2017年11月,原环境保护部办公厅发布《关于印发重点排污单位名录管理规定(试行)的通知》,对重点排污单位的基本管理要求和筛选条件作出了详细规定。重点排污单位是国家重点监控企业的替代和延续,成为当前排污许可制度尚未完全成熟阶段环境管理的重要抓手。重点排污单位名录聚焦影响环境质量的主要污染物、排污大户和重大风险源,由设区的市级地方人民政府生态环境主管部门确定,有利于压实地方环保责任。在名录制定和使用过程中存在着部分指导性文件存疑、名录重点不突出、部分重点排污单位无法安装自动监测设备、不能满足新的环境监管需求、名录更新时间滞后、缺少罚则等问题,本文就此进行了深入分析并提出了几点建议。 相似文献

Niagara Mohawk Power Corporation (NMPC), an investor-owned electric and gas utility operating in upstate New York, has incorporated environmental factors into several facets of its operations, including generation and transmission system planning and operations, system electric operations, and system gas operations. This article describes how NMPC has incorporated environmental considerations in its valuation of new and existing generation resources. What makes this effort unique is that not only are existing environmental regulatory requirements reflected in the planning process, but also prospective environmental requirements are incorporated. This article provides an overview of NMPC's generation valuation process and discusses how both existing and future environmental requirements are addressed. 相似文献

Little is known about the legislative process and in particular how this relates to environment in Latin America. This article attemps to partially close this gap by discussing the dynamics of congressional environmental politics in Chile under former President Lagos (2000–2006). At first, this article discusses the role of the executive branch in the legislative process, congressional authority and environmental policy. This sometimes uneasy relationship is explored, and its consequences over environmental politics are discussed. The second part of the article attempts to explain legislator's choices in the area of environmental policy, developing and testing four main hypotheses that eventually help to explain why legislators support/reject laws of positive/negative environmental relevance. Finally, this article draws general conclusions on Chilean congressional politics and environmental policy, to then propose some recommendations on how to improve the process of creating environmental policy in Congress. 相似文献
