Good morning Elizabeth,
Thank you for sending me this monitoring information! Can you explain why outfalls B3, C, D, and E have no recorded
flow for 10 consecutive years? If this is really the case, you may want to contact DEMLR Regional Office Staff and ask
them to help you reevaluate whether these are actual outfalls.
To address the topics of our phone conversation on Tuesday:
1. 1 have revised the DAK America draft to exclude TSS. That monitoring parameter was not included in the 2010
permit and there is no reason to include it as a new parameter at this time.
2. 1 have attached our benchmark rationale and table. You made a really good catch with 1,4 Dioxane. I assumed
the 0.4 mg/l that was listed as the benchmark value in the old permit had just been revised to 0.73 mg/l in
2013. Since the receiving water for the permitted facility is a water supply, the concern is for chronic exposure
and the original value (0.4 mg/1) came from the EPA Drinking Water Standards and Health Advisories Table. I
have attached the 2018 edition and updated the permit to reflect this.
3. We don't have "fact sheets" for the permits, but I do have Staff Review and Evaluation Documents, which I have
been told are as close as we have to an equivalent. These are also attached.
4. Regarding the removal of BOD, with the limited monitoring data available and with the consistent elevation into
Tier II monitoring because of BOD benchmark exceedances in B2, it is extremely unlikely that a case can be
made to have this monitoring parameter removed from the permit. However, I am still in contact with the
DEMLR Regional Office Staff about this and can keep you updated with their decision.
Let me know if you have any other questions!
Thanks,
Lauren
