SUMMARY: On July 18, 2007, the fan motor
for the intake water cooling tower at the District’s Sleepy Hollow Steelhead
Rearing Facility (SHSRF or facility) malfunctioned. The motor was the original
motor and was seven years old. Without
the cooling tower in operation, the temperature of the intake water in the
facility reached as high as 71.5 °F in the afternoons. Water temperatures over 58 °F are considered sub-optimal for
steelhead rearing and temperatures above 64 °F frequently result in outbreaks of disease and
parasitic infestations. To correct the
problem as expeditiously as possible, District staff retained the facility’s
designer, David Dettman, to confirm staff’s diagnosis and assist with the
installation of a new fan motor. In
addition, staff contacted a local vendor and ordered a new 30-horsepower motor
for immediate delivery. Lastly, because
of the weight of the motor and height the motor needed to be raised during
installation, an articulating crane truck was rented, with an operating
crew. The motor was installed, tested,
and back in operation on July 27, 2007.
During this period, water temperatures in the river were moderated by
low air temperatures and cloud cover such that significant steelhead
mortalities did not occur at the facility due to excessively high water
temperatures.
COST:
The total cost to diagnose the fan motor problem, procure a replacement
motor, and install and test the motor was approximately $5,147. Of this total, $1,591 was paid to David
Dettman, $1,350 was paid to the crane truck operators, and $2,206 was paid for
the replacement motor. This expenditure,
although not foreseen in the Fiscal Year (FY) 2008 budget, is within the amount
budgeted for “general operations and maintenance” at the facility, i.e.,
$41,400. See line item 2-3-1 (A) on
page 17 of the FY 2008 budget.
EMERGENCY AUTHORIZATION AND
REPORTING: District Resolution 2002-08 delegates to the
General Manager authority to expend up to $20,000 in emergency situations
without prior Board approval. Failure of
the fan motor for the intake water cooling tower at the District’s SHSRF is
considered an emergency situation because of the increased risk of mortality to
public trust resources, i.e., steelhead juveniles. Whenever the General Manager exercises this
delegated authority to approve emergency expenditures, he must report these expenditures
to the board at its next regular meeting.
This report meets this requirement.
