through
a
variety
of
programs
and
activities:
Emissions Testing Programs
Other Programs and Services
The
Automobile
Inspection
and
Readjustment
(AIR)
Program's
purpose
is
to
reduce
motor
vehicle
related
pollution
through
the
inspection
and
emissions-related
repair
of
gasoline
powered
motor
vehicles.
Emissions
testing
of
gas
and
diesel
powered
vehicles
is
required
when
registering,
renewing
registrations,
or
selling
vehicles
within
the
program
areas
in
nine
counties
along
Colorado's
Front
Range.
The
"enhanced
program"
consists
of
the
counties
of
Boulder,
Broomfield,
Denver,
Douglas
and
Jefferson
as
the
area
west
of
Kiowa
Creek
in
Adams
and
Arapahoe
counties.
The
"basic
program"
area
consists
of
parts
of
the
counties
of
Larimer,
Weld
and
El
Paso.
The
new
RapidScreen
program
in
the
Denver
area
and
northern
Colorado
provides
an
opportunity
for
vehicles
to
forego
testing
if
they
are
found
to
meet
emissions
standards
after
driving
by a
roadside
monitor.
Denver
Metro
Area
--
Enhanced
Vehicle
Emissions
Test
1982
and
Newer
Vehicles:
An
enhanced
test
is
required
for
gasoline
powered
passenger
cars
and
light
trucks
1982
and
newer
in
the
seven-county
Denver
metro
area,
which
includes
the
counties
of
Broomfield,
Denver,
Jefferson,
Boulder,
Douglas,
and
western
Arapahoe
and
Adams
counties
(west
of
Kiowa
Creek).
New
cars
are
exempt
from
testing
to
the
original
owner
for
four
years.
The
enhanced
inspection
is
performed
at
any
one
of
14
inspection
stations
operated
by
AirCare
Colorado.
The
inspection
utilizes
a
dynamometer
which
simulates
actual
driving
conditions.
The
test
is
good
for
two
years.
Motorists
are
alerted
to
the
need
for
a
test
by a
notice
on
their
registration
renewal
forms.
Older
than
1982:
A
basic
two-speed
idle
test
is
required
each
year
for
vehicles
older
than
1982
and
heavy
trucks
in
the
six-county
Denver
metro
area.
The
basic
test
can
be
performed
at
Air
Care
Colorado
facilities,
or
at
an
independent,
licensed
test
station.
North Front Range -- Enhanced Vehicle Emissions Test
The Enhanced Vehicle Emissions test expanded from the Denver
area to parts of Larimer and Weld Counties in November of 2010 to control ground-level ozone. The Air Pollution Control Division
made the following presentation during the public hearing that provides
the regulatory and scientific basis for expanding the program to the north
Front Range.
El
Paso,
Larimer
and
Weld
Counties
-- Basic Program Discontinued
The basic
two-speed
idle
test emissions program in
El
Paso,
Larimer
and
Weld counties was discontinued January 1, 2007 based on long-term
compliance with the carbon monoxide standards.
Program
Administration
The
Automobile
Inspection
and
Readjustment
Program
is
administered
jointly
by
the
State
Air Pollution
Control
Division
and
the
Colorado
Department
of
Revenue.
The
state
air
division certifies
the
program,
including
testing
procedures
and
equipment.
It
works
with
the
Air
Quality Control
Commission,
the
Regional
Air
Quality
Council,
the
state
General
Assembly,
local governments,
the
U.S.
Environmental
Protection
Agency,
and
others
in
assessing
the effectiveness
of
the
program
and
in
determining
program
modifications.
The
Department
of
Revenue
administers
the
day-to-day
operations
including
licensing
of inspectors
and
test
facilities,
conducting
field
audits,
investigating
complaints,
processing
waivers, collecting
revenues,
and
working
with
county
governments
that

