HB 2795 Arizona House · 57th Legislature - Second Regular Session

small modular reactors; zoning; approval

HB 2795 modifies Arizona law to allow small modular reactor (SMR) construction and operation by preventing local governments from restricting these projects under specific conditions. It requires SMR developers to obtain federal early site permits and design certifications, then submit proof of these to the county board of supervisors before local zoning rules can be overridden. This directly affects SMR developers and Arizona counties, ensuring federal approvals supersede local zoning for eligible projects. The law does not alter federal requirements but clarifies that counties cannot block SMR sites once the federal steps are completed and documented.

What changed between versions

Introduced Version House Engrossed Version (02/26/2026) · 3 edits · Feb 26, 2026
MINOR
The bill was reorganized and formatted for the House Engrossed version, but the substantive policy content regarding small modular reactors and aggregate mining zoning remains identical to the introduced version. The text was cleaned up to fix grammatical errors (such as 'shall MAY NOT') and standardize capitalization, ensuring the final enacted law is clear and legally sound without altering the original intent or rules.
TECHNICAL

Corrected grammatical errors and inconsistent capitalization throughout the text, such as changing 'shall MAY NOT' to 'shall may not' and standardizing the capitalization of terms like 'federal agency'.

Reformatted the document structure, including header information and page breaks, to align with the official House Engrossed format while preserving all original legislative text.

Expanded the list of allowable regulations for aggregate mining operations to explicitly include dust control, height regulations, setbacks, noise, and air pollution control, which were previously omitted from the detailed list in the introduced version.
