Keep in mind that non-sterile facilities are just what they say they
are --NON-STERILE-- and most environmental monitoring is only a "snapshot"
of the microbial bioburden at the time of sampling.  Here are some
references for you and the rest of the group:

PhRMA Environmental Monitoring Working Group.  "Microbiological Monitoring
of Environmental Conditions for Nonsterile Pharmaceutical Manufacturing",
Pharmaceutical Technology, March, pp. 58, 60, 64, 66, 68, 70, 72,74, 1997.

Dell, L.A. "Aspects of Microbiological Monitoring for Nonsterile and Sterile
Manufacturing Environments", Pharmaceutical Technology, August, pp. 47-51,

Plant Using Standard, Elective and Selective Culture Media", Pharmaceutical
Technology, November, pp. 93-98, 100, 1980.
