Ga. Comp. R. & Regs. R. 391-3-20-.05 - Emission Standards
(1)
An inspector shall not perform a tampering inspection, an exhaust emission
test, a fuel cap verification, or an OBD system check on a vehicle which:
(a) has a missing exhaust system,
or
(b) is unsafe to
inspect.
(2) The
inspector shall not issue a Certificate of Emission Inspection indicating an
overall passing result for the emission inspection unless the inspector has
inspected the vehicle in accordance with the requirements of the Act and this
Chapter and the vehicle has passed the tampering inspection, the OBD system
check, the fuel cap verification, and the exhaust emissions test where
applicable.
(a) The vehicle shall pass the
tampering inspection if:
1. the catalytic
converter(s) has not been removed or disconnected;
2. no catalytic converter was installed by
the original equipment manufacturer as determined from the vehicle emission
control label;
3. in the case of a
vehicle which has been converted from a single exhaust system to a dual exhaust
system and a catalytic converter(s) was part of the original single exhaust
system configuration, a catalytic converter has been installed in each pipe of
the dual exhaust system;
4. in the
case of a non-conforming vehicle for which either the original vehicle or the
replacement engine was equipped with a catalytic converter(s), a catalytic
converter(s) has been installed; or
5. a catalytic converter(s) installed by the
original equipment manufacturer has been removed and replaced with another
catalytic converter(s).
(b) The vehicles shall pass the OBD system
check if:
1. the Georgia Analyzer System (GAS)
is able to communicate with the vehicle's OBD system;
2. the MIL illuminates with the ignition key
in the "on" position and the engine not running, which is known as Key On
Engine Off (KOEO);
3. the OBD
system does not command the MIL to illuminate with the ignition key in the on
position with the engine running;
4. all nonexempt OBD system monitors, as
specified in the GAS, are set to "ready";
5. the OBD system does not contain any fault
codes which command the MIL to illuminate, as specified by the vehicle
manufacturer, indicating problems with the emissions control parameters
monitored by the OBD system; and
6.
the MIL does not illuminate with the ignition key in the "on" position and the
engine running, which is known as Key On Engine Running
(KOER).
(c) The vehicle
shall pass the fuel cap verification if the vehicle's primary fuel cap and,
when equipped, one secondary fuel cap is present.
(d) The vehicle shall pass the exhaust
emission test if:
1. in the case of a vehicle
subject to a 2-speed idle test any simultaneous pair of values for hydrocarbons
and carbon monoxide, in each mode, do not exceed the exhaust levels established
in the GAS, and the combined value for carbon monoxide and carbon dioxide is
equal to or more than the minimum combined value established in the GAS;
or
2. in the case of a kit car, hot
rod, or non-conforming vehicle that has been given non-conforming status by EPD
under this Chapter, any simultaneous pair of values for hydrocarbon and carbon
monoxide, in each mode of the 2-speed idle test, do not exceed the exhaust
levels established in the GAS for 1975 model year vehicles, or for the model
year of the vehicle, and the combined value for carbon monoxide and carbon
dioxide is equal to or more than the minimum combined value established in the
GAS.
Notes
State regulations are updated quarterly; we currently have two versions available. Below is a comparison between our most recent version and the prior quarterly release. More comparison features will be added as we have more versions to compare.
