LSI Update: New Advisories

The latest advisory included new exclusions for equipment with certain types of propane-fueled engines.

  • Clarification for the use of electric equipment: According to Williams, there has been confusion regarding the stipulation that an operator must demonstrate that electric-powered equipment of less than 19 kilowatts performs the work equivalent of LSI engine-powered equipment. “Typically, electric equipment and electric forklifts have separate motors — they have drive motors and they have lift motors for the mast. Because they are splitting the work, neither of those motors are greater than 19 kilowatts,” he says. “For the most part, any class 1 or 2 electric equipment is eligible to be included in the fleet average calculation.”

  • Continued exclusion of gasoline-fueled GSE from the LSI fleet average calculation: In December 2008, CARB released LSI Program Advisory 08-02. It allowed GSE operators to exclude gasoline-fueled pieces of GSE from FAEL calculations performed for the purposes of determining compliance with the Jan. 1, 2009, FAEL standard because appropriate retrofit kits had not been verified by Jan. 1, 2007. The upcoming advisory allows GSE operators to continue to exclude their gasoline-fueled pieces of GSE from FAEL calculations until Jan. 1, 2013, because appropriate retrofit kits had not been verified by Jan. 1, 2009.

Extended Verification for Propane Retrofit Kits
Nett Technologies Inc. has two retrofit kits available for less-than and greater-than 3-liter engines that were originally verified for model year 1990 engines and newer. CARB has granted the kits extended verification for 1980 and newer LSI overhead valve engines.

“There are certain technical aspects that need to be met, but it basically allows retrofit kits up to 10 years older than what we were allowing before,” Williams says.
