Arizona Senate Majority Whip Frank Carroll (R-LD28) introduced a measure on Tuesday, urging the U.S. Congress to clearly define and limit the Environmental Protection Agency’s (EPA) regulatory authority. Carroll and his cosponsors argue that ambiguous federal power threatens jobs and economic growth in Arizona. The proposal, SCM 1004, was advanced by the Arizona Senate Republican Caucus earlier this week.
Carroll’s measure calls on Congress to affirm its role in setting national environmental policy and to draw explicit boundaries around the EPA’s authority under federal law. The memorial highlights that, under the Clean Air Act, the EPA is charged with setting and reviewing National Ambient Air Quality Standards (NAAQS) every five years to protect public health and welfare, but argues that compliance requirements have grown burdensome for businesses and workers.
“Americans deserve clean air, land, and water, but they also deserve an economy that can grow without unnecessary federal interference,” Carroll said in a statement distributed by the Arizona Senate Republican Caucus. He added that the measure urges Congress to ensure EPA regulations are “grounded in law and sound science” and do not impose undue economic restrictions.
In additional remarks included in the memorial, Carroll said he is seeking to define the limits of EPA authority to prevent what he described as regulatory overreach.
“I am working to clearly define the EPA’s powers to prevent regulatory overreach that negatively impacts Arizona’s economy,” Carroll said. “While the Clean Air Act allows for specific emissions regulations, the EPA must not exceed its authority or violate fundamental principles of separation of powers. By preventing bureaucratic overreach, we can protect both the environment and the economic opportunities Arizona families and businesses rely on.”
SCM 1004 directs the Arizona Secretary of State to transmit copies of the memorial to leadership in both chambers of Congress and all members of Arizona’s federal delegation. The measure notes that while the EPA’s mission is to enforce environmental laws as intended by Congress, concerns over overreach have prompted states to call for clearer statutory limits on the agency’s powers.
Carroll’s push reflects broader national debates over the scope of federal environmental regulation. Critics of recent EPA proposals have warned that aggressive regulatory action could affect industries including agriculture, energy production, and water resources. Such debates have included congressional hearings examining the consequences of EPA actions on sectors like American agriculture and rural economies.
The memorial challenges key assumptions underlying EPA policies formulated under Democratic administrations and proponents of policy such as the ‘Green New Deal’, stating:
“Greenhouse gases like CO2 and methane are not acutely toxic like other hazardous pollutants and have no direct impact on human health;”
“There is no consensus as to whether global warming is a problem or a benefit or how current temperatures fit into the broader climate context;”
“Global temperatures, droughts, floods and hurricanes have not increased with increasing global CO2 emissions;”
The memorial further refutes the EPA’s authority regarding greenhouse gas emissions, stating directly: “The EPA has no explicit statutory authority to regulate greenhouse gases.”
The memorial comes amid ongoing statewide discussions about the balance between environmental protection and economic growth, with Arizona lawmakers questioning the appropriate reach of federal agencies in areas ranging from air and water quality to land use and energy development.
SCM 1004 was co-sponsored by a group of Republican Arizona Senators, including Hildy Angius (R-LD30), David Gowan (R-LD19), Kevin Payne (R-LD27), Janae Shamp (R-LD29), and Thomas “T.J.” Shope (R-LD16).
President Trump has certainly shaken up, if not severely damaged, the climate hoax and Green New Scam in just 10 short months. Here’s a list of his 10 top climate-related accomplishments for which we should all be thankful this holiday season:
The Environmental Protection Agency (EPA) has proposed to end the government’s “scientific” basis for the climate hoax by rescinding the Obama EPA’s 2009 illegal and incorrect determination that emissions of greenhouse gases endanger the public welfare. As part of this effort, the Department of Energy issued a report by top climate scientists concluding that U.S. greenhouse gas emissions will have no detectable effect on global climate change.
President Trump, again, pulled the U.S. out of the 2015 Paris Climate Accord, an unconstitutional effort by Presidents Obama and Biden to adopt a United Nations treaty without ratification by the Senate.
