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 peerreviewed 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. i

The Air Pollution Control Technology Center (APCT Center), which is one of six centers under the ETV Program, is operated by RTI International 1 (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 SCCRT, v.1 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 (NO x ), 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. Engine family Table 1.

VERIFIED TECHNOLOGY DESCRIPTION The Johnson Matthey SCCRT, v.1 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.1 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. a Table 2a.

The table describes the verified emissions reduction percentages for the degreened and aged systems for particulate matter, nitrogen oxides, hydrocarbons, and carbon monoxide. 95% confidence limits for these reductions are also listed. End of table description. 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. iii
