Re: Detention Pond - Wal-Mart Expansion
Jacksonville, North Carolina
Dear Mr. Guerin:
Post Office Box 1685
409 Johnson Blvd.
Jacksonville, N.C. 28541
Please find enclosed herewith an "Operation and Maintenance Plan"
that we need for you to sign concerning the above referenced
project.
As we discussed on the phone, the existing detention pond that
serves the Wal-Mart Store was designed, permitted and approved
for approximately thirty thousand square feet (30,0001) of
surface area. When applications were submitted for the. expansion
of the Wal-Mart store the State of North Carolina recognized the
error that the detention pond was original designed to small.
This was made in error by the designing engineer and the State of
North Carolina. Wal-Mart Stores is paying for the expansion of
the detention pond. however, we will have to have the "Operation
and Maintenance Plan" signed and in hand prior 'to any approvals.
Should you have any questions concerning this matter, please feel
free to contact me.
Sincerely,
John L. Pierce

surface by raising or lowering the cord in the cord
snubber. Weights of special materials can be supplied
for use in chemicals.
SUPPORT BRACKET: A special support bracket
is bolted to the junction box (if used), otherwise it bolts
to the discharge pipe. Bracket has plastic cord snubber
that holds the switches at the required height. Cords
are spaced apart to prevent tangling.

Subject: WalMart Expansion -Jacksonville
Stormwater Project No. 921003
Onslow County
Based on an inspection of the site on February 10, 1993, I have determined that the drainage for
all the outparcels is split between the pond and the DOT ditches. The original estimate of 176,725 square
feet of impervious area to be subtracted from the total impervious area figure used to arrive at the
required surface area of the pond, must be cut in half to 88,363 square feet. Based on preliminary
calculations, the required surface area for a 4' deep pond would be 73,107 square feet. Of course, the
engineer must provide all calculations. The numbers I have presented here are for example only to help
the owners arrive at a financially sound decision regarding the upgrading of the pond.
A plan, supporting documentation, and calculations must be received by this Office in order to
begin a formal review for Certification of Compliance. Please keep me informed of the anticipated date
that this will occur. If you have any question, please do not hesitate to call me at [phone].

Storm water Project No. 921003
Onslow County
Dear John:
First I would like to apologize if you or your client were mislead in any way. The methodology
for reviewing plans is based on having all requested information in house before the review begins. It
was assumed that the original pond calculations were accurate and complete and all that was needed was
to verify that the pond could accept flow from a 30,000 square foot addition. That was the basis for the
conversation with you when it was stated that everything looked OK. When word was received that the
pond had been cleaned up and repaired at this Office's request, Linda inspected it, returned to the Office
and began her formal review. It was then that the error in pond sizing was discovered.
The original calculations called for the outparcels to be provided for at 100 % impervious. An
inspection at the site showed that the outparcels' runoff is not directed to the pond, rather it discharges
into the NCDOT ditches along Highway 17. This will allow 176,725 square feet of impervious surface
to be subtracted from the total used to determine the new pond size. Based on preliminary calculations,
that would reduce the required pond area at normal water level to 66,228 square feet, a little over twice
the present size.
The State will not direct the owner to enlarge the pond if no expansion takes place. However, if
expansion is requested, then the State must require that the pond be brought into compliance based on
the calculations for additional impervious area. This is no different than requiring a site that developed
prior to 1988 to be brought into compliance with current regulations when substantial changes are made
or if redevelopment occurs. You may want to look into the option of increasing the pond depth to reduce
required surface area.

Dear Mr. Cossel:
The Wilmington Regional Office received a Stormwater Submittal for the WalMart Expansion -
Jacksonville, N.C. on October 5, 1992. A preliminary review of that information has determined that
the submittal for the subject project is not complete.
An inspection of the pond by myself indicates that maintenance continues to be a problem. The
following items must be taken care of before the stormwater permit will be issued for the revised project:
1. The pond' slope from the paved area behind the smaller retail stores is severely eroded.
Please stabilize this area with vegetation able to withstand the sheet flow from the
asphalt area.
2. The catch basin in the same area is covered with trash. Please remove this trash on a
regular basis. The Operation and Maintenance Plan item #4 states that the culverts and
catch basins shall be "clear of silt and debris".
3. A shopping cart was observed to be lying in the water.
4. Please provide this Office with an updated plan of the pond. Some design changes were
approved by this Office, however, no revised plan was received.

5. A plastic corrugated pipe was observed to be draining into the pond from the northwest
slope. This pipe is not shown on any plans we have.
6. The pipe from the catch basin seems to be located too close to the pump. The plans show
the pipe to be entering the pond at the south end and the pipe is angled away from the
PUMP.

