Data Centers

Contact Pima County about Data Center Zoning

Pima County is proposing zoning code changes to address data centers. There are several actions you can take. Learn more at Pima County website. Compare City of Tucson Data Center Zoning to proposed Pima County Data Center Zoning. One big difference that Third Act AZ noticed is the the buffers. City of Tucson requires 1/2 mile (2640 ft) buffer from residential and schools, but Pima County is only proposing 200 ft. Commercial buffers for City are 1,000 ft and County 100 ft. None of the zoning requirements take into account water usage for electricity generation. City of Tucson asks for 2 hours of backup storage electricity generation, but the County only specifies gas-fired generation.

Climate-Environment

By Nov. 2 – Tell the EPA not to repeal the Carbon Pollution Standards for Power Plants (Endangerment Finding)

Power plants are responsible for more than a quarter of U.S. climate pollution, and they also emit other pollutants that harm our air, water, and health. The Trump administration rolled back safeguards on most power plants’ climate pollution, and now it’s trying to strip the government’s authority to regulate the rest. Once again, this administration is putting our lives at risk to benefit polluters.

It may seem hopeless, but every comment becomes part of the Federal Record that can be used in lawsuits if needed in the future.

Choose how you want to act:

Submit your comment on Federal Register (40 CFR Part 60, [EPA-HQ-OAR-2025-0124; FRL-12674.1-01-OAR], RIN 2060-AX00)

Contact Governor Hobbs – Stop the sale or lease of state trust land (Skunk Camp) for mine waste

Urge Governor Hobbs to reject any proposal to sell, lease, or otherwise make available Arizona state trust land for Resolution Copper’s proposed massive mining-waste storage facility at Skunk Camp. The proposed facility would require approximately 8,200 acres of Arizona state trust land to permanently store nearly 1.4 billion tons of mining waste. A nearly 3-mile-long, 500-foot-high dam would hold this waste in the Dripping Springs Valley. A catastrophic failure would send toxic waste into downstream communities and the Gila River watershed.

Policy-Democracy

By October 12 – Tell Customs and Border Protection We Don’t Need 225 Miles of a Secondary Border Wall in AZ

Sky Island Alliance writes, “Over the past several months, the Trump administration has made it clear it won’t stop until our entire border is militarized and double walled — no matter the cost and destruction. This week, contractors felled a fourth old-growth cottonwood in Lochiel, Arizona, in the peaceful San Rafael Valley, then dragged it off with bulldozers.

As difficult as it may be, we must continue to speak out and create the record we’ll need when the political winds shift.”

CBP is now conducting additional outreach and seeking input regarding the construction of the secondary barrier in Cochise, Pima, Yuma and Santa Cruz Counties, Arizona.

Office of Management and Budget & National Science Foundation rules on Science Funding – Next Steps

Nearly half a million people like you provided comments to protect the integrity and funding of scientific research on Office of Management and Budget (OMB) proposed rules. The Senate pushed back, delaying the implementation of the rule.

Meanwhile the National Science Foundation (NSF) has proposed major changes to its procedures for awarding research grants that are inline with the devastating OMB proposed rules, and you provided comments on that.

Now it is time to contact your Members of Congress (MoC) to fight these rules:
