                           Econix DPF—A Diesel Particulate Filter

Pursuant to the authority vested in the Air Resources Board by Section 27156 of the
Vehicle Code; and

Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the
Health and Safety Code and Executive Order G—02—003;

IT IS ORDERED AND RESOLVED: That installation of the Econix DPF—A diesel
particulate filter, manufactured by SK Energy Co., Ltd. of 99, Sorin—dong, Jongro—gu,
Seoul, Korea, has been found not to reduce the effectiveness of the applicable engine
emission control systems, and therefore, the Econix DPF—A diesel particulate filter is
exempt from the prohibitions in Section 27156 of the Vehicle Code for installation on
heavy—duty on—road vehicles equipped with 1992 through 2006 model—year diesel
engines with displacements from 5.9 to 13 liters and horsepower ratings from 150 to
500.

The engines must be certified to 0.10 g/bhp—hr or lower particulate matter standard.
This Executive Order excludes engines originally certified with a diesel particulate filter.

Econix DPF—A diesel particulate filters exempted under this Executive Order and their
major components are identified in Attachment A.

This Executive Order is based on emission tests conducted by SK Energy with the
Econix DPF—A diesel particulate filter. Test data showed no adverse impact on engine
emissions. The same emissions impact is expected when the Econix DPF—A diesel
particulate filter is installed on any of the engines listed above.

This Executive Order is valid provided that installation instructions for the Econix DPF—A
diesel particulate filter do not recommend tuning the engines to specifications different
from those of the engine manufacturer.

Changes made to the design or operating conditions of the Econix DPF—A diesel
particulate filter, as exempted by the Air Resources Board, which adversely affect the
performance of the engine‘s emission control system, shall invalidate this Executive
Order.

Marketing of the Econix DPF—A diesel particulate filter using identification other than that
shown in this Executive Order or for an application other than that listed in this
Executive Order shall be prohibited unless prior approval is obtained from the Air
Resources Board.


                                              _2

This Executive Order shall not apply to any Econix DPF—A diesel particulate filter
advertised, offered for sale, sold with, or installed on a motor vehicle prior to or
concurrent with transfer to an ultimate purchaser.

This Executive Order does not constitute any opinion as to the effect the use of the
Econix DPF—A diesel particulate filter may have on any warranty either expressed or
implied by the engine manufacturer.

No claim of any kind, such as "Approved by the Air Resources Board," may be made
with respect to the action taken herein in any advertising or other oral or written
communication.

In addition to the foregoing, the Air Resources Board reserves the right in the future to
review this Executive Order and the exemption provided herein to assure that the
exempted add—on or modified part continues to meet the standards and procedures of
California Code of Regulations, Title 13, Section 2222, et seq.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION,
ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE
AIR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING
ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF SK ENERGY‘S
ECONIX DPF—A DIESEL PARTICULATE FILTER.

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

Executed at El Monte, California, this      [ [    day of January 2011.

SK ENERGY — ECONIX DPF—A DIESEL PARTICULATE FILTER — D—684


                                         EVALUATION SUMMARY

Manufacturer Name: SK Energy

Name of Device: Econix DPF—A diesel particulate filter

Background:
        SK Energy of 1175 N. Del Rio PI., Ontario, California 91764 has applied for exemption of
its Econix DPF—A diesel particulate filter from the prohibitions in Section 27156 of the California
Vehicle Code (VC 27156). The filter is designed for heavy—duty on—road vehicles equipped with
1992 through 2006 model—year diesel engines.

Recommendation:
         Grant exemption to SK Energy and issue Executive Order D—684. The exemption covers
installation of the Econix DPF—A diesel particulate filter on heavy—duty on—road vehicles
equipped with 1992 through 2006 model—year diesel engines. The engines must meet
0.10 g/bhp—hr or lower particulate matter emission standard. The exemption covers engines
originally certified with a diesel oxidation catalyst (DOC). On DOC engines, the Econix DPF—A
diesel particulate filter will be installed downstream of the DOC with the pressure monitor
installed upstream of the DOC. The exemption excludes any engines originally certified with a
diesel particulate filter. Econix DPF—A diesel particulate filters exempted under this Executive
Order and their major components are identified in Attachment A.

Device Description:
       The Econix DPF—A diesel particulate filter is an actively regenerated filter designed to
reduce diesel particulate matter emissions. It is intended for use on applications that typically
operate for 8 hours and allow regeneration after each operation. The stainless steel fibrous
mesh wall—flow filter is porous and has alternating cells that are plugged to force the exhaust
gases to flow through the cell walls where particulate matter is trapped. The trapped particulate
matter is burned off and the filter is regenerated using diesel fue!l and a burner while the engine
idles. Regeneration is initiated by the vehicle operator following a predetermined schedule
(e.g. after every 8—hour operation) and/or when the operator is notified via lights and alarms in
the cabin. The visual and audible notification occurs when the monitoring system determines
that the filter loading capacity or the backpressure threshold has been reached. Regeneration
time ranges from 8 to 12 minutes. SK Energy recommends filter cleaning once a year and
periodic inspection and cleaning of the fuel system components.

Discussion/Basis for the Recommendation:
       To demonstrate that the Econix DPF—A diesel particulate filter does not adversely affect
engine emissions, SK Energy submitted the following test results:

Notes:

Emissions are weighted averages of one cold start and four hot start tests.
50,000—mile on—road durability testing was conducted on a 1995 Freightliner equipped with a 1995 DDC
Series 60 12.7 liter engine.

         Emission test results showed that emissions with the Econix DPF—A diesel particulate
filter are within the aliowable limits of baseline emissions. Durability testing confirmed proper
regeneration. It is concluded that SK Energy‘s Econix DPF—A diesel particulate filter will not
have any adverse impact on emissions and meets the requirements for a VC 27156 exemption
for the engines listed in the Executive Order.
