The modeled 2028 base year 8-hour ozone design values were found to be above the 70 ppb NAAQS for 75 monitoring locations. By 2035, 46 states will be in attainment with the 2015 ozone NAAQS of 70 ppb (only counties in California and Utah remain in nonattainment). Source: MECA. ppb in the west (San Bernardino, CA) and 4.9
The US Environmental Protection Agency (EPA) has launched the Cleaner Trucks Initiative (CTI) to further decrease NO x emissions from on-highway heavy-duty trucks and engines. EPA last revised NO x standards for on-highway heavy-duty trucks and engines in January 2001. The Agency is not required by statue to update the standard.
Alternative-fuel technology company ROUSH CleanTech has developed the first available propane autogas engine certified to California Air Resources Board’s (CARB’s) optional low oxides of nitrogen emissions standard for heavy-duty engines with 0.02 g/bhp-hr heavy-duty engine standard. g/bhp-hr heavy-duty engine standard.
Commercial workboat engines are staying in service more than two times longer than predicted by the US Environmental Protection Agency (EPA), according to new research from the Diesel Technology Forum (DTF) and Environmental Defense Fund (EDF). This report underscores that more, older engines remain in service today.
VOCs, primarily emitted from the tailpipes of vehicles, are a key ingredient in the formation of ground-level ozone which, at high levels, can harm people’s lungs and damage crops and other plants. The reason is simple: cars are getting cleaner. —lead author Carsten Warneke, Ph.D., Warneke, C., de Gouw, J. Holloway, J.
The California Air Resources Board approved changes to an existing $28 million financial assistance program this week that will significantly help more California independent truckers qualify for the purchase of a cleaner-running vehicle. VIP is part of the state’s overall plan to cut toxic diesel emissions 85 percent by 2020.
For heavy-duty vehicles, the State SIP Strategy calls for combustion engine technology that is effectively 90% cleaner than today’s standards. Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions. emissions by more than 20%.
Five technology paths for very-low-NO x and GHG emissions from heavy-duty natural gas engines. SoCalGas), showcases the technologies currently under development that could deliver near-zero-emission heavy-duty natural gas engines by the end of this decade. Click to enlarge. Click to enlarge. grams per brake horsepower-hour (g/bhp-hr).
The US EPA issued an Advance Notice of Proposed Rulemaking (ANPR) for the Cleaner Trucks Initiative (CTI). The eventual CTI rulemaking will establish new, more stringent emission standards for NO x and other pollutants for highway heavy-duty engines. EPA is seeking input from the public and interested stakeholders.
Furthermore, airborne chemicals that originate inside a house don’t stay there: Volatile organic compounds (VOCs) from products such as shampoo, perfume and cleaning solutions eventually escape outside and contribute to ozone and fine particle formation, making up an even greater source of global atmospheric air pollution than cars and trucks do.
Each of the four recipients will match a percentage of the grant amount with their own funds to purchase compressed natural gas-powered vehicles; retrofit diesel engines with cleaner technology; replace older, more polluting diesel buses with cleaner diesel buses; or purchase hybrid electric-powered buses.
The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. As transportation gets cleaner, those other sources become more and more important. —Brian McDonald, corresponding author.
A report released by the University of California Riverside’s College of Engineering-Center for Environmental Research and Technology (CE-CERT), found that the new 8.9L Cummins Westport ISL G near-zero (NZ) natural gas engine ( earlier post ) meets and exceeds the certification standards during a full range of duty cycles.
Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles.
Ships, especially ocean-going vessels, are powered by very large diesel engines that generate a tremendous amount of pollution impacting air quality onshore. One finding was that container ships encountered off the Port of Houston, where no clean-fuel use is required, emitted four times as much sulfur dioxide.
Advanced ignition technologies, such as those offered by TPS, have been widely recognized as enablers to achieving higher combustion efficiency and lower emissions for gasoline-powered engines. In particular, TPS technology offers a groundbreaking approach to reducing emissions from combustion engines and improving the environment.
exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology.
ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 Under current control programs (left) and under the Cleaner Technologies and Fuels scenario (right). Vision 2.0 Projected statewide light duty vehicle technology mix. Click to enlarge.
The Green Aviation Summit is highlighting the depth and breadth of NASA’s work to develop aviation technologies that are designed to make air transportation cleaner and quieter for the environment, with fewer delays for travelers. ” —Ames Research Center Director Simon “Pete” Worden.
A new report from the US Environmental Protection Agency (EPA) finds that air pollution at US ports can be reduced significantly at all port types and sizes through a variety of strategies and cleaner technologies. national ambient air quality standards (NAAQS). Click to enlarge. relative reductions from drayage trucks.
While current state and federal measures are on target to reduce toxic diesel locomotive emissions 65% or more by 2020, additional measures recommended by ARB staff would ultimately provide up to 85% or greater emissions reductions within the rail yards over the same period, resulting in cleaner air for nearby residential neighborhoods as well.
The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation. Damages from electricity generation. The report was sponsored by the US Department of the Treasury.
Car and truck engines used to be the largest sources of anthropogenic black carbon emissions in California; the existing air quality policies will virtually eliminate black carbon emissions from on-road diesel engines within 10 years. The SLCP Strategy is due to come before the Board for consideration in March 2017.
“Coloradans want low- and zero-emissions vehicles because they help them get where they’re going while breathing cleaner air and saving money. Notably, the release says that the standard does not prohibit the sale or use of non-electric vehicles with internal combustion engines (ICEs).
As the trend toward cleaner technologies with reduced exhaust emissions continues through the use of catalytic converters, diesel particulate filters (DPF), and improved fuels and engines, non-exhaust PM will soon surpass exhaust emissions and may well become dominant by 2020 both in terms of emissions and contributions to air quality.
Almost half the new buses are fueled by cleaner-burning propane or compressed natural gas; the others are cleaner-burning diesel engines. In each case, the new engines will reduce oxide emissions and other pollutants like sulfur dioxide, volatile organic compounds, and particulate. Another $7.3
But rather than giving into despair, some engineers, policymakers, and activists are pursuing a novel strategy. In the stratosphere, in particular, they’re concerned about the health of the ozone layer and also how this might trap heat in the stratosphere in ways that changes the way that the atmosphere works.
In October 2007, Governor Arnold Schwarzenegger signed AB 118 which provides approximately $200 million annually through 2015 to the California Energy Commission, the Bureau of Automotive Repair and the ARB to fund air quality improvement projects that will accelerate clean engine technologies. ARB was appropriated approximately $42.3
Eligible diesel emission reduction solutions include verified emission control technologies such as retrofit devices, cleaner fuels, and engine upgrades, verified idle reduction technologies, verified aerodynamic technologies and low rolling resistance tires, certified engine repowers, and/or vehicle or equipment replacement.
