At the end of a report on natural gas vehicle (NGV) developments on Tuesday, “California Port City Runs on Renewable NatGas Muni Vehicles” (Daily GPI, April 19), NGI attributed the repair and maintenance “NGV Easy Bay” system to the wrong company. Easy Bay is a trademarked system developed by Newport Beach, CA-based Clean Energy Fuels Corp., which installs it for facilities operators wishing to modify their operations to accommodate natural gas. NGI regrets the error.
