HOUSTON (Reuters) - BP Plc shut a gasoline-producing fluidic catalytic cracking unit on Sunday at its 460,000 barrel per day (bpd) refinery in Texas City, Texas, for maintenance repairs, according to a notice filed with Texas environmental regulators.

It was unclear from the notice filed with the Texas Commission on Environmental Quality if the shutdown of FCCU No. 2 was related to an explosion at the refinery on Thursday that forced the plant to cut production.

A BP spokesman was not immediately available to discuss refinery operations.
