Metallic Mineral Mining and Advanced Exploration

Contact: Mark Stebbins (822-6367)

In April 2102, 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 revised 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 1,000 tons of material, while Tier Two advanced exploration activities may involve up to 5,000 tons of excavated material. The routine technical rules for exploration and advanced exploration adopted in March 2013 by the Department still remain in effect and can be found in Subchapter 3 of the Department's Chapter 200 Exploration, Advanced Exploration and Mining rules.

The second part of the rulemaking process directed the Department to provisionally adopt and submit to the Legislature for review rules that update Maine's mining regulations to provide a comprehensive application and permitting process for several types of activities related to mining. Mining activities involve the excavation of 5,000 tons or more of material and are subject to a wide ranging suite of requirements. Although the Board of Environmental Protection provisionally adopted these rules on January 10, 2014, they were not approved by the Legislature.

Permit application for metallic mineral mining will be processed in accordance with Maine Metallic Mineral Mining Act and the Department's existing Chapter 200 rules. In the event of conflicting statutory and rule requirements, the statute will control.
