Wastewater Collection System Extension Permit
Union County
In accordance with your application received December 22, 2017, we are forwarding herewith Permit No.
WQ0039558 dated January 9, 2018 to the Union County Public Works (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effective from the date of issuance until rescinded and shall be subject to the conditions and limitations as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.
Please pay particular attention to the following conditions contained within this permit:
Condition 11.1: This permit shall not be automatically transferable; a request must be made and approved.
Condition 1.1.4: Requires that the wastewater collection facilities be properly operated and maintained in
accordance with 15.A NCAC 2T .0403 or any individual system -wide collection system
permit issued to the Permittee.
It shall be the responsibility of the Perrnittee to ensure that the as -constructed project meets the appropriate
design criteria and rules. Failure to comply may result in penalties in accordance with North Carolina
General Statute §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.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within 30 days following receipt of this permit. This
request must be in the form of a written petition, conforming to Chapter 15013 of North Carolina General

Persons reporting any of the above occurrences shall file a spill report by completing and submitting
Part I of Form CS-SSO (or the most current Division approved form) within five days following first
knowledge of the occurrence. This report must outline the actions taken or proposed to be taken to
ensure that the problem does not recur. Part II of Form CS-SSO (or the most current Division
approved form) can also be completed to show that the SSO was beyond control. [G.S.
215.1C(a1)]
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)]
7. 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
Minim -um 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
Page 6 of 8

discouraged by the Division and may not be approved, thus requiring replacement or repair prior to
certification & activation. [15A NCAC 02T .0116]
8. 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. [ I5A 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. [15A
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)]

PLANNING ASSESSMENT ADDENDUM (PAA)
Pump Station (Name or Number):
Given that:
a. The proportion and amount of Obligated, Not Yet Tributary Daily Flow (C) accounts for
% and MGD of the Available Capacity (E) in Pump Station
; and that
b. The rate of activation of this obligated, not yet tributary capacity is currently approximately
MGD per year; and that
c. A funded Capital Project that will provide the required planned capacity, namely
is in design or under construction with
planned completion in ; and/or
d. The following applies:
Therefore:
Given reasonably expected conditions and planning information, there is sufficient justification to
allow this flow to be permitted, without a significant likelihood of over -allocating capacity in the
system infrastructure.
I understand that this does not relieve the collection system owner from complying with G.S. 143-
215.67(a) which prohibits the introduction of any waste in excess of the capacity of the waste
disposal system.

a. WWTP Facility Name: Enter the name of the WWTP that will receive the wastewater flow.
b. WWTP Facility Permit #: Enter the NPDES or Non -Discharge number for the WWTP receiving the
wastewater flow.
c. WWTP facility's permitted flow, MGD: From WWTP owner's NPDES or Non -Discharge permit.
d. Estimated obligated flow not yet tributary to the WWTP, MGD: This includes flows allocated to other
construction projects not yet contributing flow to the collection system. Flows allocated through
interlocal agreements or other contracts not yet contributing flow to the collection system are also
included. For POTWs that implement a pretreatment program, include flows allocated to industrial
users who may not be using all of their flow allocation. Please contact your Pretreatment Coordinator
for information on industrial flow tributary to your WWTP.
As ofJanuary 15, 2008 the POTW should have reviewed flow allocations made over the last two years
and reconciled their flow records, to the best of their ability, so it is known how much flow has been
obligated and is not yet been made tributary to the WWTP, in accordance with local policies and
procedures employed by the reporting entity.
e. WWTP facility's actual avg. flow, MGD: Previous 12 month average.
f. Total flow for this specific request, MGD: Enter the requested flow volume.
g. Total actual and obligated flows to the facility, MGD Equals [d + e + f1
h. Percent of permitted flow used: Equals [(g / c}* 100]
For example:
On January 15 a POTW with a permitted flow of 6.0 MGD, reported to the Regional Office that there
is 0.5 MGD of flow that is obligated but not yet tributary. The annual average flow for 2007 is 2.7
MGD. There is a proposed flow expansion of 0.015 MGD.
The first Form FTSE submitted after January 15, 2008 may have numbers like this:
c. = 6.0 MGD
d. = 0.5 MGD
e. = 2.7 MGD
f. = 0.015 MGD
g. = 3.215 MGD
h. = 53.6 %
The next Form FTSE may be updated like this with a proposed flow expansion of 0.102 MGD:
c. = 6.0 MGD
d. = 0.515 MGD
e. = 2.73 MGD
f. = 0.102 MGD
g. = 3.349 MGD
h. = 55.8 %
Each subsequent FTSE form will be updated in the same manner.

