Peer reviewers charged with commenting on EPA white papers examining sources of methane emissions from energy production are largely split on any policy outcomes and a host of other issues but they agree that the agency needs to improve its data, including by making greater use of data from its greenhouse gas reporting (GHG) program.
Risk assessment experts will hold a two-day meeting this week to peer review EPA's draft studies on the health impacts of two ubiquitous perfluorochemicals (PFCs) once used in manufacturing, but now considered potential carcinogens. Meanwhile, an EPA Science Advisory Board (SAB) panel is slated to hold an informal discussion of the agency's Clean Water Act (CWA) jurisdiction rule.
A panel of independent experts reviewing the EPA water office's draft assessments of the human health risks of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), are questioning some of the agency's core decisions for the quantitative risk estimates, though some reviewers struggled to provide alternate recommendations and instead called on EPA to better justify its analyses of the ubiquitous chemicals.
