Paul R. Noland WWTP Electrical Study
Introduction
A. The purpose of this study is to evaluate the 12.47 kilo -volt and the 480 volt (3) three phase
electrical equipment at the Paul R. Noland Wastewater Treatment Plant as it relates to the
condition of the equipment and the availability of replacement parts for equipment prior to
or at the time of failure.
B. Then scope of this project will include electrical 12.47 kV equipment, distribution, 480 volt
(3) three phase, distribution, Motor Control Centers, switchboards, panelboards, Busways
and special switches. The evaluation will include an inventory of the existing equipment,
approximate age and condition of the electrical equipment for either replacement or parts
of the electrical system to have on hand or a plan in place for response to equipment
failures as they occur. The site electrical distribution system is shown on Figure 1, and the
electrical one line diagram is shown on Figure 1A.
Existina 12.47 kV Distribution System
The 12.47 kV Distribution System is comprised of both overhead and underground
facilities. The overhead portion of the electrical system is visible and in good condition.
Replacement parts are common and require short lead times to acquire. No improvements
are recommended at this time.
The 12.47 kV underground facilities consist of buried cable, switchgear, pad mount
transformers and associated hardware. The cable has a concentric neutral with an outer
sheath. This type of cable typically has a lifespan of 40 years. Since the plant is
approximately 40 years old, the cable is near the end of its normal life. Buried cables can
be spliced or replaced. Underground cable is common and requires a relatively short lead
time to acquire. We recommend replacing these underground cables with a scheduled
upgrade/improvement to the facility.
There are four locations where 15 kV switchgear is utilized. The main unit is next to the
old Primary Influent Building. This unit has switches that are not operated and it contains
a live buss. A live buss configuration is dangerous since limited protection is provided
between energized parts and the employer. Various switches and handles stick due to its
age and non-use. A second unit similar to the first is near the original Operations Building.
It has the same conditions as the first with some exceptions. The internal fuses are
bypassed and several switches do not work at all. These units are not a common brand
and will be extremely difficult to obtain any replacement parts. Due to the units being
unsafe to operate, we recommend changing both of these out to a newer style without a
live buss.
The third unit was installed in 2006. It is located near the first and next to T101. It has the
newer dead front design which provides additional protection from energized parts. It
appears in good condition. Replacement parts are still available for this unit.
1
The forth location consists of two pad mount units. They are located in front of the Aeration
Basins. These units also utilize the newer dead front design. They appear to have been
installed as part of the upgrade to the old Chlorination Building. They also appear to be in
good condition. Replacement parts are still available for these units.
New 15 kV switchgear is similar to those in front of the Aeriation Basin Building. The new
units are dead front which provide additional protection from electric shock and arc flash.
New switchgear comes in a variety of switching and fused protection schemes. It is
recommended that the old unit near the old Primary Influent Building be replaced with a
PME-9 style unit. A four way 15 kV sectionalizing cabinet with dead front connections is
recommended in front of the new switchgear. This will aid in splitting the 12.47 kV lines.
The estimate for this cabinet is $4,000 with an additional $2,000 for labor. It is
recommended to use a PME-9 style unit to replace the switchgear near the old Operations
Building. The PME-9 has an estimated cost of $32,000 with an additional $8,000 for labor
per unit. We would recommend replacing this equipment within the next year.
Existing 12.47 kV Pad Mount Transformers
There are ten pad mount transformers of various ages at the plant. The newest units are
at the Ozone Building, T101, near the Primary Influent Buildings and TX -5 near the old
Operations Building. They appear to be on good condition. Transformers are not items
that typically have replacement parts. The most cost effective method is to change out the
entire transformer. Pad mount transformers are easy to locate.
The oldest transformers are located in pairs; one is for the Aeration Basins, one for the
Primary Influent and one for the Blower Building. All of these are old GE transformers with
built in high -side load interrupter switches and low -side breakers. No manufacturing date
is given on their nameplates. These transformers are still in operation but their age is
unknown. Their high -side switches either do not work or do not work well. This is the switch
that is used to de -energize the transformer, These types of transformers are very rarely
seen today.
One of the transformers near the old Primary Influent Building has developed a small oil
leak. The cabinets are rusting through. (See Figure 4A, upper right picture) This location
utilizes an underground feed into the buildings Motor Control Centers. It is recommended
to replace this pair of transformers. These are recommended for replacement.
The other two units have overhead raceways that supply the switchboards. These units
do not show any visible sign of rust at this time. Since they appear to be the same age as
the first pair and a transformers typical life span is approximately 40 years, they are also
recommended for replacement.
