1. Quantitative analysis of site-specific pipeline risk for school property development in CA1 2. Inputs: 2.1 size and pressure of the pipeline (we assumed a gas pipeline) 2.2 distance from the property line to the pipeline 3. Baseline assumptions: 3.1 a single receptor in the middle of the property line closest to the pipeline 2 hours/day, 180 days/year (4% of year) 3.2 use average pipeline incident probabilities / mile 4. Decision tree of possible scenarios: 4.1 1" leaks and total ruptures; ignition or not 4.2 If ignition: Jet Fires, Flash Fires, or Explosions 4.2.1 Note: total ruptures with jet fires are 99% of fatalities in the Protocol 5. Criteria: Less than 1 fatality in a million years.
