ECOND AMENDED NEPA DETERMINATION: (See attached original and First Amended Determinations, dated February 8, 2022, and February 24, 2025, respectively). This Second Amended Determination follows the approval of an extended period of performance and removal of two teaming partners to develop a catalyst-enabled, economical technology that will reduce emissions from ventilation air methane associated with coal mining, in progress under the Reducing Emissions of Methane Every Day of the Year (REMEDY) program. Specifically, the project team will (1) produce and acquire catalyst material to include in scale field test of reactor technology, (2) finalize development of machine-learning sensor and feedback controls, (3) develop a small-scale reactor system for field testing to meet heat recovery, sensing, feedback, and emission standards, and (4) identify needed adjustments for future iterations of the system.
