Several days before the explosion on the Deepwater Horizon oil rig, BP officials chose, partly for financial reasons, to use a type of casing for the well that the company knew was the riskier of two options, according to a BP document.

The concern with the method BP chose, the document said, was that if the cement around the casing pipe did not seal properly, gases could leak all the way to the wellhead, where only a single seal would serve as a barrier.

Using a different type of casing would have provided two barriers, according to the document, which was provided to The New York Times by a Congressional investigator.

Massey Energy is actively contesting millions of dollars of fines for safety violations at its West Virginia coal mine where disaster struck yesterday afternoon.

Twenty-five miners were killed and another four are missing after a explosion took place at 3 pm Monday at Massey subsidiary Performance Coal Co.’s Upper Big Branch Mine-South between the towns of Montcoal and Naoma. It is “the most people killed in a U.S. mine since 1984, when 27 died in a fire at Emery Mining Corp.’s mine in Orangeville, Utah.”

This deadly mine has been cited for over 3,000 violations by the Mine Safety and Health Administration (MSHA), 638 since 2009

"As recently as August, the largest lithium battery recycler in North America — Toxco — snagged a $9.5 million grant from the Department of Energy to build out battery recycling capacity in Ohio and pledged to provide “end of life management” for advanced vehicle batteries “in a safe and environmentally sound manner.” But this weekend multiple explosions and a major fire at the company’s Trail, British Columbia recycling facility can be fairly called bad advertising for that business."
