In a filing this week with the Federal Energy Regulatory Commission, Sound Energy Solutions outlined changes to its proposed liquefied natural gas terminal at the Port of Long Beach, saying it would reduce emissions of air pollutants and enhance safety. Under the amended proposal, only 120 ships a year would call on the facility instead of the approximately 140 initially anticipated, according to Thomas Giles, president of SES. The company also has eliminated its plan to store on-site the heavy propane and ethane that will come in with the LNG. Instead, under a partnership agreement, those gases will be piped directly to the neighboring ConocoPhillips oil refinery, where they will be loaded onto train cars. Giles said the pipeline will eliminate a lot of truck traffic at the facility to haul the heavier gases to market. Community groups have opposed building the facility in the port because of its proximity to developed areas, including downtown Long Beach. While the changes may allay some community concerns, the overriding concern of the groups is the potential for a catastrophic accident in which LNG itself is released.
