In California, most of the oil and gas reservoirs are conventional and thus found within layers of rock underneath the cap rock. There is a shale formation in California known as the Monterey Shale, however, this has not yielded much throughout the years unlike other shale formations across the U.S. One of the main concerns with fracking in California has been the risk of damage to groundwater and failure to comply with some of the requirements of the Clean Water Act and Safe Drinking Water Act.
Los Padres ForestWatch v. BLM, Case No. CV-15-4378-MWF (JEMx), 2016 WL 5172009, *1 (C.D. Cal. Sept. 6, 2016).
Case brought by environmental groups in the Central District of California alleging that the BLM improperly prepared a Final Environmental Impact Statement (EIS) by failing to address the impact of fracking or other well stimulation techniques on the environment under the resource management plan. The court ruled that BLM failed to take a hard look at the environmental impacts of the resource management plan since 25% of the wells in the plan would be using fracking techniques, and ordered the BLM to prepare a supplemental EIS to analyze the environmental consequences of fracking in the area.
Center for Biological Diversity v. BLM, 937 F.Supp. 2d 1140 (2013).
Case in the Northern District of California brought by environmental groups alleging decision by the Bureau of Land Management to sell 4 oil and gas leases for about 2700 acres of federal land. The court determined that BLM did not need to conduct thorough environmental impact analysis (EIA) for leases with no surface occupancy (NSO) provisions; did have to conduct thorough EIA for leases without mention of NSO provisions; BLM acted unreasonable when they prepared an EIA finding no significant impact for the non-NSO leases; and the leases in question satisfied the substantive provisions of the Mineral Licensing Act.
