Summary: This proposed rule would revise the production measurement regulations to establish meter proving, meter verification/calibration, and well test requirements after hurricanes and other vents beyond the control of the lessee. This rulemaking would eliminate some reporting burden on industry, and it would eliminate the need for MMS to grant waivers to the reporting requirements in certain situations. The proposed rule would also add new definitions providing clarity in the training regulations, which should lead to improved training of Outer Continental Shelf workers.
