    FAR Part 13 JA Sole Source Emerson - LMA Unloader Valve Kits_Redacted.pdf
    The U.S. Army Corps of Engineers, Walla Walla District, is seeking approval for a sole-source, Firm-Fixed-Price supply contract with Emerson Process Management Power & Water Solutions, Inc. for Governor Oil Pump Unloader Valve Assemblies. This procurement, justified under FAR Part 13.106-1(b) for simplified acquisitions, aims to replace outdated mechanical unloader valve assemblies on Main Units 1-3 Powerhouse Generators at Lower Monumental Lock & Dam. Emerson is the sole provider due to its acquisition of proprietary designs from American Governor Company (AGC) and Pelton, making it the only company capable of supplying compatible retrofit kits that integrate with the existing AGC digital control system and Pelton pumps. The existing components are 55 years old and nearing the end of their service life. Alternatives are not feasible, as redesigning the system to accommodate other vendors would cost over $2 million and take more than four years. The contract includes various unloader assembly kits and spare parts, with delivery expected within 20 weeks. This sole-source approach is deemed necessary to ensure system compatibility, prevent significant costs, and avoid operational risks.
    Technical Specifications.pdf
    This specification outlines the requirements for procuring Governor Oil Pump Unloader valve assemblies for the Lower Monumental Lock & Dam. The project requires replacing existing spring-operated pilot valves with off-the-shelf solenoid-operated hydraulic valves, controlled by time-delay relays and mechanical pressure switches. The system must be compatible with existing Pelton C310 and C90 Governor Oil Pumps, operate on 120VAC, and include detailed documentation for installation, operation, and maintenance. The procurement includes three dual C310 main pump kits and three single C90 jockey pump kits, each with specific components like replacement pilot valve flange assemblies, electro-mechanical pump controls, and oil filter assemblies. A spare parts kit, compatible with both C310 and C90 unloaders, is also required. All components must be new, meet industry standards, and come with a manufacturer's warranty and technical support. Delivery is required within 20 weeks of contract award to the Lower Monumental Project.