There are two transformers that supply the Ozone Building. They appear to be in good
shape. There is a clearance violation on the southernmost unit. It should have a minimum
of ten feet in front of the doors. It has four feet nine inches to the next transformer. This
is a safety clearance violation. We recommend rotating the transformer 90 degrees.
This cannot be done energized. The same foundation can be used but new secondary
conductor may be required to feed the switchboard. Care must be taken not to bend the
underground cables to sharply or the insulation can be ruined.
New pad mount transformers are similar to those in front of the Ozone Building. We would
recommend replacing like size transformers. For instance, AB -1 and AB -2 are 1500 kVA
each. Replacements for these would be the same voltage and kVA size. The estimated
cost to replace a 1500 kVA transformer is $30,000 per unit with an additional $8,000 for
labor. The estimated cost to replace a 500 kVA transformer is $12,000 per unit with an
additional $5,000 for labor. We would recommend replacing this equipment within the next
five years.
Existing 480 Volt Electrical Distribution Systems
A. Original Operations Building (OPS Bldg).
The Operations Building was part of the original Wastewater Treatment Plant built
sometime around 1968 to 1978. The building is mostly used for equipment storage
and materials used in the process. Most of the electrical equipment has been
abandoned and de -energized but the main switchgear located in the basement is still
in service, this equipment is at least 40 years old and nearing the end of safe operation.
The Operations Building switchboard consists of three sections of Square -D, Saflex
Fusible Switches, the main switch is a 2000 amp fusible switch. This switchboard is
fed from the 12.5 kV switchgear and transformer just south of the old Operations
Building and labeled, Load Interrupter -2.
This type of gear does not have any metering for voltage or ampere reading to the
operator only on and off switches, over time the mechanisms can become corroded
and rusted decreasing the safety at shut-off and to re-energize. There appears to be
very little load being used at this time. This switchgear is located in a very damp
environment, with no lighting.
Depending on the future use of the Operations Building, this service and equipment
could be replaced with a smaller ampere service and panelboard. One of the branch
fusible switches in this gear serves power to a 3 -section Motor Control Center located
on the main floor, labeled MCC -1.
MCC -1 is a Siemens Motor Control Center Model 90. It appears that the panelboard
and transformer located in the third section are the only load, and a breaker in the
second section that feeds a remote starter panel labeled Sump Pump Control Panel.
MCC -1 is in fair condition. Most of the equipment in this MCC is not in use, and does
not pose a great deal of hazard to the plant operations. (See figure 2).
B. Newer Influent Pump Station
The newer Influent Pump Station was added on to the Noland WWTP sometime
around 2006-2008. This building is fed from transformer labeled T101 that is a 750
kVA 12.47 kV primary, 480 V 3 phase secondary receiving power from the Switchgear
101, S-1, S-3.
This outdoor switchgear and transformer provide power to the main switchboard -102-
main located in the Influent/Headworks Building, Switchboard -102 -Main consists of
four sections of gear. This first section houses the 1600 A frame, GE Power Break Il
Circuit Breaker with a 1200 amp rating plug. This breaker protects all equipment in this
building. In the top part of this section is the GE PQM II Power Quality Monitor.
3
The second section of this switchboard houses (18) 3 pole breakers of various
amperages for equipment and a 400A 3 pole breaker that serves power to MCC -101
and also has a built-in transient voltage surge suppressor in the lower portion of this
section, (See Figure 3 and Figure 3A.).
The third section of this switchboard houses (18) 3 pole breakers of various
amperages for equipment.
The fourth section of this switchboard houses (18) 3 pole breakers of various
amperages for equipment.
This switchboard is in excellent condition and replacement parts are still available.
MCC -101 that is fed from the Switchboard -102 -main section 2, 400A main breaker,
feeds main lugs only to section 1 of MCC -101. This Motor Control Center is a GE
Evolution series E9000, 600 amp rated horizontal bus and 300A vertical bus, 480 volt
3 phase 60 Hz. This MCC is also equipped with analog volt meter, amp meter and
transient voltage surge suppressor (TVSS).
MCC -101 has (6) total sections in the line-up. See Figure 3 & 3A for equipment
placement and space available for future use. This MCC is in excellent condition and
replacement parts are still available.

The Allen Bradley Custom Panels are shown on Figure 3 & 3A. They utilize Allen
Bradley 1336 Plus Variable Frequency Drives with Bypass Contactors in the event of
a drive failure. Two of the influent pumps 101 and 102 are controlled by this method
and fed from switchboard 102 -main section 3.
