Ambient Air Quality As Related To Energy Conversion Facilities, Economic Activity And Population, Walter P. Page

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The paper examines the relationships between ambient air quality and energy conversion facilities, economic activity and population. Additional results are presented from investigation of the relationship between ambient air quality and total emissions from four source categories.

Some Problems With Economic Models Involving Air Pollution, John Hoag, J. David Reed

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

In this paper we consider how economic models have interfaced with environmental problems in three areas: optimal air quality standards, pollution control policy and growth with pollution. The focus is on what has been done and what should be done.

Stabilization Of Uranium Mill Trailings, N. H. Tibbs, D L. Rath, E. E. Otto, L. F. Alsup

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Large volumes of uranium mill tailings are being generated, requiring comprehensive long-term management programs to reduce health and environmental risks. Management programs are available which provide adequate secure long-term storage, but research on innovative concepts is necessary to develop improved, more efficient methods.

Energy Is Not Just Flipping The Switch Any More, Alfred L. Ransome

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The energy industry -- or basically the mining industry -- is becoming more complex and costly. It is imperative that the facts pertaining to the mineral industry be disseminated to the layman; the best method in the long term is by way of science and economics in the schools -- kindergarten through high school. The Mineral Information Committee of the Colorado Section of the SME-AIME in cooperation with the Metro State College, Denver is embarking on such a program, and the newly developed magazine, "RESOURCES", is the vehicle for spreading the message through the classroom.

Carrying Water To Newcastle, Lloyd Lore Wartes

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Western coals, now being shipped by unit trains to eastern and southern markets, contain from 13% to 32% moisture. Drying of these coals at the mine would reduce the cost of coal to the utilities from 10% to 16% IF the railroads do not materially increase rates on higher BTU coal.

The spontaneous combustion of dry coal can be inhibited, and the savings per unit train should range from $1,375,000 to $4,129,000 per year according to the various minimum tonnage rates. The shipment of dried coal will reduce the tonnages being shipped by 15%, or increase the railroad carrying capacity …

Oil Shale Energy And The Environment, Stephen Utter

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Shale oil can be produced from oil shale by true In situ, modified in situ, and surface retorting methods. Both modified in situ and surface methods require mining of the oil shale. The environmental Implications of an oil shale mining industry are reviewed and the impacts upon land use, air and water quality, and ecological systems discussed. The Bureau's mining environmental research program is described and the results to date summarized.

The Impact Of Public Transportation Policy To Affect Energy Conservation (A Case Study), Ali A. Selim, John T. Kretzer, Braja M. Das

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

In order that public transportation policies relating to energy conservation might be identified, correlated, and assessed, a mail survey of local, regional, state, and federal appointed and elected officials was made. This survey also included contacting members of the regional business community. Although the responses received did not constitute the complete survey mailing, they did provide insight to the individual policymaker's perception of what public policy is now in effect and how it was enacted, particularly those pertinent to energy conservation in the transportation sector.

Effective Use Of Bottom Ash As A Geotechnical Material, Braja M. Das, Ali A. Selim, Tom W. Pfeifle

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Some geotechnical properties of bottom ash produced from the burning of North Dakota lignite in a power plant are presented. These properties include grain size distribution, maximum and minimum void ratios, maximum dry density of compaction and optimum moisture content from standard Proctor tests, angle of friction, one-dimensional compressibility, and coefficient of permeability. The geotechnical properties of this bottom ash, as determined from laboratory tests, appear to be comparable to those generally obtained from poorly graded sands and indicate that bottom ash can be used for such works as backfill of retaining structures, construction of highway embankments, and fill material …

Energy Aspects Of Rural School Bus Transportation, Kirk R. Hastain, Frank A. Gerig

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

In an effort to determine the effect of rural school bus transportation on energy consumption, a study was made of a rural school district in Central Missouri. The school district's bus system was studied, records of fuel and maintenance costs were analyzed, and discussion held with supervisor and bus drivers. An effort was made to recommend ways by which energy could be conserved, without jeopardizing the welfare of the students.

Multimodal Analysis Of The Western Coal Transportation System, Kenneth Ebeling, Kam Li

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Points raised in the coal slurry pipeline issue imply a need for an analysis of the multimodal alternatives within the context of the existing western transportation system. In reporting the initial results of the first study of its kind, this paper includes a brief description of the data base and computer routines used to construct a base case and ideal case senerios of the western coal transportation issues.

Transporting Coal In Containers Through Pipeline -- A Feasibility Study, Henry Liu

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A preliminary assessment of the feasibility of transporting coal in containers suspended in water moving through pipes - the concept of hydraulic capsule (container) pipelining (HCP) - is presented. The assessment includes technical (engineering), environmental, social and economic considerations. A tentative conclusion reached is that HCP transportation of coal is technically feasible (although it needs further research and development works), socially and environmentally beneficial, and economically justifiable in a number of situations.
