The U.S. Small Business Administration (SBA) is modifying the small business size standard for petroleum refiners for purposes of Federal government procurement. The modification consists of the following: Increasing the capacity component of the standard from 75,000 barrels per day (bpd) to 125,000 barrels per calendar day (bpcd); defining capacity in bpcd; and measuring a refiner's total Operable Atmospheric Crude Oil Distillation Capacity. This is a better definition of what size a refiner must be to qualify as a small refiner for the Federal government's procurement of refined petroleum products. SBA is not changing the 1,500 employee size standard for this industry.
