The gas caps shown only apply when spilling to facilitate juvenile fish passage ("voluntary spill") between April 3rd and August 31st. At all other times, the gas cap is 110%.

TDG instances are calculated based on the rounding methods that Oregon and Washington use, which is described by Oregon at www.deq.state.or.us/wq/pubs/imds/SigFigsIMD.pdf, the bottom of page 3, and by Washington here.
