Bay City Sand Mine Development

« Return to Project Search

The Bay City Sand Mine is an underground sand mine for coarse round silica sand (Jordan Formation) used in the oil and gas industry. Ayres Associates was retained to complete a topographic survey of the extent of the existing mine tunnels for use in determining reserve calculations as well as potential venting locations.

Under previous employment, project manager Michael Stoffel was responsible for project management and permitting of the mine. Services included site design within a very tight site to be able to provide access to the Wild and Scenic STH 35, access to the sand formation, and turning movements for trucks hauling sand out of the mine. Permitting coordination involved the County Land and Zoning Department; the Wisconsin Department of Natural Resources for stormwater, air quality, and bat sanctuary protection; and the Wisconsin Department of Transportation for highway access and mineral rights. Tunnel plans call for following the sand formation under STH 35 to access deposits on the other side, where access is not possible.

The processed sand is shipped via rail to oil and natural gas wells for use as frac sand. The project included preparing a groundwater monitoring plan, a stormwater pollution prevention plan, and underground surveying to document the location of the tunnels.
