RE:
Questio
fuel
marker
Jeff,

We
recommend
the
use
of
one
of
our
pre­
blended
dye/
marker
products.
This
would
eliminate
both
the
need
for
any
additional
injectors
or
tank
blending
at
the
terminal
level.
Please
let
me
know
if
you
have
any
further
questions.

Regards,

Greg
Nowakowski

Question
on
fuel
marker
Greg,
We
are
still
seriously
considering
finalizing
fuel
marker
requirements
under
the
NR
rule
and
have
not
selected
which
marker
we
would
require
be
used.
Currently,
we
are
evaluating
comments
from
terminal
operators
that
requiring
the
addition
of
a
marker
at
the
terminal
would
force
them
to
put
in
a
new
segregated­
dedicated
additive
injection
equipment
on
each
fuel
loading
arm.

Certain
terminals
are
likely
to
handle
only
heating
oil
(
and
no
other
non­
highway
fuels).
For
these
terminals,
every
batch
of
fuel
that
would
be
required
to
contain
red
dye
would
also
be
required
to
contain
the
fuel
marker.
In
such
cases,
I
am
wondering
whether
it
would
be
possible
to
mix
the
marker
you
discussed
in
your
submission
to
the
docket
with
the
red
dye
in
the
same
storage
tank
(
at
the
proper
proportions)
and
adjust
the
injection
rate
so
that
both
products
could
be
delivered
at
their
respective
required
concentrations
through
the
same
injection
system.
This
approach
would
mean
that
there
would
be
no
new
capitol
costs
for
such
terminals.
Are
you
aware
of
any
technical
or
other
considerations
that
would
prevent
such
an
approach?

Thanks
for
your
help
in
working
through
these
issues,
