2.1.1 Narrative
EPA has transitioned from the Emergency Response Phase of the project into the Time-Critical Removal Phase. However, the dangers at the Site continue to pose an immediate threat to human health and the environment. The current focus at the Site is to mitigate the immediate threats of release from the Site to off-site migration pathways. EPA's estimated time to complete the removal is approximately April 30, 2012.
2.1.2 Response Actions to Date
To date the following response activities were completed during this reporting period:
Activities performed during the week of March 26th:
- ERRS contracter transported off-site Stockpiles #22 and #24 for a weekly total of 664 tons of arsenic contaminated soils.
- OSC, RM and START met with USACE personnel to discuss stream restoration plans.
- ERRS began final grading of western portion of site.
- A sample from the treated stockpile #23 was sent for TCLP analysis.
Activties performed the week of April 2nd:
- ERRS contractor received TCLP results from treated stockpile #23 for cadmium at .0070 mg/L.
- ERRS contractor began disposal of treated stockpile #23 for a weekly total of 649 tons of arsenic contaminated soil.
- START contractor placed erosion control mats and planted vegatation along the western and eastern sides of the stream bank per the stream restoration plan.
- START contractor has planted selveral pines along the western boundary of the site per the stream restoration plan.
Analytical Results of Stockpiled Material that failed the TCLP limit for non-hazardous waste of 1. mg/L for cadmium. Soil above this limit is considered hazardous waste and must be treated before it can be disposed in a Subtitle D Landfill. The treatment standard for cadmium is .11 mg/L or an alternative treatment standard of 90% reduction of the initial TCLP value and below 1.0 mg/L, in order to meet the Land Disposal Reguirements for Subtitle D Landfills.

2.2.1 Anticipated Activities
2.2.1.1 Planned Response Activities
The following activities are planned during the next reporting period:
- ERRS contractor will continue load out of stockpile #23.
- ERRS will continue with site restoration activies.
- START contractor will conduct confirmation sampling under stockpile #23 and assist ERRS contractor with site restoration.
2.2.2 Issues
Now that all of the dangerous chemicals have been removed from the Site, EPA will focus on removing contaminated soils that contain arsenic. EPA will continue to work closely with local, state, and county officials throughout the cleanup process.
