Plans and specifications for the interior portion of the plumbing system have been reviewed under Plan No. 087584. 2. As noted in the July 14,2008, letter from Evelyn Turner,City Planner for Orono,the city engineer has reviewed and approved the civil plans for the above mentioned project. Once the sewer,water,and storm drain have been constructed in a manner satisfactory to the City,the owner will grant the City utility easements. The City will then accept the improvements. Turner's August 5,2008,email to our office clarified that the City will own and maintain the sanitary sewer and water mains within the easements. The City will also own the storm sewer mains within the easements and will maintain them except for the four manholes that are part of the sediment control system. The owner will be required to maintain these. 3. The Minnesota Plumbing Code is available on our website at: www.doli.state.mn.us/plumbing.html Prior to the installation of additional plumbing,not covered by this review,plans and specifications must be submitted to and approved by this office. Authorization for construction in accordance with the approved plans may be withdrawn if construction is not undertaken within a period of two years. The fact that the plans have been approved does not necessarily mean that recommendations or requirements for change will not be made at some later time when changed conditions, additional information,or advanced knowledge make improvements necessary.
