March 8, 2021. The Pasadena City Council’s Municipal Services Committee will likely formally endorse a recommendation by the Department of Public Works to start using renewable natural gas (RNG) in the city’s fleet fueling program in an effort to eventually transition from using fossil compressed natural gas (CNG).

Transitioning to RNG will enable the city to comply with Assembly Bill 32, the Global Warming Solutions Act of 2006, and to qualify to participate in the state’s Low Carbon Fuel Standard (LCFS) Program.

In particular, the Public Works Department is recommending that the city manager be authorized to enter into a contract with Clean Energy Fuels Corp. for the supply of environmentally friendly RNG for Pasadena’s fleet of about 53 vehicles that currently use fossil CNG. These include Pasadena Transit buses, sanitation trucks, dump trucks, sweepers, aerial trucks, and sewer trucks.

Clean Energy will also manage the city’s Natural Gas Fuel Revenue Credit over a period of three years, with the option of two additional one-year extensions, at the discretion of the city manager.

By using RNG, Pasadena can potentially earn environmental commodity revenue. Under the federal Renewable Fuel Standard (RFS) Program, RNG is eligible to receive Renewable Identification Numbers (RINs), which is a mechanism to value the production of federally qualifying biofuels.

The Public Works Department explained that the city will benefit from Clean Energy receiving credits from the RFS Program because it could eventually lead to Pasadena receiving RNG fuel at no cost and without any financial obligations to the vendor.
