and Repair programs for a specified period after retrofit
            –          Use of electronic tolling to restrict or charge non-retrofitted vehicles for access to specified areas in the urban environment
            –          Rebates or other subsidies on approved retrofit technology
            –          Bundling fuel-efficient technologies with emission control devices. Under this approach, successfully implemented in the USA, ongoing fuels savings can mitigate the retrofit device cost. Devices are available that reduce fuel use in trucks by reducing air drag (aerodynamic improvement devices), rolling resistance of tyres or improving drive train operations. By purchasing and installing a kit containing fuel efficiency devices and an exhaust retrofit device, truck operators can save money through reduced fuel use to reduce the cost of the exhaust retrofit.

3.2   Technology Assessment

 Retrofit devices need to be objectively assessed for their:

           * capacity to deliver emission reductions

           * applicability to particular vehicles/engines

           * durability and reliability.

            1. Performance Requirements

 Demonstration of compliance with performance requirements is a pre-requisite for acceptance of particular appliances in retrofit programs. This section is based on DOCs, DPFs and PFTs but could be adapted for other aftertreatment devices which comply with the requirements.

 To be considered for use in a retrofit program, a DOC, DPF or PFT should meet the following requirements:

 1. The DOC/DPF/PFT is:

 (a) approved by the US EPA under the Urban Bus Rebuild/Retrofit Program;

 (b) approved under the London Bus Retrofit Program; or

 (c) emission tested under the relevant Composite Urban Emissions Drive Cycle, UN ECE Type I emission test under ECE R83/04 or later (or equivalent EC Directive), the UN ECE 13 mode steady state test under ECE R49/02 or later (or equivalent EC Directive), or the US CFR 40 Part 86 EPA Federal Test Procedure.

 2. When tested in accordance with one of the options under (1c):
The device shall achieve particulate matters reductions to any one of the three classification levels, with no increase in emissions of other pollutants in the vehicle exhaust.

Pollutant  Classification Level                Reduction
           Level 1 (DOCs)                      25%
PM         Level 2 Partial filter traps (PFT)  50%
           Level 3 DPF                         85%

    (These classification levels 1, 2 & 3 align with US Californian Air Resources Board (CARB) classification levels.)

 3. The DOC/DPF/PFT is demonstrated (by means of specific testing or engineering analysis) to deliver the percentage reductions in (2) for the size and type of engines used in the target vehicles.

 4. The DOC/DPF/PFT is demonstrated to deliver the reductions in (2) on diesel fuel with sulfur levels typical of the fuel used by the target vehicles in normal use.

 5. The DOC is demonstrated (by means of an acceptable durability test or in-service testing) to remain effective over the life of the vehicle. The DPF
