(a) Definition. Lubricating products formulated to provide lubrication and wear protection for four-cycle gasoline or diesel engines.

(b) Minimum biobased content. The Federal preferred procurement product must have a minimum biobased content of at least 25 percent, which shall be based on the amount of qualifying biobased carbon in the product as a percent of the weight (mass) of the total organic carbon in the finished product.

(c) Preference compliance date. No later than June 11, 2014, procuring agencies, in accordance with this part, will give a procurement preference for qualifying biobased engine crankcase oils. By that date, Federal agencies that have the responsibility for drafting or reviewing specifications for products to be procured shall ensure that the relevant specifications require the use of biobased engine crankcase oils.

(d) Determining overlap with an EPA-designated recovered content product. Qualifying products within this item may overlap with the EPA-designated recovered content product: Re-refined lubricating oils. USDA is requesting that manufacturers of these qualifying biobased products provide information on the USDA Web site of qualifying biobased products about the intended uses of the product, information on whether or not the product contains any recovered material, in addition to biobased ingredients, and performance standards against which the product has been tested. This information will assist Federal agencies in determining whether or not a qualifying biobased product overlaps with EPA-designated re-refined lubricating oil products and which product should be afforded the preference in purchasing.
