SECTION I: GENERAL INFORMATION AND LEGAL AUTHORITY I. General Information and Legal Authority. A. Introduction. The Superfund Amendments and Reauthorization Act (SARA) of 1986, Public Law 99-499, Title III, which is also known as Emergency Planning Community Right-To-Know Act (EPCRA) established requirements for political subdivisions to prepare emergency response plans for specified hazardous materials that might be found being manufactured, used, stored, or transported in the community. B. Objective. The objective of the SARA Title III legislation is to enhance community emergency preparedness through a process involving the assessment of the potential impact of an uncontrolled release of hazardous materials on a jurisdiction and the development of an appropriate Hazardous Materials Emergency Response Plan (HMERP). C. Goals. This HMERP was developed to satisfy the requirements of the federal legislation as well as to achieve the following goals: 1. To be published as the result of a joint effort of Prince William County, the City of Manassas, and the City of Manassas Park. 2. To detail all aspects of the joint jurisdictional program for dealing with hazardous materials incidents and emergencies. 3. To serve as a hazard specific annex to each member jurisdiction s emergency operations plan (EOP) that contains specific technical information regarding hazardous materials facilities and transportation routes within the member jurisdiction s boundaries. 4. To be available as a supplemental resource to augment the existing emergency response and disaster management procedures. D. Legal Authority and References. Authority for the development and implementation of both the joint Local Emergency Planning Committee (LEPC) and the HMERP is derived from federal and state statues as well as local government implementing resolutions. The following references are the principal laws and regulations governing hazardous material emergency planning and preparedness. Revised: 07/07 Change: 10 1

SECTION IX: HAZARDS ANALYSIS I. Hazards Analysis. A. Introduction. 1. The hazards analysis for each SARA reporting facility was conducted in accordance with the procedures contained in the federal publications listed below: Technical Guidance for Hazards Analysis: Emergency Planning for Extremely Hazardous Substances, December 1987. NRT-1 Hazardous Materials Emergency Planning Guide, March 1987. 2. Facilities selected for analysis were identified either through prior knowledge of the facility, receipt and review of Tier I or Tier II reports, or as a result of a routine fire safety inspection or visit. 3. Facilities reporting extremely hazardous substances (EHS) at or above the threshold planning quantity (TPQ) were considered to pose a potential offsite hazard and were subjected to a risk assessment. 4. Facilities reporting hazardous substances (HS) were subjected to a risk assessment only if the hazard analysis indicated a significant potential threat. B. Hazard Analysis. Hazard analysis is the process of identifying the materials at a facility or in transportation that may pose a hazard to the community. The following information is required to assess a chemical hazard. 1. Type of chemical. 2. Location of chemical. 3. Quantity of chemical. 4. Physical state. 5. Container type and size. 6. Hazard category. Revised: 01/00 Change: 3 30

SECTION IX: HAZARDS ANALYSIS C. Vulnerability Analysis. Vulnerability analysis is the process that identifies the type and number of critical facilities, human population, and environmental resources in a specified area called the vulnerable zone around a facility that has been the subject of a hazards analysis. D. Risk Analysis. 1. Risk analysis is the consideration of the probability of the occurrence of a release of an identified hazard and the impact of such a release on the critical facilities, population, and environment in the vulnerable zone. 2. The results of the hazards, vulnerability, and risk analysis are presented as a detailed risk assessment for each EHS facility (Section X) and for selected HS facilities (Section XI). Section XII contains risk assessments for transportation modes and routes. E. Ongoing Hazards Analysis and Risk Assessment. 1. Procedures have been established to monitor the status of hazardous materials in the LEPC jurisdiction and to identify developments that necessitate changing existing or preparing new risk assessments. 2. Monitoring the status of hazardous materials includes the following: a) Inquiries and referrals from the Planning Office and Zoning Office. b) Review of special use (SUP) and hazardous use (HUP) permit applications. c) Identification of facility hazards during building construction plan review. d) Identification of hazards during field fire safety inspections. e) Surveys of local businesses (Business Hazard Evaluation and Survey Form {Appendix IV}). 3.
