PLANNING ASSESSMENT ADDENDUM (PAA)
Submit a planning assessment addendum for each pump station listed in Section II where Available Capacity is<
0.
Pump Station(Name or Number):
Given that:
a. The proportion and amount of Obligated,Not Yet Tributary Daily Flow(C)accounts for
0 %and 0 MGD of the Available Capacity(E) in Pump Station
Mellott PS ; 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:
The full buildout design flow for this station is 306 gpm(0.4406 MGD) or 122 gpm(0.1757
MGD ADF). This represents a peak flow from planned residential development within the
service basin. No additional flow above the 306 gpm(0.4406 MGD) or 122 gpm(0.1757
MGD ADF) is anticipated. Should additional flow be planned, a separate application for the
upgrade of this facility will be submitted.
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.

Dear Mr. Smith:
On November 6, 2022, the Division of Water Resources (Division) received a request for an
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 Chatham Park
Associated Areas (Oldham Tract, Mellott Tract, Grantham Tract, Womble Tract, CPI Parcel 1,
CPI Parcel 2, Clark Tract, CPI Parcel 3, CPT Parcel 4, CPT Parcel 5, CPI Parcel 6, Townsend
Tract) service area.
In accordance with 15A NCAC 02T .01 14(f)(2), the Division has evaluated the request, and
based on the data submitted, the Division hereby approves for use by Chatham Park Investors,
LLC an 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 I- and 2- bedroom dwellings shall be 120 gallons per day.
• Each additional bedroom above two bedrooms shall increase the volume by 60 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 City of Sanford collection system (WQCS00047) or the Chatham Park
Water Recovery Center(NC0020354).
Future sewer extension applications should be made using the now reduction amount stated
above. All other aspects of the permitting process remain unchanged, and all applications must

be in compliance with the statutes, 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 permit for the treatment facility or exceed the
capacity capaci!y of the sewers downstream of any new sewer extension or service connections .
In accordance with 15A NCAC 02T .0114(f), the Division periodically requires reassessment of
wastewater flow data associated with the collection system or the receiving wastewater treatment
plant as applicable to confirm the suitability of the approved flow reduction value. Chatham Park
Investors, LLC shall submit documented, representative data in accordance with 15A NCAC 02T
.01 14(f)(1)(A-H)prior to November 30, 2032. Failure to submit the required data by this date
will result in this flow reduction approval letter becoming null and void. Upon review of the
data, the Division shall either reapprove, modify or not grant reapproval for the previously
approved flow reduction value.
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.

project installs approximately 3,800 linear feet of 6-inch PVC sanitary sewer
force main; approximately 200 linear feet of 6-inch DIP sanitary sewer force
main; approximately 3,500 linear feet of 8-inch PVC gravity sanitary sewer;
approximately 200 linear feet of 8-inch DIP gravity sanitary sewer; and
approximately 30 linear feet of 12-inch DIP gravity sanitary sewer. The project
also includes construction of a duplex sanitary sewer pump station.
The project is approved for the following permits: Town of Pittsboro Riparian
Venture IV atltldl,tg Buffer Authorization, Town of Pittsboro Construction Drawing Approval, and
Chatham County Soil Erosion and Sedimentation Control. The proposed

