Clean up of salt pile that devastated Mentor Marsh will cost another $3M

- By Peter Krouse

It’s going to cost another $2.97 million to clean up the infamous “salt fill site” that contaminat­ed Mentor Marsh decades ago and created a major environmen­tal disaster that is still being dealt with today.

The additional funds will increase the amount allocated for the remediatio­n project to more than $13.5 million.

The extra money was requested after excavation began earlier this year and 50,000 tons of additional salt was unexpected­ly discovered at greater depths, according to a news release from the office of Ohio State Rep. Daniel Troy, Democrat of Willowick.

The project has also experience­d increased costs for fuel, heavy equipment and wastewater disposal.

Most of the money — $10.6 million — is being paid by the estate of Jerome T. Osborne as part of a consent order reached in 2019 that is designed to remove the salt and other contaminan­ts that were first deposited along Blackbrook Creek, a feeder stream that flows into the marsh, more than 55 years ago.

After various attempts to prevent the salt from leaching into the marsh, the Ohio Attorney General sued Osborne on behalf of the Ohio EPA in 2013.

Osborne had been hired by the Morton Salt Co. in the 1960s to get rid of lowgrade salt that had no commercial value, and Osborne decided to spread it on land he owned along Blackbrook Creek.

What resulted was massive destructio­n of native trees in what had once been a forested wetland. Invasive species moved in, including phragmites, that drove out native plants and animals. The marsh has recovered to some extent in recent years thanks to the efforts of the Cleveland Museum of Natural History, the Ohio Department of Natural Resources and others.

The $2.97 million will be taken from prior settlement­s the Ohio EPA has reached to pay for remediatio­n projects. Troy said it will be up to the Ohio EPA to decide whether to seek reimbursem­ent of that money from the Osborne estate.

“I’m sure they’ll try,” he said.

Osborne, who died in 2014, was a prominent businessma­n in the area.
