Pathogen Equivalency Committee


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.

Created by EPA in 1985, the Pathogen Equivalency Committee (PEC) is a federally sponsored technical group that provides technical assistance and recommendations on process equivalencies for pathogen reduction in sewage sludge to government and industry. This website provides guidance from the PEC 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.

Information for potential PEC applicants: Before applying to the PEC for equivalency, please read the information below and get acquainted with the process.

In reviewing equivalency applications, the PEC ensures that new or alternative processes proposed for sewage sludge treatment are robust and effectively reduce pathogens. The PEC reviews and makes recommendations to relevant federal and/or state permitting authorities on the merits of these applications and determines if they are equivalent to the processes currently listed in the 40 CFR Part 503, Subpart D, regulation.

A quality assurance project plan (QAPP) should be developed before beginning testing so that the desired quality in sample collection, laboratory analysis, data validation and reporting, as well as documentation and record keeping is achieved and maintained.

You may read about examples of companies and products that have received equivalency related to processes to significantly reduce pathogens and processes to further reduce pathogens.
