CARY, N.C. - Scientists meet this week in Cary to debate whether the Environmental Protection Agency's current standards for particulate matter and ozone air pollution are robust enough to protect public health.

The Clean Air Scientific Advisory Committee also will hear public testimony about the air-pollution standards.

John Bachmann, former associate director for science and policy at the EPA's Office of Air Quality Planning and Standards, said the agency reviews the standards for six air pollutants every five years.

"These standards for particulate matter were part of the original Clean Air Act, and they were established in 1971," he said. "They have been revised periodically, and they were revised in a big way in 1987 to change the definition of 'particulate matter' to just particles that you can breathe."

The committee also is accepting written comments. The EPA is expected to make a decision on changing the standards sometime next year.

Millions of Americans live in counties where breathing the air is linked to increased risk of lung cancer, early death and other health problems. Bachmann said particulate matter is so fine that there's no way to avoid inhaling it.

"EPA has previously determined there is a causal relationship between fine particles and mortality, hospital admissions and some other effects," he said.

Because of the Clean Air Act, Bachmann said, some regions have made noticeable improvements in air quality.

"I'll tell you, much of the eastern United States has seen a dramatic improvement in air quality, and if you look at pictures of what the sky look used to look like in Ohio - especially near the Ohio River Valley in the '80s - and compare it to today, there's no comparison," he said. "It's much, much better. I drive through there all the time."

An independent panel of scientists recently concluded that the EPA's current standard of 12 micrograms per cubic meter for fine particulates isn't enough to protect human health, but Bachmann predicts the EPA is likely to maintain that the current standards are sufficient.

Colorado is calling on solar energy entrepreneurs to put $156 million in Inflation Reduction Act funding to work accelerating rooftop and community-based solar installations, improving air quality, lowering energy bills and increasing energy independence.

Heidi Leathwood, climate policy analyst for the climate justice nonprofit 350 Colorado, said families living in apartments can connect to solar arrays built on top of parking lots and open spaces in other ways.

"If you're not able to put solar on your own rooftop, the community solar program will create large-scale solar gardens that you will be able to hook up to," Leathwood explained.

Solar garden subscribers can get significant discounts on their monthly electric bill. Developers creating the garden make money by selling energy to local utilities. Low-income residents can subscribe for free or at a steep discount. Firms interested in becoming a Solar for All program partner can connect through the Colorado Energy Office's website.

The program also offers low-interest loans and other incentives for income-qualified single and multifamily homes to cover upfront costs of installing solar. Leathwood added the program could fuel lots of new, good-paying jobs.

"To do the solar installation, to help with building the distribution and the transmission, and maintaining these facilities, maintaining the solar panels," Leathwood outlined.

The $156 million should be in Colorado coffers by October. Leathwood pointed out if fully implemented, the program could help more residents contribute to meeting Colorado's goals of producing 100% clean energy by 2040.

"Solar and wind energy are the cheapest way in the long run to reduce greenhouse-gas emissions," Leathwood stressed. "But if businesses, individuals and local governments don't work together to make sure all of that money gets spent, then it won't have the impact that it could have."

Forecasters are warning New Englanders to prepare for an "above-normal" number of hurricanes this summer.

Hurricane Beryl was already the strongest Atlantic hurricane on record for both June and July and brought damaging floods to the region last week.

Jhordanne Jones, climate scientist for the University Corporation for Atmospheric Research, said a cooling La Niña phase in the Pacific combined with a record warm Atlantic are creating dangerous conditions.

"When you have these very clear signals within the environment, it's clear that we're going to get a highly active hurricane season," Jones pointed out. "We know that from history."

She is referring to the 2020 hurricane season, which generated a record 30 named storms. The National Hurricane Center predicts up to 25 named storms this season, with four to seven major hurricanes by the end of November.

Scientists said most of the global warming attributed to climate change is taking place in the ocean. Sea surface temperatures in the North Atlantic have warmed to record levels since last spring and the Gulf of Maine is considered one of the fastest warming bodies of water on the planet.

Jones noted while hurricanes like Beryl may not take direct hits at New England states, the aftermath can be just as dangerous.

"The most intense storm doesn't always mean the most damage," Jones stressed. "It just needs to be the 'right storm' that dumps a lot of rain right over you and just will not dissipate in time."

Jones added storms can intensify even in unfavorable conditions as long as there is a warm ocean to fuel them and she encouraged people to be prepared.

Remnants of Hurricane Beryl washed away roads last week leaving people stranded in parts of Maine, New Hampshire and Vermont, where two people were killed when their car became submerged in floodwaters.

Clean air advocates are touting the benefits of electric vehicles in the wake of what they call "disinformation" from the U.S. petroleum industry.

The Environmental Defense Fund's advocacy partner EDF Action and representatives of public health and labor are talking with Pennsylvanians about the advantages of EVs in terms of price, performance and popularity, as well as public health and the environment.

David Kieve, president of EDF Action, said they're trying to arm people with the facts.

"If they're dealt a full set of facts, more and more Pennsylvania drivers will choose to make their next car an electric vehicle," Kieve contended. "It's our job to share those facts with folks, especially because there's so much misleading information out there."

Kieve said the American Petroleum Institute has funded an ad campaign "warning" consumers, without evidence, that the push to convert the U.S. to a "green economy" will force drivers to give up their internal combustion cars. Biden administration officials have called the claim false and misleading.

Kieve noted the cost of owning and operating an EV is decreasing and battery technology is becoming less expensive as well. The range for many EV models has also increased significantly. He added EV manufacturing in the U.S. has outpaced every other world region in recent years.

"More rapidly electrifying the vehicles that we choose to buy will help tremendously in cleaning our air and reducing greenhouse gas emission, which is driving climate change," Kieve argued. "And driving this heat wave we've been experiencing throughout the East Coast."

Edwin Hill, international business development representative for the International Brotherhood of Electrical Workers, said advances in battery technology are driving new sales.

"The batteries in the cars are improving tremendously," Hill emphasized. "They hold much more power, much more energy. And in turn, to charge those to that higher level of energy requires either more time or a higher charging rate."

The U.S. government and auto industry are investing billions of dollars in developing and manufacturing EVs, directly creating almost 200,000 new jobs.
