ABSTRACT: The Environmental Display Manager, EDM, is a development system on an IBM 3090 mainframe at the U.S. EPA National Computer Center in Research Triangle Park, North Carolina. EDM provides mapping, display, analysis support, and information management capabilities to workstations located across the United States, and connected to EPA through federal, state, academic, and private communications networks. Through interactive software, EDM can quickly support analyses, create maps and graphics, and generate reports that integrate millions of pieces of environmental data. The concept of EDM is to provide easy access to environmental information, to provide automated environmental analyses and reports, and then to provide data, graphics, images, text, and documents that can be used by numerous output devices, software packages, and computers. The mapping cumponent works with an electronic version of the 54,000 7.5 minute quad sheets of the U.S. Geological Survey. The software also works with a hydrographic data base of the surface waters of the United States. With the maps, a user can look at the rivers in any state, can zoom in on a small pond, and can overlay and identify particular features such as industrial waste dischargers and factories. The hydrography allows routing for modeling programs, identification of upstream and downstream components, and linkage of environmental features associated with surface waters. Alternatively, users can query data based on latitude/longitude, city name, EPA permit number, state agency and station code, river name or number, and river cataloging unit. The maps can be overlaid with roads and environmental sites such as: municipal and industrial dischargers, Superfund sites, public drinking water supplies, water quality monitoring stations, stream gages, and city locations. Retrievals from related systems can be performed for selected sites creating graphics showing water quality trends, discharge monitoring reports, and permit discharge limits.  相似文献

The ecological systems of Earth are subjected to a wide array of environmental stresses resulting from human activities. The development of appropriate environmental protection and management policies and the appropriate allocation of resources across environmental stresses require a systematic evaluation of relative risks. The data and methodologies for comprehensive ecological risk assessment do not exist, yet we do have considerable understanding of econological stress-response relationships. A methodology is presented to utilize present knowledge for assignment of relative risks to ecological systems and human welfare from anthropogenic stresses. The resultant priorities, developed for the US Environmental Protection Agency's (EPA) relative risk reduction project, highlight global climate change, habitat alteration, stratospheric ozone depletion, and species depletion as the highest environmental risks, significantly diverging from the present emphasis by EPA and the public on toxic chemical issues. Enhanced attention to ecological issues by EPA and development of ecological risk assessment methodologies that value ecological and economic issues equitably are key recommendations.  相似文献

Is ISO 14001 just for the private sector? The answer is definitely “No.” The survey in this article was conducted to better understand how ISO 14001/Environmental Management Systems (EMSs) was being addressed by state agencies around the country. The survey goals were to determine where the focus on ISO 14001/EMSs is within state government, what the level of interest is, and how far states have progressed toward some form of use or recognition of ISO 14001. During the months that this survey was conducted, the progress at the state and federal levels was remarkable. Many states are aggressively moving forward and encouraging the investigation of ISO 14001 implementation. There is a well coordinated effort between several states (the Multi-State Working Group) to gather data on ISO 14001 effectiveness in a consistent manner. The cooperation between EPA and the states is beginning to solidify, with federal dollars going to state-managed pilot programs, and EPA has stepped forward with a more organized effort led by the Office of Reinvention.  相似文献

ABSTRACT: Maintenance of the more than 24 million septic tanks in the U.S. requires removal and disposal of septage. Disposal options include application to agricultural lands where the nutrients and organic matter can provide soil benefits. However, pathogens and contaminants are also contained in septage. An extensive search turned up very few data on septage quality, and those reveal high variability. The data used by the U.S. Environmental Protection Agency (EPA) in developing regulations had the lowest metal concentrations among the nine data sets that could be compared. Based on these data, EPA assumed that septage could be applied to agricultural land for more than 100 applications before reaching unacceptable cumulative loading of metals. They thus did not establish federal standards for metals in septage, and no monitoring is required under federal rules governing septage disposal. Analysis of the nine data sets we found showed that field site life would be reached in less than 100 applications for most septage and cumulative loading limits established by EPA for sewage sludges will be exceeded in 16 applications for some septage as opposed to the 100 application estimate used by EPA. Determination of acceptable cumulative loading depends on numerous technical and policy considerations. All septage sources reached the more restrictive loading limits such as those established by the New York State Department of Environmental Conservation (NYSDEC) and the recommendations in Cornell publications in less than 100 applications. In one case the cumulative limit for copper was exceeded in a single application. These findings suggest additional data are needed on septage quality and that the federal and state agencies responsible for regulating application of septage to agricultural land should reassess their standards.  相似文献

