arbcombo -- Public Workshop To Discuss Proposed Amendments to The Off-Road Large Spark-Ignition Engine Fleet Regulation

Public Workshop To Discuss Proposed Amendments to The Off-Road
Large Spark-Ignition Engine Fleet Regulation – Save the Dates
June 8, June 10, and June 12, 2015.

Air Resources Board (ARB/Board) staff intends to conduct a public
workshop to discuss proposed amendments to the Large
Spark-Ignition Engine Fleet Regulation (LSI Fleet Regulation) on
the dates below. At the workshop, ARB staff will present initial
near- and long-term concepts to amend the LSI Fleet Regulation.
This includes aligning with the reporting and labeling
requirements similar to the existing In-Use Off-Road
Diesel-Fueled Fleets Regulation to both better characterize the
existing California LSI fleet, and to ensure compliance with the
existing LSI regulation. Staff is also interested in hearing
from affected stakeholders on alternatives to achieving these
same objectives.

The workshops will be held in the following time and location:

Date: June 8, 2015
Time: 10:00 a.m. – 12:00 p.m.
Location: Cal EPA Building
Byron Sher Auditorium
1001 I Street
Sacramento, CA 95814

Date: June 10, 2015
Time: 10:00 a.m. – 12:00 p.m.
Location: San Joaquin Valley Air Pollution Control District
1990 E. Gettysburg Avenue
Fresno, CA 93726

Date: June 12, 2015
Time: 10:00 a.m. – 12:00 p.m.
Location: South Coast Air Quality Management District
Auditorium
21865 Copley Drive
Diamond Bar, CA 91765

If you have any questions regarding this workshop, please contact
Mr. Todd Sterling, Air Pollution Specialist, at (916) 323-2397 or
Todd.Sterling@arb.ca.gov.

Background
To achieve its healthy air quality, climate, and sustainability
goals, California must take effective, well-coordinated actions
to transition to a zero emission transportation system for both
passengers and freight. The freight transport system is a major
economic engine for California, but also accounts for about half
of toxic diesel particulate matter, 45 percent of the emissions
of nitrogen oxides (NOx) that form ozone and fine particulate
matter in the atmosphere, and 6 percent of the greenhouse gas
emissions in California. These statistics include emissions from
trucks, ships, locomotives, aircraft, harbor craft, and all types
of equipment used to move freight at seaports, airports, rail
yards, warehouses and distribution centers. Proposed amendments
to the LSI Fleet Regulation are identified in the Sustainable
Freight Strategy as a Near-Term ARB Measure.

In 1998, ARB first adopted emission standards for new
spark-ignited engines used in propane forklifts and other similar
industrial equipment. These engines are referred to as LSI
engines. In addition to forklifts, the LSI category includes
airport ground support equipment (GSE), sweepers and scrubbers,
generator sets, small irrigation pumps, and a variety of other
similar equipment.

The LSI Fleet Regulation applies to operators of forklifts,
sweeper/scrubbers, industrial tow tractors, and airport GSE.
These vehicles are found in approximately 2,000 LSI fleets in
California in industries as diverse as manufacturing, wholesale,
transportation and utilities, retail, services, and construction,
as well as public agencies. The 2006 LSI rulemaking and 2010
amendments required operators of in-use fleets to achieve
specific hydrocarbon + NOx fleet average emission level (FAEL)
standards that became more stringent over time, the lowest FAEL
for large and medium fleets was to be achieved in 2013. The
standards are also more stringent for forklifts than they are for
non-forklift LSI equipment. The stringency of the standards
reflects the differences in availability of retrofit devices for
the four categories of in-use LSI equipment as well as the
greater ability of large fleets to incorporate zero and near
zero-emission equipment into their operations. Since 2007, fleet
operators are required to keep updated fleet records at their
facilities until June 30, 2016. Small fleets and in-field
equipment are exempt from the LSI Fleet Regulation.

arbcombo -- ARB Research Seminar: Evaluation of Regional Isoprene Emission Estimates in California Based on Direct Airborne Flux Measurements

"Evaluation of Regional Isoprene Emission Estimates in California
Based on Direct Airborne Flux Measurements".

Allen H. Goldstein, Ph.D., and
Pawel K. Misztal, Ph.D.,

Accurately modeled Biogenic Volatile Organic Compound (BVOC)
emissions are an essential input to atmospheric chemistry
simulations of ozone and particle formation. BVOC emission models
originate from leaf and branch level measurements with scaling to
regional or larger spatial levels based on vegetation landcover
data derived Basal Emission Factors (BEFs), but they generally
lack validation by regional scale measurements. We directly
assess isoprene emission-factor databases for BVOC emission
models by deriving BEFs from direct airborne fluxes aggregated at
2 km resolution and averaged spatially over ecoregions covering
~10,000 km of California. Ecoregion averaged BEFs from the
landcover used by the Model of Emissions of Gases and Aerosols
from Nature (MEGAN) v. 2.1 BVOC emission model agreed within 10%
(r²=0.82) with measured BEFs, with few discrepancies (either
overestimation or underestimation). For more go to the

arbcombo -- ARB Research Seminar: Deriving Roof Albedo for Seven California Cities Using Remote Sensing

Deriving Roof Albedo for Seven California Cities Using Remote
Sensing.

George Ban-Weiss Ph.D., University of Southern California,
Ronnen Levinson, Ph.D., Lawrence Berkeley National Laboratory,
and Jordan Woods, University of California, Berkeley

Thursday, June 11, 2015 1:30 pm, PDT (WEBCAST)
Sierra Hearing Room, 2nd Floor, Cal/EPA Building
1001 I Street, Sacramento, California

Cool roofs reflect sunlight and therefore can reduce cooling
energy use in buildings. Further, since roofs typically cover
about 20-25% of a city, widespread deployment of cool roofs could
mitigate the urban heat island effect and partially counter urban
temperature increases associated with global scale climate
change. The magnitude of these potential benefits for a given
city depends on the increase in albedo that can be achieved using
reflective roofs. Assessing this increase requires knowledge of
roof albedo at the city scale, which until now has been hindered
by a lack of reflectance data with sufficient spatial coverage,
spatial resolution, and spectral detail.
