2 Page 2 of 8 b. Long Range Planning, Drew Phillips, ISGS (PowerPoint presentation): i. Intro to National Geologic Mapping Act ii. Mapping programs in Illinois iii. Role of IGMAC iv. Defining mapping plans 1. Long Range (5 to 10 years) a. Criteria scientific questions, societal needs, committee input b. Nine priority mapping areas Chicago, Northwest, Sandwich Fault Zone, Quad Cities, Mahomet Valley, Illinois Valley, Kaskaskia Valley, Wabash Valley, Southern Illinois c. Recent IGMAC input to long range plan 2. Short Range (2 to 5 years) a. Criteria achieve long range goals, select by judgement (resources, staff availability, mapping inertia, etc.). b. Same nine mapping areas involved as long range plan. 3. Proposed (next year) a. Criteria achieve short range goals, select by judgement b. $300K STATEMAP RFP full amount never available but always applied for. USGS can show demand for mapping and ISGS can show capacity to fulfill the contract. v. STATEMAP award for FY $10.4 million requested by 43 state geological surveys. 2. $5.6 million was awarded (53% awarded on average). 3. $159K awarded to the ISGS. The ISGS reduced the proposed quadrangles to seven to accommodate the reduced award. vi. New challenge - to work on ways to display map progress in new ways with new attributes (i.e. surficial vs bedrock). vii. FY 2017 Deliverables - Delivered six quadrangles to the USGS: Baldwin, Chana, DeSoto, Monticello, Pleasant Mound, and Tinley Park. All maps will be available online on ISGS website in October. viii. Discussion: 1. Devera (ISGS): suggests extending current priority area around Rockford over into JoDaviess County to catch the driftless area and the Plum River Fault. 2. Malone (ISU): Would like to propose quadrangles for EDMAP in LaSalle County. Need committee to consider the effect the status map has on EDMAP project justification. Higher likelihood of funding if the proposed EDMAP quadrangles are part of short range plan and near current STATEMAP quadrangles. Would like

3 Page 3 of 8 a couple of quadrangles in LaSalle to be added to short range plan on the status map. a. Berg (ISGS): suggests adjusting map to help EDMAP b. Devera (ISGS): points out there is economic interest in the St. Peters Sandstone in the LaSalle County area c. Brown (ISGS): ISGS resource planning and business strategy may not allow for adjusting short range plan status map to accommodate current EDMAP request 3. Curtis (IDOT): How many STATEMAP maps are typically completed each year? a. Phillips (ISGS): Six with current funding. 4. Curtis (IDOT): attempt to clarify long range vs short range planning. Asks, if long range tied to overall goals of the State and that the short range goals are tied to seeking money from STATEMAP? a. Audience in general concurs. 5. Berg (ISGS): suggests changing long term goals from 5-10 year, to 5-20 years, since the status map shows more maps in the long range plan than could possibly be mapped in 10 years. Or, perhaps leave specific years off and use alternative wording. 6. McGuire (UIUC): Suggests adding specific criteria for justification of each map. a. Phillips (ISGS) and others: the specific criteria and justification are provided for the proposed STATEMAP quadrangles in upcoming presentations at the meeting and provided to the USGS in the proposal. 7. Curtis (IDOT): suggests listing criteria and justification to nine priority mapping areas. 8. Anders (UIUC): points out nine priority areas and only six maps funded each year. Perhaps IGMAC committee should rank the mapping areas. If Critical Zone Observatory (CZO) had a favorite priority area it would be the Mahomet Valley. 9. Berg (ISGS): agrees with expanding some mapping areas on the status map Rockford out to JoDaviess County; and Kaskaskia Valley down into the St. Louis area. 10. Malone (ISU): Does ISGS map any quadrangles without STATEMAP funding? a. Phillips (ISGS): No, not currently. 11. Curtis (IDOT): EDMAP is a separate proposal from STATEMAP a. Malone (ISU): need coordination between proposals to give EDMAP better chance at funding.

