1.1.1 Incident Category

            Time-Critical Removal

1.1.2 Site Description

            Merrimack Industrial Metals is a 5 acre site, designated as Lot 6-1 on Merrimack Tax Assessors Map 2B, and is the location of a former metals recycling facility that operated between 1963 and 1999 when Merrimack Industrial Metals (MIM) ceased operations.  The site is located adjacent to Pennichuck Brook, a Class A Water Body and the main water supply source for the City of Nashua.  The site also abuts and is located within the wellhead protection area for the Merrimack Village District (MVD) Municipal Supply Well #6 (Well#6).  

            A stockpiled soil pile was created during a cleanup attempt that occurred from October to December 1999, as part of negotiations for the sale of the property.  The sale of the property never took place.  The soil pile is located approximately 250 feet from Pennichuck Brook and 1200 feet from Well #6. Description of Threat

            Surface soils and waste piles are contaminated with lead up to 2,800 mg/kg and polychlorinated biphenyls up to 72 mg/kg.  The applicable New Hampshire cleanup standards for surface soils in a commercial setting are 1000 mg/kg for lead and 25 mg/kg for polychlorinated biphenyls. 

            These contaminated surface soils are exposed and accessible to those who may enter the Site.  Sparse vegetation in these areas may make these soils prone to migration via erosion.

2. Current Activities
  2.1 Operations Section
    2.1.1 Narrative

            EPA is conducting a fund-lead removal action to address conditions at
the Site. 
Media attention is low, although local political attention is moderate due to the location of the well in proximity of the Site.
2.1.2 Response Actions to Date

            There has been no use of the OSC warrant authority.

            EPA conducted a site walk with the ERRS contractor on 20 April 2009.

            On the week of 04 May 2009, the ERRS contractor deployed resources to the Site including an operational Site trailer, storage container, adequate temporary bathroom facilities, and handwash station.  START personnel divided the Site into 30 foot grids and placed pin flags in order to define the extent of contamination.   

            On the week of 11 May 2009,  the ERRS contractor deployed temporary high visibility fence to restrict access to the Merrimack Industrial Metals Site.  Silt fence was also installed to restrict any soils from the Site from migrating.  A skid steer was outfitted with a sweeper to clear asphalted areas of small metal debris to ensure personnel and vehicle safety.  Clearing of brush has commenced, with root balls being left in place for disposal.  EPA's mobile lab was deployed to the Site in order to field screen samples as part of an extent of contamination survey.     
2.1.4 Progress Metrics

            Waste remains in stockpiled soils on-site.  Initial estimates of existing piles call for the disposal of 1,000 cubic yards of material.
