This requires: · effective risk communications among the various levels of programmatic and on-site Army and contractor personnel · effective risk communications to technical audiences presentation of materials in language understandable to engineers, technicians, and technical managers presentation of detailed material for QRA/HRA practitioners and risk managers, including emergency preparedness officials and local regulatory groups

Although the absence of a pervasive safety culture that emphasizes agent-related and nonagent-related safety matters equally is not likely to change the QRA public risk estimates, it may significantly increase worker risk. The first step in the Army' s attempt to formalize the risk management process was the publication of the Tooele Chemical Agent Disposal Facility Risk Management Plan in April 1995 (U.S.

The plan also includes a "Compliance Matrix" that identifies site implementing documents used to meet the requirements listed in the program requirements document cited above (U.S.

In general, the Stockpile Committee agrees with the proposed management of change process developed by the CSDP and encourages its use. As this process is applied to change proposals, the Army will learn a great deal about the utility, benefits, and difficulties of the process, which may lead to improvements.

The draft Guide does indicate that maintaining the Established Configuration is currently the responsibility of the PMCD; that updating the QRA and HRA is the responsibility of the Army' s Risk Management and Quality Assurance Office; and that significant changes that impact risk need to be closely coordinated with emergency preparedness personnel, environmental managers, and the public. However, the coordination and chain of management responsibilities are not clearly defined.

First, the lower fuel volume and resultant lower weight have increased the seismic capacity of the LPG tank to the point that only much larger accelerations can cause the anchorage to fail and cause a gas leak. Second, even if the tank fails, the lower fuel quantity reduces the likelihood of an LPG explosion that would be significant enough to cause an agent release.

Therefore, the risk management plan will identify ACAMS monitoring in the MPF exit airlock as a critical activity that requires special attention during operation. Summary While QRA models were being developed, interactions between the PMCD, the TOCDF staff, and the QRA team led to improvements in the QRA analysis as well as to refinements in facility operations.

The need for sitespecific evaluations derives from variations in sitespecific factors, such as the types of chemical agents and munitions to be processed, the proximity of popu lation, and different meteorological conditions. The PFS can enter the new management of change process as a proposed change to the baseline system in one of two ways: · a way to achieve regulatory compliance if the HRA indicates that the existing system does not comply with health risk standards because of anticipated levels of pollutants in emissions · a safety improvement of the existing baseline system configuration (i.e., by reducing risk estimated by the QRA)

to the atmosphere at higher concentrations than are generated during normal operations with no filter · additional plant downtime because of gas handling equipment failures and the resulting extension of the stockpile storage risk (delays in processing automatically result in increased risk from storage) · worker exposure to accumulated hazardous contaminants during replacement and disposal of the carbon filters If there were a sudden release of agent that had accumulated on the filter, the concentrations could be above the lower detection limit.