The remaining influent pump 103 is controlled by custom GE ASTAT-Plus solid-state
soft starter with bypass contactors, and fed from switchboard 102 -main section 4.
In summary, this equipment is in excellent condition, outside of the drive (VFD) issues
on RWW-P-101 which can be retrofitted with necessary modifications since it is a
custom built standalone enclosure.
The only power issue is, only one transformer serves this building and there is no
redundancy for a tie breaker switch in the event of transformer failure.
C. Original (Primary) Influent Pump Station No.1
The Original Primary Influent Pump Station No. 1 is part of the 1984-1985 Wastewater
Treatment Plant Improvements. This building along with the Generator Building is the
most important building to maintain electrical service to.
4
This building receives power from the 12.5 kV, primary power switchgear. This
switchgear receives power from the Ozarks Electric service pole just north and west
of the Administration Building. This load interrupter switchgear serves power at 12.5
kV to transformer PI -1 and transformer PI -2, both transformers are 500 kVA stepping
the voltage down to 480/277V, 3 Phase, 60 Hz.
Transformer PI -1 serves power to the normal power side of the 800A rated ASCO
Automatic Transfer Switch, and the load side of this switch serves power to MCC PI -
1, and the emergency side of this ATS receives emergency power from a 400 KW,
480/1227V, Cummins diesel powered generator. (See Figure 4 & 4A).
Transformer PI -2 serves power to MCC PI -2, the 400 KW diesel generator is set up to
provide power via a key interlock tie breaker switch located between MCC PI -1 and
MCC PI -2. This tie breaker switch allows the operator to energize both of the Motor
Control Centers, MCC -PI -1 and MCC -PI -2 in the event either one or both transformers
PI -1 and PI -2 fail or are without 12.5 kV power. The 400 KW generator is capable of
an output of 602 amps full load. The generator and ATS are in good condition.
MCC -PI -1 is a General Electric 8000 -line Motor Control Center built and
commissioned into service sometime around 1985. This MCC consists of four sections
of gear. The main breaker is an 800A General Electric key interlock breaker. This
breaker is no longer available and is crucial to the operation of this Motor Control
Center, and the loads associated with this gear for normal operation. (See Figure 4 &
4A).
MCC -PI -2 is a General Electric 8000 -line Motor Control Center built and
commissioned into service sometime around 1985. This MCC consists of five sections
of gear with a 600A keyed interlock switch adjoining MCC PI -1 and MCC PI -2 enabling
the two to be tied together during outages. The main breaker located in section 1 is an
800A General Electric key interlock breaker. This breaker is no longer available and is
crucial to the operation of this Motor Control Center, and the loads associated with this
gear for normal operation. (See Figure 4 & 4A).
It is important to note MCC PI -2 serves power to the Administration Building allowing
this building to be energized from the 400 KW generator and automatic transfer switch
via the 600A tie breaker in the event of power failure.
The General Electric 8000 -line is one of the most commonly found GE low voltage
Motor Control Centers in operation in the United States today and is easily
distinguishable by its signature rounded red handle operators. GE 8000 low voltage
Motor Control Centers typically have a very long life span.
The MCC structures and internal buswork almost always outlive the life of the
individual buckets, which are prone to breakdowns and obsolescence.
There are companies that recondition direct replacement MCC buckets for the GE
8000 -line Motor Control Center, and they can upgrade to an intelligent motor control
such as Devicenet, Profinet, or Ethernet.
Generally, the issues around this type of option is space for VFD's and bypass
contactors, and you still have a 35 -year-old MCC structure and internal bus.
Another issue for rebuilt and reconditioned equipment is backordering and long lead
times for hard to find manufacturer discontinued equipment.
Options for upgrading MCC PI -1 and MCC PI -2 are as follows:
Option 1_: Retaining the existing MCC's by retrofitting and reconditioning the
individual buckets; as in the case of RWW-P-01-1-1, the breaker in section 2 of
MCC PI -1 serves power to 3 sections of custom Allen Bradley, VFD with bypass
contactor located adjacent to the MCC. This method allows for starters and
controls to be located outside the MCC and utilize the main pump breaker as the
source of power. This option can provide for a new up to date motor starter and
controls but still leaves you at the mercy of the older pump breaker.
Option 2: Would be to replace the existing Motor Control Center with new available
MCC sections to accommodate VFD's, full voltage starters, solid-state starters and
intelligent controls such as Devicenet, Profinet, or Ethernet. This option would have
to be done rather quickly to allow for whole MCC's to be replaced at one time to
keep plant operations going.
