There has been significant momentum behind natural gas extraction efforts in the United States, with many states embracing it as an opportunity to create jobs and foster economic strength. Natural gas extraction has also been championed as a way to move toward energy independence and a cleaner energy supply. First demonstrated in the 1940’s, hydraulic fracturing is now the predominant method used to extract natural gas in the U.S.
As domestic natural gas production has accelerated in recent years, however, the hydraulic fracturing process has come under increased public scrutiny. Concerns include perceived lack of transparency, chemical contamination, new techniques, water availability, waste water disposal, and impacts on ecosystems, human health, and surrounding communities.
The Hydraulic Fracturing in Michigan Integrated Assessment (IA) is the result of a unique partnership involving several University of Michigan units, industry representatives, environmental organizations, and state regulators that formed in 2012 in order to examine the multiple aspects of this gas extraction technique with an emphasis on impacts and issues related to the State of Michigan.
Upon release, the seven technical reports (available below) together formed the most comprehensive Michigan-focused resource on hydraulic fracturing.
Drawing upon the information provided by the technical reports, additional peer-reviewed materials, stakeholder input, and expert peer review, the final report offers an analysis of Michigan-specific policy options for high-volume hydraulic fracturing with a focus on three key issues: chemical use, water resources, and public participation.
Praised by both state regulators and environmental organizations, the IA was also cited by Governor Snyder in a March 2015 special message for its usefulness for evaluating options for hydraulic fracturing:

- Advisory Committee
An advisory committee composed of representatives from corporate, government, and non-governmental organizations provided input and advice reflecting the view of key stakeholder groups and to ensure the scope of study is relevant to decision makers. Committee members also provided data and input throughout the process, but decisions regarding content of project analyses and reports were determined by the U-M Report and Integration Teams.Valerie Brader – Senior Policy Advisory, Governor's Office of Strategic Policy, State of MichiganJames Clift – Policy Director, Michigan Environmental CouncilJohn DeVries – Attorney, Mika Meyers Beckett & Jones; Michigan Oil and Gas AssociationHal Fitch – Director of Oil, Gas, and Minerals, Michigan Department of Environmental QualityGregory Fogle – Owner, Old Mission Energy; Michigan Oil and Gas AssociationJames Goodheart – Senior Policy Advisor, Michigan Department of Environmental QualityTammy Newcomb – Senior Water Policy Advisor, Michigan Department of Natural ResourcesGrenetta Thomassey – Program Director, Tip of the Mitt Watershed CouncilJohn Wilson – President, TMGEnergy, LLC
- Public Comment & Peer Review
Stakeholder engagement was a key component of this integrated assessment (IA). The public was invited to provide input to inform the scope of the IA and comments on the draft IA report, and a webpage accepted comments throughout the entire IA project. The comments received were reviewed, organized, and shared with the researchers and Advisory Committee to aid in developing the IA plan and revising the final IA report.
In addition, a panel of subject area experts representing multiple disciplines completed a peer review of the draft IA report to evaluate the scientific credibility, rigor, and integrity of the assessment. The Final Integrated Assessment Report was prepared after careful consideration of the feedback received from the peer review panel, advisory committee, and public comments.Key points of engagement
- September 9, 2013 – A webinar after the technical reports were released included an overview of the project and question and answer session with several technical report authors. Watch the video, download the presentation (PDF), and review the attendee question and response summary (PDF).
- February 26, 2015 – Following release of the draft IA report, Graham held a public webinar with several authors of the draft report. Watch the video, download the presentation (PDF), and review the attendee question and response summary (PDF).