Efficient regional ozone control strategies for the eastern United States   总被引:1,自引:0,他引:1  
When environmental regulatory bodies formulate control plans, it is incumbent upon them to try to achieve the stated goals in an economically efficient manner. The US Environmental Protection Agency (EPA) is presently developing regulations to limit the influence of transported ozone on areas that are having difficulty meeting the ambient air quality standard. EPA has proposed stringent control measures for emissions of nitrogen oxides (NOx) in 22 states of the eastern US. The strategy would necessitate the use of selective catalytic reduction or similar high-performance technology on almost all major power plants in the region, as well as extensive controls on industrial sources. This paper suggests several alternative approaches that would achieve equal or better environmental improvement at lower cost. These include focusing control efforts on sources closer to the North-east Corridor, pushing controls on close-in sources to a higher level of technology performance, and relaxing the stringency of requirements for states remote from ozone problem areas. All the approaches examined are two to three times more cost-effective than EPA's proposed approach in the North-east Corridor.  相似文献

Assessing ecological risk on a regional scale   总被引:17,自引:0,他引:17  
Society needs a quantitative and systematic way to estimate and compare the impacts of environmental problems that affect large geographic areas. This paper presents an approach for regional risk assessment that combines regional assessment methods and landscape ecology theory with an existing framework for ecological risk assessment. Risk assessment evaluates the effects of an environmental change on a valued natural resource and interprets the significance of those effects in light of the uncertainties identified in each component of the assessment process. Unique and important issues for regional risk assessment are emphasized; these include the definition of the disturbance scenario, the assessment boundary definition, and the spatial heterogeneity of the landscape. Although the research described in this article has been funded wholly or in part by the United States Environmental Protection Agency (EPA) through Interagency Agreement Number DW89932112-01-2 to the U.S. Department of Energy, it has not been subjected to EPA review and therefore does not necessarily reflect the views of EPA and no official endorsement should be inferred.  相似文献

New systems approaches by the U.S. Environmental Protection Agency (EPA) have attempted to prevent and limit environmental damages through multimedia management of resources, energy, and environmental impacts, while engaging communities, environmental groups, facilities, industries, states, and local agencies. Collectively these diverse interests have begun to partner with corporate management to work toward a shared vision of how multimedia management and multistakeholder participation can best evolve in concert with environmental management system approaches. This article analyzes one industry-specific program under the Common Sense Initiative, called an Alternative System of Environmental Protection (ASEP) for the Computers and Electronics Subcommittee. The significance of this working group's attempt to increase regulatory flexibility lies in its collective establishment of an alternative regulatory framework for an entire industry. Contrary to many other EPA single-facility pilot programs, this method cuts across the entire computer and electronics industry. The group hopes to achieve sector-wide regulatory improvements through a process providing funding for shared research, dynamic feedback, and technical assistance, while engaging in multistakeholder relationships with communities, workers, local governmental agencies, and other stakeholders.  相似文献

Environmental decision-making and policy-making at all levels refers necessarily to synthetic, approximate quantification of environmental properties such as vulnerability, conservation status, and ability to recover after perturbation. Knowledge of such properties is essential to informed decision-making, but their definition is controversial and their precise characterization requires investments in research, modeling, and data collection that are only possible in the most developed countries. Environmental agencies and governments worldwide have increasingly requested numerical quantification or semiquantitative ranking of such attributes at the ecosystem, landscape, and country level. We do not have a theory to guide their calculation, in general or specific contexts, particularly with the amount of resources usually available in such cases. As a result, these measures are often calculated with little scientific justification and high subjectivity, and such doubtful approximations are used for critical decision-making. This problem applies particularly to countries with weak economies, such as small island states, where the most precious environmental resources are often concentrated. This paper discusses frameworks for a “least disappointing,” approximate quantification of environmental vulnerability. After a review of recent research and recent attempts to quantify environmental vulnerability, we discuss models and theoretical frameworks for obtaining an approximate, standardizable vulnerability indicator of minimal subjectivity and maximum generality. We also discuss issues of empirical testing and comparability between indicators developed for different environments. To assess the state of the art, we describe an independent ongoing project developed in the South Pacific area and aimed to the comparative evaluation of the vulnerability of arbitrary countries.  相似文献