Another approach would be, if space allowed, new MCC to be energized and
placed near the old MCC and move loads one at a time to new MCC sections. This
method would be the most expensive option but in the long run all new equipment
would be in place in the end and could be designed to meet Arc Flash
requirements.
D. Aeration Basin Building
The Aeration Basin structure is part of the 1984-1985 Wastewater Treatment Plant
Improvements and is a major part of the plant operations. The electrical service at this
structure serves power to other facilities, buildings and structures.
The aeration facilities receive 12.5 kV power underground from the 12.5 kV primary
power switchgear near the 400 KW generator, 12.5 kV primary power underground is
then fed into two separate S&C switches, each of these S&C switches feed
transformers TX -AB -1 and TX -AB -2. They are 1500 kVA and are equipped with a
switch on the secondary side that feeds 480/277V to switchboard AB -1 and
switchboard AB -2 with a 1600A tie breaker between them. (See Figures 1, 1A, 5, 5A
& 5B).
Low voltage switches LV -AB -1 And LV -AB -2 are disconnect switches built on to
transformers TX -AB -1 and TX -AB -2, they serve power through to switchboard AB -1
and AB -2 via 2000 amp service entrance Busway. The age of this equipment is not as
reliable after years of service due to load, stress, U.V., and weather. The Busway
feeding AB -2 has been replaced at some time. Busway should be checked periodically
for torque at each joint due to temperature changes. The recommendation for this
service entrance would be to replace both service entrance feed with conduit and
conductors, with no splices in cables, which would reduce the number of connections
to two per service entrance. In addition, switchboard AB -1, AB -2 and the tie breaker
could be located outside just north of the transformers in a weather proof enclosure
eliminating the need for LV -AB -1 and LV -AB -2 and utilize the existing switchboard
location to interconnect associated equipment.
0
Switchboard AB -1, AB -2 and the tie breaker switch allows this structure to be fed from
either transformer TX -AB -1, or TX -AB -2. This switchboard is critical to the operation
of the plant. It serves power to MCC AB -1, MCC AB -2, MCC AB -3, and MCC AB -4
located in the Aeration Building and the two MCC FB -1 and MCC FB -2 located at the
Filter Building.
This switchboard is a GE AV -line switchboard, 3 phase 480V, 3 wire, 60 Hz, 2000
amp, 35,000 amp short circuit rating. (See Figures 5 & 5A). This type of switchboard
is no longer manufactured by General Electric. There are however, companies that
specialize in refurbished breakers and mounting equipment but they will not have the
Arc Flash mitigation used today. In addition, new breakers would be equipped with full
range of overcurrent and ground fault protective functions, along with advanced
metering communications and protective relaying options. In summary, this
switchboard is heavily relied upon for service and would definitely be a part of the
electrical to replace with new equipment.
The following Motor Control Centers MCC AB -1, AB -2, AB -3 and AB -4 are located in
the Aeration Electrical Room serving the various motors, pumps and equipment within
this structure.
The MCC's are GE 8000 -line sections put into service sometime during the
Wastewater Treatment Plant Improvements 1984-1985. As mentioned previously this
line of gear is the most common Motor Control Center in operation and typically has a
very long life for the structure and internal bus that outlives the individual buckets.
Since the manufacture of this gear, MCC's have become more compact in design
allowing different types of starters, I.E.C. overloads, VFD's, solid-state starters to be
installed in buckets of smaller stature. In addition, the newer MCC's allow for and can
be constructed with newer Arc Flash requirements.
Many of the existing buckets have been taken out of service except for the breaker
protecting that particular bucket and used to feed an open chassis VFD as shown on
Figure 5. This approach works well if there is enough wall space, the only drawback is
the conduit and conductors required to go to and from the MCC and drives.
One of the advantages when replacing the MCC's is that they can be isolated and shut
off during changeover without de -energizing all four MCC's at once, enabling most of
the operations to continue. Costs for replacement of each MCC is between $40,000
and $60,000 depending on types of motor starting and control. We would recommend
replacing these units in the near future.
When replacing the main tie breaker switchgear, a portable generator or more than
one can be brought in and temporarily feed the individual existing MCC's to maintain
operation of the existing Aeration Building and Filter Building by connecting to their
main -lug -only (MLO) incoming line buckets. This approach has to be a coordinated
effort with the new switchgear on site and ready to remove old equipment and install
the new equipment in a timely fashion. Typical costs for switchboards in the
arrangement at the Aeration Building, 2000 amp main breaker sections with ground
fault protection are in the $25,000 to $30,000 dollars not including switchboard
7
instruments. Additional 800A and 300A breakers are in-between $3,500 and $6,000
dollars.
