CC 2017-10-10_09e Reservoir No 2 Standby Generator
MEMORANDUM
TO: CITY COUNCIL
FROM: BILL ROBESON, PUBLIC WORKS DIRECTOR
BY: SHANE TAYLOR, UTILITIES MANAGER
SUBJECT: CONSIDERATION OF AN APPROPRIATION OF FUNDS TO REPLACE
THE EMERGENCY STANDBY GENERATOR LOCATED AT
RESERVOIR NO. 2 ON HILLCREST DRIVE
DATE: OCTOBER 10, 2017
SUMMARY OF ACTION:
Approve funds to replace the generator at Reservoir No. 2.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
The replacement generator was not budgeted in FY 2017/18 and will reduce the
General Fund balance by $25,000.
RECOMMENDATION:
It is recommended the City Council approve an appropriation of $25,000 from the
unappropriated General Fund Balance to purchase a new standby generator and
automatic transfer switch for the Reservoir No. 2 communication building.
BACKGROUND:
The radio communication building located at Reservoir No. 2 on Hillcrest Drive provides
a secure location for the radios that serve the Arroyo Grande Police Department, Five
Cities Fire Authority, and the Public Works Department. Radio communication is vital to
daily operations. The existing standby generator is over 30 years old and no longer
works. A temporary trailer mounted generator with manual start has been in place since
the old generator stopped working during the February 2017 storm. It is vital during
power outages that this building has power to continue radio communications.
ANALYSIS OF ISSUES:
The existing propane powered standby generator at Reservoir No. 2 needs to be
replaced. A report was prepared by IRJ Engineers, Inc. detailing the requirements for
the replacement generator and automatic transfer switch. The report also identified
deficiencies in the current circuits that should also be corrected. The replacement and
upgrade of equipment will provide a long term solution to the current and future power
needs of this facility.

Re: City of Arroyo Grande
Reservoir 2 Emergency Generator Replacement
Letter Report
Dear J.J.:
We reviewed the existing emergency generator installation at Reservoir 2 on August 15, 2017.
The following report describes our observations and recommendations.
OBSERVATIONS
The existing system is served by a 100-amp, 120/240V, single-phase, three-wire service from
PG&E to a 100-amp, 2-pole meter/main circuit breaker enclosure mounted on the building
exterior. There is an existing 120/240V, single-phase, three-wire, 4kW backup generator that
supplies emergency power through a 30-amp, 1-pole circuit breaker mounted on the generator.
The generator nameplate lists the rated amperes at 16.7. The 30-amp breaker is too large to
provide overcurrent protection for the generator, and should have been a 2-pole device. It does
not appear that the existing generator was properly sized for the loads that it supplied.
The main circuit breaker and generator breaker supply the normal and emergency sources,
respectively, to a 30-amp, 120V automatic transfer switch (ATS) located in the equipment room.
It is unclear why a 1-pole, 2-wire ATS was selected for this installation. The 100-amp main
circuit breaker does not provide code compliant overcurrent protection for the ATS when power
is supplied by the utility.
The feeder between the main circuit breaker and the ATS is 2-4AWG & 1-6AWGGround. The
feeder between the generator breaker and the ATS is 2-12AWG & 1-12AWGGround. Although
both the utility service and the generator are rated for 120/240V, single-phase, three-wire
operation, they are both connected so that only one phase is used. It is very unusual to connect
this equipment at 120V in lieu of 120/240V.
The ATS load side feeds a 100-amp, 120/240V load center located inside the equipment room
via 2-4AWG & 1-6AWGGround. The load center has six tandem-style 20-amp circuit breakers
installed, which provides capacity for 12 individual circuits. One of the circuits is a spare. A
jumper has been installed between the bus bars in the load center so that it operates at 120V.

The load center supplies a dedicated branch-circuit to the equipment room lights/general
purpose receptacles, six ceiling mounted receptacles for the floor-mounted two-post racks, the
chlorinator system and associated pump, the tank cathodic protection system, and the tank
mixer. There is also a circuit routed above the ceiling in the equipment room, however, the load
served was not visible from the equipment room.
The two-post rack installation facilitates upgrading the communication equipment in response to
improvements in technology. The load for each rack will vary depending on the installed
equipment.
The chlorination system includes a 120V, 1.5 horsepower pump motor. The nameplate on the
motor indicates 18.2 amps at 120V. This exceeds the current rating of the 4kW generator. The
operation of this motor likely contributed to the failure of the existing generator, if it operated
when the generator was providing power. The existing branch-circuit feeding the chlorination
system is protected by a 20-amp circuit breaker. This breaker would not typically account for
the starting current of a 1.5HP motor that is started by an across-the-line contactor. If the
system has experienced nuisance tripping of this circuit breaker, replacing the breaker with a
larger device should address the issue.
The fuel source for the existing generator is a 250-gallon liquid propane gas tank located
adjacent to the generator.
The following items identify where the existing installation should be upgraded to comply with
Electrical Code requirements.
1. The 4-AWG phase conductor from the main circuit breaker to the ATS is rated to carry
85A and is not protected by the 100A circuit breaker.
2. The two-post racks on the west side of the equipment room impinge on the code
required working clearance for the ATS.
3. The 12AWG conductors serving the chlorination system are rated to carry 20 amps. The
minimum circuit ampacity required for the 1.5HP motor is 25 amps. These conductors
will require replacement.
4. Many of the existing conduits do not have code required supports installed.
5. The panel directory in the load center does not identify the loads served by each circuit.
RECOMMENDATIONS
We recommend replacing the failed generator with a new 10kW, 120/240V unit along with a
new 100-amp, 120/240V, 2-pole automatic transfer switch. The generator will need a unit
mounted 2-pole circuit breaker rated 50 amps. The feeder from the generator should be 3-
8AWG & 1-8AWGGround. A new 3-2AWG & 1-8AWGGround feeder is recommended from the
main circuit breaker to the ATS for the normal source. We have attached data sheets for a
generator and ATS manufactured by Kohler that are representative of the materials that we
suggest be used.

The existing liquid propane gas tank is adequate to provide more than 24 hours of full load
generator operation at minimum ambient temperature and with the tank filled to 80% of its
volume.
It would be desirable to provide a new 16-circuit load center as part of the new ATS installation.
This arrangement would provide some added circuit space for future equipment. The existing
load center can be reused if preferred, however, the jumper between the bus bars will need to
be removed so that the new three wire feeder from the new ATS can be connected. A new
feeder would be required from the load side of the new ATS to the existing load center.
The installing contractor should ensure that a main bonding jumper between the equipment
ground connection and the grounded conductor at the generator has not been installed so that
the generator is not connected as a separately derived source.
We suggest locating the new ATS/load center on the south wall of the equipment room between
the rows of two-post racks. Branch-circuits from the new load center can be arranged to
intercept the existing circuits at locations within the equipment room to facilitate transition to the
new load center.
A control method to prevent the chlorination system from operating when power is supplied by
the generator will need to be added.
Our opinion of probable construction cost to install the new generator, ATS/load center, and
intercept the existing branch-circuits is $5,750. This includes a $500 allowance for
modifications to the existing concrete generator pad to accommodate the new generator. The
opinion of probable construction cost does not include the purchase of the generator and
ATS/load center. Also, the cost of any upgrades to the existing installation where code
deficiencies have been identified is not included.
Please let us know if you have any questions or if the City will need assistance with design of
the generator replacement.
Sincerely,
Jill E. Johnson, E15149
