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 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.
RTI International is a trade name of Research Triangle Institute.

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 (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 made. A summary of the ETV test is provided in Table 1.

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 89.330.
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.

VERIFICATION OF PERFORMANCE
The Nett Technologies' Blue MAX 100 version A Urea-Based SCR System achieved the reduction in tailpipe
emissions shown in Table 2 compared to baseline operation without the system.

a The emissions reduction could not be distinguished from zero with 95% confidence.
The emissions reduction could not be distinguished from 100% with 95% confidence.
Confidence limits could not be determined for NRTC (Nonroad Transient Cycle) emissions reductions because replicate test
runs were not performed.
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.
