NUCLEAR CLEANUPThere could be disruption of efforts to close the radioactive waste tanks currently leaking at Hanford Nuclear Reservation. The Department of Energy estimates that it will have to eliminate $92 million for the Office of River Protection at Hanford, which will result in furloughs or layoffs impacting about 2,800 contract workers. Other high-risk sites facing work delays are the Oak Ridge Reservation in Tennessee, Savannah River Site in South Carolina and the Idaho National Laboratory. EDUCATION Some 70,000 students enrolled in pre-kindergarten Head Start would be cut from the program and 14,000 teachers would lose their jobs. For students with special needs, the cuts would eliminate some 7,200 teachers and aides. The Education Department is warning that the cuts will impact up to 29 million student loan borrowers and that some lenders may have to lay off staff or even close. Some of the 15 million college students who receive grants or work-study assignments at some 6,000 colleges would also see changes. The 77-member Student Aid Alliance â¿¿ a coalition of universities and college professionals â¿¿ says the cost to a student could be as much as $876 annually in new fees, fewer work-study hours and reduced grants for students receiving federal aid. CONGRESS Congressional trips overseas likely will take a hit. House Speaker John Boehner, R-Ohio, told fellow Republicans that he's suspending the use of military aircraft for official trips by House members. Lawmakers typically travel on military planes for fact-finding trips to Afghanistan or Pakistan, or other congressional excursions abroad. TAXES The Internal Revenue Service says tax refunds shouldn't be delayed because it won't furlough workers until summer. But other IRS services will be affected. Millions of taxpayers may not be able get responses from IRS call centers and taxpayer assistance centers. The cuts would delay IRS responses to taxpayer letters and reduce the number of tax returns reviewed, impacting the agency's ability to detect and prevent fraud. The IRS says this could result in billions of dollars in lost revenue to the government.
