Clean up smog-forming pollution from Pennsylvania's power plants

I am writing in support of cleaning up unhealthy, smog-forming nitrogen oxide pollution from coal fired power plants in Pennsylvania (docket # EPA-HQ-OAR-2020-0351). These facilities are the largest source of smog-forming pollution on the East Coast and jeopardize the health of millions of Americans who live downwind. Please approve Maryland's petition to require these facilities to run their pollution controls every day of the smog season.
