Requirements for VDECS failure or damage ar e in section 2025(q)(2). The owner of a vehicle retrofi tted 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 ofthe level 2 fuel-based strategy across its fleet.35 (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 req uirement and has to discontinue use of the fuel due to circumstances be yond the fleet owner’s control, the fleet owner shall apply to the Executi ve Officer no later than 30 days after discontinuing use of the fuel for a c ompliance waiver of up to two years to provide the fleet owner time to return to compliance with the applicable requirements. The Executive Officer sha ll respond to the request within 30 days and grant the request upon f inding that the application is complete, outlines the compliance st rategy to be used, and that all reporting requirements have been met. (4) Use of Experimental Diesel Emission Control Strategies

.

(A) If a fleet owner wishes to use an experimental or non-verified diesel emission control strategy to support the verificati on of a 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 the following: emis sions data and a detailed description of the control technology thatdemonstrates that the experimental control strategy achieves at least a level 2 diesel PM emission reduction, vehicle and engine data, and od ometer readings as described in sections 2025(r)(8), 2025(r)(9), an d 2025(r)(12)(B). 2. The Executive Officer will treat the strategy as a: a. Level 2 VDECS if the application demonstrates th at the strategy achieves at least 50 percent reduction in diesel PM

. b. Level 3 VDECS if the application demonstrates th at the strategy achieves at least 85 percent reductions in diesel P M. 3. If the application demonstrates that the strateg y 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 retrofitted with the experimental strategy will be allowed to o perate for a specified time period necessary to make a determination that the experimental strategy can achieve the projected emissions reduct ions. The vehicle equipped with the experimental strategy will be con sidered to be in compliance under section 2025(f), (g), or (h) durin g the specified time period. The fleet owner shall keep documentation o f 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), or (h) prior to the expiration of the experime ntal diesel emission control strategy extension.36

(5) VDECS That Impairs Safe Operation of Vehicle - A fleet owner may request that the Executive Officer find that a VDECS should not be considered the highest level VDECS available because (A) it cannot be safely ins talled or operated in a particular vehicle application, or (B) its use woul d make compliance with occupational safety and health requirements, or an ongoing local air district permit condition impossible.

If a VDECS manufacturer states that there is no saf e or appropriate method of mounting its VDECS on the requesting party’s vehicle, then t he VDECS will not be considered safe. In the absence of such a declaration by the VDECS manufacturer, the requesting party shall provide other documentation to support its claims.

Documentation may include published reports and oth er findings of federal, state or local government agencies, independent testing labo ratories, engine manufacturers, or other equally reliable sources. The request will o nly be approved if the requesting party has made a thorough effort to find a safe method fo r installing and operating the VDECS, including various locations for VDECS mounti ng, and use of an actively regenerated VDECS. The Executive Officer shall rev iew the documentation submitted and any other reliable information that he or she w ishes to consider and shall make his or her determination based upon the totality of the evidence. Upon finding that a VDECS cannot be installed witho ut violating the safety standards prescribed under title 8, CCR by the California Dep artment of Industrial Relations, Division of Occupational Safety and Health, or comp arable federal or state law where the vehicle operates, the Executive Officer shall i ssue a determination that there is no highest level VDECS available. The Executive Offic er shall inform the requesting party, in writing, of his or her determination, within 60 days of receipt of the request.
Parties may appeal the Executive Officer’s determin ation as described in (A) and (B) below.
