The Brief

California’s last nuclear power plant was given approval to stay open Tuesday while regulators decide if the its lifespan can be extended for another five years.

Pacific Gas and Electric, which operates the Diablo Canyon Power Plant, submitted a license renewal application to federal nuclear safety regulators last month at the state’s direction. The application was in anticipation of last week’s California Public Utility Commission’s vote to keep Diablo Canyon’s two reactors operational until 2029 and 2030, respectively.

About Diablo Canyon

Diablo Canyon is the state’s largest power plant and clean energy producer, generating enough carbon-free electricity to meet the needs of 3 million residents, according to PG&E.

The plant sits on about 1,000 acres along the Pacific Coast between Morro Bay and Pismo Beach in San Luis Obispo County, and provides nearly 9% of the state’s electricity supply.

Diablo Canyon has two reactors that are currently licensed to operate into 2024 and 2025.

However, Gov. Gavin Newsom signed legislation last September that authorized a short-term extension of the plant’s license. In a letter to the state senate, Newsom said keeping Diablo Canyon operational will help California meet its energy reliability needs.

That decision was met with pushback from environmental groups like Friends of the Earth, who believe the nuclear power plant poses “tremendous and unnecessary” risks, according to their website.

“Diablo sits near multiple active earthquake faults, posing an unacceptably high seismic disaster risk,” Friends of the Earth said in an open letter to state lawmakers.

However, PG&E maintains that the plants are safe and can withstand earthquakes, tsunamis and flooding.

The utility said it will also conduct an updated seismic assessment of Diablo Canyon and submit the results to the California Public Utilities Commission as part of the legislation Newsom signed.

But any new retirement date for the plant ultimately requires approval from federal, state, and local regulators.

State energy officials

Newsom’s signature also meant the California Public Utilities Commission had to vote on extending the lifespan of Diablo Canyon.

During their Dec. 14 meeting, Commissioner Karen Douglas said that requirement is a recognition of the importance of this plant, specifically how it can help the state tackle reliability challenges as it transitions to clean energy.

“Including the weather and climate extremes that we have experienced, uncertainties and timing of getting needed resources online, and the cost challenges that we face in scaling up the clean energy transition so quickly,” she said.

Douglas called the extension an opportunity to help bridge some of the early years, but she said it’s incredibly important officials don’t count on another extension for Diablo Canyon.

The commissioners reviewed the plant’s cost effectiveness, considered the price and process for extended operations, and looked at how to distribute the benefits of it being up and running for another five years.

The California Public Utilities Commission approved the extension in a 3-0 vote, with Commissioner Darcie Houck abstaining and Commissioner Genevieve Shiroma absent.

What’s next for the power plant

With the state’s support, the Nuclear Regulatory Commission is reviewing PG&E’s license renewal application for Diablo Canyon. However, that process is expected to take several years, so federal regulators are allowing Diablo Canyon to continue operating while the application is reviewed.

PG&E said there will be opportunities for public participation during that time. Additionally, if you believe you would be “adversely affected” by the renewal, you can request a formal adjudicatory hearing, according to the NRC.

As Los Angeles homeowners grapple with the expense of rebuilding after last year’s devastating fires, an L.A. City Councilmember is putting forward an idea that could lower some costs.

Councilmember Traci Park, who represents the Pacific Palisades, has introduced a motion to explore waiving part of the city’s portion of the local sales tax for fire victims who purchase rebuilding materials in the city.

The 1% of the local 9.75% sales tax that goes into the city’s general fund would be given back to consumers under the proposal. The waiver could apply to lumber, appliances and other rebuilding goods purchased within the city.

The motion, introduced Friday by Park and seconded by Councilmember John Lee, says: “The City should do everything within its power to alleviate the financial burden for these residents and businesses in order to facilitate their return and stabilize the Pacific Palisades community.”

Would it make much of a difference? 

Economists told LAist the proposal could help many homeowners mitigate the high cost of rebuilding, but likely wouldn’t tip the scales for under-insured, under-resourced property owners.

