Groundwater Monitoring: Oil & Gas Production Areas - SB4

Groundwater Monitoring for Oil and Gas Well Stimulation; and Activities Associated with Underground Injection Control (UIC)

ANNOUNCEMENTS

Notice of Public Comment Hearing: Proposed Aquifer Exemption

On August 20, 2015 the California Department of Conservation, Division of Oil, Gas, and Geothermal Resources (DOGGR), in consultation with the State Water Resources Control Board and the Central Coast Regional Water Quality Control Board, sent notice regarding a proposal to expand the current aquifer exemption designation for the Dollie sands of the Pismo formation in the Arroyo Grande oil field (in unincorporated San Luis Obispo county near the intersection of Ormonde Road and Price Canyon Road). Subject to approval by the United States Environmental Protection Agency, the proposed aquifer exemption would allow the State, in compliance with the federal Safe Drinking Water Act, to approve Class II injection into the identified area, either for enhanced oil recovery or for injection disposal of fluids associated with oil and gas production.

Hearing Information:

San Luis Obispo September 21, 2015 4pm-7pm
Courtyard Marriot
1605 Calle Joaquin Road
San Luis Obispo, CA 93405

Documents related to the Aquifer Exemption proposal, and information regarding how to submit comments can be found on DOGGR's website.

WELL OPERATOR GROUNDWATER MONITORING PLANS & REQUESTS FOR EXEMPTION FROM GROUNDWATER MONITORING

DOGGR interim well stimulation regulations require well operators to submit a groundwater monitoring plan as part of their well stimulation treatment notices. A well operator may alternatively request an exclusion from the requirement to submit a groundwater monitoring plan if the absence of protected water can be demonstrated. If protected water is shown to be absent, the Water Boards will issue a letter of written concurrence to the well operator. The written concurrence letter is to be submitted by the well operator in their well stimulation treatment notice. Supporting documentation provided by the well operators to the Water Boards is available on the DOGGR Well Stimulation webpage.

 

ELECTRONIC SUBMITTAL OF WATER QUALITY DATA FOR OIL & GAS GROUNDWATER MONITORING

Data collected as part of groundwater monitoring in the vicinity of a well subject to stimulation is required to be submitted in an electronic format compatible with the State Water Board’s GeoTracker database, following the guidelines detailed in Chapter 30 (commencing with Section 3890) of Division 3 of Title 23 of the California Code of Regulations.

Information regarding the electronic submittal of water quality data related to groundwater monitoring is included in our Getting Started guide.

Please contact the GeoTracker help desk at Geotracker@waterboards.ca.gov or (866) 480-1028 for technical questions and support.


PROPERTY OWNER REQUESTED WATER SAMPLING & DESIGNATED CONTRACTORS

SB 4 requires copies of DOGGR-approved well stimulation treatment permits and information on available water sampling and testing to be provided to every owner or tenant whose property line location is:

  • Located within 1,500 feet of the well that is to undergo well stimulation treatment, or
  • Within 500 feet from the horizontal projection of all subsurface portions of the designated well to the surface.

In accordance with Public Resources Code (Pub. Resources Code), the notified party may request water quality sampling and testing on any water well or surface water suitable for drinking or irrigation, paid for by the owner/operator of the oil or gas well. Water samples can be collected for baseline measurements prior to the start of the well stimulation treatment (Pub. Resources Code, § 3160, subd. (d)(7)(A)).

Follow-up measurements (after well treatment stimulation) shall be on the same schedule as any pressure testing of the treated well's casing. If the operator does not conduct a pressure test on the treated well casing following well stimulation treatment, a follow-up water sample shall be made available at least once. This sampling and testing program is subject to audit and review by the State Water Board.

All water quality data collected as part of the property owner requested water sampling will be submitted to the State Water Board in an electronic format that is compatible with the State Water Board GeoTracker information system.

The State Water Board is required to designate one or more qualified independent third-party contractors to perform property owner requested water quality sampling and testing (Pub. Resources Code, § 3160, subd. (d)(7)(B)). If you have been contacted by a well operator and would like to have your water sampled by a designated contractor, please visit our List of Designated Contractors for Water Sampling.

