Due to the elevation of the existing tie in outfall Salisbury -Rowan Utilities would like to request a variance to allow matching of inverts in to allow the proposed pipe to have
adequate cover between the top of pipe and the existing creek bed. The current design is to have the proposed 10" s.s. matching the existing 18"s.s. invert in into the manhole. The
invert out is a tenth lower the then invert in elevation, allowing for fall across the manhole. The sanitary sewer line is designed to meet other Minimum Design Criteria, and will not
be adding any additional sewer flow to the existing outfall. It will just be tying into the existing outfall at a more efficient location and angle.

Subject: Sewer Variance Request for the City of Salisbury Martin Luther King Ball Field Sewer
Salisbury -Rowan Utilities (SRU) is preparing plans for the realignment of an existing sewer main. The purpose of this
sewer realignment is to eliminate a problem with surcharging in the current alignment. The existing sewer line is
outdated, and under the City of Salisbury's municipal Ball field on South Martin Luther King Avenue. Due to the age, and
location of the existing sewer, SRU is proposing to realign the sewer line to a larger sewer outfall across Town Creek
(class C Stream). The proposed sewer line will consist of 5 new manholes, approximately 609 Lf of 10" ductile iron pipe,
and a creek crossing. Due to the elevation of the existing tie in outfall Salisbury -Rowan Utilities would like to request a
variance to allow matching of inverts in to allow the proposed pipe to have adequate cover between the top of pipe and
the existing creek bed. The current design is to have the proposed 10" s.s. matching the existing 18"s.s. invert in into the
manhole. The invert out is a tenth lower the then invert in elevation, allowing for fall across the manhole. The sanitary
sewer line is designed to meet other Minimum Design Criteria, and will not be adding any additional sewer flow to the
existing outfall. It will just be tying into the existing outfall at a more efficient location and angle.
Attached is a drawing of the proposal, C2.01. Please review this sheet and If you should require any addition information
from me for this variance request please let me know.

Chris,
I have read your email and taken a look at the attached drawing. The type of alternative design that you are requesting
is typically able to be approved by our office and your proposal appears to be a reasonable solution to dealing with
existing site conditions. However we are unable to grant any approval of alternative design until a permit application is
submitted to the Division. After you have submitted your permit application along with hardcopies of supporting
information to the Regional Office, we can then officially review and potentially approve your submittal. Until that time
we can only accept what you have submitted as preliminary information. If you have any questions please call me at
[phone].
Thanks,
Seth

Subject: Sewer Variance Request for the City of Salisbury Martin Luther King Ball Field Sewer
Salisbury -Rowan Utilities (SRU) is preparing plans for the realignment of an existing sewer main. The purpose of this
sewer realignment is to eliminate a problem with surcharging in the current alignment. The existing sewer line is
outdated, and under the City of Salisbury's municipal Ball field on South Martin Luther King Avenue. Due to the age, and
location of the existing sewer, SRU is proposing to realign the sewer line to a larger sewer outfall across Town Creek
(class C Stream). The proposed sewer line will consist of 5 new manholes, approximately 609 Lf of 10" ductile iron pipe,
and a creek crossing. Due to the elevation of the existing tie in outfall Salisbury -Rowan Utilities would like to request a
variance to allow matching of inverts in to allow the proposed pipe to have adequate cover between the top of pipe and
the existing creek bed. The current design is to have the proposed 10" s.s. matching the existing 18"s.s. invert in into the
manhole. The invert out is a tenth lower the then invert in elevation, allowing for fall across the manhole. The sanitary
sewer line is designed to meet other Minimum Design Criteria, and will not be adding any additional sewer flow to the
existing outfall. It will just be tying into the existing outfall at a more efficient location and angle.

from me for this variance request please let me know.

