Republican caucus voices local-control concerns over bill limiting county authority for small modular reactors

Adam Webb, a staff presenter, summarized Senate Bill 14-18 as written: “Senate Bill 14-18 prohibits certain counties from regulating the user occupation of land for the construction operation of small modular nuclear reactors or SMRs,” and outlined provisions that let a utility replace an existing thermal electric generating unit with an SMR without seeking a new certificate of environmental compatibility in specified circumstances.

Representative Blackman expressed strong objections during caucus debate, saying, “I I have a problem with that, because we are I mean, as Republicans, we are supposed to be for local control,” and warning, “if that is what this does, what I'm reading, I'll have to be a no on the floor on something like this.” His remarks framed the concern as a conflict between the bill’s state preemption and members’ local-control principles.

Staff (Adam Webb) answered that the bill’s preemption applies only to counties that meet a population requirement and explained the population threshold in the bill language, saying it applies to counties “if they meet the requirement … it's 500,000 persons or less.” He also summarized implementation tasks the bill assigns to the Arizona Corporation Commission in its implementation provisions.

Why it matters: The bill would constrain some counties’ authority over land use for nuclear technology siting and shift certain regulatory determinations to state-level processes, raising policy and political questions about local governance, permitting, and the role of the Corporation Commission.

What’s next: Staff said SB 14-18 is on the third-week consent calendar and presenters remained available for questions. No formal action or vote occurred during the caucus; further committee floor consideration was expected as the bill proceeds.
