• 2.1.1 Narrative

• On January 2, 2012, EPA's contractors mobilized to the Site from the Holdiay break. Site activities were resumed on January 3, 2012.  

Activities performed during the week of January 4-7

• The Toxicity Characterists Leaching Procedure (TCLP) test results for cadmium of stockplie #1 that was treated before the holiday period did not meet the treatment standards of .11 mg/L for cadmium.  ERRS contractor consulted with a Free Flow representative to determine possible solutions. Based on the mixing calculations, the Free Flow representaive determined that the mix rate was below the 5% recommended rate. He also recommended a different Free Flow mix that is composed of 80% Free Flow 300 and 20% Free Flow 200. ERRS adjusted the treatment mixing procedures and applied it at the 5% rate on stockpile #7.  Stockplie #7 and #1 have similar TCLP values, 3.43 mg/L and 3.61 mg/L, respectively.  Results from the treatment of stockpile #7 were .019 mg/L and were below the treatment standards.  Based on these results, ERRS will repeat these procedures with the rest of the contaminated material that failed TCLP for cadmium and retreat stockplie #1. 
• Disposed off-site 496 tons of non-hazardous contaminated soil at Subtitle D Landfill. 
• Removed used batteries, tires and fire extinguishers that were found on Site and were sent for recycling.  
• Rinsed steel drums and prepared them for disposal.  
• Final preparation of Buildng 1 for demolition. 

Activties performed the week of January 9th

• ERRS contractor demolished Building 1 on January 12 and 13th and the metal was segregated for recycling.
• START contractor has an asbestos inspector certificate and was assessing the demolition debris for asbestos suspect material that was not visible during the initial asbestos inspection.
• ERRS subcontracted with a crane company in order to move a large piece of equipment from inside Building 1. The equipment weighed approximately 30,000 lbs and was in area that the concrete floor had to be removed. The owner/operator took the piece of equipment and sent it to a metal recycler. 
• ERRS contractor fixed silt fencing in order to maintain effective erosion control. 

Activities performed the week of January 16th

• ERRS contractor started with the removal of concrete floor in Building 1. START contractor is obtaining XRF measurements from the soil under the concrete area as it gets exposed.
• The soil in soutwestern corner of Building 1 had arsenic and cadmium levels of 2,311 ppm and 5,426 ppm respectively. This area was associated with a nearby septic tank and was under the chemical blending room of the building. 
• On January 18th, a drum with a blue substance and solid material was found buried in the soil under the area of the building that was under a lean to shed that was attached to Building1.  START took a XRF readings of the solid material inside the drum and found arsenic readings at 1,688 ppm.  START took a sample of the blue substance and applied pH paper to it and it indicated that material was an acid.  OSC Franco and START obtained photo documentation of the drum. ERRS overpacked the drum, moved it to a secure location within the Site and took a sample for disposal purposes. 
• ERRS continued excavating in the area where the lean to shed was attached to Building 1. This area of Building 1 was a migration pathway from inside the building all the way to the nearby stream. The roof had holes and rainwater was entering the building and existing through the compromised floor and outside the building. The soil in the area under the caved in floor had arsenic values up to 4,060 ppm, and cadmium values of up to 1,068 ppm.  The cement slab had arsenic and cadmium readings of 9,414 ppm and 1,996 ppm, respectively. 

Activities conducted week of January 23           

• ERRS continued removing the concrete and START continued taking direct reading measurements of the soil.  
• ERRS disposed of 564 tons of non-hazardous contaminated soil at a Subitle D Landfill. 
• OSC Franco received approval for a Action Memo ceiling increase of $800,000.  The new ERRS contractor ceiling is $2.4 million dollars. The ceiling increase request was due to a larger amount of contaminated soil found on Site that resulted in higher disposal costs.  

2.1.4 Progress Metrics

• Finish removing concrete and characterize soil under building 1.
• Continue treatment of contaminated soils that failed TCLP for cadmium.
• Prepare stream and property restoration plan for area disturbed on Army Corp of Engineer property.
• Continue off-site disposal of non-hazardous contaminated soil in a Subtitle D Landfill.
• Continue to maintain silt fencing.
