Nimbus Fish Hatchery Terminal Structure Slide Gate System Repair

Nimbus Fish Hatchery, Gold River, California

Statement of Work

1. Background

a. General Description:

i. The Terminal Structure (TS) supplies water to the Nimbus Fish Hatchery (NBF) and the American River Fish Hatchery. The NBF uses this water as the primary water supply for their Hatchery 1 & 2 buildings.

ii. The TS is a steel reinforced water tower that regulates pressure through automated water elevation control through a 48-inch slide gate. The slide gate function is necessary for fish rearing operations at the NBF. Without proper function of this slide gate there is increased risk of mortality for Chinook Salmon and Steelhead Trout during their respective spawning and rearing schedules.

iii. The 48-inch slide gate valve regulates and isolates supply water into the TS. Currently, a separate programmable logic controller (PLC) controls the slide gate motor operator, using water level readings from a transducer installed in the TS. The controls keep the water level in the TS at the normal operating level.

iv. The 48-inch slide gate was recently replaced but the existing motor operator was reused.

b. Deficiency:

i. The TS 48-inch Slide Gate is currently out of service. The motor operator is malfunctioning and has left the Hatchery without the ability to operate the gate in “Local”, “Remote”, or with the manual handwheel. The Hatchery has been using a backup water supply valve configuration as their primary means of water supply, but that is not a long-term solution.

ii. The brass nut within the motor operator has failed twice before: once in service after new installation of an automated system, and after the drive stem and drive nut were replaced.

They failed due to excessive friction during opening and closing while in service, which is localized to the gate leaf sliding on the gate frame. The motor operator also gave error codes indicating IE MWG Error and a Torque Limit Exceeded. Troubleshooting by a valve company indicated than an encoder requires replacing.

iii. The automated PLC system is overly complicated for the application, operation, and maintenance.

2. Scope of Work

a. Repair and replacement services are needed on the 48-inch slide gate motor operator at the NBF as soon as possible.

i. Mobilization

The contractor shall submit a Site Use Plan prior to mobilizing on site. This shall include but is not limited to a plan view drawing/image of the work area, identification of construction areas, vehicle storage areas, water drainage locations if sump pumps are used, public access barrier/exclusion plan, construction vehicle routing plan, declaration and specifications of heavy equipment to be used for this job, and contractor parking if not in the public parking lot. This Site Use Plan shall be approved by Reclamation prior to the start of work.

The contractor shall assemble a Site Safety Plan. This document address all site safety issues, like Confined Space Access, Public Safety, site assessment of hazards and mitigations, etc.

Note that there are overhead powerlines near the construction zone. As applicable, indicate the use of cranes and other heavy machinery necessary to perform the work. The contractor shall use caution and best practices to address this hazard during construction. Additionally, the Contractor shall prepare a Job Hazard Analysis (JHA) for all activities.

This is a public use area with parking, bike/running paths, and recreation. The work area will be visible to the public. The contractor shall be responsible for ensuring public safety for the full duration of construction. This includes but is not limited to public access barriers to notify and in some cases prevent the public from accessing the site. An impact to public use areas require coordination with Reclamation and CDFW; for example, if the bike path must be closed or redirected then there is an impact to the public and this must be coordinated with all parties. Refer to Section 5 for specific deliverables.

Some heavy equipment and materials can be stored behind the locked chain-link fence that surrounds the TS. Any material stored onsite shall be done at the risk of the Contractor.

ii. Clearance Placement

A system clearance (Lock Out Tag Out) is required to make this space safe for personnel to perform work. It is a Permit Required Confined Space. The contractor shall take all necessary OSHA, RSHS, and FIST 1-1 (Reclamation Lock Out Tag Out Policy) precautions before performing the work. This includes but is not limited to providing a Clearance Request, Job Hazard Analysis (Safety Plan), the Start Date of the clearance, the End Date of the Clearance, all reference documentation used to determine safe acc

A previous clearance to access the space inside of the TS shows the following clearance points. The contractor shall be responsible for ensuring that all clearance points are relevant to isolating hazardous energy and ensuring the safety of personnel performing the work.
