OCS development: A community's acceptance of risk

Abstract

Port O'Connor, Texas, a small unincorporated community on the Gulf Coast, was studied to assess the residents’ attitudes toward the potential growth related to Outer Continental Shelf (OCS) development. In contrast to attitudes of residents in many East Coast communities, residents of Port O'Connor do not feel threatened by OCS‐related growth. Rather, the risks they perceive result from increased tourism. They are well familiar with the social costs of tourism. They are less familiar with the social risks involved in increased OCS activities.

In terms of coastal zone management policy, this study highlights the importance of attending to the concerns of local residents for their social structure and way of life. The social risks imposed by increased OCS activity must be considered important factors in plans for OCS development.     

Editorial prologue

Abstract

The economic and environmental consequences of a proposed Louisiana superport have been studied by researchers during the last three years. These studies provided technical information and management alternatives. Management alternatives included state control to avoid multiple superport developments, details for an Environmental Protection Plan, comparisons of onshore and offshore sites, and planning for ancillary development. Policy decisions which resulted include many of the recommendations of the research. It is suggested that environmental research can influence policy decisions and limit the options available to a decision maker provided some legal structure is created, quality control is implemented, and technological and environmental problems are recognized. Various analytical tools, such as energy cost accounting, group critique, and simulation models, have wide application for use in coastal zone management.     

The economic impact of commercial fisheries and marine‐related activities: A critical review of northeastern input‐output studies

Abstract

The application of the input‐output method to regional analysis of coastal zone production and consumption activities is examined. A review of previous Northeastern input‐output studies provides a framework for analyzing selected methodological procedures utilized in this type of analysis. While commercial fishing and other marine‐related activities have been shown to have important economic impact on coastal communities, the review indicates that in certain cases the methodological procedures adopted tended to yield an upward bias to the estimation of economic impacts. Standardization of procedures is recommended for future studies.     

OCS development: A new law and a new beginning

Abstract

This article reviews the conflicts that led to the establishment of a special Congressional Committee on offshore oil and gas exploration, development, and production and the attempted resolution of various issues by that Committee and the Congress in the 1978 Amendments to the Outer Continental Shelf Lands Act of 1953. A short review is provided of the history of Outer Continental Shelf (OCS) development, of the conflict between the federal government and other interested entities and persons, and of the Congressional mechanism to respond to these conflicts. A more detailed analysis is provided of the most significant OCS issues. The article describes the various risks and benefits of offshore activity and the various benefits and risks of proposed changes in the law concerning such development. A review of the Congressional mechanism to assess these risks and benefits and balance them is included in a discussion of the various issues and legislated solutions. Finally, the article notes the need for continuing oversight and review of the benefits and risks and how effective the 1978 Amendments are in balancing them.     

An application of interactive management information systems to environmental planning: Coastal zone management

Recent emphasis in comprehensive planning for coastal zone regions has created the need for more effective tools for information processing and analysis to aid policymakers and planners in developing strategies for preservation of coastal zone areas. New agencies with broad powers have been created at both state and federal levels to deal with growth management in large coastal regions. However, coastal zone management (CZM) agencies have not yet been able to deal effectively with development processes. A “holding action”; is being maintained in the face of mounting pressure by developers, while planners struggle to develop (1) a data base with sufficient detail for planning; (2) a fair and rapid process for reviewing environmental impact statements and granting of development permits; and (3) a system for making the development permit application process more routine. The key to success of the CZM process is the development of a management information system (MIS) created explicitly for CZM. The prototypical system designed by the authors combines graphic display capabilities (i.e., map display) with interactive on‐line computing and large storage‐capacity computers. Problems of data structure development are documented, together with problems of assembling a large‐scale, highly detailed data base. Of particular importance is the need for well‐developed objectives and specifications for the use of computer‐based data in resolving disputes on environmental issues. A set of objectives and specifications for a prototypical coastal zone MIS is developed. The system is described in detail, showing how its capabilities directly address policy questions formulated by coastal zone planners.     

Environmental assessment in the Prc: Third phase of the Qinhuangdao coal port

Abstract

The use of environmental impact assessment (EIA) is relatively recent in the People's Republic of China (PRC). China is committed to a reversal of the environmental degradation resulting from its industrialization and the central government has initiated a requirement for environmental planning and assessment for large development projects. Today large scale harbor developments are subject to the requirements of the National Environmental Protection Law (1979) and the Marine Environmental Law (1982). Because the third phase expansion of the coal port of Qinhuangdao would increase the ports’ capacity to handle coal by 30 to 50 million tons, an EIA was required.

