  • CO2 Underground Injection Regulations: Selected Differences for Enhanced Oil Recovery and Geologic Sequestration
    Angela Jones, Congressional Research Service

    Underground injection and storage of carbon dioxide (CO2) has been proposed to help mitigate CO2 emissions into the atmosphere from stationary sources burning fossil fuels. In the United States, CO2 is injected into geologic formations for both enhanced oil recovery (EOR) and, in more limited instances, intended for geologic sequestration. The presentation will provide an overview of select differences between federal regulations for CO2 injection for EOR and regulations for injection for geologic sequestration, with a focus on the U.S. Environmental Protection Agency’s Underground Injection Control and Greenhouse Gas Reporting programs.

  • Regulatory Elements Identified for a Class VI Primacy Program
    Lily Barkau, Wyoming DEQ, Water Quality Division

  • A Permitting Framework for Class VI Geologic Sequestration Wells
    Shari Ring, Cadmus Group

    Permitting of carbon dioxide (CO2) GS wells involves a rigorous evaluation of the site geology, the predicted subsurface behavior of the CO2 plume, and the well to ensure that a proposed site can receive and confine the CO2. A holistic permit application review process—implemented by a team of geologists, hydrogeologists, modelers, and others—supports the development of protective Class VI permits. This presentation will provide an overview a Class VI permit application review.

  • EPA’s Class VI Permitting Tools and Program Updates
    William Bates & Molly McEvoy, U.S. Environmental Protection Agency

    The U.S. Environmental Protection Agency (EPA) finalized federal regulations for the newest Underground Injection Control (UIC) well class, Class VI, for geologic sequestration of carbon dioxide in 2010. Over the past couple of years, EPA has observed a significant increase in interest in Class VI wells due to financial incentives, such as the IRS 45Q tax credit, and the environmental benefits associated with reducing the amount of carbon dioxide emitted to the atmosphere. 

    In response to increased interest from industry to inject carbon dioxide for deep storage and enhanced hydrocarbon recovery, EPA is drawing from lessons learned during EPA’s Class II permitting process improvement exercise and Regional permitting experience to facilitate expeditious Class VI permitting. EPA is utilizing existing resources and developing new tools to address its permitting responsibilities under the UIC program. 

    This presentation will focus on EPA’s UIC Class VI guidance documents and quick references – published on EPA’s website to assist permit applicants with preparing application materials and UIC permitting authorities with evaluating and permitting potential projects – as well as newly released tools and additional tools under development at EPA. EPA will continue to release tools to state agencies and the public as they become available.

Angela Jones | Analyst, Environmental Policy | Congressional Research Service (CRS)

Angela Jones is an Analyst in Environmental Policy at the Congressional Research Service (CRS), which provides non-partisan research and analysis to members of Congress, their staff, and Congressional committees.  Her policy portfolio includes Underground Injection Control policy, Subtitle C of the Safe Drinking Water Act, and carbon capture and storage issues. Prior to CRS, Ms. Jones provided environmental policy and regulatory analysis in the private consulting and non-profit sectors. She holds a Master’s degree in Environmental Policy and Natural Resources Management from Indiana University School of Public and Environmental Affairs and a Bachelor’s degree from Duke University.

Lily R. Barkau | Groundwater Section Manager, Water Quality Division | Wyoming Department of Environmental Quality

Lily R. Barkau is the Groundwater Section Manager of the Water Quality Division at the Wyoming Department of Environmental Quality.  She oversees the Underground Injection Control Program, CERCLA cleanup projects in the Federal Facilities Program, Groundwater Pollution Control Legacy Sites and special projects associated with groundwater issues across the state. 

She received a bachelor's degree from Wichita State University and a master's degree from Colorado School of Mines.

Shari Ring | Senior Associate | Cadmus Group

Shari Ring is a Senior Associate in Cadmus’ Arlington, VA office with 30 years of experience supporting EPA’s ground water protection efforts, particularly for the Underground Injection Control Program. She heads Cadmus' UIC support team, and led the multidisciplinary teams that reviewed several Class VI permit application reviews in support of USEPA’s regional offices. She has supported all of the federal UIC Program’s rulemakings and other significant initiatives for 3 decades, including supporting EPA as it developed the Class VI geologic sequestration rule and preparing a series of guidance documents and technical background papers.

Bill Bates | National Program Manager | US EPA, Office of Groundwater and Drinking Water

Bill Bates is a national program manager within U.S. Environmental Protection Agency’s Office of Groundwater and Drinking Water, where he oversees activities associated with the Underground Injection Control and Source Water Programs. He was worked for the U.S. EPA for 16 years. Through the course of his tenure he as a served as a permit writer, an enforcement officer, and as subject matter expert on oil and gas related injection practices. Bill received his master’s degree in Earth and Environmental Sciences from the University of Illinois at Chicago and his bachelor’s degree in Natural Sciences from the University of Akron.

Molly McEvoy | General Engineer, UIC Program | US EPA

Molly McEvoy is a General Engineer in the Underground Injection Control (UIC) Program for the United States Environmental Protection Agency (EPA) out of the headquarters office in Washington, DC. Molly joined the agency in July 2019 and currently serves as the staff lead for Class VI program activities at EPA headquarters. Prior to joining EPA, Molly worked as an environmental engineer for an environmental contractor. She received a bachelor’s degree in geophysics and mathematics from SUNY Geneseo in 2013 and a master’s degree in civil engineering, with a concentration in environmental and water resources engineering, from the University at Buffalo in 2016.

Professor Andrew Garnett | University of Queensland (Australia)

Professor Andrew Garnett has over 30 years’ international experience with oil majors in conventional and unconventional hydrocarbon exploration, appraisal and development projects. Prior to joining The University of Queensland in 2012, he consulted widely on oil and gas developments, most notably those with high greenhouse gas emissions footprints and worked on the 500MW, 60 MT ZeroGen IGCC and CCS Project as Manager for Carbon Transport and Storage and ultimately as CEO and Project Director. He currently leads large multi-disciplinary UQ research programs contributing to future energy transitions through natural gas and through carbon abatement. This research supports industry, government and other stakeholders to assure supply, enable lower carbon baseload power and deliver significant benefits for regional communities. He is a reviewer for the International Energy Agency’s World Energy Outlook (natural gas and carbon capture and storage).
