the devil is in the details:
The secret science bill, for example, would apparently bar EPA from using public health studies based on confidential patient information, wrote the American Statistical Association’s president, David Morganstein, in a 25 February letter to lawmakers. That would force the agency into “a choice between maintaining data confidentiality and issuing needed regulations,” he wrote. Also, efforts to deidentify sensitive data before release—by stripping names and other information—aren’t fail-safe, Morganstein wrote.
Democrats are further concerned about another provision, not included in earlier versions, that would give EPA only $1 million per year to implement the bill, which would entail, among other things, obtaining raw data from study authors. The nonpartisan Congressional Budget Office calculated that the bill would cost $250 million annually to implement early on, and that’s only if EPA were to halve the number of studies it used to 25,000 annually, said Representative Donna Edwards (D–MD)
this bill is not even remotely about "transparency." it's about hamstringing the EPA.
