VERIFIED TECHNOLOGIES LIST
•
Verified Technologies List
THE U.S. Environmental Protection Agency (EPA) evaluates the durable emission
reduction capabilities of a wide range of technologies. Through this process, EPA is
working to instill confidence in our stakeholder community that the verified emis-
sion reductions will be achieved in-use. The verification process includes a technical
review of the technology as well as tightly controlled testing to quantify statistically sig-
nificant levels of emission reductions.
The table below summarizes all the diesel retrofit technologies that EPA has
approved, to date, for use in diesel engine retrofit programs through the Voluntary Diesel
Retrofit Program. The table shows approved manufacturers' products, where they are
applicable for use as a verified technology, and the percent reduction (of verified or test-
ed levels) that EPA will recognize for emission reductions for each technology.
Visit www.epa.gov/otaq/retrofit/retroverifiedlist.htm to learn more about these
retrofit technologies and their operating criteria. Be sure to check the Web site regularly
for the most updated list of verified technologies.

1 These effectiveness figures are provisional values subject to change pending final review of the test data.
2 Total PM reduction figures reflect reductions from both tailpipe and crankcase emissions.
Note: For aftertreatment devices, the reductions are based on the installation of retrofit technologies to engines that were
originally produced without diesel oxidation catalysts or diesel particulate filters.

Memorandum of Agreement with California Air Resources Board
EPA signed a Memorandum of Agreement (MOA) with the State of California Air
Resources Board (ARB) for the Coordination and Reciprocity in Diesel Retrofit Device
Verification. The MOA establishes reciprocity in verifications of hardware or device-based
retrofits, and further reinforces EPA's and ARB's commitment to cooperate on the evalu-
ation of retrofit technologies. This agreement commits EPA and ARB to work toward
accepting particulate matter (PM) and nitrogen oxide (NOx) verification levels assigned
by the other's verification programs. Additionally, as retrofit manufacturers initiate and
conduct in-use testing, EPA and ARB agreed to coordinate this testing so data generat-
ed may satisfy the requirements of each program. This MOA is intended to expedite the
verification and introduction of innovative emission reduction technologies. Additionally,
this MOA should reduce the effort needed for retrofit technology manufacturers to com-
plete verification.
In addition to the above list of EPA-verified retrofit technologies, EPA recognizes and
accepts those retrofit hardware strategies or device-based systems that have been veri-
fied by ARB. Information about ARB's Verification Program and its list of verified tech-
nologies can be found at www.arb.ca.gov/diesel/verdev/verdev.htm.
