Ultra-low ASH natural gas engine oil

The Eastern Municipal Water District (EMWD) in Riverside County, California, is seeking proposals for a five-year contract to procure ultra-low ash natural gas engine oil (NGEO) through RFP #3835. The procurement targets approximately 10,000 gallons of specialized engine oil annually, specifically designed for fifty-four stationary industrial high-speed 4-cycle Caterpillar and Waukesha engines. The proposed oil must meet stringent chemical specifications, including a sulfated ash content of 0.05% - 0.1% by weight, precise phosphorus content of 370 ppm ± 10 ppm, and zinc content of 400 ppm ± 10 ppm. Additionally, the successful vendor must provide and install a 2,000-gallon, double-wall, UL-rated steel tank at the EMWD Operations and Maintenance Center. The RFP was released on 7/2/2025, with questions due by 7/21/2025 and electronic proposals due by 4:00 PM on 7/31/2025, with anticipated board approval on 10/15/2025 and a contract start date of 12/10/2025. Evaluation criteria will likely include pricing, compliance with South Coast Air Quality Management District Rule 1110.2, and compatibility with Non-Selective Catalytic Reduction (NSCR) systems.

The solicitation does not explicitly outline specific set-aside designations or restrictions for disadvantaged enterprises. The current incumbent vendor is Flyer's Energy, and proposers are required to provide a loaner tank along with the product to be considered for award. Pricing will remain firm for the first year, with potential annual price adjustments of up to 3% thereafter, subject to EMWD's approval and based on factors such as supply price increases, governmental regulations, or consumer price index changes. Payment terms are standard Net 30, with flexibility for proposers to suggest alternate terms on the Price Form. While a specific budget range is not disclosed, the estimated annual usage of 10,000 gallons suggests a substantial contract value over the five-year term. The district will consider alternative tank configurations and is open to remote inventory monitoring solutions if proposed during the submittal process. Proposers must demonstrate comprehensive compliance with California Air Resources Board (CARB) regulations and provide detailed documentation including business information, references, and safety documentation.
