High court labels EPA implementation 'unlawful'

摘要

The U.S. Supreme Court handed manufacturers, including power plants, a defeat in upholding the Environmental Protection Agency's (EPA) authority to set clean air standards without regard to cost. But the court also found EPA exceeded its authority in attempting to impose a new eight-hour ozone standard. It ordered EPA to reconsider how it sets ozone standards; the high court called the agency's existing implementation policy unlawful. Industry experts said revamping the process and issuing new rules could take a number of years.
