DESCRIPTION/SPECS/WORK STATEMENT

Wolf Creek Dam Liquid Oxygen Supply Acquisition

Wolf Creek Dam — Jamestown, KY

1.0 SCOPE OF WORK

The work to be performed under this contract consists of supplying and delivering bulk Liquid Oxygen (LOX), as described in Section 2.0 below, to the U.S. Army Corps of Engineers (USACE) cryogenic facility, located at Wolf Creek Dam in Jamestown, KY.

The operational Dissolved Oxygen (DO) season is estimated to run from September 1, 2026, through November 30, 2026. The overall contract delivery period is from September 1, 2026, through December 31, 2026, to allow for seasonal start-up, ramp-down, final system deactivation, and any post-season inspections.

2.0 LIQUID OXYGEN REQUIREMENTS & DELIVERY PHASES

The Contractor shall furnish bulk liquid oxygen meeting the technical and phased logistical specifications detailed below.

a. Technical & Purity Standards

Bulk liquid oxygen supplied under this contract shall comply with the Compressed Gas Association (CGA) G-4.3 commodity specifications and must be certified at or above 99.5% purity.

b. Seasonal Phasing & Delivery Capacities

The daily LOX requirement is highly variable and depends on real-time environmental factors (such as water temperature and natural DO levels) as well as dynamic hydropower generation schedules. Gaseous oxygen flows are estimated to range between 300 and 3000 SCFM depending on daily demand. The Contractor must possess the production, storage, and fleet capacity to scale deliveries across five distinct seasonal phases.

Note: The tonnage ranges listed below represent required logistical delivery capacities for each phase. Actual ordered quantities will fluctuate within the ranges and the timing of phase initiation may vary. The delivery capacity requires the ability to dispatch multiple trucks per day, as a standard 23-ton tanker alone will not meet requirements.

1. Phase I: Seasonal Start-up Demand (System Initiation)

• Objective: Support the transition of the cryogenic system from an inactive to an active state.

• Logistical Capacity: Delivery capability of a daily average of twenty-three (23) to forty-six (46) tons, seven (7) days per week, for up to two (2) consecutive weeks.

2. Phase II: Initial Shoulder Season (Low to Medium Flows)

• Objective: Support the system as reservoir flows require low-to-moderate oxygenation.

• Logistical Capacity: Delivery capability of a daily average of forty-six (46) to ninety-two (92) tons, seven (7) days per week, for up to two (2) consecutive weeks.

3. Phase III: Peak Season Demand (Surge Capacity)

• Objective: Support maximum system operation during peak heat and generation periods.

• Logistical Capacity: Delivery capability of up to a maximum of one hundred twenty (120) tons per day, seven (7) days per week, for up to four (4) consecutive weeks.

4. Phase IV: Final Shoulder Season (Low to Medium Flows)

• Objective: Support the system as temperature levels fall and peak usage wanes.

• Logistical Capacity: Delivery capability of a daily average of forty-six (46) to ninety-two (92) tons, seven (7) days per week, for up to two (2) consecutive weeks.

5. Phase V: Seasonal Ramp-down Demand (Deactivation)

• Objective: Support the system as it transitions down to minimal flows prior to winter shut-off.

• Logistical Capacity: Delivery capability of a daily average of twenty-three (23) to forty-six (46) tons, seven (7) days per week, for up to two (2) consecutive weeks.

c. Estimated Contract Quantities

The total estimated demand quantity for the entire 2026 season is six thousand (6,000) tons of LOX. This total is an estimate for budgeting and planning purposes; the Government is only obligated to pay for actual tons ordered, delivered, and accepted.

However, the Contractor must maintain the readiness and capability to deliver up to the surge volumes specified in Section 2.0.b.

3.0 CONTRACTOR INSPECTION & COMPLIANCE ACCOUNTABILITY

The Contractor shall be solely responsible and accountable for all safety, equipment, and structural inspections required to safely transport, transfer, and deliver LOX into the Government-owned storage tanks.

a. Routine & Pre-Delivery Inspections

1. The Contractor is responsible for inspecting and verifying that all transport trailers, hoses, couplings, adapters, valves, and safety relief devices are in safe working order, clean for oxygen service, and comply with CGA and Department of Transportation (DOT) guidelines.

2. The Contractor must inspect and confirm that all safety protocols, static grounding, and delivery connection points are verified immediately prior to starting the transfer process.

b. Post-Delivery Valve and Connection Audits

The delivery driver must conduct a final walk-around inspection after completing each delivery. The driver shall verify that all fill-pipe valves are returned to their designated operational positions, the system is free of leaks, pressure levels are stable within parameters, and all fill pipes have returned to ambient temperature and completed venting before departing the cryogenic facility.

4.0 WARM FILL INSPECTION SERVICES (SEPARATE CLIN)

In cryogenic storage, allowing a tank to warm up to ambient temperature introduces critical structural and purity risks. If a storage tank is emptied unexpectedly (e.g., due to an unplanned system leak, equipment failure, or sudden seal compromise), the tank will warm up.

To manage this risk, a separate, dedicated contract line item (CLIN) is established for Warm Fill Inspection and Purging Services.

a. Contractor Technical Scope of Work

If the Government-owned storage tanks are emptied unexpectedly and warm to ambient conditions, the Contractor must perform the following tasks before resuming deliveries of LOX to the affected tank(s):

1. Structural & Integrity Inspection: Visually and physically inspect the tank's exterior casing, vacuum valves, and connection ports to ensure no structural warping, vacuum loss, or structural fatigue occurred during the rapid de-inventory and subsequent warming.

2. Moisture & Contamination Purging: Perform professional purging of the tank interior to extract ambient air, moisture, and potential contaminants that entered the tank while depressurized, utilizing gaseous nitrogen or oxygen in accordance with CGA G-4.1 (Cleaning Equipment for Oxygen Service) and CGA G-4.3 guidelines.

3. Controlled Cool-Down Procedure: Execute a controlled cool-down process to lower the internal temperature of the tank gradually, preventing thermal shock to the inner vessel, piping, and seals.

4. Purity Verification: Sample and analyze the tank atmosphere to certify that the moisture levels and gas purity meet the minimum threshold of 99.5% purity prior to commencing standard bulk refills.

b. Activation of Warm Fill Services

This service shall be activated on an on-call basis via formal notification from the Contracting Officer or Government Representative. No warm fill operations shall occur without prior written authorization. The Contractor shall propose a fixed, per-event rate for this service under the designated CLIN.