REVISED DESIGN NARRATIVE
1.0 PROJECT DESCRIPTION
The Mellott Pump Station and Utilities project installs approximately 3,800 linear feet of 6-inch
PVC sanitary sewer force main; approximately 200 linear feet of 6-inch DIP sanitary sewer force
main; approximately 3,500 linear feet of 8-inch PVC gravity sanitary sewer; approximately 200
linear feet of 8-inch DIP gravity sanitary sewer; and approximately 30 linear feet of 12-inch DIP
gravity sanitary sewer. The proposed sanitary sewer force main begins at the proposed pump
station and extends to an existing 12-inch PVC force main along Suttle Road (SR 1809). The
proposed gravity sanitary sewer is a new gravity outfall installed for future development and
extends from a proposed manhole near Suttles Rd (SR 1809) and extends to the proposed pump
station, paralleling the proposed force main. The project also includes construction of a duplex
sanitary sewer pump station and water service line. The total project has approximately 2.72
acres of disturbed area.
The parcel on which the construction is proposed is owned by 15-501 East LLC. However, the
applicant is Chatham Park Investors LLC, an affiliate of 15-501 East LLC, as this business will be
funding the installation of the infrastructure. Additionally, the flow reduction for this parcel
(attached to this submittal) has been issued to Chatham Park Investors, LLC. The previous
permit WQ0043971 was issued to 15-501 East, LLC. This modification changes the applicant to
Chatham Park Investors, LLC.
2.0 EXISTING SYSTEM
The proposed gravity sanitary sewer will tie-in to the proposed wet well at Mellott Pump
Station. The proposed sanitary sewer force main will tie-in to an existing force main along
Suttles Road (SR 1809), owned by the Town of Pittsboro. The existing force main along Suttles
Road, permitted under WQ0010602, discharges to the Section 5.2 Interceptor, which is permitted
under WQ0040741. The flow will ultimately be discharged to the Chatham Park Water Recovery
Center (CPWRC), which is permitted under NC0020354.
3.0 PROPOSED ADDITIONS
The proposed construction will add approximately 3,800 linear feet of 6-inch PVC sanitary
sewer force main; approximately 200 linear feet of 6-inch DIP sanitary sewer force main;
approximately 3,500 linear feet of 8-inch PVC gravity sanitary sewer; approximately 200 linear
feet of 8-inch DIP gravity sanitary sewer; and approximately 30 linear feet of 12-inch DIP
gravity sanitary sewer. The proposed sanitary sewer force main begins at the proposed pump

station and extends to an existing 12-inch PVC force main along Suttle Road (SR 1809). The
proposed gravity sanitary sewer is a new gravity outfall installed for future development and
extends from a proposed manhole near Suttles Rd (SR 1809) and extends to the proposed pump
station, paralleling the proposed force main. The project does not include the permitting of new
sanitary sewer flows. Other consultants will provide permits for the new flows in future projects
for the development. Anticipated flow to this pump station will consist of single family and
multi-family residential flows.
The proposed sanitary sewer pump station, identified as Mellott Pump Station, is designed for a
firm capacity of 0.44 MGD. The pump station construction will consist of one 10' by 11.5' wet
well with two submersible pumps, one meter vault with bypass piping, odor control with bulk
chemical storage, electrical and control panel rack, and a generator. Permit WQ0043971 was
approved with an operating point of 165 GPM which represents a temporary interim operating
point. A modification to this existing permit includes changing the flow to a 306 GPM operating
point to represent the buildout conditions of the pump station. The pump station is designed for
permanent onsite backup generator; therefore, a power reliability plan has not been included
with this submittal. The construction will also include a water service line with yard hydrant.
An access drive is proposed by others, as shown on the plans.

MEMORANDUM
To: Chatham Park Investors, LLC
CC: Wesley Hutchinson - McKim &Creed; Robbie Oldham - WithersRavenel
From: Rick Trone
Date: 4/4/2023
Project: Mellott Pump Station and Utilities(WR#02150098.60)
Subject: 404/401/Riparian Buffer Permitting - Non-Notifying Authorization
This memorandum is in reference the USACE 404 and NCDWR 401/Riparian Buffer permitting
requirements for this installation of a sewer line.
The proposed alignment will result in a perpendicular crossing of two streams: Stream 1
(intermittent)and Stream 3 (intermittent)utilizing traditional open-cut methods of installation.WR
delineated the area on 1/25/2018 and the USACE field reviewed the site on 8/02/2018.
USACE 404 Approval
The proposed sewer line extension is eligible for 404 authorization under the USACE Nationwide
Permit 58 (NWP 58) for Utility Line Activities (see attached). Per the conditions requiring
notification under NWP 58, submittal of a pre-construction notification (PCN)to the USACE prior
to commencing the activity is required if:
1) A section 10 permit is required - Not applicable. There are no Section 10 waters within the
review area.
2) The discharge will result in the loss of greater than 1/10-acre of waters of the United States -
The proposed installation of the sewer line will be conducted via open-cut to cross Stream
1 and Stream 3. All proposed stream impacts for installation of the sewer line will result in
temporary impacts which are not considered a loss of waters of the US. Upon construction,
no riprap or hard structures will remain. There are no proposed permanent impacts.
Therefore, the proposed project will not result in a "loss" of waters of the US.
The proposed sewer line construction does not meet the NWP 58 conditions requiring submittal
of a PCN. The proposed project qualifies for a non-notifying NWP 58 and submittal of a PCN to,
or receipt of written authorization from the USACE is not required.
NCDWR 401 Approval
The proposed sewer line construction is eligible for 401 authorization under NCDWR Water
Quality General Certification No. 4276 (WQC 4276) for Utility Lines. Per general conditions of
WQC 4276, written authorization from NCDWR is required if the activity meets any one of the
following thresholds or circumstances:
a) if any of the conditions of this General Certification cannot be met;
Project meets all of the conditions of General Certification No. 4276.

