The 'Fleet Averaging Rule' takes effect in California 1/2009. It does not require anyone to switch to an electric truck. It requires owners of medium (4-25 forklifts) and large (25+ forklifts) fleets to maintain an average emissions (NOX&HC) level, based on the emissions rating of each LSI engine (electric trucks have an emissions rating of 0, for this purpose).

Small fleets (1-3) are exempt. There are other exemptions and restrictions, as well. If you are in CA and you have at least 2 more forklifts, you will need to do something to reduce your fleet average, as the two older IC trucks are uncontrolled and will bring the average way up. There are retrofits for some older engines.

CARB (California Air Resource Board) has a calculator on its site to figure out your fleet average.

I thought I read that all IC trucks will have to have reduced emissions before the catalytic converter, and if the engine is not cabable of the lower emissions, then you must retro-fit or get the unit out of California.

I'll see if I can find that article...

I believe that the 2009 lift truck emissions standards only apllies to truck produced in 2009 possiply for Califrnia it may apply to trucks shipped into the state.

But what you greater concern would be is teh emmission levels inside your building OSHA and CALOSHA have specific standards that must be meet. Just a guess those early 1980 units are probably not the cleanest running forklifts and are emptying you pocket with repairs.

What you might want to consider is switch to electrics, finance them to own for 6 - 7 years. The monthly payments would be very reasonable and your repairs costs would go away (except for abuse) for 1 -2 years (warrranty coverage), your fuel costs would be significantly lower. Your in plant emissions is a non issue. Plus, I believe CA offers tax incentives to companies that switch from propane to electric.

Talke to your local dealer and explore your options.
