US environmental regulators approve custom pollution controls for one factory

US environmental regulators approved a custom way for one Indiana factory to control air pollution. This means the factory can use its own specific equipment to reduce volatile organic compounds instead of standard methods.

This document shows how environmental rules can be tailored for individual companies. A factory can get approval to use its own specific equipment, as long as it meets the same pollution reduction goals. This offers flexibility for companies but requires regulators to assess each custom solution.
