VOLUME 114, ISSUE 92 UNC's cogeneration plant The cogeneration plant, which opened in 1940, is responsible for providing energy to campus. The plant distributes electricity using coal and progressive techniques and is the kingpin of a network of campus energy facilities that keep UNC running. Leaders constantly are evaluating ways to reduce cost and improve efficiency. I Coal, the principal fuel for the plant, is the most economical and available fuel. V. The plant receives coal by railway car mostly from Kentucky and West Virginia "Wr ~ three times a week.

Board cements cap on tuition Student leaders lament lack of input in process BY ERIC JOHNSON SENIOR WRITER The UNC-system adopted Friday a detailed set of tuition guidelines likely to have a far-reaching impact on students and their parents during the next four years. The plan, approved unanimously by the system Board of Governors, puts a 6.5 per cent per year cap on in-state undergraduate tuition hikes. INSIDE Student leaders and officials have unique relationship PAGE 6 of a process meant to incorporate student opinion in university decisions. Derek Pantiel, president of the system Association of Student Governments, summed up his frustration before last week’s vote. “This is my first tuition policy task force meeting and my last,” he told a gathering of student leaders. “I wish I had been in on these meetings last year.” Representing students in system-level policy discussions is a core responsibility of the ASG, and former President Zack Wynne was involved in the earliest stages of the nPF tuition process. “We rely on the student representative to the Board of Governors,” said Rob Nelson, the system’s vice president for finance. “They were given a place on the tuition task force.” But a combination of leadership transi tions and bad timing caused the student voice in that critical debate to taper off. System President Erskine Bowles put the tuition task force on hold shortly after taking office in January, saying he wanted time to study the issue and weigh in. In April, while the task force remained dormant, Pantiel was elected president of the ASG. “The (tuition) discussion had dropped off long before Derek came along,” Wynne said. “It just kind of stopped, and they never put any sort of timeline on it.” Pantiel and other ASG officials com plained that they were given little informa tion about the task force, which left them scrambling for a response when Bowles brought forward his plan two weeks ago. But Wynne said there simply wasn’t much information to share. “We didn’t sit there and go over it because there was nothing to go over,” he said, noting that Bowles essentially took control of the process when he took office. Still, some information about the propos al was available long before Bowles officially unveiled his plan, and student leaders were told about it.
