The review is limited to the design of this particular project only, and does not cover the plumbing within the building. The review is based upon the supposition that the data on which the design is based are correct, and that necessary legal authority has been obtained to construct the project. The responsibility for the design of structural features and the efficiency of equipment must be taken by the project designer. Approval is contingent upon satisfactory disposition of any requirements included in this report. Special care should be taken to insure that the material and installation are in accordance with the provisions of the Minnesota Plumbing Code and applicable licensing requirements. Enclosed is a copy of the report and transmittal letter to be forwarded to the project owner. INSPECTIONS: All plumbing installations, including water service and building sewers,must be tested and inspected in accordance with the requirements of the Minnesota Plumbing Code. It is the responsibility of the contractor/installer to notify the Minnesota Department of Labor and Industry when an installation for a state contract job,licensed facility, or project in an area where there is no local administrative authority is ready for an inspection and test. To schedule inspections,contact the state plumbing standards representative for your region, or call Jim Peterson at 651/284-5889. REQUIREMENT(S): 1. AWWA C 900 PVC pipe may be used for the water service only if approved as an alternate material by the administrative authority(see Minnesota Rules,part 4715.0510 and part 4715.0330). 2. The PVC plastic pipe material to be used for the building sewer must meet one of the following ASTM Standards: D3034,F789,D2665,or F891. The installation must comply with ASTM Standard D2321 (see Minnesota Rules,part 4715.0530). Solvent weld joints in PVC and CPVC pipe must include use of a primer which is of contrasting color to the pipe and cement(see Minnesota Rules, part 4715.0810, subpart 2). 3. All joints and connections in the storm sewer system shall be gastight or watertight(see Minnesota Rules, part 4715.0700). Approved resilient rubber joints must be used to make watertight connections to manholes, catchbasins, and other structures. Cement mortar joints are permitted only for repairs and connections of existing lines constructed with such joints(see Minnesota Rules,part 4715.0750). 4. Draintile pipe which is directly connected to the storm sewer system is classified as storm sewer. Since all portions of storm sewer located within 10 feet of the water service must be tested,the piping located within 10 feet of the new water service must be hard piped,relocated, or removed. It must be verified that all draintile inlet elevations to the catch basins are above the storm sewer outlet elevations. / a Crystal Bay Business Center II, Service Connections Sewer and/or Water Service Connection Plan No. 087547 Page 2 August 5, 2008 5. Materials used for the subsoil (draintile)drains must comply with Minnesota Rules,part 4715.0620. No quality standard for this material is provided on the submitted plans. 6. Disinfection of the potable water system must include the following(see Minnesota Rules,part 4715.2250): a. The pipe system must be flushed with clean,potable water until no dirty water appears at the points of outlet; b. The system must then be filled with a water chlorine solution containing at least 50 parts per million of chlorine and allowed to stand for 24 hours; or a solution containing at least 200 parts per million of chlorine and allowed to stand for three hours; and c. Following the allowed standing time the system must be flushed with clean potable water until no chlorine remains. 7. The plumbing system shall be tested in accordance with Minnesota Rules,part 4715.2820. This includes all portions of the storm sewer located within 10 feet horizontally of the building or water service piping. NOTE(S): 1. This approval is for the site utilities only. 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.

The review is based upon the supposition that the data on which the design is based are correct,and that necessary legal authority has been obtained to construct the project. The responsibility for the design of structural features and the efficiency of equipment must be taken by the project designer. Approval is contingent upon satisfactory disposition of any requirements included in this report. Special care should be taken to insure that the material and installation of the plumbing system are in accordance with the provisions of the Minnesota Plumbing Code. A copy of the approved plans and specifications should be retained at the project location for future reference. A set of the identified plans and specifications is being returned to Voson Plumbing,Inc. Enclosed is a copy of the report and transmittal letter to be forwarded to the project owner. INSPECTIONS: All plumbing installations must be tested and inspected in accordance with the requirements of the Minnesota Plumbing Code. As specified in Minnesota Rules,part 4715.2830,no plumbing work may be covered prior to completing the required tests and inspections. Provisions must be made for applying an air test at the time of the roughing-in inspection as outlined in Minnesota Rules,part 4715.2820, subpart 2,of the code. A manometer test, as specified in Minnesota Rules,part 4715.2820,subpart 3,is required at the time of the finished plumbing inspection. It is the responsibility of the contractor/installer to notify the Minnesota Department of Labor and Industry when an installation for a state contract job,licensed facility,or project in an area where there is no local administrative authority is ready for an inspection and test.

The flammable waste interceptor outlet is more than 25 feet from a vented drain. Therefore,the discharge line must be provided with a 2-inch minimum vent pipe installed within 25 feet of the interceptor(see Minnesota Rules,part 4715.1120). This vent must not connect with the vent serving the flammable waste interceptor. b. The submitted plans do not appear to show a full-size vent stack.A full-size vent stack(3-inch minimum)must be provided for every building(see Minnesota Rules,part 4715.2520, subpart 1). This stack must be continuous in size from its base to its terminal and should be the most remote stack from the location where the building drain leaves the building.