The One Big Beautiful Bill Act terminated hundreds of billions of dollars of the climate-related “Green New Scam” spending of the (so-called) Inflation Reduction Act, including all subsidies for electric vehicle purchases.
President Trump has directed his administration to reduce Green New Scam spending that survived the One Big Beautiful Bill by means of bureaucratic review, red tape and delay. The rent-seeking and piratical thieves who want to steal from taxpayers played hardball to save some of their ill-gotten gains. The President is now showing, rather impressively, that he can play hardball right back.
President Trump signed into law a bill terminating California’s electric vehicle mandate. Greens had tried to mandate EVs in California to force carmakers to only make EVs for the entire nation. Thanks to the President, that will not happen in the foreseeable future.
The EPA scored an appellate court victory in its effort to reclaim $20 billion in Biden EPA Green New Scam panic spending made infamous by the Project Veritas video, “We’re Throwing Gold Bars Off the Titanic.”
President Trump halted a number of offshore wind projects and cut funding for many others. There are other projects that deserve to be terminated, such as the largest U.S. offshore wind farm being built by Virginia’s Dominion Energy, but a great start has been made so far.
Stunningly, President Trump stopped cold a U.N. treaty to implement a global tax on shipping emissions by threatening would-be signatories with tariffs. This treaty would have been the first global climate tax.
President Trump boycotted and sent no delegation to the United Nations climate conference (COP-30) in Brazil, rendering the annual meeting even more confused and meaningless than it usually is.
President Trump delivered a blistering speech to the United Nations blasting the climate hoax for about 15 minutes or so. The President summed up his views on climate in this one memorable sentence: “The carbon footprint is a hoax, made up by people with evil intentions and they’re heading down a path of total destruction.”
That’s quite a list. But much is left to be done. Some of the big items are as follows:
The EPA must finalize its rescission of the endangerment finding and then successfully defend the rescission in the Supreme Court.
All the Green New Scam spending must be terminated as soon as possible. Every dollar spent is a dollar stolen from taxpayers and invested in making us more energy dependent on Communist China.
It is not enough to withdraw only from the Paris Climate Accord. President Trump must withdraw the United States from the 1992 parent treaty, the United Nations Framework Convention on Climate Change (UNFCCC).
And it would be really awesome if President Trump also withdrew the U.S. from the 1987 Montreal Protocol, the bogus treaty allegedly addressing the imaginary “ozone hole.” That treaty, the follow-on Kigali Amendment ratified during the Biden administration, and language in the American Innovation and Manufacturing Act of 2020 signed by President Trump, has only been used to make refrigeration and air conditioning pointlessly more expensive.
I heard Al Gore tell a group of conservatives in January 2006 that the real purpose of the Montreal Protocol was to demonstrate that a global environmental treaty could be implemented. That “success” was then subsequently used as precedent for the UNFCCC and its spinoff climate treaties, the Kyoto Protocol and Paris Climate Accord. The ozone hole hoax paved the way for the climate hoax and Green New Scam. It’s all been a multi-trillion-dollar fraud on American consumers and taxpayers.
America became great before these pointless environmental treaties. It has been greatly harmed and dangerously hamstrung by them since their ratification. If MAGA means anything, it means exiting international efforts to cripple the U.S. with junk science-based environmental treaties. And it would make a great Christmas present to the nation. Just a suggestion.
The U.S. Environmental Protection Agency (EPA) has filed a motion in a federal appeals court to vacate a Biden-era rule on fine particulate matter air quality standards, which was set to affect air quality regulations in Arizona.
In the motion filed in the U.S. Court of Appeals for the D.C. Circuit, Department of Justice attorneys representing the EPA told the D.C. Circuit that the agency’s 2024 rule change on fine particulate pollution standards is both legally and scientifically flawed and must be vacated. The motion noted that the “supplement” to the EPA’s 2019 Assessment of the NAAQS, or National Ambient Air Quality Standards, for particulate matter, “did not represent [a] full multidisciplinary evaluation of evidence’ for the underlying air quality criteria.” It added that the agency “lacks statutory authority to revise standards absent a thorough review.”
