## Abstract

EPA is taking final action to promulgate amendments to the General Provisions to allow accredited providers to supply stationary source audit samples and to require sources to obtain and use these samples from the accredited providers instead of from EPA, as is the current practice. All requirements pertaining to the audit samples have been moved to the General Provisions and have been removed from the test methods because the current language in the test methods regarding audit samples is inconsistent from method to method. Therefore, deleting all references to audit samples in the test methods eliminates any possible confusion and inconsistencies. Under this final rule, the requirement to use an audit sample during a compliance test will apply to all test methods for which a commercially available audit exists.
