适用范围

4.1 The Eco-RBCA process presented in this guide is a streamlined decision-making process for implementing corrective action protective of ecological resources at chemical release sites in a consistent manner. Eco-RBCA provides a framework for sites not covered under regulatory programs, for sites under regulatory programs that lack guidance, or for sites under programs with guidance that lack detail. Eco-RBCA may also provide a useful framework to help merge an approach when multiple regulatory programs apply.

4.2 Ecological risk assessment is a science-based process that can be used to provide insight for risk management decision-making. Numerous federal and state programs have guidance for conducting ERA. Available regulatory approaches to ERA were reviewed in preparation for the development of this Eco-RBCA guide. Eco-RBCA was designed to be adaptable to the use of a variety of methods for considering risks to relevant ecological receptors and habitats. Some attributes of the standard are:

4.2.1 Use of a tiered approach, including process flow charts to identify critical steps and facilitate the development of an overview of the entire process;

4.2.2 Identification, development, and use of TPDs from Step 1 and throughout the entire Eco-RBCA process;

4.2.3 Indications of the value and timing of stakeholder involvement, recognizing that some regulations require coordination with federal, state, tribal, and natural-resource trustees, and other stakeholders;

4.2.4 Identification of situations under which an ERA may or may not be necessary; and

4.2.5 Identification of decision points where ERA results are used for risk management decision making.

4.3 Activities described in this guide should involve persons with the appropriate skills and expertise. The user may rely on individuals expert in remediation science and technology, ecology/biology, ecotoxicology, ERA practices, and site characterization techniques.

4.4 This guide and supporting appendices provide examples and technical support for the proper application of the Eco-RBCA process. The user should avoid inappropriate actions or use of Eco-RBCA such as:

4.4.1 Prescribing Tier 1 RESC as presumptive remediation cleanup goals rather than as screening criteria or, when appropriate, as site-specific remediation cleanup goals;

4.4.2 Limiting the use of the Eco-RBCA process to Tier 1 evaluation only and not continuing with Tier 2 or Tier 3 evaluations for sites where further tiered evaluation is appropriate;

4.4.3 Placing arbitrary time constraints on the corrective action process that do not reflect the actual urgency and risk posed by the site;

4.4.4 Using......

环境部：生态环境损害鉴定评估技术指南

如果需要开展修复，且基于风险的环境修复目标值低于基线水平，应当修复到基线水平，并根据相关法律规定进一步确认应该承担基线水平与基于风险的环境修复目标值之间损害的责任方，要求责任方采取措施将风险降低到可接受水平；如果需要开展修复，且基于风险的环境修复目标值高于基线水平且均低于现状污染水平，应当修复到基于风险的环境修复目标值，并对基于风险的环境修复目标值与基线水平之间的损害进行评估计算。...

二氧化碳地质封存环境风险评估范围研究中获进展

　　二氧化碳（CO2）捕集、利用和封存（CCUS）是应对气候变化、减少温室气体排放的新兴前沿技术。环境风险评估能够解决CCUS项目的安全性和公众信任等问题，为项目工程的顺利开展提供依据。为规范和指导CCUS项目的环境风险评估工作，环境保护部（现生态环境部）制定了《二氧化碳捕集、利用与封存环境风险评估技术指南（试行）》（以下简称“指南”），并于2016年7月1日起颁布实施。　　...
