SUBJECT:
REVIEW OF AMBROSIA LAKE GROUND WATER COMPLIANCE ACTION PLAN i
Dear Mr. Metzler:
The U.S. Nuclear Regulatory Commission (NRC) staff has completed its review of the Ambrosia Lake, New Mexico, Ground Water Compliance Action Plan (GCAP), dated April 1998, which was submitted by a U.S. Department of Energy (DOE) letter dated June 1,1998. The GCAP reiterates DOE's strategy of "No-Ground-Water-Remediation," based on the ground water in the uppermost aquifer being classified as limited use and, thus, no program to monitor ground water is required.
As discussed in the enclosed Supplemental Technical Evaluation Report (STER), the NRC staff has reviewed the GCAP, and agrees with DOE that the uppermost aquifer does not represent a i
ground-water resource, because of the limited extent of saturation in the aquifer and its inability to sustain a yield of 150 gallons (570 liters) per day to wells. The uppermost aquifer is expected to return to its premilling and mining condition of little-to-no saturation, furthe:
eliminating the unit as a potential future ground-water resource. Ground water does not discharge to the land surface, and the nearest surface water is located approximately 1.S miles j
(2.4 kilometers) southwest of the site. No current exposure pathways due to ground-water contamination exist, nor are any foreseen.
Based on the above, the NRC staff concurs with the GCAP. If you have any questions concerning this letter or the enclosed STER, please contact the NRC Project Manager, Ken Hooks, at (301) 415-7777.

REVIEW OF AMBROSIA LAKE GROUND WATER COMPLlANCE ACTION PLAN
Dear Mr. Metzler:
The U.S. Nuf 1r Regulatory Commission (NRC) staff has completed its review of the Ambrosia Lake, New Mexico, Ground Water Compliance Action Plan (GCAP), dated April 1996, which was submitted by a U.S. Department of Energy (DOE) letter dated June 1,1998. The GCAP reiterates DOE's strategy of"No-Ground-Water-Remediation," based on the ground water in the uppermost aquifer being classified as limited use and, thus, no program to monitor ground wateris required.
I As discussed in the enclosed Supplemental Technical Evaluation Report (STER), the NRC staff has reviewed the GCAP, and agrees with DCE that the uopermost aquifer does not represent a ground-water resource, because of the limited extent of saturation in the aquifer and its inability to sustain a yield of 150 gallons (570 liters) per day to wells. The uppermost aquifer is expected to return to its premilling and mining condition of little-to-no saturation, further eliminating the unit as a potential future ground-water resource. Ground water does not discharge to tha land surface, and the nearest surface water is located approximately 1.5 mees (2.4 kilometers) southwest of the site. No current exposure pathways due to ground-water contamination exist, nor are any foreseen.
Based on the above, the NRC staff concurs with the GCAP. If you have any questions conceming this letter or the enclosed STER, please contact the NRC Project Manager, Ken Hooks, at (301) 415-7777.
