Environmental groups file second challenge to California leases. Sierra Club and the Center for Biological Diversity filed suit claiming the U.S. Bureau of Land Management ("BLM") violated the National Environmental Policy Act ("NEPA") in allegedly failing to assess the alleged environmental impacts of hydraulic fracturing before leasing federal lands for development in Monterey, San Benito, and Fresno counties. A federal magistrate judge recently ruled that BLM failed to consider the potential for hydraulic fracturing to impact groundwater and endangered species under NEPA in connection with BLM leases of other federal land in Monterey and Fresno counties. The court has not yet decided on a remedy, leaving it to the parties to reach a proposed settlement or to brief the remedy issues. In the new action, the NGOs are arguing BLM allegedly similarly failed to consider the same environmental impacts.
