All covered sources must document worst-case release scenarios per 40 CFR §68.25 (full vessel quantity release assumptions for toxic gases, 1 cm pool spill for toxic liquids, 10% yield VCE for flammables). Program 2 and 3 processes must also analyze at least one alternative release scenario per covered process. Scenarios must be reviewed and updated at minimum every five years, and within 6 months if operational changes alter endpoint distances by a factor of two or more.
