Notice
EPA is releasing the draft document, Problem Formulation for Human Health Risk Assessments of Pathogens in Land-applied Biosolids (External Review Draft), as announced in a September 19, 2008 Federal Register Notice, for public review and comment.
This is a draft document and as such has not been formally disseminated by the U.S. EPA; it does not represent -and should not be construed to represent - any U.S. EPA policy or determination. Under applicable information quality guidelines, the document is being released for a 45-day public comment period.Background
In 2002 the National Research Council released a report entitled, Biosolids Applied to Land: Advancing Standards and Practice. To address the issues raised by that report, in January 2004, EPA released an "Action Plan" for setting new priorities for the biosolids program. This draft document is an important step in that action plan because it provides concepts and planning methods for consideration and possible use in the conduct of risk assessments focusing on pathogens in land-applied biosolids. The document summarizes the existing literature; defines critical pathogen stressors; develops conceptual models linking the most likely stressors, pathways and health responses of concern; evaluates the overall quality and utility of available risk assessment data, tools and methodologies; and outlines an analysis plan that identifies research and methods for conducting a scientifically defensible risk assessment relevant to EPA’s decision needs.
History/Chronology
