MN SF2741

Requires a minimum three-strand wire fence along the perimeter of mines where operations have ceased for six consecutive months or longer, with county mine inspectors able to require more secure fencing based on local site conditions.

Establishes that if a mine is abandoned and the original operator no longer exists, the fee owner must erect and maintain required fencing, barriers, or signs, or the county may abate the nuisance and assess costs under section 429.101.

Exempts certain excavations and pits from fencing requirements if located on property owned by the Iron Range Resources and Rehabilitation office, used for grants-in-aid trails, municipal parks, recreational areas, or economic development purposes.

Allows county mine inspectors to grant exemptions for abandoned excavations with existing fencing reasonably similar to standards or that do not constitute a safety hazard, provided recipients post appropriate warning signs at public access points.

Makes theft of mining safety fences, guards, barriers, signs, or rails subject to penalties under section 609.52, and establishes misdemeanor penalties for workers who remove or fail to replace required safety structures.
