10 U.S. Oil Refineries Released Carcinogenic Benzene Above EPA Limits in 2019
EPA regulations dictate that benzene levels higher than nine micrograms per cubic meter over the course of a year require action on the part of the refineries, though they are not in violation of the law, The Guardian reported.
"The federal action level is intended as a benchmark to flag when emissions are higher than expected, so that facilities can look for the cause and take early action," an EPA spokesperson told The Hill.
"The federal action level is not based on an analysis of risk levels to the community — but rather on emissions from the facility.".
