46 • August 2018 www.concreteproducts.com CalPortland ® Co. is altering the profile of ready mixed delivery on its southern California home turf. Throughout the second half of 2017, flagship concrete business Catalina Pacific ® logged the largest com- pressed natural gas-fueled mixer truck order to date: 118 Kenworth T880S-mounted, 10.5-yd. McNeilus Bridgemaster Transit models, run- ning Cummins Westport Near-Zero ISL G natural gas engines. The delivery accounted for a good portion of Kenworth's initial T880S production and positioned Catalina Pacific with the second larg- est CNG mixer truck fleet in North America—behind Illinois' Ozinga Ready Mix Concrete Inc. (180 mixers). It was timed with U.S. Envi- ronmental Protection Agency and State of California incentives for diesel power unit replacement and new commercial vehicles running engines with emissions profiles below even the EPA 2010 thresholds. Representatives from the Office of Governor Jerry Brown were among participants in an official CNG mixer fleet launch Catalina Pacific staged late last year at the Los Angeles Memorial Coliseum. CalPortland CEO Allen Hamblen framed the business against the Olym- pic Games' history and future: "Catalina Pacific provided the original concrete in the 1920s for the construction of this iconic stadium with our innovative mixer trucks. We provided the concrete for the construction of many new venues when the Olympics returned to Los Angeles in 1984. We are poised to serve the City of Los Angeles with this new 'clean fuel' technology as the Olympics return in 2028." "Catalina Pacific's transition to a fleet of compressed natural gas-fueled mixers contributes to the attainment of greenhouse gas and NOx reduction goals set forth by the California Legislature, Cali- fornia Air Resources Board and other regional and local agencies. By selecting engines fueled by natural gas over diesel, Catalina Pacific continues to demonstrate ongoing commitment to the environment, community, and safety of our employees." EXHAUSTIVE MATH A top ready mixed player in Los Angeles and Orange counties, Catalina Pacific is firmly on a "Road to Zero (Emissions)" by implementing the latest in clean engine technology. Compared to an EPA 2010-compli- ant diesel engine of the same rating, the markedly quieter Cummins Westport 9L package reduces Agency-designated greenhouse gas emis- sions by 15 percent and NOx emissions by 90 percent. The 8.9-liter engine is also compatible with renewable natural gas (RNG), further curtailing greenhouse gas emissions. The Kenworth T880S entered full production as Catalina Pacific weighed CNG power. Coupled with the ISL G Near Zero engine, the T880S offers the producer optimal payload capacity and truck maneu- verability, due especially to the set-forward axle. McNeilus Cos. partnered with Kenworth on a mixer and chassis design accounting for the ISL G, CNG fuel system and requirements specific to a major California concrete fleet. The result is a T880S-mounted 10.5-yd. Bridgemaster and McNeilus NGEN twin vertical compressed natural gas system, affording operators an enhanced, high capacity, low profile back-of-cab configuration. The new Catalina Pacific mixer trucks run on Redeem RNG from Clean Energy Fuels Corp. in Newport Beach, Calif. Redeem is derived from biogenic methane emanating from decomposition of organic waste at landfills, wastewater treatment plants and agricultural waste sources, primarily dairy farms. Clean Energy sources Redeem from 30 facilities across the country, and in 2017 delivered RNG equivalent to 80 million gallons of diesel fuel.

The design uses the Kenworth T880S model's back of cab space without sacrificing rear visibility. PHOTOS: Concrete Products
