Mining operations-blasting requirements.

Wyoming's HB 33 requires mining operators using explosives in noncoal surface mining operations to create detailed blasting plans and maintain public records. It mandates that operators log blast locations, explosive amounts, drill patterns, and safety measures for three years, and comply with fire code standards for explosive use. This applies directly to all operators conducting blasting in surface mining (including small-scale operations under 15 acres), requiring them to submit annual reports if explosives are used. The law also specifies that blasting must be performed by trained personnel and designed to prevent injury, property damage, or water resource impacts.
