This Web site provides guidance for demonstrating the effectiveness of innovative and/or alternative sewage sludge disinfection processes for the purposes of receiving a recommendation of equivalency to a process that significantly or further reduces pathogens. Biosolids are sewage sludges that have been treated and managed to meet state and federal standards. 40 CFR Part 503 regulates sewage sludge use and disposal.

A new process to significantly or further reduce pathogens can only be granted equivalency by the permitting authority. The Pathogen Equivalency Committee (PEC) advises permitting authorities on equivalency recommendations.
