Welcome and Introductions a. Dave Malone, ISU and Committee Chairman i. Dave welcomed everyone to the meeting. Attendees introduced themselves and gave information about their affiliation and mapping interests. b. Dick Berg, ISGS i. Dick welcomed and thanked everyone for coming to the IGMAC meeting. He commented on the diversity and commitment of the group. c. William Shilts, PRI i. Bill talked about his history with bringing 3-D geological mapping to Illinois. He believes that it is important to put maps into the updated form and that 3-D mapping is of economic importance to the state. d. Dave Malone, ISU, commented on the Purpose of Committee: i. The committee has a practical purpose of providing feedback to the ISGS on its mapping program ii. To help the ISGS set long and short term mapping priorities, get funding, identify available resources, and to get the final products out to the consumer. The USGS looks at the makeup of the committee and attendees at the planning meeting when determining funding 2. Old Business, Dave Malone, Chair. a. Approval of Minutes from September 6, 2012 i. A motion was made to approve the 2012 IGMAC minutes; a change was made to the wording of a comment made by Paul Schuch during the discussion section on page 5. The change was recorded. A motion to accept the minutes as revised was made. The motion was seconded. Motion to approve the minutes as revised was passed. 3. New Business a. A motion was made to accept the three new members (1 new and 2 representatives were present). The motion was seconded and approved. b. Dave Malone displayed a map that with areas with completed mapping. 1082 quads have been mapped in Illinois. c. Long Range Planning Drew Phillips, ISGS

Page 2 of 5 i. Review of FY 2012 5 quadrangles and the Kane Co. compilation were delivered to USGS. 4 quadrangles and were published by the ISGS. ii. STATEMAP - $5.2 million were awarded to 42 Geological Surveys. $9.6 million was requested. The ISGS was the 3rd highest awardee with around $195,000, well below its request of $300,000. New Mexico and California had larger awards than Illinois. The more active the geological survey, the larger the award usually is. The ISGS program was reduced to 6 quadrangles and one compilation to fit within reduced award. iii. The STATEMAP review committee commented that the FY13 proposal was well written and well justified. iv. Great Lakes Geologic Mapping Coalition (GLGMC) - $750,000 was allocated to the eight state coalition. $96,344 was given to the ISGS to finish Lake and McHenry Co. and to begin work on Will Co. Will Co. was chosen because of increased interest in some of the surrounding counties including the Illiana Expressway and to develop new resources. v. Development of long term mapping priorities is by: 1. Institutional Review 2. Input from mappers and IGMAC 3. Strategic and collaborative opportunities vi. Extent of mapping in Illinois- a map was displayed showing areas in Illinois that have some sort of geologic map constructed between the years1942-2010. vii. A map of the areas for future mapping projects was displayed d. 2012 program comments and discussion i. Geographic 1. Illinois Valley 2. I-55 to I-57 connector in Will Co. 3. Galena 4. The Quad Cities ii. Targets 1. Shale gas- fracking, water use, contamination, seismicity 2. Fluorite resources 3. Hazards 4. Proactive outreach societal impact iii. 2-5 year plan 1. Bedrock Mapping: Illinois Valley work now extending to the south and southeast. Work in the northwest is dependent upon personnel. Targets include: a. Energy b. Hazards c. Geological History 2. Surficial Mapping: Will Co., finishing Lake Co. and McHenry Co., Mahomet Valley, Kaskaskia/lower Wabash, Whiteside Co. (Anderson compilation) completed. Targets include: a. Groundwater b. Hazards c. Seismicity d. Aggregate Resources e. Geological History iv. Discussion 1. Human resources are a determining factor in how different areas are chosen for inclusion in the proposal. Limits on personnel are due to available resources. The committee can help to find additional resources for mapping. There are currently more personnel working on ISGS

