Maui’s toxic debris could fill 5 football fields 5 stories deep. Where will it end up?

LAHAINA, Hawaii — Hinano Rodrigues remembers being 4 or 5 years old, carrying a bucket across a highway to the ocean in the Maui community where he still lives.

At dawn, he would accompany his grandmother to a reef at low tide, where she plucked black snails, spiny lobsters and spiky sea urchins from the craggy rock. In Hawaiian, she would instruct him to break off a branch of kiawe, a type of mesquite, to tease out an octopus hiding in a hole.

It taught Rodrigues, 71, the value of ahupuaa, a Native Hawaiian system for dividing land from the mountains down to the ocean, with the residents of each section living off the land and waters within it.

But now the section where he lives and where his ancestors have always lived — the Olowalu ahupuaa — is also home to a temporary landfill being used to store debris from the deadly wildfire that decimated the historic nearby town of Lahaina last summer, destroying thousands of buildings and killing 102 people. It’s enough refuse to cover five football fields five stories high, including soil contaminated with lead and arsenic.

A controversy over whether that site is truly temporary — and over where the debris might finally wind up — has sparked a fierce legal fight with tens of millions of dollars at stake, not to mention a priceless ecosystem rich with coral, manta rays and other sea life just offshore.

“Why would you go put opala like this in a place that’s clean?” Rodrigues asked, using a Hawaiian word for trash.

Handling debris after large wildfires is always a logistical challenge. After the 2018 Camp Fire killed 85 people and burned down most of the town of Paradise, California, more than 300,000 truck loads were required to transport the debris to three different landfills, said Cole Glenwright, the deputy incident commander of the debris removal operation. The whole process took about a year.

It’s taking much longer on Maui, given environmental concerns, how long it has taken to clear destroyed lots, worries about Native Hawaiian cultural sites, and tussling over the ownership of a potential permanent site for the debris.

The temporary landfill in Olowalu is a former quarry on state-owned land and close to Lahaina, which made it a convenient choice for quickly storing the debris being cleared away so the town can rebuild. Officials believe its arid climate will reduce the risk of contamination spreading, and they say they’ve taken many precautions, including using thick liner and stormwater…
