Getting Certified by EPA

A substantial number of our offices manage programs that certify technicians, service locations, laboratories or products.  Sometimes rather than performing the certifications ourselves, we will authorize specific independent organizations to perform these certifications.  We've created this page to help visitors find information about these programs.

Below is an automatically-generated list of EPA web pages that include “certification” in the title.  Entries are listed by when they were last updated; most recently updated pages appear at the top.