E. Ozone Equipment Building (Former Chlorination Building)
The Ozone Building is part of the 1984-1985 Wastewater Treatment Plant
Improvements. This building was originally used for chlorination process, U.V. and
finally ozone generation.
This building has undergone several renovations. Much of the existing electrical
equipment is still in place but not utilized with the addition of and need for more power
at this facility.
The original building is fed from a breaker located in MCC AB -3 Aeration Building and
is still in service. This breaker feeds CBPP, which at some time was replaced with a
newer SQ -D 480 V, 3 phase, panel.
With the addition of the U.V. system, power needs increased and two (2) new
transformers were installed just west of the building transformer No.1 and No. 2
(East/West) and being fed from the 12.5 kV switches located at the Aeration Basin
Building. These two transformers are 500 kVA. (See Figure 6 and Figure 7).
The two transformers provide power to DP -1 General Electric Spectra Series Outdoor
Switchboard. This switchboard is a split bus with two 600A main keyed interlock
breakers and one 600A keyed interlock tie breaker to allow the entire panel to be fed
from the transformer No.1 or No.2. This panel has only one space available. In
addition, the feeders to the two U.V. disconnects are still in place but taped off and not
used. The new ozone equipment was added and additional breaker panels were
added to serve the new ozone equipment detailed on Figure 6 & 6A. All of the newer
equipment is current and breakers available.
The DP -1 would need to be replaced if the City would want to or need to utilize the
decommissioned U.V. Disinfection for emergency use, without having to land the
existing feeders to the DP -2 and DP -3 breakers that currently feed ozone equipment.
All of the newer breakers, panels, disconnects, and transformers are in excellent
condition.
F. Former Chlorine Contact Basin and Post Aeration Basin
The Post Aeration Basin is part of the 1984-1985 Wastewater Treatment Plant
Improvements. This structure has had additions and improvements and all of the
electrical equipment is in excellent condition.
This structure receives power from two locations. The Ozone Building DP -1 feeds
distribution panel DP -4 for off gas destruct units and MCP -08 as shown on Figure 7.
In addition, the abandoned Trojan U.V. system is still in place and operational. The
existing feeds are underground to DP -1.
The structure also receives power from the Filter Building MCC's FBA and FB -2. The
post aeration aerators and low voltage equipment are fed from MCC's FBA and FB -
2.
V*.i
G. Administration Building and Equipment Storage Building
The Administration Building receives its power from the original Primary Influent Pump
Station No.1 which is also backed by the 400 KW generator. There is a 200 amp, 3
pole, 480V disconnect that serves power to a 112.5 kVA, 120/208V, 3 phase step
down transformer, General Electric Model 9123 G 3875 with 5% impedance, dry type.
From the transformer, a Nema size 5 contactor with bypass feeds the lighting panels
ADLP-1, ADLP-2 and EMLP. This equipment is still serviceable and in good condition.
(See Figure 8).
The Equipment Storage Building receives its power from the Filter Building MCC FB -
1 Section 3 labeled ESPP, Equipment Storage Power Panel. This is a GE 480 volt, 3
Phase, 80 amp main, NHB panel. The Breakers in this panel are discontinued but can
be purchased used, and in some cases as new surplus, costs per breaker can be as
much as $200.00 each. (See Figure 8).
H. Filter Building
The Filter Building is part of the 1984-1985 Wastewater Treatment Plant
Improvements and receives power from the switchboard AB -1 & AB -2 located in the
Aeration Basin Electrical Room. There is a 300A breaker in AB -1 & AB -2 that feeds
MCC FB -1 and MCC FB -2. In addition, this allows either Motor Control Center to have
its load on switchboard AB -1, AB -2 with the breaker closed on one of the transformers
located at the Aeration Basin.
The MCC FB -1 and MCC FB -2 are GE 8000 -line Motor Control Center. MCC FB -1 has
4 Sections with a 300A main breaker in Section 1 and MCC FB -2 has 3 Sections with
a 300A main breaker in Section 1. This equipment is in fair condition. Refurbished or
reconditioned buckets are still available but have long lead times and are still
expensive, if they can be found.
To replace MCC FB -1 and MCC FB -2 would not be as difficult if the Filter Building
equipment could be operated off one MCC at a time. Some temporary conductors may
need to be installed to maintain some of the operations during changeover. In this
instance, a new MCC would be more economical than to refurbish this equipment.