To apply to become a designated contractor for water sampling, or if you are interested in learning more details, please visit: How to Become a Designated Contractor for Water Sampling

Information regarding the electronic submittal of water quality data related to property owner requested water sampling is included in our Getting Started guide.

WATER BOARD REQUIREMENTS UNDER SB4

SB 4 requires the Water Board(s) to:

  • Consult with DOGGR during DOGGR’s development of regulations for well stimulation treatments.
  • Enter into a formal agreement with DOGGR regarding roles and responsibilities in the regulation of well stimulation treatments.
  • Designate one or more qualified third-party contractors that adhere to board-specified standards and protocols to perform property owner requested water quality sampling and testing.
  • Audit and review sampling and testing conducted by the third-party contractor(s).
  • Develop model groundwater monitoring model criteria by July 1, 2015, in consultation with DOGGR and other stakeholders that outline the approach to be implemented for either well-by-well or regional scale groundwater monitoring.
  • Begin implementation of a regional groundwater monitoring program by January 1, 2016.

UNDERGROUND INJECTION CONTROL (UIC)

BACKGROUND

Injection wells, which carry and permanently place fluids underground, are a potential ground water contamination source if not properly sited, constructed and maintained. Injection wells are regulated by the United States Environmental Protection Agency (US EPA) under the authority of the Underground Injection Control (UIC) Program.

The UIC program defines six classes of wells according to the type of fluid they inject and where the fluid is injected. This categorization ensures that wells with common design and operating techniques are required to meet appropriate performance criteria for protecting underground sources of drinking water.

In California, wells that inject fluids associated with oil and natural gas production operations (Class II injection wells) are regulated by the Department of Conservation, Division of Oil, Gas, and Geothermal Resources (DOGGR) Underground Injection Control (UIC) Program.

A 1988 Memorandum of Agreement between DOGGR and the State Water Resource Control Board (State Water Board) called for DOGGR to consult with the State Water Board during its consideration of UIC project permitting so that the State Water Board could assist with the protection of water resources. The 1988 MOA defined the following:

  • DOGGR lead agency for Class II UIC Program oversight (enhanced oil recovery (EOR) wells, waste disposal wells, aquifer exemptions)
  • DOGGR to consult with the Water Boards during its consideration of UIC project permitting so that the State Water Board could assist with the protection of water resources.
  • Regional Water Boards lead agency for surface discharges (produced water disposal ponds)

The Governor’s Office has directed the State Water Board to assist DOGGR in the review of aquifer exemptions and other issues related to oil and gas wastewater disposal activities. In a February 6, 2015 letter to US EPA, DOGGR and State Water Board identified the approach to work together for more integrated oversight of the UIC program, including:

  • Ensure that aquifers to be used for wastewater disposal are properly exempted
  • Review proposed UIC project proposals submitted by well operators to ensure the protection of groundwater beneficial uses
  • Review existing UIC injection wells that may be injecting into aquifers that may not have been properly exempted

On March 9, 2015, US EPA forwarded a letter to DOGGR and State Water Board outlining agreed upon deadlines and milestones for implementing the February 6, 2015 DOGGR and Water Board plan.

AQUIFER EXEMPTION REVIEW

DOGGR will forward to State Water Board aquifer exemption application along with DOGGR’s review recommendations for the application. The State Water Board, in consultation with the appropriate Regional Water Quality Control Board, will review the aquifer exemption application using the evaluation criteria outlined below. The State Water Board and DOGGR will work towards reaching a consensus to determine if the aquifer exemption application contains sufficient documented evidence to meet the criteria for an aquifer exemption.

Previous Meetings

The State Water Board participated in a hearing of Senate Natural Resources and Water Committee to address issues about illegal injections occurred in underground water supplies that could be used as sources of drinking water or irrigation.

The California Natural Resources Agency, and Department of Conservation and community were also invited to testify

March 10, 2015 - Capitol Building in Sacramento, California
