"The Trump Administration's first one hundred days have been historic. The American public made themselves heard last November, and we are delivering on this mandate. Promises made, promises kept. At EPA, we are doing our part to Power the Great American Comeback. To mark this momentous day, we are proudly highlighting 100 environmental actions we have taken since January 20th to protect human health and the environment," Zeldin said in a video post, the prepared remarks of which were obtained by Breitbart News ahead of its release.

The EPA chief touted 100 significant environmental actions the agency took to fulfill what the administrator has long believed as the "core mission" of the agency. President Richard Nixon, a Republican, established the agency in 1970, giving the agency two missions: promoting clear air and water as well as reducing pollution from waste disposal and other hazards. Zeldin has said that the agency has refocused on the main mission of ensuring clean air and water instead of pushing onerous regulations in furtherance of the "climate change religion."

Zeldin's actions to cut regulations while protecting the environment are no small task.

In a statement, Taylor Rogers, an assistant press secretary for the Trump White House, said that the Trump administration and Zeldin have "taken monumental steps to quickly remove toxins from our water and environment, provide clean land for Americans, and use common-sense policies to Power the Great American Comeback."

"Here are a few top highlights: To protect our nation's waters, we updated water quality standards for 38 miles of the Delaware River to protect critical fish species and keep the river clean. We approved a plan to further restore and protect the Long Island Sound over the next decade. We also developed a method to detect 40 different PFAS in surface water, ground water and wastewater," Zeldin remarked.

He continued, "Our team completed one of three in-water cleanups at the Lower Duwamish Waterway Superfund Site and revised the 2025 Idaho Water Quality Performance Partnership with the Idaho Department of Environmental Quality. To ensure clean air for all Americans, we demanded answers from an unregulated geoengineering start-up, Make Sunsets, that has been launching sulfur dioxide into the air to receive 'cooling credits.'"

"We approved 25 State Implementation Plans, 16 of which were backlogged from the previous Administration, so that environmental requirements go into effect faster, and we addressed air quality at the border with air filters and monitoring. To provide clean land for Americans, we have fully cleared, or cleared a portion of, four Superfund sites to date," he said.

The EPA administrator in March he said that he would move to clear the hundreds of backlogged cases to clear air, saying that the Biden administration has ignored these cleanup plans due to its fixation on "ideological pursuits."
