ABSTRACT In 1993, an incident involving three vessels near the entrance to Tampa Bay, near St. Petersburg, Florida, resulted in a discharge approximately 300,000 gallons of No. 6. fuel oil into the waters off Egmont Key. The oil contacted the shores from Egmont Key to locations approximately 14 miles to the north. Oil also entered Boca Ciega Bay through John's Pass and impacted four small islands that supported mature overwash mangrove forest. A cooperative damage assessment process was developed between the Responsible Parties (RPs) and the trustees for the natural resources: the state of Florida, the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Fish and Wildlife Service (USFWS). Through the cooperative process, several alternatives for primary and compensatory restoration were developed. In considering alternatives to compensate for impacts to epibenthic communities, fish and bird habitats, wetlands, and mangrove communities, the trustees and the RPs considered purchase of shoreline habitat and restoration of mangrove forest at several sites. The RP developed a proposal to purchase and deed into public ownership in perpetuity, a 10.67-acre parcel of land on the west bank of Cross Bayou in Boca Ciega Bay that had been used as a disposal site for dredge spoil in the past. This site consisted of approximately 5.0 acres of uplands, 4.4 acres of mangrove forest, and 1.4 acres of nonmangrove intertidal and subtidal habitat. The objective of the project was to establish a typical Tampa Bay mangrove forest and a roadside buffer free of exotic plant species. The secondary goals were to establish a typical Tampa Bay salt marsh dominated by smooth cordgrass (Spartina spp.) as a successional precursor to mangrove recruitment by seeds and seedlings. Tidal exchange through the site was reestablished to improve water quality and increase export of mangrove detritus and import of high-quality tidal waters. The project was designed and constructed by the RPs with the approval and supervision of the trustees. The project was completed and title transferred to Pinellas County, Florida in summer 1999. A monitoring program was developed and performance criteria established by trustee representatives and the RPs. The monitoring program currently is being conducted and has met performance criteria to date. This project demonstrates the positive result of trustees and the RPs working together to provide compensation to the environment.

ABSTRACT A strategy is described for establishing a simple, inexpensive monitoring program for determining approximate levels of petroleum hydrocarbons in ambient water collected near intake structures of circulating seawater systems. The ambient water is obtained from the depth of intake using a submersible pump, which delivers the sample stream to a dockside partitioning chamber that provides instantaneous grab samples for analysis. A common hand-operated fluorometer equipped for measuring the oil content of a fluid was standardized using a locally-obtained No. 2 marine diesel fuel; oil concentrations in water samples were quantified as Marine Diesel Equivalents (MDE) in parts-per-billion. Surveys conducted along the central Oregon coast following the March 1999 beaching of the drifting freighter New Carissa off Alsea Bay were conducted in that bay, and in Yaquina Bay about 20 km to the north. No evidence of oil contamination from the beached ship was found. The highest MDE levels occurred within the estuaries, especially in an anchorage for fishing vessels in Yaquina Bay. Higher levels of MDE also were measured upstream of this anchorage in February 2001, following a highway spill of No. 6 heavy fuel from a tank truck crash. Thus, this technique appears to be useful for monitoring oil levels in ambient water near seawater intake structures, and to provide a rational basis for temporarily closing down the circulating seawater system after a local oil spill.

This article evaluates the effect of different human resource management (HRM) practices on organizations’ environmental performance. We develop a model to evaluate the influence of a broad range of HRM practices, including environmental performance criteria in managers’ performance evaluations and two types of internal corporate social responsibility (CSR) practices: socially responsible employee benefits and corporate volunteering practices. To this end, we analyze a sample of 142 manufacturing companies that have completed B Lab’s Impact Assessment process to certify their environmental performance. The results show that including environmental criteria in a higher proportion of managers’ performance evaluations directly impacts organizations’ environmental performance and strengthens the positive effect of other environmental management practices. The findings also demonstrate the direct effects of both types of CSR practices on an organization’s environmental performance. Our study advances recent work on Green HRM and CSR by identifying the specific HRM practices that allow organizations to move from being part of the world’s environmental problem to being part of the solution.

Abstract The Waste Isolation Pilot Plant (WIPP), a US Department of Energy (DOE) facility, is a deep geologic transuranic waste disposal site designed for the safe disposal of transuranic (TRU) wastes generated from the US defense program. Monitoring is a key component of the development and operation of any nuclear repository and is important to the WIPP performance assessment. Initial concerns over the release of radioactive and chemical contaminants from the WIPP led to various monitoring programs, including the independent, academic-based WIPP environmental monitoring (WIPP-EM) program conducted by the New Mexico State University (NMSU) Carlsbad Environmental Monitoring and Research Center (CEMRC) located in Carlsbad, NM. The mission of CEMRC is to develop and implement an independent health and environmental monitoring program in the vicinity of WIPP and make the results easily accessible to the public and all interested parties. Under the WIPP-EM program constituents monitored include: (1) selected radionuclides, elements, and ions of interest in air, soil, vegetation, drinking water, surface water and sediment from within a 100-mile radius of WIPP as well as in the air exiting the WIPP exhaust shaft, and (2) internally deposited radionuclides in the citizenry living within a 100-mile radius of WIPP. This article presents an evaluation of more than tens years of environmental monitoring data that informed the public that there is no evidence of increases in radiological contaminants in the region that could be attributed to releases from the WIPP. Such an extensive monitoring program and constant public engagement is an ideal model for all nuclear waste repositories anywhere in the world.

