1.1.1 Incident Category
Time Critical, PRP
Led removal with EPA oversight.
1.1.2 Site Description
AEC
operated at the Site from 1981 to 1984 as a staging and re-packing facility for
the disposal of PCB transformers. The company also provided for the
transportation and disposal of others wastes. In 1984, a fire at the facility
contributed to the spreading of contamination throughout the Site. Portions of
the Site are open to the public and have residential dwellings located on the
property. Although previous removal actions were conducted, as noted above,
hazardous substances still remain on site.
1.1.2.1 Location
The Ellis
Road/American Electric Corporation Superfund Site is located in Jacksonville,
Duval County, Florida, and encompasses the former property on which American
Electric Corporation (AEC) operated, located at 475, 495 and 523 South Ellis
Road in Jacksonville, Duval County, Florida.
The Site is bounded
to the north by Arnold Avenue, the east by Roberts Street, the south by Harold
Avenue, and the west by South Ellis Road
1.1.2.2 Description of Threat
The American
Electric Corporation operated at the Site from 1981 to 1984 as a staging and
re-packing facility for the disposal of polychlorinated biphenol (PCB)
transformers. The company also provided for the transportation and disposal of
others wastes. In 1984, a fire at the facility contributed to the spreading of
contamination throughout the Site. Portions of the Site are open to the public
and have residential dwellings located on the property.
The results of the 2010 RSE published
in the Removal Investigation Report (RI) indicate the presence of PCBs at the
Site. PCBs are hazardous substances as defined by §101 (14) of CERCLA. The EPA
and the International Agency for Research on Cancer (IARC) have determined that
PCBs are probable carcinogens to humans. PCBs, if released from the Site, have
the capability of presenting a potential hazard to the occupants of the
property and potentially to neighboring properties. The threat comes primarily
from human exposure to the PCB contamination in surface soil through
residential traffic and land use over the contaminated areas of the property.
Direct contact, ingestion, and inhalation of PCBs are the primary pathways of
exposure. Continued exposure of PCBs in surface soils may cause chronic health
effects to the occupants of the property.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
Site sampling was
conducted from 12/02/2013 -12/11/2013.
Incremental sampling methodology was used to gather samples for
analysis. In order to further delineate the extent of contamination, a second round of sampling was performed in August, 2014. A synopsis of the results are below.
12 Sampling Units (Decision
Units) representing the 4 city blocks (Site)
PCBs 2 exceeded the Florida Residential SCTL of 500 ug/Kg
(both the former AEC facility parcels)
Dioxin 0 (zero) exceeded the Florida Residential SCTL of 7
ng/Kg (for 2,3,7,8 TCDD): Dioxins no exceedences.
Arsenic 3 marginally exceeded the Florida Residential SCTL of
2.1 mg/Kg; however, concentrations are representative of background
conditions.
Discrete Soil Sampling
PCBs completed in Dec 2013 and August 2014
69 soil sampling locations
150 individual soil samples
analyzed (plus QA/QC analysis)
Of the 150 soil samples, 31
exceeded the Florida Residential SCTL of 500 ug/Kg
6 concrete sample locations
collected for disposal purposes
6 individual concrete samples
(plus QA/QC)
1 exceeded 500 ug/Kg
None of the samples exceeded
the TSCA criteria of 50 ppm.
