Merrimack, New Hampshire Property. Nashua has performed groundwater and soil remediation work in the vicinity of the old underground storage tanks. Monitoring continues and operations continue under a groundwater management plan. In 2000, there was a spill on the site, which has been cleaned up, but may require further remediation and cleanup. Estimated cost to complete the remediation is in a range between $302,000 — $506,000. The State has approved the remediation plan submitted by Nashua which has been commenced by Nashua. Active toluene remediation is estimated to continue past 2007. In addition, the Company is working with the EPA to resolve the remediation issue relative to PCBs found on the site. Our environmental consultants believe that remediation of PCBs will be limited to capping the PCB site and the issuance of a deed restriction for the location.
Merrimack, New Hampshire Property. Nashua has performed groundwater and soil remediation work in the vicinity of the old underground storage tanks. Monitoring continues and operations continue under a groundwater management plan. In 2000, there was a toluene spill on the site. The State has approved the remediation plan submitted by Nashua and active toluene remediation continues. The DES approved the moving of the air sparging system in 2007 to aggressively accelerate the toluene cleanup. In addition, the Company is working with the EPA to resolve the remediation issue relative to PCBs found on the site. PCBs were used in the manufacture of carbonless products in the late sixties-early seventies. Our environmental consultants, Xxxxx & Xxxxxxx, believe that remediation of PCBs will be limited to capping the PCB site and the issuance of a deed restriction for the location. On September 27, 2007, representatives of the EPA and NH DEA visited the Merrimack site. The EPA is concerned that PCBs could be migrating off site into the Merrimack River. The EPA arrived at the possibility based on detection of PCBs in groundwater at the property boundary at the last two well sampling events. In order to address the issues raised by the EPA, Nashua with the assistance of Xxxxx & Xxxxxxx prepared a statement of work approved by the EPA which called for additional groundwater sampling for PCBs coupled with further evaluation of the hydrogeolic condition and other potential PCB sources and additional soil boring, testing and monitoring xxxxx. Testing of PCBs indicates potential migration of PCBs to xxxxx on the property boundary. The estimated cost for the PCB work ranges between $50,000 and $100,000 and has been included in the reserve range limits. Groundwater sampling was performed in May 2008. PCB concentrations in groundwater were relatively unchanged from previous sampling events. Toluene concentrations have been significantly reduced due to the operation of the air sparge system. Xxxxx and Xxxxxxx submitted the final supplemental PCB Data Evaluation Report to the EPA and the New Hampshire Department of Environmental Services on June 6, 2008. The recommendation continues to be to cap the contaminated area and place use restrictions on the PCB impacted soils. Groundwater sampling was performed in November 2008. The New Hampshire Department of Environmental Services issued a new Groundwater Management Permit on December 16, 2008. The permit requires testing of fewer xxxxx than what was previously teste...
