Cortney,
Per your request, attached is the results from the query that shows the number 
of SI engines per facility from the RICE Population Database.
The average number per facility is actually 3.7.  However, since it's probably 
not possible to test more than two engines in a single day, we used an 
estimate of two per test.
(See attached file: Number of non-emergency SI engines per facility from RICE 
Population Database 7-29-30.xls)