Typical costs for these MCC's are $16,000 to $24,000 per MCC. (See Figure 9 & 9A).
There is a new 4801277V panel labeled PP -FB that is a GE A Series II with a built-in
transient voltage surge suppressor. This panel is of current construction and breakers
and parts are still available.
Solids Dewatering Building
The Solids Dewatering Building was built sometime around 2004 Wastewater
Treatment Plant Improvements. This building is fed power from the Blower Building
switchboard B-1 and B-2. Each switchboard has a 600A, 3 pole breaker that serves
power to MCC -201 and MCC -202 individually. Switchboard B-1 and B-2 are fed from
separate transformers at the Blower Building with a 1600A tie breaker switch to shift
all load to one transformer if necessary. In addition, the Motor Control Centers have
the capability of running off one of the service feeders by utilizing the 600A tie breaker
switch between MCC -201 and MCC -202 in the event one of the 600A main breakers
in switchboard B-1 or B-2 failed. (See Figures 10,10A, and 12,12A).
69
The Motor Control Centers MCC -201 and MCC -202 are of the newer GE Evolution
Series E9000 and are of current construction. Parts such as breakers, pilot lights,
switches starters are still available. For the most part MCC -201 and MCC -202 are
breakers in tandem buckets that feed remote starters and controls. The equipment is
in excellent condition and should provide good service for several years.
J. Digested Sludge Pump Station
The Digested Sludge Pump Station is part of the 1984-1985 Wastewater Treatment
Plant Improvements. This building receives power from the Blower Building
switchboards B-1 and B-2. Each switchboard is equipped with a 400A, 3 pole breaker.
Switchboard B-1 400A breaker feeds MCC DS -1 400A main in Section 2. Switchboard
B-2 400A breaker feeds MCC DS -2 400A main in Section 1. There is not a tie breaker
switch between the two Motor Control Centers,
MCC DS -1 has 4 total Sections of MCC. The two original sections 1 and 2 are GE
8000 -line gear approximately 35 years old and they contain the Digester Sludge
Pumps designated P-07-18-1 and P-07-18-2 starters, still in service. Sections 3 and 4
are newer sections of MCC GE 8000 -line gear. They were added for WAS Pumps P-
401 and P-402_ In addition, there are two larger starters in Section 3 and 4 shut off
and not labeled but are possibly the original digester feed pumps. Waste activated
sludge pumps designated as WAS -P401, WAS -P402 are breakers only in the MCC
sections and serve power to the remote wall mounted Allen Bradley custom VFD
cabinets with bypass contactors.
MCC DC -2 has 2 total sections of MCC and are original GE 8000 -line gear
approximately 35 years old. Section 1 contains the 400A main breaker and digester
sludge pump P-07-18-3. Section, 2 contains the breaker that feeds WAS -P-403 and
VFD with bypass contactor. (See Figure 11). The Digester Sludge Pump buckets are
probably the most crucial as far as replacing starters is considered. If space in the
Electrical Room allowed, standalone combination starters would be considered.
The Motor Control Centers could be removed and two 400A distribution panels with
breakers put in their place to feed the remote panel starters as in the case of the waste
activated sludge pumps, In addition, a new section of MCC could be installed to feed
the existing supply fan and any future size 1 starters needed. This would eliminate the
issues associated with the discontinuation of Motor Control Center models.
Typically, distribution breaker panels are less expensive than Motor Control Centers
K. Blower Building
The Blower Building is part of the 1984-1985 Wastewater Treatment Plant
Improvements and is a major part of the plant operations. The electrical service at this
location serves power to other facilities, buildings, and structures.
The Blower Building receives 12.5 kV power underground from the 12.5 kV primary
power switchgear near the 400 KW generator at the Primary Influent Building, from
there 12.5 kV underground to the primary load interrupter -2 at the old Operations
Building and then to TX -BI -P and TX -B2 -P primary switches bolted to transformers
TX -B1 and TX -82. (See Figure 1, 1A, 4, 4A, 12 and 12A).
Low voltage switches labeled LV -131 and LV -132 are bused and bolted to transformers
TX -131 and TX -132. The low voltage 2000 amp switches utilize overhead and weather
10
proof 2000 amp service entrance Busway to bring power to switchboard B-1 and B-2.
The age of this Busway is not as reliable after years of service due to load stress, U.V.
and weather. Busway should be checked visually on a regular basis. Splice joints are
especially prone to corrosion damage and joint failure. Even after joints dry out after
being contaminated, the corrosive effects continue.
