_**Evaluation Criterion 2-2**_
- Model appropriate for a intended application and documented in modeling protocol
_**Evaluation Criterion 2-3**_
- For chemical accidents: Accurate assessment of time-varying source term

## CONSEQUENCE ASSESSMENT

_**Evaluation Criterion 2-4**_
- If meteorological measurements at single location cannot adequately represent atmospheric conditions for transport and dispersion computations supplemental measurements should be made

## CONSEQUENCE ASSESSMENT

_**Evaluation Criterion 2-5**_
- Consequence analyses for postulated accidental releases should be made for each downwind direction using conservative meteorological assumptions for each release scenario
- For a ground-level release, these assumptions should include coupled slow wind speed and stable atmospheric conditions (e.g., F stability at 1.0 m/sec)
- For elevated releases, a full range of wind speed-stability class conditions should be evaluated since a moderate wind speed and neutral atmospheric conditions may be more conservative than a slow wind speed and stable conditions
