(Pressure & Vacuum sewer systems are not to be included as part of this application package)
INSTRUCTIONS: Indicate that you have included/addressed the following list of required application package items by
checking the space provided next to each applicable item. Failure to submit all required items will lead to your application
being returned as incomplete. Forms are available from the web site or by calling the Regional Office serving your county:
http://h2o. enr state. nc. us/peres/Collection%20Systems/CollectionSystemApplications. html
A. Application Form - Submit one original and one copy of the completed and appropriately executed application
form. The application should include a project narrative describing the final build -out design (i.e. system and/or
pump station to ultimately serve 500 homes, but flow for only 100 homes being requested now). For modifications,
clearly explain the reason for the modification (i.e. adding another phase, changing line size/length, etc.). Only
include the modified information in this permit application - do not duplicate project information that has already
been included in the original permit.
Any changes to this form will result in the application being returned. The Division of Water Quality (Division) will
only accept application packages that have been fully completed with all applicable items addressed. You do not
need to submit detailed plans and specifications unless you respond NO to Item B(13)
Separate applications should be made for non-contiguous sewer systems
JK B. Application Fee - Submit a check in the amount of $480 made payable to: North Carolina Department of
Environment and Natural Resources (NCDENR). Checks shall be dated within 90 days of application submittal.
❑ C. Certificates of Public Convenience and Necessity — If the application is being submitted in the name of a
privately -owned public utility, submit two copies of the Certificate of Public Convenience and Necessity (CPCN)
which demonstrates that the public utility is authorized to hold the utility franchise for the area to be served by the
sewer extension. If a CPCN has not been issued, provide two copies of a letter from the North Carolina Utilities
Commission's Public Staff that states that an application for a franchise has been received, that the service area
is contiguous to an existing franchised area, and/or that franchise approval is expected. The project name in the
CPCN or letter must match that provided in Item A(2)a of this application.
❑ D. Operational Agreements — Submit one original and two copies of a properly executed operational agreement, as
per 15A NCAC 02T .0115, if the application is submitted by a private applicant and will be serving residential or
commercial lots (e.g., houses, condominiums, townhomes, outparcels, etc.) that will be sold to another entity. If
the applicant is a home or property owner's association, use Form HOA 02/03. If the applicant is a developer,
use Form DEV 02/03. EVEN IF THE PROJECT MAY BE TURNED OVER TO A MUNICIPALITY UPON
COMPLETION, FORM DEV 02/03 IS REQUIRED.
E. Downstream Sewer, WWTF Capacity and Flow Tracking/Acceptance — FORM FTSE 10/07 (Flow
Tracking/Acceptance for Sewer Extension Permit Applications) is required with every application. The applicant
(and owners of downstream sewers, pump stations and/or treatment facilities submitting FORM FTSE-10/07)
certifies that the addition of the volume of wastewater to be permitted in this project has been evaluated along the
route to the receiving treatment plant, and that the flow from this project will not cause capacity related sanitary
sewer overflows or overburden any downstream pump station en route to the receiving wastewater treatment
plant. Where the applicant is not the owner of the downstream sewer, submit two copies of FORM FTSE 10/07
from the owner of the downstream sewer and owner of the WWTF, if different. The flow acceptance indicated in
FORM FTSE-10/07 must not expire prior to permit issuance and must be dated less than one year prior to the
application date. Submittal of this application and FORM FTSE-10/07 indicates that owner has adequate
capacity and will not violate G.S. 143-215.67(a). Intergovernmental agreements or other contracts will not be
accepted in lieu of project -specific FTSE 10/07.
F Map — Submit an 8.5-inch by 11-inch COLOR copy of a USGS Topographic Map of sufficient scale to identify the
entire project area and the closest surface waters. Each map or maps must show the location of the sewer line
and pump stations and be of reproducible quality. Include a street level map showing the downstream connection
point, and the permit number for the downstream sewer, if known.
FTA 12/07

❑ G. Stream Classifications — Watershed Classification Attachment (Form WSCAS-12/07) If any portion of the
sewer system project is within 100 feet of any surface water or wetlands, the Watershed Classification Attachment
may. need to be completed. A variance must be requested for encroachment within required setbacks or buffers
pursuant to 2T .0305 (f) and be indicated in Item B-13 with supporting documentation/justification provided.
❑ H Environmental Assessments — If this project is subject to an Environmental Assessment (EA) [15A NCAC
01C], this application cannot be used. Send the project application on the most current version of Form
PSFMGSA to the Design Management Unit, 1633 Mail Service Center, Raleigh, NC 27699-1633. Applications
cannot be accepted until a Finding of No Significant Impact (FONSI) or Environmental Impact Statement (EIS)
has been issued. A copy is to be submitted with that permit application.
❑ I. Flow Direction — Many wastewater treatment systems are entering into agreements for regionalization efforts
and emergency treatment capacity. Parts of the system are installed so that the wastewater flow can be directed
to more than one treatment facility. If this is the case with this project, please indicate in 13(12) and give the permit
number of the second treatment facility.
'Pl J. Certifications — Section C
The application must be certified by both the applicant and the design engineer who is a North Carolina
Registered Professional Engineer (PE). The applicant signature must match the signing official listed in Item
A(lb). The PE should NOT certify the application if he/she is unfamiliar with 15A NCAC Chapter 2T, the Gravity
Sewer Minimum Design Criteria (most recent version) and the Minimum Design Criteria for the Fast -Track
Permitting of Pump Stations and Force Mains (most recent version), as applicable to the project.

