Abstract:
This memorandum transmits additional interpretive nonbinding guidance
on the handling and transportation of PM2.5 filter cassettes upon
completion of sampling. The guidance creates a bridge between: 1)
the 10 day requirement for filter weighing if the sample is transported
at 25 degrees C, and 2) the 30 day requirement if the sample is transported
at 4 degrees C. |
