2.1.1 Narrative
No clean up work will be conducted on site between December 24th and January 5th. Security will be present on site. EPA will conduct periodic monitoring at the site over the shut down period.
2.1.2 Response Actions to Date
From December 15 - 22, 2014, work focused on the following activities:
Operations
- Completed bucket tests of samples combined from select staged containers (non-empty drums, buckets & totes). No adverse reactions were observed. Shipped combined samples for analysis;
- Continued consolidation of dross/smelting waste from across the site, and decontamination of foundations/pits/bins. Excavated waste was consolidated into waste piles #4 and #5. Foundation decontamination is estimated to be 90% complete.
- Continued sorting non-conforming debris from large dross/smelting waste piles and shaping piles. Work focused on sorting non conforming debris from Pile 5. Piles 1, 2 & 4 are ready to ship for disposal. Pile 3 also contains non-conforming debris which needs to be further sorted prior to sampling & characterization for disposal;
- Completed repackaging known baghouse dust waste in compromised supersacks into shippable supersacks, and staged sacks for disposal. To date, 49 bags have been repackaged, 13 were already in shippable condition and did not needed to be repackaged;
- Continued temperature monitoring of waste piles & supersacks of baghouse dust; and
- Began transportation & disposal of dross/smelting waste from waste pile 1 to the disposal facility. An initial shipment of waste was successfully completed on 12/18/14. Waste is being shipped daily on weekdays unless there is a significant chance of rain predicted at the disposal facility. (This waste cannot be disposed of during rain events due to its potentially water reactive nature). Waste shipped off site is cataloged in the progress metrics table below. To date, 14 loads of this waste weighing approximately 374 tons have been shipped for disposal.
Air Monitoring
- Continued implementation of the air monitoring plan to ensure public and worker safety.
- Continuously monitored data from particulate and chemical monitors for compliance with established standards. Real-time data are transmitted back to the site command post where they are monitored continuously. Any exceedances are addressed immediately.
- Maintained a website (VIPER) with current and past perimeter air monitoring data. See Section 6.1 for instructions on accessing the website.
Particulate Air Monitoring:
Datarams (DR4) are deployed daily at four fixed locations in each direction along the site perimeter boundaries where off-site receptors are most at risk to exposure from fugitive emissions. The perimeter action level for PM-10 particulates has been set at a time weighted average (TWA) of 150 micrograms per cubic meter (μg/m3), as established in 40 CFR Part 50, National Ambient Air Quality Standards (NAAQS).
One personal data ram (PDR) particulate air monitor is deployed daily in the work zone during the removal action. The particulate monitor will data-log instantaneous TWA particulate concentrations during active operations. Action level exceedances will be managed by setting the monitor to alarm at the established action level to notify on-site personnel. The particulate action level within the work zone has been established as 2.0 mg/m3 for the respirable fraction of total particulates. This is a site specific action level based on a calculation of airborne dust concentration.
During the reporting period, one brief exceedance of the perimeter action level for particulates was detected, but the TWA was not exceeded.
MultiGas Air Monitoring:
AreaRAE multi-gas monitors are being deployed at the container staging area and at 3 perimeter locations. The AreaRAE multi-gas monitors will be used to monitor ammonia in parts per million (ppm), hydrogen sulfide (ppm), VOCs (ppm), and percent lower explosive limit (LEL).
The perimeter action levels are as follows: ·
Ammonia = 10 ppm
Hydrogen Sulfide = 10 ppm
PM10 particulates = 150 micrograms per cubic meter (μg/m3)
LEL = >5%
VOCs > 5 ppm
Work zone air monitoring results are being compared with the National Institute for Occupational Safety and Health (NIOSH) 10-hour recommended exposure limit (REL) or the OSHA 8-hour time-weighted average (TWA) PEL, whichever is more restrictive.
A MultiRAE Plus 5-gas monitor (loaded with sensors for detection of oxygen, carbon monoxide, hydrogen sulfide, LEL, and VOCs) will also be used to periodically spot check AreaRAE data. Personal ammonia and hydrogen sulfide taht alarm when action levels are exceeded also being utilized in the work zone.
During the reporting period, only occasional brief exceedances of the perimeter multigas action levels were recorded. No exceedances of work zone action levels were detected.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
General notice letters were issued to current and former owners of the property. Investigation is ongoing.
