Re: Nominmion for National Priorities ListofSuperfund Sites UnimaticManufacturingCorporation (Unimatic) 2.5 Sherwood Lane Fairfield (Essex County) DEP/SRPPI#:99235
Dear Ms. Enck:
The New Jersey Department of Environmental Protection (DEP) nominates the Unimalic Manufacturing Corporation site in the Fairfield Township, Essex County for inclusion on the National Priorities List (NPL) of Superfund sites. The Unimatic site contains significantly elevated levels ofpolychlorinated biphenyl (PCB) contamination in soil and groundwater and a buildinginterior.
On March 8, 2013, the New Jersey Department ofHealth, working through the federal Agency for Toxic Substances and Disease Registry (ATSDR), provided a health consultation that recommends workers using the former Unimatic building should be re-located as soon as feasible in order to prevent on-goingexposure to PCBcontamination. This recommendation was made upon review ofdata collected recently by U.S. Environmental Protection Agency (EPA)'s Removal Action Branch at the subject facility. DEP referred the Unimatic site to EPA in May 2012 for further assessmentdue the elevated levels ofPCB contamination.

DEP requests EPA Region II's Emergency and Remedial Response Division expand upon past removal assessment studies at the site to delineate soil and groundwater contamination and implement appropriate measures to protect human health and ensure safe reuse of the property. In addition, DEP concurs with EPA's plans to assess and prevent PCB contamination from leaving the former Unimatic building as the currently operating company implements its relocation.

N!'l:·Jerse_r is 1111 Equal Oppommir:vEmployer 1Primed 011 RecycledPaperundRecyclableDEP referred the site to EPA due to the elevated PCB levels in soils near the surface around the former Unimatic building. Previous soil sample results by the responsible party range up to 990 parts per million (ppm) in the top few feet in areas near the building, 2,180 ppm at depth around building and 2,530 ppm under the structure now used as

EPA"s Region II Pesticides & Toxic Substances Branch has been working with DEP to identify specific concerns ofnot only soil and groundwater contamination at the Unimatic site, but also interior building contamination. To date, a responsible party for the site has not presented 

### a remedial action plan to address all contamination concerns by DEP and EPA Region 

### II's Pesticides & ToxicSubstances Branch.
Due to the scope ofremedial work anticipated to investigate and clean up PCB contamination in soil and groundwater and building interiors, it is appropriate that the Unimatic site be proposed for the NPL.
DEP appreciates the opportunity to participate in the decision-making process to nominate this site for NPLstatus and is lookingforward to future cooperation with EPA duringremedial work at the site.
Ifyou have any questions,pleasecall me at 609-2
