The eastern margin is that part of the folded Appalachians along the Virginia-West Virginia state lin e, extending northward to Cumberland, Maryland; the western margin is along the Cincinnati arch, paralleling the Indiana-Ohio state line and continuing southward into north-central Kentucky. These two marginal areas include major outcrops of Silurian rocks on opposite sides of the Appalachian basin. The northern boundary extends from Indiana across central Ohio to Pennsylvania; and the southern boundary extends from Madison County, Kentucky, to Alleghany County, Virginia. The northern boundary was selected in order to tie in with the recent Silurian study of Ulteig (1963) in northern Ohio; the southern, to include type localities for some of the Silurian formations discussed in the report. Purpose of Investigation This investigation of the Silurian strata of southern Ohio and parts of adjacent states was undertaken with the purpose of extending into the subsurface the field information obtained by previous workers. The work of Orton (1871) is noteworthy

February 1, 2018 Fair Shake Environmental Legal Services 159 South Main Street, Suite 1030 Akron, Ohio 44308 RE: Technical Report Review: "Evaluation of Groundwater Impacts, Dewatering of Proposed Enon Quarry, Clark County, Ohio " Dear Mr. Y skamp, I, Brent E. Huntsman, CPG, President and Principal Hydrogeologist ofTerran Corporation (Terran) was retained by Fair Shake Environmental Legal Services to review and comment upon the hydrogeologic characterization and predicted dewatering effects to the water resources of Mad River Township, Clark County, OH as described in a groundwater model report prepared for a mining permit modification. This report review was to include an evaluation of the aquifer response and hydraulic performance predicted by the model simulations of the groundwater system; the magnitude and extent of a cone of depression resulting from dewatering various limestone quarry pits. The purpose of my review is to provide a letter report summarizing my expert opinions regarding the adequacy of the groundwater model to appropriately simulate dewatering effects upon the local groundwater regime. All opinions in this report are based upon my review of existing information (developed through the litigation process in this case or in the public record) together with my 43-years of experience in applied hydrogeology, specifically aquifer characterization and water resources development. My current curriculum vita is included with this letter report as Attachment 2. These opinions are expressed to a reasonable degree of scientific and professional certainty. I reserve the right to supplement this report and opinions as additional material becomes available through the litigation process or continued review of public literature.

W estern Michigan University, 1990 West Branch field is a low-relief, NW-SE-trending anticline near the center of the Michigan basin. Since 1934, the Dundee Limestone (Middle Devonian) has produced over 12 million barrels of oil from this field. From core studies, six depositional facies types were recognized in the Dundee. These are dominated by bioclastic carbonate sand facies deposited in normal- marine shelf settings. Although burial cements have occluded some porosity, carbonate sand facies have retained significant primary interparticle porosity and are the most important reservoir rocks.

  • Development of Drinking Water and Ecological Unusually Sensitive Areas (Usas): Examples Using the Water and Biological Resources of Ohio
    Development of Drinking Water and Ecological Unusually Sensitive Areas (USAs): Examples Using the Water and Biological Resources of Ohio Colin Plank, Scott Zengel, Heidi Hinkeldey, Elaine Inouye, William Holton, Jeffery Dahlin, and Jacqueline Michel Research Planning, Inc., 1121 Park Street, Columbia, SC 29201, [email protected], 803-256-7322 (voice); 803-254-6445 (fax); and Christina Sames and Samuel Hall, Office of Pipeline Safety, Research and Special Programs Administration, U.S. Department of Transportation, Washington, D.C. 1.0 INTRODUCTION The U.S. Department of Transportation’s Research and Special Programs Administration (RSPA) is required to identify areas unusually sensitive to environmental damage in the event of a hazardous liquid pipeline accident. Pipeline operators that can affect "unusually sensitive areas" (USAs) must develop and follow an integrity management program to assess and evaluate the integrity of their pipelines. After extensive consultation with experts, government agencies, and other stakeholders, a process was developed to identify USAs for drinking water and ecological resources. In general the USA identification process involves selecting a subset of USA candidates from the larger group of Environmentally Sensitive Areas (ESAs), and then applying various filter criteria to the candidates to determine final USAs. For drinking water USAs this means identifying potentially sensitive public water systems (PWS), specifically surface water intakes and ground water wells, and subjecting them to filter

    information t o u s e r s This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target” for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again - beginning below the first row and continuing on until complete. 4. The majority of usefs indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation.

  • Geology of Michigan and the Great Lakes
    35133_Geo_Michigan_Cover.qxd 11/13/07 10:26 AM Page 1 “The Geology of Michigan and the Great Lakes” is written to augment any introductory earth science, environmental geology, geologic, or geographic course offering, and is designed to introduce students in Michigan and the Great Lakes to important regional geologic concepts and events. Although Michigan’s geologic past spans the Precambrian through the Holocene, much of the rock record, Pennsylvanian through Pliocene, is miss- ing. Glacial events during the Pleistocene removed these rocks. However, these same glacial events left behind a rich legacy of surficial deposits, various landscape features, lakes, and rivers. Michigan is one of the most scenic states in the nation, providing numerous recre- ational opportunities to inhabitants and visitors alike. Geology of the region has also played an important, and often controlling, role in the pattern of settlement and ongoing economic development of the state. Vital resources such as iron ore, copper, gypsum, salt, oil, and gas have greatly contributed to Michigan’s growth and industrial might. Ample supplies of high-quality water support a vibrant population and strong industrial base throughout the Great Lakes region. These water supplies are now becoming increasingly important in light of modern economic growth and population demands. This text introduces the student to the geology of Michigan and the Great Lakes region. It begins with the Precambrian basement terrains as they relate to plate tectonic events. It describes Paleozoic clastic and carbonate rocks, restricted basin salts, and Niagaran pinnacle reefs. Quaternary glacial events and the development of today’s modern landscapes are also discussed.
