The Brief

California’s last nuclear power plant overcame a regulatory hurdle on Thursday when the California Coastal Commission voted to approve keeping the plant open for at least five years.

It was one of the final obstacles the controversial Diablo Canyon Power Plant had to clear to continue operating amid renewed opposition. The decision was conditioned on a plan that would require Pacific Gas & Electric, which owns the plant, to conserve about 4,000 acres of land on its property. That would prevent it from ever being developed for commercial or residential use.

The plant, located along the San Luis Obispo shoreline, now awaits federal approval for a 20-year relicensing permit.

“I don’t think, unfortunately, that anything will be happening to Diablo Canyon soon,” due to the growing energy demands of artificial intelligence, Commissioner Jaime Lee said before voting to approve the permit. Nine of the 12 voting members approved the plan.

The deliberations reignited decades-old concerns about the dangers of nuclear power and its place in the state’s portfolio of renewable energy sources. Diablo Canyon is the state’s single-largest energy source, providing nearly 10% of all California electricity.

Defeated in their earlier attempts to shut the plant, critics of Diablo Canyon used months of Coastal Commission hearings as one of their last opportunities to vocalize their disdain for the facility. Some Democratic lawmakers supported the plant but pushed for PG&E to find more ways to protect the environment.

Sen. John Laird, Democrat of San Luis Obispo County and former secretary of the California Natural Resources Agency, said on Thursday he approved of the new plan but pushed the commission to require the utility to conserve even more of its total 12,000 surrounding acres.

“If what comes out of this is the path for preservation for 8,000 acres of land, that is a remarkable victory,” Laird said.

Democratic Assemblymember Dawn Addis, whose district encompasses the plant, had also urged the commission in a letter to approve a permit “once it contains strong mitigation measures that reflect the values and needs of the surrounding tribal and local communities who depend on our coastal regions for environmental health, biodiversity and economic vitality.”

A long history of controversy

Founded in 1985, the plant’s striking concrete domes sit along the Pacific coast 200 miles north of Los Angeles. The facility draws in 2 million gallons of water from the ocean every day to cool its systems

And it has remained shrouded in controversy since its construction 40 years ago. Environmentalists point to the damage it causes to marine life, killing what the Coastal Commission estimates are 2 billion larval fish a year.

The commissioners on Thursday were not deciding whether to allow the plant to stay open but were weighing how best to lessen the environmental impacts of its operation. A 2022 state law forced the plant to stay open for five more years past its planned 2025 closure date, which could have led to significant political blowback against the Coastal Commission if it had rejected the permit.

Gov. Gavin Newsom reversed a 2016 agreement made between environmental groups and worker unions to close the plant after the state faced a series of climate disasters that spurred energy blackouts. Popular sentiment toward nuclear energy has also continued to grow more supportive as states across the country consider revitalizing dormant and aging nuclear plants to fulfill ever-increasing energy demand needs.

The 2022 law authorized a $1.4 billion loan to be paid back with federal loans or profits.

Groups such as the Environmental Defense Center and Mothers for Peace opposed the permit outright, citing concerns about radioactive waste, which can persist for centuries, and its cost to taxpayers.

“We maintain that any extension of Diablo is unnecessary,” and that its continued operations could slow the development of solar and wind energy, Jeremy Frankel, an attorney with the Environmental Defense Center told the commission Thursday.

The California Public Utilities Commission last year approved $723 million in ratepayer funds toward Diablo Canyon’s operating costs this year. It was the first time rate hikes were spread to ratepayers of other utilities such as Southern California Edison and San Diego Gas & Electric and was authorized by lawmakers because the plant provides energy to the entire state.

How the plant will be funded has also garnered scrutiny in the years since Newsom worked to keep it open. Last year, the Legislature nearly canceled a $400 million loan to help finance it.

As much as $588 million is unlikely to come back due to insufficient federal funding and projected profits, CalMatters has reported.

Proponents of the plant pointed to its reliability, carbon-free pollution and the thousands of jobs it has created.

Business advocacy groups emphasized their support for the plant as boosting the economy.

“It is an economic lifeline that helps keep our communities strong and competitive,” Dora Westerlund, president of the Fresno Area Hispanic Foundation, said at a November meeting.

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.”
