In-State Laboratories

An on-site laboratory evaluation will be scheduled for your laboratory approximately two to three months prior to the expiration date on your certificate. You will receive notification of this evaluation by mail. To enable the Office of Environmental Laboratory Certification to perform the evaluation more efficiently, the following items should be available for review on the day of the scheduled evaluation.

• In-State Laboratory Evaluation Documentation Required for Renewal

If you have any questions concerning the evaluation contact us via email or contact the Laboratory Certification Officer (LCO) scheduled to perform your evaluation.

Out-of-State Laboratories

An out-of-state laboratory's certificate reflects the expiration date of its certifying authority. Forty-five (45) days prior to expiration, our office sends a letter to the out-of-state laboratory with a checklist of required items that must be submitted for renewal of its certification. If this required documentation is not submitted by the date of expiration, a letter is sent to the laboratory on the date of expiration notifying it of decertification actions. A copy of the required documentation for renewal of certification appears below:
