The Philadelphia Diesel Difference Working Group has been formed to help build a coalition of diverse partners with a mutual interest in reducing air pollution from diesel engines in the greater Philadelphia area through voluntary programs and the use of innovative strategies including market-based approaches.

NEXT MEETING
The next Diesel Difference Working Group Meeting will be 10:00 AM on November 17, 2008 at DVRPC's offices at 6th and Race Streets (American College of Physicians). Jump HERE for more information.

EPA Proposal for More Stringent Emissions Standards for Locomotives and Marine Compression-Ignition Engines

March 2, 2007

The U.S. Environmental Protection Agency (EPA) is proposing more stringent exhaust emission standards for locomotives and marine diesel engines. The proposal would significantly reduce harmful emissions of diesel particulate matter (PM) and nitrogen oxide (NOx) emissions from these engines through a three-part program: (1) tightening emission standards for existing locomotives when they are remanufactured, (2) setting near-term engine-out emission standards, referred to as Tier 3 standards, for newly-built locomotives and marine diesel engines; and (3) setting longer-term standards, referred to as Tier 4 standards, for newly-built locomotives and marine diesel engines that reflect the application of high-efficiency aftertreatment technology. EPA is also proposing provisions to eliminate emissions from unnecessary locomotive idling and is asking for comment on a concept to reduce emissions from existing marine diesel engines when they are remanufactured.

Carlisle's Air Quality? Poor, Council Says

February 24, 2007

The air in and around Carlisle is not just bad; it is worse than the air in 96 percent of communities around the U.S.

That's according to the Carlisle Area Health and Wellness Foundation and the Philadelphia-based Clean Air Council, which released a report on the air quality in the Carlisle area yesterday.

While the findings are bad, they said, the good news is that steps can be taken to make the air more breathable.
