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.
The proposed Transport Rule sets in place a new approach that can and will be applied again as further pollution reductions are needed to help areas meet air quality health standards, EPA says. This proposal reduces emissions contributing to fine particle (PM 2.5 ) and ozone nonattainment that often travel across state lines.
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.
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 US Environmental Protection Agency (EPA) has finalized the new Cross-State Air Pollution Rule (CSAPR) (also called the Transport Rule). The Cross-State Air Pollution Rule replaces and strengthens the requirements of the 2005 Clean Air Interstate Rule (CAIR), which the US Court of Appeals for the DC Circuit ordered EPA to revise in 2008.
A new study led by researchers from Northwestern University projects that if electric vehicles replaced 25% of combustion engine cars currently on the road, the United States would save approximately $17 billion annually by avoiding damages from climate change and air pollution. The open-access paper is published in AGU’s journal GeoHealth.
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).
Source: “Hidden Costs of Energy”. The damages the committee was able to quantify were an estimated $120 billion in the US in 2005, a number that reflects primarily health damages from air pollution associated with electricity generation and motor vehicle transportation.

The California Air Resources Board (CARB) approved a plan to mitigate statewide harm from more than 10,000 tons of smog-causing pollutants released in the state due to Volkswagen’s (VW) use of illegal “defeat devices” in diesel passenger cars. More than 10 million Californians live in areas in extreme non-compliance areas for ozone.
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.
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
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.
Sources already subject to the 2012 NSPS requirements for VOC reductions that also would be covered by the proposed 2015 methane requirements would not have to install additional controls, because the controls to reduce VOCs reduce both pollutants. Costs and benefits. Net benefits are estimated at $35 million to $42 million.
(Respectively, Title IV of the 1990 Clean Air Act and the Ozone Transport Commission/NO x Budget Program.). Policymakers rarely see with perfect foresight what the appropriate emissions targets are to protect the public health and environment—the history is that these targets usually need to get stricter.
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.
As part the Israeli Ministry of Environmental Protection’s (MoEP’s) action plan to reduce pollution in Haifa Bay in Israel, Israel Police are actively enforcing exclusion rules that bar heavy vehicles in downtown Haifa Bay at certain times of the day. Air pollution, Haifa. —MoEP Director General Yisrael Dancziger.
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. LEVII criteria pollutant emission standards (PC/LDT1 and LDT2).
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.
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.
These incentives help to pay the difference between the cost of alternative-fuel vehicles and conventional vehicles. This will reduce county fleet operating costs and facilitate the county’s purchase of new CNG buses and vehicles. The county estimates the project will result in eventual fuel cost savings of $266,764 annually.
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.
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.
While it’s obvious that the internal combustion engine vehicles are polluting the air outside the buses, what you may not know is that numerous studies show that the pollution from the burning diesel regularly makes its way into the buses.
Simply put, the study found what advocates of electric transportation have long held to be true: as regards greenhouse gases and pollution generally speaking, the worst electricity is still better than petroleum. And the grid is getting cleaner and more renewable every year. I truly hope we have turned a corner.
Total cost of those five measures is estimated to be $3.9 NO x helps create ground-level ozone, or smog. Both pollutants are particularly harmful to children, the elderly and those who have preexisting health problems. billion, with $3 billion of that consumed by the new Tier 4 interstate line haul locomotives. Resources.
The main obstacles will be regulatory and, especially, environmental: Supersonic airliners could be hugely more polluting than their subsonic counterparts. But as was true for concerns about the ozone layer back in the 1960s, proponents of supersonic commercial aviation need to consider the deleterious effects of.
NIEHS goes on to say that air pollution is also linked to cancers, cardiovascular disease, respiratory disease, and other disorders. Local funding for electric school buses Federal government agencies are not the only ones providing funding for electric school buses.
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.
There is an exception to that in the category of what they call super pollutants, the very powerful but shorter-lived gases and chemicals that come from things like fertilizer production, methane. And so the cost of that right now is really, really high. So those are really important, and those are a little bit different.
In terms of travel time, the strike produced a net benefit to the system because the one-off time costs of the strike were less than the enduring benefits for this minority of commuters. One example where this strategy has been successfully employed is the Montreal Protocol on Substances That Deplete the Ozone Layer. military bases.
Although with many of these companies recast as diversified, greener “energy companies,” the extra pollution might not be the image they’re looking for. While recent EPA emissions rules for passenger cars and commercial trucks will help clean up particle pollution, ozonepollution remains a challenge.
