1.1.1 Incident Category - Time-Critical Removal Action
1.1.2 Site Description
Centredale Manor and Brook Village are two elderly housing hi-rise complexes that are located on the site of a former chemical manufacturing facility. Manufactuing ceased in the 1970's when the chemical plant building was destroyed by fire. The primary contaminant at this site is 2,3,7,8-tetrachlorodibenzodioxin (TCDD or dioxin). Dioxin has also been identified in samples collected from surface soils in wetlands and flood plain areas downstream of the Site. These areas will be addressed in the long term remedy for the Site. The past use of the Site as a chemical manufacturing company and a barrel reclamation facility is not inconsistent with the presence of dioxin. EPA has established that hexachlorophene was manufactured at the Site; dioxin is a well-documented byproduct of hexachlorophene production.
The Centredale Manor Restoration Project Site as described in the National Priorities List encompasses the following:
the soil, surface water, sediment and flood plain of the Woonasquatucket River from the bridge at Route 44 in North Providence, downstream to the Lyman Mill Dam, including all contaminated areas within this area and any other locations where contamination from this area has come to be located; and the Brook Village and Centredale Manor Apartment properties which are located at 2072 and 2074 Smith Street in North Providence, Providence County, Rhode Island.
Brook Village and Centredale Manor are zoned for residential occupancy and encompass a total of 9.7 acres of land. Centredale Manor was constructed in 1983. It is an eight-story apartment building for elderly and handicapped. There are two paved parking lots located to the north and west of the building.
Brook Village was constructed in 1977. It is an eleven-story apartment building for elderly and handicapped residents. A series of parking lots extend to the south of the building. The area around both buildings is landscaped with grass ground cover.
Both properties are privately owned and are currently active apartment buildings, providing subsidized housing for several hundred elderly residents.
The approximate area population is :
1,091 people within ¼ mile
3,334 people within ½ mile
13,516 people within 1 mile
Also within 1 mile of the site are two other elderly care facilities, three public schools, three private day schools, and six daycare facilities.
According to the EPA Region 1 Environmental Justice Mapping Tool, the Site is not in an environmental justice area.
1.1.2.1 Location
The Brook Village Apartment property (Brook Village), is located at 2072 Smith Street, North Providence, Providence County, Rhode Island
The Centredale Manor Apartment property (Centredale Manor), is located at 2074 Smith Street, North Providence, Providence County, Rhode Island.
The geographic coordinates for the Site are 41° 51' 29.5" north latitude and 71° 30' 28.5" west longitude.
1.1.2.2 Description of Threat
The compound 2,3,7,8-tetrachlorodibenzo-p-dioxin (dioxin or TCDD) is a hazardous substance as defined in Section 101(14) of CERCLA and is listed at 40 CFR 302.4. Analytical data from the samples collected at this Site indicate dioxin concentrations up to 33ppb in surficial and sub-surface soils. The conceptual site model describes migration of dioxin facilitated by VOCs such as tetrachloroethylene and trichloroethylene, via groundwater to the surface water and sediments of the Woonasquatucket River. Human health and the environment are negativelynimpacted by exposure to the surface waters and sediments of the river.
This removal action will address a source of loading and/or leaching of contaminants from the source area into the waters and sediments of the Woonasquatucket River.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
On January 31 and February 05, 2008 groundwater monitoring wells were installed at the site as part of the Remedial Investigation/Feasibility Study (RI/FS) for the EPA Remedial Program. Samples of the soil borings were analyzed and revealed elevated levels of dioxin in surface and subsurface soils. EPA has determined that dioxin is migrating to the adjacent Woonasquatucket River. Though dioxin is not soluble in water, migration may be facilitated by elevated levels of volatile organic compounds found in the same samples.
EPA has evaluated this data and other data found in the Interim Final Remedial Investigation, June 2005. A Preliminary Assessment (PA) was initiated by OSC Bazenas on March 26, 2009 and updated on June 26, 2009. The Site Investigation Closure Memorandum dated July 13, 2009 documents the determination that a Removal Action is appropriate at this Site.

2.1 Operations Section
|
|
|
|
2.1.1 Narrative
This Removal Action is being undertaken by the Potentially Responsible Party (PRP of the respondent) under a Settlement Agreement and Administrative Order on Consent (AOC), effective August 11, 2009. The actions are further supported by an Action Memorandum signed on July 17, 2009, should the respondents fail to perform.
The specific actions to be performed under the AOC are designed to control the migration of dioxin to the surface waters of the Woonasquatucket River by excavating contaminated soil for off-site disposal, and installation of an impermeable cap over residual contamination.
On September 15, and September 22, 2009, the weekly site progress meeting was held at the site. Excavation of highly contaminated soil continued daily throughout this period.
By September 28, 2009, the respondents had shipped 84 loads of contaminated soils to the Bennet Incinerator Facility in Canada. Nearly all soil for disposal have been excavated and stockpiled at the site. Shipping will continue.
In addition, excavation and reuse of onsite soils for regrading will continue in preparation for cap construction.
2.1.2 Response Actions to Date
EPA and The Rhode Island Department of Environmental Management (RIDEM) have undertaken several previous actions at the Site including time-critical removals, non-time-critical removals and remedial actions to characterize the extent of contamination, remove contaminated soils from adjacent residential properties, construct earthen caps over contaminated areas, and reconstruct a dam on the Woonasquatucket River. Please refer to previous Action Memoranda and the Administrative Record for additional information.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
The actions to be performed under this Order are undertaken voluntarily by the respondent, Emhart Industries, Inc.
