The PRA only applies to collections directed at 10 or more respondents, but with one important exception. Any information requirement in a "rule of general applicability" is presumed to affect or potentially affect at least 10 respondents, even if MSHA expects there to be fewer respondents. A rule should be considered to have general applicability unless you can demonstrate that it would be impossible for there ever to be 10 respondents.
Can one conduct a data collection without PRA approval if fewer than 10 respondents are involved?
