建设项目环境影响回顾性评价探讨

阐述了建设项目环境影响回顾性评价的目的、意义、项目类型的确定及评价时机的选择，重点明确了回顾性评价的程序和内容，以及如何提高回顾性环评针对性的方法，并得出回顾性环境影响评价是对环评质量控制的有效手段，可以有效监督建设单位落实环评中规定及环保主管部门批复的环保措施的结论。     

环境影响回顾评价工作初探

环境影响回顾评价，就是对工程建成运行后的环境影响进行评价，以便了解工程兴建对环境的实际影响，掌握环境质量的发展演变过程，并以点带面分为今后兴建同类工程的环境影响评价提供类比依据，环境影响回顾评价的目的，评价方法等在文做了初步探讨。     

建设项目环境影响回顾性评价实例

结合“三同时”项目竣工验收监测，对建设项目进行环境影响回顾性评价。回顾性评价内容包括：调查、核实项目建设的规模、内容以及污染物的治理设施；对应环评本底进行环境质量验证性监测；根据污染物达标排放监测结果，进行环保十持施有效性分析；清洁生产、循环经济执行情况；总量控制、环境管理体系的落实情况；以及公众调查、结论与建议等。     

建设项目环评报告书中存在的水环境监测问题及解决方法

项目建设前的环境质量(包括水环境质量)是环境影响评价的基础,预测项目建设后的环境质量是环境可行性评价结论的依据,环境质量的表征数据是通过环境监测工作取得,环境监测的规范性要求,开展监测要得到的数据必须具备"五性",才能表征某一监测地区的环境质量。由于环境评价的中介服务性,以及时间与经费的关系,对环境监测点位、频次进行压缩与省略,使得监测数据无法保障其代表性,影响建设项目环境影响报告书得出可信的结论。如何保障监测数据的质量,以最少的监测点、最恰当的监测时期、最少的监测频次,取得最有代表性的数据表征建设项目周围的环境质量,从而确保评价依靠的环境质量基础可靠,评价结论可信,是一个值得探讨的问题。

对南京地区建设项目环境影响评价工作问题的探讨

建设项目环境影响报告书审批制度,是我国借鉴美国等国家的环境政策而制定的一项控制新污染,实现经济效益和环境效益协调发展的制度,1979年被列为《中华人民共和国环境保护法》(试行)的一项法律条款。1981年国家环保局颁布的《基本建设环境保护管理办法》,明确了编制建设项目环境影响报告书的工作程序和内容,1986年国家环保局又颁布了重新制定的《建设项目环境保护管理办法》,其后各省陆续制定了实施细则。但是,这项工作还存在许多问题,本文仅就近年来南京地区建设项目“环评”工作存在的问题进行初步探讨。

Post-project analysis: The use of a network diagram for environmental evaluation of the Barekese Dam, Kumasi, Ghana

The paper presents an evaluation of post-project impacts of the Barekese Dam on three riparian communities downstream about 30 years after its construction. A network diagram, which incorporated a mathematical model, was used for impact identification and analysis. The expected environmental impacts, expressed as quantitative weighted impact scores, showed that the dam appeared to have exerted adverse impacts on the environmental quality of the communities. The impacts in the communities, however, increased with relative distances away from the dam and the river suggestive of cumulative impacts transmitted downstream. Strategic measures for improving environmental quality of the communities have been given.

The environmental impact assessment in Chile: Overview,improvements, and comparisons

In this study, we carried out a comparative analysis of the Chilean Environmental Impact Assessment (EIA) system using evaluation criteria compared against three countries to allow for an objective evaluation within the growing demand of society for a more creditable and trustable EIA system.A total of 18 evaluation criteria were selected from the literature, and four new criteria for comparing EIA systems were proposed. The Chilean EIA system was compared to that of Brazil, Spain, and Canada using the following four evaluation criteria categories: EIA Legislation (four criteria), EIA Administration (four criteria), EIA Process (eleven criteria), and After EIA (three criteria). A Hierarchical Agglomerative Cluster Analysis for assessing similarity among the EIA systems of Chile, Canada, and Spain was performed: the similarity being 88%. A Principal Component Analysis shows that only 13 of the selected 22 criteria contribute to the variability of the selected EIA systems. The main strengths of the Chilean EIA system are the existence of Specialized Environmental Courts for the resolution of disputes and Appeal options before execution. The identified weaknesses are an EIA system with high centralization at the national level, the absence of consideration of project alternatives, no requirement for scoping, and that the process of Strategic Environmental Assessment is not binding.Modifications to the Environmental Impact Assessment System Regulation are proposed by authors as feasible improvements particularly in relation to, Decentralization of the EIA system, Alternatives for design, Scoping incorporation, Register of reviewers of baseline information, and the public information process and post-evaluation.The method used seeks out to serve as guidance for countries with similar environmental and social contexts, as well as environmental legislation improvement needs.

