2. Use of the vehicle is consistent with the condit ions of the Executive Order for the VDECS. 3. The VDECS is installed in a verified configurati on.A-31 4. The engine to be retrofit meets engine manufactu rer’s specifications for installation of the VDECS.

5. The VDECS label will be visible after installati on. (B) VDECS Maintenance . If a fleet owner installs a VDECS to meet the requirements of section 2025(e), the VDECS must rem ain installed until the VDECS fails or is damaged or is replaced with a similar or higher level VDECS. Requirements for VDECS failure or damage ar e in section 2025(o)(9). The owner of a vehicle retrofi t with a VDECS must ensure that the VDECS and engine are properly maint ained as recommended by the respective manufacturers. (2) Failure or Damage of a VDECS. In the event of a failure or damage of a diesel emi ssion control strategy, the following conditions apply: (A) Failure or Damage During the Warranty Period. If a VDECS fails or is damaged within its warranty period, and the VDECS m anufacturer or authorized dealer determines that it cannot be repa ired, the owner must replace the VDECS with the same level or higher lev el VDECS for the vehicle within 90 days of the failure. (B) Failure or Damage Outside of Warranty Period. If a VDECS fails or is damaged outside of its warranty period and cannot b e repaired, and if the fleet could not meet an applicable target for the m ost recent compliance date without the failed VDECS, then within 90 days of the failure, the owner must replace the failed VDECS with the highes t level VDECS available for the engine at time of failure. (3) Fuel-Based Strategy VDECS.

(A) If a fleet owner determines that the highest le vel VDECS for a large percentage of the fleet would be a level 2 fuel ver ified as a diesel emission control strategy, and implementation of this VDECS would require installation of a dedicated storage tank, then the owner shall request prior approval from the Executive Officer to allow use of the level 2 fuel-based strategy across its fleet. (B) Waiver for Discontinuation of Fuel Verified as a Diesel Emission Control Strategy. If a fleet owner has relied upon a fuel verified as a diesel emission control strategy to meet an applicable per formance requirement and has to discontinue use of the fuel due to circu mstances beyond the fleet owner’s control, the fleet owner shall apply to the Executive Officer no later than 30 days after discontinuing use of th e fuel for a compliance waiver of up to two years to provide the fleet owne r time to return to compliance with the applicable performance requirem ents. The Executive Officer shall respond to the request within 30 days and grant the request upon finding that the application is complete, outl ines the compliance strategy to be used, and that all reporting require ments have been met.A-32

(4) Use of Experimental Diesel Emission Control Strateg ies

.

(A) If a fleet owner wishes to use an experimental or non-verified diesel emission control strategy, the owner must first obt ain approval from the Executive Officer for a compliance extension. To o btain approval, the owner must demonstrate either that (1) a VDECS is n ot available or not feasible for their vehicle or application, or (2) t hat use of the non-verified strategy is needed to generate data to support veri fication of the strategy. 1. The application must include emissions data and a detailed description of the control technology demonstrating the experimental control strategy achieves at least a level 2 diesel PM emission reduction. 2. The Executive will treat the strategy as follows : a. As a level 2 VDECS if the application demonstrat es that the strategy achieves at least 50 percent reduction in diesel PM. b. As a level 3 VDECS if the application demonstrat es that the strategy achieves at least 85 percent reductions in diesel PM. 3.If the application demonstrates that the strategy achieves a NOx reduction of over 15 percent, the NOx reduction wil l be counted. (B) Upon approval by the Executive Officer, each ve hicle engine retrofit with the experimental strategy will be allowed to operat e for a specified time period necessary to make a determination that the e xperimental strategy can achieve the projected emissions reductions. Th e vehicle equipped with the experimental strategy will be considered t o be in compliance under section 2025(f), (g), or (h) during the speci fied time period. The fleet owner shall keep documentation of this use in records as specified by the Executive Officer. (C) The fleet owner must bring the fleet into compl iance under section 2025(f), (g), and (h) prior to the expiration of the experim ental diesel emission control strategy extension.
