Bill > HB0059

This bill modifies existing Wyoming law regarding limited mining operations, expanding water quality testing requirements for small-scale mining activities (defined as operations on 15 acres or less). Currently, operators must notify the land quality division before commencing operations, and this bill adds a requirement to also notify the water quality division. The key new provision allows the Department of Environmental Quality to require water quality testing before mining begins if there is a potential impact to domestic or drinking water sources. Under the new provision, the department can require operators to delay the start of their mining operations to complete necessary water quality testing. The bill also mandates that the environmental quality council develop rules to implement these new requirements, and the act will become effective immediately upon completing the standard legislative process. The aim appears to be protecting water resources by providing additional oversight and testing for small-scale mining operations that might affect local water supplies.