Framing effectiveness in impact assessment: Discourse accommodation in controversial infrastructure development

There is ongoing debate about the effectiveness of impact assessment tools, which matters both because of the threat to future practice of the tools which are frequently perceived to be ineffective, and because of the disillusionment that can ensue, and controversy generated, amongst stakeholders in a decision context where opportunities for meaningful debate have not been provided. In this article we regard debate about the meaning of effectiveness in impact assessment as an inevitable consequence of increased participation in environmental decision-making, and therefore frame effectiveness based on an inclusive democracy role to mean the extent to which impact assessment can accommodate civil society discourse. Our aim is to investigate effectiveness based on this framing by looking at one type of impact assessment – environmental impact assessment (EIA) – in two controversial project proposals: the HS2 rail network in England; and the A4DS motorway in the Netherlands. Documentary analysis and interviews held with key civil society stakeholders have been deployed to identify discourses that were mobilised in the cases. EIA was found to be able to accommodate only one out of four discourses that were identified; for the other three it did not provide the space for the arguments that characterised opposition. The conclusion in relation to debate on framings of effectiveness is that EIA will not be considered effective by the majority of stakeholders. EIA was established to support decision-making through a better understanding of impacts, so its ineffectiveness is unsurprising when its role is perceived to be broader. However, there remains a need to map discourses in different decision contexts and to analyse the extent to which the range of discourses are accommodated throughout the decision process, and the role of impact assessment in those processes, before recommendations can be made to either improve impact assessment effectiveness, or whether it is simply perceptions of effectiveness that need to be improved.

Environmental impact assessment in the Philippines: 1977–1985

During 1977 a Philippine environmental impact statement (EIS) system was established and the National Environmental Protection Council (NEPC) was formed to develop environmental policy. Several months after its creation, NEPC was given responsibility to certify that proposed projects met EIS system regulations. With few exceptions, this requirement to gain NEPC's approval was not taken seriously by agencies. The poor record of agency compliance with the EIS system is explained by the absence of ‘controls’ to force thorough assessments. Judicial controls are absent. Procedural and evaluative controls are in place, but NEPC has neither the budget nor the political power to enforce them. Although the national EIS system is ineffective, agencies sometimes conduct informal, ad hoc environmental assessments in response to instrumental controls exercised by international funding organizations, professional controls exerted by planners, and public controls brought about by individuals and groups who would be adversely affected by projects.     

Review and environmental impact assessment of green technologies for base courses in bituminous pavements

This paper provides a critical review of different approaches applied in the Belgian asphalt sector in order to reduce the environmental impact of bituminous road construction works. The focus is on (1) reusing reclaimed asphalt pavement, (2) reducing the asphalt production temperature, and (3) prolonging the service life of the pavement. Environmental impact assessment of these methods is necessary to be able to compare these approaches and understand better the ability to reduce the environmental impact during the life cycle of the road pavement. Attention should be drawn to the possible shift in environmental impact between various life cycle stages, e.g., raw material production, asphalt production, or waste treatment. Life cycle assessment is necessary to adequately assess the environmental impact of these approaches over the entire service life of the bituminous pavement. The three approaches and their implementation in the road sector in Flanders (region in Belgium) are described and the main findings from life cycle assessment studies on these subjects are discussed. It was found from the review that using reclaimed asphalt pavement in new bituminous mixtures might yield significant environmental gains. The environmental impact of the application of warm mix asphalt technologies, on the other hand, depends on the technique used.
