Hi Jodi,

Hopefully you received my last email regarding the stormwater question. To issue the NFA, I’ll need to answer the two pieces:

  1. Stormwater pathway - as described in my last email sent 2/8/23, via an updated current stormwater pathway evaluation, which includes all the current structures, improvements, land uses, conditions, etc.
  2. PCB question. Which you may already have the answer to. This question arose when I emailed you the DEQ Data Gaps memo last week. It states in your Phase 1 report on page 7, 2nd bullet: “additional soil sampling performed in 2000 of surficial and subsurface soils did not identify PCBs or metals above cleanup levels or background levels”

 

I was not able to find this report, however, I did find the two documents (attached) that suggests the PCB sampling was performed. I see the lab results but no report and none of our files have this report. The results suggests the PCB concentrations are favorable and non-detect, but there is no writeup of where the sample locations are, how deep, methods, etc, and any conclusions the contractor had. If you could provide that report, then I will be able to evaluate this piece, and potentially it would satisfy the question in the DEQ data-gaps memo.

Let me know if you’d like to discuss on a call. Thanks, Ray
