The San Francisco Municipal Transportation Agency (SFMTA) has determined that Class 7408 Assistant Power System Operator is a “safety-sensitive” position, under regulations issued by the Federal Transit Administration (49 CFR Part 655). Federal law requires that all transit employees who perform safety-sensitive functions be subject to random, post-accident, reasonable suspicion, return-to-duty and follow-up drug and alcohol testing. All applicants for Safety-Sensitive positions shall undergo urine drug testing prior to employment and within 90 days prior to performing Safety-Sensitive functions for the first time. Receipt by the SFMTA of a negative test result is required prior to the employee being placed on the payroll. A positive, adulterated, negative dilute or substituted test will result in a decision not to hire, and the applicant’s name will be removed from the list of eligibles for Safety-Sensitive positions. The SFMTA will not consider hiring any person who tested positive, adulterated, substituted or refused to submit to testing for a minimum of two years following the positive test.

In addition, each applicant who has worked for a Department of Transportation (DOT) – regulated employer(s) within the last two years will be required to sign a consent form, prior to appointment, authorizing SFMTA to obtain information from their prior employers concerning their drug and alcohol test history. Each applicant will also be required to provide SFMTA with information regarding whether, during the last two years, the applicant tested positive or refused to test on any pre-employment drug or alcohol test administered by an employer to which the applicant applied for, but did not obtain, safety-sensitive transportation work covered by DOT drug and alcohol testing rules. SFMTA will not hire any applicant for a safety-sensitive position who fails to provide this information or fails to provide written consent for the release of information from prior employers.