4 Page 4 of 8 b. Phillips (ISGS): EDMAP has lower level of funding and is mapped by students. 12. McGuire (UIUC): suggests criteria for ranking mapping areas; one criteria could be how mapping can inform and aid urban planners a. Phillips (ISGS): in future could list top three justifications next to each listed priority mapping area b. Brown (ISGS): don t add these justifications to the proposal but present to committee at meeting c. FY 2017 results and FY 2019 STATEMAP proposal presentations i. Surficial Mapping, Dave Grimley, ISGS (PowerPoint presentation): 1. FY 2017 results: Northeast Illinois Tinley Park & Monticello; Southern Illinois Pleasant Mound a. Tinley Park Wadsworth Formation till, glacial Lake Tinley, CME 75 drilling b. Monticello more detailed Mahomet Aquifer data, gamma logs, electrical resistivity survey, magnetic susceptibility c. Pleasant Mound glacial lineations, electrical resistivity surveys, new cone-penetration testing and hydraulic profiling tools used, compositional data 2. FY 2018 current projects: Northeast Illinois Palos Park; Southern Illinois Beaver Creek & Lawrenceville 3. FY 2019 maps being proposed: Northern Illinois Blue Island, Harvey, Steger (north half); Southern Illinois Crossville, New Harmony (partial) Quadrangles; Williamson County surficial and bedrock compilations a. Blue Island, Harvey and Steger mapping in densely populated areas Chicago Urban Area, flood prone area in glacial Lake Chicago, adds to the history of the Chicago outlet, mapped by Bretz but no 3D component, better understanding moraine systems, sand and gravel resources, dolomite resources, aquifer resources b. Crossville and New Harmony earthquake hazards, groundwater resources, aggregate resources, paleoseismic features (liquefaction observations), aggregate resources, subglacial lineation research, slackwater lake deposits, confluence of major rivers, connects gap in prior mapping c. Williamson County merge GIS files, add cross sections, data point locations, adjust contacts according to LiDAR elevation data 4. Discussion:

Elrick (ISGS): Focus is to compile data b. Berg (ISGS): add infrastructure development to the proposal c. Malone (ISU): More bedrock exposures in Quad Cities area, why map Stewart? i. Devera (ISGS): If funding is cut Stewart would be most likely be cut. d. Malone (ISU): Radium issue in LaSalle County should become a priority. d. Final Discussion and Committee statements i. Discussion 1. Kerasotes (Covia Corp.): Would like Wedron Quadrangle moved to short range plan. Economic concerns and need for detailed bedrock topography in area. 2. McGuire (UIUC): reaffirms that Blue Island, Harvey and Steger are good choices for the proposal, fits into other environmental concerns in the area ii. Approval of FY 2019 mapping proposal: 1.

Eric Peterson (ISU) and Dave Malone (ISU) will be applying for the next round of EDMAP funding. No quadrangles were identified at the meeting. 4. Topical Presentations a. Critical Minerals of Illinois, Scott Elrick, ISGS (PowerPoint presentation) i. 3DEEP now to be known as Critical Minerals Mapping Initiative ii. USGS stated that the Illinois critical minerals pre-assessment map was exemplary and worthy of a template for other states to follow and asked ISGS to write up the methodology iii. Methodology was shown in presentation iv. Illinois has 3 priority areas: IL-KY Fluorspar District, Upper MVT District, and Mississippi Valley b. Data & Information for The Boring Company Chicago Project, Bob Bauer, ISGS (PowerPoint presentation) i. Bauer highlighted the many challenges to create a tunnel 50 feet below the surface, without drilling into bedrock, in a densely populated area with a lot of subsurface infrastructure already in place. c. Fault revealed by lidar in Chana Quadrangle, Franck Delpomdor, ISGS (PowerPoint presentation) i. Delpomdor displayed where lidar revealed a linear feature on the surface materials of the quadrangle he mapped. ii. He explained that, after consulting with other geologists familiar with the study area, he currently has the lineation s mapped as a secondary fault
