CNX Expands Historic Public-Private Transparency Collaboration with Shapiro Administration to Include Radiation Monitoring and Disclosure

Building on the nation's first-of-its-kind program, CNX will now continuously monitor and publicly disclose ambient gamma radiation levels at well pads and certain produced water facilities and expand disclosure of radiation surveys on waste leaving its sites — going beyond regulatory requirements to give Pennsylvanians even more real, site-level data.

PITTSBURGH, Sept. 17, 2026 /PRNewswire/ -- CNX Resources Corporation (NYSE: CNX) today announced the next evolution of Radical Transparency, its first-in-the-nation public-private environmental monitoring and disclosure collaboration with Governor Josh Shapiro and the Pennsylvania Department of Environmental Protection (DEP). As part of this program update, CNX will add continuous ambient gamma radiation monitoring at its unconventional well pads and certain produced water facilities and expand its public disclosure of radiation levels associated with waste leaving its operating sites — all shared with DEP and the public with the same open, real-time approach that has defined the collaboration since it launched in 2023.

Since Governor Shapiro and CNX signed the historic Statement of Mutual Interest in November 2023, the collaboration has grown from a commitment to disclose air and water quality data and drilling chemicals on a 24/7 basis to also include the most intensive independent study of unconventional natural gas wells in the nation. The partnership also helped inform DEP rulemaking requiring broader chemical disclosure across the industry. Today's announcement extends the same standard of site-level, third party-verified data to radiation monitoring.

Onterris, formerly Montrose Environmental Group, is an accredited third-party environmental services provider with decades of experience in scientific testing and regulatory compliance across air, water, and radiological monitoring. Onterris brings the same independent rigor to CNX's radiation protection data as Clean Air Engineering applies to air quality monitoring under the program.

Under the expanded program, CNX will:

• Install continuous ambient gamma radiation monitoring at or near its unconventional well pads and certain produced water facilities, covering all phases of well pad development from drilling through production. Raw data will be collected by Onterris and provided to CNX and DEP simultaneously, with quality assurance and quality control performed under a dedicated QA/QC plan. The data will also be shared with the public in real time on the CNX Radical Transparency website.
• Expand public disclosure of waste transportation radiation surveys consistent with CNX's Comprehensive Radiation Protection Plan (CRPP). CNX already surveys the radiation level of waste leaving its sites before disposal; it will now disclose that daily survey data publicly, updated monthly, from drilling to production. CNX also conducts semiannual desktop reviews and annual on-site inspections of every waste handling facility it approves to receive its waste.

"Radical Transparency was never meant to be a program with an end date — it's how we intend to manage our business moving forward, providing the public and policymakers the data needed to make informed decisions about the nature of natural gas development in Pennsylvania, and that means it must continue expanding and growing into new areas," said Alan Shepard, President and CEO of CNX. "Just as we've done with air and water quality, we're going to put actual, site-level radiation data in front of the public and DEP rather than allow questionable studies and speculation to drive the narrative on this important issue. These are voluntary commitments that go beyond what any regulation requires of us, because our communities deserve real data, not guesswork, about the operations happening near where they and we live and work."

CNX notes that these commitments are voluntary and go beyond the company's existing compliance obligations under state and federal law. As with the rest of the Radical Transparency program, the goal is to provide communities, regulators, and elected officials direct access to site level data and facts – rather than relying on assumptions or modeling.
