What's at Stake

Our national parks are blanketed by haze pollution, just one impact of old and dirty coal plants. Earthjustice is suing the EPA to close a loophole that will further worsen visibility in these treasured places.

Case Overview

Air pollution generated by the nation’s old dirty coal plants doesn’t stay where it’s emitted. It drifts on air currents to many unwanted places, including our national parks. Because of this haze, visibility in western parks is often half what it used to be—in eastern parks it’s many times worse.

It’s EPA’s job to reduce this haze in order to protect our country’s special places and the health of visitors who travel to see them. Instead, the agency recently created a giant loophole for old coal plants by exempting them from installing technology to reduce pollution if they’re located in any of the 28 states subject to EPA’s Cross-State Air Pollution Rule (CSAPR).

Earthjustice supports CSAPR and is defending it from industry attack. But, we’re also challenging this dangerous related exemption to ensure that coal plants aren’t given any more free passes to pollute our parks and communities.
