While recognized standards exist for the systematic safety analysis of potential spills or releases from LNG (Liquefied Natural Gas) storage terminals and facilities on land, no equivalent set of standards or guidance exists for the evaluation of the safety or consequences from LNG spills over water. Heightened security awareness and energy surety issues have increased industry's and the public's attention to these activities. The report reviews several existing studies of LNG spills with respect to their assumptions, inputs, models, and experimental data. Based on this review and further analysis, the report provides guidance on the appropriateness of models, assumptions, and risk management to address public safety and property relative to a potential LNG spill over water.

Vadose Zone Monitoring System (VZMS) was used for the long-term performance assessment of a corrective action management unit (CAMU) containment cell at Sandia National Laboratories, New Mexico. A cost saving of approximately $200 million was realized by utilization of the CAMU versus off-site waste disposition. The VZMS permits the analysis of volatile organic compounds (VOC) concentrations in the soil gas directly underlying the containment cell. The configuration of the VZMS allowed for changes in the requirements for selected monitoring components, monitoring frequency and level of sensitivity.
