In
addition,
all
Agency

EPA)

and

estimates
should
be
removed
from

In
the
August
16,
2001,
Microbial
ICR,
Agency
burden
was
estimated
for
the
Lab
QA
Program
only.
Since
the

will
be
removed
from
the
Microbial
ICR,
no
rule­
specific
Agency
burden
or
cost
will
be
associated
with
the
Microbial

EPA
burden
and
costs
for

for
all
EPA

are
accounted
for
under
the
