- JUNEAU, Alaska (AP) - A U.S. Senate committee has advanced a bill that would provide $50 million to clean up abandoned federal wells on current or former National Petroleum Reserve lands. The money for this is expected to come from the sale of crude helium under the Helium Stewardship Act, which advanced Tuesday. The bulk of the $50 million is expected to go toward cleaning up wells in the Alaska arctic. There are about 90 abandoned wells in the Lower 48, according to information provided by the committee, with estimates that cleanup of those wells could average up to $75,000 each. Sen. Lisa Murkowski, who serves on the committee, had called an Obama administration plan that called for Alaska to help with cleanup costs on lands in this state dead on arrival.
