Sorry, at the moment this is the only area open for late night study.
Might I suggest you remind those around you that your purpose for being there is to study and ask that they keep the noise down a bit? Why not suggest they use headphones? We do require this in Regulations Governing Personal Behavior( http://library.mcmaster.ca/policies/behaviour). We will see if we can raise awareness on this specific issue through some of our other news devices.
Also, as far as the area being dirty, additional custodial services have been arranged to make sure this area is kept cleaner in the evenings and on weekends.