Roadside Emissions Testing
To
reduce
the
number
of
vehicles
requiring
a
traditional
emissions
inspection,
a
RapidScreen
Program
has
been
established
for
northern
Colorado
and
the
Denver
area. Clean
vehicles
that
pass
a
drive-by
roadside
test
can
forego
a
trip
to
the
emissions
inspection station if they receive a notification in the mail saying they
passed RapidScreen.
The
RapidScreen
Program
utilizes
remote
sensing
to
measure
emissions
as
vehicles
drive
past
roadside
monitors.
The
monitors
measure
emissions
and
record
license
plate
numbers.

by
means
of
two
diesel
inspection
and
maintenance
programs
–
one
for
fleets
of
nine
or
more
heavy-duty
vehicles,
and
another
for
smaller
fleets
and
privately-owned
vehicles.
Large
Fleets
Owners
and
operators
of
larger
diesel
fleets
take
part
in a
Diesel
Fleet
Self-Certification
Program.
The
program
requires
fleet
owners
and
operators
to
self-inspect
and
certify
their
vehicles
annually
to
maintain
compliance
with
state
smoke
opacity
standards.
Fleets
subject
to
the
self-inspection
and
certification
are
those
within
the
Automobile
Inspection
and
Readjustment
Program
area
with
nine
or
more
diesel
vehicles
of
more
than
14,000
pounds
empty
weight.
New
heavy
duty
diesel
vehicles
have
a
four-year
exemption
from
testing.
A clean diesel school bus retrofit program provides no-cost
diesel emission controls for school districts in Colorado.
Small
Fleets
and
Individuals
Small
fleets
and
privately-owned
diesel
vehicles
take
part
in
the

program
is
for
all
light-duty
diesel
vehicles
as
well
as
heavy-duty
diesel
vehicles
not
subject
to
the
large
fleet
self-certification
program.
The
Diesel
Opacity
Inspection
Program
requires
that
eligible
vehicles
be
inspected
on
an
annual
basis
by
private,
state-licensed
diesel
inspection
stations.
New
light-duty
diesel
vehicles
are
exempt
from
testing
for four years.
The
program
applies
only
to
the
Automobile
Inspection
and
Readjustment
Program
area
and
utilizes
a
loaded

(CARS)
In
addition
to
Small
Business
Technical
Assistance,
the
Consumer
Assistance
for
Repairs
and
Service
(CARS)
Program
was
created.
The
goal
of
CARS
is
to
achieve
greater
emissions
reductions
from
vehicles
that
fail
emissions
tests.
CARS
accomplishes
this
by
providing
motorists
and
repair
facilities
with
current
and
accurate
information
on
the
emissions
repair
process;
by
investigating
consumer
issues
and
problems
within
the
inspection
and
repair
process;
by
developing
solutions
to
both
inspection
and
repair
problems;
and
by
increasing
the
public's
understanding
of
the
inspection
and
maintenance
process
and
its
relationship
to
better
air
quality.

Colorado’s
smoking
vehicle
hotline
gives
motorists
and
others
the
ability
to
report
smoking
vehicles
to
the
state
Air
Pollution
Control
Division
through
a
telephone
hotline
(303-692-3211)
or
by
e-mail.
The
state
air
division
then
provides
owners
of
smoking
vehicles
with
information
that
will
encourage
them
to
voluntarily
make
needed
repairs.
Repairs
to
smoking
vehicles
are
required
if a
vehicle
fails
a
mandatory
emissions
test
because
of a
visible
smoke
problem.
The
cause
of
such
smoke
must
be
corrected
before
the
required
emissions
sticker
can
be
issued.
Also,
a
police
officer
may
stop
a
smoking
vehicle,
issue
a
ticket
and
order
the
owner
to
make
repairs.
Colorado
law
provides
for
a
$25
fine
for
the
first
violation
of
the
smoking
vehicle
law.
The
fine
for
subsequent
violations
is
$100
(C.R.S.
42-4-412,
413).
Some
local
municipalities
have
additional
ordinances
and
fines
for
operating
a
smoking
vehicle.
