FracFocus has been offered up by industry and government officials alike as the model of transparency and the solution to chemical disclosure around hydraulic fracturing. But there are egregious shortcomings in FracFocus reporting by drilling companies, and in FracFocus disclosure policies. This report from Bloomberg and this blog post by NRDC's Amy Mall are must-reads that provide the particulars.
Voluntary reporting and self-policing do not work, and serve only to further public angst about unconventional gas exploration. It does the industry no good, and it certainly does not provide the public benefits claimed.
There is no substitute for government regulation and laws requiring full transparency about the gas industry's chemical use.
