Mr.Wayne Rosenbaum Page 2 The chrome levels from the SPLP procedure were ND (Not Detected below indicated detection limit.) For all practicable purposes,this indicates that no chrome was found in the leachate. 3. The raw material used by Nexframe is provided by Nexcoil Inc. A Metallurgical Test Report for the incoming raw material is provided for each batch of incoming raw material. As can be noted from the attached Metallurgical Test Report the amount of chrome contained in the raw material is 0.01% (1 part in 10,000). The material sampled in the trash can reference sample is reported to have contained 2,600 mg/Kg (26 parts in 10,000). The material sampled in the trash can contains 26 times more chrome than stated in the metallurgical certification for Nexframe's raw material. 4. It should be noted that for the other two sample analysis,performed by DTSC on the same day that the Nex02 sample was collected, indicated the levels of chrome, in the collected samples,were well below the chrome concentrations found in the trash can sample,Nex 02. Sample Nex01, collected by DTSC, from a gray colored powdery wash down material leading to a storm drain had a chrome concentration of 790 mg/Kg. Sample Nex03,taken from residue inside of the floor sweeping machine was found to have a chrome concentration of 1,100 mg/Kg. Summary: 1. Raw materials used in the manufacturing processes do not contain a sufficient quantity of chrome to produce a violation of the TCLP limit as evidenced by an ELAP Certified Analytical Laboratory SPLP chrome analysis, and the metallurgical test report. 2. The material collected from the floor sweeping machine used on the factory floor and the outside parking lots did not have sufficient chrome concentrations to exceed the TCLP limit as evidenced by DTSC test data. 3. The small amount of the material collected from the garbage can is characterized in the referent document as, "The inside of the garbage can is almost empty except for general garbage and some powdery residue at the bottom."should not necessarily be considered as a process waste stream. The garbage can contents are more consistent with an unsupervised non process related waste disposal. It is entirely possible that the small amount of material found to have a potentially hazardous chrome concentration could have originated from a source totally unrelated to the manufacturing operations of Nexframe. Conclusion: 1. No chrome source has been identified in the manufacturing operations or raw material utilized at Nexframe.
