Hazardous waste plants must now control pollution during startups and shutdowns
What happened
US environmental regulators are tightening rules for hazardous waste incinerators and industrial boilers. These facilities will no longer get a free pass to pollute during their startup, shutdown, and malfunction periods.
Why it matters
Industrial facilities often emitted hazardous air pollutants without penalty during their most volatile operating times. This rule change means they must now install controls or change practices to limit pollution even when equipment is starting up, shutting down, or breaking.
The signal
Watch for industry lawsuits challenging the new standards, especially around the cost of compliance for older facilities.
