Tennessee is open for business! At TDEC we firmly believe that environmental protection and economic development go hand in hand. We even take this idea a step further and assert that the strong economic development trends Tennessee is experiencing would not be possible without a highly functioning environmental regulatory system that delivers environmental protection, resource abundancy and excellent quality of life. TDEC is a resource to you, not just a regulator.
