[2] Coal was delivered to the Chalk Point generating station by CSX Transportation trains via the Herbert Subdivision, a former Pennsylvania Railroad (PRR) line.

The electrical output of Chalk Point Generating Station is dispatched by the PJM Interconnection regional transmission organization.

[6] In 2006 the U.S. Environmental Protection Agency (EPA) reported that the Chalk Point plant emitted over 21 lbs/MWh of sulfur dioxide (SO2), ranked as the 24th largest such emitter in the United States.

[12] In August 2018, the Maryland Department of the Environment (MDE) required three generating stations across the state, including Chalk Point, to meet current federal wastewater standards (effluent guidelines) by November 2020.

The coal-fired units at these plants discharged arsenic and mercury to their respective receiving waters, as allowed by 1980s-era pollution standards under expired permits.
