Uniform Federal Policy for Quality Assurance Project Plans

The Uniform Federal Policy for Quality Assurance Project Plans (the UFP-QAPP Manual), prepared by the Intergovernmental Data Quality Task Force (IDQTF), provides instructions for preparing Quality Assurance Project Plans (QAPPs). The UFP-QAPP Manual was developed IDQTF, a joint initiative between the U.S. Environmental Protection Agency (EPA), the Department of Defense (DoD), and the Department of Energy (DOE). The purpose of the Manual is to provide a single national consensus document for consistently and systematically implementing the project-specific QAPP requirements across the Federal agencies involved in the IDQTF (currently EPA, DoD, and DOE). In addition, implementation of the UFP-QAPP Manual will help to ensure the quality, objectivity, utility, and integrity of environmental information that the Federal government disseminates as required by EPA's Information Quality Guidelines.