Page 3 of 5 projects than the USGS and GLGMC combined. Dick Berg commented if a market were created for mapping, universities would train people in mapping skills. 2. S. Gustison: Doesn t see too much activity in terms of energy. He wants to know what the plans are in this respect. Phillips responded that nothing is specifically planned at this point. Denny responded that 2 quads are being proposed that are directed at energy 3. Can GIS personnel add overlays of population and population growth? This could help with resources and resource management. 4. Northeast Illinois There is potential funding from the Chicago Metropolitan Agency for Planning (CMAP), Sea Grant, and Municipal Planning Council. Has anyone contacted them for funding? Berg responded that there has been contact with some of them. The ISGS has a new Outreach Coordinator who will be working on this. 5. A. Anders: NSF has $5 million to establish Critical Zone Observatory for water transport, nutrients, etc. There will be more surficial work geological that will be done. This may involve the UI, Purdue, Iowa and others. 6. The ISGS is part of the largest institution (Prairie Research Institute) on campus, which has liaisons with government, business, other academic institution as well as a strategic plan in place. The ISGS and PRI want to increase public awareness of the work done here and that it is a good quality resource that is available to them. The ISGS and PRI need to connect with all citizens of Illinois and particularly with those in the Chicago area. 7. Hydraulic fracturing The Illinois Department of Natural Resources is adding around 20 new positions to deal with the new legislation on hydraulic fracturing. Bob Bauer talked about the legislation and is on a task force dealing with hydraulic fracturing. A website is being created for the public. 8. Integrated resource management is being used in Kane Co. Maybe this is something that the ISGS/PRI should be looking into. Karen Wittier and Terry McLennand (PRI Executive staff) can help with contacts. e. FY 14 Program Proposal Presentations D. Malone referenced map highlighting the areas that are being considered for the 5-10 year plan. What maps do people want? What expertise is available? The areas under consideration are there because the ISGS perceives them as having issues important to the population of Illinois, including water resources, aggregate resources, and hazards. Areas with societal needs can be added or prioritized if there is funding for the creation of that map. i. Bedrock Mapping (Brett Denny) - The three new quadrangles, Hardin, Baldwin, and Thebes, and three that had been previously proposed but ultimately cut for budgetary constraints, Steeleville, Harco, and Galatia, were presented. 1. Hardin - Structural geology, economic resources, NewAlbany Shale (may be able to analyze the New Albany Shale). 2. Baldwin/Steeleville - Economic resources (coal, oil, and gas), shallow oil and gas stratigraphic traps and low sulfur coal. 3. Harco/Galatia 3D mapping, economic resources (coal, oil, and gas), coal mines, unmapped faults and igneous dikes. Delineation of above will help with future mining plans. 4. Thebes Structural geology with possible neotechtonics, bedrock broadly exposed.

Page 4 of 5 Discussion: Findings from ongoing projects were discussed. These included: oil and gas, rare earth elements, core from the Hicks Dome are being analyzed, 6 miles of seismic lines at Hicks Dome are being processed, stratigraphic research focused on the lower Chesterian, refinement of the Ordovician, structural features, Sparks Hill Diatreme (volcanic vent) north of Hicks Dome where apatite in contact with fluorite was found, a fascinating occurrence. Questions: Why is the Illinois Valley not being stressed? Personnel limitations. If the proposal has to be reduced due to funding limitations, the Steeleville and Baldwin would be cut, but only after discussions with geologists. There is already a USGS map of Thebes, but it is a hybrid outcrop map, not a true bedrock map. Where is the proposed PCB landfill going to be sited? Dave Grimley pointed it out on the map. Is Urbana quad being considered for future mapping? The quad does not lie over the Mahomet Aquifer and so is not as big a priority as others. How is information for maps obtained? Information is from different methods: historical, walking ravines, photos, notes, pictures, historic and new well data, etc. Does the energy industry have information or do they need more? Is surface information a good indicator of the bedrock? No, not in Illinois because of thick glacial sedimentary cover. ii. Surficial Geology (Dave Grimley) The Sag Bridge, Frankfort and Manhattan, and Keyesport/Pleasant Mound quadrangles were presented for consideration. Stolletown, Emma, and Kane Co. Compilation were completed in August 2013. 