Cal. Code Regs. tit. 13, § 2702
(b) Preliminary Verification Application. Before formally submitting a final application for the verification of a diesel emission control strategy, the applicant must submit a preliminary verification application. The Executive Officer reserves the right to require that an applicant's preliminary application be submitted with a fully-functional sample of the market-ready diesel emission control strategy that is identical in all material respects to the product that will be sold upon receiving verification. If such a request is made by the Executive Officer, the applicant must submit the market-ready diesel emission control strategy within 30 calendar days or the preliminary application will be terminated. The Executive Officer may, for good cause, grant an extension of time, not to exceed fifteen days (15). The submitted diesel emission control strategy must be identical in all respects to any products used to support the verification activity and must come with all parts including, but not limited to, the aftertreatment components, sensors, electronic control system programmed with all control logic and algorithms, and the backpressure monitor as well as a complete parts list. Changes during the verification process to any part of the diesel emission control strategy including, but not limited to, control logic and algorithms, functionality, materials, catalyst loadings and formulation, hardware, etc., may require the applicant to begin the verification process anew, at the discretion of the Executive Officer. For diesel emission control strategies that include multiple sizes of the same system or part (e.g., the diesel particulate filter), the Executive Officer will specify which size must be submitted. The Executive Officer shall return, at the applicant's expense, the market-ready diesel emission control strategy after the request for verification is either granted, denied, or withdrawn. The Executive Officer shall use the information in the preliminary verification application to help determine whether the strategy relies on sound principles of science and engineering to control emissions, the need for additional analyses, and the appropriateness of allowing alternatives to the prescribed requirements. The preliminary verification application must follow the format shown in section 2702(d) and at a minimum provide the information required in sections 1. through 5., and section 8.A.5. In addition, the preliminary verification application must include the following information:
(2) Description of the diesel emission control strategy's principles of operation. A schematic depicting operation must be included. It is the responsibility of the applicant to demonstrate that its product relies on sound principles of science and engineering to achieve emission reductions.

(e) Preliminary Verification Application Review Process. A preliminary application for verification is reviewed as follows:
(1) Review for Completeness. Within 30 days of receipt of the preliminary application, the Executive Officer shall notify the applicant indicating whether the application is complete. If the preliminary application is not complete the Executive Officer shall request any missing information from the applicant.
(2) Engineering and Compliance Review. After determining that the preliminary application is complete, the Executive Officer shall conduct a technical review of the preliminary application to determine whether the preliminary application is adequate to support development of a test plan approval letter. If the preliminary application is not adequate to support development of a test plan approval letter, the Executive Officer shall request additional information from the applicant.
(f) Final Verification Application Review Process. A final application for verification is reviewed as follows:
(2) Review for Completeness. Following receipt of the final application, the Executive Officer shall notify the applicant indicating whether the final application is complete. If the final application is not complete the Executive Officer shall request any missing information from the applicant.
(3) Test Results and Compliance Review. Within 60 days of determining that the final application is complete, the Executive Officer shall determine whether the diesel emission control strategy merits verification and shall classify it as shown in Table 1:
Table 1. Verification Classifications for Diesel Emission Control Strategies
Pollutant

Not verified Level 0* (see note below)
≥ 25%
Level 1 Level 1 Plus**
PM
≥ 50%
Level 2 Level 2 Plus**
≥ 85%,
Level 3 Level 3 Plus**
or ≤ 0.01 g/bhp-hr
< 25%

Mark 1
≥ 40%
Mark 2
≥ 55%
Mark 3
≥ 70%
Mark 4
≥ 85%
Mark 5
* A diesel emission control strategy that reduces emissions of PM by less than 25 percent may be verified as a Level 0 strategy if it reduces emissions of NOx by at least 25 percent and meets the other criteria in section 2700.
** The diesel emission control strategy complies with the 20 percent NO2 limit before January 1, 2009 (and after January 1, 2007).
The Executive Officer shall notify the applicant of the decision in writing and specify the verification level for the diesel emission control strategy and identify any terms and conditions that are necessary to support the verification.
(j) Design Modifications. If an applicant modifies the design of a diesel emission control strategy during the review process, the Executive Officer will terminate the application. The applicant must re-submit an application per section 2702 (e)-(f) that includes details of the new design in order for the diesel emission control strategy to be considered for verification, a conditional verification, or a conditional extension. Re-submission must follow the requirements of section 2702(g). If an applicant modifies the design of a diesel emission control strategy that has already been verified by the Executive Officer, the modified version must be evaluated under this Procedure. The applicant must provide a detailed description of the design modification along with an explanation of how the modification will change the operation and performance of the diesel emission control strategy. To support its claims, the applicant must submit additional test data, engineering justification and analysis, or any other information deemed necessary by the Executive Officer to address the differences between the modified and original designs, to ensure that the verified emissions reductions are maintained, and to ensure that emissions of any pollutants remain compliant with the requirements per section 2706. Processing time periods follow section 2702 (e)-(f) above. A design modification includes, but is not limited to:
(k) Verification Transfers. If an applicant wishes to sell, lease, or supply another manufacturer's previously verified diesel emission control strategy, the applicant must do the following:
