ConocoPhillips Has Emissions at Sweeny Refinery in Texas
ConocoPhillips (COP) said 142 pounds of benzene and 268 pounds of unspecified volatile organic compounds escaped from a wastewater treatment tank at its Sweeny refinery in Old Ocean, Texas, because a pollution control device failed.
Emissions began at 5:54 p.m. local time yesterday and repairs may be complete today, Houston-based ConocoPhillips, the third-largest publicly traded U.S. oil company said today in a filing with the Texas Commission on Environmental Quality.
A failed valve, as well as failure of a motor that operates the valve, caused the emission, according to the filing. The valve was removed for repairs and a replacement motor ordered, the company said.
