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 5th:
- ERRS contracter transported off-site Stockpiles 19T, 15 and 21T for a weekly total of 1,391 tons of contaminated soil removed.
- START contractor conducted XRF screening the surface of Zone 6 and 7 where the stockpiles have been located to ensure that there were no residual contamination left behind. XRF readings in the area indicated levels in the range of 50 ppm to 122 ppm. The contamination was contained to the first 6 inches of soil. OSC tasked ERRS contractor to scrape the surface to that level in both Zone 6 and 7.
Activties performed the week of March 12th:
- ERRS contractor finished removing first six inches of Zone 6 and 7. The material from these areas became stockpile 22 and 23.
- ERRS contractor also finished excavating the pit that was located in the lean to area next to Building 1. The material from this area was placed in Stockpile #24.
- All zones that were initially sampled are clear of contamination and excavation operations have finished.
- ERRS sent waste samples from the three stockpiles for TCLP analysis.
- ERRS received the plants and trees that were outlined in the stream restoration plan.
- OSC and ERRS project manager (PM) met with a representative with SCDOT to discuss the conditions of Frontage Rd that leads to the Site. The SCDOT representative surveyed the road and came to the conclusion that the road did not require resurfacing but just minor patch work. He stated that his District Office will do the work for free.
Activities performed the week of March 19th:
- ERRS contractor received waste results and Stockpile #23 failed TCLP analysis for cadmium at 1.07 mg/L. This will require treatment of the stockpile with Free Flow. Because the value was so close to 1.0 mg/L requirement, ERRS ordered and received 20 tons of Free Flow 200 stabilizing agent instead of 200/300 mix.
- ERRS contractor disposed off-site 401 tons of contaminated concrete to a Subtitle D landfill. The concrete came from the chemical blending and biodiesel rooms in Building 1 and from Building 2.
- ERRS contractor started off-site disposal of Stockpile #22 and #24.
- ERRS contractor continues with grading western side of the property.
- ERRS contractor received erosion control mats and hyrdoseeding supplies.
- The OSC, ERRS PM and START personnel met on Site with USACE personnel to discuss 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 Treat Stockpile #23 with Free Flow 200.
- ERRS will continue with site restoration activies.
- START contractor will assist with the placement of plants and trees and the shaping of the stream bank.
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.