Maintenance should always test connections for proper torque. Arcing can occur
between the plate surfaces due to poor connections or after water or other liquids enter
the spaces between loose plate connections. This type of damage can increase the
contact resistance of the joints and eventually cause overheating or worse arcing
faults. Infrared thermography can detect potential failures for repair before an event
causing a building outage. The recommendation for this service entrance would be
conduit and conductors in place of Busway. It should be noted that the Busway at this
location is mounted vertically and sealed which prevents many issues when compared
to horizontal mounted Busway.
The two switchboards fed from each Busway just inside the Electrical Room are GE
AV -line switchboard. Switchboard B-1 480Y/277 volt, 3 Phase, 4 wire, 60 Hz, 2000
amp supply, 2000 amp neutral with short circuit rating 30,000 RMS SYM, amps at 480
volt. The Switchboard B-2 is the same rated gear.
Switchboard B-1 contains one 2000 amp main breaker that is a GE power break keyed
interlock style, This breaker is located in Section 1, and the bottom half of this section
contains two additional breakers, a 400A 3 pole designated for MCC DS -1 in the
Digested Sludge Pump Station, and a 600A breaker designated to MCC -201 Sludge
Dewatering Building. Section 2 of switchboard B-1 contains a 1600 amp tie breaker
that is a GE power break keyed interlock style to connect switchboard B-1 to
switchboard B-2. Located in the bottom half of Section 2 a GE 1600A main breaker,
GE power break that serves MCC -B-1.
Switchboard B-2 contains one 2000 amp main breaker that is a GE power break keyed
interlock style. This breaker is located in the upper half of Section 1, and the bottom
half of this section is empty. Section 2 of switchboard B-2 is a panelboard section, and
contains a 400A, 3 pole breaker that serves MCC B-3 and a 400A breaker that serves
MCC DS -2 in the Digested Sludge Pump Station. A 1200A GE Versa trip breaker
serves MCC B-2 Blower Building, and a 600A breaker that serves MCC 202 Sludge
Dewatering Building.
MCC B-1 contains 8 sections of Motor Control Center and (3) three 300 HP reduced
voltage autotransformer starters and (1) one 15 HP RVATS.
MCC B-2 contains 7 sections of Motor Control Center and (2) two 300 HP reduced
voltage autotransformer starters and (2) two 15 HP RVATS.
MCC B-3 contains 2 sections of Motor Control Center and (2) two 75 HP full voltage
starters and (2) two 3 HP full voltage starters, and (1) one 30A 2 pole breaker for low
voltage 120/240V power.
11
The three MCC are all GE 8000 -line put into service sometime in 1984-1985. The
motor starters are 35 years old and most parts are not manufactured in this
configuration, but there are reconditioned parts available.

The central part of this service is in switchboard B-1 and B-2 because the switchboards
serve other facilities. The recommendation for this building would be to either upgrade
both switchboards and breakers with Arc Flash attenuation, or at a minimum stock
reconditioned breakers as follows:
Switchboard B-1, B-2 Blower Building Inventory of key main breakers
(2) 2000A GE Power Break Keyed Interlock (Mains)
(1) 1600A GE Power Keyed Break Interlock Tie Breaker
12
(1) 1600A GE Power Break Main
(3) 400A GE Main
(1) 1200A GE Main
(2) 600A GE Main
The switchboard located at the Aeration Basin Building contains the following
inventory of key main breakers:
(2) 2000A GE Power Break Keyed Interlock (Mains)
(1) 1600A GE Power Keyed Break Interlock Tie Breaker
(4) 800A GE Versa Trip Mains
(2) 400A GE Mains with 300A Trip Modules
Reconditioned breakers to keep on hand if replacement is not an option:
(1) 2000A GE Power Break Keyed Interlock
(1) 1600A GE Power Break Keyed Interlock
(1) 800A GE Versa Trip
(1) 600A GE Versa Trip
(1) 400A GE Versa Trip
The two main locations with this style of switchboard would allow the City to keep on
hand a minimal amount of breakers.
The 2000 amp GE power break with key interlock are the most expensive and this
plant has four of them. Approximate cost for a reconditioned breaker is $16,000 with
a 1 year warranty. Sometimes new surplus can be found but is often times $20,000 to
$30,000. Extreme caution should be exercised to order the correct rating for this type
of breakers. Some of them utilize a 100% trip or 80% trip.
Replacing the switchgear is the most expensive option but allows for solid-state
circuitry as well as current Arc Flash requirements to be met.

