Dear Mr. Lem: I am pleased to advise you the Texas Commission on is renewing your laboratory's accreditation. The accreditation is valid until the expiration date on the certificate and scope, contingent on continued compliance with the standards for accreditation and requirements of the state of Texas. We are also continuing secondary accreditation based on your application and primary NELAP accreditation from the states of Oregon and New York according to the attached Fields of Accreditation. Your laboratory's secondary accreditation is valid until the expiration date on the certificate and scope, contingent on continued compliance with the requirements of the state of Texas as well as those of your primary Accreditation Bodies. I am enclosing an accreditation certificate and listing of the fields of accreditation. Please review the enclosures for accuracy and completeness. In the meantime, please contact me by telephone at (512) or electronic-mail at frank.jamison@tceq.texas.gov if I can provide any additional information or assistance.
