Time-Critical - Removal Action	Pollution Report (POLREP) #5
Start Date: 8/16/2004

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.

Current Activities
Since POLREP No. 4, 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 is underway and is planned this fall or next spring, depending on weather conditions and plant availability, for the phase 2 properties.

$ Approximately 4000 tons of PCB contaminated soil <50 ppm PCB’s from digging phase 2 properties has been shipped off-site; about 2000 tons remains on-site to be shipped.

$ A Preliminary Assessment (PA) was performed on an additional 50 properties and access letters have been sent to 30 of them to perform a Site Investigation in the fall of 2005.

$ An Action Memo has been submitted to EPA Headquarters, requesting to exceed 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
• Finish hydro-seeding and vegetation restoration of phase 1 & 2 properties.

• Finish T&D of all excavated soil.

• Perform the Phase 3 SI in the fall of 2005 and subsequent indicated removal in the spring/summer of 2006.

Key Issues
• Use of a modern, auto-injector capable field GC was key to obtaining quick, accurate sample results and supported the digging rate. Use of SCRIBE instrumental in handling large amount of project data.

• Use of SCRIBE and ARCGIS will be required to be more automated on phase 3 to allow more efficient data management.
