State of California AIR RESOURCES BOARD

EXECUTIVE ORDER D-796 Relating to Exemptions under Section 27156 and 38391 of the Vehicle Code

Advanced Clean Air Technologies Global LLC's 'Series 450000 Three-way Catalytic Converter"

WHEREAS, Vehicle Code (VC) Sections 27156 and 38395, and Title 13, California Code of Regulations (13 CCR) Section 2222(h), authorize the California Air Resources Board (CARB) and its Executive Officer to exempt new aftermarket catalytic converters from the prohibitions of VC Sections 27156 and 38391.

WHEREAS, Advanced Clean Air Technologies Global LLC's (ACAT) of 5339 M-66 North, Charlevoix, Michigan 49720, has applied to CARB for exemption from the prohibitions in VC Sections 27156 and 38391 to market its new aftermarket Series 450000 three-way catalytic converter (TWC) for installation on selected 2004 through 2010 model year light-duty trucks [3751-5750 lbs. LVW] (LDT2) and medium-duty vehicles (MDV) equipped with On-Board Diagnostic II (OBD II) systems as listed in Appendix D-796. The catalytic converters will be sold as a universal or direct fit system.

WHEREAS, pursuant to the authority vested in the Executive Officer by Health and Safety Code Section (HSC) 39515 and in the Chief, Emissions Compliance, Automotive Regulations and Science Division by HSC Section 39516 and Executive Order G-14-012, CARB finds that the above aftermarket catalytic converter complies with the VC Sections 27156 and 38395 and 13 CCR, Section 2222(h). Emission performance of the catalytic converter was based on durability bench-aging by Umicore Autocat USA Inc. using the CARB-modified RAT-A bench-aging cycle for 100 hours, as specified in Appendix A to the "California Evaluation Procedures for New Aftermarket Catalytic Converters" as amended on September 28, 2017 (Converter Evaluation Procedures).

WHEREAS, emissions tests were conducted at SEMA Garage Emissions Laboratory, Diamond Bar, California, using a 1) 2007 4.8L Chevrolet G2500 Express Van, test group 7GMXK06.0388 and 2) 2008 5.3L GMC Envoy Denali, test group 8GMXT06.0387 certified to the MDV category and LDT2 category Low Emission Vehicle 2 Low Emission Vehicle emission standards, showed that the vehicles met the applicable emission standards with Series 450000 TWC (2 units) installed. OBD II compatibility tests performed on the same test vehicles showed that Series 450000 TWC did not affect the vehicles' ability to perform OBD II system monitoring.

WHEREAS, evaluation of Series 450000 TWC using the procedures and criteria specified in Section (e)(5)(B) of the Converter Evaluation Procedures showed that the catalytic converter meets the requirements for proper MIL illumination demonstration. -2-

THEREFORE, IT IS HEREBY RESOLVED that ACAT's 450000 TWC is exempted from the prohibitions in VC Sections 27156 and 38391 for installation on the approved vehicle applications specified in Appendix D-796 subject to the following conditions:

1. No changes are permitted to the catalytic converter as described in the application for exemption. Any changes to the catalytic converter or any of their components, and other factors addressed in this order must be evaluated and approved by CARB prior to marketing in California.

2. Marketing of the catalytic converter using identifications other than those shown in the exemption application, and in this Executive Order, or marketing of the catalytic converter for applications other than the ones shown in this Executive Order shall be prohibited unless prior approval is obtained from CARB. Exemption of this product shall not be construed as an exemption to sell, offer for sale, or advertise any components of the catalytic converter, as individual devices.

3. Any oral or written references to this Executive Order or its content by ACAT, its principals, agents, employees, distributors, dealers, or other representatives must include the disclaimer that the Executive Order or the exemption it provides is not an endorsement or approval of any emission reduction claims for the catalytic converter and is only a finding that the catalytic converter is exempt from the prohibitions of VC Sections 27156 and 38391.

4. ACAT's installation instructions for the new catalytic converter must conform to requirements in Section (h) of the Converter Evaluation Procedures.

5. Installation of the catalytic converter shall not cause the relocation of an oxygen sensor. Oxygen sensors must be installed in the same location, position and orientation as prescribed in the original equipment manufacturer's configurations.

6. Upon installation, the catalytic converter must carry a manufacturer's warranty for five years or 50,000 miles as prescribed in Section (f)(2) of the Converter Evaluation Procedures.

7. ACAT and its vendors may not advertise the new aftermarket catalytic converter as "high flow or easy flow" catalytic converter or use any phrase that could make them appear to perform better than the original equipment manufacturer catalytic converters.

8. Any marketing arrangement of the new aftermarket catalytic converter by a third party, which involves the use of packaging identification different from the ones described in this Executive Order, must be approved by CARB prior to shipment.

9. ACAT, its associates, vendors, other businesses, and individuals associated with ACAT, may not sell or supply new aftermarket catalytic converter substrates to a third party to be assembled in a different facility and marketed under this Executive Order without approval from CARB.

10. ACAT shall comply with the quality control procedures and reporting requirements in Section (f)(5) of the Converter Evaluation Procedures.

11. Quality control reports must be submitted on a quarterly basis and warranty information reports must be submitted on a semi-annual basis.

12. ACAT must provide a permanent label or stamp as specified under Section (f)(1) of the Converter Evaluation Procedures.

13. ACAT's vehicle application catalog must conform with the requirements as specified under Section (f)(4) of the Converter Evaluation Procedures.

Violation of any of the above conditions shall be grounds for revocation of this order. The order may be revoked only after a 30-day written notice of intention to revoke it, during which period the holder of the order may request in writing a hearing to contest the proposed revocation. If a hearing is requested, it shall be held within 30 days of receipt of the request, and the order may not be revoked until a determination is made, after the hearing, that grounds for revocation exist.
