Colorado Wildlife Federation On June 22, 2021 Colorado’s Senator Michael Bennet introduced a bill to fund orphaned oil and gas wells cleanup and to strengthen bonding requirements. The Oil and Gas Bonding Reform and Orphaned Well Remediation Act. There are more than 57,000 orphaned wells across the nation which threaten wildlife habitat, clean water and air, and human health. Senator Bennet’s bill will clean up these toxic sites and reform the antiquated bonding system so that in the future, oil and gas companies will have to pay for the cleanup instead of the US taxpayer.
