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 diesel particulate
filter (DPF) with pre-catalyst.
1 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 Diesel Exhaust
Catalysts, Paniculate Filters, and Engine Modification Control Technologies for Highway and Nonroad Use Diesel
Engines and the Test-Specific Addendum to ETV Mobile Source Test/QA Plan for Baumot for the BA-B 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 October 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 Baumot BA-B technology is a diesel engine retrofit device for light, medium, and heavy heavy-duty diesel on-
highway engines for use with commercial ultra-low-sulfur diesel fuel (ULSD) conforming to 40 Code of Federal
Regulations 86.1313-2007. The BA-B particulate filter is composed of a pre-catalyst on a metal basis and wall-flow
monolith, both of which are coated with a precious metal oxidation catalyst. The 1114 unit is the BA-B variant
specifically designed for use with engines with output of approximately 214-335 horsepower and displacement up to
11 liters.
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 Baumot BA-B 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 a sensor
for exhaust gas backpressure.
VERIFICATION OF PERFORMANCE
The Baumot BA-B 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 for four of
the five errors tested; the error code corresponding to a hose or pipe breakage or damage to the filter was not
triggered successfully.

reduction percentages for the degreened and aged systems for paniculate 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.
This verification statement verifies the emissions characteristics of the Baumot BA-B 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 Baumot BA-B system within the range of applicability of the statement.
