Title of Signing Page 2 of 6 FTSE 10-18 Hunkele, Dean From: Jim Craig <JCraig@sepiinc.com> Sent: Monday, July 1, 2019 3:47 PM To: Hunkele, Dean Cc: Lynn Vetter; Greg Thompson; Bernie Mowbray Subject: RE: [External] RE: BF #18 app Dean, We were recommending to re -permit the affected LS basins as the flow increases to require activation of the additional FM options. We found this to be prudent with the additional future growth as the planned increase in flow from other future station(s) south of the existing piping (such as the recently permitted WQ0040624-2/5/2019) would need to be addressed and modifications to the pumps (adding the third pump at LS#18) or further revisions to the FMs (LS#33) which currently utilize our recommended 10" routing. This will require further vetting during low flow startup period to optimize the system efficiency from the stand point of cycle/odor and require modifications of LS#10 firm capacity as the flows increase. No; the model calculated 1282GPM based on existing pump's curve (non -worn impellers) at LS#18 and which was supported by a recent drawdown. Yes; utilizing one of the existing 10" and both the new 10" and 16" from the crossing at Hwy 17 to LS#10 wet well — where the LS flows (LS#18, LS#33 and future) would merge and route to LS#10. The model's flow results for the pumps at LS#18 did not obtain the 1500gpm flows for the reroute to LS#10. It does not appear these pumps were ever capable of the 1500GPM pumping rate for the design system or the rerouted/modified system. Let me know if you have additional questions. James S.

I would assume the 1282-gpm rate would be using both force mains, but would it need different pumps or impellers? You say it can't pump at 1500-gpm with the current pumps, is that based on wear & it could with new impellers, etc or is it a bad design?

Please use the Department's Permit Application Tracker to determine the official application receipt date to allow you to estimate a date for issuance and find the reviewer's name. Once issued, the record stays on the site for 30 days. For previously issued sewer permit info or to check on sewer certification receipt status, please use the Division's Sewer Extension Permit Tracker. Using the Issue Date on top of the Engineer Certification Form is best way to ensure getting what you want especially for multi -version permits; using today's date only gives info on the latest permit version. Confirmation using this method will replace letters and emoils; it is recommended that confirmation be printed and/arsaved.

In orderto keep the flow moving at the current ADF we proposed to use 1 of the existing 10" pipes and the new 10" pipe to LS#10. As the flow may increase then TOL can activate the other existing 10" and the new 16" and eventually route through both 10" and the new 10" and 16". The maximum flow rate from LS#18 is expected to be 1282GPM@152FT, based on the model. In any event, the current permitted firm capacity of LS#18 1500GPM is not achievable with the existing pumps.
