The U.S. Environmental Protection
Agency (EPA) said it wants to cut the
amount of ethanol and other biofuels
that must be blended into the nation’s
fuel supply. EPA’s proposal for 2014
blending volumes under the federal Re-newable Fuel Standard are lower than
the 2013 requirements and far less than
called for in a 2007 law that expanded
The EPA is proposing a 15. 21 billion
gal. requirement for 2014, down from
16. 55 billion gal. in 2013, marking the
first time the agency has lowered the
target from the prior year.
A senior administration official said
the Obama administration is firmly supportive of biofuels, but said “market, infrastructure and other constraints” warrant paring back the mandate.
Volvo Trucks North America began
delivery of 35 compressed natural gas-powered Volvo VNL tractors to grocery
wholesaler and retailer Supervalu Inc.
The CNG-powered Volvo daycabs will
operate out of Supervalu’s Mechanicsville, Va., distribution center, which recently installed a fast-fill CNG station.
The distribution center operates 105
tractors and the company has set a goal
of converting 65% of its fleet to natural
gas by 2015. Supervalu operates 20 distribution centers across the U.S. and has
more than 400 trucks in its national com-pany-owned fleet. The Volvo VNL truck
incorporates a 12 L Cummins-Westport
ISX12 G engine.
The California Air Resources Board
(CARB) is offering some relief to fleets
working “in good faith” to meet state deadlines for upgrading aging diesel fleets.
The agency said it would allow more time
for many fleets to install particulate matter
(PM) filters on diesel buses and trucks.
The state’s Truck and Bus Regulation,
which was adopted in 2008, requires that
many of those buses and trucks with 1996
to 2006 engine models to incorporate PM
filters by Jan. 1, 2014. CARB is now offering additional time in some areas to meet
the requirements along with some other
options. Fleet owners interested in taking
advantage of the new flexibility must register with CARB by Jan. 31, 2014.
The EPA’s Construction Equipment
Funding Opportunity pilot program
provides up to $120,000 for up to five
engines per applicant. Rebates are available to the owners of older construction
equipment to either replace older engines that do not meet emissions standards with engines that meet either Tier
2 or Tier 3 standards
Rebates are also available to the owners of equipment that meet more modern
Tier 2 or Tier 3 emissions standards to
install a diesel particulate filter (DPF).
Targeted public funding is also available to retrofit or repower equipment
found only in regions with poor air quality.

Carrier Transicold said its optional
engine emissions system (EES) for trailer refrigeration units has received conditional verification from CARB.
The CARB level 3+ verified diesel
emissions control (VDEC) device can be
included on new trailer refrigeration units
or added later for users who do not ini-
tially require it, the company said. A lev-
el 3+ VDEC device reduces particulate
emissions to CARB’s ultralow emissions
requirements, while also reducing nitro-
The company’s latest trailer refrigera-
tion unit engines are already certified for
“evergreen” compliance with the 2013
EPA Tier 4 standard for engines less
than 25 hp, allowing for indefinite use
throughout North America, except in
California. In California, CARB requires
that a VDEC strategy be applied to units
in that horsepower class for use in the
state beyond the initial seven years.
Carrier Transicold’s EES system is
conditionally verified for use on Car-
rier’s single-temperature X4-7300 and
7500 models, and Vector 8500 single-
temperature and 8600MT multitem-
Retrofits can be done to in-use engines
with less than 3000 hours of operation
at the time of installation. New transport
reefer units can be fitted with an EES at
the factory, or may be retrofitted.
Fairbanks Morse Engine has signed
a joint development and licensing agreement with opposed-piston engine developer Achates Power to reduce emissions
and fuel consumption of Fairbanks Morse
proprietary diesel and dual-fuel opposed-piston engines. The opposed-piston engines of Beloit, Wis.-based Fairbanks
Morse are used in applications including
nuclear standby power, emergency stationary power, telecommunications networks and commercial installations. dp
