Date: December 11, 2015 Project: 140 Riverbank Road Restoration Northampton, MA DEP Number # 246-0687 NEE Project Number – 15-4680 RE: Weekly Monitoring Report Week Ending 12/11/2015 The following activities where completed this week for 140 Riverbank Road. FRIDAY DECEMBER 4TH, 2015 While Scapes Building and Excavation (Scapes) was excavating the area for the new Septic tank, we discovered and old concrete foundation and slab around 40” below grade. Based on the dimensions for the proposed new septic tank, Scapes had to saw-cut and air hammer the area of the exposed old concrete foundation and slab away to make room for the new septic tank. The portion of the old foundation was cut, air hammered and removed from the site. During the excavation of the area for the new septic tank, it was also discovered that the water line from the street was not in the location as shown on the septic plans. This water line runs from the street to the northwest corner of the main house and then from the main house, and then a waterline runs from the northwest corner of the main house to the south west corner of the cottage. www.neeinc.com 2 (Photo showing the concrete slab and footing discovered while excavating the area needed for the installation of the new septic tank.) (Photo showing the concrete slab and footing that had to be saw-cut, air hammered and removed from the site to be able to set the new septic tank to the correct elevation.) www.neeinc.com 3 (Photo showing the water line on the western edge of the new septic tank that runs from the main house and feeds the cottage) SATURDAY DECEMBER 5TH, 2015 The new septic tank was delivered to the site and set in the excavated area adjacent to the existing functioning septic tank to minimize homeowners and tenant’s disruption of sewer services. The exterior of the new tank partially backfilled and site was stabilized for the remainder of the weekend. www.neeinc.com 4 (Photo showing the new septic tank being set in the excavated area adjacent to the current septic tank-in foreground of picture) MONDAY NOVEMBER 7TH, 2015 Scapes Building and Excavation (Scapes) excavated the area for the new septic pump tank. The base was filled with washed stone as specified for a setting bed for the new pump tank. www.neeinc.com 5 (Photo showing the excavated area for the septic pump tank) TUESDAY DECEMBER 8TH, 2015 New septic pump tank was installed and set in place as shown on the septic design plans. During the excavation of the trenches for the new alignment of the septic lines running to the new septic tank, it was discovered an additional foundation wall was in the path on the new pipe alignment coming from the cottage structure to the new septic tank. Again, we had to saw-cut this exposed old concrete foundation, air hammer the concrete and removed the debris from the site. Asphalt in driveway was saw-cut in preparation of connecting the new pump tank to the new septic field. www.neeinc.com 6 (Photo showing the installed septic pump tank installed to the west side of the newly installed septic tank) (Photo showing the old foundation wall unearthed while excavation the new trench for the septic pipe from the cottage to the new septic tank.

Septic pump was installed and wired by a licensed electrician. (Photo showing the new pipe out of the septic pump tank, across the driveway into the new septic field on the north side of the cottage) www.neeinc.com 8 THURSDAY DECEMBER 10, 2015 Northampton Electrical Inspector came to the site to approve the new electrical work for the septic pump. Upon inspection, the inspector noted that the service to the house and the existing electrical box located in the basement does not meet code and needs to be updated. The service from the pole to the house will need to be updated and the circuit box in the basement will need to be relocated out of the floodplain. This work is being coordinated and will be completed as soon as possible. The inspector allowed the electrician to temporarily hook up the new septic pump until the updates for the electrical work can be completed. Scapes disconnected to old lines feeding the old septic tank and installed the new pipes connected to the new septic system and field. (Photo showing the new pipe out of the cottage conned to the new septic system) FRIDAY DECEMBER 11, 2015 Septic designer completed the final septic inspection and approved the system. Scapes filled around all the new septic connection, tanks, and features. Scapes pumped down the old septic tank and will filled it with flow-able fill, to properly decommission the old system next week. www.neeinc.com 9 (Photo showing the new septic system partially back filled prior to final inspection by septic designer) ANTICIPATED TASKS FOR THE WEEK ENDING 11-18-2015 a.
