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.

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."

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

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

4.03 CONTRACT TERM AND PRICE ADJUSTMENTS
A. Contract Term. The Contract term is ten years, subject to earlier termination under Paragraph
4.03.E or another termination provision of the Contract. Contract Year 1 begins on the date the
City accepts the commissioned LOSVS and authorizes routine service, unless another date is
stated in the Contract. Each succeeding Contract Year is the 12-month period immediately
following the preceding Contract Year. The Contract does not renew automatically. Equipment
modification, replacement, relocation, or addition does not restart or extend the Contract term
unless authorized by a written amendment executed by the City.
B. Equipment Lease. The Proposer shall state the monthly LOSVS lease rate for each of Contract
Years 1 through 10. Each rate shall be firm for the applicable Contract Year and shall include
inspections, preventive maintenance, regulatory testing, telemetry, repairs, replacement of leased
equipment, and all other costs required to maintain the LOSVS in compliance with the Contract.
The proposed lease rates shall not be adjusted except by a written Contract amendment
executed by the City.
C. Liquid Oxygen, Delivery, Labor, and Service Rates. The Proposer shall state the Contract Year 1
unit prices for liquid oxygen, scheduled delivery, and supplemental labor and services in the
Pricing Proposal Form. Beginning with Contract Year 2, the FIRM may implement one adjustment
to each applicable price or rate per Contract Year. An increase shall not exceed 5.0 percent of
the then-current price or rate.
D. Price-Adjustment Notice and Effective Date. The FIRM shall provide written notice of a proposed
price adjustment at least 120 calendar days before the beginning of the next Contract Year. The
notice shall identify the then-current price or rate, the proposed price or rate, and the percentage
adjustment.
1. No price adjustment shall be retroactive or take effect during a Contract Year.
7 LOSVS

2. A timely submitted adjustment that complies with this Article and does not exceed 5.0 percent
of the then-current price or rate shall become effective on the first day of the next Contract
Year unless the City exercises its termination right under Paragraph 4.03.E.
3. The City may reject an adjustment as noncompliant only if it is untimely, mathematically
incorrect, exceeds the 5.0-percent limit, or otherwise fails to comply with this Article.
4. If the FIRM does not submit a timely and compliant notice, the then-current price or rate shall
remain in effect for the next Contract Year.
E. City Election Following Price-Adjustment Notice. Within 60 calendar days after receiving a timely
and compliant price-adjustment notice, the City may provide written notice that it elects to
terminate the Contract rather than pay the adjusted price or rate. Unless otherwise agreed in
writing to facilitate an orderly transition, termination shall become effective on the last day of the
then-current Contract Year.
1. The FIRM shall continue providing all required products and services through the effective
date of termination and shall cooperate with the City in coordinating the transition to a
replacement supplier and the removal of the supplier-owned LOSVS in accordance with
Article 1.08.
2. Termination under this Paragraph shall not constitute a default by the City. The City shall not
be responsible for an early-termination charge, lost profits, unamortized equipment or
installation costs, or a similar charge unless that charge is expressly stated in the Pricing
Proposal Form and accepted in the executed Contract.
3. The City shall remain responsible for payment for products delivered and services accepted
through the effective date of termination and for removal costs reimbursable under Article
1.08.
4. If the City does not provide a termination notice within the required period, the compliant price
adjustment shall become effective on the first day of the next Contract Year.
F. Other Charges and Surcharges. Except for charges expressly requested as separate items in the
Pricing Proposal Form and accepted in the executed Contract, proposed prices shall include all
fuel, energy, environmental, hazardous-material, administrative, regulatory-compliance,
minimum-use, equipment-rental, telemetry, maintenance, inspection, delivery, and similar costs.
The FIRM shall not add, revise, or invoice any surcharge or other charge that is not expressly
included in the executed Contract. Any accepted separate charge shall be subject to the
applicable adjustment limit in this Article and shall not be used to avoid that limit.
G. Ten-Year Price Evaluation. For evaluation only, the City will calculate Contract Years 2 through
10 liquid oxygen and scheduled delivery costs by applying the maximum permitted annual
increase of 5.0 percent. The ten-year evaluation factor applied to the applicable Contract Year 1
annual cost is 12.57789254. This evaluation assumption does not guarantee or authorize any
price increase. Actual payments and price adjustments will be governed by this Article and the
Pricing Proposal Form.
