Environmental groups on Wednesday filed a lawsuit challenging a rule that exempts large feed operations from reporting data on air emissions from animal waste.
Earthjustice, Waterkeeper Alliance, Sierra Club, Humane Society of the United States, Environmental Integrity Project and the Center for Food Safety are suing the U.S. Environmental Protection Agency (EPA) over the exemption, created in 2008 before George W. Bush left office.
The EPA rule exempts large concentrated animal feeding operations, or CAFOs, from disclosing emissions data on ammonia and hydrogen sulfide, defined as hazardous substances under public health, right-to-know statutes.
The EPA, under President Barack Obama, agreed to re-evaluate the exemption after the coalition of environmental groups in 2009 petitioned the federal appeals court for the District of Columbia to review the rule.
The court mandated that EPA reconsider the exemption.
The lawsuit was filed because they said the EPA is taking too long to reconsider the exemption.
