Thousands of miles of underground gathering pipelines in North Dakota are being mapped under new rules that require companies to report the locations to the state.
The North Dakota Legislature this year passed a broad measure that requires pipeline owners to submit the whereabouts of gathering pipelines and notify regulators when the lines are abandoned.
A $75 million fund from oil tax revenues also is being established pay for pipeline reclamation, if the pipeline's owner is not located.
The North Dakota Industrial Commission, headed by Gov. Jack Dalrymple, approved the rule changes last week.
Pipeline safety will also become a priority in the new year.
Gov. Dalrymple has named a 15-member advisory panel on pipeline safety in the wake of a massive spill in western North Dakota.
The group includes state and federal officials, oil and gas industry officials and engineers.
Dalrymple says the panel will provide recommendations for the best technology to monitor and control oil and gas pipeline systems in the state.
The move to review pipeline safety stems from a Sept. 29 oil pipeline rupture that spilled more than 20,000 barrels of oil across several acres of farmland near Tioga.