b) Total temporary impacts to streams greater than 500 feet within the entire utility project
Total temporary impacts to streams greater than 500 feet within the entire utility project.
The proposed project will result in temporary stream impacts of 56 linear feet.
c) Anypermanent impacts to streams - All proposed stream impacts are temporary. There are
no proposed permanent stream impacts.
d) Total permanent impacts to wetlands or open waters equal to or greater than one-tenth(1/10)
acre within the entire utility project - Not applicable. There are no proposed permanent
impacts to wetlands or streams.
e) Anystream restoration orstream relocation - Not applicable
f) Any high-density project,as defined in 15A NCAC 02H.1003(3)and by the density thresholds
specified in 15A NCAC 02H .1017, (which meets sub-conditions i, ii, iii, iv)- Not applicable.
The proposed project is not a high-density project.
g) Any permanent impacts to waters, or wetlands adjacent to water, designated as: ORW
(including SA1),HQW(including PNA),SA, WS-1, WS-11 or North Carolina or National Wild and
Scenic River - Not Applicable. Onsite waters drain to Haven Creek and the Haw River,
which has a water quality classification of WS-IV;NSW.
h) Any permanent impacts to coastal wetlands or Unique Wetlands(UWL) - Not Applicable.
j) Any impacts to subject water bodies and/or state regulated riparian buffers along subject
water bodies in the Jordan Lake basin unless:
i. The activities are listed as "Exempt" or "Deemed Allowable" from these rules - The
proposed crossings are classified as "Allowable" in the Jordan Lake Buffer Rules.
ii. A Buffer Authorization Certificate is issued by the NC Division of Coastal Management -
Not Applicable
iii. A Buffer Authorization Certificate is issued by a delegated or designated local government
implementing a state riparian buffer program pursuant to 143-215.23 - The proposed
project is located within the jurisdiction of the Town of Pittsboro which is a delegated
municipality and implements the Jordan Lake Riparian Buffer Rules through their
riparian buffer ordinance (Section 4.2 of the LIDO). Impacts to riparian buffers for
construction of the proposed sewer crossings will be reviewed by the Town of
Pittsboro and issued a Buffer Authorization Certificate. Therefore, condition iii is met
and therefore does not require notification to NCDWR. The proposed sewer line
construction does not meet any conditions requiring written authorization from
NCDWR, and therefore does not require submittal of a PCN to, nor receipt of written
authorization from NCDWR.
Based on the information provided above, the proposed temporary stream impacts do not require
written authorization from the USACE nor NCDWR. Therefore, construction may begin at any
time and coordination with the USACE nor NCDWR is not required prior to construction.

