Sodium Hydroxide use will not resume projected usage until the colder months in fiscal year 15-16 as currently planned.

Agenda Item Brief: Background:
This is a contract for the purchase of sodium hydroxide for use as the Truckee Meadows Water Reclamation Facility, beginning on June 15, 2015 and expiring on June 30, 2016, with an option to extend for four (4) additional twelve (12) month periods.
Sodium Hydroxide, also known as caustic soda, is used to increase alkalinity in processes operating within the Truckee Meadows Water Reclamation Facility (TMWRF). The increase of alkalinity in a biological process can provide the ideal environment for the biological community we have intended to cultivate. Caustic soda is mainly for the oxidation of ammonia. Ammonia can be more easily oxidized at a higher pH. Sodium Hydroxide is also used to maintain the ideal alkalinity for the Nitrifying bacteria in the Nitrification Towers at TMWRF. This is one of the components of our overall strategy implemented over the last few years to optimize and stabilize TMWRF Nitrogen performance.
If approved, the City of Sparks will enter into a contract with Sierra Chemical Company of Nevada, Inc. Companies that provide Sodium Hydroxide calculate their pricing on a per gallons basis. Following chemical market review TMWRF staff elected to structure the renewal contract for an initial one year period, securing set pricing, with the option of renewing up to four (4) one (1) year extensions, totaling five years.
Solicitation for the Sodium Hydroxide contract, under Bid #14/15-019, was advertised on April 22nd, 2015 in the Reno Gazette Journal and known interested vendors were alerted to the availability to the bid package via the City of Sparks internet website. Four (4) bids were publicly opened on May 7th, 2015 at 2:00 PM at Sparks City Hall. A summary of those bids are outlined in Table 1, attached. The estimated annual cost of this chemical and the shared costs between the Cities of Sparks and Reno are shown in Attachment 1, Table 2, attached.
1. Council could direct the Manager to provide other alternatives.
I move to award Bid # 14/15-019, for Sodium Hydroxide, to Sierra Chemical Company of Nevada, Inc.
