The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration announced December 8, 2017 that during calendar year 2018, the minimum random drug testing rate will be increased to 50%.

Operators of gas, hazardous liquid, and carbon dioxide pipelines and operators of liquefied natural gas facilities must randomly select and test a percentage of all covered employees for prohibited drug use. The minimum annual random drug testing rate was 25% of all covered employees for calendar year 2017. However, the PHMSA regulations require the Administrator to raise the minimum annual random drug testing rate from 25% to 50% of all covered employees when the data obtained from the Management Information System reports (required to be filed by covered entities under PHMSA regulations) indicate the positive test rate is equal to or greater than 1%. In calendar year 2016, the random drug test positive test rate was greater than 1%. Therefore, the PHMSA minimum annual random drug testing rate shall be 50% of all covered employees for calendar year 2018.