Paul R. Noland WWTP Supplement
The 12.47 kV supplies equipment for the entire plant. Replacing and upgrading will
require coordination. There will be times that various locations will have to be de -
energized for equipment to be changed out. Some switching through the 480 volt
switchboards may be utilized to keep operations energized during construction. The
budgetary cost for replacement would include the following equipment and labor cost
combined.
15 kV 4/0 AWG URD -AL Cable (2000')
$20,000
15 kV #2 AWG URD -AL Cable (700')

The option of upgrading the 480 volt electrical services is the most expensive option, but
the most reliable and compliant method for the Noland WWTP.
Our recommendation would be to stage the main services for the original (Primary) Influent
Pump Station, Aeration Basin Building, Blower Building, the original Operations Building
and the Ozone Equipment Building.
The original Primary Influent Pump Station should be addressed first since it is the main
service for all other buildings and structures through the 12.5 kVA Primary Power
Switching Station. The 480v electrical design would include two (2) new Motor Control
Centers and a tie Breaker as it is currently designed. The building and electrical is shown
on Page 4, Part C, Figure 4 and 4A.
The City of Fayetteville at some point in design would choose the type of motor starters
and controls for the existing pumps and equipment fed from these two (2) Motor Control
Centers. For this recommendation, we would estimate costs for variable frequency drives
for the larger pumps and reduced voltage solid state starters for the smaller motors and
pumps.
The existing MCC PI -1 and MCC PI -2 are bused together with a 600A tie Breaker keyed
interlock with the two 800A main Breakers. The issue with this equipment is space and
trying to fit the new equipment in this same layout. Our recommendation would be to utilize
sub -feed Breakers to custom built VFD cabinets for the Influent Pumps and all other
equipment fed from the Motor Control Centers in integral buckets. The most important part
of staging this equipment replacement would be to have all equipment on hand, and sub -
feed panels for Influent Pumps installed and ready for connection to the new gear.
The original Primary Influent Building MCC's can be replaced all at once or one at a time
using the 400 KW generator for temporary power to maintain operations at this building.
The budgetary cost for replacement would include the following equipment and labor costs
combined.
MCC PI -1
• Main Breaker with keyed interlock
• Two custom built with variable frequency drives with bypass contactors in
stand-alone enclosures
• Transient voltage surge suppressors
• Three Clarifier starters
• Three spare starters
• Electronic amp meter and volt meters SCADA capable
• Three main Breakers for VFD cabinets
Base MCC Main $10,000
VFD's $30,000
TVSS $5,000
Starters $10,200
Electronic Metering $3,500
Sub -Breakers $6,000
$64,700
Misc. Labor
and temporary power • 20,00(7
$84,700
MCC PI -2
• Three custom built with variable frequency drives with bypass contactors in
stand-alone enclosures
• Transient voltage surge suppressors
• Three Clarifier starters
• Three size 1 starters for misc. equipment
• Five Breakers for misc. equipment
• Three main Breakers for VFD cabinets

The main transformers at this location as shown in Figure 4 are equipped with an 800A
main Breaker bolted and bussed to the transformer secondary side to feed the two (2)
MCC PI -1 and PI -2 main Breakers inside the building. It would not be necessary to have
these in place since there are mains inside, unless isolation of the MCC is desirable. By
eliminating these main switches, Breakers a cost savings of approximately $18,000 could
be saved.
The Aeration Basin Building is the next location that should have equipment replaced and
or modified for reliable operation. This building and electrical is shown on Page 6, Part D,
Figure 5 and 5A.
The 480 volt electrical design would include the main building switchboard and four (4)
Motor Control Centers integral to this building. There are two (2) Motor Control Centers
located at the Filter Building.
The City of Fayetteville at some point in design would choose the type of motor starters
and controls best suited for this part of the process. For this building we would recommend
replacing the bus duct from the secondary side of the two transformers AB -1 and AB -2
with new conduit and conductors to a new switchboard located in the building. From the
switchboard MCC's AB -1, AB -2, AB -3, and AB -4 should be replaced. In addition, the two
(2) MCC's FB -1 and FB -2 located at the Filter Building.
A portable generator or generators may be necessary to keep some of the equipment
operational during renovation of the switchboard and the individual Motor Control Centers.
The most important part of staging this equipment would be to have all new equipment on
hand and ready for changeover.
The budgetary cost for replacement would include the following equipment and labor costs
combined.
Conduit and Conductors from T -AB -1 and T -AB -2 to switchboard AB -1 and AB -2.
2000A conduit and conductors per linear foot, $130.00 with 5 runs each
