Cottage Grove, a city in Minnesota, awarded TMI Coatings the project of recoating the interior and exterior of their 1MG ground storage tank. TMI vacuum blasted the tank exterior, which kept dust levels low. By vacuum blasting the tank, MPCA and OSHA regulations are met. An abrasive sample was collected to test for heavy metals to ensure proper disposal. A three coat system was applied to the entire exterior.
The interior of the tank is considered a confined space. TMI blasted, collected another sample, and applied two coats NSF coating to the entire interior. The tank was washed out and disinfected and placed back on line. The work was completed safely in a timely manner.
