Using Dorothy Patton's presentation “Developing EPA’s peer review program” as a point of departure, this talk discusses EPA's progress over the past 2-3 years in enhancing the use of peer review for scientific and technical work products that inform Agency decision making. Specifically, this talk will cover: the increase in numbers of peer reviews at EPA, peer review as a cornerstone of EPA's Information Quality Guidelines, peer review in the Agency's decision process, and OMB's proposed peer review standards for regulatory science.
