Allow water right holders to consent to waive adverse effects analysis in permit or change applications
SB 190 amends Montana water law to let a water right holder file a written consent to approval of a permit, change, or temporary change application, and thereby waive the Department of Natural Resources and Conservation’s adverse effects analysis for that specific water right. The bill makes this consent-based exception in several parts of the water-right permitting and change statutes, including new permits, changes in appropriation rights, temporary changes, groundwater applications in closed basins, and certain instream flow applications. In practical terms, if a right holder consents in writing, the applicant no longer has to prove that the application will not adversely affect that particular right.
The bill also updates related procedures for water-right permits and changes, including existing standards for legal availability, adverse effect objections, large-volume appropriations, out-of-state use, replacement wells, replacement points of diversion, and temporary instream-flow changes. It preserves other core requirements such as beneficial use, possessory interest or landowner consent, water quality protections, and special federal authorization on national forest system lands. The bill does not eliminate adverse effects review generally; it creates a targeted waiver where the affected right holder affirmatively consents.
The impact on state law is to streamline some water-right permitting and change applications by reducing the need for agency analysis and potential objections when all affected rights holders agree. It likely shortens review time and lowers administrative burden for applicants and the department in those cases, while leaving the broader prior-appropriation framework intact. The bill also reinforces that written consented rights are excluded from adverse-effects determinations in several sections of the Montana Code Annotated.
Overall sentiment around the bill appears strongly favorable. It passed the Senate and House with large margins, including unanimous or near-unanimous votes on several readings, and only a small number of dissenting votes on the House floor. The committee vote in the Senate Natural Resources Committee was also favorable, with one dissenting vote. That voting pattern suggests broad bipartisan support for the bill’s consent-based approach to water-right administration.
The main point of contention is the policy tradeoff between administrative efficiency and protection of existing water rights. Supporters appear to view written consent as a sufficient safeguard because the affected right holder is voluntarily agreeing to the waiver. Any concern would likely come from those worried that reducing adverse-effects review could weaken oversight, complicate enforcement, or create pressure on smaller or downstream water users, but the recorded votes indicate that such concerns did not generate significant opposition in the Legislature.
SB 190 amends multiple sections of Montana’s water code to provide that the Department of Natural Resources and Conservation may not conduct an adverse effects analysis for a water right if the holder files a written consent to approval of the application. This affects permit applications, changes in appropriation rights, temporary changes, groundwater permits in closed basins, and instream-flow-related changes. The bill leaves intact the rest of the permitting and change criteria, including beneficial use, legal availability, water quality, and special-use requirements on national forest lands, but it creates a new statutory carveout for consented rights.
The bill’s reception was broadly positive and low-conflict. It advanced through the Senate and House with strong vote totals, including unanimous passage on second and third readings in the Senate and overwhelming concurrence in the House. The committee vote in Senate Natural Resources was also favorable, indicating that lawmakers generally supported the bill’s attempt to simplify water-right processing when affected parties agree.
The principal issue is whether a written consent should fully replace the department’s adverse-effects review for the consenting right. Supporters likely see consent as a clear, voluntary waiver that reduces delay and paperwork, while preserving protections for nonconsenting rights. Potential critics may worry that the change could reduce agency oversight or create downstream effects if consent is not fully informed or if broader basin impacts are not captured by the waiver. The recorded votes show only limited opposition, suggesting these concerns were present but not politically decisive.