This study evaluates the effect of prevailing dynamic factors on the sedimentation process in Damietta Harbour along the Nile delta coast of Egypt. The monitoring program spanned the period between 1978 and 1999 and included measurements of waves, currents and bathymetric profiles. The evaluation was based on determination of erosion and accretion rates, current regime, sediment transport, wave characteristics and wave refraction. Results revealed that the predominant wave direction from N-NW sector (86 %) throughout the year is responsible for generation of a longshore eastward current. Less frequent waves from the N-NE sector generate an opposing longshore westward current. The refraction pattern for the prevailing wave direction indicates that the harbour and its navigation channel are located within a divergence of wave orthogonal and in an accretion sediment sink area. The annual net rate of littoral drift on the western side of the harbour is about 1.43 * 105 m3 (accretion), while the annual net rate of littoral drift on the eastern side is about 2.54 * 105 m3 (erosion). Currents fluctuate tremendously in speed and direction, especially during the winter months. Hence, sediment transport takes place in offshore, eastward, and onshore directions. Progressive vector diagrams show that the largest near bottom offshore, onshore and easterly net drift occurs during summer, spring and winter respectively. The onshore sediment transport generated during spring and summer plays an important role in the redistribution of eroded sediments during the winter. The overall study of dynamic factors indicated that the harbour site is characterized by eastern, western, offshore and onshore sediment movements. Therefore, the north-south orientation of the navigation channel, with its depth greater than the surrounding area, interrupts sediment drift from different directions and reduces the current speed. Consequently, the sediments sink within the navigation channel from different directions. The sources of sediments contributing to the siltation process of the harbour and its navigation channels are mainly derived from the Rosetta promontory, Burullus beaches, Damietta promontory and from offshore and the dumping area.

Global warming is causing a major ice retreat from the North Pole. From now on, this retreat allows almost permanent movement between East and West off the coast of the Russian Federation along the Northern Sea Route (NSR). For a long time, navigators have been trying to use this route which significantly reduced the distance between continents. The amount of freight that currently travels on the NSR will inevitably increase in the coming years. To reduce environmental risks, one possible option is not to supply ships with heavy fuel oil. The ships could then be electrically powered and navigate in stages from one port to another along the route to refuel for energy. This electrical energy can be produced on site from renewable energy sources. In this article, a first feasibility analysis is outlined, taking into account the tonnage constraints for navigating on a possible route for the NSR, the cost of energy production and the possible location of several ports of call. Under current economic conditions, the solution would not be profitable as it stands, but should become so at a later stage, which justifies starting to think about a future full electrification of navigation on the NSR, which will also contribute to the economic development of the Russian Federation northernmost regions.

The ageing of offshore infrastructure presents a constant and growing challenge for operators. Ageing is characterised by deterioration, change in operational conditions or accidental damages which, in the severe operational environment offshore, can be significant with serious consequences for installation integrity if not managed adequately and efficiently. An oil field consisting of twelve well head platforms, a living quarter platform (XQ), a flare platform (XFP) and a processing platform (XPA) are the focus of this paper, providing an overview of the integrity assessment process. In order to ensure technical and operational integrity of these ageing facilities, the fitness for service of these offshore structures needs to be maintained. Assessments of the structural integrity of thirteen identified platforms under existing conditions were undertaken as these platforms are either nearing the end of their design life or have exceeded more than 50% of their design life. Information on history, characteristic data, condition data and inspection results were collected to assess the current state and to predict the future state of the facility for possible life extension. The information included but was not limited to as built data, brown fields modifications, additional risers and clamp-on conductors and incorporation of subsea and topside inspection findings. In-service integrity assessments, pushover analyses, corrosion control and cathodic protection assessments and weight control reports were completed to evaluate the integrity of these facilities for requalification to 2019 and life extension to 2030. The analytical models and calculations were updated based on the most recent inspection results and weight control reports. A requalification and life extension report was prepared for each platform to outline the performance criteria acceptance to achieve requalification until 2019 and life extension until 2030. This paper documents the methodology to assess the platform structural integrity in order to evaluate platform integrity for the remaining and extended design life. An overview of various aspects of ageing related to these offshore facilities, representing risk to the integrity, the required procedures and re assessment criteria for deciding on life extension of these facilities is presented. This paper also provides an overall view of the structural requirements, justifications and calibrations of the original design for the life extension to maintain the safety level by means of maintenance and inspection programs balancing the ageing mechanisms and improving the reliability of assessment results.
