Tucson AZ large-scale data center zoning ordinance
Tucson, AZ · Effective September 4, 2026 · Tucson Unified Development Code Amendment — Large-Scale Data Centers (adopted August 5, 2026, effective September 4, 2026; Mayor and Council vote 6-1)
Tucson, Arizona's City Council voted 6-1 on August 5, 2026 to adopt strict zoning regulations for large-scale data centers, effective September 4, 2026. A 'large-scale data center' is defined as a facility exceeding 25,000 square feet or using more than 20 megawatts of power. Any such facility must go through a Planned Area Development (PAD) or Planned Community Development (PCD) rezoning process — the same high-level public review required for power plants — including a neighborhood meeting, a zoning examiner hearing, and a final vote by the Mayor and City Council. Additional restrictions include: a half-mile setback from residential areas, homes, schools, natural areas, washes, and open space; a 50-foot building height cap; and a prohibition on using city drinking water (potable water) for cooling. Data centers using more than 7.48 million gallons per month of water must submit water use plans to the Mayor and Council. City staff must report back within one year on implementation. Tucson had previously rejected the Project Blue data center annexation in 2025 over water and secrecy concerns.

Pima County AZ 120-day data center moratorium
Pima County, AZ · Effective September 22, 2026 · Pima County Board of Supervisors, Resolution adopting 120-day moratorium on new data center approvals in unincorporated county areas (September 22, 2026; vote 3-2)
The Pima County Board of Supervisors voted 3-2 on September 22, 2026 to formally impose a 120-day moratorium on approving new data center projects in unincorporated Pima County, Arizona. The moratorium is in effect while the county finalizes zoning code text amendments specifically addressing data centers; a permanent policy is expected to be adopted by December 10, 2026. The moratorium applies only to unincorporated county areas — not to the City of Tucson, which has its own separate zoning authority and enacted its own data center zoning ordinance in August 2026. Supervisors Andres Cano, Matt Heinz, and Board Chair Jen Allen voted yes; Rex Scott and Steve Christy voted no. The moratorium expires approximately January 20, 2027 (120 days from adoption).

Pima County Project Blue
Pima County, AZ · Enacted December 16, 2025 · Pima County, Ariz., Project Blue rezoning and development agreement (2025); Pima Cnty. Super. Ct. litigation
Pima County's role in Project Blue is an approval, not a restriction: after Tucson rejected the project in August 2025, the county board voted 3–2 to rezone and sell roughly 290 acres of county land, and on December 16, 2025 approved a development agreement with Beale Infrastructure to move the data center forward in unincorporated Pima County. Opponents sued under Arizona's open meeting law; a judge dismissed that suit in April 2026, with additional litigation filed in January 2026.

Arizona ACC cooperative large-load process (2026)
Arizona · Effective August 1, 2026 · Ariz. Corp. Comm'n — Large-Load Customer Service Agreement Process for Electric Cooperatives (Aug. 2026)
The Arizona Corporation Commission unanimously approved rule changes in August 2026 creating a standardised process for electric cooperatives to bring data centers and other large-load customers online without their existing members paying for it. When a large load arrives, the commission must now determine whether the application is in the public interest, whether its rates are reasonable, and whether other customer classes of the Arizona Electric Power Cooperative would be adversely affected. The co-op context is what makes this distinctive. Rural electric cooperatives are owned by their members and typically have small, fixed customer bases — a single hyperscale customer can represent a larger share of load than the entire residential membership, so an unfunded transmission or infrastructure commitment does not get diluted the way it would at a large investor-owned utility. Chairman Nick Myers framed the process as letting rural Arizona capture economic growth responsibly without being subsidised by other customers. The affected utilities are Mohave, Graham County, Trico, Sulphur Springs Valley and Duncan Valley Electric Cooperatives, together with the Arizona Electric Power Cooperative. Separately, the Arizona legislature responded to data centers in its 2026 session with a three-year pause on tax incentives.

Hualapai Tribe (AZ) hyperscale data center moratorium (2026)
Hualapai Tribe (AZ) · Effective September 14, 2026 · Hualapai Tribal Council resolution (approx. September 2026; prior opposition resolution approx. August 20, 2026)
The Hualapai Tribal Council in northern Arizona enacted a moratorium on hyperscale data center development within the Hualapai Reservation in September 2026, building on an opposition resolution passed approximately August 20, 2026. The Hualapai Nation controls nearly one million acres and shares a 108-mile border with the Colorado River. The Tribal Council stated that hyperscale data centers — which power AI and can consume hundreds of millions of gallons of water annually — pose 'a direct and severe threat to the tribe's sacred water, lands, environment and way of life.' The moratorium asserts that no outside entity or private developer may use, damage, or compromise tribal resources without the tribe's free, prior, and informed consent. Chairman Duane Clarke stated: 'Moving forward, we will always protect our air. We will always protect our land, and we will always protect our water.' The Colorado River Basin is facing critical water shortages, which the Tribal Council cited as a primary driver of the action.

