Makes no sense, but reconfirms an industry strategy to manipulate legal norms such that extraction is not ultimately threatened; and, as in this case, that potential resistance is frustrated by
the
de facto "legality" secured by drilling prior to disclosure. Turns transparency on its head.
Companies drilling for oil and gas on public lands must now identify the chemicals used. But in a concession to the industry, they do not have to make the disclosure until after drilling has begun.
