On Thursday, August 23, 2007, U.S. EPA and its contractors mobilized to the Site to initiate the cleanup and removal activities. General Site set-up activities were performed to prepare the Site for work activity.
From August 24 through 25, 2007, general Site set-up activities continued. Utilities, including telephones and internet, were established. Safety controls were put into place around structurally unstable areas of the Site. Cleanup crew began clearing debris which surrounded future work locations to allow for safer access during sampling and removal activities.
On Monday, August 27, 2007, cleanup activities were initiated. The cleanup crew began clearing debris from around a large electrical bank in order to gain safer access during the removal of the capacitors containing polychlorinated biphenyls (PCBs).
On Tuesday, August 28, 2007, cleanup up activities continued. Debris was removed from a hallway to allow for easier access to the foundries former laboratory located in the central portion of the main building. All mercury containing thermostats from the buildings walls were collected and stabilized for future disposal.
On Wednesday, August 29, 2007, cleanup activities continued. Debris was removed from within the Quonset® building, where the majority of the Sites waste containers are located, to allow for better access to the drums, totes, tanks and small containers.
August 30 through September 3, 2007, no Site work occurred.
On Tuesday, September 4, 2007, cleanup activities continued. Once enough of the miscellaneous debris was removed from within the Quonset® building, the cleanup crew began stabilizing and staging the drums, totes, tanks and small containers for later waste characterization and sampling.
On Wednesday, September 5, 2007, cleanup activities continued. Sampling of waste containers within the Quonset® building was initiated. The initial sampling was done with the crew members under supplied breathing air in Level B personal protective equipment. The U.S. EPA Region 5 air trailer was used to supply the air to the sampling crew members during work activities within the established hot zone. START provided air monitoring during sampling activities.
On Thursday, September 6, 2007, cleanup activities continued. Level B sampling were was completed. Based on air monitoring conducted during Level B operations and drum investigations, the cleanup crew was able to continue sampling the remainder of the waste containers in Level C personal protective equipment (PPE). START continued to provide air monitoring during sampling activities. Any newly identified containers not already screened will have to be addressed in Level B PPE.
On Friday, September 7, 2007, cleanup activities continued. The cleanup crew continued sampling the waste containers within the Quonset® building. An estimated number of containers within the Quonset® building was calculated as follows: 350-Drums, 24-Totes, 6-Tanks, 400-Bags, and 120-Small containers (≤5 gallons). These are only the containers which were in this building, a sweep of other buildings and the rest of the property needs to be conducted. START continued to provide air monitoring during sampling activities.
