*DRAFT BOARD OF SELECTMEN MINUTES 9-16-2019* 6 Board of Selectmen Minutes September 16, 2019 Alan McClennan: Presentation on the Town of Orleans' Experience Dealing with Develo ing a Plan for Wastewater Mang ement and Finance: (continued) Mr.McClennan indicated the Town of Orleans owns 24 acres near Exit 12. It is the site of a former Tri-town treatment plant. The Tri--town agreement was terminated and the plant has been demolished. In two weeks,the town is submitting 90% construction plans to DEP with construction anticipated to be completed in 2022 or 2023. Construction financing for wastewater is interest free. In the financing plan,payback would begin in 6 months after the start of construction. The Town of Orleans has secured grants for state improvements,road work in the downtown area. Engineering is complete. Town Meeting voted $3.8 million for pipe installation with no definitive answer on the specifics of the sewering. (25% of the design elevations, etc. were made known) Each October revenues are placed in a Stabilization Fund for wastewater use only. It is expected the Town will begin utilizing those funds in 2023. within the wastewater Capital Plan there is a need to go to Town Meeting to request funding for Phase II; Meeting Douse Pond where 100% of the nitrogen needs to be removed. The t^v v:rn X.r ll be requested t^fund a debt exclus�on,and ,t is antic pate[ t P rPClllt ng---ion�L oll be;positive. Mr. McClennan explained the wastewater project has always been a town project. The Town of Orleans has an internal water& Sewer Commission. It is projected that Cape towns above Orleans would utilize the system, and assist in the reduction of operating costs. Projects are eligible for 0% financing if a project is not subject to an enforcement order or a court order. Eligibility for 0%financing costs is a tremendous savings and should not be jeopardized. It is also important to have an approved CWMP. Or--leans falls in line with Provincetown, Chatham,Harwich and Mashpee. As the other towns gain approval of their plan,you may ask where you are in the que, and it is most favorable to be in the front of the que for funding. It was suggested the Town of Mashpee approach the use of the Cape Cod&Islands Clean Water Trust funds with principal forgiveness. It is important for a town to have clean water to remain as a place where people would want to be. Discussion followed regarding the use of wick wells,vertical wells for processing. Mr. McClennan indicated the Permeable Reactive Barriers (PRB's) an alternative method of collection is very effective. A PRB was installed in a parking lot at a bail field, a problematic area with excess nitrogen. Data is available from the three-year test. It is anticipated the Town of Orleans will place more PRB's in hot spot areas. As an alternative there has been an ongoing aquaculture experiment using shellfish. The Town took charge of the program for three years, and now a contractor is extracting the shellfish from the pond. It was noted the Town of Maslipee intends to process wastewater with a Membrane Bioreactor(MBR) as Orleans. This would allow for preliminary treatment, screening(1-3 mm) and grit removal and secondary/tertiary treatment MBR along with UV disinfection. The discharge limit is 10 ppn,but the plant may target operations at the nitrogen level of 5 ppm.
