EPA has issued guidance to states on how retrofit projects can be
used in state plans to meet federal air quality standards and
conformity determinations. Diesel retrofit technologies can reduce
pollution from the existing diesel engine fleet by up to 50 percent
for nitrogen oxides and up to 90 percent for both particulate matter
and volatile organic compounds. The Energy Policy Act of 2005 (EPAct)
mandated EPA to develop the guidance. Further, the president's FY07
budget request includes $49.5 million to support EPAct's Diesel
Emissions Reduction provision. The guidance also complements last
year's Transportation Act (SAFETEA-LU). For the first time, the Act
directs states and metropolitan planning organizations to give
priority funding to diesel retrofits and other cost-effective mobile
strategies under the Congestion Mitigation and Air Quality
Improvement Program. Information about "Diesel Retrofits:
