the Measure; and

 (3) the need, if any, for amending the Measure (in accordance with the Act), including:

           * whether any changes should be made to Schedule A; and

           * whether any changes should be made to improve the effectiveness of the Measure in achieving the Goal and Desired Environmental Outcome set out within it.

 Schedule A  Guidelines for the management of in-service diesel emissions

The following Guidelines provide guidance on the possible means for achieving the Goal (Clause 10 of the Measure) and Desired Environmental Outcome (Clause 11 of the Measure) for the management of in-service diesel emissions.

Title of Guideline
Schedule A (1)

Guideline on smoky vehicle programs
Schedule A (2)

Guideline on diesel vehicle emission testing and repair programs
Schedule A (3)

Guideline on audited maintenance programs for diesel vehicles
Schedule A (4)

Guideline on diesel vehicle retrofit programs

 Schedule A (1) Guideline on smoky vehicle programs

1.       Objective

 To improve the emissions performance of in-service diesel vehicles by:

           * providing a means of detecting vehicles emitting excess smoke;

           * requiring the repair of vehicles emitting excessive smoke; and/or

           * encouraging vehicle owners to regularly tune and maintain their vehicles.

2.       Scope

 Excessive smoke emissions from diesel vehicles are visually offensive, odorous and potentially a risk to public health. Australian Design Rule 30/00, which was introduced in 1976, required all new vehicles to meet smoke opacity standards.  However, deterioration of engine components frequently leads to an increase in smoke emissions, which can be rectified through service or repair.

 A smoky vehicle program is intended to provide a means of detecting vehicles that have deteriorated to a point where excessive emissions can be visually observed.  Smoky vehicle programs may require the owner to repair the vehicle or may simply encourage owners to make repairs to reduce smoke.  Some programs combine both approaches.

 Jurisdictions that currently operate smoky vehicle programs apply the "ten second smoke rule" to identify vehicles with excess smoke emissions.  That is, smoky vehicles are those detected emitting smoke continuously for a period of ten seconds or more.

 The correlation between smoke and other pollutants is uncertain. Therefore a smoky vehicle program which uses the ten second smoke rule cannot ensure detection of vehicles with excess emissions of NOx, hydrocarbons (HC), carbon monoxide (CO) or particles.  Other guidelines within this Measure describe emission management approaches which are specifically designed to detect and rectify excessive emissions of these pollutants.  Jurisdictions should ensure that strategies are in place to detect the range of pollutants. Jurisdictions should also monitor developments in science and technology and seek expert advice where necessary.

 Together with the use of the ten second smoke rule by authorised personnel, smoky vehicle programs normally make provision
