WAC 246-390-040   Provisional certification.  Laboratories which have deficiencies requiring corrective action but which can produce valid analytical data as determined by the CO may be given provisional certification. The department may downgrade a laboratory to provisional certification for failure to:

     (1) Analyze a PE sample and/or an intercomparison sample, or any other unknown test sample within the acceptance limits established by the EPA and/or the department. Failure on a mandatory PE sample is defined as a failure on any concentration provided, unless otherwise specified by the EPA and/or the department. The laboratory shall be given an opportunity to request a make up PE or QC sample before the CO takes action.

     (2) Notify the CO in writing within thirty days of major change impairing analytical capability, such as personnel, equipment, or location.

     (3) Demonstrate that the laboratory maintains the required standard of quality, based upon an on-site evaluation. See certification manual for minimum standard of quality requirements.

     (4) Promptly send reports of analysis to the department as described in the certification manual.

     (5) Promptly notify the public water system by the end of the business day, or the department if the public water system can not be notified, of results exceeding MCL or SAL. For all results exceeding MCL or SAL the laboratory must notify the department as soon as possible.
