MN 15 Inspected by: Date of Inspection: 1.0 SUMMARY The tank requires a complete new interior and exterior coating. It appears the tank was last coated in 1982. The coating is failing prematurely. See photos in Appendix A. Structurally, the tank is sound. However, various structural modifications such as additional vents, manways and miscellaneous repairs are recommended. We recommend the seal welding of all internal seams below the high water line (HWL) which are not welded, as required by the American Water Works Association (A A)® Branch Office: 13807 Village Mill Drive Midlothian, Virginia 23113 804;379-3944 Fax 804-379-4693 Page 2 City of New Hope, MN AEC Project No. MN1057 It is estimated that the complete recoating plus the recommended modifications and repairs will cost approximately $351,000.00 and take 12 weeks to complete if there are no lead paint removal issues. These cost estimates represent the current pricing structure. If you plan to proceed with the coating of this tank, in order to obtain more competitive bids, the project should be bid at least nine months prior to the reconditioning date. The tank painting should be first inspected within the warranty period, and every three years thereafter. In our opinion, if all the recommendations are followed and the tank is inspected regularly, the new coating should last 15 to 20 years with only minor repairs. With proper maintenance, the tank will provide many years of service. 2.0 RECOMMENDATIONS The photographs referred to in this section are in Appendix A. All drawings are found in Appendix B. The surface preparation requirements for all repairs or new welding are described in Appendix C. The exterior paint chip lead test results are in Appendix D. Page 3 City of New Hope, MN AEC Project No. MN1057 2.1 Interior Structural 2.1.1 On the interior of the tank, weld the roof manway, the dry well tube and the dollar plate butt photos f 3. 2.1.2 Seal weld all bolted roof framing connections. After welding, remove all nuts and bolts. See photos 3, 4, and 5. 2.1.3 Seal weld the intermittently welded compression angles on the cone plates. Refer to photos 6 and 7. 2.1.5 Grind off all weld spatter below the High Water Level (HWL). See photos 10 and 11. This will require approximately 60 man hours. 2.1.6 Seal weld the intermittently welded stiffener angles on the dry well tube. There are two (2) stiffeners below the High Water Level (HWL). Refer to photo 12. 4 Page 4 City of New Hope, MN AEC Project No. MN1057 2.1.7 Remove the interior ladder on the dry well tube. It has been ice damaged. See photo 13. 2.1.8 Replace the two (2), 24 inch round manhole gaskets. One is in the tank bowl and the other is in the bottom of the wet riser. See photo 14. 2.1.9 Seal weld approximately seven (7) lapped seams on the interior of the wet riser. This is required by the AWWA D100 Standard. See photo 15. 2.1.10 Remove the ice damage handrailing around the top of the wet riser. See photo 16. 2.1.11 Install a toe or kick plate to both sides of the top platform in the dry riser. see photo 17. 2.1.12 Grind the welds on the exterior of the tank bowl plates. These are very poor quality welds and will cause premature paint failure. See photos 18 and 19. This will require approximately 60 man hours. Page 5 City of New Hope, MN AEC Project No. MN1057 2.2 Interior Wet Coating 2.2.1 The interior coating is in poor condition, 2.3 Interior Dry Coating 2.3.1 The interior coating on the dry surface areas is 2.3.2 Spot repairs to the interior of the fluted riser should be performed as required. Page 6 City of New Hope, MN AEC Project No. MN1057 2.4 Exterior Structural 2.4.1 Replace the tank vent/finial with a removable top mushroom vent, similar to the one shown on AEC drawing No. 6. See photo 25. The new vent and vent screen design should meet AWWA D100 and local Health Department Regulations. The removable top will improve ventilation and provide access to the tank interior during reconditioning. 2.4.2 Install three (3), 24-inch round, hinged roof manways, approximately 90 degrees from the existing manway. See photo 26. This will provide additional ventilation during the interior surface preparation and coating. See AEC drawing No. 7. 2.4.3 To prevent trespassing, install padlocks on the roof access manways. See photo 26. 2.4.4 Install a separate aircraft warning obstruction light bracket next to the roof vent and remove the existing light on the vent. See photo 25 and AEC drawing No. 8. 2.4.5 To bring roof handrail area in compliance with OSHA, a non-skid walkway is required for slopes between 5 in 12 and 2 in 12. Slopes 2 in 12 or less do not require a non-skid surface. Refer to photos 25 and 26.

Two possible alternates are: a. Rather than completely remove the coating, do spot repairs, clean the tank exterior, and add a new finish coat. b. Completely remove the exterior coat using a recyclable dry abrasive in a mini-mobile enclosures. This system operates under a negative pressure with a vacuum duct to the ground where the waste material is collected. The final cost of removing the exterior coating will depend on its hazardous nature and the removal method selected. 2.6 Cathodic Protection System 2.6.1 The corrosion and pitting that is occurring suggest that the C.P. system is not working correctly. If the system can not be maintained or operated properly, consideration should be given to removing it and welding the covers shut. Another alternative is to install a submerged C.P. system which is less susceptible to ice damage. 511 Eleventh Avenue South ENGINEERS & DESIGNERS Minneapolis.

To prevent oroduct contamination and to extend the service life of the vessel. linings are often applied to bring the corrosivity of the product on the vessel to a point that is low enough to be of no significance. As the corrosivity of the product increases. the design of the vessel becomes more critical. relative to the performance of the lining. Where a tank is to be lined for contamination prevention purposes only, certain compromises may be economicaily justifiable without sacrificing the lining performance. This revision of NACE Standard RP0178 -78 was prepared by NACE Task Group T- 6G -27, a component of Unit Committee T -6G on Surface Preparation for Protems Coatings, ano is issued under the auspices of Group Committee T -6 on Protective Coatings and Unings. The original RP0178 -78 was prepared in 1978 by Task Group T -6A -29 of Unit Committee T-6A on Coating and Uning Materials for Immersion Service in collaboration with Unit Committee T -6H on Application and Use of Coatings for Atmospheric Service (currently titled Coating Materials for Atmospheric Service) and was issued under the auspices of Group Committee T -6 on Protective Coatings and Unings. NACE Publication TPC e2, entitl "Coatings and Unings for Immersion Service," should be used as a guide for all areas of responsibility regarding coatings. This standard is issued to present recommended practices for the design, fabrication, and surface finish of metal tanks am vessels that are to be lined for corrosion resistance and to prevent product contamination. These recommended practices are considered nec- essary by lining suppliers, applicators, and users of such tanks through their experiences with them. Explanation is given as to how the suggested practices govern the quality of lining applications. Appendix A shows both good and bad design practices on tanks, while Appendix B contains a list of suggested responsibilities for the coating applicator to ensure the Ausisnom Morristown, NJ.