MARTIN LIJTHER KING BALL FIELD SEWER
P N ATTACHMENT
The Salisbury Rowan Utilities department (SRU) is proposing to realign an
existing sewer to eliminate problems with surcharging. Roots and debris
within a portion of the system, coupled
with awkward alignments and gradual
slopes under the Martin Luther King (MLK)
Ball Field have created a 'bottleneck' and
resulted in numerous overflows.. These
overflows are intercepted by an existing
drainage ditch that parallels an existing rail
road, and discharges into Town Creek.
Photo 1 was taken on 06 July 2010. Evidence of recent overflows (debris)
is visible for several hundred feet down the adjacent drainage ditch.
Approximately 750 feet downstream of
the ditch's confluence with Town Creek,
algal growth is excessive (Photo 2) and
indicates a water quality concern that
these periodic overflows may be
exacerbating.
complaints tor area
In addition to unsightly debris and water
quality concerns near the municipal ball
field, odors have become the source of
esidents and users of the facility.
To remedy these problems SRU is proposing to realign a portion of this
sewer. A ten inch sewerline comes into the park from the west via the
manhole shown above. It serves a 95-acre area on the west side of the
rail road tracks (Figure 4). From here the existing sewer continues 490 feet
under the ball field, where it picks up additional sewer lines from the north
and flows east to the Salisbury WWTP.
SRU is proposing to retire the 490 foot connection under the ball field, and
redirect flows to an existing newer sewerline on the south side of Town
Creek. The new line will be ductile iron, the same diameter (1 0-inches) as
that being replaced, and 609 feet long. Five new manholes will be
needed. No new capacity or service area is being added as part of this
project.

The new alignment will follow the edge of the
existing ball field fences, as illustrated in Photo 3.
The red line illustrates the new alignment.
Temporary impacts to exercise equipment and
a paved walking trail will be minimal and limited
to construction. After the project is complete,
these facilities will be reinstalled and no
permanent impacts to the facility are
expected.
To reduce impacts to Town Creek and its
riparian areas, SRU is proposing to utilize an
existing cleared corridor through the trees.

Photo 4 illustrates the new line's location
as it approaches Town Creek. Clearing
will be minimized, and contractors will be
instructed to perform all work from the
existing cleared areas to the extent
practicable. An existing overhead
power line right-of-way will be crossed
perpendicularly as required by its owner.
The sewer will cross perpendicular to
Town Creek, and conned with an existing sewerline on the south side of
Town Creek (Photo 5). This line also
transfers wastewater to the Salisbury
WWTP. RJG&A Biologist Chris Hopper
visited the project area on 06 July 2010
to conduct stream and wetland
delineations and search for cultural,
historic, and rare species concerns along
project alignments.

Two wetlands were identified in the project
area, and one stream crossing (Figure 2).
The first wetland (photo 6), a wetland ditch
that parallels the existing railroad corridor is a
manmade feature that is dominated by
rushes (Juncos), and Cattails (Typho). It is 2-3

feet wide, and runs perpendicular across the construction corridor. After
construction is complete this feature will
revert to its pre-existing condition and
no loss of jurisdictional waters will result.
The second wetland (photo 7) occurs
inside the tree line on the south side of
the ball fields and north of Town Creek.
This feature was not delineated in its
entirety, as it extends well beyond the
project area. The width shown in Figure
2 remains constant, but it extends
southwest to Town Creek and will not be impacted. This wetland is a
linear depression that begins immediately west of the construction
corridor. SRU staff are aware of this feature, and have agreed to install silt
fencing around it prior to allowing any ground disturbing activities.
One stream crossing will be required to build the project as proposed;
Town Creek (photo 8). The stream is a
perennial Class 'C' tributary of High Rock
Lake, and is 25 to 30 feet wide at the
proposed crossing. Because of the
elevation of the stream bed and tie-in
sewerline, directional drilling is not possible.
The crossing will be open cut, and after
completion the banks and bed will be
returned to pre -construction contours and
stabilized with rip -rap. The project will utilize
an existing thirty-foot wide clearing to approach the crossing to minimize
disturbance of riparian vegetation. Flows will be diverted via pump -
around during construction. Design engineers plan to construct the
crossing during the winter dry -season.

