Wildfire Crews Race to Keep Fierce California Blaze From Former Nuclear Reactor Site – Inside Climate News
WEST HILLS, Calif.—Her gray SUV packed and a fire-proof bag ready, Melissa Bumstead didn’t waste any time Monday as plumes of smoke engulfed the sky near her suburb.
Most neighbors in West Hills—about 30 miles west of downtown Los Angeles—stayed put after only a voluntary “evacuation warning” was issued for the area. But not her.
As the ever-growing Sandy Fire swept across Southern California, the 45-year-old mother could only think of one thing.
Bumstead lives less than four miles from the site of possibly the worst nuclear meltdown in U.S. history besides the Three Mile Island accident.
The Santa Susana Field Laboratory, or SSFL, is known locally as a problem site—with a pockmarked history amid a spotty cleanup. A blaze hitting the former nuclear reactor and rocket testing site, Bumstead is sure, would be a cataclysm.
“This is what it looks like to evacuate when you’re scared,” she said Monday, “because if the smoke were to be radioactive or toxic, you don’t want to breathe it.”
Bumstead returned home Tuesday but remains on alert as the Sandy Fire rages on.
The fireline was about a quarter-mile from the site on Tuesday morning. Boeing—which has owned SSFL since 1996—said it has evacuated all personnel from the site who are not involved with fire control.
“We are actively monitoring the Sandy Fire near the Santa Susana site and are in close coordination with local authorities and emergency responders,” a Boeing spokesman told Inside Climate News in an email.
“This is an ongoing situation, and as it evolves, we will continue to monitor fire conditions,” he said, deferring to the state for other questions.
Radiation exposure has short-term as well as long-term impacts, including greater risk of developing cancer and possible harms to cardiovascular and immune systems.
The Sandy Fire, which surpassed 1,300 acres on Tuesday with only 5 percent containment based on early response efforts, burned near Simi Valley.
More than 33,000 people in the valley and other communities were placed under evacuation orders. At least one home has been destroyed as of Tuesday afternoon. The cause remains under investigation.
Fire crews made strides in cutting firelines since Monday morning, when the incident first began as a brush fire. At about 4 p.m. Pacific on Tuesday, prevailing winds shifted direction from the west, fueled by out-of-season Santa Ana winds.
The shifting conditions placed the Santa Susana Field Lab in the immediate path of the Sandy Fire—raising alarms from nearby families like Bumstead’s.
Fire crews raced to the scene.


“That is an area that we’re trying to keep the fire out of and we’re putting multiple dozer lines in place, as well as our hand crews are working to increase containment and build contingency lines,” Andy VanSciver, a firefighter and spokesman for the Ventura County Fire Department, told Inside Climate News on Tuesday.
VanSciver said first responders were at the former nuclear site “right away.”
The state Department of Toxic Substances Control did not immediately provide comment Tuesday afternoon.
The U.S. Department of Energy said in a statement online that it “is closely monitoring the Sandy Fire located adjacent to the Santa Susana Field Laboratory.” So far, “there is no impact to the site,” the agency wrote.
VanSciver said he was confident the community would be protected as the fire department arrived at the site quickly, but noted that updates will be provided online.
Not the First Wildfire Threat
Peter Hemken paused Monday night on his walk up the steep Sequoia Avenue in Simi Valley, overlooking a ridge covered in gray smoke.
What began as a small cluster of fires from his sight line became a full out strip.
“Oh my God, that’s really flaring up,” the 73-year-old remarked, pulling out his phone for a photo.
Every hour or so since Monday morning, Hemken joined others in walking up the hill to see the Sandy Fire’s progress.
“I used to work in engineering up at Rocketdyne,” he said of the nearby facility that developed space shuttles.
A Simi Valley resident for over two decades, Hemken was well aware of the Santa Susana Field Lab. Residents of his Simi Valley neighborhood have not had to evacuate because of a wildfire in recent years, but they are always ready to. The lab has something to do with it.
“I would hate to see a fire get up there,” he said, pointing toward the SSFL site. “There’s still a lot of nasty chemicals up there.”
The SSFL cleanup plan is still being finalized, having been expanded, and then stalled, several times in the last 20 years. Through interim measures, approximately 6,000 cubic yards of the most contaminated soil was removed in 2024, the year excavation began and the only one with data available. But that cleanup was limited to a single area. The scope of the full remediation is still being decided by the state, federal authorities and Boeing.
The Sandy Fire on Tuesday encroached uncomfortably close to the former nuclear site’s north buffer zone, according to residents and a perimeter map of the area’s burn zone.
Melissa Bumstead said health concerns surrounding the site are personal to her. Her daughter, Grace, has had two bouts of a rare form of leukemia, which the family believes is linked to the radiation from SSFL.
