About
The Orphan Wells Mitigation Fee Enterprise Fund is the State of Colorado’s enterprise that oversees an industry-funded orphan well program with the highest level of environmental protections. The Enterprise uses fees from the oil and gas industry to plug and abandon orphan wells and reclaim orphan well sites. The Enterprise was established by SB22-198. The Commission adopted rules implementing SB22-198 in the June 2022 Orphan Wells Mitigation Enterprise Fee Rulemaking. Those rules are effective July 30, 2022.
The Commission established an Annual Mitigation Fee paid by industry that is expected to generate initially $10M annually, and is responsive to address orphan wells in the state of Colorado and is effective August 1, 2022. The fee will be revisited annually, allowing the funding to increase or decrease depending on the needs and anticipated scale of future orphan well work. The Enterprise Fund is in addition to the $10 - 15 million Colorado expects to spend annually for the next eight years from the Federal Infrastructure Investment and Jobs Act. In total, the federal funds and the orphan well enterprise funds will likely total $100 - $115 million over the next five years, which is unprecedented and will be totally paid for by industry and the federal government.
