If you are paid through the fall semester, you must clean out your locker during finals week of the fall semester. If you are paid for fall and spring, you have to clean out your locker during finals week of the spring semester, but not during winter break between semesters. If you are paid through summer, you have to clean out your locker two weeks before school starts. Exception: If you renew your locker, you must clean your locker out by the end of the semester that you paid through, unless of course, it is through summer, and then you will need to clean out two weeks before the fall semester starts.
Denver has made strides in cleaning it's air but inversions still occur and trap all the crap we burn in the lower atmosphere. A big part of the brown cloud was particulate from sand spread on streets during the winter, that combined with car and truck pollution made for really bad air. Being a Trump support you likely cheer Trump's war on the EPA. Without action by the EPA Denver's air would be far dirtier than it is today. I hope the EPA works with Denver continue to work towards less pollution, especially ozone, which the Denver area is currently violating standards.
