This week, the Senate Environment & Public Works Committee passed S.B. 3973, the “Voinovich-Carper Diesel Emissions Reduction Act of 2010”. This is a significant step on the bill’s path to (hopefully) becoming law. The next step is for the bill to come before the full Senate.
Originally passed in 2005, the Diesel Emissions Reduction Act (DERA) is designed to improve air quality (and thus public health) by replacing, upgrading and modernizing older diesel engines and equipment. DERA has been a popular program at both the state and federal levels. It is, however, set to expire in September 2011 if it is not reauthorized.
Compared with gasoline engines, diesel engines are generally more fuel efficient and have a longer life span, but without the proper technology, they produce greater and more deadly air emissions than their gasoline counterparts. Dirty diesel emissions are linked to 21,000 premature deaths, hundreds of thousands of asthma attacks, and numerous other health impacts every year in the United States.

New federal standards for diesel engines began in 2007, making modern diesel engines 90% cleaner than they were a decade ago. However, those standards don’t apply retroactively to the more than 11 million diesel engines manufactured before 2007. In many cases, those older engines will be in operation for 30 years or more and continue to emit harmful pollutants and impact our air quality and the public health. DERA offers a solution by funding retrofits such as pollution control devices, accelerated fleet replacement, engine rebuilds and the like.
Retrofitting diesel engines provides enormous environmental benefits, yet there are few direct economic incentives for vehicle and equipment owners to implement these retrofits. The financial incentives available through DERA support voluntary, rather than regulatory, efforts to protect human health and help states meet EPA-mandated air quality standards.

These projects are helping clean up engines that would otherwise pollute our air for many years to come. Across the country, DERA is clearly making a significant impact in our communities; the National Academy of Sciences calls DERA one of the most cost effective air quality projects in the nation. According to the EPA, for every dollar spent, DERA produces $13 in health and economic benefits.
On Tuesday, even global warming skeptic Sen. Jim Inhofe, R-Okla., praised the program during a meeting of the Standing Committee on Environment and Public Works. The following quote appears in the committee’s press release:
“I am pleased that the EPW Committee was able to come together and pass common-sense environmental legislation,” Inhofe said. “The Diesel Emissions Reduction Act of 2010 and the Reduction of Lead in Drinking Water Act will reduce emissions with real public health impacts and lower the level of lead in drinking water. Notably, they will achieve these worthy goals without sacrificing jobs or economic growth. Here, then, are models of bipartisan environmental legislation that I hope will swiftly pass through Congress and become law by year’s end.”
Nationally, DERA is supported by a broad coalition of more than 500 industry representatives, environmental and public health organizations, and state and local government associations. Two senators from the Southeast, Sen. Hagan, D-N.C., and Sen. Alexander, R-Tenn., are co-sponsors of this important bill. Given the highly politicized climate on Capitol Hill, passage could be difficult despite this broad range of support.
S.B. 3973 is slated to be heard on the Senate floor this week and it will then move on to the House Energy and Commerce Committee. Supporters need to speak up. Please contact your senators and representatives and ask them to protect human health and the environment by supporting S.B. 3973, the “Voinovich-Carper Diesel Emissions Reduction Act of 2010.”
