EPA is seeking more experts to consolidate and speed its peer review of models developed to better explain the health effects of the rocket fuel ingredient perchlorate, which EPA promised to regulate in drinking water in 2012 but has since missed statutory deadlines to do so - prompting advocates to sue to force a regulation. In a June 3 Federal Register notice, the agency says it is "expanding the scope" of an earlier request for nominations for peer reviewers of the model, published last March, that sought nominations for experts to peer review the biologically based dose-response (BBDR) model next fall as well as a draft model support document. In the notice, the agency asks for additional nominations to be submitted by July 5 for experts who can "review... the application of the draft [BBDR] Model to develop a perchlorate maximum contaminant level goal."
