Are you sure? According to ARIN staff, current implementation of policy
is that all requests are approved since there are no defined criteria
that would allow them to deny any. So far, nobody's shown interest in
plugging that hole in the policy because it'd be a major step forward if
IPv6 were popular enough for anyone to bother wasting it...

I believe Stephen is thinking of initial allocation policy - because a
subsequent allocation policy in the ARIN region exists: (and it's been
modified atleast once in the last few years)
Justification to obtain another netblock is .94 HD-Ratio in the
current allocation
Endusers (minimum allocation is a /48)
For a /48 that's about 72% utilization or 184 /56's assigned/used
ISP's (minimum allocation is a /32)
For a /32 that's about 37% utilization or 6,183,533 /56's assigned
ARIN provides a handy chart:
