ADDRESS: GOREWAY DRIVE MISSISSAUGA, ON L4V 1P7 CANADA PHONE: (800) FAX: (905) mamannan@nett.ca WEB SITE: 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 International 1 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 selective catalytic reduction (SCR) technology. 1 RTI International is a trade name of Research Triangle Institute. i

2 ENVIRONMENTAL TECHNOLOGY VERIFICATION TEST DESCRIPTION All tests were performed in accordance with the Test/QA Plan for the Verification Testing of Selective Catalytic Reduction Control Technologies for Highway, Nonroad, and Stationary Use Diesel Engines and the Test-Specific Addendum to ETV Mobile Source Test/QA Plan for Nett Technologies for the BlueMAX 100 Version A 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 August 2009 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 were made. A summary of the ETV test is provided in Table 1. Table 1. Summary of the Environmental Technology Verification Test Test type Non-road steady-state FTP and NRTC Engine family Box NR-7 Tier 1 Engine make, model year Caterpillar 3406, 1989 (upgraded in 2006) Service class Non-road, heavy-duty diesel engine Engine rated power 306 hp at 2100 rpm Engine displacement 14.6 L, inline six cylinder Technology Nett Technologies, Inc. s BlueMAX 100 version A Technology description Urea-based SCR Test cycle or mode description Test fuel description Critical measurements Ancillary measurements Three hot-start, eight-mode steady-state tests according to FTP test and the nonroad transient cycle for baseline engine, degreened, and aged systems Ultra-low sulfur diesel fuel with 15 ppm sulfur maximum PM, NO x, HC, and CO CO 2, NO, NO 2 (by calculation), NH 3, soluble organic fraction of PM, exhaust backpressure, exhaust temperature, and fuel consumption CO 2 = carbon dioxide, FTP = Federal Test Procedure, hp = horsepower, NO = nitric oxide, NO 2 = nitrogen dioxide, NH 3 = ammonia, NRTC = Nonroad Transient Cycle, ppm = parts per million, rpm = revolutions per minute. VERIFIED TECHNOLOGY DESCRIPTION Nett Technologies BlueMAX 100 version A Urea-Based SCR System utilizes a zeolite catalyst coating on a cordierite honeycomb substrate for heavy-duty diesel nonroad engines for use with commercial ultra-low sulfur diesel fuel (ULSD) conforming to 40 Code of Federal Regulations 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 Nett Technologies BlueMAX 100 version A Urea-Based SCR System on nonroad 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, urea consumption, urea pressure, urea tank leakage, and a mechanism to interrupt engine restart in the event of an empty urea tank. ii

The functional tests demonstrated the BlueMAX 100 system was operating properly; however, a malfunction in the urea dosing pump and the associated error indicator lamp occurred during emission testing. As a result, the urea pump was replaced before continuing with the emissions testing. 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 the 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 Nett Technologies BlueMAX 100 version A Urea-Based SCR System for the stated application. Extrapolation outside of that range should be performed 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 Nett Technologies BlueMAX 100 version A Urea-Based SCR System within the range of applicability of the statement. signed by Andrew Gillespie for 6/16/2010 signed by Jason Hill 6/3/2010 Sally Gutierrez Date Jason Hill Date Director Director National Risk Management Research Laboratory Air Pollution Control Technology Center Office of Research and Development RTI International United States Environmental Protection Agency NOTICE: ETV verifications are based on an evaluation of technology performance under specific, predetermined criteria and the appropriate QA procedures.
