Site Facts



Many NPL sites are large and complicated. These sites are often broken up into smaller areas to make cleanup easier and more manageable. These areas are called “Operable Units” or OUs. Activities and funding that are applicable to the entire site are tracked under OU 00, often called the “Sitewide” operable unit. All sites have this operable unit. This page provides a list of all of the Operable Units at this site.

Contaminants listed below, if any, reflect those present at the site at the time the Record of Decision (ROD) is completed. No contaminants listed indicates that the ROD has not yet been completed.

Cleanup technology selected listed, if any, reflects the selected technology decision in the ROD. No cleanup technology listed indicates that the ROD has not yet been completed.
