The Oklahoma Sierra Club and Public Justice filed a federal lawsuit Tuesday against three Oklahoma energy companies, accusing them of using wastewater injection wells that are contributing to the state's sharp rise in earthquake activity. The lawsuit, filed in federal court in Oklahoma City, asks the court to "reduce, immediately and substantially," production waste from Devon Energy Corp., Chesapeake Energy Corp. and New Dominion LLC. It also asks for the companies to "reinforce vulnerable structures" that could be affected by large earthquakes.
