In a statement released this morning, President Barack Obama said he has requested that US Environmental Protection Agency (EPA) Administrator Lisa Jackson withdraw the agency’s draft Ozone National Ambient Air Quality Standards (NAAQS) rulemaking. Earlier post.) National Ambient Air Quality Standards (NAAQS).
Counties where measured ozone is above proposed range of standards, based on 2011-2013 monitoring data. Earlier this year, EPA staff had recommended the further reduction of this primary ozone standard from the current 75 ppb (parts per billion) to a revised level within the range of 70 ppb to 60 ppb—and preferably below 70 ppb.
Counties projected to violate proposed Primary 8-hour Ground-Level Ozone Standards in 2020. The United States Environmental Protection Agency has proposed the strictest standards to date for ground-level ozone. EPA is proposing an accelerated schedule for designating areas for the primary ozone standard. Source: EPA.
The California Air Resources Board today approved a statewide plan for attaining the federal health-based standard for ozone, typically experienced as smog. The 2022 State Implementation Plan Strategy identifies the state’s control strategy for meeting the federal 70 parts per billion, 8-hour ozone standard over the next 15 years.
Denver represents an interesting case study for exploring potential PHEV impacts because it violates the federal air quality standard for ozone and because several large EGUs [electricity generating units] are located in or near the urbanized area. Ozone concentration increases were modeled for small areas near central Denver.
issued its final rule revising the National Ambient Air Quality Standards (NAAQS) for ground-level ozone to 70 parts per billion (ppb) from 75 ppb to protect public health. Ground-level ozone forms when nitrogen oxides (NO x ) and volatile organic compounds (VOCs) react in the air. The US Environmental Protection Agency (EPA).
The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). Climate and the Ozone Layer. Source: UNEP. Click to enlarge.
Source: “Hidden Costs of Energy”. When such market failures occur, a case can be made for government interventions—such as regulations, taxes or tradable permits—to address these external costs, the report says.

This program successfully committed $90 million over seven years for research, demonstration, and deployment projects to reduce the cost of fuel cells for transit use. The proposer must provide at least 15% of the cost of all transit bus acquisitions and 10% of the cost for all related equipment and facilities. 7407(d)); or.
This proposal reduces emissions contributing to fine particle (PM 2.5 ) and ozone nonattainment that often travel across state lines. SO 2 and NO x react in the atmosphere to form fine particle pollution and ground-level ozone (smog), which are linked to widespread illnesses and premature deaths. NO x emissions would drop by 52%.
These proposed amounts are expected to fund up to 95% of the cost of a battery-electric school bus; to fund the incremental costs of a zero-emission transit bus above the typical Federal Transit Administration funding; and to fund a large portion of the incremental costs for a battery-electric shuttle bus. . $10
By authorizing real, permanent offsets from farms, forests, and businesses that are not covered by cap-and-trade, we can reduce the costs of compliance with the program and encourage investments in sustainable practices throughout the California economy. Destruction of Ozone Depleting Substances. Urban forestry. Dairy manure digesters.
reductions; annual NO x reductions; and ozone-season NO x. nonattainment and maintenance areas based on: the magnitude of a state’s contribution; the cost of controlling pollution from various sources; and. Ozone Season NO x Power Plant Emissions. The CSAPR includes separate requirements for annual SO 2. reductions.
The rail sector is the only transportation modality without significant emissions related development that is feasible in the near-term to eliminate ozone, smog and GHG emissions, OptiFuel says. In production, OptiFuel will provide its proven locomotive CNG fueling station solution and expect the CNG to cost between 0.70
Although the impact of carbon emissions on the climate is well documented, combustion engines also produce other harmful pollutants, such as particulate matter and the precursors to ground-level ozone. Such pollutants can trigger a variety of health problems, including asthma, emphysema, chronic bronchitis and ultimately premature death.
The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. times the cost of implementing a cap-and-trade program.
At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. SCR systems would reduce NO x emissions at the cost of increased aircraft weight and specific fuel consumption due to the pressure drop in the core stream induced by the catalyst.
NO x is a precursor for both ground level ozone and secondary PM 2.5 While the cost of new heavy-duty trucks has increased at approximately 1% per year, the cost of emission controls has come down, representing a lower percentage of the cost of a new truck.
The draft CTGs include information on cost-effective control technologies to help states in making their RACT determinations. Costs and benefits. EPA conducted a regulatory impact analysis (RIA) that looks at illustrative benefits and costs of the proposed NSPS for the years 2020 and 2025.
The US Environmental Protection Agency’s (EPA) Targeted Air Shed Grant Program focuses on the regions that have the highest ozone and particulate matter (PM) pollution, including California’s South Coast Air Basin.
The report did note, however, that there are some serious questions over adverse effects with this method, particularly depletion of stratospheric ozone. Earlier post.). Geoengineering and its consequences are the price we may have to pay for failure to act on climate change.”. Evaluating candidate particles.
