- Michigan Orphan Wells [Michigan]
- Description
- This data is visualized in the Michigan Orphan Wells Dashboard. Michigan's Orphan Well Program was created in 1994. Orphan wells are abandoned or improperly plugged wells for which there is no known solvent existing owner or operator. EGLE's Oil, Gas, and Minerals Division (OGMD) worked with the oil and gas industry for the passage of Act 308, P.A. 1994, which established an Orphan Well Fund within the Michigan Department of Treasury. OGMD utilizes the fund, paid for by revenue created by a severance tax on the oil and gas industry, to plug and remediate orphan well sites. Since the passage of Act 308 nearly 30 years ago, approximately 400 sites have either been plugged or remediated. As of October 1, 2022, Michigan had 447 documented orphan sites as well as additional associated orphaned facilities, piping, and contamination that remained to be addressed. Beginning October 1, 2022, OGMD began utilizing federal grant funds awarded under the Infrastructure Investment and Jobs Act (IIJA), 2021, also known as the Bipartisan Infrastructure Law Section 40601, to provide additional financial assistance for the Orphan Well Program. The IIJA created three types of grants for states to apply for to help address orphan wells and orphan facilities on federal, state, tribal, and private lands. This data also includes state funded orphan well cleanups. The orphan well data is updated nightly. A NULL in a field means that the field does not have any value. EGLE makes every attempt to ensure data accuracy but cannot guarantee the completeness or accuracy of the information contained within this dataset.
