R. A. Scarano 2-Discussion All attendees met at the New Mexico EID field office in Milan, for introductions and a brief overview of the proposed project, and then proceeded to the mill site.
The mill is proposed for a elevated area in the W 1/2, SW 1/4, Sec 12, T18N, R12W in McKinley County New Mexico, with the tailings impoundments to occupy 'much of the remaining area of the section. The applicant proposes to hydrocyclone the tailings, discharging sands into a 250 acre impoundment, and slurrying the slimes fraction into a separate 220 acre impoundment. Both impoundments will be partially below grade, with the bottom alluvium being excavated from 3 to 45 feet to the bedrock.
An S shaped dam will be constructed around the impoundments to a maximum height of approximately 100 feet.
Three alternatives sites were examined by the applicant, but these could not be visited because of the deep mud and poor road conditions caused by recent rains and mine related construction activities.
Potential problem areas on which additional infonnation will likely be sought include:
1.
The source and extent of a shallow body of ground water lying under the SE corner of the slimes impoundment; and.
2.
The adequacy of the reclamation plan for site staLility and radon attenuation.
The visit ended with a discussion among the NMEID, NRC and CSU representatives'on the above topics and individual impressions of the proposal.
