The Association of Environmental & Engineering Geologists (AEG) Texas Chapter will run a tour of the San Miguel lignite mine in Christine, Texas. This South Texas mine is currently in operation under the North American Construction Group. The morning will cover talks about the history of the mine itself, the geology and site planning of the area, and the environmental permitting and reclamation process through the future. After lunch, we'll be taking a tour of the active mine site for an up close look! PPE: safety glasses, hardhats, closed toe or steel toe boots, high visibility vest. Cost includes transportation (bus), lunch, snacks, and water.
This field trip starts and ends at the convention center in San Antonio, Texas. The first part of the morning and lunch will be at the mine office. We will have an afternoon tour of the mine with minimal to moderate walking at stops inside the facility, on mostly level ground. While the trip is mostly in office or on the bus, please wear clothing you don’t mind getting dirty, as the mine floor may be muddy. A bathroom will be available at the mine office and on the bus.
