Conditional Closure Approved |
ADEC has determined that no further remedial action is required at this site even though levels of hazardous substances remain in soil and groundwater above the established cleanup levels. Contaminated soil that exceeds the ingestion and inhalation pathways is capped with an asphalt cover to prevent exposure. The contamination that remains on the property will naturally attenuate and/or remedial measures may be employed to enhance the natural processes. The groundwater on the eastern portion of the site will be treated using an air sparge system. If (or when) soil contamination is excavated, it shall be subject to the cleanup rules that require treatment and disposal in accordance with 18 AAC 75 regulations. |
Todd Blessing |
| 6/22/2005 |
Institutional Control Record Established |
Institutional controls established are as follows:
1. any proposal to excavate and/or transport soil from the area requires ADEC approval in accordance with 18 AAC 75.325(i);
2. groundwater shall be monitored in accordance with 18 AAC 75.345(h) to ensure contamination is decreasing and/or not migrating off site. A groundwater monitor plan shall be submitted for ADEC review and approval;
3. this site shall be listed in the Department’s database as a conditional closure with applicable restrictions and/or conditions; and
4. if future information indicates contamination is present at levels that may pose a risk, additional assessment and/or cleanup action may be required;
5. a Notice of Environmental Contamination documenting the nature and extent of contamination remaining on site shall be attached to the property. It must be a recorded document (in the State Recorder’s Office) that identifies contamination issues and any restrictions and/or conditions necessary to protect human health and the environment. |

Correction to the 2017 IC reminder letter which listed as an institutional control the recommendation of running the air sparging system. This is incorrect since it is only a recommendation, not an institutional control/land use restriction. |
Evonne Reese |
| 8/21/2019 |
Update or Other Action |
Construction and redevelopment is currently taking place on this property according to the soil management plan approved in May 2019. A small volume of suspected contaminated soil was encountered and placed into three different stockpiles. The stockpiles were sampled with a modification in the number of samples from the soil management plan, with approval from CS program management. The analytical results showed all samples were below cleanup levels, therefore I provided approval to use the soil as part of the redevelopment on the property. I also provided an approved soil transport form in case any clean soil is moved from the site.