a. Pipelines within the road right-of-way, existing or proposed roads: Test density
every 12-inches (2 lifts) of placed backfill at intervals of 200 feet, minimum one
per day.
b. Pipeline under lawns or cross-country: Test density every 12-inches (2 lifts) of
placed backfill at intervals of 500 feet, minimum one per day.
B. Flushing
1. At completion of work, lines shall be thoroughly cleaned by flushing with water to
remove all dirt and debris.
2. Pipeline shall be flushed at a rate of at least 2.5 feet per second for a duration suitable to
the Engineer/Owner.
3. City water may be used (when available and a bulk water permit is purchased) to flush
sewer lines or an approved source of non -potable water (must be free of any chemicals,
silt, or debris) may be used to flush sewer lines.
4. All flush water must be collected in a plugged manhole and pumped out. Sewer flush
water shall not be allowed to enter the City's sewer system.
C. Obstructions/Visual Inspection
I. The pipe shall be visually inspected from manhole to manhole using lights, mirrors, or
other devices (CCTV) for visual inspection. All obstructions shall be removed, and the
lines from one manhole to the next shall exhibit a fully circular pattern. Lines which do
not exhibit a true line and grade or have structural defects shall be corrected to meet
specifications.
2. The Engineer, Owner, or SRU inspector may require inspection by television camera
(CCTV) of any sewer lines or laterals. The CCTV equipment must provide adequate
light for the camera and be of high video quality (including the video tapes or DVD) to
properly show the inside of the pipe. Each line and lateral must be marked with an
identifying number and shown on the video tape or DVD and a log of any problems
found, along with the line number and footage and/or IateraI number must be included
with the video tapes or DVD.
D. Leakage
1. Leakage tests shall be conducted on a schedule agreed upon by the Engineer and Owner.
2. Engineer and Owner's designated representative must be on site for all required testing.
3. Low pressure air testing shall be used to test for leakage in sewer lines and laterals. The
test shall be in accordance with ASTM F 1417 as modified herein.
4. The pipeline is considered acceptable if when tested at a pressure of 4.0 psi (or greater
than the average back pressure of any groundwater that may submerge the pipe) the
section under test does not lose more than 0.5 psig within the allotted test time. Refer to
Table: 1 for time specifications.

* Consult with pipe manufacturer for maximum test pressure for pipe size greater than 36
in. in diameter.
5. This low pressure air test may be dangerous to personnel if, through lack of
understanding or carelessness, a line is over pressurized or plugs/caps are installed or
restrained improperly. It is extremely important that the various plugs be properly
installed to prevent the sudden expulsion of a poorly installed or partially inflated plug.
Observe the following minimum safety precautions:
a. No one shall be allowed in the manhole during testing.
b. Contractor to install and retrain all caps and plugs securely.
c. When the lines are tested, it is mandatory that all caps and plugs be braced as an
added safety factor.
d. Do no over pressurize the lines. Do not exceed 9.0 psig.
e. A regulator or relief valve set no higher than 9.0 psi shall be included on all
pressurizing equipment.
E. Deflection Test (for PVC pipe)
1. No sooner than thirty (30) days after final backfill installation, each section of PVC pipe
shall be checked for vertical deflection using an electronic deflectometer or a rigid "Go-
No/Go" device.
2. Vertical deflection shall not exceed 5% of the inside pipe diameter (7.42 inch diameter
mandrel required for 8" pipe).
3. Pipe exceeding the allowable limit shall be repaired and retested. Engineer or the
engineer's designated representative must be on site for all required testing. City
inspection of the test is required.
F. Manhole Vacuum Test
1. All testing shall be performed in the presence of the engineer or designated representative
and SRU inspector.

2. Every manhole shall be checked for air tightness prior to setting of the manhole ring and
cover. All manholes, whether with precast base sections or poured -in -place base, shall be
vacuum tested. All lift holes shall be plugged with a non -shrink grout.
3. All pipes entering or leaving the manhole shall be plugged, taking care to securely brace
the plug from being drawn into the manhole during the test.
4. Notify the Engineer/Owner's representative and SRU inspector must be present for the
test, notify Engineer/Owner 48 hours prior to conducting the test.
a. The vacuum equipment test head shall be placed at the inside of the top of the cone
section, the seal inflated in accordance with the manufacture's recommendations.
b. A vacuum of 10-inches of mercury shall be drawn and the vacuum pump shut off.
c. With the valves closed, the time shall be measured for the vacuum to drop to 9-
inches of mercury.
d. The test time shall be correlated to the manhole as follows:
Manhole Diameter Allowable Time:
48" 60 seconds
60" 75 seconds
e. If the manhole fails the initial test, necessary repairs shall be made at the
contractor's expense with an approved non -shrink grout on the outside of the
manhole while the vacuum is being drawn.
f. The re -testing and repairing schedule cycle shall continue until the manhole passes
the test.
G. Leaks and loss in test pressure constitute defects that must be repaired.
H. Replace leaking piping using new materials, and repeat testing until leakage is within
allowances specified.
3.10 CLEANING
A. Clean dirt and superfluous material from interior of piping. Flush with potable water.
