1.03 PERFORMANCE REQUIREMENTS
A. The LOSVS shall continuously supply gaseous oxygen to the Superoxygenation System at the
following minimum conditions:
1. Vaporization Capacity: The LOSVS shall continuously deliver not less than 730 scfh of
gaseous oxygen at the required delivery pressure, 24 hours per day, under the specified
site and ambient conditions. The FIRM shall size and arrange the vaporizer or vaporizers
to maintain this capacity during expected frost accumulation and defrosting and, when
multiple vaporizer banks are provided, during normal switching between banks.
a. Site elevation: 900 feet above sea level.
b. Installation: Outdoors and fully exposed to weather.
c. Minimum outdoor design dry-bulb temperature: -20° F.
d. Maximum outdoor design dry-bulb temperature: 110° F.
e. Exposure to humidity, rain, snow, frost, ice, wind, and solar radiation.
2. Maximum process oxygen feed requirement: 1,450 pounds of oxygen per day
(approximately 730 scfh).
3. Service: Continuous, 24 hours per day.
4. Nominal delivery pressure: 100 psig, or as coordinated with ECO Oxygen Technologies.
5. Discharge temperature: Suitable for downstream piping, valves, instruments, and the
Superoxygenation System.
6. Purity: Commercial liquid oxygen with a minimum oxygen purity of 99.5 percent by
volume, suitable for wastewater superoxygenation and compatible with the ECO Oxygen
Technologies Superoxygenation System.
7. Furnish and install all piping, valves, fittings, connectors, supports, and appurtenances
from the LOSVS through the final connection to the plain end of the City’s 1-inch, 304
stainless-steel oxygen piping at the location shown on Conformed Project Drawing D-
102.
a. Provide a 1-inch, full-port, 304 stainless-steel isolation ball valve at the connection to
the City’s piping. The valve shall be designed for gaseous-oxygen service at the
system design pressure and temperature and shall be factory cleaned, assembled,
tested, capped, and packaged for oxygen service in accordance with ASTM G93 and
CGA G-4.1.
b. Provide oxygen-compatible seats, seals, packing, gaskets, and lubricants. Provide a
lockable handle and permanent identification stating: “OXYGEN — OPEN SLOWLY.”

and the FIRM’s regulation stand. The FIRM shall select the connection type and shall
be responsible for compatibility, cleanliness, installation, testing, and leak-tight
performance of the complete connection assembly.
d. The FIRM shall field verify the City’s pipe termination and furnish all components
necessary to complete the connection. For the final oxygen-piping connection, no
piping, valves, fittings, connectors, or other connection materials will be furnished by

LOSVS
the City or Crossland Heavy Contractors beyond the plain-end 1-inch pipe shown on
Drawing D-102.
B. The FIRM shall provide a vaporization system capable of continuously delivering not less than
730 scfh of gaseous oxygen at the required delivery pressure and at the specified minimum
outdoor design temperature. The capacity shall account for site elevation, ambient-temperature
derating, frost and ice accumulation, defrost cycles, and when applicable vaporizer-bank
switching.
C. The FIRM shall select the number, arrangement, and operating sequence of vaporizers. The
FIRM shall describe how the required oxygen service will be maintained or restored during
defrosting, maintenance, and equipment failure.
D. The Proposal shall identify the number and arrangement of vaporizers and state whether the
LOSVS will continuously provide not less than 730 scfh with one vaporizer unavailable because
of maintenance, malfunction, or replacement. Full redundant vaporization capacity is preferred
but is not required. The City will consider the proposed vaporizer arrangement, service continuity,
restoration plan, and associated evaluated cost in its evaluation.
E. If the proposed LOSVS cannot maintain the required capacity with one vaporizer unavailable, the
FIRM shall provide the personnel, replacement equipment, temporary equipment, or other
resources necessary to restore the required capacity within one business day after notification or
discovery of the loss of capacity. If the FIRM fails to restore the required capacity within one
business day, the FIRM shall credit the City the prorated daily LOSVS lease charge for each day
the required capacity remains unavailable, when the loss of capacity is attributable to equipment
or services furnished by the FIRM or to an act or omission of the FIRM or its subcontractors.
