He wonders…

EPA Readies New Rule Limiting Appeals on Pollution Permits

Pollution permits granted by the EPA can now be contested by individuals in affected communities who don't have the funds to mount expensive legal challenges.

Photo: Billy Wilson / CC BY-NC / Flickr Individuals and community advocates who are unhappy with pollution permits granted by the U.S. Environmental Protection Agency now have an opportunity to appeal the decisions before an independent tribunal called the Environmental Appeals Board.