She began campaigning 12 years ago for a complete remediation of the former nuclear test site soon after her daughter’s cancer diagnosis.

“It was considered an urban legend,” Bumstead said of cancer links to the site. “It wasn’t until [my daughter] got diagnosed that we started doing research and found out … there were a bunch of studies by the University of California, Los Angeles, and epidemiological federally funded studies.”
As it turned out, “the research was there. It just wasn’t being communicated,” she said.
One of the reports that pushed Bumstead toward founding her advocacy organization, Parents Against Santa Susana Field Lab, was a 2007 study led by Hal Morgenstern for the Agency for Toxic Substances and Disease Registry and the Centers for Disease Control and Prevention.
Morgenstern, an epidemiologist at the University of Michigan, found residents within two miles of SSFL face a 60 percent higher rate of certain cancer diagnoses than those living five miles away.
That study—though not enough to label SSFL as the cause of the higher cancer rate—shed light on the strong correlation between proximity to the site and cancers triggered by radiation exposure.
That’s why residents worry whenever air quality alerts start to ping on their phones and a wildfire approaches.
It happened in 2018.
The Woolsey Fire burned through 80 percent of the SSFL site, though most of the affected area was in the southern buffer zone and in the rocket testing area, not the nuclear testing area.
Initially, the state Department of Toxic Substances Control assured the community that there was no risk of radioactive contamination, an assertion that the agency seemingly confirmed in the 2020 Final Report on the Woolsey Fire.
However, an independent study looking at 360 samples from the area surrounding the burn zone found that 3 percent contained radioactive particles that could be traced to the SSFL. The study, conducted by a doctoral student at Worcester Polytechnic Institute and the co-founders of nuclear watchdog group Fairewinds Energy Education, analyzed more than 10 times the samples taken by the state for monitoring.
Boeing had no immediate comment when the study was released in 2021, issuing a statement to NBC4 in Los Angeles that said: “Cleanup at Santa Susana will continue to follow California law… The transformation of Boeing’s land at Santa Susana from a field laboratory to open space is well underway.”
In 2023, Boeing released the results of a study by Risk Assessment Corporation (RAC) that it funded. “Based on the soil sampling, we found no evidence of SSFL impact in off-site soils as a result of the Woolsey fire,” the study says. “Moreover, we found no radionuclide impact on the off-site soils we sampled from past operations of the SSFL”
Parents Against the Santa Susana Field Laboratory responded on its website: “Boeing redid the Woolsey Fire study…collecting samples nine months after the fire. We collected our samples within a month. Our study was peer-reviewed by independent scientists. Boeing’s scientists were paid by Boeing and their findings were NOT peer-reviewed.”
Bumstead received training and volunteered to collect samples for the independent study, along with the co-director of Parents Against SSFL, Jeni Knack.
Bumstead was glad to be able to be a part of that research and hopes their findings of scattered radioactive material up to nine miles away from the lab will add pressure for better monitoring this time.
“We have such a deeply ingrained belief that if it wasn’t safe, the government wouldn’t let us live here,” she said of local residents. After her experience with the Woolsey fire, she said, she knows that is not always the case.
Although the Sandy Fire has not reached the grounds of the SSFL as of now, it has burned “concerningly” close to the site of the 1959 sodium reactor meltdown, according to one former firefighter with CAL FIRE who asked that his name not be used.
He recommended residents seal off living areas and create positive pressure in their homes by turning on fans and using air filters. The radiation is contained in dust and ash particles, he said, so the sooner you wipe everything down and wash them away, the lower your risks of exposure.
People in Simi Valley said they are taking such measures but thinking of the long term, too. As wildfires grow fiercer due to man-made climate change, infringing on more homes and more people, Bumstead fears what ferocious winds and massive blazes could do.
“There’s a twisted joke that we have here that the Santa Susana Field Lab will be cleaned over time, because all of it will blow off into the surrounding communities,” said Bumstead. “The surrounding communities will be contaminated, but the site itself will be clean.”

Tom Steyer Wants to Save California From Billionaires. But Also Doesn’t Want Them to Leave
For those concerned about the influence of Big Tech and billionaires on California’s future, Tom Steyer looks like an obvious choice. A billionaire who amassed his fortune after founding Farallon Capital Management, one of the world’s biggest hedge funds, Steyer quit the firm in 2012 and turned to philanthropy, political advocacy, and climate activism, among other pursuits. Now, he’s jostling for position among a handful of Democratic and GOP candidates looking to advance from a June primary and then win the California governorship this November.
