The Environmental Protection Agency is clamping down on methane emissions, and environmental groups say West Virginians' health will benefit.

Methane is the single largest greenhouse gas source in the United States, now generating more pollutants than the nation's shrinking coal industry. The regulations address natural gas processing and transportation, where the vast bulk of methane is released into communities.

Angie Rosser, executive director of the West Virginia Rivers Coalition, said the state has an especially high concentration of oil and gas wells, with more than half of residents living within a mile of a facility.

"These efforts to reduce methane will mean better air quality in our communities," Rosser contended. "Which means better health for our residents and also good news for reducing and slowing climate change."

Rosser added the new rules come at a time when the state faces increased risk of severe flooding. She noted communities near wells are at greatest risk of potentially costly and dangerous explosions and health effects of leaking methane. In a statement, the American Petroleum Institute said "to be truly effective, this rule must balance emissions reductions with the need to continue meeting rising energy demand."

Rosser added new technologies and third-party regulators tied to stricter methane regulation could expand West Virginia's job market.

"This rule also provides the potential to create new jobs in the state, that are needed," Rosser emphasized. "We're looking at how we can leverage this rule to create a whole new class of jobs that deal with methane mitigation."

According to the BlueGreen Alliance, made up of labor unions and environmental groups, more than 10,000 jobs could be created annually nationwide over the next decade with stronger efforts to curb methane emissions.

A bill to legalize cigar smoking in designated Montana barrooms has failed a third reading in the state House. Similar legislation is introduced most years, although polls show it is unpopular among Montanans.

The 2005 Montana Clean Indoor Air Act outlawed smoking in indoor public spaces and workplaces to reduce secondhand smoke and its negative health effects. Before the law passed, Helena happened to be a laboratory for those effects when a city ordinance outlawed public smoking for six months in 2002.

Richard Sargent is a retired family physician in Helena, who also volunteers with the American Heart Association. He said changes to air pollution rapidly affect health.

"We had all kinds of physiology studies showing the things that lead to heart attacks happen fairly rapidly with exposure to secondhand smoke," Sargent pointed out. "Thirty minutes is enough."

Sargent was the lead author of a study which found the rate of heart attacks in Helena decreased about 40%, from 40% to 24%, the year the ordinance went into effect.

Sargent noted the bill started with distinct buildings allowing cigar smoking outside of taverns and then changed to separate rooms in a shared building. He stressed there is no way to isolate airflow in such a setup.

"The American Society of Heating, Refrigeration and Air Conditioning Engineers has stated repeatedly that there's no ventilation system that'll handle secondhand smoke," Sargent added. "It just can't be done."

Among those surveyed, 77% of Montana voters oppose legalizing cigar smoking in bars and 89% support the Clean Indoor Air Act, according to an American Cancer Society poll.

As Cleveland tightens its air quality standards for the first time since 1977, health officials are urging residents to take simple steps at home to reduce their exposure to harmful pollutants.

The Environmental Protection Agency reported Americans spend about 90% of their time indoors, where air pollution levels can be two to five times higher than outdoor air.

Richard Stewart, public information officer of the Department of Public Health for the City of Cleveland, said the city's push is part of its efforts to engage local residents with new monitoring tools and resources through its "CLEANinCLE" initiative.

"A lot of folks don't realize small changes inside the home can really improve your quality of life," Stewart pointed out. "For example, taking your shoes off before you come in the house, checking for lead paint dust, cracking windows. Just regular cleaning can make a big difference in improved air quality in your house."

CLEANinCLE is a community air monitoring project, including sensors in multiple neighborhoods. The health department hosts two public meetings this week, one Wednesday from 6 p.m. to 7:30 p.m. at the Frederick Douglass Recreation Center and another on Thursday at the Community of Faith Assembly. Both events include free in-home air assessments and raffles for air purifiers and electric stoves.

While many cities face water-related lead risks, Stewart noted one of Cleveland's biggest concerns is still old paint. Officials are asking residents to look out for cracking or peeling paint surfaces, especially in older housing and report issues which could expose children to lead.

"There's no amount of lead that's acceptable in a child's bloodstream," Stewart emphasized. "If you see that 'alligator paint,' where it's cracking and kind of fizzling on the house, contact your landlord. And if you're not getting any results, contact us."

The city also has a Lead Hazard Control Grant Program to help eligible property owners remove lead paint.

A new study shows trees in mid-city Los Angeles absorb up to 60% of carbon dioxide emissions during spring and summer when the trees are most active.

In 2021, researchers from the University of Southern California placed 12 sensors in central L.A. to monitor carbon dioxide levels.

Will Berelson, professor of earth sciences, environmental studies and spatial sciences at the University of Southern California-Dornsife, said trees are surprisingly effective at lowering carbon dioxide levels in the air.

"The input of CO2 from cars is predicted to be a certain level," Berelson explained. "But when we look for CO2, we find much less. This difference is due to uptake of CO2 by trees."

Berelson pointed out emissions are like passengers on a train, as wind moves pollution through the city, where some get picked up and dropped off. The sensors measure the pollution in real time. The research published in the journal Environmental Science and Technology found trees absorb about 30% of carbon dioxide, averaged over 24-hour periods over a year. So clean energy, improved public transit and broader emissions reductions are still needed.

Berelson noted the sensors, called a Carbon Census Array, will track carbon dioxide levels for years to come.

"The City of L.A. is always committed to reducing emissions and it isn't clear how they're going to keep track of whether their emissions have actually lowered or not," Berelson observed. "But we've got a way to now track emissions and quantify emissions."

The sensor network is now being expanded, with 12 additional sensors reaching out to Santa Monica on the west side of the city.
