The purpose and effect of the proposed rule is to expand the current random drug testing program to include other specified positions in addition to certified officers, provide a review process for employees whose positions have been designated as subject to random testing, provide for on-site presumptive testing with a confirmation process follow-up for presumptive positive results, clarify situations that will be considered to be a failed drug test, permit employees who are not in test-designated positions, but volunteer for testing to withdraw from volunteer status prior to testing, and include specific consequences for positive test results.
