Additional information requested <br />Reporting of PCB Analytical <br />Results <br /> What sampling grid methods are being considered on site? <br />How were the locations chosen? <br /> <br /> Non‐liquid PCB concentrations must be reported on a dry <br />weight basis as micrograms/gram (or milligram/kilogram) <br /> The PCB regulations require the use of the Ultrasonic <br />(EPA SW 846 Method 3550C) or Soxhlet (EPA SW‐846 <br />Method 3540C) extraction methods <br />Professionals involved onsite  What consultant professionals will be involved on site? <br />Will the AGI personnel visually classifying type of <br />material have the appropriate experience to do the work? <br />Considerations for nearby <br />receptors <br /> Contamination due to transport on site <br />o Refer to Current Conditions Report to locate <br />commonly used pathways. Please propose how <br />roads will be addressed on site via trenching, <br />boring and/or surface samples. <br /> Sensitive receptors <br />o How will nearby communities be affected by work <br />done on the site? Are these communities know to <br />be strong receptors of negative environmental <br />impacts (e.g. dust migration)? <br />o Where will the soils be disposed of at? Are there <br />communities of concern along the path to get to <br />the disposal facility? <br />Other  Trenching Scope of Work is attached to Figure 1. It states <br />its attached to Figure 2. <br /> <br />
