EPA’s stricter wastewater rules among reasons for additional coal-fired power plant retirements across PJM
In July 2021, the Environmental Protection Agency (EPA) announced new initiatives to strengthen wastewater pollution regulations for power plants that use steam to generate electricity and use coal as their fuel source. These initiatives are expected to affect 75 coal-fired power plants nationwide. The new rules would require these power plants to reduce their level of toxic metals, such as mercury, arsenic, and selenium, from plant wastewater before discharge into streams and rivers. Noncomplying plants had an October deadline to show state regulators how they plan to comply with the EPA’s regulations by 2028.
