Interior Secretary Ken Salazar will announce Monday that his department is temporarily barring the filing of new uranium mining claims on about 1 million acres near the Grand Canyon, an Obama administration official said. The land is being “segregated” for two years so that the department can study whether it should be permanently withdrawn from mining activity, said the official, who requested anonymity because he wasn’t authorized to speak publicly on the matter. – from AP
