Dear Mr. Lucas:
In accordance with your application received April 27, 2020, we are forwarding herewith Permit No.
WQ0040089 MODIFICATION dated May 7, 2020 to Stanly County (Permittee) for the construction and
operation upon certification of the subject wastewater collection system extension. This permit shall be
effective from the date of issuance until rescinded and shall be subject to the conditions and limitations as
specified therein. This cover letter shall be considered a part of this permit and is therefore incorporated
therein by reference.
Permit WQ0040089 was originally issued on June 28, 2018 for the construction and operation of
approximately 1,372 linear feet of 8-inch public gravity sewer; 120 gallons per minute pump station with
duplex pumps, onsite audible and visual high water alarms, telemetry and a permanent generator with automatic
transfer switch; as well as 2,845 linear feet of 4-inch force main to serve the Riverstone Business Park - Phase
I, and the discharge of 21,000 gallons per day of collected wastewater into the West Stanly WWTP existing
sewerage system. This permit modification will reduce the permitted discharge from 21,000 GPD to 15,750
GPD, and no change in the permitted sewer line or pump station.
Please pay particular attention to the following conditions contained within this permit:
Condition II.1: This permit shall not be automatically transferable; a request must be made and approved.

actions taken or proposed to be taken to ensure that the problem does not recur. Part 11 of Form CS-SSO (or the
Page 6 of 10
most current Division approved form) can also be completed to show that the SSO was beyond control. [G.S. 143-
215.1C(al)]
6. Construction of the gravity sewers, pump stations, and force mains shall be scheduled so as not to interrupt service
by the existing utilities nor result in an overflow or bypass discharge of wastewater to the surface waters of the State.
[ 15A NCAC 02T.0108(b)]
Upon completion of construction and prior to operation of these permitted facilities, the completed Engineering
Certification form attached to this permit shall be submitted with the required supporting documents to the address
provided on the form. A complete certification is one where the form is fully executed and the supporting documents
are provided as applicable. Any wastewater flow made tributary to the wastewater collection system extension prior
to completion of this Engineer's Certification shall be considered a violation of the permit and shall subject the
Permittee to appropriate enforcement actions.
If the permit is issued to a private entity with an Operational Agreement, then a copy of the Articles of
Incorporation, Declarations/Covenants/Restrictions, and Bylaws that have been appropriately filed with the
applicable County's Register of Deeds office shall be submitted with the certification.
A complete certification is one where the form is fully executed and the supporting documents are provided as
applicable. Supporting documentation shall include the following:
a. One copy of the project construction record drawings (plan & profile views of sewer lines & force mains) of the
wastewater collection system extension. Final record drawings should be clear on the plans or on digital media
(CD or DVD disk) and are defined as the design drawings that are marked up or annotated with after construction
information and show required buffers, separation distances, material changes, etc.
b. One copy of the supporting applicable design calculations including pipe and pump sizing, velocity, pump cycle
times, and level control settings, pump station buoyancy, wet well storage, surge protection, detention time in
the wet well, and force main, ability to flush low points in force mains with a pump cycle, and downstream sewer
capacity analysis. If a portable power source or pump is dedicated to multiple stations, an evaluation of all the
pump stations' storage capacities and the rotation schedule of the portable power source or pump, include travel
timeframes, shall be provided.
c. Changes to the project that do not result in non-compliance with this permit, regulations, or the Minimum Design
Criteria should be clearly identified on the record drawings, on the certification in the space provided, or in
written summary form.
Prior to Certification (Final or Partial): Permit modifications are required for any changes resulting in non-
compliance with this permit (including pipe length increases of 10% or greater, increased flow, pump station design
capacity design increases of 5% or greater, and increases in the number/type of connections), regulations, or the
Minimum Design Criteria. Requested modifications or variances to the Minimum Design Criteria will be reviewed
on a case -by -case basis and each on its own merit. Please note that variances to the Minimum Design Criteria should
be requested and approved during the permitting process prior to construction. After -construction requests are
discouraged by the Division and may not be approved, thus requiring replacement or repair prior to certification &
activation. [ 15A NCAC 02T .0116]
Gravity sewers installed greater than ten percent below the minimum required slope per the Division's Gravity Sewer
Minimum Design Criteria shall not be acceptable and shall not be certified until corrected. If there is an unforeseen
obstacle in the field where all viable solutions have been examined, a slope variance can be requested from the
Division with firm supporting documentation. This shall be done through a permit modification with fee. Such
variance requests will be evaluated on a case -by -case basis. Resolution of such request shall be evident prior to
completing and submitting the construction certification. [ 15A NCAC 02T.0105(n)]

9. A copy of the construction record drawings shall be maintained on file by the Permittee for the life of the wastewater
collection facilities. [ 15A NCAC 02T .0116]
10. Failure to abide by the conditions and limitations contained in this permit; 15A NCAC 2T; the Division's Gravity
Sewer Design Criteria adopted February 12, 1996, as applicable; the Division's Minimum Design Criteria for the
Fast -Track Permitting of Pump Station and Force Mains adopted June 1, 2000, as applicable; and other supporting
materials may subject the Permittee to an enforcement action by the Division, in accordance with North Carolina
General Statutes § 143-215.6A through § 143-215.6C, construction of additional or replacement wastewater collection
facilities, and/or referral of the North Carolina -licensed Professional Engineer to the licensing board. [I 5A NCAC
02T .0104; 15A NCAC 02T .0108(b-c)]
11. In the event that the wastewater collection facilities fail to perform satisfactorily, including the creation of nuisance
conditions, the Permittee shall take immediate corrective action, including those as may be required by this Division,
such as the construction of additional or replacement facilities. [ 15A NCAC 02T .0110; 15A NCAC 02T .0108(b)]
12. The issuance of this permit shall not exempt the Permittee from complying with any and all statutes, rules,
regulations, or ordinances that may be imposed by the Division any other Federal, State, or Local government
agencies which have jurisdiction or obtaining other permits which maybe required by the Division or any other
Federal, State, of Local government agencies. [G.S. 143-215.1(b)]