A key barrier to achieving RFS2 is the high cost of producing biofuels compared to petroleum-based fuels and the large capital investments required to put billions of gallons of production capacity in place. Resolving most of the barriers is necessary to achieving RFS2, and many of them are interrelated as illustrated by the examples below.
Traditional ignition systems when used to enhance internal combustion engine (ICE) efficiency and lower emissions are handicapped with high energy consumption and poor durability leading to an unattractive cost of ownership. TPS ignition system. hp diesel engine.
These incentives help to pay the difference between the cost of alternative-fuel vehicles and conventional vehicles. Currently, the state’s transportation sector accounts for nearly 40% of the state''s greenhouse gas emissions; more than 95% of all transportation energy consumed in California is petroleum-based. . $15
In particular, silicon nanowires (SiNW) are widely studied as a promising anode material for high-capacity LIBs due to its low cost of fabrication and volume production potential. As a result, high-capacity LIB technologies are currently under development at lab scale with silicon nanostructured anode materials.
This is in contrast to the conventional mobile AC system, where the cabin air is directly cooled by the refrigerant HFC-134a, which is ozone safe but has a high GWP. The SL-MAC project is on schedule, as expected, with anticipated environmental and cost advantages to be determined in the next stages. — Dr. Stephen O.
Regarding future Greenhouse Gas (GHG) emission regulations (Pavley 2), staff is evaluating studies of the feasibility and cost of advanced technologies to reduce GHG emissions that could achieve widespread sales and acceptance in the 2017-2025 timeframe.
However, since the cost of the hydrous ethanol is significantly lower, hydrous ethanol will provide a lower cost per mile travelled, assuming the processing cost savings is passed on to the consumer. Current Legal Requirement for Use of Anhydrous Ethanol in the United States. 40 CFR § 80.27 Pursuant to 40 CFR § 80.27(a)(2):
Estimates of the economic costs of mitigation vary widely. Additionally, reducing transport emissions of particulate matter (including black carbon), tropospheric ozone and aerosol precursors (including NO x ) can have human health and mitigation co?benefits In business-as-usual scenarios, consumption grows by 1.6 to 3% per year.
The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone. However, concerns about engine performance and the cost of fuel production led the state to allow higher aromatic levels in diesel fuel.
The Haifa region began air quality monitoring some 30 years ago; the metropolitan area now has the densest air quality monitoring network in Israel with 27 continuous monitoring stations that measure criteria pollutants including sulfur oxides, nitrogen oxides, ozone, particulates and more.
Total cost of those five measures is estimated to be $3.9 NO x helps create ground-level ozone, or smog. Once all steps are taken, Californians can expect to see a reduction of about 69 tons per day of NO x (a key ingredient of smog), and a reduction of about three tons per day of toxic diesel soot.
In addition, other studies have shown that increases in PM 2.5 , NO 2 , and ozone were associated with lower test scores that were “equivalent to the effects of short-term reductions of thousands of dollars in district median household income.”
The Alzeta Corporation of California will partner with LBNL to destroy effluents from semiconductor processing that could potentially harm the ozone layer in a project titled “Improving Gas Reactor Design With Complex Non-Standard Reaction Mechanisms in a Reactive Flow Model.”. Harper International Corp.
In order to achieve the 2008 Ozone National Ambient Air Quality Standards set by US EPA, CARB estimates that the South Coast Air Basin alone (including Los Angeles) will need an 80% reduction in NO x emissions by 2031. CARB said it looked forward to continued cooperation with the federal agencies on this long-term effort.
UCS advocates relentlessly for cleaner gasoline vehicles and dismisses plug-ins of all sorts, the Sierra Club strikes deals with Ford to promote a few thousand gasoline-dependent hybrids in exchange for advertising dollars, and the NRDC jumped on the biofuels bandwagon just as the cost of corn ethanol became impossible to ignore.
Only the Stanza Altima GLE came with an automatic transmission as standard equipment for 1993; a five-speed manual was the base transmission for the lesser trim levels and the optional automatic added $825 ($1,755 today) to the cost of those cars. There's no mention of the Stanza name in this TV commercial Ozone-friendly air conditioning!
Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. The last of these issues was perhaps the most vexing, prompting the U.S.
California’s and, potentially, EPA’s move toward further heavy-duty NO x reductions to meet National Ambient Air Quality Standards for ozone will be critical. These new targets need to be set for the research efforts.
In 2004, the Centralina region (the Greater Charlotte metro area, which straddles the North CarolinaSouth Carolina border) was designated as a non-attainment area for ozone under the Clean Air Act. The area stood to lose billions of dollars of federal funding for a wide variety of projects if the areas air quality didnt improve.
For example, Nevada Energy provides a 75% rebate of the cost of electric school buses and eligible chargers with its Electric School Bus Incentives program. You can find state-level electric school bus funding programs using the Alternative Fuels Data Center search tool.
For hospitals and medical centers with an ambulatory or EMS fleet, switching from internal combustion engine (ICE) vehicles to EVs could save as much as 75% in fleet maintenance costs. With less maintenance and lower fuel costs , switching to an electric fleet can significantly reduce the cost of operating your fleet.
