Problems/Comments
Landfill 2 (LF2) is a subarea of Site LF002 at the former Kalakaket Creek Radio Relay Station (RRS). LF2 is located north of the former RRS. The selected remedy for LF2, identified in the 2010 LF002 Decision Document includes institutional controls to protect against potential future exposure to unknown contamination emanating from the landfill. The major components of the selected remedy include: 1) visual monitoring of the top cover of each landfill for signs of settlement, subsidence, erosion, or other such events once every 5 years or until ADEC approves discontinuation of monitoring, 2) Maintaining the integrity of the cap to limit exposure to landfill contents, which includes making repairs and preventing run-on or run-off from eroding or otherwise damaging the cover, 3) restricting access to and limit exposure from contaminated soil at LF1, 4) inclusion and documentation of all ICs in USAF Real Property Records, 5) maintaining existing administrative controls, 6) Submittal of a performance report on ICs to ADEC every 5 years after implementation of the remedial action, and 6) ICs and requirements of 18 AAC 60 to remain as long as buried waste remains onsite.
