This is probably one big factor behind the May 30th, 2018 EPA comment deadline: “The proposed rule includes a provision allowing the Administrator to exempt significant regulatory decisions on a case-by-case basis if he or she determines that compliance is impracticable because it is not feasible to ensure that all dose response data and models underlying pivotal regulatory science are publicly available… The agency requests comment on whether these exemptions are appropriate….” Comment to EPA here: https://www.regulations.gov/docket?D=EPA-HQ-OA-2018-0259

the researchers estimated that the radioactivity concentration would increase by a factor of more than five within 15 days as a result of radioactive ingrowth. They measured an increase in the decay products 210 lead and 228 thorium in the closed system, and they predicted that radioactivity would continue to increase for more than 100 years with the formation of the decay products 210 lead and 210 polonium.” (EHP, July 2015)

What’s NORMal for Fracking? Estimating Total Radioactivity of Produced Fluids

Naturally occurring radioactive materials (NORM) found in liquid wastes from hydraulic fracturing are an emerging environmental health concern.1 The heavily drilled Marcellus Shale, for example, contains isotopes of radium, polonium, and lead.2,3 However, the few studies that have focused on NORM in fracking wastewater (produced fluids) have reported on a…
