities, the Permittee shall submit an amended Operation and
Maintenance Plan. The Permittee shall submit the amended Operation and Maintenance Plan via the
Non-Discharge online portal. [15A NCAC 02T .0108(b)(1)(B), 02T .0707(a)]
7. If the permitted facilities change ownership or the Permittee changes its name, the Permittee shall
submit a permit modification request on Division-approved forms within 90 days of the change of
ownership. The Permittee shall comply with all terms and conditions of this permit until the Division
transfers the permit to the successor-owner. [G.S. 143-215.1(d3)]
8. 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]

WQ0037287 Version 2.2 Shell Version 230725 Page 4 of 12
II. PERFORMANCE STANDARDS
1. The Permittee shall operate and maintain the subject wastewater treatment and high-rate infiltration
facilities so there is no discharge to surface waters, nor any contravention of groundwater or surface
water standards. In the event the facilities do not perform as designed, 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 its responsibility for contravention of groundwater or
surface water standards resulting from the operation of this facility. [15A NCAC 02T .0108(b)(1)(A)]
3. Effluent quality shall not exceed the limitations specified in Attachment A. [15A NCAC 02T .0705(b)]
4. The Permittee shall not infiltrate effluent in exceedance of the hydraulic rates specified in Attachment
B. [15A NCAC 02T .0705(m)]
5. For high-rate infiltration sites originally permitted on or after December 30, 1983, the Division has
established the compliance boundary 250 feet from the infiltration area boundary or 50 feet within the
property boundary, whichever is closest to the infiltration area boundary. Any exceedance of
groundwater standards at or beyond the compliance boundary shall require the Permittee to take
corrective action. 15A NCAC 02T .0705(y) prohibits subsurface groundwater lowering drainage
systems within the compliance boundary. The Division shall note any Division-approved relocation
of the compliance boundary in Attachment B. The Division shall consider multiple contiguous
properties under common ownership and permitted for use as a disposal system as a single property
regarding the determination of a compliance boundary. [15A NCAC 02L .0106(e), 02L .0107(b), 02L
.0107(c), 02L .0107(f), 02T .0105(h)]
6. The Division has established the review boundary midway between the compliance boundary and the
infiltration area boundary. Any exceedance of groundwater standards at or beyond the review boundary
shall require the Permittee to take preventative action. [15A NCAC 02L .0106(d), 02L .0108]
7. The Permittee shall notify the Division of any sale or transfer of property affecting a compliance
boundary (i.e., parcel subdivision). [15A NCAC 02L .0107(l)]
8. The Permittee or any landowner who owns land within the compliance boundary shall not construct
any water supply wells within the compliance boundary. [15A NCAC 02L .0107(i)]
