  1. The 12-month total for any given year is somewhat higher than the annual load target for that year because the monthly targets for the months of September, October, November and December have been adjusted to allow for greater selenium discharge than would typically occur. This adjustment has been made to provide greater selenium management flexibility during months when the assimilative capacity of the river is sufficient to sustain this greater load.
  2. The annual 2nd year load target is based on the average annual loads discharged over a 9-year historical period (1986-1994) which includes both wet and dry year data, as well as full and partial water supply data. It is divided by month based on the average historical distribution of selenium loads except where the Total Maximum Monthly Load (TMML) calculation (using a 1-in-5 month violation rate) allows for a greater monthly load.
  3. The 3rd year annual load target is based on a 5% reduction of the average historical loads. The 5% reduction is applied equally across all months except where the TMML (using a 1-in-5 month violation rate) allows for greater monthly selenium loads.
  4. The 4th year annual load target is based on a 10% reduction of the average historical loads. The 10% is applied equally across all months except where the TMML (using a 1-in-5 month violation rate) allows for greater monthly selenium loads.
  5. The 5th year annual load target is based on a 15% reduction from the average historical load. The 15% is applied equally across all months, except where the TMML (using a 1-in-5 month violation rate) allows for greater monthly selenium loads.
