AQUIFER EXEMPTION COMPLIANCE SCHEDULE REGULATIONS

DOC Sends Out Public Notice of Proposed Regulations for Aquifer Exemption Compliance Schedule

The California Department of Conservation (DOC) has sent out public notice of proposed regulations for the aquifer exemption compliance schedule related to the Underground Injection Control (UIC) program managed by the Division of Oil, Gas, and Geothermal Resources. The public notice begins the formal rulemaking process and marks the beginning of a 45-day public comment period. The proposed regulations are necessary to ensure that the State’s federally-approved UIC program for Class II injection wells meets the requirements of the federal Safe Drinking Water Act, and protects public health, safety and the environment in an efficient manner.

These regulations were adopted on a temporary basis by emergency rulemaking on April 20. This rulemaking action is to complete the formal rulemaking process in order to keep these regulations in place.

Comments regarding the proposed regulations can be submitted until 5:00 p.m. on July 13, 2015 via email to UIC.Regulations@conservation.ca.gov; via FAX to (916) 324-0948; or via regular mail to the Department of Conservation, 801 K Street, 24-02, Sacramento, CA 95814, ATTN: Aquifer Exemption Compliance Schedule Regulations.

Comments will also be taken at two public hearings around the state:

Bakersfield – July 15, 4:00 p.m. – 7:00 p.m. Bakersfield Marriott at the Convention Center, 801 Truxtun Avenue.

Santa Maria – July 16, 4:00 p.m. – 7:00 p.m. Santa Barbara County Supervisors Hearing Room, 511 East Lakeside Pkwy.

Documents related to the Department of Conservation’s rulemaking efforts can be found here.

EMERGENCY RULEMAKING: AQUIFER EXEMPTION COMPLIANCE SCHEDULE REGULATIONS

On April 2, 2015, the Department of Conservation noticed its intent to propose the adoption of emergency regulations necessary to protect public health, safety and the environment, and to bring California’s Class II Underground Injection Control program into compliance with the federal Safe Drinking Water Act. This action was taken in accordance with Government Code sections 11346.1 and 11349.6 of the California Administrative Procedures Act. These regulations were approved by the Office of Administrative Law (OAL) on April 20, 2015, and are now in effect.

EPA Correspondence and Guidance Documents

On Friday, May 15, the Division of Oil, Gas, and Geothermal Resources of the Department of Conservation and the State Water Resources Control Board sent an update to the U.S. Environmental Protection Agency on the State agencies’ ongoing corrective review of underground injection well information. The objective of the review has been to identify wells that may have been improperly permitted to inject produced fluids into non-hydrocarbon producing, non-exempt aquifers. This update focuses particular attention on those wells that may have the highest risk to California aquifers from contamination due to oil and gas production.

Division, State Water Board, and US EPA Aquifer Exemption Workshops

Joint workshops conducted by the Division, the State Water Board, and the US EPA were held in Bakersfield and the L.A. Basin. These workshops were intended to provide a brief history of the State’s primacy delegation from US EPA, as well as an outline of the data requirements and process for requesting an aquifer exemption under the Safe Drinking Water Act. All three agencies provided short presentations regarding their specific role, and were available to answer general questions about the aquifer exemption application process.

Copies of the presentations by the three agencies are found below:

The link below is to a list of issued well permits that may currently have a corresponding well injecting into an aquifer potentially needing an aquifer exemption, pursuant to the US EPA’s request.
This list is best understood as a list of well permits, rather than wells. Wells can be proposed and permitted without ever being drilled or converted to an injection well. Even where a well has been drilled, it may already have been plugged and abandoned or issued other orders preventing injection. Determining the current status of the wells listed here is part of the Division’s February 6, 2015, response to the US EPA. This list was generated by identifying one or both of the following characteristics:
  • The permit is for a well located outside the productive limits of a field as those limits were identified in the State’s Primacy application to the US EPA;
  • The permit is for a well injecting within the productive limits but into multiple zones, one of which may not be exempted by the Memorandum of Agreement (MOA) with the US EPA. The Division acknowledges that many of these wells may not need an aquifer exemption, but a formal determination cannot be made until an evaluation, of the specific well(s) and injection zone(s), is completed.

Please note that the evaluation of these well permits has begun and the list continues to change. However, to be consistent with the US EPA’s letter to the Division dated December 22, 2014, and the Division’s response on February 6, 2015, the list contains the permitted wells into non-hydrocarbon producing zones as of August 2014, and a list of the enhanced oil recovery permitted wells as of October 2014. The Division will update the list periodically.

Update on the Memorandum of Agreement (MOA) with the United States Environmental Protection Agreement (EPA)

There are two competing versions of the September 29, 1982 Memorandum of Agreement between the Division of Oil, Gas and Geothermal Resources and the United States Environmental Protection Agency. California’s primacy delegation was made based on one or both of versions of this document. Some related documentation is also included.
