ABRASIVE BLASTING PROGRAM - CERTIFIBD ABRASIVES

Toe Health and Safety Code authorires the Air Resources Board (ARB) to adopt air pollution standards for sandblasting operations. Toe current regulations require that all abrasive blasting be conducted within a permanent building with some specific exceptions. Exceptions allowing outdoor blasting exist when 1) steel or iron shot/grit is used exclusively, or 2) the blasting is conducted with ARB certified abrasive, wet, hydroblasting, or vacuum blasting techniques and the item blasted exceeds 8 feet in any dimension or is situated at its permanent location. Toe current regulations apply a 40 percent opacity visible emission standard to all permissible outdoor blasting and a 20 percent opacity standard to all permissible indoor blasting regardless of the abrasive or the blasting technique used.

Under Title 17 of the California Code of Regulations, the ARB is required to certify abrasives used for permissible dry outdoor blasting as complying with specific performance standards. The performance standards require that the abrasives shall not contain more than 1% by weight material passing a #70 U.S. standard sieve before blasting, and that after blasting the abrasives shall not contain more than 1.8% by weight material 5 microns or smaller. As an alternative to the before-blasting requirements, the abrasive shall not produce visible emissions more than 20% opacity when blasted in accordance with a specified test method. Compliance with these certification requirements helps to reduce fine particulate matter emitted to the atmosphere during permissible dry outdoor blasting.

Executive Order G-95-083 lists abrasives currently certified by the ARB in accordance with Section 92530 of Subcbapter 6, Title 17, California Code of Regulations. The certification of the abasives on this Executive Order will expire in either 1996 or 1997 depending on when the abrasive was certified. New Executive Orders will be issued as appropriate.

If you have any questions regarding Executive Order G-95-083 or the certification process, please call Ms. Kathryn Gugeler at (916) 327-1521, or Ms. Laura McKinney at (916) 327-1525.