Ahead of the midterms, I’m talking to candidates relevant to WIRED’s interests: A few weeks ago I spoke with Alex Bores, a candidate for New York’s 12th Congressional District, whose history as a Palantir employee and stance on AI regulation has attracted the ire of Silicon Valley–backed super PACs.
Steyer felt like the next obvious choice for a conversation: He’s running to lead a state where issues like AI, immigration enforcement, and climate change, among other core WIRED subjects, are paramount. Steyer’s posture in the race is also unique. He’s been described as a “class traitor” for ostensibly eschewing his fellow elites, voiced support for California’s controversial Billionaire Tax Act—which has everyone from Sergey Brin to Peter Thiel either making moves to or threatening to flee the state—and campaigned hard on affordability, climate policy, and the promise that he’s immune to corporate influence. (As a billionaire spending more than $130 million on his own gubernatorial campaign, I certainly hope he would be.)
As I said, for some Democratic voters, Tom Steyer seems to check a lot of boxes. Then he starts talking.
Steyer is adept, as politicians usually are, at toeing the line. But the line, in politics generally and California specifically, seems to be the problem: Steyer, or whomever is elected to the governorship this November, will be walking an exceedingly thin one. Taxing California’s billionaires without alienating them. Getting a grip on the state’s AI development without throttling it (or, again, alienating the billionaires building it).
I could feel Steyer’s reluctance to come down too firmly or dig in too deeply on issues, maybe to avoid alienating any potential voting block. Which made me wonder: Can Tom Steyer be a pro-billionaire governor who also taxes the hell out of them? Can he rave about the “mind-blowingly amazing” advances in AI while bringing the industry to heel? Can he learn the name of WIRED’s global editorial director (me) before she interviews him?
The third question is answered in the interview. The former two will be formidable challenges for anyone elected to California’s governorship—and I didn’t leave our conversation convinced that Steyer’s posture is a particularly coherent one. The minimum requirement for a California governor might be the ability to use Google.
This interview has been edited for length and clarity.
KATIE DRUMMOND: Welcome, Tom, thank you for joining us on The Big Interview.
TOM STEYER: Kate [sic], thank you for having me.
So, you’re a billionaire. You made your money in the hedge fund world. But now, in the last decade-plus, you’ve become a climate activist. Tell us about that transformation.
When I was growing up, when I got free time, either from school or work, I tried to go to wild places and get outdoor jobs. I worked as a ranch hand, I worked picking fruit. Before I went to business school, I spent the summer in Alaska, and I went to Alaska because I wanted to see what North America looked like before Europeans showed up.
I wanted to see the animals, I wanted to see the birds, I wanted to see the fish, I wanted to look at Denali. I wanted to see what it looked like, vast untracked North America, rich and fertile.

$6 gas and refinery fears collide with California’s climate ambitions
By Alejandro Lazo, CalMatters
This story was originally published by CalMatters. Sign up for their newsletters.
California is considering handing oil refineries and other major polluters billions of dollars in free emission allowances just as the state says carbon reductions need to come faster than ever.
In the last six months, two refineries have closed and gas prices have topped an average of $6 a gallon as the Iran-Israel war sent oil markets into turmoil. The oil and gas sector spent $10.3 million lobbying Sacramento in the first three months of the year, according to lobbying filings, with the Western States Petroleum Association and Chevron accounting for the bulk of it.
The result is a new proposal before the California Air Resources Board that would provide as much as $4 billion in new free emission permits to companies with half slated for the fossil fuel industry in exchange for commitments to invest in clean energy.
Environmentalists warn the proposal is a giveaway to Big Oil that would weaken California’s “cap-and-invest” program just as the state is relying on it to cut emissions and fund climate, housing and other programs. Anthony Martinez, a spokesman for Gov. Gavin Newsom, said the changes are necessary to keep the state’s carbon market “durable” and “affordable” amid mounting refinery closures.
The fight over California’s carbon market has exposed the political tensions at the heart of Newsom’s energy transition agenda. California is trying to preserve its climate ambitions while keeping gasoline affordable for drivers already facing the highest prices in the country. Critics say the air board’s proposal accomplishes neither goal.
“We are really concerned that this would significantly kneecap the program,” said Chloe Ames, a policy adviser with NextGen Policy.
Weakening the backstop
Through California’s 13-year-old carbon market, major polluting companies must buy permits for every ton of greenhouse gases they emit, with the state capping total emissions year by year. Each permit is worth real money and companies can sell the ones they don’t use. The program is considered California’s climate backstop — the only state policy that sets a firm limit on greenhouse gas emissions.
At the heart of the dispute with environmentalists is a proposed subsidy program carved out of that carbon market. The air board, if it approves the proposal on May 28, would create a new pool of free pollution permits for refineries, cement plants and other big companies that pledge to invest in clean energy and efficiency projects.
