Analyze and Document Data 67 HMCFS information according to the hazard analysis process dimensions listed in CPG 101, as follows: 1. Probability or frequency of occurrence (e.g., what are the frequencies of hazmat transport over different network segments? What are the incident rates?). 2. Magnitude--the physical force associated with the hazard or threat (e.g., how much hazmat might be released in a hazmat transport incident?). 3. Intensity/severity--the impact or damage expected (e.g., what are explosive or toxic impacts associated with potential hazmat releases?). 4. Duration--how long the hazard or threat will be active (e.g., do hazmat releases disperse/ neutralize on their own or require neutralization?). 5. Speed of onset--how fast the hazard or threat can impact the public (e.g., hazmat incidents are typically immediately acute, with incident timeframes of minutes to several hours). 6. Time available to warn (e.g., warning time for a hazmat release may depend on distance to populations, environmental conditions, topography, etc.). 7. Location of the event--an area of interest or a specific or indeterminate site or facility (e.g., ability to define individual locations or segments of interest may depend on network speci- ficity covered in the HMCFS). 8. Potential size of affected area--(e.g., initial isolation zones) affected by hazmat characteristics, environmental conditions, and topography. See the Technical Guidance for Hazards Analysis: Emergency Planning for Extremely Hazardous Substances (27) for examples of matrices used to summarize hazmat release information, worked examples, and information about chemical hazards. Considerations for Summarizing HMCFS Information FEMA's CPG 101 suggests validation steps for emergency plans. Some of these steps can be adapted as considerations for summarizing HMCFS information as follows: Is the HMCFS information sufficient to inform and accomplish emergency prevention, preparedness, response, and recovery planning? Is the information consistent with the HMCFS objectives? Does it adequately address them? Does the HMCFS information comply with assignments and guidance from lead- ership and management? Are the assumptions valid? Is the HMCFS structured in a way that lends consideration to homeland security and political supportability for emergency planning? 6.5 HMCFS Content The HMCFS report is prepared by the project team and should be a stand-alone document that can be readily integrated into a community's emergency plans. Remember that an HMCFS is not an emergency plan by itself, but it forms a knowledge basis for many different aspects of emergency planning. Based on recommendations in CPG 101 for emergency plan content (with some additions), the following should be included in an HMCFS: Front matter Cover page, including title, data, jurisdictions covered, and authorship; Approval page with appropriate senior officials' signatures;

68 Guidebook for Conducting Local Hazardous Materials Commodity Flow Studies Record of corrections, changes, or modifications (as applicable to individual documents, subsequent HMCFS efforts may focus on different locations, hazards, timeframes, etc. and might not be considered as a change); Record of distribution; List of entities involved the in HMCFS project, including HMCFS core team, HMCFS project team, key personnel, volunteers/data collectors, contractors, etc.; Table of contents and lists of figures and tables; and Situation overview (e.g., an executive summary of HMCFS information). Main document Purpose (HMCFS objectives); Scope (jurisdiction, modes, and network segments that are included); Background information (e.g., previous or adjacent jurisdiction HMCFS information, geo- graphical and environmental information about jurisdiction and communities; critical facility locations, etc.); Methodology (overview of data collection methods, sampling, and precision); HMCFS outcomes (the "meat" of the document--text, matrices, lists, tables, charts, graphs, maps, etc.--for different materials classifications, modes, and network segments, as applicable); Assumptions and limitations (e.g., an HMCFS is a snapshot of hazmat commodity flows in a community at specific times and locations--does the hazard analysis assume that obser- vations are consistent with other times and/or locations?); Conclusions and recommendations, including identification of most frequent or greatest threats, needs for additional intelligence, etc.; and References, including all existing data sources, reports, statistics, and documents that were used--references should include author, performing agency, title, report or series volume and number, publication date, publisher, and other information as applicable. Additional information may be included in appendices including hazmat transportation reg- ulations and requirements, images, and other information (such as sampling forms or schedules) not included in main body of the HMCFS document.
