(3) Responsibilities The Consortium shall develop and implement a multiyear plan that— (A) identifies technical goals and milestones for the Consortium; and (B) facilitates data sharing for the purposes of— (i) bettering the understanding of methane emissions from the oil and gas sector; (ii) improving emissions detection, measurement, and mitigation capabilities, including assessing multi-tiered atmospheric measurements; and (iii) improving the understanding of methane quantification data analytics and machine learning platforms, including for calibration of measurements. (4) Reporting (A) In general The Secretary shall report on the Consortium’s activities to the appropriate congressional committees. (B) Initial report Not later than 18 months after the date of the enactment of this section, the Secretary shall submit to the appropriate congressional committees a report summarizing the activities, findings, and progress of the program under this section. The report shall include the following: (i) A review of LDAR technologies available to the oil and gas sector for the purpose of methane emissions measurement and mitigation. (ii) A summary of research gaps and priorities related to methane emissions detection, measurement, and mitigation capabilities. (iii) A description of the data sharing and cooperative activities that have been initiated pursuant to paragraph (3)(B). (C) Annual report Not later than 1 year after the date on which the report under subparagraph (B) is submitted and annually thereafter, the Secretary shall submit to the appropriate congressional committees a report summarizing the activities, findings, and progress of the program under this section.
