Maine: Natural Resources
The Department of Environmental Protection adopted amendments to regulations governing metallic mineral exploration and advanced exploration and mining. The amendments create a process for exclusion from Chapter 200 requirements (i.e., physical extraction, crushing, grinding, sorting, and storage of metallic minerals), and require ongoing water quality monitoring in cases where an exclusion is granted.