The pool would be capped at 118.3 million permits — the same number the air board has said must come off the market for California to hit its 2030 climate target. Environmentalists say the proposal risks wiping out those reductions.
Berkeley energy economist Meredith Fowlie, who chairs an independent committee that oversees the carbon market, wrote in a recent analysis that the design would give qualifying refineries more free permits than they need to cover their emissions.
“One could use the word generous,” Fowlie said.
Rajinder Sahota, the air board official overseeing the program, said the proposal would ensure emissions reductions. The new permits, she said, would only go to companies undertaking clean energy and efficiency projects and would be limited, temporary and rescinded if companies misuse them. The plan is meant to help keep refineries operating in California at a time of uncertainty, she added.
“We want to make sure that there’s reliable, affordable fuel for California consumers while the demand persists,” Sahota said.
But environmentalists say the air board has built in almost no accountability for how companies invest in those projects. Katelyn Roedner Sutter, state director for the Environmental Defense Fund, said the proposal “is based on proposed investment, not any guaranteed reduction.”
“That’s a red flag,” she said.
A climate money crunch
Quarterly auction revenue for state programs could drop from roughly $4 billion a year to about $2 billion under the proposal, according to the Legislative Analyst’s Office.
Sen. John Laird, the state Senate budget chair and a co-author of California’s original 2006 climate law, warned at a May 6 hearing that the proposal “flies against many things we negotiated just last fall” with the governor and could put the carbon market deal “back on the table.”
Not all lawmakers are critical. Assemblymembers Jacqui Irwin and Cottie Petrie-Norris, who respectively chair climate and energy committees, said the proposal “reflects the Legislature’s focus on affordability,” and urged the board to proceed “without delay.”
They pointed to an increase in the Climate Credit, the twice-yearly rebate that the carbon market funds on Californians’ utility bills; a UC Santa Barbara analysis, however, found the new subsidy could shrink the credit by as much as $1.7 billion under the proposal.
A separate, bipartisan group including Assemblymember David Alvarez, a Democrat, and Senator Suzette Valladares, a Republican, argues the purpose of the carbon market is to cut emissions, not raise money for programs.
Newsom struck an eleventh-hour deal with lawmakers last year that extended the state’s carbon market through 2045 and set the order of which state programs get auction money first.
Under that plan, California’s high-speed rail project receives $1 billion a year before many other programs. Lawmakers also carved out a $1 billion annual pool for priorities they control themselves, but Newsom in January proposed committing that money to wildfire spending and other programs.
Last in line are programs lawmakers have spent years building into California’s climate agenda: affordable housing and transit-oriented development meant to reduce driving and climate pollution, rail and bus service, wildfire resilience, clean drinking water in poor communities and neighborhood pollution monitoring.
Newsom unveiled a revised state budget on May 14 that did not reflect the potential drop in carbon market revenue. Laird, in an interview, said the administration told him the revenue drop wouldn’t show up in the coming fiscal year.
Laird said he planned to “ground truth” that assessment in the weeks ahead. The hit “would still be a big hit the year after this budget year,” he added.
Big Oil’s biggest target
California’s carbon market became a central focus of the oil industry’s lobbying efforts after the air board released a January proposal sharply reducing free pollution permits for industry.
Seven of the 10 highest-spending oil and gas lobbying groups in California pushed state officials on the proposal, state filings show. The petroleum association and Chevron mounted some of the industry’s most aggressive lobbying, pressing lawmakers, the governor’s office, the air board and the California Energy Commission on the plan.
The April plan raised free permits for most industries through 2030 above the January version, but deferred decisions on permits after 2030 to a future rulemaking.
Jim Stanley, a spokesman for the petroleum association, said the group has been pressing lawmakers, regulators and the governor’s office about “the potential consequences of a poorly structured cap-and-invest program.”
Chevron spokesman Ross Allen declined to comment beyond letters Chevron filed with the air board. Chevron initially warned the proposal threatened refinery survival in California. After last month’s revisions, the company is continuing to push for additional protections.
Zach Leary, a lobbyist for the petroleum association, said California needs to go further than even its latest proposal. He wants California to lock in a higher level of free permits permanently.
“The state is acknowledging that affordability and ambition are not getting along very well right now,” Leary said.
Eddie Ahn, executive director of Brightline Defense, oversees community air sensors in San Francisco’s Tenderloin, Mission and South of Market neighborhoods funded through the state’s community air protection program. That program is among those that could lose state money if carbon market auctions decline under the proposal.
“If the funding is cut off, then convening groups of people on a monthly basis — that goes away,” Ahn said. “It means frontline communities get disconnected from environmental policy.”
