Op-Ed: How busy should Sonoma County’s airport be?

June 1, 2025

John Reid, PRESS DEMOCRAT

Flying out of Santa Rosa is relaxing. I love it too. But it is like a tiger cub. Cute now, and very likely to get out of hand.

I wasn’t aware of how many planes fly in and out of Charles M. Schulz-Sonoma County airport until they started flying over my house.

That happened in 2024 when the Federal Aviation Administration opened a new flight path over the western part of the county. From 2019 to 2024, the number of Santa Rosa airport passengers increased 58% to around 772,000 a year. Traffic increased 20% last year alone. On one recent weekday, there were 19 commercial departures and various private jets — including Ventura Air Services’ 4:37 a.m. flight to Cabo, which woke me up.

Airplanes pollute. No way around it. They account for 2.5% of global energy-related carbon dioxide emissions, and 9% of U.S. transportation emissions, which is our largest category. They emit nitrous oxides and fine particulates. Even gas cars pollute less than planes per passenger. And aircraft dump noise pollution across the landscape. People lose sleep. Bird communication is interrupted. Batteries are too heavy for planes, so the only way to make them “sustainable” is to fly them less.

Local legacy vs. big business in quarry quarrel

March 25, 2025

Martyn Lees, NORTH BAY BOHEMIAN

Pointing at the houses dotted around an aerial photograph of his property, Jonathan Trappe, a Forestville quarry owner and operator, indicated how close his family’s homes are to the asphalt plant he hopes to build on the quarry site.

“My father lives there, my brother lives there, I live here and our kids swim in that pond,” he said. All are within about a half square mile. He was speaking in reference to the community pushback the plan had elicited that cited environmental and fire risk concerns.

The point was clear, but Trappe added it anyway: “Who has more incentive to make sure this plant is safe?”

Tucked into the sweeping bends of Pocket Canyon Highway just outside of Forestville reside two stone quarries that serve western Sonoma County’s construction industries, most crucially the road repair sector. The quarries sit on either side of that stretch of scenic Highway 116, and both are surrounded by protected waterways and wildlife.

Op-Ed: The growing threat of the biomass energy industry

April 24, 2024

Take Action

Update – good news on legislation!

We need to understand the insidious, growing threat of the biomass energy industry, specifically forest-based bioenergy. Bioenergy turns forests into electricity, liquid biofuels, and fuel pellets for export on the international market. Touted as renewable, it is not clean, renewable or carbon neutral. It is devastating to human health and communities, to forests, watersheds, and wildlife habitat, and only worsens the climate crisis.

Golden State Natural Resources (GSNR) plans to build two massive fuel pellet processing plants in Tuolumne and Lassen counties, targeting 1 million tons of wood pellets per year for export, via the port of Stockton, to Europe and Asia. On June 30, 2023, 109 organizations, including scientists, doctors, environmentalists and others, wrote to GSNR vehemently opposing the project because of its potential impacts to climate, communities, and forests.

On February 28, 2024, GSNR ratified an MOU with the giant UK energy company Drax, the second largest biomass energy company in the world. Drax already runs 18 fuel pellet plants in the USA and Canada. Now it is targeting California, which has 33 million acres of forests.

In a shocking exposé of Drax in October 22, the BBC revealed that Drax is responsible for the destruction of millions of acres of mature and old growth trees in Canada and southeast USA. The company’s assertions that it uses only waste wood were proven to be false. Drax is by far the largest emitter of carbon dioxide in the UK. It is subsidized by UK taxpayers to the tune of around £1.4 billion (about $1.8 billion) in subsidies up until last year.

Northern California requires oil refiners to slash air pollution

July 21, 2021

Northern California regulators on Wednesday directed two of the state’s largest oil refineries to slash their fine particulate air pollution, which will require costly modifications at the plants.

The 19-3 vote by the Bay Area Air Quality Management District governing board means refineries in the area, including Chevron Corp’s (CVX.N) Richmond plant and PBF Energy Inc’s (PBF.N) Martinez refinery, will have to install wet gas scrubbers to reduce pollution spewed by their gasoline-making fluid catalytic cracking units (FCCU) within five years.

The new requirement is expected to cut PBF and Chevron’s particulate matter emissions from its cat crackers by about 70%, the air quality district estimates.

Cleaner air and racial justice versus jobs: The battle over fossil fuels hits the Bay Area

May 30, 2021

Joe Garofoli, SFGATE

Petaluma Mayor Teresa Barrett knew exactly what was going on when a coalition of multinational oil companies spent roughly $78,000 to support her opponents in her last re-election campaign.

That kind of cash stood out in a city where there is a $200-per-person cap on campaign donations.

