Number:      Action Memo Date:   Response Authority: CERCLA    Response Type: Time-Critical Response Lead: EPA    Incident Category: Removal Action NPL Status: Non NPL    Operable Unit: Mobilization Date: 7/27/2015    Start Date: 7/28/2015 Demob Date:      Completion Date:   CERCLIS ID:    RCRIS ID: ERNS No.:    State Notification: FPN#:    Reimbursable Account #: 1.1.1 Incident Category CERCLA incident category: Inactive production facility 1.1.2 Site Description The Site is the former location of the Waunakee Alloy Castings Corporation which ceased operations in 2009. The Site contains one large main building where casting operations occurred and five smaller surrounding outbuildings that contain molds and other artifacts that were needed in the facility's processes when it was still in operation. A small office building is located hi the southwest corner of the Site. There are various hazardous material issues throughout the Site. 1.1.2.1 Location The Waunakee Alloy Facility is located in Waunakee, Dane County, WI. The site is an abandoned metal castings facility. The site borders a park and six mile creek to the south, Madison St to the west, and resident homes to the north and east.  1.1.2.2 Description of Threat The main contaminants are elemental mercury and PCB's (Aroclor-1248 and Aroclor-1254). The areas with the most significant contamination are the northern end of the main building and the voltage room. Flammable and corrosive chemicals were also identified on the site. 2. Current Activities   2.1 Operations Section     2.1.1 Narrative See POLREP #1 for a summary of the first week's activities.   8/3/2015 - 8/7/2015 On 8/3 START, EPA, and ERRS arrived on site to begin work where it was left off the previous week. ERRS began by continuing to remove waste containers found throughout the main building and stage them in the segregating area. on 8/4 ERRS began vacuuming operations in the main building to collect and segregate the foundry sand found throughout the facility, these operations continued through the end of the week. On 8/5 ERRS started the day by replacing the poly sheeting found in the decontamination area. On 8/6 ERRS moved their staging area and decontamination area from the east side of the building to the room (after START used LUMEX to confirm the room was clean) near the loading bay on the south side of the building.  START set up perimeter dust monitoring on the north, south, east, and west sides of the site each day with no readings above background. START also continued mercury assessment in the main building. This was done by using shrouds to cover the floor and then screen the air inside the shrouds to determine if mercury contamination was present on the ground. The mercury assessment of the main building was completed on 8/6. On 8/4 START conducted an asbestos survey of the site, there was no asbestos observed. On 8/6 START collected a sample from a sump discovered in one of the outbuildings. START also documented ERRS actions on the site. 2.1.2 Response Actions to Date See POLREP #1 for a summary of the first week's activities.   ERRS completed removing waste containers from the main building and taking them to the segregating area. ERRS began vacuuming and segregating foundry sands based on START mercury assessment findings. START continued, and completed, mercury assessment of the main building, conducted perimeter dust monitoring, and documented site activities. 2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs) 2.1.4 Progress Metrics Waste Stream Medium Quantity Manifest # Treatment Disposal                                       2.2 Planning Section     2.2.1 Anticipated Activities 2.2.1.1 Planned Response Activities ERRS will continues to remove debris and waste into the staging area. Hazardous waste is being put into cubic yard boxes in the staging area and will be properly disposed of after waste characterization is confirmed. ERRS will also remove foundry sand located throughout the building. START will continue to perform daily perimeter dust monitoring and conduct mercury vapor screenings of rooms as ERRS completes their cleaning. START will also continue to document and monitor site activities. 2.2.1.2 Next Steps Materials inside the buildings (Foundry sand/dust, drums, moldings, etc) will be put in the staging area and hazardous waste will put into cubic yard boxes to await disposal. Wastes on site will be sampled for waste characterization and then properly disposed of.   2.2.2 Issues   2.3 Logistics Section     No information available at this time.   2.4 Finance Section     No information available at this time.   2.5 Other Command Staff     No information available at this time. 3.
