Pipeline Safety: Random Drug Testing Rate

Notice of minimum annual percentage rate for random drug testing.

Each year pipeline operators randomly select employees to test for prohibited drugs. The number of selections may not be less than the minimum annual percentage rate PHMSA determines, either 50 percent or 25 percent of covered employees, based on the industry's positive rate of random tests. In accordance with applicable standards, PHMSA has determined that the positive rate of random drug tests reported by operators this calendar year for testing done in calendar year 2005 is less than 1.0 percent. Therefore, in calendar year 2006, the minimum annual percentage rate for random drug testing is 25 percent of covered employees.
