>The legislature increased without a vote of the people, the tax on aircraft fuel from 11 cents to 18 cents per gallon, costing $14 million in its first ten years, for government spending.

For WA most of the time you can just cross this line out of the text and then re-read it to not get your head tongue tied.

Personally I don't think the bolded word should be there either as it reads as if it is costing the state this amount. A more accurate phrase would be "Generating $14 million in tax revenue..."
