Document, Report, or Work plan Review - other |
As a landowner driven investigation and cleanup, in September 2021, RSE worked with Marble Construction to excavate approximately 2,015 tons of hydrocarbon impacted soil from the area surrounding boreholes BH-10, BH-10S, and BH-10S2 at the subject property. Soil was transported to Bicknell in Juneau for thermal treatment and to Republic Services landfill for disposal. The excavation did not reach the extent of the contaminated soil in all directions, but due to project constraints, the excavation was completed and backfilled. A report detailing this effort should be issued in the near future. An additional work plan which describes the methods for installing approximately 30 soil borings with as many as 10 completed as temporary monitoring wells to further delineate contamination in the proposed hospital building footprint area. RSE will collect soil and groundwater samples from these soil borings and monitoring wells. The data collected will be used to further delineate areas of hydrocarbon impacted soil at the site to support planning efforts for the new hospital construction project. DEC has reviewed both work plans but formal approval DEC approval is not required because the investigation is landowner driven.

Institutional Control Update |
In preparation for the constructions of a new SEARHC hospital and parking lots, a total of 6,669.53 tons of hydrocarbon impacted soil was transported under ADEC approval to Bicknell, Inc in Juneau, Alaska for thermal treatment in November 2022. A large portion of the project site was excavated down to bedrock to meet the MEMCC project structural requirements. Contaminated soil was left in place at the site in the southern and southeastern portion of the project limits at depths of approximately 5 to 20 feet below ground surface. This contaminated soil was later covered with 5 to 10 feet of clean overburden soil. All impacted material at the site was either removed down to bedrock or will be left in place under parking lots. No impacted material underlies the current new hospital building location or within a minimum of approximately 30 feet horizontally of the new hospital location. A site diagram of the excavations, remaining contaminated soil, and future building footprint is attached to this database record. |
