SF4911

Purpose

• This bill amends Minnesota law to change how wetlands that are impacted by projects must be replaced. It updates where and how new wetlands should be created or restored, and how wetlands can be replaced using various mechanisms, including wetland banking credits.

Main Provisions

• Siting order for wetland replacement: when replacing an impacted wetland, replacement must follow this priority order: 1) in the same minor watershed as the impacted wetland, 2) in the same watershed as the impacted wetland, 3) in the same wetland bank service area as the impacted wetland, 4) in any other wetland bank service area.
• Special allowance for legacy credits: wetland banking credits approved from a complete wetland banking application submitted by April 1, 1996 may be used to replace wetland impacts from public transportation projects anywhere in the state.
• Priority order shift for banking: the priority order for replacement by wetland banking begins at the bank service area level (clause 3) under rules adopted for section 103G.2242, instead of the earlier focus on the minor watershed or watershed.
• Flexible replacement opportunities: if reasonable practicable and environmentally beneficial replacement opportunities aren’t available at the top priorites, the applicant may pursue opportunities at the next level of the priority sequence.
• Definition of “reasonable practicable and environmentally beneficial”: replacements should (1) leverage natural hydrogeomorphological conditions with minimal landscape changes, (2) have a high chance of becoming a functioning wetland that lasts indefinitely, (3) not harm other important habitats or ecological communities, and (4) be feasible given cost, technology, and logistical considerations and the project purpose.
• Collaboration requirement: regulatory agencies, local government units, and other entities involved in wetland restoration must work together to identify potential replacement opportunities within their areas.
• Board role on replacement rules: the board must establish wetland replacement ratios and bank service area priorities to guide siting and encourage use of high-priority areas.
• Conditional approval pathway tied to environmental review: wetlands identified under the priority system can be approved for a replacement plan under specified sections (e.g., 93.481, 103G.2242, 103G.2243) without further modification for priority order, even if new mitigation sites or credits are not available after an adequate environmental impact statement.
• Timely application requirement: replacement plan applications must be submitted within one year after the adequacy determination of the environmental impact statement (EIS) to be eligible for approval under this pathway.

Notable Changes to Existing Law

• Revisions to the wetland replacement siting rules (Minnesota Statutes 2024, §103G.222, Subd. 3) to emphasize a bank-service-area-based priority and to incorporate a structured, four-level siting order.
• Explicit permission to use legacy wetland banking credits (submitted by April 1, 1996) for statewide public transportation projects.
• Formal guidance for defining what counts as reasonable practicable and environmentally beneficial replacement opportunities.
• Requirement for interagency collaboration and for the board to set replacement ratios and bank service area priorities.

Implementation & Oversight

• Responsibilities placed on the board to set replacement ratios and priorities for bank service areas.
• Regulatory agencies, local government units, and other wetland restoration entities must collaborate to identify replacement opportunities.
• Replacement plan approvals tied to adequate environmental review, with a defined one-year submission window after EIS adequacy determination.

Potential Impacts

• Stronger emphasis on wetland replacement within bank service areas and specific watersheds, potentially reducing replacement in distant locations.
• Use of older wetland credits may streamline funding for certain public transportation projects.
• Adds a structured framework for evaluating replacement opportunities and ensures interagency coordination.
