Exhibit #1 <br /> Amendment 1 to <br /> Work Order Number 3 <br /> Valve Actuator Additions to North RO Water Plant - <br /> PROJECT DESCRIPTION <br /> This amendment # 1 modifies Work Order #3 to include modifications to the North RO <br /> water plant permeate degasifier valves and dampers to allow automation of each. <br /> Automation will allow equipment to be taken off-line when not needed for treatment <br /> capacity and will reduce operating costs of the facility . The scope of work consists of <br /> design, modifications to the finish water stabilization (FWS) drawings to include these <br /> design changes, preparation of specifications , and bidding support needed to implement <br /> automation of the post-treatment system at the North RO water treatment plant. In <br /> summary, the additional scope of work in general , consists of. <br /> SCOPE OF SERVICES <br /> 1 . Consultant will review existing process equipment at the North plant and evaluate <br /> options for implementing valve actuators on the permeate piping to each degasifier <br /> and air header dampers from each degasifier. The attached exhibit illustrates the <br /> locations where actuators are required. <br /> 2 . Consultant will design improvements to the permeate degasifier inlet valve to <br /> include new valves and actuators in the degasifier inlets, and actuators and dampers <br /> on the air header system to allow isolation of individual degasifiers . Consultant <br /> will design a pressure relief system to prevent over-pressurizing of the permeate <br /> piping in case of valve failure . Consultant will design I&C improvements needed <br /> for each actuator, including power and instrumentation. <br /> Consultant will prepare revised drawings that illustrate the valve actuator <br /> improvements and include these drawings as an addendum to the finish water <br /> stabilization project currently being prepared for advertisement. Mechanical, <br /> electrical , and instrumentation drawings will be modified to include these changes . <br /> The drawings will be included as an addendum to the FWS project documents . <br /> 3 . Consultant will prepare an operating logic and description for the sequencing of <br /> each of the valve and damper actuators . This description will need to be integrated <br /> within the existing plant operating logic and will be used by the contractors I&C <br /> integrator. <br /> 4 . Consultant will provide construction phase and operation startup services of this <br /> - element which will consist of review of submittals, coordination and oversight of <br /> implementation of the operational sequencing and integration of the existing PLC <br /> and HMI system, and observation of the operating sequence . <br /> K:\WPB_Civil\044572022 -.
