A lawsuit seeking an immediate halt to oil and gas wastewater injection at 2,500 wells across California took a positive turn for energy producers last week as Superior Court Judge George C. Hernandez denied plaintiffs’ motion for a preliminary injunction in a closely watched case challenging long-standing operations in the California oil and gas industry.

Plaintiffs in Center for Biological Diversity v. California Department of Conservation, California Superior Court, Alameda County, asked the court to throw out the emergency proposed rulemaking recently issued by the Division of Oil, Gas and Geothermal Resources (“DOGGR”). Additionally, the plaintiffs sought an injunction to stop injection wells operating in disputed aquifers.

Under the emergency proposed rulemaking, wastewater injections into non-exempt aquifers must be phased out by 2017. The proposed phasing-out period gives both DOGGR and the U.S. Environmental Protection Agency (“EPA”) the opportunity to determine whether some of the aquifers should be considered suitable places to inject produced water.

In finding no evidence of risk of imminent harm to protected non-exempt aquifers, the court concluded: “On this record, the threat of such contamination [of drinking water aquifers] is theoretical and speculative and plainly outweighed by the other harms [to the public, economy and industry] which are virtually certain to occur if an injunction issues.”
