<br /> <br />3.8 Exterior <br />Coating <br /> <br />3.8.1 <br /> <br />The coating Dry Film Thickness (DFT) on the exterior varies from 8,8 to 24.4 mils with <br />an average of 14 mils DFT. See photos 24 thru 28. <br /> <br />It appears that the tank was last coated in 2013. The exterior coating applied is not <br />classified as a lead based paint. Itis in excellent condition and no repairs are <br />required at this time. <br /> <br /> <br />3.9 Site and <br />Environmental <br />Considerations  <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />3.10 Antenna <br />Considerations <br />3.9.1 <br />No recommendations are made at this time. <br /> <br />In conformance with Minnesota State Rules Chapter 7025 and Federal USEPA Rules <br />for air quality and control of dust and fugitive emissions, a risk factor analysis has <br />been performed to determine the class of pollution control required for the tower <br />during reconditioning. The risk factor is a calculation of potential risk for the structure <br />and the values in the table of Subpart 3 (of the standard) are the standards of the risk <br />factor for the surrounding properties. The class of pollution control required for <br />compliance with the rules is Class H, which requires full containment. <br /> <br />3.10.1 <br />There are 2 providers on the tower currently. T-Mobile is on the fluted column and <br />Sprint is on the handrail. Wireless Communication antennas located on the fluted <br />column and on the roof hand railing. The Sprint antennas located on the roof have <br />issues as the upgrade was started and the contractor left the site and never returned. <br />There is a punch list of items that never were completed. Sprint was purchased by T- <br />Mobile in 2021 and is now removing the antennas from towers with colocations with <br />Sprint. These coating repairs should be completed when Sprint removes their <br />antennas.
