A Quantitative Framework for Long-term Performance Assessment of Waste Management Infrastructure using Hazard Analysis Method

当前和拟议的自然灾害损失估算方法（HAZUS）侧重于传统结构，如建筑物、公用设施和交通结构，如道路和桥梁。该项目侧重于开发方法，以解决与HAZUS相关的极端事件（人为或自然）对废物遏制系统造成的损害。对废物管理设施的破坏可能导致剧毒污染物排放到环境中。自2001年9月11日事件以来，这些问题变得更加重要。这些设施的设计使用寿命从10年到200年不等，当设施位于地震活动频繁的地区时，这足以考虑其脆弱性。具有讽刺意味的是，大多数地震易发地区的特点是人口密度高，并通过家庭和工业活动产生大量废物。这可能导致附近的废物管理设施高度集中，这些设施一旦遭到破坏，可能对易受灾地区的居民构成健康和环境风险。在这个项目中，将制定定量方法，以便将评估美国废物遏制设施潜在损害的能力纳入HAZUS。最重要的目标是能够估计这种系统对故意和自然威胁的脆弱性。性能，描述污染物的可能释放量，在某些情况下，系统结构稳定性，将使用威布尔形状和尺度参数进行索引。研究内容包括分析安全壳系统的结构，以确定部件之间的串联和并联连接的范围；开发一种方法来表示构成密封系统内运输介质的材料的退化时间函数；耦合地震和其他瞬态事件的发生和破坏；开发重大压力源筛选系统；制订运输评估子模块，其架构须足够开放，以容纳现有的子模型；在污染物可能释放量与生态系统/人类健康暴露/风险评估方法之间建立定量联系。这项研究的更广泛影响包括有计划地将其结果用于向地方、州和联邦机构以及私营公司提供技术援助，帮助他们在敏感环境中设计、选址和操作废物管理设施。该项目涉及研究、培训三名学生（包括妇女和少数民族）、发展和参与这一综合自然灾害/环境安全项目的实践人员。

Abstract - A Quantitative Framework for Long-term Performance Assessment of Waste Management Infrastructure Using Hazard Analysis MethodThe current and proposed Natural Hazard Loss Estimation Methodology (HAZUS) focuses on traditional structures such as buildings, utilities and transportation structures, e.g., roads and bridges. This project focuses on the development of methodologies to address damages to waste containment systems due to extreme events (human-induced or natural) for linkage with HAZUS. Damage to waste management facilities can result in the release of highly toxic contaminants into the environment. These issues here become even more important since the events of September 11, 2001. The design service lives of these facilities range from about 10 to 200 years, which is significant enough to warrant consideration of vulnerability when the facility is located in areas of significant seismic activity. Ironically, high population densities characterize most of the earthquake-prone areas and generate high volumes of waste through domestic and industrial activities. This may lead to high concentrations of waste management facilities nearby, which when damaged may pose health and environmental risks to residents of disaster-prone areas. In this project, quantitative methodologies will be developed to enable integration into HAZUS the capability to assess potential damage to waste containment facilities in the United States. The overriding objective is to enable the estimation of the vulnerabilities of such system to intentional and natural threats. Performance, described in terms of probable release volumes of contaminants and, in some cases, system structural stability, will be indexed using Weibull shape and scale parameters. Research elements include analyses of containment system configurations to establish the ranges of series and parallel linkages among components with respect to functions; development of a methodology for representing deterioration-time functions for materials that constitute the transport media within containment systems; coupling the occurrence and damage from earthquakes and other transient events; development of a screening system for significant stressors; formulation of a transport assessment sub-module with an architecture open enough to accommodate existing submodels; and establishment of quantitative linkages between probable release volumes of contaminants and ecosystem/human health exposure/risk assessment methods.The broader impacts of this research includes the planned use of its results in technical assistance to local, state and federal agencies, and private firms on the design, siting, and operation of waste management facilities in sensitive environments. This project involves research, training of three students including women and minorities, development and engagement of practicing personnel in this composite natural disaster/environmental security program.
