An attempt by the Trump Organization to limit its liabilities at a polluted site in South Carolina once owned by President Trump’s oldest son may have just hit a wall.

The issue involves a company called Titan Atlas Manufacturing that Donald Trump Jr. helped to start in 2010 in North Charleston and that failed two years later.

In 2014, Donald J. Trump, while he was still running the Trump Organization, bailed out his son from the business misadventure by creating an entity called D B Pace. The new company took over a $3.65 million bank loan that had used the six-acre Titan Atlas site as collateral, and it eventually took ownership of the property itself.

Last year, D B Pace also applied to take part in a program offered by the State of South Carolina that would limit its liabilities for pollution on the property, like chemical contamination of groundwater.
