2.1.1 Narrative
START along with ERRS continue to conduct activities to identify threats and contain potential uncontrolled releases.
2.1.2 Response Actions to Date
The following actions were completed during this reporting period:
- ERRS continued the destruction of poly drums, poly ASTs, vats and totes. The decontamination liquids were collected in onsite sumps within the building. The residual materials from these containers was neutralized using soda ash.
- ERRS continued to overpack any remaining deteriorated drums.
- START and ERRS worked to drill holes in the concrete floor in order to check the type of foundation and to collect soil samples underneath.
- The sludge that surrounded the acid totes was neutralized using soda ash and then placed into containers for disposal.
- DHEC personnel on site to observe field activities and coordinated future sampling with EPA.
- The steel frac tank has been decontaminated and removed from site. At this point all ASTs, frac tanks, and vacuum boxes have been removed from the Site.
- Incident: On July 29 while mixing some pH 7 and pH 10 liquids together for bulking, a reaction occurred producing a brownish-orange vapor cloud inside the building. Knowing the materials that were mixed, it was assumed to be a Nitrogen dioxide (NO2) plume. The crew was evacuated to the muster point and the AreaRaes onsite were calibrated to check for NO and NO2. A sensor was placed at the two main entry points to the building and at the fence before Manse Jolly Road. Then, fans were placed in the building to help ventilation and air sparging was conducted on the materials to accelerate the reaction. ERRS monitored the AreaRaes throughout the night and the readings fell below detection limits by morning.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
Coordination with EPA's attorneys on this matter continues. EPA has been in contact with the trustees and owners and has secured access from both.
