Today's settlement will lead to the installation of innovative pollution controls on the largest sources of emissions at the Whiting refinery, including extensive new controls on the refinery's flaring devices. Flaring devices are used to burn-off waste gases. The more waste gases sent to a flare, and the less efficient the flare is when burning those gases, the more pollution that will occur. Under the settlement, BP will install new equipment that will limit the amount of waste gas sent to flaring devices in the first place, as well as implement innovative, cutting-edge controls to ensure proper combustion efficiency for any gases that are burned in a flaring device. The requirements, similar to those included in a recent settlement with Marathon Petroleum Corp., are part of EPA's national effort to reduce emissions from flares at refineries, petrochemical and chemical plants.
