Chemical plants can no longer blame equipment failures for breaking air rules

US environmental regulators just tightened air pollution rules for chemical plants that make polyether polyols. These plants can no longer claim equipment malfunctions as an excuse for violating emission limits.

For years, chemical plants could pollute during an equipment breakdown and argue it was an accident. This rule change means they are now fully responsible for all emissions, even during malfunctions. It shifts the burden to the plant to prevent these failures or face fines.