Since 1981, the Environment and Policy Institute of the East‐West Center (EWC), Honolulu, has had a program of research focusing on the environmental impacts of coal transportation. On the basis of workshops in China that centered on the problems associated with planning coal transportation projects, the Ministry of Communications of the PRC invited the EWC to participate in the environmental assessment for the third phase coal port expansion at Qinhuangdao. A 10‐member team with specialities in environmental assessment and port environmental problems from five countries representing the EWC worked with a 25‐member team from four different agencies of the PRC Ministry of Communications.

This article describes the environmental regulations in the PRC that affect this harbor expansion, discusses the process by which the EWC assisted the PRC in the preparation of the environmental assessment and evaluates the assessment product against PRC regulations and U.S. standards. The most important contribution of the EWC was the provision of guidelines adapted from the EIA experience in several countries which will assist the PRC in the environmental evaluation of future pon expansion projects.     

Drops in the bucket? A review of onshore responses to Somali piracy

That piracy needs to be addressed onshore is a widely shared assumption. While the majority of counter-piracy measures focus on the sea, a number of onshore counter-piracy initiatives have been launched. We can observe the seeds of an alternative land-based policy approach. One set of land-based programs aims at strengthening the legal and security state apparatus to better deter and punish pirates. The other set of programs aims at addressing local populations on regional, clan or village levels. Such projects aim at increasing surveillance, sensitizing populations for the consequences of piracy, and providing rehabilitation or alternative livelihood opportunities. In this article, I review the latter type of projects and discuss the promises and difficulties of addressing piracy by such measures. I discuss five major problems: knowledge problems, implementation problems, counterintuitive consequences, tensions towards other parts of counter-piracy strategy, and the securitization of aid.     

The long island response to the risks of outer continental shelf oil production

Abstract

The legal battles employed as a strategy to secure increased environmental safeguards identified by the technical studies demonstrate the role of public opinion in shaping federal actions. This article approaches the question of risk from OCS oil production activities by discussing the methodology developed to identify the probability of impact to the south shore of Long Island from the potential of an oil spill, either from drilling or transport activities. A set of probability curves were developed in accordance with seasonal climatic and current patterns in order to establish a range of hazard zones to enable the development of regulatory policy for the location and relocation of shipping lanes that would minimize direct impact to the near shore waters and coastline of Long Island.     

Coastal land management in New Zealand

Abstract

Although New Zealand has a population of 3 million and a coastline of about 10,000 miles there are already heavy pressures on some parts of it. Historically, subdivisions of less than 10 acres require the setting aside of a one‐chain esplanade reserve as part of a general reserve contribution. Some national and regional parks also include significant areas of coast. Recently the Lands and Survey Department has commenced a detailed study of the coastline. Another very recent development is the requirement of an Environmental Impact Report for all major government works. The Waitemata Harbour has been the subject of a detailed study and the reports are now beginning to appear. There has been a heavy demand for shallow bays and estuaries for sanitary land fill, as well as for dredge fill. The main pressure on the coast at present is for holiday cottage sites and some legislative changes may be necessary. In the future new marinas will probably be considered particularly in relation to the extent they provide for the general public rather than a selected few. Industry is only just beginning to make an impact upon the coast. New power stations, natural gas or thermonuclear, are likely to be located on the coastline and this would bring some environmental problems. Recently, it has been argued that to ensure wise use of the coastline there should be national, rather than local or regional, control by a specially appointed Coastal Commission.     

Evaluation of manatee habitat systems on the northwestern Florida coast

Abstract

Threats to the survival of West Indian manatees (Trichechus manatus) vary throughout their range so that protection of this endangered species requires careful planning on a regional and local basis. The importance and vulnerability of various components of manatee habitats in the Crystal River area of northwestern Florida were assessed, using an ordinal‐combination mapping technique similar to procedures practiced in urban and regional planning. Habitat components were mapped and evaluated in juxtaposition with relevant characteristics of human use of the area, to identify areas of existing and potential manatee/human conflicts in need of reconciliation. Areas evaluated as the most important manatee habitats within this region include Crystal Bay and River, Homosassa River, and the Suwannee River estuary. Existing overlap of human activities with important manatee habitats is most critical near the urban communities of Crystal River and, to a lesser degree, Homosassa Springs. The need for integration of this ecological information into coastal land‐use planning is discussed.     

Coastal energy impact mitigation in the Gulf: The past reviewed and alternatives for the future

Abstract

With the future of the Coastal Energy Impact Program (CEIP) in question and with oil and gas leasing and drilling activities in the Gulf of Mexico expected to increase, the question arises as to how energy impacts are to be mitigated. It is concluded that CEIP has helped to mitigate coastal energy impacts. If it is left unfunded, an alternative would be to provide Outer Continental Shelf (OCS) royalties to states to be used for impact prevention and mitigation.     

