General Counsel Approval:  N/A

Committee Recommendation:  The Administrative Committee reviewed this item on May 14, 2018 and recommended approval.

CEQA Compliance:  Project is exempt as defined by the California Environmental Quality Act Guidelines section 15301(i).

 

SUMMARY:  The Sleepy Hollow Steelhead Rearing Facility (Facility) has a large cooling tower onsite for the purpose of reducing the temperature of the raw incoming river water to acceptable levels for the rearing of rescued steelhead. Built in 2002, the tower is in need of normal repair and maintenance to the internal and external plastic panels that air and water pass over to create the evaporative cooling of the water. Over time, these panels have become clogged with deposits and damaged by sun and physical contact. The fan motor is also in need of replacement due to moisture damage and wear. We have a replacement motor onsite and the contractor will do the switch-out with a crane.

 

RECOMMENDATION:  Authorize the General Manager to enter into an agreement with Cooling Tower Technologies (CTT) for cooling tower repair work for a not-to-exceed amount of $51,000 for materials and labor.  

 

DISCUSSION:  The cooling tower was installed at the Facility in 2002. Minor to moderate repairs have been done to the plumbing and fan components over the years, but the large plastic panels and internal media and are now worn and in need of replacement in order for the tower to effectively cool the river water to healthy levels for steelhead rearing. Additionally, the motor is old and corroded and should be replaced with an existing stand-by motor onsite. Staff hopes to have this work completed before the start of the large intake retrofit project at the Facility this summer through fall.

 

Staff contacted five California companies that reportedly do this type of cooling tower work and received replies from three. CTT had the lowest bid and also has familiarity with our Facility as they have done previous repair work on the tower.

 

IMPACT TO STAFF/RESOURCES:  Funds for this project are included in the FY 2017-18 budget under “Aquatic Resources Fisheries” line item 2-3-1A Sleepy Hollow Facility Operations, General operations and maintenance, Account 24-04-785813, $42,000; and line item 2-3-1I Intake/cold well repair and maintenance, Account 24-04-785813, $10,000.
