What Happens to a Landfill in a Hurricane?

The trash mostly stays put, but the methane is another story.

In the coming days and weeks, as Floridians and others in storm-ravaged communities clean up from Hurricane Milton, trucks will carry all manner of storm-related detritus — chunks of buildings, fences, furniture, even cars — to the same place all their other waste goes: the local landfill. But what about the landfill itself? Does this gigantic trash pile take to the air and scatter Dorito bags and car parts alike around the surrounding region?

No, thankfully. As Richard Meyers, the director of land management services at the Solid Waste Authority of Palm Beach County, assured me, all landfill waste is covered with soil on “at least a weekly basis,” and certainly right before a hurricane, preventing the waste from being kicked up. “Aerodynamically, [the storm is] rolling over that covered waste. It’s not able to blow six inches of cover soil from the top of the waste.”

But just because a landfill won’t turn into a mass of airborne dirt and half-decomposed projectiles doesn’t mean there’s nothing to worry about. Because landfills — especially large ones — often contain more advanced infrastructure such as gas collection systems, which prevent methane from being vented into the atmosphere, and drainage systems, which collect contaminated liquid that’s pooled at the bottom of the waste pile and send it off for treatment. Meyers told me that getting these systems back online after a storm if they’ve been damaged is “the most critical part, from our standpoint.”

A flood-inundated gas collection system can mean more methane escaping into the air, and storm-damaged drainage pipes can lead to waste liquids leaking into the ground and potentially polluting water sources. The latter was a major concern in Puerto Rico after Hurricane Maria destroyed a landfill’s waste liquid collection system in the Municipality of Juncos in 2017.

As for methane, calculating exactly how much could be released as a result of a dysfunctional landfill gas collection system requires accounting for myriad factors such as the composition of the waste and the climate that it’s in, but the back of the envelope calculations don’t look promising. The Southeast County Landfill near Tampa, for instance, emitted about 100,000 metric tons of CO2 equivalent in 2022, according to the Environmental Protection Agency (although a Harvard engineering study from earlier this year suggests that this may be a significant underestimate). The EPA estimates that gas collection systems are about 75% effective, which means that the landfill generates a total of about 400,000 metric tons of CO2-worth of methane. If Southeast County Landfill’s gas collection system were to go down completely for even a day, that would mean extra methane emissions of roughly 822 metric tons of CO2 equivalent. That difference amounts to the daily emissions of more than 65,000 cars.

That’s a lot of math. But the takeaway is: Big landfills in the pathway of a destructive storm could end up spewing a lot of methane into the atmosphere. And keep in mind that these numbers are just for one hypothetical landfill with a gas collection system that goes down for one day. The emissions numbers, you can imagine, start to look much worse if you consider the possibility that floodwaters could impede access to infrastructure for even longer.

So stay strong out there, landfills of Florida. You may not be the star of this show, but you’ve got our attention.

Trump Promises ‘Fully Expedited’ Permitting in Exchange for $1 Billion of Investment

But ... how?

President-elect Donald Trump on Tuesday rocked the energy world when he promised “fully expedited approvals and permits, including, but in no way limited to, all Environmental approvals” for “Any person or company investing ONE BILLION DOLLARS, OR MORE, in the United States of America,” in a post on Truth Social Tuesday.

“GET READY TO ROCK!!!” he added.

The Mad Dash to Lock Down Biden’s Final Climate Dollars

Companies are racing to finish the paperwork on their Department of Energy loans.

Of the over $13 billion in loans and loan guarantees that the Energy Department’s Loan Programs Office has made under Biden, nearly a third of that funding has been doled out in the month since the presidential election. And of the $41 billion in conditional commitments — agreements to provide a loan once the borrower satisfies certain preconditions — that proportion rises to nearly half. That includes some of the largest funding announcements in the office’s history: more than $7.5 billion to StarPlus Energy for battery manufacturing, $4.9 billion to Grain Belt Express for a transmission project, and nearly $6.6 billion to the electric vehicle company Rivian to support its new manufacturing facility in Georgia.

The acceleration represents a clear push by the outgoing Biden administration to get money out the door before President-elect Donald Trump, who has threatened to hollow out much of the Department of Energy, takes office. Still, there’s a good chance these recent conditional commitments won’t become final before the new administration takes office, as that process involves checking a series of nontrivial boxes that include performing due diligence, addressing or mitigating various project risks, and negotiating financing terms. And if the deals aren’t finalized before Trump takes office, they’re at risk of being paused or cancelled altogether, something the DOE considers unwise, to put it lightly.

Treasury Finalizes Another IRA Tax Credit Before You Know What

The expanded investment tax credit rules are out.

In the waning days of the Biden administration, the Treasury Department is dotting the i’s and crossing the t’s on the tax rules that form the heart of the Inflation Reduction Act and its climate strategy. Today, Treasury has released final rules for the Section 48 Investment Tax Credit, which gives project owners (and/or their tax equity partners) 30% back on their investments in clean energy production.

The IRA-amended investment tax credit, plus its sibling production tax credit, are updates and expansion on tax policies that have been in place for decades supporting largely the solar and wind industries. To be clear, today’s announcement does not contain the final rules for the so-called “technology-neutral” clean electricity tax credits established under the IRA, which will supercede the existing investment and production tax credits beginning next year and for which all non-carbon emitting sources of energy can qualify.
