documents
the
crop­

are
key
elements
of
the
exposure

used
to
determine

II.
What
Action
is
the
Agency
Taking?

The
Agency
is
seeking
comment
on
two
documents
that
describe
how
EPA
develops
and
uses
pesticide
surface
water
modeling
scenarios
in
ecological
and
drinking
water
exposure
and
risk
assessments.
These
documents
are
entitled
``
Pesticide
Root
Zone
Model
(PRZM)
Field
and
Orchard
Crop
Scenario
Metadata''
and
``
Standard
Procedures
for
Conducting
Quality
Control
and
Quality
Assurance
for
PRZM
Field
and
Orchard
Crop
Scenarios''
and
can
be
found
at
the
following
web
addresses:

and
http://

oppefed1/
models/

qa   
qc   
documentation   
ver2

Modeling
scenarios
are
defined
as
the
set
of
characteristics
of
the
agricultural
crop
to
which
a
pesticide
may
be
applied
(e.
g.,
cotton)
and
the
field
information
on
which
the
crop
is
actually
grown
(e.
g.,
soils)
that
are
necessary
to
estimate
pesticide
transport
to
surface
water.
The
modeling
sites,
or
scenarios,
the
OPP
uses
to
estimate
environmental
concentrations
in
surface
water
are
documented
in
and
developed
through
the
use
of
these
documents.
These
documents
were
developed
to
support
the
following
activities:
OP
Cumulative
Risk
Assessment,
the
Agency's
Information
Quality
Guideline,
data
quality
guidelines
and
to
improve
environmental
assessments.
The
first
document,
``
PRZM
Field
and
Orchard
Crop
Scenario
Metadata,
''
provides
a
detailed
listing
of
the
parameters
and
associated
values
specific
to
a
crop
and
field
combination
(e.
g.,
a
cotton
field
in
Yazoo
County,
Mississippi).
OPP
evaluated
several
approaches
to
documenting
the
parameters
from
a
modeling
scenario
used
to
estimate
environmental
exposures.
This
format
is
believed
to
provide
the
most
appropriate
means
to
readily
document
and
recall
critical
information
contained
in
a
given
scenario.
Users
of
this
format,
whether
Agency
staff
or
the
public,
will
be
able
to
quickly
document
a
scenario
in
a
consistent
manner
that
meets
quality
standards
implemented
by
the
OPP.
In
addition,
users
who
retrieve
information
or
wish
to
understand
the
content
of
a
crop­
field
scenario
for
a
pesticide
assessment
will
be
assured
of
a
standardized
format
which
simplifies
review.
Information
in
this
document
reflects
the
results
of
the
second
document
``
Standard
Procedures
for
Conducting
Quality
Control
and
Quality
Assurance
for
PRZM
Field
and
Orchard
Crop
Scenarios.
''
Standard
Procedures
for
Conducting
Quality
Control
and
Quality
Assurance
for
PRZM
Field
and
Orchard
Crop
Scenarios
describes
the
set
of
procedures,
methods,
and
references
to
``
construct''
or
review
for
consistency
the
information
contained
in
a
cropfield
scenario.
The
steps
and
recommendation
described
in
this
guidance
provide
a
sound
scientific
basis
for
selecting
information
with
relevance
to
what
is
observed
in
an
actual
agricultural
field
such
as
cotton.
The
methodology
is
intended
to
give
the
regulated
community,
decision­
makers
and
the
public
confidence
that
assessments
resulting
from
the
use
of
scenarios
representing
an
agricultural
field
reflect
conditions
that
are
likely
to
occur
in
the
``
real
world.
''
Numerous
methods
and
sources
of
credible
scientific
information
are
given
in
this
document
and
are
considered
readily
available
to
the
public
through
voice
contact,
public
information
sources
(e.
g.,
public
libraries)
or
the
world
wide
web.
The
Agency
has
identified
and
described
as
best
possible
information
to
support
this
guidance
and
seeks
comments
on
what
additional
information
would
help
improve
modeling
scenarios.
