MEMORANDUM TO: Phyllis Harris, Finance Department :.., I `� 4 FROM: Debbie Adamski, Building Services RE: Clean Water Services EDU Fees DATE: 8/5/05 This is regarding the issue of invoicing Clean Water Services for the 20% of the sewer EDU charge related to their Phase 4 Expansion of the Durham Treatment Plant. The plumbing work that is being done generated a 2.5 EDU increase, for a total of $6,500. 80% of this is $5,200 and 20% is $1,300. I have spoken with Monte Akers(sp) at Clean Water Services and he said they are going to waive their portion of the fee. We are to invoice them for our 20 %. I have left a message with Monte to give me a call back and let me know who to direct the invoice to. At this time I have not received a call back. I will be on vacation all of next week, so if you need to call him, his phone number is 503 - 681 -3640. The plumbing permit number is PLM2005- 00080(permit that generated the fees) The sewer permit number is SWR2005- 00066(permit that we are collecting the fees for) Attached is a copy of the sewer tally worksheet, the fee sheet and the activity list from the sewer permit. Hopefully this is everything•you need to prepare the invoice. If you have any questions, Dianna Howse is also familiar with this issue. Thanks!! .:.....