FEATURES T
HYDROMATIC
IN THE PUMP
HA
T HAVE MADE
A LEADER
INDUSTRY FOR YEARS
Hydromatic non -clog
submersible sewage pumps
include both enclosed and
recessed Impeller designs for
flexibility in sewage handling
application. Their cast iron
Impellers are designed to
handle 3-inch spherical solids
or larger with minimum
vibration and noise and may
be easily trimmed to meet
exact operating conditions.
Their oil -filled ball bearing
motors dissipate heat seven
Theioil-filled ball bearing
motors dissipate heat seven
times faster than air -filled
motors, so they run cooler
with better lubrication and are
easily serviced. Several
models are capable of running
dry without damage or the
need of water jackets for
installation in dry pit lift
stations. Consult
manufacturer for proper
selection.
A complete range of
explosion -proof models, tested
and third -party approved in
the U.S. for hazardous sump
locations, are available. These
designs incorporate increased
uniform wall thickness and
flame paths, flame -proof joints
and extra heavy duty power
and control cords, in addition
to the features listed below:
1. Double insulated and
compression fittPd power
and sensor cords sealed
into the cap with epoxy to
prevent water entry. Motor
leads are staggered in a
second epoxy -potted area
to halt wicking. Additional
chamber between seals
p;ovides extra sealing
security.
2. Two rows of heavy duty
ball bearings rigidly
support shaft and motor
rotor for reduced vibration
and wear and to absorb
thrust and radial loads.
3. Oil -filled motors provide
long life and quiet
operation through full
pumping range. Pure
dielectric insulating oil
lubricates motor and
bearings, effectively
dissipating heat. Heat
sensors detect abnormal
heat buildup in the stator
to prevent pump from
continuous operation at
high temperatures.
4. Tapered and keyed 303
stainless steel shafts
Recessed Impellers
Recessed impeller pumps
are the answer to high head/
low flow waste handling
situations, which require large
solids -handling capability.
They are capable of
continuous operation without
damage, have a low noise
level at any point on the
operating curve, and are not
subject to radial load
problems commonly
associated with operation
provide positive Impeller
drive and permit easy
removal for field service, if
required. Shafts are of
large diameter and
minimum overhang to
reduce shaft deflection and
prolong bearing and seal
life.
5. Dual mechanical, oil -
lubricated shaft seals.
Carbon and ceramic faced
seals mount in tandem to
double -protect the motor.
Seal sensor electrode
provides early, positive
detection of water in seal
chamber. Dual probes
supplied on explosion -
proofed designs.
6. Efficient two -vane enclosed
Impeller with pumpout
vanes prevents buildup of
stringy materials and grit in
seal and wear ring areas.
Bronze wear rings are
easily field -replaced.
7. 0-ring sealing of joints on
a beveled edge adds to
serviceability.
under high head/low flow
circumstances.
The recessed impeller
creates a liquid vortex in the
volute which directs sewage
and stringy materials through
the pump. Since the S impeller
vanes are out of the main flow
of sewage, stringy, fibrous
material that sometimes binds
the vanes or works up into the
seal area Is eliminated
without causing clogs.

11YDROMATIC SYSTEMS-
AMERICA'S BEST CHOICE
Wet Pit
Applications
"Pultruded Rail" (PR)
System
Hydromatic single rail lift stations
are ready for installation in concrete
sumps. These systems use a single,
non -corrosive FRP pultruded guide rail.
Here's how it works: The I-beam
shaped rail attaches to the aluminum
frame in the cover and to the discharge
elbow located In the sump bottom. No
base plate or carrier is required. A wire -
form stainless steel guide connector
attached to the pump discharge flange
guides the pump along the rail as it is
lowered or raised in the tank. When the
pump reaches the bottom of the rail,
rods cast into the hydraulic sealing
flange contact stainless steel arms
flanking the discharge elbow. The
downward sliding action of the rods
helps clean the arms of sewage debris
ind aligns the proven and patented
l +ydromatic sealing flange with the
Ascharge elbow flange. A small,
crescent -shaped peg on the bottom of
the elbow flange matches a
corresponding groove on the bottom of
the hydraulic sealing pump flange to
insure a flat, vertical connection and
spaces the two sealing faces apart to
prevent rustlocking.
When the pump is running, flow
pressure seals the diaphragm tightly
against the face of the discharge elbow
flange. When the pump shuts off, the
pressure drop eases the connection,
permitting the pump to be lifted with
no need to enter the wet well to part
metal -to -metal seals.
Refer to typical installation drawing
13004-000-1.
Available with pump models: S41VIN,
S4M, S4L, S4NX, S41VIX, S4LX, S4HRC,
S4NRC, S4MRC, S4LRC, S4HVX,
S4NVX, S4MVX and S4LVX.
11
"Dual Rail"
System
The Hydromatic Dual Rail System
utilizies two guide rails placed on
centerline with the pump unit Itself so
that when the pump is raised or
lowered, the guide rails (2" galvanized
or stainless steel pipe), serve only as a
guide without any binding. The guide -
rails are held by the baseplatel
discharge elbow assembly which sets
squarely on the bottom assuring
perfect alignment and a smooth flat
surface on which the pump rests.
Because the pump discharge flange
and the baseplateldischarge elbow
flange don't actually make contact,
preventing the possibility of unwanted
connection through corrosion, the
sealing of the two flannP faePn In
accomplished by the proven
Hydromatic hydraulic sealing
diaphragm. The same hydraulic sealing
diaphragm system that's used on the
pultruded rail system.
Refer to typical installation drawing
8510.
Available with pump models: S4F,
S4NX, S4MX, S4LX, S4NVX, S4MVX,
S4LVX, S6L, S6LX, SBL, SBLX, S12L and
S12LX.
Dry Pit
Installation
If your specification calls for a dry
pit application, Hydromatic pumps are
an excellent choice. Because our oil -
filled motors have Class F insulation
on the windings and overload heat
sensors, many of our submersibles are
capable of running dry without damage
for installation in a dry pit pumping
station.
In many cases, water jackets or
other special cooling systems are not
required. And, because the pumps are
submersible, flooding is never a
concern. The Hydromatic top pullout
design allows for easy inspection of
the rotating assembly -motor, shaft,
bearings, seals and Impeller. There is
no need to disturb the volute, suction
or discharge piping.
System
Components
Hydromatic is your single source
choice for complete lift stations,
Including the pumps, components, and
controls. All components are available
for installation In a concrete basin,
including our newly -designed door and
frame assemblies.
Aluminum frame and door with
aluminum tread plate and stainless
steel hinges and hardware is offered in
load ratings of 150 psf and 300 psf. A
standard size of 24" x 33" may be
installed on concrete basins for
simplex, duplex, or triplex pump
stations. Simply install side by side,
one per pump.
