In mid-December 2004, Semnani sold Envirocare for an undisclosed sum. Steve Creamer became the company's new CEO. The deal was financed by private equity firms, led by Lindsay Goldberg & Bessemer of New York, Creamer Investments, and Peterson Partners both of Salt Lake City. Envirocare management promised to drop plans to bury hotter class B and C nuclear waste in Utah in deference to developing political opposition to the company, which was poised to ban the waste anyway. Envirocare's management and ownership was retained as it made the acquisitions to become EnergySolutions.
