As a scientist, I know that it can take years for meaningful results to be published. In addition, many critical findings from observational studies could not and should not ethically be attempted at reproduction in a randomized control trial. In other areas, I might agree with waiting for reproducible published findings, but the potential harm to the environment and to the public health from delaying an environmental response is too severe to justify delay. Beyond the scientific reasons to vote "NO", this smells like yet another attempt to weaken environmental regulations. Please continue to stand strong in defense of the EPA!
