Martin Marietta is seeking expansion of its quarry in Granite Falls, Minn., with plans to expand the operation to the west side of its property. Preliminary evaluations show the need to consider a wetland that was not designated during its earlier 1992 permit review, the Independent reports.
Jolene Johnson, from the Yellow Medicine County planning and zoning office told county commissioners she anticipates a much more extensive permitting process than a typical zoning decision, the news outlet says. She explained that her office will work with Martin Marietta officials and the DNR to complete an environmental assessment worksheet (EAW) which will, in turn, determine if an environmental impact study (EIS) is needed.
According to the Independent, Johnson told commissioners that the wetland at the quarry has already been impacted by man-made activities in the past. “It’s already been altered, she said. “That’s part of what has to be considered. There will be information and public comments as part of the EAW, and that will help to determine whether or not there’s a need for an EIS.”
If an EIS is needed, Johnson said it could delay plan for expansion.
