(a) Definition. Abrasive particles sprayed forcefully to clean, remove contaminants, or condition surfaces, often preceding coating.

(b) Minimum biobased content. The Federal preferred procurement product must have a minimum biobased content of at least 94 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 April 4, 2013, procuring agencies, in accordance with this part, will give a procurement preference for qualifying biobased blast media. 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 blast media.

(d) Determining overlap with an EPA-designated recovered content product. Qualifying products within this item may overlap with the EPA-designated recovered content product: Miscellaneous products—blasting grit. 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 blasting grit products and which product should be afforded the preference in purchasing.
