The University of Minnesota and research partners West Virginia University, Carnegie Mellon University, Tampere
University, Paul Scherrer Institute, University of California at Riverside, Caterpillar, Inc., and Cummins, Inc. undertook the
study titled Diesel Aerosol Sampling Methodology to sample, characterize and quantify particles in Diesel exhaust. The goal
of this project (E-43) was to develop Diesel aerosol sampling methods for the laboratory that would produce particle size
distributions similar to those obtained under real-world roadway conditions. The study was carried out at four locations with
measurements on four test trucks powered by Caterpillar and Cummins engines and several engines installed on engine
dynamometers. Standard certification (EPA) and market basket blends of California fuels (CA fuel) were used for all tests. A
mobile laboratory was built and used to conduct onroad, chase studies, and a wind tunnel study was carried out at the Langley
Wind Tunnel in Langley, Virginia. Engine and chassis dynamometer laboratory studies were carried out at Caterpillar,
Cummins, and at the University of Minnesota.

The University of Minnesota formed an international research team to conduct the CRC E-43 project Diesel Aerosol
Sampling Methodology. The objectives of the E-43 project were: 1. Determine the actual particle size distribution and particle
number concentration in the exhaust plume from heavy-duty diesel vehicles operated on the road. 2. Compare on-road aerosol
data with data generated in emissions test facilities to determine if current emission test facility sampling and analysis methods
are adequate for characterizing particle size observed on the road. 3. Examine particle transformations as the plume disperses
downwind of the roadway in a typical urban situation. 4. Characterize the bulk diesel particulate matter chemical composition
and to determine surface properties and composition. The goal of E-43 was to develop diesel aerosol sampling methods for
the laboratory that would produce results similar to those obtained under real- world roadway conditions. As part of E-43, a
field study was carried out using two test trucks powered by Caterpillar engines, a 3406C and a 3406E. A central goal of the
E-43 project was to recommend methods and procedures that when used in the laboratory would improve the simulation of
on-road exhaust aerosol sampling. Detailed recommendations are made in the E-43 Final Report along with a discussion of
the theory behind nanoparticle formation and growth.

Assessment of Unabated Facility Emission Potentials for Evaluating Airborne Radionuclide Monitoring Requirements
at Pacific Northwest National Laboratory, 1999

Assessments were performed to evaluate compliance with the airborne radionuclide emission monitoring requirements in
the National Emission Standards for Hazardous Air Pollutants. In these assessments, potential unabated offsite doses were
evaluated for emission locations at facilities owned by the U.S. Department of Energy and operated by Pacific Northwest
National Laboratory (pacific Northwest) on the Hanford Site. Two of the facilities evaluated, 325 Building Radiochemical
Processing Laboratory, and 331 Building Life Sciences Laboratory met state and federal criteria for continuous sampling of
airborne radionuclide emissions. One other building, the 3720 Environmental Sciences Laboratory, was recognized as being
in transition with the potential for meeting the continuous sampling criteria.
