Enforcing Environmental Laws and Permit Appeals

The Environmental Integrity Project regularly takes legal actions against big polluters and government agencies for failing to abide by environmental laws and regulations.


Sunoco Partners Marketing & Terminals

The Environmental Integrity Project, the Clean Air Council, and Sunoco Partners Marketing & Terminals reached a settlement on an air quality permit appeal before the Pennsylvania Environmental Hearing Board (Docket No. 2018-057-L). The settlement, a major victory for clean air in the Delaware Valley, calls for the retirement of 53 tons of volatile organic compound (VOC) Emission Reduction Credits.


Trump Administration EPA

Twelve conservation and community groups, representing millions of people, sued the U.S. Environmental Protection Agency for its decision not to update national standards restricting water pollution from slaughterhouses.

James Lake Gas Plant

A settlement of a lawsuit challenging unpermitted flaring under the Clean Air Act, filed by the Sierra Club, represented by the Environmental Integrity Project, from the James Lake Gas Plant in West Texas has secured penalties and significant pollution reductions for a plant that state and federal regulators have failed to address.

U.S. Steel

Brunner Island Generating Station

The Environmental Integrity Project, on behalf of the Lower Susquehanna Riverkeeper Association, Waterkeeper Alliance, and PennEnvironment filed a notice of intent to sue Talen Energy on August 28, 2018 for violating the Clean Water Act, which triggered the involvement of the Pennsylvania Department of Environmental Protection (DEP) to reach an historic federal judicial settlement. The settlement also resolved a permit appeal, filed by EIP on behalf of the same clients in September 2018.

The Environmental Integrity Project and the Center for Biological Diversity sued the Trump administration over sweeping changes to how the Environmental Protection Agency handles public-records requests under the Freedom of Information Act.
