HF4764

Purpose

• The bill changes Minnesota’s wetland replacement rules to guide where and how wetlands that are impacted must be replaced. It updates the process for siting replacements, strengthens the role of wetland banking, and sets criteria to determine what counts as a reasonable and environmentally beneficial replacement.

Main Provisions (What the bill changes or adds)

• Siting priority for wetland replacements
  • Replacements should be located, in order of priority, at: 1) the same minor watershed as the impacted wetland, 2) the same watershed as the impacted wetland, 3) the same wetland bank service area as the impacted wetland, 4) another wetland bank service area.
• Special exception for older banking credits
  • Wetland banking credits approved from a complete banking application submitted by April 1, 1996 can be used to replace wetland impacts from public transportation projects anywhere in the state.
• Banking priority for siting
  • For banking, the priority order starts with the third option (same bank service area) rather than the first two options, following rules adopted under the relevant statute.
• Flexibility when higher-priority opportunities aren’t available
  • If opportunities at the higher-priority levels are not reasonably practicable or environmentally beneficial, applicants may seek replacement opportunities at the next level.
• Definition of what counts as a good replacement opportunity
  • “Reasonable practicable and environmentally beneficial” opportunities are defined as:
  • using naturally occurring hydrogeomorphological conditions and requiring minimal landscape alteration,
  • having a high likelihood of becoming a functional wetland that lasts in perpetuity,
  • not adversely affecting other important habitats or ecological communities,
  • being available and feasible given cost, existing technology, and logistics, aligned with project goals.
• Collaboration and governance
  • Regulatory agencies, local governments, and other entities must work together to identify potential replacement opportunities within their jurisdictions.
  • The board must establish wetland replacement ratios and bank service area priorities to guide siting and encourage use of high-priority areas.
• Environmental impact statement (EIS) process and timing
  • Wetland replacement sites identified under the priority order can be approved as part of a replacement plan under specified statutes without needing further changes to fit the priority order, even if new mitigation sites or credits become available after an EIS is completed.
  • Replacement plan applications must be submitted within one year after the adequacy determination of the EIS to be eligible for approval under this provision.

Significant changes to existing law

• Reframes the priority for siting wetland replacements to emphasize proximity within bank service areas, potentially prioritizing local replacement options over distant ones.
• Expands the use of older wetland banking credits for statewide public transportation projects.
• Introduces a formal, multi-step process for evaluating “reasonable practicable and environmentally beneficial” replacement opportunities with clearer criteria.
• Requires ongoing collaboration among agencies and local units to identify and develop replacement opportunities.
• Establishes specific timelines and conditions under which replacement plans tied to an EIS can be approved, integrating siting priorities into the EIS process.
