The American Petroleum Institute (API) says the Environmental Protection Agency's proposed refinery rule would be "infeasible" to comply with and could actually increase pollution.
The EPA proposed restricting toxic air pollution from oil refineries in May, but industry groups say it would cost hundreds of billions of dollars to comply with.
The proposed rules would cut toxic emissions by 5,600 tons per year, according to the EPA.
“EPA’s proposed regulations could drive up costs and roll back environmental progress, forcing refineries to increase emissions by installing hundreds of costly new flare systems at a time when industry has been working with EPA to reduce flaring,” said Howard Feldman, API's director of regulatory and scientific affairs.
The petroleum institute filed comments with the EPA as the deadline expired Tuesday.
In their comments, the API explained the rules would provide "no real benefits at enormous costs" to every aspect of refining.
The proposed rule would require refineries to monitor concentrations of the chemical benzene, which has been linked to health problems. Refineries would also be required to upgrade emissions controls for storage tanks, emissions standards for delayed coking units and install flare restrictions.
