CALIFORNIA AIR RESOURCES BOARD ABANDONS ORIGINAL ESTIMATES OF OFF-ROAD DIESEL EMISSIONS, CONCEDING OFF-ROAD RULE NOT NEEDED TO MEET EMISSIONS GOALS

Board Now Predicts that Off鈥揜oad Diesel Emissions Will be Lower than State鈥檚 Goals for Years to Come, Contractors Urge Immediate Repeal of Unneeded Rule

The California Air Resources Board abandoned its original estimates of off鈥搑oad diesel emissions today, conceding that its 鈥渙ff鈥搑oad rule鈥 is not needed to meet ambitious goals for the off鈥搑oad equipment in the construction and certain other industries. According to new estimates that the agency staff developed over the summer, off road fleets of diesel equipment will exceed the state鈥檚 emission goals for many years to come.

During the earlier rulemaking process, the board staff used the now abandoned estimates to justify an 鈥渙ff鈥搑oad rule鈥 that would needlessly force contractors across the state to retire, retrofit, repower or replace billions of dollars worth of construction equipment, and all at a time when California鈥檚 construction industry is still losing jobs. When informed of the state鈥檚 new forecasts, association officials called on the Board鈥檚 members to repeal the rule 鈥渜uickly and completely.鈥

鈥淭he fact that this agency has been willing to find and fix the significant flaws in its original estimates is a victory for sound science over rash regulation,鈥 said Mike Kennedy, general counsel for the Associated General Contractors of America. 鈥淎s the agency鈥檚 own data now makes clear, it is time for the board to repeal its costly and unneeded rule.鈥

Kennedy said the are for emissions of nitrogen oxide from the regulated fleets to fall well below the levels that the state has targeted in each and every year through 2025. The state now predicts that emissions of particulate matter will fall below the targeted levels through 2015 and will remain close to those targets through 2025.

The state agency revised its diesel emissions estimates after an analysis of the state鈥檚 original 鈥渆missions inventory鈥 found significant flaws in the state鈥檚 data. That , conducted by Sierra Research on behalf of the Associated General Contractors of America, found that the state has systematically over鈥揺stimated diesel emissions from off鈥搑oad equipment by a factor of 3.5. The new data that the state released today essentially confirms that finding, association officials noted.

鈥淭he good news is that thousands of construction workers won鈥檛 have to lose their jobs on account of bad science and erroneous estimates,鈥 said Kennedy. 鈥淭he construction industry is now eager to work with the board to find ways to meet ambitious environmental goals and still protect the state鈥檚 remaining construction jobs.鈥