SEWAGE PUMP STATION AND FORCE MAIN EXTENSION
DESIGN NARRATIVE
1. GENERAL
The project area is located in eastern Moore County in the town of Cameron. The
purpose of the project is to enable the Cameron Elementary School (CES) to convey
their wastewater discharge to Moore County Public Works and eliminate the current
practice of wastewater disposal via septic tanks and leach fields. Currently CES has
three (3) septic tanks, one (1) grease trap and two (2) leach fields to dispose of their
wastewater generated on site. The off site disposal of the wastewater will permit the
land to be used for other purposes.
A lift station will be constructed on the south-eastern side of the school property
and the force main will be installed inside the North Carolina Department of
Transportation's (NCDOT) right-of-way from the elementary school and discharge into
a manhole in the Town of Vass.
2. EXISTING SITE AND CONDITIONS
The land gently rolls with grades generally ranging from 0% to 8% with loamy
sands overlaying thick layers of sandy clay loam. The soils mainly consist of Fuquay
loamy sand with other Dothan and Ailey loamy sands. These soils are well drained with
low runoff potential. Wastewater from the school drains with the lay of the land and
flows north to septic tanks and ultimately leach fields which have a very mild slope 0%
to 2%.
The septic tanks and leach fields date back to the 1940's when the school was
built and have been maintained but the septic tank accesses are slabs of concrete which
require heavy equipment to facilitate operations and maintenance. Concrete that has
not been lined with any corrosion inhibitors will typically reach its useful design life in
fifty (50) years or less depending on the compounds formed in the waste. The school
board has realized that Cameron Elementary School's septic tanks have reached their
useful design life and has approved an off -site wastewater conveyance system.

3. WASTEWATER CONVEYANCE SYSTEM
A. Sewage Pump Station Site
The location of the sewage pump station at the Cameron Elementary School site
was selected based on a meeting with Moore County Public School System staff and
McGill Associates on January 6, 2011 using the following criteria:
1. The availability of three (3) phase power. Three (3) phase power enters the
school site at the south-east corner.
2. Access for maintenance vehicles. The service entrance to the school cafeteria,
heating oil tank and teacher parking is adjacent to the proposed site.
3. The ability to gravity feed the wastewater generated on -site to the pump
station. A proposed gravity collection system from the north end of campus
to the south-east will serve the existing buildings on campus and open up
other areas for future building.
B. Force Main Route
Two (2) force main routes were reviewed and the selected route is described
below. A 4-inch force main provides the optimum hydraulics for both routes with
respect to power demands and pumping capacity. The selected route runs east on the
south side of Hwy 24-27 then runs on the west side of US-1 Business south to the
discharge manhole in the Town of Vass, see map G-001.
The force main utilizes existing road right-of-ways to minimize the need for
easement acquisition and to provide better access for maintenance in the event of a line
break. The route will have two (2) creek bores under blue line streams and cross over
NCDOT culverts that show up as blue line streams on the United States Geological
Survey (USGS) quad sheet. The proposed force main will be installed deeper than the
minimum cover due to parallel installations of potable water lines. US-1 Business has a
16-inch ductile iron potable water line running in the west shoulder and a 6-inch water
line in the east shoulder; therefore it will be necessary to install the force main 18-inches
deeper than the bottom of the water line to meet North Carolina Department of
Environment and Natural Resources (NCDENR) separation requirements. Two (2)

creek crossings will be bored to minimize impacts to the streams and eliminate the need
to obtain environmental permits from the US Army Corps of Engineers (USACOE) and
the North Carolina Division of Water Quality (NCDWQ).
4. RECOMMENDATIONS
McGill Associates, P.A. recommends Alternative #1 for ease of construction and
the most economical solution for wastewater conveyance. Wastewater will have a six
(6) day residence time in the force main and will produce corrosive hydrogen sulfide
compounds; therefore it is recommended that the pump station have a chemical feed
system that directly injects into the force main to reduce the production of these
compounds. The receiving manhole and adjacent pump station will be lined with a
corrosion inhibiting compound to protect the structural integrity of the manhole and
wetwell. The force main will be equipped with an emergency by-pass connection,
which, in the event the pump station has a catastrophic failure, a portable pump must
be utilized to discharge directly into the force main. The force main will have multiple
emergency by-pass connections to be used for cleaning and flushing the force main.
The force main route has large sags and low flows which will cause solids to accumulate
in the low points in the line. Flushing the line as part of a maintenance program will
clear the force main of solids and provide many years of reliable service. It is
recommended that the force main be flushed at a velocity of 3.5 feet per second or 310
gallons per minute (gpm). A temporary flow meter will provide the maintenance staff
useful information with respect to flow rates during flushing activities.
Recommendations Summary:
• Alternate Route #1 — 24,600-feet of 4-inch PVC force main along US-1
Business.
• Line receiving manhole and adjacent wetwell with corrosion resistant coating.
• Inject Chemical feed at the pump station to reduce formation of corrosive
compounds.
• Flush line — as part of a maintenance operation at 310 gpm.
• Install a by-pass pump connection station at pump station and several points
along force main to facilitate cleaning the force main.

Dear Ms. Henson:
Please find enclosed for your review and approval the following items related to the
above referenced project:
• One (1) original and one (1) copy of the Fast Track Application for Gravity
Sewers, Pump Stations and Force Mains (FTA 12/07)
• One (1) original and one (1) copy of the Flow Tracking Form (FTSE 10/07)
• Two (2) copies of a project narrative with a location map and design
calculations for the pump station and force main
• A check in the amount of $480 to cover the application fee
The proposed project includes the installation of a new lift station and approximately
24,600 linear feet of 4-inch diameter force main and related appurtenances to convey
wastewater from the Cameron Elementary School to the existing wastewater collection
system serving the Town of Vass.
The force main crosses under two (2) blue line streams via directional drill and at
all other stream crossings the force main crosses over a NCDOT culvert. Therefore, this
project will have no impact to the waters of the State and does not require an
Environmental Assessment.
