Pursuant to a congressional request, GAO examined various proposals on how the Department of the Interior's Bureau of Mines could best meet federal needs for helium, focusing on how the accelerated degradation of stored federal helium could result in additional costs to the government.

GAO found that: (1) because the Bureau is not restricting the rate at which helium is being extracted from Cliffside, a natural gas field in Amarillo, Texas, the purity of the remaining helium cloud is being degraded faster than would otherwise occur; (2) Bureau engineers and a petroleum engineering consulting firm agreed that accelerated degradation could be avoided by restricting total extractions from Cliffside to 3 million cubic feet of helium daily; (3) the Bureau can restrict the rate at which privately owned helium can be extracted from Cliffside, under the terms of its storage contracts with private companies, but has not imposed such a restriction, pending a review of a fiscal year (FY) 1989 Bureau study; (4) daily total extractions from Cliffside exceeded 3 million cubic feet 13 percent of the time during a 2-year period from April 1989 to April 1991; and (5) if the helium cloud continues to be degraded at the current rate, the Bureau will incur additional costs of as much as $23.3 million in FY 1991 dollars to extract and refine federal helium from Cliffside through FY 2050.