The PM 2.5 rule, finalized on December 15, 2024, was purported to strengthen protections against fine particulate matter pollution, which the EPA stated was linked to respiratory and cardiovascular health risks. Implementation was set to begin in 2025, with full compliance deadlines extending to 2031. The final rule revising the NAAQS lowered the annual primary PM 2.5 standard from 12.0 micrograms per cubic meter to 9.0 micrograms per cubic meter. The rule also established a new 24-hour PM 2.5 standard of 35 micrograms per cubic meter. The rule remains in effect until the court comes to a decision.
The consolidated lawsuits involved petitioners including the Commonwealth of Kentucky, et al., the Arizona Legislature, and the Arizona Chamber of Commerce, along with 21 other states and business groups against the U.S. Environmental Protection Agency, et al. The states and business groups challenged the rule, arguing it would impose billions in compliance costs on states like Arizona, potentially halting construction projects and job growth in areas struggling to meet the stricter standards.
The petitioners contended that the new limits would classify more areas as being in a state of nonattainment, leading to economic restrictions under the Clean Air Act. Oral arguments in the case were heard on December 16, 2024.
Arizona Senate President Warren Petersen hailed the EPA’s motion on X on November 26, 2025, crediting EPA Administrator Lee Zeldin with what he called a “BIG WIN FOR ARIZONA!” He added that the EPA, “just filed a motion in federal court to throw out Biden’s unlawful PM 2.5 rule that made it nearly impossible for parts of Arizona to ever meet clean-air standards — a rule that would have crushed jobs, construction, and our economy with billions in costs. The AZ Legislature & the AZ Chamber sued the Biden admin to stop this job-killing regulation. Our lawsuit helped bring about this reversal. Thank you, President Trump, for keeping your promise to cut red tape and protect Arizona families!”
BIG WIN FOR ARIZONA!

Adam R.F. Gustafson, Principal Deputy Assistant Attorney General, and Sarah I. Zafar, Trial Attorney in the DOJ Environment and Natural Resources Division, filed the EPA’s motion for vacatur. They wrote in part, “Implementation of the NAAQS is a complex process, which generates significant costs and reliance interests among States, local governments, and regulated parties.”
The DOJ attorneys also argued that the EPA, “should at least have considered the distinct costs associated with revising the NAAQS mid-cycle. EPA’s disregard of this relevant factor was arbitrary and capricious because it was unreasonable for EPA to read an exercise of discretionary authority as an invitation to ignore a relevant factor like cost.”
The case remains ongoing in the U.S. Court of Appeals for the D.C. Circuit.
In a decision advancing American energy dominance, the U.S. Environmental Protection Agency (EPA) announced a final rule granting the State of Arizona full primacy to control all classes of underground injection wells under the Safe Drinking Water Act (SDWA).
This approval positions Arizona as the primary regulator for protecting its underground sources of drinking water, while developing economic growth and innovation in clean energy technologies.
The move aligns with the EPA’s Powering the Great American Comeback Initiative, which emphasizes delivering clean and safe water to every American, restoring U.S. energy leadership, and empowering states to manage their own resources with local expertise.
By delegating authority to Arizona, the federal government recognizes the state’s unparalleled understanding of its unique water challenges and business landscape.
“Efficient and effective permitting is essential to bolstering American industry and unleashing energy dominance while protecting our nation’s water resources,“ said EPA Administrator Lee Zeldin. “States know their water resources best and understand the needs of their business community; entrusting them to take on permitting makes common sense. I am excited to see the economic growth that will be spurred by granting Arizona primacy to regulate underground injection under the Safe Drinking Water Act.”
The approval enables the Arizona Department of Environmental Quality (ADEQ) to oversee permitting and enforcement for all underground injection wells, including Class I wells for hazardous waste storage— ensuring these operations occur far below drinking water aquifers—and Class VI wells, critical for carbon capture and storage.
