Document, Report, or Work plan Review - other |
ADEC approves the 'Final 2017 Five-Year Review, King Salmon Divert, Naknek Recreation Camp I, Naknek Recreation Camp II, Alaska, November 2017' in a letter dated May 15, 2018. Land Use Controls have not been fully implemented at any groundwater zones at King Salmon Divert. Recommendations include: finalizing the decision document for Zone 7, determine the extent of drinking water wells at Lake Camp (number of wells, depth of wells, and groundwater gradient), and fully implement LUCs by updating public land records for non-USAF owned properties. The next five-year review will be completed in 2022. |
