JUNEAU, Alaska (AP) — Members of a Senate committee on Tuesday pressed industry representatives on what Alaska could expect if the state’s oil tax structure is overhauled.

Sen. Lyman Hoffman, D-Bethel, said the amount of investment needed to eat into or reverse the trend of declining oil is “staggering” — perhaps an additional $3 billion to $5 billion a year. He said he’s not sure it will be achievable with any legislation the Senate Finance Committee devises.
