National Environment Protection Measure (Measure)
means a Measure made under section 14(1) of the Commonwealth Act and the equivalent provisions of the corresponding Acts of participating States and Territories.
Participating jurisdiction
means the Commonwealth, a participating State or a participating Territory.
Participating State
means a State:
(a) that is a party to the Agreement; and
(b) in which an Act that corresponds to the Commonwealth Act is in force in accordance with the Agreement.
Participating Territory
means a Territory:
(a) that is a party to the Agreement; and
(b) in which an Act that corresponds to the Commonwealth Act is in force in accordance with the Agreement.
This Measure is made pursuant to section 14(1)(g), 14(2)(a) and 14(2)(b) of the Commonwealth Act and the equivalent provisions of corresponding Acts in participating States and Territories.
This Measure forms part of an integrated suite of approaches being implemented by participating jurisdictions to manage emissions from diesel vehicles. Four broad approaches are available to manage vehicle emissions. These are to
It is the purpose of this Measure to provide a framework for the management of in-service emissions from diesel vehicles that complements and protects the emissions improvements obtained from existing regimes. New vehicle emission standards and fuel quality standards are specified in Commonwealth legislation. Strategies to reduce vehicle use are beyond the scope of this Measure.
Diesel vehicles make a disproportionately high contribution to NOx and particle air pollution from the transport sector. The diesel vehicle proportion of the transport fleet is increasing and this trend is expected to continue. Emissions from diesel vehicles have the potential to cause adverse health effects and detract from urban amenity.
The National Environment Protection (Ambient Air Quality) Measure 1998 provides national air quality standards for six criteria pollutants. The criteria pollutants include PM10 and nitrogen dioxide, of which diesel vehicles are a significant emission source.
Jurisdictions should assess the need for the management of emissions from in-service diesel vehicles as a strategic option for:
Vehicle operators, both owners and drivers, have responsibilities that come with approval to use the road network. They must ensure that their vehicles continue to meet all applicable standards.
Governments, as regulators of on-road vehicles, need to have compliance programs in place that can ensure that operators are meeting these responsibilities. To ensure equivalent protection for the community, compliance systems should implement and achieve nationally consistent standards.
Community expectations and the impact of non-compliance need to be taken into account when assessing the adequacy of current levels of compliance.
Schedule A of this Measure contains Guidelines to assist jurisdictions to develop programs for reducing emissions from in-service diesel vehicles, in order to achieve compliance with appropriate in-service emissions standards.
Compliance programs may incorporate a combination of the approaches in the Guidelines. Emission management approaches other than those in the guidelines may also be implemented.
Compliance programs
A compliance program may include any or all of the following components:
Communications program
Compliance programs will each require a communications program to inform the target audience/s of their responsibilities, the benefits that may be gained from compliance and the implications, for the operator and the community, of non-compliance.
Developing compliance programs
The factors to be considered in developing a compliance program include:
– the availability and quality of information about operator responsibilities;
– the ‘reasonableness’ of operator responsibilities;
– equity issues; and
– a system’s credibility, efficiency, effectiveness, cost and convenience.
Compliance program effectiveness
The effectiveness of programs will be assessed on their ability to achieve the Goal and Desired Environmental Outcome specified in Clause 10 and Clause 11 respectively.
The scope of this Measure is to provide guidelines for developing programs to minimise the deterioration in exhaust emissions performance, or improve exhaust emissions performance, from diesel vehicles while they are in service.
The Goal of this Measure is to reduce exhaust emissions from diesel vehicles, by facilitating compliance with in-service emissions standards for diesel vehicles.
The desired environmental outcome of this Measure is to reduce pollution from in-service diesel vehicles.
The assessment of in-service emission performance of the diesel fleet requires a means of objectively assessing the emission performance of vehicles against a benchmark for acceptable emission levels.
Participating jurisdictions will use the in-service vehicle emission standards and test determined by the Australian Transport Council or successor body as the benchmark against which to assess the emission performance of diesel vehicles.
The emission standards have been developed for determining pass/fail limits for the Test and Repair Program and for comparative purposes for the Audited Maintenance Program. However, they can also be used as a benchmark for assessing the effectiveness of the other three strategies.
This Measure recognises the different degrees of impact of diesel exhaust emissions between and within participating jurisdictions. This Measure requires participating jurisdictions to assess the need to manage emissions from in-service diesel vehicles, taking into consideration the following criteria:
Where this assessment demonstrates a need to manage in-service diesel emissions, participating jurisdictions may use the Guidelines in Schedule A to develop compliance programs that are appropriate for their particular circumstances.
Vehicles crossing jurisdictional borders will be subject to the provisions of compliance programs implemented within the jurisdiction to which the vehicle has travelled.
Schedule A provides Guidelines on four approaches for improving the maintenance and operation of in-service diesel vehicles to reduce their emissions and hence their impact on the health and amenity of the community.
Schedule A(1): Guideline on Smoky Vehicle Programs
Schedule A(2): Guideline on 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
(1) It is intended that each participating jurisdiction submit a report to the Council on the following matters:
(a) Assessment of the need to take action to manage emissions from the in-service diesel fleet, utilising the criteria specified in clause 13.
(b) Description of actions taken.
A brief description of all programs implemented during the reporting year to manage emissions from in-service diesel vehicles, including any programs implemented that are not covered by the guidelines in Schedule A of this Measure.
This description should take account of:
– the scope of action required to achieve the Goal and Desired Environmental Outcome specified in this Measure; and
– any action taken and progress made to reduce emissions from in-service diesel vehicles prior to the commencement of this Measure (relevant in the first year of reporting).
(c) Assessment of the effectiveness of any actions taken.
Participating jurisdictions must assess their progress in reducing emissions from in-service diesel vehicles identified as significant contributors to air quality problems. This assessment should include:
– an estimation of any change in the proportion of diesel vehicles out of compliance with in-service emissions standards; and
– an estimation of the reduction in diesel vehicle emissions to ambient air.
(2) Participating jurisdictions must submit a report under subclause (1) to the Council by 30 September next following each reporting year. The first reporting year will end 30 June 2002.
(3) In this clause ‘reporting year’ means a year ending 30 June.
This Measure will be subject to review five years from the date of commencement, or within any lesser period determined by the Council, which will consider:
(1) the effectiveness of the Measure in achieving the Goal and Desired Environmental Outcome set out within it;
(2) the resources available for implementing the Measure; and
(3) the need, if any, for amending the Measure (in accordance with the Act), including:
