For the operational period of 12/19/11 – 12/21/11, U.S. EPA completed lab packing a total of 341 unknown small-quantity containers for disposal.  All hazard categorization (Hazcat) samples were returned to source containers and empty laboratory glassware was consolidated within 55-gallon drums for disposal.  Debris within the building interior was swept and staged into piles and drum/container locations were mapped.  Small over pack pails from the building were removed and placed inside conex boxes, large tanks were removed and staged outside and the site prepared for temporary shut-down to await for disposal approval. 

During the temporary shutdown, U.S. EPA completed drum inventory, generated shipping labels for all packed waste, drafted invitation for disposal bids (IFBs) and provided full-time security accompanied by routine site checks by site personnel.

On 01/09/12 U.S. EPA returned to site to conduct full time removal activities.  U.S. EPA activities conducted between 01/09/12 – 01/13/12 were comprised of removing debris from building interior and the cutting/crushing of RCRA empty drums and containers, with a total of three 20 CY roll offs of non-hazardous debris shipped off site; large metal tanks were removed from interior of building, decontaminated, dismantled, cut up and recycled.  Two previously unidentified 55-gallon drums were discovered buried in debris.  They were sampled and hazacatted for disposal.  Thirty drums/containers of hazardous materials were transported and disposed of at an U.S. EPA approved disposal facility, in addition to three compressed gas cylinders containing hazardous and poisonous materials. Disposal bids for remaining compressed gas cylinders were sent to vendors and ‘fine’ sweeping of interior of building was completed. Site was then prepped for a temporary three day shut down.

From 01/17/12 – 01/20/12 U.S EPA completed transport and disposal of 18 non-hazardous drums; 7 compressed gas cylinders containing hazardous, poisonous and/or toxic gases; prepared, labeled and disposed of 130 lab pack drums.   Completed final decontamination of site equipment as needed, demobilized site infrastructure and secured building entrances accordingly.

On 01/23/12 U.S. U.S. EPA completed a final restoration/grade of property topography where site infrastructure was formerly located. 

During all on site removal activities, U.S. EPA conducted both site and site perimeter air monitoring for contaminants. No readings above action levels were recorded.
