However, various <br /> structural modifications such as additional vents, manways <br />. and miscellaneous repairs are recommended. <br />II We recommend epoxy caulking or seal welding of critical <br /> internal seams above the high water line (HWL) which are not <br />II welded. Although this is not required by AWWA (American <br /> Water Works Association) this will prevent rust streaking <br /> and extend the life of the coating. Also, we recommend the <br />. seal welding of all internal seams below the HWL Which are <br /> not Welded, as required by AWWA. Refer to sections 2.1 and <br />. 2.3 for specific recommendations. <br />.. We have done a total lead content analysis on the exterior <br /> and interior coatings. The results indicated a 4.6 percent <br />II lead content for the exterior dry and a 6.6 percent lead <br /> content for the interior wet area above the HWL. (See <br />. Appendix D) . Per current Minnesota Pollution Control Agency <br /> interpretations, the paint in these two (2) areas is <br />.. classified as lead based paint. Removal of lead based paint <br /> must be performed in accordance with applicable Federal <br /> (RCRA, EPA) and State (MPCA) regulations. Reconditioning <br />II specifications must be designed to include full containment <br /> and provisions to eliminate generating hazardous waste. <br />. <br /> We' have done a total lead content analysis on the interior <br />. wet coatings below the HWL. The results indicate a <br /> 0.2 percent lead content. Per current Minnesota Pollution <br />I Control Agency interpretations, the interior wet area below <br /> the HWL is not classified as lead based paint. <br />.e <br />. <br />
