The Pipeline and Hazardous Materials Safety Administration (PHMSA) has officially announced that the minimum annual random drug testing rate will remain at 50% for covered employees in the pipeline industry throughout calendar year 2026.
PHMSA’s decision stems from a review of 2024 Drug and Alcohol Management Information System (DAMIS) reports, which revealed a random drug testing positive rate greater than 1%.
Under49 CFR 199.105(c)(4), when industry-wide data shows positive rates at or above the 1% threshold, the Administrator must maintain the minimum annual random drug testing rate at 50% of all covered employees.
The regulatory framework does allow for potential rate reductions. According to49 CFR 199.105(c)(3), if the reported positive drug test rate falls below 1% for two consecutive calendar years, the Administrator may lower the random drug testing rate to 25%. However, based on the most recent DAMIS submissions, this criterion has not been met.
Why the Rate Remains at 50%
The 50% random drug testing requirement applies to operators of gas pipeline facilities, hazardous liquid pipeline facilities that transport petroleum products and other regulated materials, carbon dioxide pipeline facilities, liquefied natural gas (LNG) plants, and underground natural gas storage facilities.
Both operators and contractors performing covered functions must ensure they meet this testing threshold throughout 2026. This includes anyone performing operations, maintenance, or emergency response functions on covered pipeline facilities.
The 50% minimum random drug testing rate takes effect January 1, 2026 and remains in force through December 31, 2026.
Operators should review their current random selection rates to ensure their programs will achieve the 50% threshold across the full calendar year. Those working with aDOT consortium programshould confirm their pool management and selection processes are calibrated accordingly.
DAMIS Reporting Requirements
All operators and contractors must submit annual DAMIS reports as required by49 CFR 199.119(a). These reports provide the aggregate data PHMSA uses to calculate industry-wide positive rates and determine future testing rate adjustments.
TheDAMIS systemnow requires Multi-Factor Authentication (MFA) for all submissions. If you have not yet updated your DAMIS login credentials, you should do so before your next reporting deadline to avoid access issues.
Accurate DAMIS reporting is critical not only for your own compliance documentation but for the industry’s collective ability to potentially qualify for reduced testing rates in future years.
What This Means for Your Compliance Program
Maintaining a 50% random testing rate requires careful planning and execution. Selections must be spread throughout the calendar year, and all covered employees must have an equal chance of selection during each testing period.
For operators managing their own programs, this means tracking your covered employee count, documenting each random selection, ensuring timely test completions, and maintaining records that demonstrate compliance during audits.
Working with an experienced Consortium/Third-Party Administrator (C/TPA) can significantly reduce the administrative burden. A qualified C/TPA handles pool management, random selections, result tracking, and provides the documentation needed for PHMSA audits and DAMIS submissions.

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.

The Pipeline and Hazardous Materials Safety Administration (PHMSA) announced in the December 11, 2018 Federal Register that the random drug testing rate for 2019 will remain unchanged at 50% annually. PHMSA currently does not require random alcohol testing.

The Pipeline and Hazardous Materials Safety Administration (PHMSA) announced on December 1, 2017 a Notice of Calendar Year 2018 Minimum Annual Percentage Rate for Random Drug Testing. Effective January 1, 2018 operators of gas, hazardous liquid, and carbon dioxide pipelines and operators of liquefied natural gas facilities are required to increase the minimum annual random drug testing rate from 25% to 50% in accordance to the rules set in 49 CFR 199.105(c)(1) relating to the PHMSA minimum annual random drug testing rate.
While the minimum annual random drug testing rate was 25 percent of all covered employees for calendar year 2017, paragraph 49 CFR 199.105(c)(4) requires the Administrator to raise the minimum annual random drug testing rate from 25 percent to 50 percent of all covered employees when the data obtained from the Management Information System (MIS) reports required by § 199.119(a) indicate the positive test rate is equal to or greater than 1 percent. In calendar year 2016, the random drug test positive rate was greater than 1 percent. Therefore, the PHMSA minimum annual random drug testing rate shall be 50 percent of all covered employees for calendar year 2018.