USACE NWP 58
EXCERPT

Nationwide Permit 58
Utility Line Activities for Water and Other Substances
Effective Date: March 15, 2021 / Expiration Date: March 14, 2026
Authorities: Sections 10 and 404
Activities required forthe construction, maintenance, repair, and removal of utility lines
for water and other substances, excluding oil, natural gas, products derived from oil or
natural gas, and electricity. Oil or natural gas pipeline activities or electric utility line and
telecommunications activities may be authorized by NWPs 12 or 57, respectively. This
NWP also authorizes associated utility line facilities in waters of the United States,
provided the activity does not result in the loss of greater than 1/2-acre of waters of the
United States for each single and complete project.
Utility lines: This NWP authorizes discharges of dredged or fill material into waters of
the United States and structures or work in navigable waters for crossings of those
waters associated with the construction, maintenance, or repair of utility lines for water
and other substances, including outfall and intake structures. There must be no change
in pre-construction contours of waters of the United States. A "utility line" is defined as
any pipe or pipeline for the transportation of any gaseous, liquid, liquescent, or slurry
substance, for any purpose that is not oil, natural gas, or petrochemicals. Examples of
activities authorized by this NWP include utility lines that convey water, sewage,
stormwater, wastewater, brine, irrigation water, and industrial products that are not
petrochemicals. The term "utility line" does not include activities that drain a water of the
United States, such as drainage tile or french drains, but it does apply to pipes
conveying drainage from another area.
Material resulting from trench excavation may be temporarily sidecast into waters of the
United States for no more than three months, provided the material is not placed in such
a manner that it is dispersed by currents or other forces. The district engineer may
extend the period of temporary side casting for no more than a total of 180 days, where
appropriate. In wetlands, the top 6 to 12 inches of the trench should normally be
backfilled with topsoil from the trench. The trench cannot be constructed or backfilled in
such a manner as to drain waters of the United States (e.g., backfilling with extensive
gravel layers, creating a french drain effect).Any exposed slopes and stream banks
must be stabilized immediately upon completion of the utility line crossing of each
waterbody.
Utility line substations: This NWP authorizes the construction, maintenance, or
expansion of substation facilities associated with a utility line in non-tidal waters of the
United States, provided the activity, in combination with all other activities included in
one single and complete project, does not result in the loss of greater than 1/2-acre of
waters of the United States. This NWP does not authorize discharges of dredged or fill
material into non-tidal wetlands adjacent to tidal waters of the United States to
construct, maintain, or expand substation facilities.
i

Foundations for above-ground utility lines: This NWP authorizes the construction or
maintenance of foundations for above-ground utility lines in all waters of the United
States, provided the foundations are the minimum size necessary.
Access roads: This NWP authorizes the construction of access roads for the
construction and maintenance of utility lines, including utility line substations, in non-
tidal waters of the United States, provided the activity, in combination with all other
activities included in one single and complete project, does not cause the loss of greater
than 1/2-acre of non-tidal waters of the United States. This NWP does not authorize
discharges of dredged or fill material into non-tidal wetlands adjacent to tidal waters for
access roads. Access roads must be the minimum width necessary (see Note 2, below).
Access roads must be constructed so that the length of the road minimizes any adverse
effects on waters of the United States and must be as near as possible to pre-
construction contours and elevations (e.g., at grade corduroy roads or geotextile/gravel
roads). Access roads constructed above pre-construction contours and elevations in
waters of the United States must be properly bridged or culverted to maintain surface
flows.
This NWP may authorize utility lines in or affecting navigable waters of the United
States even if there is no associated discharge of dredged or fill material (see 33 CFR
part 322). Overhead utility lines constructed over section 10 waters and utility lines that
are routed in or under section 10 waters without a discharge of dredged or fill material
require a section 10 permit.
This NWP authorizes, to the extent that Department of the Army authorization is
required, temporary structures, fills, and work necessary for the remediation of
inadvertent returns of drilling fluids to waters of the United States through sub-soil
fissures or fractures that might occur during horizontal directional drilling activities
conducted for the purpose of installing or replacing utility lines. These remediation
activities must be done as soon as practicable, to restore the affected waterbody.
District engineers may add special conditions to this NWP to require a remediation plan
for addressing inadvertent returns of drilling fluids to waters of the United States during
horizontal directional drilling activities conducted for the purpose of installing or
replacing utility lines.
This NWP also authorizes temporary structures, fills, and work, including the use of
temporary mats, necessary to conduct the utility line activity. Appropriate measures
must be taken to maintain normal downstream flows and minimize flooding to the
maximum extent practicable, when temporary structures, work, and discharges of
dredged or fill material, including cofferdams, are necessary for construction activities,
access fills, or dewatering of construction sites. Temporary fills must consist of
materials, and be placed in a manner, that will not be eroded by expected high flows.
After construction, temporary fills must be removed in their entirety and the affected
areas returned to pre-construction elevations. The areas affected by temporary fills
must be revegetated, as appropriate.

