2025 PHMSA Random Drug Testing Rate Published

2025 PHMSA Random Drug Testing Rate

The Pipeline and Hazardous Materials Safety Administration (PHMSA) published that they are raising the minimum annual random drug testing rate for 2025 to 50% annually, up from 25% annually.  The PHMSA published the new random drug testing rate for 2025 in the November 20, 2024 Federal Register.

The PHMSA can adjust the minimum random drug testing rate annually based on the reported positive rate of the industry’s random drug tests.  In accordance with 49 CFR Part 199.105(c)(3) if the reported positive random drug testing rate is below one (1) percent for two consecutive years, the PHMSA may lower the random drug testing rate to 25% for all covered employees.  49 CFR Part 199.105(c)(4) requires the PHMSA to raise the minimum random drug testing rate from 25% to 50% for all covered employees when the latest reported positive random drug testing rate is equal or greater than one (1) percent.  The reported positive random drug testing percent for CY 2023 was greater than one percent, requiring the PHMSA to raise the annual random drug testing rate for CY 2025 to 50% for all covered employees.
