60-day public comment period: Sandia National Labs Mixed Waste Landfill Second Five-Year Report

The MWL is a 2.6-acre SWMU located in the north-central portion of Technical Area-III approximately five miles southeast of the Albuquerque International Sunport. The MWL was used as a disposal area for low level radioactive waste, hazardous waste, and mixed waste generated at SNL/NM research facilities and offsite locations from March 1959 to December 1988.

The May 2005 Final Order established the requirement for a five-year report assessing the remedy performance for the MWL. In the May 2005 Final Order, the NMED selected a vegetative soil cover with a biointrusion barrier (i.e., evapotranspiration [ET] cover) as the remedy for the MWL that includes unsaturated zone and groundwater monitoring. On January 8, 2014 NMED approved the MWL Long-Term Monitoring and Maintenance Plan (LTMMP), which started the first five-year evaluation period.

NMED received the MWL Second Five-Year Report in December 2023. The May 2005 Final Order requires that NMED provide a process whereby members of the public may comment on the MWL Second Five-Year Report and its conclusions and respond to those comments in its final approval of the MWL Second Five-Year Report.
