Hi Sarah,
I am forwarding two documents related to the draft conductivity guidance that we discussed when we met with you at the end of June. As we described, there are some significant scientific flaws associated with the draft conductivity guidance. Just leaving the guidance as draft, however, will not stop it from being used in actual permitting decisions or as a basis to pursue litigation. The Region V memo attached shows one example of an individual EPA scientist advocating use of the conductivity methodology in Region V (northeast Minnesota). The GEI Review, also attached, provides a detailed, science-based assessment of Susan Cormier's (U.S. EPA ORD) work, highlighting some of the key concerns with science behind this conductivity guidance.
We continue to be very concerned with how the draft conductivity guidance issued at the end of the Obama EPA is dealt with moving forward. As we discussed with you in our meeting, we would be very interested in meeting with OW Deputy AA Lee Forsgren and key OW managers/staff on conductivity in order to continue to raise our concerns on this matter. You told us in our meeting with you that you would like to join us if we went to meet with OW. If you would like this meeting to be set up through your office, that would work very well for us. Alternatively, I can reach out to DAA Forsgren's office to initiate plans for that meeting, making sure that you are included.
Thank you again, Paul