Hualapai Tribal Council data center opposition resolution
Hualapai Tribe (AZ) · Effective August 20, 2026 · Hualapai Tribal Council Resolution No. 46-2026 (adopted August 20, 2026)
The Hualapai Tribal Council adopted Resolution 46-2026 on August 20, 2026, opposing construction of data centers within the Hualapai Reservation, the tribe's ancestral territory, and the broader Colorado River Basin. The Hualapai Tribe — headquartered at Peach Springs, Arizona, on the south rim of the Grand Canyon — cites critical water shortages on the Colorado River as the primary concern. The resolution also flags light pollution, wastewater discharge, and other environmental and community impacts. It calls on federal, state, and local governments to fulfill their government-to-government consultation obligations before approving any hyperscale data center project that could affect tribal resources. Two Navajo communities (Shiprock and Nageezi, NM) have adopted the same resolution; three Arizona Navajo communities (Lechee, Teec Nos Pos, Low Mountain) are committing to introduce it.

Arizona 3-year data center tax exemption pause
Arizona · Effective July 1, 2026 · Ariz. Laws 2026, Ch. 140 (HB 4168 / SB 1861, signed June 13, 2026, eff. July 1, 2026)
Arizona's 2026 budget law (HB 4168, Laws 2026 Ch. 140) pauses the state's data center sales and use tax exemption for three years. From July 1, 2026 through June 30, 2029, the Arizona Commerce Authority cannot accept any new applications for the exemption, and no new data center qualifies for this tax relief. Existing certifications that were already awarded remain valid — the law only blocks new ones. The pause is expected to save the state roughly $38 million per year. Governor Hobbs had initially asked to eliminate the tax exemption entirely; the three-year pause was the bipartisan compromise reached during budget negotiations.

Arizona Data Center Tax Incentive Moratorium (3-year, 2026)
Arizona · Effective July 1, 2026 · Arizona FY 2027 Budget Bill (signed June 13, 2026); three-year data center sales tax exemption moratorium
Arizona Governor Katie Hobbs signed the state's $18.3 billion FY 2027 budget on June 13, 2026, which included a bipartisan provision imposing a three-year pause on new sales tax exemptions for data centers (July 1, 2026 – June 30, 2029). Arizona's 2013 data-center sales-tax break costs the state roughly $38 million per year; existing exemptions remain in effect, but no new certificates can be issued until the moratorium lifts. The measure is projected to save $57 million over three fiscal years while policymakers study whether the incentives still serve the state's interests.

TVA data center capacity commitment charge (2026)
Tennessee Valley Authority · Effective October 1, 2026 · Tenn. Valley Auth. Bd. of Dirs. — Data Center Capacity Commitment Charge (approved Aug. 20, 2026; eff. Oct. 1, 2026)
The Tennessee Valley Authority's Board of Directors approved a separate, higher wholesale rate for data centers on August 20, 2026, effective October 1. New or expanding data center loads above 5 megawatts now fall under a Capacity Commitment Charge attached to TVA's data center rate schedules, designed to recover the incremental capacity costs those customers impose on the system. The headline figures are substantial: upfront capacity commitment charges of roughly $1.5 million per megawatt, payable over three to five years, and an all-in average billing increase for data center customers of about 10%, phased in across three consecutive fiscal years. The stated purpose is to keep residential rates low while still serving growing data center demand. TVA matters here out of proportion to a single utility. It is a federal corporate agency supplying power across seven states, so this is not a state rate case but a regional cost-allocation decision reaching a large share of the Southeast — and TVA is among the first large US utilities to adopt a tariff aimed specifically at AI-driven load. Where most 2026 measures in this dataset restrict where data centers may be built, this one changes what they pay to run.

Bartz v. Anthropic

In June 2025 Judge William Alsup ruled that training on lawfully purchased books was fair use. The piracy claims (LibGen ingestion) proceeded toward settlement; in September 2025 Anthropic agreed to a $1.5 billion class settlement covering ~500,000 works. Judge Alsup granted preliminary approval September 25, 2025 and final approval July 20, 2026. The appeal period runs through August 19, 2026; class members will not receive payments until at least end of 2026.

COPPA requires online services aimed at children under 13 to get verifiable parental consent before collecting kids' personal data. The 2025 rule update — fully in effect since April 22, 2026 — adds biometric identifiers (like face templates and voiceprints, which matter for AI tools), requires separate parental consent before sharing children's data for targeted advertising, and tightens data retention limits.