Notification: The permittee must submit a pre-construction notification to the district
engineer prior to commencing the activity if: (1) a section 10 permit is required; or (2)
the discharge will result in the loss of greater than 1/10-acre of waters of the United
States. (See general condition 32.) (Authorities: Sections 10 and 404)
Note 1: Where the utility line is constructed, installed, or maintained in navigable waters
of the United States (i.e., section 10 waters) within the coastal United States, the Great
Lakes, and United States territories, a copy of the NWP verification will be sent by the
Corps to the National Oceanic and Atmospheric Administration (NOAA), National Ocean
Service (NOS), for charting the utility line to protect navigation.
Note 2: For utility line activities crossing a single waterbody more than one time at
separate and distant locations, or multiple waterbodies at separate and distant
locations, each crossing is considered a single and complete project for purposes of
NWP authorization. Utility line activities must comply with 33 CFR 330.6(d).
Note 3: Access roads used for both construction and maintenance may be authorized,
provided they meet the terms and conditions of this NWP. Access roads used solely for
construction of the utility line must be removed upon completion of the work, in
accordance with the requirements for temporary fills.
Note 4: Pipes or pipelines used to transport gaseous, liquid, liquescent, or slurry
substances over navigable waters of the United States are considered to be bridges,
not utility lines, and may require a permit from the U.S. Coast Guard pursuant to the
General Bridge Act of 1946. However, any discharges of dredged or fill material into
waters of the United States associated with such pipelines will require a section 404
permit (see NWP 15).
Note 5: This NWP authorizes utility line maintenance and repair activities that do not
qualify forthe Clean Water Act section 404(f) exemption for maintenance of currently
serviceable fills or fill structures.
Note 6: For activities that require pre-construction notification, the PCN must include
any other NWP(s), regional general permit(s), or individual permit(s) used or intended to
be used to authorize any part of the proposed project or any related activity, including
other separate and distant crossings that require Department of the Army authorization
but do not require pre-construction notification (see paragraph (b)(4) of general
condition 32). The district engineer will evaluate the PCN in accordance with Section D,
"District Engineer's Decision." The district engineer may require mitigation to ensure that
the authorized activity results in no more than minimal individual and cumulative
adverse environmental effects (see general condition 23).
GENERAL CONDITIONS
Note: To qualify for NWP authorization, the prospective permittee must comply with the
following general conditions, as applicable, in addition to any regional or case-specific

Resubmittal for the Fast Track Sewer System Expansion Application
Mellott Pump Station and Utilities
Chatham, NC
Submittal Review Comments and Responses
The following comments pertain to the initial review comments received for the Riparian
Buffer Authorization for the subject project (WQ0043971, Mellott Pump Station and
Utilities). Comments issued via email from Elaine Wild,received on August 14t",2023,are
incorporated below into the final comments.
1. Please provide clarification on whether,upon completion of the project, the permit will
be transferred from Chatham Park Investors,LLC to the Town of Pittsboro.
The permit for the pump station and utilities will be transferred from Chatham Park
Investors LLC to the Town of Pittsboro upon completion of construction. A separate
submittal will be submitted to the State at that time to update the permit owner.
2. Please clarify the wastewater treatment facility(WWTF) and receiving downstream
sewer information.
The proposed pump station will convey flow to the Chatham Park Water Recovery
Center(NC0020354)upon completion. As indicated in the application,this station is
being permitted at zero flow. Subsequent permit applications will be submitted to
allocate flow against the pump station by the respective design engineer as
appropriate. An FTSE from inclusive of current actual plus obligated flow has been
included in this resubmittal.
3. Although there is currently zero flow, a Flow Tracking for Sewer Extensions (FTSE)
Form is required. The WWTF specified in Section IV of the application needs to verify
that it has adequate capacity to accept the wastewater when the project is complete and
in operation and will not violate G.S. 143-215.67(a). Please refer to Section E of the
Application Instructions for further information.
a. Please make sure to clearly explain the wastewater flow in the Planning
Assessment Addendum.
Please find a completed FTSE attached to the submittal. The proposed flow to this
lift station will consist of residential flow only. The design of the station has
included proposed buildout flows for the development area and is sized
appropriately to accommodate anticipated peak flow at 306 gpm. A planning
assessment addendum has been included with this resubmittal.
4. Please provide the Buffer Authorization Certificate from the Town of Pittsboro,if
available.
Please find the Riparian Buffer Authorization from the Town of Pittsboro attached to
this submittal.
