Technical Guidance for Hazards Analysis: Emergency Planning for Extremely Hazardous Substances [open pdf - 4MB]
"The purpose of this guide is to help local emergency planning committees (LEPCs) conduct site-specific hazards analyses for airborne releases of extremely hazardous substances (EHSs) as required by Title Ill of the Superfund Amendments and Reauthorization Act of 1986 (SARA), also known as the Emergency Planning and Community Right-to-Know Act (EPCRA) . Although these substances may also threaten property and the environment, this guide is primarily concerned with lethal effects of airborne substances on humans. An expanded version of this document which will also address hazards such as flammability, explosivity, corrosivity, and reactivity, is planned. The hazards analysis guidance in this present document will help to identify potential problems and serve as the foundation for planning and prevention efforts with emphasis on EHSs. […] This document represents a joint effort by the Environmental Protection Agency (EPA), the Federal Emergency Management Agency (FEMA), and the Department of Transportation (DOT) to provide coordinated and coherent technical guidance. Although this guide can be useful to all community and industry planners, it is intended especially for LEPCs established under the provisions of SARA. The three steps of hazards analysis-hazards identification, vulnerability analysis, and risk analysis-provide a decision-making process for the LEPCs to follow as they undertake the development of comprehensive emergency plans mandated by SARA Title Ill. This chapter includes a description of: the relationship of this guide to general planning guidance, a general description of hazards analysis, the legislative and programmatic background for this technical guidance, and an overview of the remaining chapters."
