Chemical companies are required by the Environmental Protection Agency’s Risk Management Plan rule, or RMP rule, to develop programs that help reduce the risk of accidents. There are 10,420 facilities nationwide that are required to submit plans under the rule. A growing threat to these facilities is coming into focus: climate change. More than 3,200 of these sites are in areas where natural hazards like storm surges, wildfires, and flooding are being exacerbated by global warming, according to a new report from the Government Accountability Office, or GAO, the U.S. Congress’ investigative arm. In January, more than 70 state and local officials sent a letter to the EPA administrator citing these facts and calling for stricter RMP rules.
