The U.S. Environmental Protection Agency (EPA) has created the Environmental Technology
Verification (ETV) Program to facilitate the deployment of innovative or improved environmental
technologies through performance verification and dissemination of information. The goal of the
ETV Program is to further environmental protection by accelerating the acceptance and use of
improved and cost-effective technologies. ETV seeks to achieve this goal by providing high-quality,
peer-reviewed data on technology performance to those involved in the design, distribution,
financing, permitting, purchase, and use of environmental technologies.
ETV works in partnership with recognized standards and testing organizations; stakeholder groups,
which consist of buyers, vendor organizations, permitters, and other interested parties; and with the
full participation of individual technology developers. The program evaluates the performance of
innovative technologies by developing test plans that are responsive to the needs of stakeholders,
conducting field or laboratory tests (as appropriate), collecting and analyzing data, and preparing
peer-reviewed reports. All evaluations are conducted in accordance with rigorous quality assurance
(QA) protocols to ensure that data of known and adequate quality are generated and that the results
are defensible.
-------
The Air Pollution Control Technology Verification Center (APCT Center), one of six centers under
the ETV Program, is operated by RTI International (RTI), in cooperation with EPA's National Risk
Management Research Laboratory. The APCT Center has evaluated the performance of an emissions
control system consisting of a precious metal diesel oxidation catalyst and diesel particulate filter for
highway diesel engines.
ETV TEST DESCRIPTION
All tests were performed in accordance with the Test/QA Plan for the Verification Testing of Diesel
Exhaust Catalysts, PM Filters, and Engine Modification Technologies for Highway andNonroad Use
Diesel Engines and the Test-Specific Addendum to ETV Mobile Source Test/QA Plan for PUREM
North America LLCfor the PMF GreenTec system. These documents are written in accordance with
the applicable generic verification protocol and include requirements for quality management, QA,
procedures for product selection, auditing of the test laboratories, and test reporting format.
The mobile diesel engine air pollution control technology was tested at Southwest Research Institute.
The performance verified was the percentage emission reduction achieved by the technology for
particulate matter (PM), nitrogen oxides (NOX), hydrocarbons (HC), and carbon monoxide (CO)
relative to the performance of the same baseline engine without the technology in place. Operating
conditions were documented and ancillary performance measurements were also made. A summary
description of the ETV test is provided in Table 1.

VERIFIED TECHNOLOGY DESCRIPTION
The PUREM PMF GreenTec 1004205.00.0 is a precious metal oxidation catalyst plus a powdered
metal particulate matter filter. This verification statement describes the performance of the tested
technology on the diesel engine and fuels identified in Table 1, and applies only to the use of the
PMF GreenTec 1004205.00.0 on highway engines fueled by ULSD (15 ppm or less) fuel.

VERIFICATION OF PERFORMANCE
The PMF GreenTec 1004205.00.0 achieved the reduction in tailpipe emissions shown in Table 2
compared to baseline operation without the PMF GreenTec system.

The APCT Center QA officer has reviewed the test results and quality control data and has concluded
that the data quality objectives given in the generic verification protocol and test/QA plan have been
attained. EPA and APCT Center QA staff have conducted technical assessments of the test
laboratory and of the data handling. These assessments confirm that the ETV tests were conducted in
accordance with the EPA-approved test/QA plan.
This verification statement verifies the emissions characteristics of the PMF GreenTec 1004205.00.0
for the stated application. Extrapolation outside that range should be done with caution and an
understanding of the scientific principles that control the performance of the technology. This
verification focuses on emissions. Potential technology users may obtain other types of performance
information from the manufacturer.
In accordance with the generic verification protocol, this verification statement is valid, commencing
on the date below, indefinitely for application of the PMF GreenTec 1004205.00.0 within the range
of applicability of the statement.
