.h, a x.111" The email from AGE states that they have updated the Site Specific Health and Safety plan for the excavation work and that the scope of work within a "HSP" is somewhat variable and designated personnel or staff might change with mobilization and that to that end, the operator of the excavation "tooling" is to be determined. AGE stated that the HSP is reviewed in the field and signed or "perfected" on-site, which is the typical use of a HSP. AGE stated that all workers will be 40-Hour hazardous waste operator trained, as required under the workplan. AGE stated that they attempted to clarify the "scope of waste disposal within the workplan." They stated that previous inspections might have depicted glass waste, however, analysis of the "subsurface soil column" (the report was attached and provided to the LEA for review) did not indicate a "considerable volume (vertically)" of waste glass debris; glass waste and random waste which is not glass rather trash or deconstruction refuse from the factory, will be disposed at a landfill. AGE stated that additionally, there were no concentrations of chemicals which could be characterized as hazardous waste. However, samples will be collected ("stockpiled waste is appropriated detected") to verify the findings of this proposed trenching examination and reconnaissance. AGE stated that attached are the two documents for the project. AGE was planning to schedule the investigation within the next three weeks. Comments: the wording in this email (e.g.,"subsurface soil column, random glass which is not glass rather trash or deconstruction refuse") is confusing). As previously indicated, it appears that documentation has not been presented to support the statement that "no concentrations of chemicals which could be characterized as hazardous waste." a — r i The LEA email thanked AGE for updating the Investigation Work Plan and Health and Safety Plan and reminded AGE to schedule with the LEA 48 hours prior to commencing the investigation. The email from AGE states that they have "prepared to examine / excavate the former waste management handling Area" 500 East Louise in Lathrop and that they will have Mr. Ron Barber from "L&B Enviro." AGE stated that excavations will start Monday 16 April 2015 and that they can leave open the excavation for LEA inspection and to please call "with your inspection expectations." Comment: Based on a Google search, L&B Environmental, Inc. is a contactor with experience/ expertise in environmental abatement and remediation (e.g., hazardous materials removal).