Following technical and legal review, the EPA confirmed that Arizona’s Underground Injection Control (UIC) program fully complies with SDWA standards. ADEQ will now handle authorizations and compliance monitoring with the EPA retaining oversight and permitting authority for wells on Indian Lands, except for Class II wells on Navajo Nation lands, because the Nation already holds primacy.
The move got the support from Arizona’s congressional delegation, emphasizing the significance of federalism and local priorities.
“Our Founding Fathers were clear in their commitment to states’ rights and a small federal government. Individual states must have the power to govern in the best interests of their own people. This ruling affirms that Arizona—not Washington bureaucrats—is best equipped to protect our water, foster economic growth, and ensure the well-being of our citizens. It is a key step in ensuring access to safe drinking water for Arizona communities for years to come. No one understands Arizona’s communities and resources better than Arizonans ourselves,” said Congressman Andy Biggs (AZ-05). “I am grateful to President Trump and EPA Administrator Zeldin for their commitment to slashing needless regulations and restoring authority to the states. This is a victory for federalism, for common sense, and for the people of Arizona.”
“Arizona understands our land, our water, and our energy needs better than anyone in Washington ever could. Granting primacy to our state of the Underground Injection Control program is a recognition that local expertise and innovation should lead the way,” said Congressman Juan Ciscomani (AZ-06). “It means that Arizona will now oversee the permitting for all underground injection wells, including Class VI wells essential for carbon capture and storage—a critical part of a secure and cleaner energy future, and Class I wells, which store hazardous waste far below drinking water resources critical for the health of all Arizonans. This step is a win for clean water, a win for responsible energy development, and a win for our economy.”
“I want to thank Administrator Zeldin and the Trump administration for recognizing that Arizona is best positioned to protect its underground sources of drinking water. This rule will allow us to provide clean and safe water for every Arizonan while bringing more and exciting economic opportunities to our great state,” said Congressman Abe Hamadeh (AZ-08). “This rule will strengthen Arizona’s ability to manage our future for our families.”
Arizona Governor Katie Hobbs also praised the decision as a pivotal achievement for the state saying, “Today’s decision is a major milestone for Arizona. By granting our state primacy over underground injection wells, the EPA is once again recognizing that Arizona is best positioned to protect its water and natural resources. This authority allows us to safeguard the integrity of our groundwater, while also supporting responsible economic growth and clean energy development. With this step, Arizona gains the tools to lead on sustainable environmental management and innovation for years to come.”

Since taking office in January, President Trump has worked hard to restore sanity in America. While the wins have been stacking up in many areas, perhaps his administration’s most notable efforts have been in its pushback against the junk science driving the climate agenda.
Along with executive orders in January and April to unleash American energy, Trump’s Environmental Protection Agency (EPA) announced that it would be reversing a Biden administration regulation that held Arizona accountable for the eighty percent of emissions in the Maricopa County nonattainment area that emanated from outside of the state—primarily from China and Mexico.
While all that is good news, the Trump administration delivered quite possibly the best news yet for American energy last month when the EPA released its plan on rescinding the Endangerment Finding. And it has the climate cult drowning in their tears.
What is the Endangerment Finding?
Back in 2009, the Obama administration declared carbon dioxide (CO2) as a pollutant that threatens public health and welfare under the Clean Air Act. Of course, this ignored the fact that CO2 is one of the most important ingredients for building and sustaining life on Earth. But the Obama administration was never known for exercising commonsense, so it gave birth to this controversial policy by relying on cherry-picked scientific data to justify a vast expansion of regulatory power at the EPA.
Since its inception, the Endangerment Finding has been used as the basis for many of the green scam regulations impacting Arizona’s economy. During both the Obama administration and the Biden administration, the EPA passed new regulations on vehicles, factories, power plants, and other mobile sources all based on the alleged dangers of CO2. These mandates have cost the U.S. economy over a trillion dollars, and here in Arizona, they have been responsible for higher energy prices and higher utility bills.
But if the climate cult gets its way, it wouldn’t stop there…
