For over this period of fifty years we have found out that the reclamation business can be a profitable business.

Due to the heavy nature of our product, How true this statement is - and sometimes, I feel - how it is essential that production facilities be located as unfortunate. Let me illustrate. close as possible to the consuming market. Our people initially felt that we had run into a stone wall Transportation costs double the cost of our product to when we first encountered the "time" argument. An the user every twenty miles that the commodity must be analysis of the factual situation showed that historically hauled.

There seemed to be there exists a ready market for the lands excavated and no reason to consider any other mode of operation. properly reclaimed by the construction aggregate On the other hand, consider the situation enjoyed by the industry. neighbors. Initially, the operations are distant and Furthermore, lakeside residential lots command twice therefore seem to be relatively innocuous. However, the selling price per acre as lots located elsewhere. We every year the mining operations get closer and closer -- have a commercial development overlooking a large the neighbors become more and more unhappy as time lake in North Columbus, Ohio, where an acre lot to passes. It isn't until the operator has reached the limits accommodate the district office of a major oil company of the property, if he is that lucky, that he finally reclaims was sold for a price of $150,000. This payment the area which enhances the value of the adjoining represented twice the original cost of the total tract which properties. encompassed 150 acres. It should have been evident years ago that, considering It would be foolhardy to think that every reclamation the cost of working the whole property, the total cost of project will generate such rewards. But at some date in working the property was essentially the same whether the future, all projects will have greater value than if our the operator started at the plant and worked outbound or operations had not taken place. Furthermore, to be started at the perimeter and worked plantward. economic, reclamation must be done as an integral part Furthermore, I have already pointed out how valuable of the excavation process. So when active operations these lands become after: reclamation.

If we worked the right to excavate on gravel-bearing lands which we from the perimeter inward, we could release reclaimed may purchase. This is not the case. lands as fast as we desired, thereby permitting our company to realize the potential value much sooner. When the public hears the words "sand and gravel", it does not think of "Project Parklands". Instead, it thinks Psychologists tell us that the human body can stand of all the abandoned pits which dot the countryside. intense pain as long as the individual knows that relief is Generally, we can convince the neighbors that when our not far away. On the other hand, that same body will operations are completed, their property values will be tolerate a much lower level of pain if the individual feels enhanced. But the word "when" suggests a time factor, that it is going to get worse.

Previous Work The Brassfield Formation has been studied at least since before 1838 by Owen in Indiana. It was originally correlated with the Clinton of New York by Orton {1871), based on strat­ igraphy and lithology rather than on faunal evidence. Due to differences in fauna, Foerst (1896) proposed a land barrier between the two and proposed the name Montgomery limestone for the typical development in Montgomery County, Ohio. The name lapsed, and in 1906 he renamed the Clinton beds in Ken­ tucky the Brassfield, and three years later he did the same for the Clinton age beds in Ohio.

  • 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.
