Special interest groups have a lot to say about EPA’s plans to cut tailpipe emissions.

EPA has received tens of thousands of comments in the two months since the agency proposed two rules — one for cars, the other for trucks — that are designed to cut greenhouse gas emissions from the transportation sector. Observers say the avalanche of responses is a precursor to months of heated debate over the future of U.S. transportation.

The public comment period for the truck rule closed Friday. The public comment period for the car rule is scheduled to close July 5. EPA expects to finalize both regulations by the end of the year.

The two proposed rules, released on the same day in April, would set strict enough limits on tailpipe pollution that manufacturers would be compelled to more quickly shift their production away from vehicles that run on fossil fuels and toward those that are powered by batteries, fuel cells and other cleaner systems.
