Harley-Davidson to pay $15 million for cheating on clean air rules

Et tu, Harley-Davidson?

Court settlement includes mitigation and buy-back program

Staff Report

Volkswagen isn’t the only company to try and circumvent clean air rules. This week, Harley-Davidson agreed to pay a $12 million civil penalty for installing illegal devices that increase air pollution from their motorcycles.

Under the court-approved settlement, the company also agreed to spend $3 million to mitigate air pollution by replacing older wood stoves with cleaner heating units, and to  stop selling and to buy back and destroy the so-called super-tuners.

According to court documents, Harley-Davidson manufactured and sold about 340,000 of the devices, that, once installed, caused motorcycles to emit higher amounts of certain air pollutants than what the company certified to EPA. Aftermarket defeat devices like these super tuners alter a motor vehicle’s emissions controls and are prohibited under the Clean Air Act for use on vehicles that have been certified to meet EPA emissions standards.

Study quantifies role of oil and gas emissions in ozone formation along Colorado Front Range

Research to help shape efforts to reduce dangerous air pollution

Emissions from oil and gas production along the Colorado Front Range are a significant, measurable part of the region’s chronic summer ozone problem, scientists concluded after taking a close look at air pollution during an extensive research project in the summer of 2014.

Ozone levels in the area often spike above 70 parts per billion, a level deemed by the EPA to be dangerous to human health and to the environment, causing respiratory problems and damage to plants. About 17 ppb of that ozone are produced locally; about 3 ppb come from oil and gas industry emissions, according to a new study, published in the Journal of Geophysical Research.

The researchers said their findings could help shape efforts to improve air quality in the region. Along with the volatile organic compounds released from oil and gas operations, nitrogen oxides from cars, buses and trucks are also a big factor. Any meaningful effort to improve air quality will have to address both sources. Continue reading “Study quantifies role of oil and gas emissions in ozone formation along Colorado Front Range”

Colorado just can’t get a grip on its smog problem

State  fails to meet EPA standard set to protect public health; ozone problems to worsen with global warming

The modest steps taken by Colorado to try and improve air quality along the Front Range aren’t enough, according to the EPA. This week, the federal agency said the state has failed to meet air quality standards set to protect public health.

In a Federal Register Notice, the EPA designated the Denver-Boulder-Greeley-Fort Collins-Loveland corridor as a nonattainment area because it didn’t meet the federal limits for ground-level ozone, the key ingredient of smog. Under the Clean Air Act, the state was required to bring the Front Range into compliance with smog limits by July of 2015.  Colorado failed to meet this deadline.

Global warming will lead to spike in ozone pollution

Along with catastrophic heatwaves, flooding and droughts, greenhouse gas emissions are likely to result in a big spike in the number of days when air quality is impaired by ozone, according to a new study from the Harvard John A. Paulson School of Engineering and Applied Sciences.

Left unchecked, global warming could lead to between three and nine additional days per year of unhealthy ozone levels by 2050, the researchers found.

“In the coming decades, global climate change will likely cause more heat waves during the summer, which in turn could cause a 70 to 100 percent increase in ozone episodes, depending on the region,” said Lu Shen, first author and graduate student at SEAS.

Environment: EPA faces ozone lawsuit

Toxic haze kills millions worldwide

Staff Report

There’s little question that air pollution is one of the biggest killers on the planet. Some recent estimates place the number of global deaths attributed to airborne toxins anywhere between 3.3 to 7 million per year, and that number is expected to go up by 15 to 20 percent in the next few decades.

And while countries with developing economies like China and India have the biggest problems, the U.S. is not immune from poisonous pollutants, especially invisible ozone. In some parts of the country, ozone pollution is getting worse, not better. The EPA has tried to tackle ozone pollution by setting new standards, but faced resistance from industrial polluters.

As a result, watchdog groups say the agency has fallen short, and the Center for Biological Diversity says it will sue the EPA because 17 states and the District of Columbia have failed to reduce ozone pollution, which poses serious threats to public health, wildlife and ecosystems. Essentially, environmental activists say the EPA has failed to meet standards set under the Clean Air Act. Continue reading “Environment: EPA faces ozone lawsuit”

Distant wildfire smoke may raise ozone levels

Across the U.S., ozone levels were higher on smoky days than on smoke-free days

Staff Report

Wildfire smoke on its own can trigger health warnings for direct exposure, and new research from Colorado State University suggests that there may be a more widespread impact after they linked smoke with elevated levels of ozone.

In globally warming world, where the number and size of wildfires keeps growing, the findings have significant implications for public health. Continue reading “Distant wildfire smoke may raise ozone levels”

EPA sets new ozone standard but faces challenges

Got smog? EPA wants to cut ozone, but will face a challenge on new standard.

Environmentalists say new rule is to weak; industry asks Congress to step into the fray

Staff Report

The EPA’s new smog-fighting ozone standard is likely headed down the same path as the agency’s other recent initiatives to improve the environment.

Like the recently updated wetlands rule and the Clean Power Plan, the new ozone limit was immediately criticized from all sides. Environmental advocates said the agency ignored its own experts when it set the new limit at 70 parts per billion. Industry claims the new rule will cut profits and cost jobs.
