Part 8420.0935 - STANDARDS AND CRITERIA FOR IDENTIFICATION, PROTECTION, AND MANAGEMENT OF CALCAREOUS FENS
Current through Register Vol. 49, No. 13, September 23, 2024
Subpart 1. Purpose.
The purpose of this part is to provide minimum standards and criteria for identifying, protecting, and managing calcareous fens as authorized by Minnesota Statutes, section 103G.223. Calcareous fens, as identified by the commissioner, must not be impacted or otherwise altered or degraded, wholly or partially, by any action, unless the commissioner, under an approved management plan, decides some alteration is necessary. The exemptions under part 8420.0420 and the sequencing provisions under part 8420.0520 do not apply to calcareous fens.
Subp. 2. Identifying calcareous fens.
A calcareous fen is a peat-accumulating wetland dominated by distinct groundwater inflows having specific chemical characteristics. The water is characterized as circumneutral to alkaline, with high concentrations of calcium and low dissolved oxygen content. The chemistry provides an environment for specific and often rare hydrophytic plants.
Subp. 3. Procedures to list calcareous fens.
Subp. 4. Management plans.
Calcareous fens must not be impacted or otherwise altered or degraded except as provided for in a management plan approved by the commissioner. The commissioner must provide technical assistance to landowners or project sponsors in the development of management plans.
Subp. 5. Restoration.
The commissioner may approve management plans to restore or upgrade a previously damaged calcareous fen.
Subp. 6. Appeals.
Subp. 7. Enforcement procedures.
Enforcement procedures for calcareous fens must be conducted consistent with Minnesota Statutes, sections 103G.141 and 103G.2372, except that necessary restoration or replacement activities, if required, must be determined by the commissioner, in consultation with the local soil and water conservation district.
