The

limitations
are
based
on
the
specific
types
of
deicing/
anti­
icing
practices
currently
being
conducted
and
chemicals
currently
being
used
in
the
respective

In
the
event
that
deicing/
anti­
icing
practices
change
or
additional
or

chemicals
are
used,
the
permittee
shall
notify
the
Indiana
Department
of
Environmental

as
required
by
Part

of

Samples
will
be
taken
during
every
discharge
beginning
with
the
first
application
of
chemicals
during
the
deicing/

season
in
the
respective
watershed.
Upon
completion
of
deicing/
anti­

for
the
season
in
the
respective
watershed,
sampling
may
be
discontinued
after
the
propylene

is
reported
as

Refer
to
the
Schedule

Composite
samples
will
consist
of
flow­
weighted
samples
taken
at
a
maximum
interval
of
one
(
1)
hour
during
the
first
four
(
4)
hours
of
the
discharge.
The
first
sample
shall
be
taken
within
the
first
thirty
(

or
as
soon
thereafter
as
practicable,
of

Cyanide
shall
be
measured
and
reported
as
Total
Cyanide.
The
maximum
holding
time
for
cyanide
(
CN)
is
24
hours
when
sulfide
is
present
and
14
days
when
sulfide
is
absent,
according
to
40
CFR
136.3,
Table
II.
Therefore,
CN
is
to
be
monitored
by
collecting
a
representative
grab
sample
and
analyzing
it
within
24
hours.
Alternatively,
if
the
permittee
can
demonstrate
the
wastewater
contains
no
sulfide,
the
permittee
may
collect
a
composite
sample
and
analyze
it
within
14
days.

to
the
Indiana

3.
Definitions
a.
Monthly
Average
(
1)
Weight
Basis
­
The
"
monthly
average"
discharge
means
the
total
discharge
during
a
calendar
month
divided
by
the
number
of
days
in
the
month
that
the
production
or
commercial
facility
was
discharging.
Where
less
than
daily
sampling
is
required
by
this
permit,
the
monthly
average
discharge
shall
be
determined
by
the
summation
of
the
measured
daily
discharges
by
weight
divided
by
the
number
of
days
during
the
calendar
month
when
the
measurements
were
made.

(
2)
Concentration
Basis
­
The
"
monthly
average"
concentration
means
the
arithmetic
average
(
proportional
to
flow)
of
all
daily
determinations
of
concentration
made
during
a
calendar
month.
Daily
determinations
of
concentration
made
using
a
composite
sample
shall
be
the
concentration
of
the
composite
sample.
When
grab
samples
are
used,
the
daily
determination
of
concentration
shall
be
the
arithmetic
average
(
weighted
by
flow
value)
of
all
the
samples
collected
during
the
calendar
day.

b.
"
Daily
Maximum"
Discharge
(
1)
Weight
Basis
­
The
"
daily
maximum"
discharge
means
the
total
discharge
by
weight
during
any
calendar
day.

(
2)
Concentration
Basis
­
The
"
daily
maximum"
concentration
means
the
daily
determination
of
concentration
for
any
calendar
day.

c.
A
composite
sample
consists
of
flow­
weighted
samples
of
wastewater,
taken
by
the
grab
sample
method
or
by
an
automatic
sampler,
which
are
taken
at
approximately
equally
spaced
time
intervals
and
which
are
combined
prior
to
analysis.
A
composite
sample
is
obtained
by:

(
1)
recording
the
discharge
flow
rate
at
the
time
each
individual
sample
is
taken,

(
2)
adding
together
the
discharge
flow
rates
recorded
from
each
individual
sampling
time
to
formulate
the
"
total
flow"
value,

(
3)
the
discharge
flow
rate
of
each
individual
sampling
time
is
divided
by
the
total
flow
value
to
determine
its
percentage
of
the
total
flow
value,

(
4)
then
multiply
the
volume
of
the
total
composite
sample
by
each
individual
samples
percentage
to
determine
the
volume
of
that
individual
sample
which
will
be
included
in
the
total
composite
sample.

d.
Concentration­­
The
weight
of
any
given
material
present

STORM
WATER
POLLUTION
PREVENTION
PLAN
A
storm
water
pollution
prevention
plan
(
SWPPP)
will
be
developed
and
implemented
for
the
Indianapolis
International
Airport.
The
permittee
shall
ensure
that
SWPPPs
are
developed
and
implemented
for
the
common
areas
of
the
airport.
For
leased
areas
or
other
areas
of
the
airport
occupied
by
airport
tenants,
the
permittee
shall
ensure
that
the
tenants
that
are
engaged
in
industrial
activity
and
who
conduct
operations
which
result
in
"
storm
water
discharges
associated
with
industrial
activity"
develop
and
implement
SWPPPs.
The
permittee
shall
maintain
a
file
with
copies
of
all
SWPPPs
for
the
affected
airport
tenants.
For
the
purpose
of
this
permit,
tenants
engaged
in
industrial
activity
at
the
Indianapolis
International
Airport
include
airline
companies,
fixed
base
operators
and
other
parties
which
have
contracts
with
the
permittee
to
conduct
business
operations
on
airport
property
which
result
in
storm
water
discharges
associated
with
industrial
activity
as
described
in
40
CFR
122.26(
b)(
14).
SWPPPs
developed
for
areas
occupied
by
the
tenants
shall
include
the
requirements
specified
in
this
section
and
shall
be
integrated
or
congruent
with
the
SWPPP
for
the
entire
airport.
SWPPPs
shall
be
prepared
in
accordance
with
good
engineering
practices
and
shall
identify
potential
sources
of
pollution
which
may
reasonably
be
expected
to
affect
the
quality
of
storm
water
discharges
associated
with
industrial
activity
from
the
airport.
The
permittee
must
implement
the
provisions
of
the
SWPPP
required
under
this
part
and
impose
the
same
on
the
affected
tenants,
as
a

Development
of
Plan
Within
12
months
from
the
effective
date
of
the
permit,
the
permittee
is
required
to
develop
and
implement
a
Storm
Water
Pollution
Prevention
Plan
(
SWPPP)
for
the
permitted
facility.
The
plan
shall:

a.
identify
potential
sources
of
pollution
which
may
reasonably
be
expected
to
affect
the
quality
of
storm
water
discharges
associated
with
industrial
activity
from
the
facility.
Storm
water
associated
with
industrial
activity
includes,
but
is
not
limited
to,
the
discharge
from
any
conveyance
which
is
used
for
collecting
and
conveying
storm
water
and
which
is
directly
related
to
manufacturing,
processing
or
materials
storage
areas
at
an
industrial
plant
or
facility;

b.
describe
practices
to
be
used
in
reducing
the
potential
for
pollutants
to
be
exposed
to
storm
water;
and
c.
assure
compliance
with
the
terms
and
conditions
of
the
permit.

to
contribute
pollutants
to
the
storm
water
discharge
by
exposing
the
storm
water
to
industrial
activity.
Such
assessment
and
inventory
shall
consider
factors
such

drainage
points,
and
that
minimizes
the

for
spills
to
occur.
The
