March 9, 2023 Northern Dewatering, Inc. 2 <br />NDI will return to the site at a later date and remove the temporary system. <br />City of Arden Hills Responsibilities <br />The City of Arden Hills ("City") will be responsible for the daily operation and <br />maintenance of the pumping system including changing air and fuel filters as needed <br />and oil changes every 250-hours. The City will need to arrange and pay for fuel for all <br />pumps and generators. NDI estimates the fuel consumption to be on the order of 65 <br />gallons per day per pumping location. <br />NDI highly recommends that the City man the pumping system 24-hours per day while <br />the system is in operation. NDI can provide an experienced pump operator for an <br />additional charge. <br />The city will be responsible for ensuring that the pumps and discharge pipe do not <br />freeze. If the pumps are operated during freezing temperatures and then shut off, the <br />pumps and piping must be drained completely. This may include, but not limited to <br />installing temporary shelters, tenting, heating, and placing ground thaw equipment over <br />and around the discharge pipes and pumps. <br />All excavation, backfill, and restoration associated with cutting down the existing <br />pumping structure, removing the cone section/top slabs or installing a temporary sump <br />structure will be by the city if needed (this is not anticipated at this time). The city will <br />also be responsible for all excavation and restoration work associated with burying or <br />blistering the discharge piping across roads, driveways and/or paths (including <br />trenchless methods if needed). <br />All confined space work associated with setting submersible pumps, or installing <br />bulkheads, temporary weirs, sandbags and/or pipe plugs will be by the city. <br />Bypassing or handling all lateral sewers, services and/or Vac Truck operations will be <br />the responsibility of the city. <br />The City's responsibilities will also include the following: <br />➢ <br />Flow measuring devices if <br />➢ <br />Permits of any type <br />needed <br />➢ <br />Bonds of any type <br />➢ <br />Source of water (for cleaning and <br />➢ <br />Bulkheading / Pipe plugs <br />testing) <br />➢ <br />Discharge Route <br />➢ <br />Access to site <br />➢ <br />State and Local Taxes <br />➢ <br />Dewatering if needed <br />➢ <br />Traffic Control <br />➢ <br />Emergency Response Plan <br />➢ <br />Restoration of any kind <br />14405 NorOdale Blvd-• Rogers.
