PERFORMANCE WORK STATEMENT

CHILLER RENTAL FOR LIVINGSTON STONE FISH HATCHERY

January 2022

PART 1 GENERAL

1.01 BACKGROUND

A. The Bureau of Reclamation, Northern California Area Office (NCAO) located in Shasta Lake, CA, requires a water chiller system of appropriate size and capacity to cool influent water of the Livingston Stone National Fish Hatchery (LSNFH) during late summer and fall of 2022.

B. The hatchery is approximately 500 yards downstream of Shasta Dam, and is supplied water from the penstocks for Shasta Powerplant generating units two, three, and four. A recent operational model indicates a low lake level elevation this season may produce penstock water temperatures this year above those considered safe for hatchery operations. Water temperatures exceeding 56 deg. F are detrimental to the winter run eggs under incubation and fish rearing at the hatchery. A supplemental system to adequately cool the supply water must be in place before temperatures reach dangerous levels.

1.02 SCOPE

A. The Contractor shall supply a chiller system capable of supplying cooled inlet water to the fish hatchery for a minimum of five months, according to the specifications below. The Contractor will install the equipment, service the equipment at manufacturer’s recommended intervals, remove the equipment, and return the site to its original condition.

1.03 OBJECTIVE

1.06 ITEMS SUPPLIED BY THE GOVERNMENT

A. Utilities

1. Power at 13.8kV/3PH currently serves the hatchery site and some of that power is available for equipment use. The design of interest includes an air-cooled chiller of 500-ton capacity be run from a rented transformer and load center producing a minimum of 1200 amps at 460V; and a separate system of one 500-ton water-cooled chiller and one 200-Ton air-cooled chiller run by a 1.0MW diesel generator. The government will supply the power to the rented transformer system and diesel for the generator-powered system.

2. The water-cooled chiller must have an evaporating tower that adheres to waste consideration of these specifications. Waste from the chillers must be chemical-free. Pricing for the complete piping assembly must be included in the submitted proposal. Extra cooling and makeup water is available from the hatchery intake pipe at a maximum flow rate of 300 gpm, and no additional equipment cooling water supply sources are available.

3. Potable drinking water is available during scheduled equipment service events.

4. Restroom facilities are available during scheduled equipment service events.

PART 2 TECHNICAL REQUIREMENTS

2.01 DOCUMENTATION

A. Inspection Standards

1. Chiller equipment reliability is paramount to hatchery operations.

2. Contractor must inspect and maintain the rented equipment according to manufacturer’s requirements.

3. The inspection and maintenance schedule, and manufacturer’s maintenance specifications, must be submitted to the COR at least 14 days prior to delivery of the equipment.

2.02 WORK TO BE PERFORMED

A. Contractor shall provide all labor, tools, special tools, lifts, safety equipment and consumable materials including startup fuel, cleaning products, lubricants, and grease as required to complete the installation and maintenance work.

B. A log of maintenance work performed, in the Contractor’s format, shall be delivered to the COR monthly. The form must include the date, items addressed, and signature of staff conducting maintenance.

2.03 MATERIAL LIMITATIONS

A. The water that is used within LSNFH cannot contact the following prohibited metals

- copper, zinc or brass due to the possibility of ion exchange causing harm to eggs, fry and juvenile fish. Acceptable materials include PVC, rubber, stainless steel, titanium, and carbon steel that does not contain any of the prohibited metals listed previously. Bronze or steel pump impellers are allowed as long as they don’t have the prohibited metals exposed to the hatchery water.

B. For water chillers that contain the prohibited metals in associated recirculation pumping systems, such as evaporative cooling towers, no additional chemicals that are toxic to fish of any stage, such as descalants or biocides, may be used or wasted on hatchery property. Any descaling operations must be performed off-site.

2.04 EQUIPMENT POSITION AND OPERATION

A. The chiller system will consist of two chiller package systems supplying a central heat exchanger: one electric powered air-cooled system and one water/air-cooled dual chiller system, powered from separate supply sources to reduce loss of continuous service. Total chilling capacity requirements are described in Section 2.05. The location identified at the hatchery where chillers must be located will be near enough to the main water supply pipeline valve assembly to minimize piping. The valve assembly is equipped with butterfly valves upstream and downstream of an in-line valve that controls total flow to the hatchery. The Contractor must connect chillers to 10-inch flange inlet and outlet pipes, and install all piping, valves, hoses, and fittings as needed.

B. Each chiller package must be provided with its own associated controls to properly run the chiller package. Manual switching between chiller packages is acceptable during maintenance until chillers are returned to service.

C. Operation will be by parallel flow though the chillers into a central heat exchanger, and chilled water to the hatchery will be manipulated by automated temperature monitoring, with visible temperature monitors on all chillers. When only one chiller is required to supply the required flow demand, the other chiller will remain in standby.

When chilled water flow demand exceeds the production limit of one chiller, the other package must be able to augment chilled water flow until the required total chilled water flow rate is achieved. It is permissible to require manual starting of the alternate chiller, but once started, the chiller must maintain automatic control of effluent temperature.

D. Package system must be able to monitor and alarm if either chiller package fails in any way to meet the full demand. Alarms of insufficient pressure, flow, and temperature must be included in each chiller package. Visible lights or other alarm notifications are at the discretion of the manufacturer. All chiller packages supplied shall be required to provide the required chilled water continuously throughout the rental period, except for regular scheduled maintenance service.

E. Waste from the water-cooled chiller evaporative cooling tower must meet the criteria of the LSNFH pollutant waste discharge permit after blending with the hatchery effluent water. These criteria include no more than 5-degree F increase in the combined waste discharge.

F. The Contractor shall supply and install all power load centers, transfer switches, electrical cables, conduits, connections (including high voltage connection from supply to transformer), breakers, disconnects, relays, controls and other items as needed for each chiller package supplied to comply with all applicable Electrical Codes, Environmental & Air Quality regulations, and Safety regulations and performance requirements as described herein. The generator shall have a current Air Quality Permit for Shasta County and have current compliance documentation provided by the rental contractor.

2.05 EQUIPMENT CAPACITY

1. The total chilled water flowrate minimum is 2,800 gpm.

2. Multiple chiller packages must supply a central heat exchanger.

3. Any equipment that fails during the rental period must be replaced or repaired within 36 hours of notification by the COR.

4. Minimum temperature reduction at full flow rate from equipment influent to the hatchery is 10F.

5. Fuel storage must be sufficient for 24-hour operation for the duration of the contract.
