Hmm,
my_limit_date DATE:= trunc(sysdate) - 6; -- !!! only 6
erh.arrival_dt < my_limit_date

(trunc(sysdate) - trunc(erh.arrival_dt)) >= 7
becomes
- trunc(erh.arrival_dt) >= 7 - trunc(sysdate)
becomes by negating
trunc(erh.arrival_dt) <= trunc(sysdate) - 7
becomes
erh.arrival_dt <= trunc(sysdate) - 7 + 0.9

Cherie,
Change the clause as follows
orig ==> (trunc(sysdate) - trunc(erh.arrival_dt)) >= 7 AND
new ==> erh.arrival_dt <= sysdate - 7 AND
Hope this helps!

Wouldn't this introduce a time-of-day dependency on the result?
Instead, how about:
(trunc(sysdate) - erh.arrival_dt)) > 6 AND
(ie. strictly greater than six days ago)