1. The Sag Bridge and Frankfort & Manhattan in the northeast are being proposed because they are in an area of high population growth, the proposed Illiana Expressway and potential future airport, they are adjacent to areas previously worked on. There are groundwater concerns (geometry of aquifers), resources (sand and gravel), wetlands and stream ecology. Research questions: Last glacial chronology, till characterizations, Chicago outlet history (sedimentation and dredging of canal). There are also bedrock issues that could be looked at, but focusing primarily on the surficial geology. 2. Keyesport and Pleasant Mound in the south are being proposed for sand and gravel resources, groundwater reserves, coal and oil at depth, seismic hazards. Research questions: deglacial history, esker fan systems, water resources (Kaskaskia), and seismic hazards (Wabash and New Madrid zones) iii. Discussion: Should this proposal be endorsed? The ISGS should be given some flexibility about what cuts are made if needed. A motion was made stating, IGMAC endorses the ISGS plans for surficial and bedrock mapping for FY14. The motion was seconded and approved 4. Break for lunch at 11:55 am. 5. Great Lakes Geological Mapping Coalition An overview of how the GLGMC works and is funded was presented. The GLGMC is comprised of eight states and the USGS. The ISGS competes with the other states for STATEMAP funds. a. Will Co. (Olivier Caron) work with constituent base to determine what is needed and then work up from there. A quarterly report on work being done is given to constituents. Current work includes review of bore hole date, drill new bore holes (3 sites done and 4 th started next week), develop relationship with forest preserves, update and revise older

Page 5 of 5 maps(winter). Future plans include drilling, revising and validating maps, creating cross sections, create new bedrock and isopach maps. Reasons for mapping this area are: Peotone airport site, Illiana Expressway, water resources, and general land use planning. b. Lake/McHenry Co. (Jason Thomason) i. Lake Co.- A high growth area. Under GLGMC and STATEMAP funding, complete quadrangle maps and a county compilation were constructed. There are 200 bore holes, 400 borehole geophysical logs, and 20+ miles of geophysical transects. Maps have helped municipalities decide whether or not to buy Lake Michigan water (not a lot of good aquifer material in the county). Current and future work will complete a 3D map, work on final deliverables, and make deliverables available in different formats. ii. McHenry Co. Coalition, County, and CMAP funding. 3D cross section network, 3D visualization, 3D modeling, and 3D map project using freeware people can create their own maps, cross sections, derivative maps. The GLGMC funding can pinpoint areas for work. c. Discussion: What areas are being looked at for future work? Will Co., maybe Kankakee Co., Kendall Co., and Cook Co. (in the city of Chicago). Is Kendall Co. going to be worked on in the future? The answer was yes and that there is a 3D map coming out for Kendall Co. d. A motion stating, IGMAC supports the long-term plans of the Great Lakes Geologic Mapping Coalition in McHenry, Lake, Dupage, Cook, and Will Counties, IL, was made. The motion was seconded and approved. 6. EDMAP- Needs ISGS support in order to be funded. There are typically 2-4 projects per year. Freeport East has been worked on by Illinois State University (ISU). McHenry Co. (Woodstock, IL) has been worked on in cooperation with the ISGS. Funding is around $15,000/quad. Most ISU projects are surficial. 7. LiDAR- Don Luman (ISGS). Each STATEMAP quadrangle done last year had a LiDAR aspect to it. LiDAR was available in the 1990 s and was first used in Illinois in 2002. Advances have been due to the laser that is used. US Interagency Elevation Inventory is a cooperative project between NOAA and the US EPA with contributions from FEMA. Approximately 70 counties in Illinois have been covered by LiDAR. There are 65 counties have online data that is available for download. 8. Final Discussion -Citizens in Jo Daviess Co. are interested in water use and resources. Mapping focused on hydrogeology is being done in this county. 9. Adjournment-at 3:13 pm Respectfully submitted, Kathleen M. Henry Approved unanimously without amendment, 9/11/2014, RCB
