Big Spring Refinery Reports FCCU Emissions Event Miguel E. Andujar DTN Refined Fuels Market Reporter DAVENPORT, FL (DTN) -- Delek US Holdings reported an emissions event at its 75,000 bpd Big Spring Refinery in Big Spring, Texas, according to a filing with the Texas Commission on Environmental Quality. The event began Monday (4/27) at 10:30 p.m. and ended Tuesday (4/28) at 5:30 a.m. CT, lasting about seven hours. The emissions were tied to an equipment malfunction at the fluid catalytic cracking unit (FCCU) regenerator, which resulted in carbon monoxide emissions exceeding reportable limits. CO emissions were estimated at 5,001 pounds. Operators adjusted unit operations to minimize emissions, according to the filing. The refinery primarily produces gasoline, diesel, and jet fuel. DTN reached out to Delek US for additional details but did not get an immediate response. (c) Copyright 2026 DTN, LLC. All rights reserved.
