Alternative California Test Methods

This page last reviewed April 2, 2009

This file lists California test methods that have been determined by the United States Environmental Protection Agency (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, 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 file lists the regulatory agency (district or ARB), the method number, the title of the test method, and the adoption date of the method version approved by U.S. EPA, Region IX. There are comments at the end of this list associated with the test methods identified by an asterisk (*).

For further information, please contact Stanley Tong at (415) 744-1191 of U.S. EPA, Region IX.
