In 2009, Robins received EPA's Design for the Environment Program recognition for use of PreKote on C-5s and C-130s cycling through the base for programmed depot maintenance.
On July 26, EPA issued similar praise for Robins' use of the substance on C-17s.
"EPA applauds Robins for taking steps to use 'green' alternatives to safeguard human health and protect the environment," Carol Kemker, deputy director of EPA's air, pesticides and toxics management division, is quoted in a base press release.
"Under the DFE program, the base has done a wonderful job of continuing to push for changes that result in the responsible care of the environment," Kemker added.
According to the Robins press release, PreKote is used instead of Alodine, a substance that contains chromium. The new solution is a water-based, mild-alkaline solution that "promotes paint adhesion, but is nontoxic, biodegradable and eliminates the use of hexavalent chromium."
