What are Clearinghouse queries?

Beginning January 6, 2020, employers subject to the Clearinghouse final rule will be required to take certain actions in the Clearinghouse, such as querying the Clearinghouse for information on current and prospective employees to verify they are not prohibited from performing safety-sensitive functions due to an unresolved drug and alcohol program violation. Employers will be required to query the Clearinghouse as part of every pre-employment driver investigation, and at least annually for drivers they employ. All queries require driver consent.

Why does an employer need to purchase a query plan?

Employers will be charged a fee for conducting queries in the Clearinghouse. If an employer works with a consortium/third-party administrator (C/TPA), they must purchase a query plan before the C/TPA can conduct queries in the Clearinghouse on their behalf. C/TPAs cannot purchase a query plan on behalf of an employer.

DOT Publishes Drug Testing Rule

Today, April 23, 2019, the Department of Transportation (DOT) published a final rule that makes minor technical corrections to the OST, FAA, FTA, and PHMSA regulations governing drug testing for safety-sensitive employees to ensure consistency with the recent amendments made to the Department of Transportation’s regulation, “Procedures for Transportation Workplace Drug and Alcohol Testing Programs,” which added requirements to test for oxycodone, oxymorphone, hydrocodone, and hydromorphone to DOT-regulated drug testing programs. The changes to the Department’s regulation make it necessary to refer to these substances, as well as the previously covered drugs morphine, 6-acetylmorphine, and codeine, by the more inclusive term “opioids,” rather than “opiates.” This rule amends the term in the FAA, FTA, and PHMSA regulations to ensure that all DOT drug testing rules are consistent with one another and with the Mandatory Guidelines for Federal Workplace Drug Testing Programs. In addition, this rule makes a conforming amendment to include the term “opioids” in the wording of the Department’s annual information collection requirement and clarifications to section 40.26 and Appendix H regarding the requirement for employers to follow the Department’s instructions for the annual information collection.
