2. Approval of Minutes – May 24, 2016 – Long Range Planning Committee

NBC Chairman Mesolella asked for a motion to approve the May 24, 2016 Long Range Planning Committee meeting minutes as written. Commissioner Burroughs moved to approve the minutes of the May 24, 2016 Long Range Planning Committee as written. Commissioner Handy seconded the motion. The vote taken by the Long Range Planning Committee was unanimous. The motion carried. 3. Items for Action

A. CSO PHASE III UPDATE

Mr. Marshall advised the Committee that over the last year MWH (who has been acquired by Stantec) and Pare Engineering one of our local firms, have been working on optimizing our Phase III program to try to get the most “bang for the buck” and address as well as they can the affordability issues for the ratepayers. The Committee today will be hearing what they have achieved, where we have been, where we are now and where we are going. Also, at today’s CEO Committee meeting there is an action item for the additional funding for the next level of work for CSO Phase III and at today’s full Board meeting this presentation will be given again so the entire Board of Commissioners get to hear where we are and also act on the matter that will be before CEO for additional design funds. Mr. Marshall introduced Sean Searles of Stantec and advised that he would be making the CSO Phase III Update presentation before the Committee today. Attached is the Stantec’s presentation. After the presentation there was a lengthy discussion between the Committee members, NBC staff and Stantec staff regarding the optimization of the CSO Phase III project, the reduction in cost that could be achieved with the optimization of the project and the improvement in water quality vs. ratepayer affordability issues. 4. Other Business None. 5. Adjournment A motion to adjourn was made by Commissioner Nathan, seconded by Commissioner Burroughs and the Long Range Planning Committee meeting adjourned at 9:40 a.m. Respectfully submitted,

Raymond J. Marshall, P.E. Executive Director/Secretary
