- In LeakDAS, for all inspection intervals, if the second PPM event between two inspections has a lower PPM, then LeakDAS uses the higher PPM to determine the emission rate. This follows the 1994 Emission Estimation Protocol. Chateau only applies this rule for Retests, which aligns with the 2015 Emissions Estimation Protocol update for Petroleum Refineries.
- If a LookBackPPM event occurred on 9/1/15 and the start date for the reporting period is 1/1/16, LD calculates the slope (emission rate) for the lookback PPM as if it occurred on 1/1/16. Chateau will calculate the slope using the modified trapezoidal method and determine the emission rate as of 1/1/16. See the following Reach Back and Reach Forward example.
