The State is also proposing a remedial plan to dispose of contaminated soils at an off-site disposal facility. Copies of the RIFS and the proposed remedial plan are available at the following website http://csmis12.mines.edu/ehs/csmri/csmri2007.htm. The RIFS and proposed plan may also be reviewed at the Site information repository located at the Colorado School of Mines Arthur Lakes Library Circulation Desk, 1410 Illinois Street, Golden, Colorado (303-273-3022). The RIFS evaluates the nature and extent of impacted soils at the CSMRI Site lower terrace as a result of prior mining research activities. Approximately 1,400 cubic yards of soil are impacted. The RIFS concludes that taking no further action is not appropriate to protect health and the environment. The RIFS reviews other alternative remedial actions and concludes that off-site disposal of all of the impacted soils is the preferred remedy. Other alternative remedies considered in the RIFS include capping the site, on-site consolidation and solidification, and partial off-site disposal and on-site consolidation and capping. The proposed plan selects off-site disposal of all the affected soil because it best meets the criteria for remedial actions. Ground water will be considered separately in a future RIFS. Public comments on the RIFS and the proposed plan are due on December 9, 2011. Written comments should be submitted to Mr. Linn Havelick, Colorado School of Mines, 1500 Illinois Street, Golden, CO 80401 (Linn.Havelick@is.mines.edu). A public meeting will be held at 7:00 p.m. Wednesday, November 30, 2011 at the Colorado School of Mines, General Research Building, Room 201, 1310 Maple Street, Golden, CO. The meeting will provide an opportunity to provide oral comments. An open house will be held from 5:00 PM to 7:00 PM immediately preceding the public meeting. All interested persons are welcome to attend. 11-30-2011 MEETING TRANSCRIPT For further information, contact Mr. Linn Havelick, Director, Environmental Projects, Environmental Health and Safety, Colorado School of Mines (303-273-3316).
