AIPG’s May 2017 Sand Mine Seminars and Field Trip
Christine Lilek CPG #10195 Wisconsin Section President and Conference Chairperson
The Wisconsin Department of Natural Resources (WDNR) estimates that there are more than 2,500 nonmetallic mines (NMM) in the state that mine sand, gravel, limestone, dolomite and igneous rock for aggregate, fill and landscaping; dimen- sion stone for monuments, landscaping and buildings; volcanic andesite for shingles; peat for horticulture and landscaping; industrial sand for a variety of uses; and other nonmetallic minerals.

In order to bring these mining professionals together, National AIPG and WI Section hosted the May 11 – 13, 2017, Sand Mine Life Cycle Seminar and Wisconsin Pollutant Discharge Elimination System (WPDES) Nonmetallic Mining Permit Process Seminar and Industrial Sand Resources of SW Wisconsin Field Trip in Eau Claire, Wisconsin with the cooperation of AIPG Minnesota Section, WDNR, Wisconsin Geologic Natural History Survey (Survey), and the Wisconsin Industrial Sand Association. The event gathered over 125 presenters, exhibitors, sponsors, professionals and students from many states across the nation and from Canada.
Presentations included all aspects of planning, siting, per- mitting, operating and reclaiming sand mines. Twenty profes- sionals and researchers gave oral presentations and twelve

The May 13 Field Trip showcased outcrops, mine sites, and drill cores of the major rock units in the industrial sand min- ing region of west-central Wisconsin. These units included the Cambrian Eau Claire shale (fill), Wonewoc sandstone (indus- trial sand), Tunnel City shale and sandstone (fill and poten- tially industrial sand), St. Lawrence Formation dolostone and siltstone (aggregate and fill), Jordan sandstone (industrial sand), and the Ordovician Prairie du Chien dolostone (aggre- gate). The trip proceeded stratigraphically up-section, showing the rock units from oldest to youngest, and highlighting the geologic history recorded in these rocks, their geochemistry and mineralogy, and their natural resource potential. We even got to drive through an operating sand mine! Copies of the presentations and field trip guide will be made available to AIPG members on the WI AIPG Section webpage in the near future.
