Earthjustice, on behalf of Citizens for Pennsylvania’s Future, Gasp, Louisiana Bucket Brigade, and Sierra Club, sued the U.S. Environmental Protection Agency for improperly regulating coke ovens — producers of known carcinogens — thus failing to protect communities throughout the country. Over a decade ago, EPA found that carcinogenic emissions from coke ovens destroy air quality and cause devastating health complications, yet plaintiffs in the case argue the agency failed to act to protect nearby communities from this threat.
