Yesterday the Senate Homeland Security and Government Affairs Committee (HSGAC) failed to take action to protect the public, instead choosing to let millions of Americans remain at unnecessary risk of chemical disasters. The committee members chose to gut a House-passed bill that would have reduced the consequences of a terrorist attack on chemical plants and water treatment facilities. The committee also refused to consider a similar bill from Sen. Frank Lautenberg (D-NJ). Both the House bill and the Lautenberg bill would have protected workers and communities by driving the adoption of safer, cost effective technologies that eliminate the threat of an intentionally released cloud of poison gas from a chemical plant.

A Texas-based deepwater drilling contractor has filed a lawsuit in federal district court, seeking to block the Obama administration’s latest effort to temporarily halt new offshore drilling operations while the Department of the Interior investigates safety and technology concerns in light of the April 20 explosion of BP’s Deepwater Horizon oil rig. Ensco Offshore argues in their July 20 suit that the drilling suspension issued by the Interior is “substantially the same” as an earlier moratorium that was struck down in federal district court.
