Today, clean air advocates filed a lawsuit in U.S. District Court in Seattle to require five oil refineries in the state to improve energy efficiency and take other steps to reduce their greenhouse gas emissions.
The clean air advocates are urging state and regional permitting agencies to control greenhouse gas emissions from all five oil refineries in the state, as required by the federal Clean Air Act. The five refineries are BP Cherry Point in Blaine, ConocoPhillips in Ferndale, Shell Oil in Anacortes, Tesoro in Anacortes and U.S. Oil in Tacoma.
"Every one of these refineries is currently operating without any controls whatsoever over their greenhouse gas pollution,” said Janette Brimmer, an attorney with Earthjustice. “We’re asking the clean air agencies to enforce laws already on the books.”
Oil refineries are a major source of greenhouse gas emissions nationally, and Washington’s five oil refineries contribute significantly to statewide greenhouse gas emissions. Together Washington refineries account for an estimated 8 percent of the state’s global warming pollution, making the sector one of the largest single contributors of greenhouse gas emissions in Washington.
The oil refineries also emit methane and nitrous oxide, which are more potent greenhouse gases than carbon dioxide, as well as several other air contaminants that pose risks to human health and the environment such as hydrogen sulfide, sulfur dioxide, nitrogen oxides, particulate matter, and volatile organic compounds. Four of the five refineries are operating under expired Clean Air Act permits, making now a critical time to update their pollution control technology.
State and regional permitting agencies are mandated to require reasonably available control technology (RACT) for all air contaminants from the refineries. The agencies failed to apply RACT for greenhouse gas emissions at all of Washington’s refineries. The advocates sent notice of this failure last summer, expressing intent to pursue a lawsuit, if necessary, to protect children, property and business owners and the natural environment from the oil refineries’ pollution.
“In the absence of federal action on climate change, it’s time for us to get moving at home,” said Joan Crooks, Executive Director of Washington Environmental Council. “The pollution from these refineries is a threat to the health and future of Washingtonians. There’s technology available to reduce pollution and they should be using it to protect our state’s health.”
The oil refineries burn fossil fuels in the process of converting crude oil into usable products such as gasoline, jet fuel, and asphalt. As a result of this combustion and the refining process, the oil refineries emit significant greenhouse gases from their process heaters, boilers, fluid catalytic cracking units, hydrogen production units, sulfur recovery plants, and other facilities and units at the refineries.
According to an Environmental Protection Agency report, there are numerous efficiency improvements for reducing greenhouse gas emissions from oil refineries, including boiler and steam system optimization, efficiency improvements in process heaters and motors, and waste gas and power recovery. None of Washington’s oil refineries are currently Energy Star certified, indicating that there are significant opportunities for improvement at each of them.
“These changes will certainly result in refinery operation efficiencies that will actually save money,” Aaron Robins of the Sierra Club. “It’s really a win-win. The refineries, by investing in the latest efficiency improvements now, will cut both greenhouse gas emissions and costs in the future. It’s a win for Washington residents because these initial steps will protect their health and welfare from harmful pollution.”
The suit was filed by Sierra Club and Washington Environmental Council, represented by Earthjustice and Ziontz, Chestnut, Varnell, Berley & Slonim.
