This document provides an overview of quality management plans (QMPs) and their requirements. It discusses the key elements that must be included in a QMP, such as management and organization, quality system components, personnel qualifications and training, procurement, documentation, and more. A QMP documents an organization's quality system to ensure environmental data is of adequate quality and can be defended. The graded approach should be used to develop the QMP based on factors like the importance of work and potential decision errors.
