Virginia pulp mill gets new rules for air pollution, but the EPA still has to approve them

US environmental regulators approved a change to an operating permit for a pulp and paper mill in Virginia. The change updates how the mill limits air emissions that cause haze.

This document is a small step in a long process. State environmental agencies often update permits for industrial facilities. But these updates still need federal approval to become part of the state's official plan for clean air. This means the US environmental regulators are still the final authority on what counts as a valid pollution limit.
