20 THE IETHBRIDGE HERALD Thursday, May 17, 1973 U.S. blasts designed to free underground gas deposits RIO BLANCO, Colo. (AP) Three nuclear explosions each equal to tons of TNT will shake the Colorado underground today as the United Slates tries something new in its thirst for energy. The blast, called Project Eio Blanco, is designed to free natu- ral gas trapped in underground rock formations. Supporters of the project know there is enough gas trapped beneath the Rocky Mountains to supply total U.S. gas needs for five years. They don't know whether nu- clear explosions are the key to making the gas available to man. Nuclear explosions have been tried before in efforts to free rich underground deposits of natural New Mexico in 1967 and Colorado in 1969. The 1967 blast provided tech- nical data but little gas. The 1969 attempt produced a 108-day flow of gas, but the results didn't demonstrate conclusively whether the method is econom- ical. Those attempts involved only one nuclear blast. Tns latest project will involve three simul- taneous explosions in sparsely populated ranch country 130 miles southwest of Denver. Hal Aronson, nee-president of CER Geonuclear Corp., the Las Vegas, Nev., firm which is the industrial sponsor of the blast, says "conventional means" for freeing the wealth of under- ground natural gas have failed. He said Rio Blanco, if suc- cessful, could show that similar exulosions can be used to de- velop the vast natural gas de- posits through the Rocky Moun- tain region. The key to the projects suc- ces will be fractures in the ex- tremely hard surrounding rock. These breaks are supposed to free about .17.5 billion cubic feet of gas during 25 years, Aronson said. Rio Blanco is part of the U.S. Atomic Energy Commission's Plowshare program, aimed at developing peacetime uses of atomic energy. Organizers say hundreds of blasts will be re- quired to develop the region's gas supplies if Rio Blanco is a success. FEAR RADIATION Senator Floyd Hakell (Dem.- Colo.) has been a strong critic of Rio Blanco, saying there is too much risk in the test. "When the supporters say the radiation will be so small as to be insignificant, I ask everyone to bear in mind that some of these radioactive substances last almost Haskell said. A lawsuit was filed to stop the blast, but a federal judge Mon- day refused to issue an in- junction to block it. The suit claimed that the Col- orado water pollution control commission approved the proj- ect without sufficient evidence, but most opposition centres on environmental concerns and the threat of radiation damage.
