The U.S. Environmental Protection Agency (EPA) 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. The ETV Program 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.
The ETV Program 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 International1 in cooperation with EPA's National Risk Management Research
RTI International is a trade name of Research Triangle Institute.

Laboratory. The APCT Center has evaluated the performance of an emission control system consisting of a flow-
through partial filter combined with a diesel oxidation catalyst (DOC).
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 and Nonroad Use Diesel Engines and the
Test-Specific Addendum to ETV Mobile Source Test/QA Plan for Johnson Mattheyfor the PCRT2® 1000, V.2 System.
These documents are written in accordance with the applicable generic verification protocol and include
requirements for quality management and QA, procedures for product selection and auditing of the test laboratories,
and the test reporting format.
The mobile diesel engine air pollution control technology was tested August 2008 at Southwest Research Institute.
The performance verified was the percentage of emissions 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 Johnson Matthey PCRT2® 1000, v.2 system is a partial continuously regenerating technology (PCRT) system
that consists of a flow-through partial filter combined with a DOC. The system is designed for low temperature
exhaust resulting from intermittent loads from medium and heavy heavy-duty diesel on-highway non-urban bus
engines. 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 Johnson Matthey PCRT2® 1000, v.2 system on highway
engines fueled by ultra-low-sulfur diesel (ULSD) (15 ppm or less) fuel.
VERIFICATION OF PERFORMANCE
The Johnson Matthey PCRT2® 1000, v.2 system achieved the reduction in tailpipe emissions shown in Table 2

The APCT Center quality manager 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. APCT Center
QA staff have conducted technical assessments of the test laboratory procedures 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 Johnson Matthey PCRT2® 1000, v.2 system
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 Johnson MattheyPCRT2®1000, v.2 system within the range of applicability
of the statement.
