SD HB1287

Mining operations using explosives to extract sand, gravel, construction rock, pegmatite minerals, limestone, or cement-making materials must obtain permits under the more stringent chapter 45-6B, rather than the standard $100 annual license under chapter 45-6

Operators currently using explosives must report their explosives use to the department within 90 days of the Act's effective date, including use by contractors or subcontractors

New or expanding mining operations using explosives must obtain a chapter 45-6B permit by July 1, 2026, with a six-month extension available for good cause

Existing operators with chapter 45-6 permits must transition to chapter 45-6B permits on a schedule allowing 20% of operators to transition in each of five consecutive years starting July 1, 2026

The definition of "mining operation" is expanded to include extraction of any material by use of explosives, subjecting such operations to additional regulatory requirements including reclamation obligations
