The Cumulative Impacts Of Management Decisions On Nitrogen Loading To The Rhode Island Salt Ponds, Laura M. Ernst Jan 1996

The Cumulative Impacts Of Management Decisions On Nitrogen Loading To The Rhode Island Salt Ponds, Laura M. Ernst

Theses and Major Papers

Calculations and measurements of nitrogen in groundwater, stream flow and atmospheric deposition were used to see if the cumulative impacts of management decisions over a fifteen year period of time resulted in measurable changes in nitrogen loading to six of the salt ponds on the south shore of Rhode Island. The changes in the source and transmission of nitrogen were tested by comparing calculated and measured nitrogen data from 1980 and 1995. The calculated method included a nitrogen budget based on land-use and literature values for nitrogen loss to groundwater. The second method compared concentrations of nitrogen in groundwater taken …


Alyeska, Sullom Voe And The Oil Pollution Act Of 1990: A Comparison Of Tanker Safety Regulation And Environmental Monitoring, Neil V. Kelly Jan 1991

Alyeska, Sullom Voe And The Oil Pollution Act Of 1990: A Comparison Of Tanker Safety Regulation And Environmental Monitoring, Neil V. Kelly

Theses and Major Papers

The Exxon Valdez oil spill in 1989 highlighted deficiencies in the Trans Alaska Pipeline System's (TAPS) marine operation on both regulatory and operational levels. The United States Congress passed the Oil Pollution Act of 1990 to promote the prevention of oil spills and to improve our ability to mitigate the effects of spills that occur. An oil terminal roughly analogous to the TAPS terminal at Valdez, Alaska, exists at Sullom Voe in the Shetland Islands, west of Norway and to the north of Scotland in the North Sea. The Sullom Voe terminal has had an environmental advisory group guiding policy …


State - Federal Relations In The Siting Of Nuclear Power Plants: Towards Greater State Authority, Walter A. Cooper May 1980

State - Federal Relations In The Siting Of Nuclear Power Plants: Towards Greater State Authority, Walter A. Cooper

Theses and Major Papers

The accident at the Three Mile Island (TMI), Pennsylvania nuclear powered electrical generating plant on March 28, 1979 has promoted a great deal of concern and interest in the future of nuclear power in the United States. Such concern is manifested by the unofficial moratorium imposed by the Nuclear Regulatory Commission (NRC) on the granting of new permits for the construction and operation of nuclear plants until the problems presented by the accident at TMI have been addressed. The NRC felt that the accident, at the very least, warranted consideration of a formal moratorium on plant licensing. Although a formal …


Very Large Crude Carriers (Vlccs) And Rules Of The Road For The Prevention Of Collisions, Charles F. Ake Apr 1974

Very Large Crude Carriers (Vlccs) And Rules Of The Road For The Prevention Of Collisions, Charles F. Ake

Theses and Major Papers

A discussion of tanker ship development from the World War II T-2 to the million ton "Delta Ship" concept and an analysis of present and proposed Rules of the Road as they apply to VLCCs.The advantages of size, design characteristics, crew size and automation, propulsion systems and shiphandling characteristics are discussed in general comparitive terms. Projections show tremendous increase not only in the size of tank ships, but also in the size of the world's tanker fleet - approaching 5,000 vessels in the next ten years or so. The increasing size of crude oil carriers and their immense pollution potential …


Environmental Improvement: A Concept For Harbor Maintenance Programs For Long Island Sound, John-Robert Curtin Jan 1973

Environmental Improvement: A Concept For Harbor Maintenance Programs For Long Island Sound, John-Robert Curtin

Theses and Major Papers

This paper suggests a comprehensive approach to maintenance dredging and maintenance dredge disposal for Connecticut in a carefully-regulated manner that will improve, rather than impair, the natural quality of the Sound. It proposes an interim measure that would allow for the continued operation of Connecticuts Commercial Harbor areas until a permanent program, together with the necessary technological advances, can be implemented to handle dredge disposal. This paper is based on data presently available on New Haven Harbor, presented in a report on the environmental quality of dredge spoils proposed to be removed from one area within New Haven Harbor known …
