Excavations for Borrow, Clay, Topsoil or Silt

Statutory Reference: Article 7: PERFORMANCE STANDARDS FOR EXCAVATIONS FOR BORROW, CLAY, TOPSOIL OR SILT
38 §488-24. Nonmetallic mining accessory uses and facilities. Accessory uses and facilities within an excavation or quarry operating under the performance standards in article 7 or 8-A are exempt from this article if the performance standards in article 7 or 8-A or the rules implementing those articles are at a minimum as restrictive as the standards imposed under this article. For the purposes of this subsection, "accessory uses and facilities" means uses and facilities associated with the processing of material pursuant to article 7 or 8-A such as screening and the crushing, loading and manufacture of ready-mix concrete and bituminous concrete and associated products and weight scales, scale shacks and maintenance garages. This subsection does not apply to a development constructed during or after reclamation.

Metallic Mineral Mining and Advanced Exploration

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.
