Mound History

Mound

---

The DOE Mound Plant was established in late 1946 as a facility to support atomic weapons research and energy programs. It is located on 306 acres in the southwest portion of the City of Miamisburg, Ohio.   The primary mission of the Mound Plant over the years was the development, engineering, manufacturing, and evaluation of explosive components for the nuclear weapons program.  Monsanto operated the plant from 1946 until 1988.  EG&G, Babcock & Wilcox, and CH2MHill have contracted with DOE to cleanup the Mound site since operations ceased.  

The Mound Plant was placed on the  National Priorities List (NPL) in 1989 due to past waste disposal practices and releases to the environment.  As a result, cleanup efforts were initiated under the Comprehensive Response, Compensation and Liabilities Act (CERCLA, also known as "Superfund").  DOE operations at the site are scheduled to be phased out over the next several years.  Today, Mound's primary mission is an environmental restoration program designed to make the site environmentally safe and appropriate for commercial and industrial use.
