SALT LAKE CITY (AP) — A group of doctors concerned about air pollution is asking Utah regulators to put a hold on a major oil refinery expansion.
The Utah Physicians for a Healthy Environment says it will ask regulators Friday to stop Holly Refining & Marketing Co. from going ahead pending a possible court fight.
Utah has five oil refineries, all located in the populated corridor north of Salt Lake City that doesn't meet federal air quality standards. Holly and Tesoro Corp. are embarking on major refinery expansions.
The physicians' group is challenging permit approvals for Holly and Tesoro to an administrative law judge at the Utah Department of Environmental Quality.
Holly says new controls will cut many emissions even as it boosts capacity by half to 60,000 barrels a day of Utah's crude oil.
