Right now, each state in the U.S. has its own laws regarding diesel engine idling, and legislation can vary greatly from state-to-state. Pennsylvania is considering creating new standards and Senate Bill 295 is currently being discussed by the House. The Department of Environmental Protection has taken a long look at the Bill and is recommending that it be made tougher.

Thomas Fidler, Deputy Secretary for Waste, Air and Radiation Management says, "The Department of Environmental Protection fully supports the concept of statewide idling restrictions to limit emissions from diesel-powered commercial vehicles. However, the department cannot support SB 295 in its current form and recommends substantive amendments to bring this legislation in line with neighboring states and better protect the public's health."

There's an entire press release worth of changes requested by the DEP, and it's pasted after the break for your reading enjoyment.
