Stationary Source Audit Program; Notification of Availability and Request for Comments

The Environmental Protection Agency (EPA) is providing notification that one of the two accredited providers of audit samples for the stationary source audit program has ceased manufacturing samples. The general provisions require that the owner or operator of an affected facility required to conduct performance testing obtain audit samples if the audit samples are "commercially available" and have defined "commercially available" to mean that two or more independent accredited audit sample providers have blind audit samples available for purchase. Since there are no longer two providers, the requirement to obtain these audit samples is no longer in effect until such time as another independent accredited audit sample provider has audit samples available for purchase. The EPA is providing a 90-day comment period during which interested persons may provide comments on the suspension of the stationary source audit program and the effectiveness of the program prior to its suspension.
