## CONSEQUENCE ASSESSMENT

- Adequacy of Consequence Assessment Model
- Before any model is deemed appropriate for a specific application
- Evaluation of appropriateness of assumptions conducted
- Documentation of evaluation results in a modeling protocol
- Commensurate with present quantities of hazardous materials in facility
- Adequately characterizes transport and dispersion of materials during a release to ensure appropriate protective actions
- Accounts for atmospheric spatial and temporal variability
- Provides estimates for any location of interest within and slightly beyond limits of EPZ

## CONSEQUENCE ASSESSMENT

- Facility-specific Considerations/Local Meteorological Factors Affecting Transport and Dispersion in CA Models
- Facility-specific Considerations
- Height of release point (i.e., elevated, ground-level, or mixed-mode)
- Effluent temperature and velocity
- Building wake and stack aerodynamic effects (i.e., plume rise)
- Local Meteorological Factors (Supplemental Measurements)
- Lake breeze or Sea breeze
- Urban heat island
- Mountain/valley winds
- Other terrain effects (katabatic/anabatic winds)
- For chemical accidents, especially with respect to pressurized liquid and gas releases, or releases of deliquescent chemicals
- Both temperature and relative humidity could be required
- Accurate assessment of time-varying source term

## CONSEQUENCE ASSESSMENT

- Availability of “Real-time” Meteorological Parameters for Emergency Response
- Representative of site and intended application
- Extension of general environmental protection program per DOE O 231.1
- Data used in consequence assessments should be collected as 15‐minute averages for use in emergency response applications
- Wind direction/wind speed: Basis for determining where (transport) and when consequences will occur
- Wind speed (dilution) and atmospheric turbulence intensity (dispersion): Basis for determining hazardous material concentration at receptor
- Temperature, humidity, precipitation, barometric pressure and inversion layer height: Affects consequence assessment results as well as plume exposure and ingestion planning protective actions

## CONSEQUENCE ASSESSMENT

- Provision of Critical Information to Offsite Authorities
- Present meteorological conditions
- Forecasted meteorological conditions
- Results of consequence assessments
- Plume arrival time
- Concentrations at key receptors/planning zones
- Protective action recommendations

## HAZARD ASSESSMENT

- Hazard assessments for postulated accidental releases should be made for each downwind direction using conservative meteorological assumptions for each release scenario
- Ground-level release: Coupled slow wind speed and stable atmospheric conditions (e.g., F stability at 1.0 m/sec)
- Elevated releases
- Full range of wind speed-stability class conditions should be evaluated
- Moderate wind speed and neutral atmospheric conditions may be more conservative than a slow wind speed and stable conditions
