The court of appeals denied a petition for review of orders of the Federal Energy Regulatory Commission. The court held that the commission adequately considered the environmental impact of the end use of natural gas when it approved a pipeline to bring the gas into the Southern California Basin.

North Baja Pipeline, LLC applied to the Federal Energy Regulatory Commission (FERC) for a certificate of public convenience and necessity authorizing the expansion and modification of North Baja’s existing pipeline system to allow for the transport of foreign-sourced natural gas from Mexico northbound into the Basin Region of Southern California. This region – the Basin – was comprised of Orange County and the non-desert portions of Los Angeles, Riverside, and San Bernardino Counties. This same region also comprised the jurisdictional area of the South Coast Air Quality Management District.
