Today, Seneca Resources Company, LLC (Seneca), the Exploration and Production segment of National Fuel Gas Company (NYSE: NFG) (National Fuel or the Company), announced that it has executed an agreement with Project Canary to seek an independent responsibly sourced gas (RSG) certification for approximately 300 million cubic feet per day of the Company’s Appalachian production. In connection with this certification process, which will cover nearly one-third of the Company’s natural gas production, Seneca also intends to install continuous monitoring devices at three well pad locations, which will provide real-time, site-level emissions data. Project Canary’s proprietary ™ operational certification process is a recognized, comprehensive market leader for operators seeking RSG certification, with a focus on air, land, water, and community impacts. Overall, this certification process is expected to analyze more than 600 unique operational and environmental, social, and governance (ESG)-related data points on a per-well basis. “Sustainability, continuous innovation, and best-in-class environmental performance are embedded in our guiding principles and culture,” said David Bauer, President and Chief Executive Officer of National Fuel. “Seneca’s commitment with Project Canary seeks to independently verify our existing operational practices and further strengthen the Company’s ESG commitments. We are excited to work towards independent validation of our leading operational and environmental practices, many of which are standard across our Appalachia assets.” “Responsibly sourced gas certification is readily becoming a key piece of the independent analysis reviewed by investors, regulators, and customers to confirm top environmental performance” added Chris Romer, co-founder and CEO of Project Canary. “Seneca Resources is an early mover in working to gain certification for its operations and production, underscoring its commitment to strong environmental performance.”