“It wouldn't hurt if it's very well designed and easy to use,” said Alexander Meeks, a director at the Santa Monica-based Milken Institute. “But I'm not sure if it's really going to tackle the scale of the financial challenge that survivors are facing.”

Meeks noted that the tax waiver wouldn’t lower up-front costs such as environmental testing, architectural design and permitting. And it may not help homeowners sourcing raw materials from outside the city.

Zhiyun Li, a UCLA Anderson School of Management economist, said the waiver could help some homeowners justify the additional cost of rebuilding more fire-safe structures.

“Homeowners must typically pay out of pocket to upgrade to IBHS+ standards, which are more stringent,” Li said. “The tax waiver could encourage upgrading to IBHS+ standards or investing more in mitigation, thereby reducing future risk and improving the likelihood of maintaining insurance coverage.”

What’s next for the proposal? 

The proposed tax relief would not be available to properties that have been sold since the fires started in January 2025.

The motion has been sent to the City Council’s budget and fire recovery committees. If approved by the full council, it would require the city administrative officer, the Office of Finance and the city attorney to report back to the council within 60 days on options for crafting a tax relief plan.

The motion calls for the report to consider factors such as how to minimize the burden of administering the tax relief, what documentation homeowners would have to submit and what it would cost the city to oversee the program.

Senate and House Republican leadership have resurrected a stalled plan to fund the Department of Homeland Security after a record 47-day funding lapse.

House Speaker Mike Johnson, R-La., and Senate Majority Leader John Thune, R-S.D., said in a joint statement on Wednesday that the House will take up a measure passed by the Senate last week to fund most of DHS except Immigration and Customs Enforcement and Border Patrol through the end of September.

Republicans would then attempt to fund ICE and Border Patrol for three years using a party-line budget reconciliation bill that would not require support from Democrats.

"In following this two-track approach, the Republican Congress will fully reopen the Department, make sure all federal workers are paid, and specifically fund immigration enforcement and border security for the next three years so that those law-enforcement activities can continue uninhibited," Thune and Johnson wrote.

The agreement comes nearly a week after House Republicans dismissed an identical plan, refusing to take up the Senate-passed measure and instead passing a 60-day short term funding bill for all of DHS that had little chance of overcoming Democratic opposition in the Senate.

Johnson called the agreement a "joke" and President Donald Trump declined to publicly endorse the deal. Trump had previously resisted any package that did not include his push to overhaul federal elections known as the Save America Act.

"I think any deal they make, I'm pretty much not happy with it," Trump told reporters last week.

Democrats welcomed the agreement as in line with their pledge not to give ICE any more money without reforms after immigration enforcement agents killed two U.S. citizens in Minneapolis. But the deal does not include any of the policy demands Democrats are pressing for, such as a ban on masks for immigration enforcement officers and requiring warrants issued by a judge, not just the agency, to enter homes.

"For days, Republican divisions derailed a bipartisan agreement, making American families pay the price for their dysfunction," Senate Minority Leader Chuck Schumer, D-N.Y., wrote in a statement Wednesday. "Throughout this fight, Senate Democrats never wavered."

Trump seemed to bless the revived plan earlier Wednesday, writing on social media that he wants a party-line bill to fund immigration enforcement on his desk by June 1.

"We are going to work as fast, and as focused, as possible to replenish funding for our Border and ICE Agents, and the Radical Left Democrats won't be able to stop us," Trump wrote.

Despite the shutdown, ICE has been minimally impacted because Republican lawmakers approved $75 billion for ICE through another party-line budget reconciliation bill last year.

Congress is on a two-week recess, but the Senate and House could move to fund all of DHS except ICE and CBP as early as Thursday using a procedure known as unanimous consent that allows the chambers to circumvent formal voting as long as no member objects.

Even during a recess when most members are not in Washington, this could be unpredictable, especially in the House, where many hard-line conservatives oppose a deal that does not fully fund DHS.

