EPA says it’s investigating allegations that Chinese companies were responsible for dumping pollution in U.S. environment

The Environmental Protection Agency (EPA) said Tuesday it’s launching an investigation into alleged Chinese companies dumping pollution into U.s. waters.

In a statement, the EPA said it will take appropriate action, including issuing warnings or fines.

The agency did not say how many Chinese companies might be involved in the alleged dumping.

The EPA has been at the center of a series of international lawsuits alleging China’s companies have been dumping pollution on U. s waters, including a lawsuit filed last month in California that claims the agency failed to properly enforce a 2012 Clean Water Act rule banning the dumping of toxic substances.

The court ruling was a victory for China, which has said the court ruling is invalid and is seeking a new trial.

The lawsuit also said the EPA failed to take steps to halt Chinese companies from dumping toxic chemicals in the U. S. from 2010 through the mid-2020s.

China has denied the allegations.
