   DAVENPORT, FL (DTN) -- Valero Energy's 200,000 bpd McKee refinery in Sunray, 
Texas, is scheduled to begin five days of maintenance Thursday (9/10) involving 
Complex 1 and Complex 3, according to a filing with the Texas Commission on 
Environmental Quality (TCEQ).

   The maintenance is scheduled to begin at 3:00 p.m. CT Thursday and continue 
through 3:00 p.m. Tuesday (9/15). Valero submitted the initial notification on 
August 31.

   Equipment listed in the filing includes the fluid catalytic cracking unit, 
or FCCU, along with the FCCU flare, hydrocracker flare and No. 1 Main Refinery 
Flare.

   The FCCU is a key gasoline-producing unit that converts heavier refinery 
streams into gasoline blendstocks and other lighter products, while 
hydrocracking operations are important for producing middle distillates, 
including diesel and jet fuel. The filing did not indicate whether production 
would be affected during the maintenance.

   The refinery expects opacity at the FCCU stack could reach 100% during the 
maintenance activity, compared with a permitted limit of 35%, according to the 
filing.

   Operations and maintenance personnel will follow established procedures to 
reduce and minimize emissions during the work.

   The McKee refinery primarily produces gasoline, diesel and jet fuel.

   DTN reached out to Valero Energy for additional details but did not get an 
immediate response.
