## Abstract

This action amends EPA's Method 301, Field Validation of Pollutant Measurement Methods from Various Waste Media. We revised the procedures in Method 301 based on our experience in applying the method and to correct errors that were brought to our attention. The revised Method 301 is more flexible, less expensive, and easier to use. This action finalizes amendments to Method 301 after considering comments received on the proposed rule published in the Federal Register on December 22, 2004.
