As we move into the final quarter of the year, I reflect on the significant progress made at the Energy Technology Engineering Center (ETEC), including completing sampling for our laboratory MRL studies. DOE remains steadfast in our commitment to safety and transparency as we tackle the remaining site remediation. This newsletter highlights recent developments at the Santa Susana Field Laboratory (SSFL).
Work plans for the Building 4024 basement demolition were submitted to the California Department of Toxic Substances Control (DTSC) for review and approval. The basement is the last remnant of the rich legacy of research and development of SNAP reactors. This plan sets the stage for our next milestone as we work with state regulators to gain their approval and continue progress at SSFL.
A recent achievement is the approval of a permit for a groundwater treatment pilot study using in-situ, or in-place, remediation techniques. We anticipate this innovative approach will accelerate our groundwater remediation efforts as we work towards the approval of our groundwater Corrective Measures Study. This pilot underscores our dedication to implementing efficient and effective remediation technologies.
Community engagement continues to be a vital aspect of DOE’s mission at SSFL. We will once again have a booth at the Simi Valley Street Fair in October, and I would like to invite our readers to visit us for a fun hands-on activity to create their own spectroscope.
We are committed to keeping you informed of our progress and engaging with the community through various initiatives.
Thank you for your continued interest in the ETEC site.
Sincerely,
Dr. Josh Mengers
