  (2)  The aggregate nonblended gasoline gallonage, which is the aggregate number of gallons of nonblended ethanol gasoline.
  b.  The aggregate ethanol gallonage is the total number of gallons of ethanol which is a component of ethanol blended gasoline which all retail dealers sell and dispense from motor fuel pumps as provided in paragraph “a” during a twelve-month period beginning January 1 and ending December 31.
  5.  a.  The aggregate diesel fuel gallonage is the total number of gallons of diesel fuel which all retail dealers sell and dispense from all motor fuel pumps operated by the retail dealers in this state during a twelve-month period beginning January 1 and ending December 31. The aggregate diesel fuel gallonage is divided into the following classifications:

  6.  a.  The aggregate ethanol distribution percentage is the aggregate ethanol gallonage expressed as a percentage of the aggregate gasoline gallonage calculated for a twelve-month period beginning January 1 and ending December 31.
  b.  The aggregate per gallon distribution percentage is the aggregate ethanol blended gasoline gallonage expressed as a percentage of the aggregate gasoline gallonage calculated for a twelve-month period beginning January 1 and ending December 31.
  7.  a.  The aggregate biodiesel distribution percentage is the aggregate biodiesel gallonage expressed as a percentage of the aggregate diesel fuel gallonage calculated for a twelve-month period beginning January 1 and ending December 31.
  b.  The aggregate per gallon distribution percentage is the aggregate biodiesel blended fuel gallonage expressed as a percentage of the aggregate diesel fuel gallonage calculated for a twelve-month period beginning January 1 and ending December 31.
  8.  The aggregate biofuel distribution percentage is the sum of the aggregate ethanol gallonage plus the aggregate biodiesel gallonage expressed as a percentage of the sum of the aggregate gasoline gallonage plus the aggregate diesel fuel gallonage calculated for a twelve-month period beginning January 1 and ending December 31.
