Summary

This bill addresses zoning restrictions on small modular reactors in Arizona by preventing counties from using zoning ordinances to block their construction and operation when they are located alongside large industrial energy users that already have appropriate zoning approval. The bill requires that reactor operators provide public notice and hold at least one public comment session in the county before proceeding. Additionally, the bill directs the Arizona Corporation Commission to establish rules that define the key terms used in the legislation.
