Bill narrows how Utah approves and challenges water rights. The state engineer may only consider protests tied to approval rules. Decisions focus on unclaimed water, no harm to existing rights, feasible plans, and welfare limited to water use, amount, quality, or availability. Broader social/environmental claims go to other agencies. Sets rules for temporary and fixed-time uses and saved water. Assumes harm if part of a right isn't used for 7 years. Only people with specific injury can sue.
