United Site Services, which owns 350,000 portable restrooms, filed for bankruptcy in New Jersey on Monday with a plan to eliminate $2.4 billion in debt and hand control to the company’s lenders.

USS, which is owned by private equity firm Platinum Equity Partners, said that a majority of the company’s lenders have agreed to support the restructuring plan. Despite the high level of support, one large holdout creditor opposes the plan and could pursue a path of “delay and litigation,” according to USS’ court filings.
