Approved Alternative Monitoring and Test Methods

This page last reviewed April 14, 2010

This file lists U.S. EPA alternative monitoring methods and California test methods that have been determined by the U.S. EPA, Region IX, to be technically acceptable for inclusion into the State Implementation Plan (SIP) or for use in conjunction with SIP approved rules. However, the U.S. EPA reserves the right to determine the appropriateness of any accepted test method for compliance determinations in new or revised rules submitted for incorporation into the SIP. Initial compliance testing for NSPS must be done with U.S. EPA methods.

The links to the following web sites are provided for information only. Although newer versions of some methods may be available at these web sites, only the versions specially approved by EPA can be used to demonstrate compliance with SIP rules.
