Selection and integration of environmental impacts in the Danish transport infrastructure assessment process

Transport projects have numerous consequences for the environment, society and economy, and thus an EU Directive has stated a number of impacts that need to be assessed prior to any major intervention. This paper is set in a Danish context where the EU requirements have been adopted in the Environmental Impact Assessment (EIA) regulation along with national requirements. In recent years, however, the EIAs have been criticised for an inconsistent inclusion of impacts and unclear assessment process. A selection of EIAs is for this reason reviewed and compared to the EU Directive and corresponding works in Sweden and the UK to identify potential opportunities for improvements. From the literature study, an overview table with all potential relevant impacts for transport projects is set up to assist the EIA process. For the sake of simplicity and transparency, the impacts selected from this table should, however, be further reduced in number to ensure that only the most important impacts are included in the process. To further increase simplicity and transparency in the EIA process, a novel framework for assessing different types of impacts is proposed. In this framework, a comprehensive decision support tool involving stakeholders is in focus. The framework is supplemented with a procedure for generating objectives and presenting results in an appropriate way to the many stakeholders involved. The impacts overview table and the assessment techniques are applied to a case study to illustrate the process, and finally, conclusions and perspectives for future work within the field are set out.

余杭区环评市场质与价的博弈关系分析

随着《环评法》的颁布实施,环评市场不断扩大,本文针对杭州市余杭区环评价格高低有错、环评质量良莠不齐的现象,分析了环评机构间的环评价格博弈关系、环评机构与环保管理部门间的环评质量博弈关系,并指出环保管理部门适当融入到环评市场中有利于突破＂囚徒困境＂及＂小偷与守卫＂博弈,引导环评市场健康、有序发展。     

加大对重点项目和民生项目建设的环境管理,充分发挥环评在产业结构调整、工业布局优化中的重要作用

加大对重点项目和民生项目建设的环境管理,充分发挥环评在产业结构调整、工业布局优化中的重要作用,是政府和环保部门当前必须认真对待的首要问题。     

一种高架复合路补充安装声屏障车流条件确定方法

某一地面高架复合公路,通车初期由于车流量很小,相对沿线大型保护目标高架部分暂未安装噪声屏障,但相对原有设计增加了提高护栏、采用较低噪声路面、绿化带等有利于减小噪声影响的措施,现欲确定必须补充安装隔声屏障的车流条件。该后评价计算目标的确定,完全可以通过盲的试算确定,但由此需要的工作量将是极为繁重和庞大的。为了提高效率,本文提出一种半理论半经验的方法予以简化。     

房地产新建项目的环境影响预测评价

根据房地产开发项目环境影响评价的方法和准则,分析了新建住宅类建设项目施工期和营运期对环境产生的不良影响,及外环境对住宅小区的环境影响,预测和评价了运营期的大气污染、废水污染及施工期和运营期的噪声污染。结果表明,运营期排放的废水可以满足国家污水排放标准,氮氧化物是运营期大气污染物的主要成分,施工期土石方阶段和结构阶段的噪声排放能满足昼间噪声限值,其余噪声污染全部超出了标准限值。提出了相应的环保措施,总结了住宅建设项目环境影响评价的特点。
