Metro Retrofits Many of its Clean-Fueled Buses to Run Even Cleaner

Tuesday July 09, 2019

The Los Angeles County Metropolitan Transportation Authority (Metro) recently completed an engine retrofit project to reduce emissions on a significant number of its fleet of more than 2,200 compressed natural gas (CNG) fueled buses.

Metro repowered 125 of its transit buses with new Cummins ISLG and L9N Near Zero Emission Natural Gas Fueled Heavy Duty Engines, which will reduce emissions of nitrogen oxides (NOx) by 90 percent and greenhouse gases by nine percent. 

“While people on the street won’t really notice the new engines, residents in our communities will benefit by the reduction in nitrogen oxides and greenhouse gas emissions,” said Metro Board Chair James Butts. “We are appreciative of the funding grant from the MSRC to complete this important conversion.” 

The Mobile Source Air Pollution Reduction Review Committee (MSRC) provided Metro with $1,875,000 in Clean Transportation Funding to complete the installation of the 125 new lower emitting engines in its fleet of 45-foot series composite buses. The MSRC allocates Clean Transportation Funding from a $4 surcharge on vehicle license fees, specifically to be used for local projects designed to reduce air pollution from motor vehicles.

The Cummins ISLG and L9N Near Zero Emission Natural Gas Fueled Heavy Duty Engine was the first CNG mid-range engine to receive emissions certifications from the U.S. Environmental Protection Agency and the California Air Resources Board which meet the 0.02 g/bhp-hr optional near zero NOx emission standard.

“Metro is always looking at innovative solutions and new technologies to improve performance and reduce emissions,” said Metro CEO Phillip A. Washington. “These new low emission engines will help the agency reduce its carbon footprint and provide clean, reliable service for our customers. 

Over its nearly 30-year history, the MSRC has distributed more than $440 million in funding to innovative clean air projects - like these near zero emission engine retrofits - throughout LA, Orange, Riverside and San Bernardino Counties that have helped remove as much as 13,000 tons of air pollution from the skies of Southern California.
