Insurance companies covering kegs for on-campus fraternities?

i understand that a majority of fraternities (and college campuses alike), outlaw kegs on campus.on our campus, we're in a transition state where we are moving towards outlawing kegs; mainly because the majority of insurance policies do not cover the fraternity if kegs are present at the party (e.g. if a drunk idiot throws a beer can and hits a girl in the head, the school is not covered). we cannot stop alcohol consumption on campus, it is bound to happen. the way our social scene works here, fraternities are the only thing keeping kids from consuming alcohol off campus (and traversing a VERY dangerous local area). not only this, but moving to cans would result in a HUGE increase in waste that SHOULD be recycled, but nonetheless is not, therefore damaging the environment in a time where going green is a large, as well as necessary, movement in america. we are therefore looking for other options. any input would be greatly apprecited
