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.

基于风险分析方法的废物管理基础设施长期性能评估的量化框架目前和建议的自然灾害损失评估方法(HAZUS)侧重于建筑物、公用事业和运输结构(如道路和桥梁)等传统结构。该项目的重点是制定处理极端事件(人为或自然事件)对废物控制系统造成的损害的方法，以便与HAZUS联系起来。对废物管理设施的破坏可能会导致剧毒污染物释放到环境中。自2001年9月11日事件以来，这些问题在这里变得更加重要。这些设施的设计使用寿命从大约10年到200年不等，这一寿命足够重要，足以在设施位于地震活动严重的地区时考虑脆弱性。具有讽刺意味的是，高人口密度是大多数地震多发地区的特点，并通过家庭和工业活动产生大量废物。这可能会导致附近的废物管理设施高度集中，一旦遭到破坏，可能会给灾害多发地区的居民带来健康和环境风险。在该项目中，将开发定量方法，以便能够将评估对美国废物控制设施的潜在损害的能力整合到Hazus中。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。用污染物的可能释放量描述的性能，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来索引。研究内容包括：对安全壳系统结构进行分析，以确定各部件之间在功能上的串联和并联范围；制定一种表示安全壳系统内构成运输媒介的材料的劣化时间函数的方法；将地震和其他瞬时事件的发生和破坏联系起来；开发一个重大应激源筛选系统；制定运输评估子模块，其结构足够开放，可以容纳现有的子模型；这项研究的更广泛影响包括计划使用其结果向地方、州和联邦机构以及私营公司提供技术援助，以设计、选址和运营敏感环境中的废物管理设施。该项目涉及研究、培训包括妇女和少数民族在内的三名学生，发展和参与这一自然灾害/环境安全综合方案的实践人员。