虽然针对美国《清洁空气法》(CAA)的研究众多,然而诸多研究并未发掘至其之所以先进的核心。CAA之所以先进的关键在于重新分配法律(EPA是其代表)与州政府之间权力与义务的环境质量达标制度。CAA要求在联邦层面构建一个约束美国各州的大气环境质量标准体系,并且以各州的客观环境与发展程度为前提,赋予各州政府一系列的大气环境质量目标。各州政府需要在自身的权限范围内采取行动,从而为这一系列目标向联邦负责。CAA将自身的法律设置分为两大内容(或称两大原则):国家空气质量标准原则与州政府独立实施原则,并将两大原则转化为具体的程序:NAAQS与SIP。代表国家法律的环保署与代表实际环境义务承担者的州政府之间,是互相依赖又互相独立的关系。  相似文献

Developing a collaborative model for environmental planning and management   总被引:9,自引:0,他引:9  
Methods for involving the public in natural resource management are changing as agencies adjust to an increasingly turbulent social and political environment. There is growing interest among managers and scholars in collaborative approaches to public involvement. Collaboration is conceptually defined and elaborated using examples from the natural resource management field. This paper then examines how collaboration theory from the organizational behavior field can help environmental managers to better understand those factors that facilitate and inhibit collaborative solutions to resource problems. A process-oriented model is presented that proposes that collaboration emerges out of an environmental context and then proceeds sequentially through a problem-setting, direction-setting, and structuring phase. Factors constraining collaboration are also specified, including organizational culture and power differentials. Designs for managing collaboration are identified, which include appreciative planning, joint agreements, dialogues, and negotiated settlements. Environmental managers need new skills to manage collaboration within a dynamic social and political environment. Further research is needed to test the propositions outlined here.  相似文献

ABSTRACT: The visualization of water quality data in lakes was achieved by integrating the U.S. Environmental Protection Agency's (EPA) STORET water quality database, lake shoreline polygons from EPA's Reach File (version 3), and the UNIMAP 2-D and 3-D interactive mapping and modeling software. Based on lake name (and state abbreviation), a lake shoreline polygon can be accessed from the Reach File. The coordinates of the polygon are portrayed by the U.S. Geological Survey (USGS) 1:100,000 scale Digital Line Graph (DLG) hydrography layer. This polygon is passed, in turn, to the STORET water quality file. Monitoring stations located within the polygon boundary are extracted along with the complete sampling survey. Specific parameters, such as total phosphorus, pH, ammonia, and optional time and depth restrictions can be selected to build a file of x, y, z1, z1…, zn data which is imported to UNIMAP. Up to four parameters, including depth, can be selected at a time. Within UNIMAP, the data is gridded and then displayed as a 2-D color contour map, 3-D perspective contour map, or 2-D projected time or depth slices. This system operates on the EPA ES9000 mainframe computer located in Research Triangle Park (RIP), North Carolina. LAKEMAP is the culmination of an effort to bridge the gap between the vast array of environmental data collected by the EPA and the complex analytical and display software resident on the mainframe.  相似文献

The U.S. Environmental Protection Agency (EPA) defines environmental justice as the “fair treatment for people of all races, cultures, and incomes, regarding the development of environmental laws, regulations, and policies.” The last decade has focused considerable national attention on the environmental pollution inequity that persists among the nation’s poorest communities. Despite these environmental justice efforts, poor communities continue to face adverse environmental conditions. For the more than 550 Native American communities, the struggle to attain environmental justice is more than a matter of enforcing national laws equitably; it is also a matter of a federal trust duty for the protection of Indian lands and natural resources, honoring a promise that Native American homelands would forever be sustainable. Equally important is the federal promise to assist tribes in managing their reservation environments under their reserved powers of self-government, an attribute that most distinguishes tribes from other communities. The PM Northwest, Inc. (PMNW) dumpsite is located within the boundaries of the Swinomish Indian Reservation in Washington State. Between approximately 1958 and 1970, PMNW contracted with local oil refineries to dispose of hazardous wastes from their operations at the reservation dumpsite. Almost two decades would pass before the Swinomish tribe was able to persuade EPA that a cleanup action under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) was warranted. This article reviews the enduring struggle to achieve Indian environmental justice in the Swinomish homeland, a process that was dependent upon the development of the tribe’s political and environmental management capacity as well as EPA’s eventual acknowledgement that Indian environmental justice is integrally linked to its federal trust responsibility.  相似文献

