2.1.1 Narrative
Cleanup continues.
2.1.2 Response Actions to Date
During this reporting period sampling of all of the identified drums and containers (with the exception of those in the labs for which disposal will be subcontracted out) has been completed. To date, 1123 samples have been haz catted. Based on these results, materials are being marked and staged with compatible wastes for bulking prior to disposal. All of the containers outside in the yard were sampled and analyzed, and after approval by the City this liquid (primarily rain water) was discharged to the sanitary sewer. Due to the poor condition of the building (leaking roof, etc.) water builds up in the sumps and on the floors after heavy rains. This sump water continues to be pumped from the building into two holding tanks onsite awaiting offsite disposal.
All containers of flammables above 1 gallon were bulked into two totes. Caustic materials are also being bulked into totes. Two rolloffs of non hazardous debris (the most recent shipment consisted mostly of RCRA empty drums and containers) have been shipped offsite for disposal. One rolloff of hazardous debris (contaminated cinder blocks and other contaminated materials) has been shipped offsite for proper disposal. All disposal facilities are checked for compliance status to ensure that they meet all environmental regulations before wastes are shipped.
Subcontracts for disposal of the lab materials, the sump water, and the overpacked cyanide salts have been awarded. These materials will be shipped offsite as soon as approvals are in place and transportation can be arranged.
Air monitoring/dust sample results have been received and are being evaulauated. Air monitoring throughout the building is conducted on an ongoing basis. Five air monitoring units are set up while work is ongoing: three inside the building and two outside. Volatile organic compounds, oxygen, lower explosive limit, carbon monoxide, hydrogen cyanide, and chlorine are monitored on a continuous basis, and any alarms are sent out to the OSC and contractors monitoring the system.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
Research on PRPs is ongoing.
