SUBJECT: WATER AND SEWER FLOW ACCEPTANCE
HERITAGE AT MARVIN SUBDIVISION
NEW TOWN ROAD, MARVIN, NC. 28173
CLTWATER TRACKING# 20245991
After analysis of the sanitary sewer associated with the proposed design of project, 20245991,
HERITAGE AT MARVIN SUBDIVISION, it was determined that there is sufficient capacity to
accommodate the proposed sewer flow of 15,960 gallons per day(84 lots x 190 gpd/lot) at the
connection point(s) indicated on the submitted utility plan for transmission to the McAlpine Creek
Wastewater Treatment Plant; NPDES permit number NC0024970, for treatment. This acceptance of
flow is based upon the existing capacity of the designated publicly owned treatments works.
Charlotte Water(CLTWater) agrees to furnish water to the subject project. The water quality to the
subject project is regulated by the State Drinking Water Act Amendments of 1986 and The Water
Supply Management Plan, PWS ID # 0160010 on file with the Public Water Supply Section of
NCDEQ. However, CLTWater cannot guarantee a constant pressure or quality of flow.
The applicant should understand that due to the involvement of other agencies and continuing
growth of the water and sewer system, the ability to provide service for future projects cannot be
guaranteed nor reserved. Connection to the CLTWater and sewer system is accepted on a first
come, first served basis.

Instructions for Flow Tracking form (FTSE)and Planning Assessment Addendum(PAA)
Section I
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'spermitted flow, MGD: From WWTP owner's NPDES or Non-Discharge permit.
d. Estimated obligated flow not vet 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 to
for information on industrial flow tributary
to your WWTP.
As of January 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+fJ
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 station
if the system has future specific plans related to capacity that should be considered in the permitting process.

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 t 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 Flow 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.

Revised Residential Flow Reduction Approval
Union County
Dear Ms. Panico:
On March 29, 2019,the Division of Water Resources (Division) received a revision request for the
previously approved adjusted daily sewage flow rate (flow reduction)that would apply to all permitted
but not yet tributary residential connections and all future residential connections within the Twelve
Mile WWTP and Crooked Creek WWTP service areas.
In accordance with 15A NCAC 02T.0114(f)(2), the Division has evaluated the revision request as well as
additional information received on June 19, 2019, and based on the data submitted and the Division of
Water and Infrastructure (DWI) guidance,the Division hereby approves for use by Union County Public
Works a revised adjusted daily sewage design flow rate with the following conditions:
• The flow reduction is applicable to residential single family dwellings only.
• The minimum flow for 1 and 2 bedroom dwellings shall be 140 gallons per day.
• Each additional bedroom above two bedrooms shall increase the volume by 70 gallons per day
per bedroom.
• This flow reduction shall not apply to sewer extension applications and/or permits for any other
public or private organizations whose wastewater flows are or might become tributary to the
Union County collection system (WQCS00054).
• For permitting purposes,allocations may be permitted utilizing a flow of 280 gallons per day
per lot based on a service-area average of 4 bedrooms per lot. If a residential development is
anticipated to have a limited number of bedrooms OR is anticipated to exceed an average of
4-bedrooms per lot, permitted flows shall be calculated based on the per-bedroom reduction.
o Union County shall evaluate the average number of bedrooms per lot on an annual basis
and shall submit this information to the PERCS Unit by June 30"annually. Should the
average number of bedrooms constructed during the preceding calendar year exceed
the average of 4 bedrooms per lot,this approval must be reevaluated by the State prior
to continuing to use the approved permitting allocation of 280 gallons per lot.

Future sewer extension applications should be made using the flow reduction amount stated above. All
other aspects of the permitting process remain unchanged, and all applications must be in compliance
with the statues, rules, regulations and minimum design criteria as certified by the owner and engineer.
Regardless of the adjusted design daily wastewater flow rate at no time shall the wastewater flows
exceed the effluent limits defined in the NPDES Permit for the treatment facility or exceed the capacity
of the sewers downstream of any new sewer extension or service connections)
The granting of this flow reduction does not prohibit the Division from reopening, revoking, reissuing
and/or modifying the flow reduction as allowed by the laws, rules, and regulations contained in 15A
NCAC 02T, NCGS 143-215.1, or as needed to address changes in State and/or Federal regulations with
respect to wastewater collection systems, protection of surface waters and/or wastewater treatment.
