On March 10, 2011, the U.S. Environmental Protection Agency (EPA) issued a final rule to establish two ongoing programs that will better ensure the accuracy of calibration gases and the competency of emission stack testers. The Protocol Gas Verification Program (PGVP) and the Air Emission Testing Body (AETB) programs will strengthen our emission measurement data under the Agency’s regional emission reduction programs, such as the Acid Rain Program, the Clean Air Interstate Rule, and the proposed Transport Rule.
