Section 74:04:07:06 - Criteria for downgrading to provisional certification status

The secretary shall notify the laboratory in writing that it has been downgraded from certified to provisionally certified for a particular analytical parameter for any of the following reasons:

(1) Failure to analyze a performance evaluation sample within acceptance limits established by EPA, unless the laboratory has identified and corrected the problem within one month after being notified of the failure and the laboratory certification compliance officer is satisfied with the explanation of the failure. Acceptance limits established by EPA are determined through analysis of numerous samples submitted by laboratories nationwide. If the laboratory certification compliance officer determines that the laboratory need not be downgraded, he shall verify that the problem was corrected by having the laboratory analyze an unknown sample within one month. A follow-up on-site evaluation may also be performed to verify that the problem was corrected. If the laboratory fails to analyze the unknown sample within EPA acceptance limits, the laboratory shall be downgraded to provisionally certified; or

(2) Failure to notify the laboratory certification officer of major changes which might impair analytical capability.

The laboratory may remain provisionally certified for a period of six months before certification is revoked. An additional six months may be granted if the continued provisional status does not affect the generation of valid data. The laboratory must notify its clients of its downgraded status and supply a copy of the notice to the laboratory certification compliance officer.