Why would an oil-funded political action committee care about who held a part-time job that pays $40 a month? They went after Barrett because she represents Sonoma County as one of the 24 locally elected representatives who also serve on the Bay Area Air Quality Management District. “It was very clear that they didn’t want me on the air district board,” she said.

Barrett won re-election anyway in that 2018 race and remains on the air board, where another bruising political battle is being waged. And local officials who typically fly below the radar are being targeted again because they serve on a regional board that is far more powerful — and potentially influential to the rest of the country.

The fight is between forces who are usually united under the Democratic Party umbrella: It’s labor unions — siding with the oil companies who provide their jobs — against environmentalists and racial justice advocates.

Their standoff affects the air breathed by the 7 million Bay Area residents whom the air district is charged with protecting. But it is a complicated battle. And this disagreement in California previews the challenges facing America as it transitions away from fossil fuel — something both Gov. Gavin Newsom and President Biden have promised to do.

The proximate issue is a proposal coming before the air board on Wednesday. The proposed change would require refineries to install technology that greatly reduces the particulate matter they emit. It is a technology that, environmentalists point out, is already widely in use, including even in oil-friendly states like Texas.

If the board made those changes, it would not only reduce the number of particulates, according to the air district, but could literally save lives. The district has calculated that exposure to particulate matter from the Chevron refinery in Richmond increases mortality in the region by up to 10 deaths per year and up to six deaths per year from the PBF Martinez refinery.

Petaluma City Council moves to ban new gas stations

February 24, 2021

Kathryn Palmer, PETALUMA ARGUS-COURIER

The Petaluma City Council this week moved to ban new gas stations, cementing a nearly two-year moratorium as leaders accelerate ambitious climate action goals.

The prohibition, approved unanimously late Monday, caps a years-long effort by city leaders and climate activists who have pushed an ambitious, zero-emission-by-2030 timeline. The council must approve the ban during a second reading before it takes effect.

It also streamlines processes for existing gas stations seeking to add electric vehicle charging stations and potential hydrogen fuel cell stations, with city staff underlining an urgency to support alternative fueling in order to meet state zero-emission infrastructure targets.

“The goal here is to move away from fossil fuels, and to make it as easy as possible to do that,” Councilor D’Lynda Fischer said. “Right now, we have existing fossil fuel stations, and what we want them to do is add (electric vehicle) chargers and create another source of fueling people can use.”

The city of roughly 60,000 people is host to 16 operational gas stations, and city staff concluded there are multiple stations located within a 5-minute drive of every planned or existing residence within city limits.

A contentious Safeway gas station at McDowell Boulevard and Maria Drive, which drew the ire of residents for its proximity to a school and residential neighborhoods, will see no impacts from the ban.

The controversial project has been locked in a legal battle with resident group Save Petaluma since 2019. The group is suing Safeway and the city in an attempt to compel the company to complete an additional environmental study of the project, with the hope that the study will help block the fueling station first proposed in 2013.

Large methane leaks reveal long-standing shortfalls in oversight

December 21, 2020

Chiara Eisner, SCIENTIFIC AMERICAN

Ever since a father and son managed to draw four whiskey barrels of oil from a hand-dug hole near California’s Kern River 121 years ago, productive oil and gas wells have multiplied like mushrooms across the area. Though such wells are expected to emit minimal amounts of greenhouse gases during the oil-extraction process, scientists from a space-related research group were shocked by the size of the methane plumes they detected when they flew an infrared sensor over Kern County in 2015. Repeating the flights three more times in the next three years confirmed the initial reading: some wells were releasing at least six times more of the potent greenhouse gas into the atmosphere in one day than the Environmental Protection Agency had estimated they should emit in a year.

Karen Jones is one of the scientists at the Aerospace Corporation, the California-based nonprofit organization that conducted the aerial survey. She says she felt mystified by what she calls a lack of action among the oil fields’ operators and regulators as she watched the methane—the second-highest contributor to human-caused warming after carbon dioxide—continuously spew over the years. “The gas coming out of Kern County isn’t supposed to be there,” she says.

Revelations like Aerospace’s, which the nonprofit published in a report this past summer, are becoming more common. For years, oil and gas companies have been required to detect and repair methane leaks in their equipment. But scientists have produced dozens of studies over the past decade that suggest the current methods and technology used by industry to detect leaks—and by regulators to estimate how much methane is emitted—are inadequate to catch the actual scale of the problem.

Nonprofit groups and private satellite companies may soon make high-quality data about methane publicly available and ubiquitous, potentially creating more pressure to address the situation. Action to plug leaks and prevent further air pollution may be stymied in the meantime, though: the Trump administration took numerous steps that could weaken environmental protections, including rules outlining how companies monitor for and locate natural gas leaks in their equipment (methane is the main component of natural gas). Whether those rules will be reversed when the Biden administration enters the White House, and how long that process will take if it happens, remains to be seen.
