The lawsuit by Save Carbon County against Stronghold Digital Mining Inc filed in state court in Philadelphia, also names Pennsylvania as a defendant. The group, a nonprofit whose members live near the bitcoin mine, is seeking compensatory and punitive damages from the company, and an order directing the state to stop allowing the pollution to continue.

The group said Stronghold has created a public and private nuisance by releasing mercury into waterways and spewing harmful chemicals like sulfur dioxide into the air from an aging power plant it bought to power its energy-thirsty operations.
