On October 8, the California Department of Conservation (“DOC”) released a Renewal Plan for Oil and Gas Regulation (“Renewal Plan”) to revamp its regulatory program.  The goal of the Renewal Plan is to continue the DOC’s focus on environmental protection and public health, and it will shape the DOC’s regulatory decisions for the next two years.

The Renewal Plan contains four objectives: (1) regulatory overhaul, (2) new regulations for “new realities,” (3) modernization of data management, and (4) ensuring a high-quality workforce.  California’s Underground Injection Control (“UIC”) program is a key focus, and the Renewal Plan calls for a review of aquifer exemptions.  Exempt aquifers are those that are permitted to receive injection of Class II fluids (fluids associated with the production of oil and gas).  The review of exempt aquifers will ensure that Class II fluids are not being injected into potential drinking water sources.

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.”

On Thursday, May 7, 2015, two environmental groups filed a lawsuit seeking an immediate halt to oil and gas wastewater injection at 2,500 wells across California.

The suit, filed by the Sierra Club and the Center for Biological Diversity, claims that the state Division of Oil, Gas and Geothermal Resources (“DOGGR”) should be prohibited from letting companies pump produced water from their drilling operations into non-exempt aquifers.

DOGGR has repeatedly assured Californians that there has been “no contamination of water used for drinking or agricultural purposes related to underground injection by the oil and gas industry” and “no evidence has been found that underground injection has damaged sources of potential drinking water.”

Under DOGGR’s recently issued emergency proposed rulemaking, industry wastewater injections into non-exempt aquifers must be phased out by 2017.   However, the lawsuit calls for the injections to stop immediately. 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 — particularly those that also contain oil — should be considered suitable places to inject produced water. The EPA has the authority to declare an aquifer exempt from the federal Safe Drinking Water Act, making it eligible for wastewater injections.

On March 20, Senator Fran Pavley (D-Agoura Hills) wrote a letter to Governor Jerry Brown requesting that his administration immediately shut down approximately 2,500 underground injection wells.  The letter was signed by seven other legislators and urges that these wells must be closed until “all appropriate aquifer exemptions have been issued by the US EPA [Environmental Protection Agency] and investigations of groundwater contamination from these wells are complete.”

Senator Pavley’s letter comes in response to reports that California is out of compliance with the federal Safe Drinking Water Act (“SDWA”) underground injection control (“UIC”) program.  The SDWA prohibits injection of Class II wells into aquifers that are potential drinking water sources, called non-exempt aquifers.  Class II wells are those that dispose of waste water from oil and gas production.  The California Department of Conservation (“DOC”) is already addressing this matter, and has issued a notice of proposed emergency rulemaking to eliminate injection into non-exempt aquifers on April 2.Continue Reading Letter Urges Oil & Gas Wastewater Well Shut-Ins due to Risk of Groundwater Contamination; Regulators Stick to Rulemaking

On Friday, July 18, 2014, the Department of Conservation’s Division of Oil, Gas and Geothermal Resources (“DOGGR”) announced that it will review California’s Underground Injection Control (“UIC”) Program to ensure compliance with the requirements of the federal Safe Drinking Water Act (“the Act”).  DOGGR has primary authority under the Act to regulate underground injection wells, granted by the U.S. Environmental Protection Agency (“USEPA”).  DOGGR will conduct the review in conjunction with the USEPA, and expects the review to be completed in 12-18 months.

Originally enacted in 1974 and amended in 1996, the Act aims “to protect public health by regulating the nation’s public drinking water supply.”  (EPA, Safe Drinking Water Act).  The Act is applicable to well stimulation regulations because it has authority over ground water wells, excluding private wells that serve fewer than 25 people.  Protections are designed to prevent oil and gas production wastewater from being injected into drinking water aquifers.Continue Reading DOGGR to Review Well Stimulation Regulations to Ensure Compliance with Safe Drinking Water Act

At the end of last week, EPA and BLM each released draft requirements relating to fracking.  EPA released draft Underground Injection Control (UIC) Class II well permitting guidance for fracking activities that use diesel fuels.  BLM released draft rules requiring public disclosure of fracking chemicals used on public and Indian lands.

The EPA guidance applies…