"Let's make this simple: caving to Democrats and not paying CBP and ICE is agreeing to defund Law Enforcement and leaving our borders wide open again," Rep. Scott Perry, R-Pa., a member of the ultra-conservative House Freedom Caucus, wrote on X. "If that's the vote, I'm a NO."

If a member does object, that could require waiting for another vote when all members are back from recess.

California clocked its second-worst snowpack on record Wednesday, a potentially troubling signal ahead for fire season.

It’s an alarming end to a winter that saw abnormally dry conditions briefly wiped from California’s drought map in January, for the first time in a quarter-century.

Though precipitation to date has been near average, much of it fell as rain rather than snow. Then March’s record-breaking heat melted most of the snow that remains. The state’s major reservoirs are nevertheless brimming above historic averages and are flirting with capacity, and a smattering of snow, rain and thunderstorms are dousing last month’s heat wave.

But experts now warn that California’s case of the missing snowpack could herald an early fire season in the mountains.

On Wednesday, state engineers conducting the symbolic April 1 snowpack measurement at Phillips Station south of Lake Tahoe found no measurable snow in patches of white dotting the grassy field.

“I want to welcome you call to probably one of the quickest snow surveys we’ve had — maybe one where people could actually use an umbrella,” joked Karla Nemeth, director of the California Department of Water Resources. “We’re getting a lot of questions about are we heading into a hydrologic drought? The answer is, I don’t know.”

State data reports that California’s snowpack is closing out the season at an alarming 18% of average statewide, and an even more abysmal 6% of average in the northern mountains that feed California’s major reservoirs.

Only the extreme drought year of 2015 beat this year’s snowpack for the worst on record, measuring in at just 5% of average on April 1st, when the snow historically is at its deepest.

“I think everyone's anticipating that it will be a long, busy fire season,” said Lenya Quinn-Davidson, director of the UC Division of Agriculture and Natural Resources Fire Network.

“Without a snowpack, and with an early spring, it just means that there’s much more time for something like that to happen.”

‘It’s pretty bizarre up here’ 

In the city of South Lake Tahoe, which survived the massive Caldor Fire in the fall of 2021 without losing any structures, fire chief Jim Drennan said his department is already ramping up prevention efforts.

“It's pretty bizarre up here right now. It really seems like June conditions more than March,” Drennan said. “People are already turning the sprinklers on for their lawns.”

Without more precipitation, an early spring may complicate prescribed burning efforts. But Drennan said fire agencies in the Tahoe basin can start mechanically clearing fuels from forest areas earlier than usual.

“That means we can get more work done,” he said.

It also means homeowners need to start hardening their homes now, said Martin Goldberg, battalion chief and fuels management officer for the Lake Valley Fire Protection District, which protects unincorporated communities in the Lake Tahoe Basin’s south shore.

Goldberg urges residents to scour their yards for burnable materials, create defensible space and reach out to local fire departments with questions. The risks are widespread — from firewood, wooden fences, gas cans, plants, pine needles — even lawn furniture stacked against a house.

“In years past, I wouldn't even think of raking and clearing until May,” Goldberg said. “But my yard's completely cleared of snowpack, and it has been for a couple weeks now.”

‘A haystack fire’

Battalion chief David Acuña, a spokesperson for Cal Fire, said fire season is shaped by more than just one year’s snowpack.

Climate change has been remaking California’s fire seasons into fire years. And California’s recent average to abundant water years have fueled what Acuña called “bumper crops of vegetation and brush.”

“Most of California is like a haystack. And if you’ve ever seen a haystack fire, they burn very intensely because there's layers of fuel,” Acuña said.

Like Quinn-Davidson, Acuña wasn’t ready to make specific predictions about fires to come.

But John Abatzoglou, a professor of climatology at UC Merced, said the temperatures and snowpack conditions this year offer a glimpse of California in the latter decades of this century, as fossil fuel use continues to drive global temperatures higher.

How this year’s fires will play out will depend on when, where and how wind, heat, fuel and ignitions combine. But it foreshadows the consequences of a warmer California for water and fire under climate change.

“This,” Abatzoglou said, “is yet another stress test for the future in the state.”
