Environmental Programs

Groundwater and Soil

Soil and groundwater are being investigated and, where necessary, remediated at the Santa Susana Field Laboratory under the guidance of the Resource Conservation and Recovery Act (RCRA) Corrective Action Program as administered by the California Environmental Protection Agency (CalEPA) Department of Toxic Substances Control (DTSC). More information about DTSC oversight of cleanup can be found on the DTSC Web site.

Operable Units and Groups

Since the early 1980s, Santa Susana Field Laboratory site characterization has proceeded along two parallel paths, one for soil and related surficial media and the other for groundwater. In 1999, DTSC formalized this approach by identifying two Operable Units (OUs). The soil and groundwater OUs are named the Surficial Medial Operable Unit (SMOU) and the Chatsworth formation Operable Unit (CFOU), respectively. The SMOU is currently subdivided into 11 RCRA Facility Investigation (RFI) Groups (see map) whereas the CFOU is not subdivided.

RCRA Corrective Action Program and Schedule

The RCRA Corrective Action Program consists of four basic phases:

Because of the size and complexity of the Santa Susana Field Laboratory site, our Boeing Project Managers developed an in depth, multi-level schedule which we use to track our progress toward the 2017 goal. A summary schedule which has been submitted to DTSC shows the critical deadlines for the SSFL RCRA Corrective Action Program.