Assessing land‐use regulations in coastal wetlands: The case of the long point area,lake Erie,Ontario

Abstract

The first comprehensive attempt at development control along the Canadian Great Lakes shoreline was the 1976 lakeshore regulation policy adopted by the Regional Municipality of Haldimand‐Norfolk on the north Lake Erie shore. This innovative strategy was initiated at the municipal level as a component of the regional land‐use planning process. Determination of efficiency and effectiveness of the policy implementation process is based on analysis of permit approval files. All development applications submitted between 1976 and 1980 in the Turkey Point and Long Point Peninsulas are evaluated. Those areas, the most popular cottaging areas in the region, are most susceptible to flood and erosion hazards. Of the total applications submitted during the four‐year study period, 37 percent were in these areas. The policy was ineffective and inefficient in controlling development in the two peninsulas. Applications were approved in the majority of cases, despite regulatory prohibition of developments in hazard‐susceptible areas. There were lengthy decision‐making delays, often exceeding one year, and frequent violations of regulatory procedures. Recommendations are suggested to improve policy implementation.     

Local environmental management—can it work? A case study of the Virginia Wetlands Act

Abstract

The Virginia Wetlands Act of 1972 provides the localities of Tidewater Virginia an opportunity to participate in the management of the state's coastal wetlands resources. This study attempts to analyze the effectiveness of this legislation and to examine the implications of a local management scheme for coastal resource management on a broader scale. Criteria are also established that can be used to evaluate the effectiveness of such a law. When examined in the light of these criteria, the Virginia Wetlands Act emerges, for the most part, as an effective piece of environmental quality legislation that has had a significant impact on wetlands destruction in the state of Virginia. During the two‐year period following the passage of the Act, wetlands losses through the permitting process showed an 18‐fold decrease from previous estimates. The Wetlands Act appears to have been generally accepted by the public and has resulted in consistently uniform decisions, which have reduced wetlands losses without unduly restricting the necessary and legitimate development of the state's wetlands.

Guidelines for urban development in Louisiana's coastal wetlands

Abstract

Coastal Louisiana is currently experiencing extensive urban growth as its natural resources are exploited. Such growth is projected to continue for the foreseeable future. This article examines problems encountered in developing wetland areas for community use. The urban development process in the coastal zone is examined using a problem‐identification methodology. This methodology consists of examining each of the stages of wetlands development sequentially, determining potential problems and their results, and specifying how the regulatory system for urban development needs strengthening in order to mitigate these problems. For those development practices determined not to be regulated at all or inadequately regulated, local ordinance amendments and other restrictive measures applicable to specific development stages are proposed. The study concludes with a brief discussion of a goals‐oriented process for deriving future urban development regulations for the enhancement of regional planning efforts.     

Design of a novel drilled-and-grouted pile in sand for offshore oil&gas structures

New offshore oil and gas exploration has placed renewed emphasis on developing structures in relatively complex geological conditions. Due to the damaging nature of impact driving, traditional steel piles used to support jacket structures, are not ideally suited to specific soil types, such as carbonate sands. Drilled and grouted piles are commonly used to support structures in these soil conditions. This paper describes a novel drilled pile, which has been developed specifically to provide a cost effective installation process while maintaining the benefits of grouted piles. The installation process negates the need for temporary casing in weak soils and minimizes the number of offshore operations. In this paper, the installation methodology and post-installation performance of a large scale onshore field trial is described. The installation process was successfully demonstrated with a 1.9 m diameter test pile installed in fine sand to 17.7 m depth in under 3 h. The performance of the pile, as measured in a tension static load test, was shown to compare favorably with existing pile design methods.     

The Elliott Bay/Duwamish restoration program: A status report

Injuries to natural resources from the release of hazardous substances into aquatic environments have led to hundreds of millions of dollars in compensatory damages awarded under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and other legislation. The institutional mechanisms for negotiating and carrying out the terms of CERCLA natural resource settlements are still in their infancy, and each case has a unique set of injuries, assigned damages, payout schedules, trustee council membership and operating procedures, and environmental conditions and constraints. One of the settlements that has made significant progress toward large‐scale habitat enhancement has occurred in Elliott Bay, a busy, seriously impacted urban harbor in Washington State. The Elliott Bay case is unique among natural resource injury settlements because of the active involvement of two local governments, the City of Seattle, and Metro, who were named as defendants in a lawsuit brought by the National Oceanic and Atmospheric Administration (NOAA) on behalf of the natural resource trustees of Elliott Bay. Both local governments have maintained, and continue to operate, outfalls that discharge into Elliott Bay, and both entities were subject to attempts to recover damages under CERCLA. Following the filing of the lawsuit over injuries to the natural resources of the estuary, alleged to have resulted from the operation of these outfalls, the parties involved negotiated a consent decree settlement. The Elliott Bay/Duwamish Restoration Program has established a process to redress some of the injuries that were attributed to the operation of these outfalls.
