California Board Approves Diesel Soot-Trap Retrofit
The California Air Resources Board gave approval to a plan that would require 1.25 million diesel engine owners to retrofit their engines with soot traps.
Environmentalists applauded the plan, but representatives of the trucking industry submitted an alternative strategy involving grants to help carriers buy cleaner equipment that would be paid for by a $50 fee for all trucks that operate in the state.
CARB approved the new master plan for dealing with diesel engines of all types Sept. 28, but the specific regulations to implement each part of the plan must still be written and endorsed.
