It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.
Problems/Comments
A 1992 site investigation report identified possible unacceptable lead levels in soil around some of the buildings. Dust sampling for lead was conducted in 1997 and it was recommended that inside of buildings be cleaned to prevent lead dust exposure to building restoration workers. In soil lead contamination is primarily between building outer walls to the building drip line with greater extents in some areas. Lead paint mitigation has occurred as buildings have been restored.

| 6/30/2008 | Exposure Tracking Model On Hold | The file indicates that a lead paint workplan was submitted in 1999. The workplan is not in the file. Inforamtion is available int he file about lead on buildings, but not about lead in soil aroudn the buildings. This site ranking has been place on hold until the workplan and subsequent site efforts can be requested from NPS. If lead contamination has not been found in the soil associated with paint chips from the building, the status of this site should be changed to unconfirmed. | Janice Wiegers |
| 7/1/2008 | Exposure Tracking Model Ranking | Initial ranking with ETM completed. | Janice Wiegers |
| 6/15/2009 | Update or Other Action | Initial ranking corrected due to ETM error in surface water pathway. | Mitzi Read |
| 9/30/2014 | Potentially Responsible Party/State Interest Letter | Potentially responsible party letter sent to the National Park Service. | Melody Debenham |

| 6/26/2017 | Meeting or Teleconference Held | NPS officials from the Contaminated Sites Program in Denver and from the regional office in Anchorage traveled to Nabesna and Kennicott mines to develop a strategy for investigation and remediation of the mines. DEC participated in a preliminary meeting to share information on the each agency's contaminated sites program and broad vision for the future of the sites. | Joy Whitsel |

Work was begun at the site before ADEC had the necessary time to review, comment, and correspond to approve the RI SAP. ADEC requires further characterization from what is detailed in the SAP, to be conducted at a later date. A detailed CSM needs to be completed to understand the data gaps to fill in future years. ADEC also requested several reports that had not been delivered to ADEC for review in years' past. | Tim Sharp |
| 8/17/2022 | Meeting or Teleconference Held | ADEC met with NPS and representatives from Ahtna to discuss multiple site histories and potential paths forward for remediation and eventual closure with or without ICs. | Tim Sharp |
