MuckRock has won the First Amendment Coalition’s Free Speech and Open Government Award for its data journalism collaborations and was named a finalist for the National Institute for Health Care Management Awards and Sigma Awards.

At the American Geophysical Union conference this week, MuckRock and The California Newsroom presented findings and methodology from the “Smoked Screened” investigation.

Dozens of states and the EPA are so concerned they may exclude the smokiest days from the legally binding score cards that determine whether they’re doing enough to fight pollution, according to a joint collaboration between the Tribune and the nonprofit news site MuckRock. Now some states are considering banding together in a joint effort that could trigger the largest exclusion in the history of the federal Clean Air Act

Everyone agrees it’s time to change the Clean Air act’s exceptional events rule, but has different solutions.

Across the US, local governments, lobbyists and industry have spent millions to get wildfire pollution excluded from the record. People like Robert Shobe pay the price.

MuckRock and The California Newsroom spent a year requesting and analyzing EPA data on air pollution and talking with experts about what the data means. Here’s how we did it and what it means for the more than 21 million Americans impacted by a regulatory loophole in the Clean Air Act.

Major investigation shows local governments are increasingly exploiting a loophole in the Clean Air Act, leaving more than 21 million Americans with air that’s dirtier than they realize

First pushed through by the Republican senator and climate denier Jim Inhofe, the rule has become a “regulatory escape hatch” for states that want to meet federal air-quality standards.

Congressional investigators say the use of a regulatory loophole to erase smoke pollution from the official record is on the rise.
