The document provides the technical background and justification for the U.S. Environmental Protection Agency's (EPA's) proposed regulation (40 CFR Part 503) covering the disposal of municipal sewage sludge in sludge-only landfills (monofills). The document summarizes current practices at monofills and presents the risk assessment methodology used to derive human health and environmental risk-based limits for contaminants in monofilled sewage sludge. The underlying assumptions of the risk assessment methodology, embodied in a series of computer models, are discussed, the values assigned to the model parameters are presented and justified, and the risk-based contaminant limits derived by the models are presented. The various siting limitations and management practices mandated by the regulation are discussed and justified.
