The U.S. Environmental Protection Agency has finalized a rule to reduce hazardous air pollutants and cancer risk; the standards apply to over 200 U.S. chemical plants. The new emissions rule requires fenceline monitoring of air pollutant levels around a facility's perimeter.
The ruling announced Tuesday targets plants involved in the production of highly toxic chemicals possibly linked to cancer like ethylene oxide (EtO) and chloroprene. These new standards are expected to total around $1.8 billion in compliance costs for the chemical industry.
