PHMSA's drug and alcohol testing program exists to:
- Protect public safety around hazardous materials and pipeline operations
- Reduce workforce impairment risk due to substance misuse
- Ensure regulatory compliance under federal pipeline safety law
- Support employer and contractor accountability through documented testing procedures
PHMSA requires every operator and contractor with covered employees to maintain a written Anti-Drug Plan and Alcohol Misuse Prevention Plan that follows Part 199 regulations.
PHMSA drug and alcohol testing applies to:
- Pipeline operators of natural gas, hazardous liquids, carbon dioxide, and LNG facilities
- Contractors performing covered pipeline safety functions
- Covered employees identified in written testing plans
These individuals are considered safety-sensitive if they perform operations, maintenance, or emergency response functions regulated under 49 CFR Parts 192, 193, or 195.
PHMSA testing programs must include the following types of drug and alcohol tests:
- Pre-Employment Testing - Required before an employee performs a safety-sensitive role.
- Random Testing - Employees are selected unpredictably throughout the year. PHMSA has increased the minimum random drug testing rate to 50% for 2025 and 2026.
- Post-Accident Testing - Required after PHMSA reportable accidents.
- Reasonable Cause / Suspicion Testing - Conducted when supervisors observe signs of impairment.
- Return-to-Duty Testing - Required before returning to safety-sensitive work after a violation.
- Follow-Up Testing - Unannounced testing required after returning to duty under SAP guidance.
Under PHMSA regulations, DOT drug testing panels follow 49 CFR Part 40 procedures and screen for:
- Marijuana metabolites
- Cocaine metabolites
- Opiates
- Amphetamines
- Phencyclidine (PCP)
Alcohol testing under Part 199 evaluates alcohol misuse and follows procedures aligned with DOT and PHMSA guidance.
Pipeline employers must maintain:
- Written anti-drug and alcohol misuse prevention plans
- Employee education and training materials
- Proper random testing selection procedures
- Recordkeeping and reporting systems such as DAMIS entries
- Documentation of all test results and procedures
PHMSA requires operators to submit data through the Drug and Alcohol Management Information System (DAMIS), with contractor reports linked to the operator’s compliance records.
- Federal enforcement actions
