003.05(B) PROVISIONALLY CERTIFIED. A laboratory that has deficiencies but demonstrates its ability to consistently produce valid data within the acceptance limits specified in Title 179 NAC. A provisionally certified laboratory may analyze drinking water samples for compliance purposes, if its clients are notified of its downgraded status in writing, on any report. Provisional certification will not be given if the Department believes that the laboratory cannot perform an analysis within the acceptance limits specified in Title 179 NAC.
003.05(C) NOT CERTIFIED. A laboratory that possesses deficiencies and, in the opinion of the Department, cannot consistently produce valid data.
003.05(D) INTERIM CERTIFICATION. A laboratory may be granted interim certification in certain circumstances when a certified laboratory wants to add an analyte or analytes to their certification involving a method for which it already has certification and it is impossible or unnecessary to perform an on-site audit. Interim certification status may be granted if, for example, the Department determines that the laboratory has the appropriate instrumentation, is using the approved methods, has adequately trained personnel to perform the analyses, and has satisfactorily analyzed proficiency testing samples, if available, for the contaminants in question. The Department will perform an on-site audit as soon as possible but no later than three years after the application is received. The Department will review the laboratory’s quality control data and proficiency testing data before granting this type of certification.
003.05(E) RECIPROCITY. Certified by reciprocity as set out in 179 NAC 20-003.06.

03.06 CERTIFICATION BY RECIPROCITY.
