Assessing Potential Accidental Release Consequences

In the hazard assessment section of the Risk Management Program, facilities must evaluate the possible consequences of an accidental release to nearby communities, schools, hospitals, recreational facilities, and other public and environmentally sensitive areas by predicting the "worst-case" and "alternative" (i.e., more likely) release scenarios. These scenarios can be demonstrated using computer-based models. Facilities must also document past accidents that have occurred at the facility for the last five years.

LandView VI: Electronic Environmental Analysis Tool - This website describes the LandView 6 software which contains a wealth of important environmental information that may be useful for facilities in identifying their site locations and potentially vulnerable populations.

Risk Management Program Guidance for Offsite Consequence Analysis (March 2009) - This is EPA's official RMP offsite consequence analysis guidance. This latest version represents the most up-to-date thinking on the subject, and has been technically reviewed by experts outside of EPA. Although it replaces the previous Offsite Consequence Analysis Guidance, if you have prepared your RMP using the previous guidance, you do not need to revise it based on this new guidance. This revision incorporates several new features, including chemical-specific modeling for ammonia, chlorine, and sulfur dioxide, temperature correction factors for calculations involving evaporating liquids, step-by-step procedures and worksheets to assist users, additional worked examples, and format changes.

It is also available broken down into Chapters and Appendices.
