Metallic Mineral Mining and Advanced Exploration

Contact: Mark Stebbins

In April 2012, the Maine Legislature enacted a law directing the Department of Environmental Protection to undertake a two-part rulemaking process to modernize the State’s regulatory process for metallic mineral mining.

In the first phase, the Department clarified the permit requirements for exploration and advanced exploration activities. Under our amended rules, exploration activities, which limit excavations to a maximum surface opening of no more than 300 square feet, do not require a permit, but must instead submit a work plan and meet a number of performance standards designed to protect natural resources and properly restore the exploration site. The advanced exploration requirements include a two tier permitting process that creates a graduated scale for classifying advanced exploration activities (minimal environmental impact versus a higher level of environmental impact). Advanced exploration activities fall within into two general categories: Tier One advanced exploration activities involve the excavation and removal of up to 2,000 tons of material, while Tier Two advanced exploration activities may involve up to 10,000 tons of excavated material.
