Baldwinville Residential Properties

All POLREP's for this site Baldwinville Residential Properties
Baldwinville, MA - EPA Region I
POLREP #6 - POLREP #6, Update 		Printer Friendly  |   PDF
 
On-Scene Coordinator - Michael Barry 1/6/2006
Time-Critical - Removal Action Pollution Report (POLREP) #6
Start Date: 8/16/2004
Pollution Report (POLREP) #6
Site Description
The Site, located at Holman Street, near the village of Baldwinville in the town of Templeton, Worcester County, north 42 36' 54” latitude, west 72 04' 33” longitude, encompasses a neighborhood of approximately 55 residential properties. The site area is about 1/2 mile north of the village center and consists of about 80 acres total along Winchester, Holman, Harris, Elm and Bridge Streets and Winchendon Road.

This was discovered when soil sampling for polychlorinated biphenyls (PCB’s) at the adjacent Temple-Stuart removal site advanced to its property line without PCB concentrations declining below acceptable Massachusetts Department of Environmental Protection (MADEP) regulatory concentrations for residential areas. Subsequent sampling of the residential properties in 2003 confirmed PCB concentrations above MADEP levels at 28 properties; access to one phase 1 property was later denied by the owner. A phase 2 sampling in 2004 indicated PCB concentrations above MADEP levels at 22 of 26 properties investigated.  

For additional background information, please see the Action Memorandum


Current Activities
Since POLREP No. 5, the following work has been completed:

$ Digging of the 27 Phase 1 and 22 Phase 2 properties completed on August 17, 2005.

$ Loam backfill has been completed on all phase 1 & 2 properties and all but two have been hydro-seeded; the last two have been hand-seeded.

$ Restoration of trees and shrubbery of the Phase 1 properties was completed in September 2005. Phase 2 property tree restoration will be in the spring of 2006.  

$ All remaining PCB contaminated soil <50 ppm PCB’s from digging phase 2 properties has been shipped off-site; this was approximately 6000 tons.  

$ A Site Investigation was performed on 36 Phase 3 properties in October-November 2005. The PCB contamination has been bounded by the phase 3 SI; a small removal on 5-10 properties is planned for 2006.

$ An Action Memo Amendment was approved by EPA Headquarters on September 14, 2005. It approved exceeding the 12 months limit for a removal action and to raise the project cost ceiling to allow restoration of phase 1 & 2 properties to be completed and perform removal at required phase 3 properties in the spring and summer of 2006.


Planned Removal Actions
• Remove interference such as trees, outbuildings, yard ornaments, etc.

• Excavate surface soil as necessary to remove all grids containing PCB’s greater than 10 ppm and as necessary to achieve a yard-wide average of less than 2.0 ppm.

• Stage, transport and dispose of contaminated soil at a permitted facility.

• Backfill with clean sand to within 6” of surface, then with good quality, clean loam to grade and then hydro-seed the yards.

• Restore yard vegetation; shrubbery, trees.

• Continue use automated data systems as far as possible to support the project; including SCRIBE, Arcview GIS; etc.


Next Steps
Perform phase 3 removal action in spring/summer of 2006.

Replant trees and shrubs on phase 2 and 3 properties in summer 2006.

Complete project reports.

Key Issues
Use of electronic data deliverables provided for improved efficiency on the phase 3 SI data manipulation.
