A fire at the Husky Oil Refinery on April 26, in Superior, Wis. The Environmental Protection Agency is planning to rescind regulations that would require refineries and chemical manufacturers to disclose information about emergency plans and the root causes of disasters.

The EPA intends to block rules to prevent and respond to leaks, explosions and other disasters at chemical facilities and refineries around the U.S. That scares many people who live and work nearby.
