2.1.1 Narrative
EPA
began a Time-Critical action consisting of the removal of PCB-contaminated soil
from a residential yard, residential right-of-ways and one commercial property
on May 27, 2014. Assistance from ERB was requested by the Remedial Branch after
the Remedial Investigation confirmed levels of PCBs in residential areas above
Removal Management Levels. The Time-Critical removal will consist of removing
and disposing of unsecured PCB-contaminated soils at or near the ground’s
surface throughout the site.
2.1.2 Response Actions to Date
On May 27, 2014, EPA initiated a removal action to mitigate
the threats posed by PCBs above the
Removal Management Level (RML) of 22 mg/kg for Total PCBs and Aroclor 1248; and
the RML of 3.4 mg/kg for Aroclor 1254 in
residential and commercial yards by removing and replacing clean soil.
Prior to May 27, 2014, access was obtained and START completed pre-excavation
assessments at all 10 impacted properties.
Between May 27, 2014 and June 06, 2014, EPA
removed approximately 488 tons of contaminated soil from the site for offsite
disposal. Waste was shipped to Wayne Disposal at 49350 North I-94 Service
Drive, Belleville, Michigan 48111.
Excavation was completed at one area of the commercial
property down 18 inches and the entire backyard at one residential property
down 24 inches. Confirmation samples
were collected for both properties. Analytical
results indicate that the commercial property required further excavation and another
6 inches is being removed. Results for
the residential property are due next week.
Air monitoring using a DataRam 4000 was conducted
during all work activities. Time-weighted
Average values ranged between 2.4 and 19.5 micrograms per meter cubed which is
below the site specific action level of 3,000 micrograms per meter. Two (one upwind and one downwind) air samples
were collected on May 30, 2014 and analyzed for PCBs. Both samples were non-detect.