Focusing on environmental review practice in state departments of transportation in the US, the study examines the practices and effects of stakeholder involvement in scoping processes conducted under the National Environmental Policy Act (NEPA). Based on a survey of environmental review staff in 46 of the 50 states, the study finds variation in approaches used by states and relatively high levels of perceived effectiveness. The findings include a number of internal and external factors that contribute to effectiveness and highlight the impacts of participation on the content and outcomes of scoping processes.  相似文献

The flagship of the Environmental Protection Agency's regulatory reinvention initiative, Project XL has been touted as a regulatory blueprint for a site-specific, performance-based pollution-control system, but widespread complaints about the costs of the program beg the question of whether the costs of tailoring regulations to individual facilities are manageable. To address this question, this paper presents original survey data on a sample of 11 XL projects. We find that the fixed costs of putting in place XL agreements are substantial, averaging over $450,000 per firm. While stakeholder negotiations are widely cited as the principal source for these costs, we find that they actually arise mainly from interaction between participating facilities and the EPA. Moreover, EPA management problems are perceived by our survey respondents as having inflated project development costs. Finally, we find that the key factors that explains differences in costs across XL projects are the scope and complexity of the project proposal. These findings suggest that Project XL favors large firms that can afford to pay significant project development costs, that EPA management problems must be resolved to reduce costs, and that there may be a significant economic bias against complex and innovative proposals—precisely the type of proposals that Project XL was designed to foster in order to improve the efficiency of the regulatory system.  相似文献

ABSTRACT: Environmental response to acidic deposition results from movement of water through the ecosystem. As a part of the environmental studies for acidic deposition sponsored by the U.S. Environmental Protection Agency (EPA), hydrologic classification based on regional baseflow properties was done. To obtain the amount of baseflow, a flow separation method was developed based on the division of streamflows into “baseflow” and “other” runoff sources. Because of the differences in the flow paths and exposure duration, the two components were assumed to be associated with distinct geo-chemical responses. Individual annual hydrographs were analyzed using 31 separation slopes to determine the amount of baseflow. A total of 1575 streamflow stations in the Northeastern U.S. were analyzed through the access of a long-term daily stream-flow data base. An interactive computer program was developed to obtain baseflow properties and other hydrologic characteristics of each station. The output from this analysis was used to perform cluster analysis to classify streamflow behaviors. The clustering output showed different regional boundaries than those currently used by the EPA for water quality studies.  相似文献

US environmental controls for industry include numerous regulations that rely on the regulated community to self-identify, monitor, report, or complete other requirements on their own recognizance. These include state- and federal-issued general permits for stormwater discharges associated with industrial activities, effective in 1992, with known incomplete compliance by 2004. Results demonstrate highly incomplete compliance with variation in effectiveness among studied states and urbanized regions. Texas and Oklahoma, administered by US EPA during the research period, have attained higher compliance rates than California, administered by a state agency, or Florida, also administered by US EPA. Specific program designs and implementation strategies employed by states are evaluated for impacts on states' compliance effectiveness.  相似文献

We all knew it was coming, and the proposal has finally arrived. On February 8, 2018, the US Environmental Protection Agency (EPA) announced that EPA Administrator Scott Pruitt signed a proposed rule regarding user fees for the administration of the Toxic Substances Control Act (TSCA). As amended by the Frank Lautenberg Chemical Safety for the 21st Century Act, TSCA provides the EPA the authority to levy fees on certain chemical manufacturers, including importers and processors, to “provide a sustainable source of funding to defray resources that are available for implementation of new responsibilities under the amended law” (EPA, 2018a, p. 1). The EPA states in its press release that these fees:

The ability to access information for use in decision making is a well-recognized need within the context of management sciences. A similar need exists in order to make effective technical decisions pertaining to environmental resource management. Data bases are the principle vehicle by which scientists, engineers, and resource managers store and access environmental information. An integrated data-base mechanism is essential in order for federal agencies to manage programs such as enforcement of the Canadian Environmental Protection Act (CEPA), state of the environment (SOE) reporting, and the environmental assessment and review process (EARP). A data-base structure and data dissemination mechanism under current development within Environment Canada, Conservation and Protection, Atlantic Region, is presented along with some of its operational benefits and constraints.  相似文献
