  • Carry out that sampling plan and
  • Complete and submit an official pathogen reduction equivalency application package.

The Pathogen Equivalency Committee will then evaluate the package and make its recommendation through the appropriate channels. This typical equivalency recommendation process is shown in the flow diagram (PDF) (1 pg, 309K).

The Equivalency Recommendation Process. 1) Initiation Phase: Contact Permitting Authority; Contact PEC. 2) Quality Assurance Project Plan (QAPP) Phase: Prepare QAPP; PEC Reviews QAPP; Implement QAPP. 3) Application Phase: Prepare Application; PEC Reviews; Prepare O&M Manual 4) Notification Phase: PEC Issues recommendation to the Office of Science and Technology (OST); OST Reviews; OST Forwards Recommendation to Permitting Authority. Finally, the Permitting Authority may issue Formal Equivalency.
