Return-to-Duty After a Random Positive Test

Dana Ruiz, a certified conductor with eight years of service, was selected for a random drug test on February 3. The laboratory reported a marijuana metabolite level above the cutoff; the medical review officer confirmed the result. Ruiz was removed from service and her conductor certificate was revoked. She completed a substance abuse professional evaluation, followed the recommended education and treatment, and tested negative on a return-to-duty test two weeks ago. Her follow-up testing plan calls for six tests in the first 12 months. On June 15 her supervisor wants to reissue the certificate immediately so she can protect her seniority, saying 'the SAP and the negative test close the case.' Ruiz has not yet been observed in the field since her removal.

1. Does return-to-duty compliance automatically entitle Ruiz to a new certificate?

Read the worked answer

No. Part 219 return-to-duty requirements are necessary but not sufficient. Part 242 certification is a separate eligibility determination. The railroad must evaluate whether Ruiz meets the certification standards after the positive test and revocation, including the SAP evaluation, the negative return-to-duty test, and the follow-up plan. It must also follow its FRA-approved program and any waiting period or conditions. The supervisor's statement confuses medical clearance with certification. Reissuing without a documented determination would leave the certificate unsupported and could expose the railroad to enforcement.

2. What procedural steps are required before reissuing the certificate?

Read the worked answer

The railroad must give Ruiz written notice of the revocation and its basis and provide the dispute resolution process, including review board, petition, hearing, and appeal, if she contests it. Before recertification, it should document the SAP evaluation, the negative return-to-duty test, the follow-up testing schedule, and a reasoned fitness determination. The railroad should not put her back in service until the certificate is actually issued. If the railroad treats the original revocation as final, it must still make a new certification decision; it cannot simply reactivate the old certificate as though nothing happened.

3. What post-return monitoring applies after she returns to service?

Read the worked answer

Follow-up testing under Part 219 continues, here six tests in the first 12 months, and the railroad must also monitor operational performance under Part 242, including the required observation and efficiency testing. Ruiz should be observed in the field before or soon after return, and the observation must be documented. Follow-up testing is not a substitute for performance monitoring, and performance monitoring is not a substitute for the testing plan. The railroad should retain both sets of records and ensure that supervisors know she is subject to follow-up testing.