Section II
List the pump station name or number and approximate pump station firm capacity, approximate design
average daily flow (A) approximate current average daily flow (B), and the obligated, not yet tributary flow
through the pump station (C) for each pump station that will be impacted by the proposed sewer extension
project. Calculate the total current flow plus obligated flow (D=B+C) and the available capacity (E=A-D).
Include the proposed flow for this project with other obligated flows that have been approved for the pump
station but are not yet tributary (C).
Firm capacity is the maximum pumped flow that can be achieved with the largest pump out of service as
per the Minimum Design Criteria.
Design Average Daily Flow is the firm capacity of the pump station divided by a peaking factor (pf) of not
less than 2.5.
If the available capacity (E) for any pump station is < 0, then prepare a planning assessment for that pump

Planning Assessment Addendum Instructions
Submit a planning assessment addendum for each pump station listed in Section II where available capacity
is <0.
A planning assessment for Kaw Creek PS (see example data above) may be performed to evaluate whether
there is significant likelihood that needed improvements or reductions in obligated flows will be in place
prior to activating the flows from the proposed sewer extension project.
If the system decides to accept the flow based on a planning assessment addendum, it is responsible to
manage the flow without capacity related sanitary overflows and must take all steps necessary to complete
the project or control the rate of flow to prevent sanitary sewer overflows.
The planning assessment may identify a funded project currently in design or construction, or a planned
project in the future not yet funded but in a formal plan adopted by the system. The system should carefully
weigh the certainty of successful timely project completion for any expansion, flow management diversion
or infiltration and inflow elimination projects that are the foundation of a planned solution to capacity
tracking and acceptance compliance.
For example:
Given that:
a. The proportion and amount of obligated, not yet tributary flow accounts for 24 % and 0.080
MGD of the committed flow in Pump Station Kaw Creek; and that
b. The rate of activation of this obligated, not yet tributary capacity is currently approximately 0.01
MGD per year; and that
c. A funded capital project that will provide the required planned capacity, namely
is in design or under construction with
planned completion in ; and/or
d. The following applies:
The master plan and ten year capital plan contain recommended scope and funding for a capital project
entitled Kaw Creek Pump Station upgrade with funding planned in July 2014. This project is planned to
add 0.100 MGD to the firm capacity of the pump station by October 2015. Inclusion of this proposed
capital project as a condition of this FIow Tracking/Acceptance for Sewer Extension Permit Application
elevates this project's priority for funding and construction to be implemented ahead of the activation of
obligated., not yet tributary flows in amounts that exceed the firm pump station capacities identified in
Section II above.
Therefore:
Given reasonably expected conditions and planning information, there is sufficient justification to allow
this flow to be permitted, without a significant likelihood of over -allocating capacity in the system
infrastructure.

BONTERRA VILLAGE - PHASE 4B
Project Narrative
The proposed project is a single family home subdivision with associated, utilities, stormwater
management facilities and landscaping. Phase 4B of the project consists of 100 single family
lots. The proposed sanitary sewer extension is designed to convey 100% domestic sanitary
sewer from proposed development to 8"' sanitary sewer mains from phase 1 and phase 4A of
the development and ultimately to an existing Union County Public Works 15" sanitary sewer
main running parallel to an unnamed tributary to North Fork. Crooked Creek.
Flow is calculated as follows:
100 - Single Family Homes
100 x 285 gpd= 28,500
Total Proposed Flow (PHASE 4B) = 28,500 GPD
