Gernatt requested that McMahon & Mann prepare permitting documents for the expansion of their facility, broadening the footprint of the mine area and extending processing operations to the west side of Great Valley Creek.

We made test borings, performed calculations pertaining to runoff, storm water storage capacities, culvert sizing and slope stability analyses. Site layout and grading plans were provided to maximize material yield and minimize material movement.

McMahon & Mann assisted Gernatt through the permitting process with the New York State Department of Environmental Conservation and the US Army Corps of Engineers.
