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 Center (APCT Center), which is one of six centers under the ETV
Program, is operated by RTI International1 (RTI) in cooperation with EPA's National Risk Management
Research Laboratory. The APCT Center has evaluated the performance of an emission control system
consisting of a selective catalytic reduction (SCR) technology with a catalyzed continuously regenerating
trap (CCRT).
ENVIRONMENTAL TECHNOLOGY VERIFICATION TEST DESCRIPTION
All tests were performed in accordance with the Test/QA Plan for the Verification Testing of Selective
Catalytic Reduction Technologies for Highway, Nonroad and Stationary Use Diesel Engines and the
Test-Specific Addendum to ETV Mobile Source Test/QA Plan for Johnson Matthey for the SCCRJ®, v.l
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 in February 2011 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 also were made. A summary
description of the ETV test is provided in Table 1.

VERIFIED TECHNOLOGY DESCRIPTION
The Johnson Matthey SCCRT®, v.l technology is a urea-based SCR system combined with a CCRT filter
designed for on-highway light, medium, and heavy heavy-duty diesel, urban and non-urban bus, exhaust
gas recirculation (EGR)- or non-EGR-equipped engines for use with commercial ultra-low-sulfur diesel
fuel (ULSD) conforming to 40 Code of Federal Regulations 86.1313-2007.
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 SCCRT®, v. 1 system on
highway engines fueled by ULSD (15 parts per million [ppm] or less) fuel.
The monitoring and notification system that was functionally tested and used with this technology
includes sensors for urea level and leakage detection and a mechanism to interrupt engine restart in the
event of an empty urea tank.
VERIFICATION OF PERFORMANCE
The Johnson Matthey SCCRT®, v.l system achieved the reduction in tailpipe emissions shown in Table 2
compared to baseline operation without the system installed on the test engine. In Table 2, "degreened"
refers to a system with 25-124 hours of accumulated run time while "aged" refers to a system with over
1000 hours of accumulated run time. Additionally, the functional test results indicated proper operation of
the monitoring and warning system.

The APCT Center quality manager has reviewed the test results and quality control (QC) 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 SCCRT®, v.l
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.
