; (J) set performance standards based on modern procedures and equipment that minimize gas loss from— (i) downhole maintenance; (ii) liquids unloading; (iii) well completion; and (iv) such other procedures as the Secretary determines appropriate to reduce and prevent gas release; (K) require all operators to have leak detection programs with regularly scheduled inspections that assess the entire covered operation using an infrared camera or other equipment with methods that provide overall at least equivalent sensitivity and effectiveness in detecting leaks on a timely basis; (L) require any leaks found to be repaired promptly, and in any case not later than 4 weeks after the discovery of the leak, except where exceptional circumstances warrant an extension of not more than 8 additional weeks; and (M) require recordkeeping for— (i) equipment maintenance; (ii) leak detection and repair; (iii) venting events; (iv) flaring events; and (v) such other operations as the Secretary determines appropriate to reduce and prevent gas release. (b) Gas measuring, reporting, and transparency requirements (1) In general The Secretary shall, not later than one year after the date of enactment of the Methane Waste Prevention Act of 2019, issue regulations requiring each operator to measure and report, with respect to all gas subject to the mineral leasing laws, all such gas produced, consumed on site, or lost through venting, flaring, or fugitive releases. (2) Measuring and reporting requirements To account for all gas referred to in paragraph (1), the Secretary shall issue regulations requiring each operator to— (A) measure all production and disposition of gas with such accuracy that fugitive gas releases can be calculated; (B) install metering devices to measure all flared gas; and (C) report to the Secretary the volumes of gas measured under the requirements described in subparagraph (A), including— (i) all new measured values for production and disposition, including vented and flared volumes
