Agency-Specific DOT Testing
PHMSA Drug Testing Requirements
What Pipeline Workers & Urine Collectors Need to Know About 49 CFR Part 199
Quick Answer — PHMSA Drug Testing at a Glance
- ▸PHMSA authority: 49 CFR Part 199 — the Pipeline and Hazardous Materials Safety Administration's drug and alcohol testing regulation governing operators of gas pipelines, hazardous liquid pipelines, and liquefied natural gas (LNG) facilities.
- ▸Covered employees (§199.3 — "covered functions"): pipeline operations, maintenance, and emergency-response personnel — including control room operators, field technicians, welders, pipeline inspectors, and LNG facility operators.
- ▸Standard DOT 5-panel — PHMSA uses the same SAMHSA panel as FMCSA, FAA, and FTA. Unlike the FRA, PHMSA does not require an expanded 10-panel test.
- ▸PHMSA random rates (§199.105): 50% for drug testing / 25% for alcohol testing — the 25% alcohol rate is the highest random alcohol testing rate of any DOT modal agency (FMCSA, FAA, and FTA require only 10%).
- ▸Post-accident trigger (§199.105): covered accidents involving a fatality, employee hospitalization, or property damage above the regulatory threshold require mandatory drug and alcohol testing.
- ▸§40.33 is the universal collector standard — no PHMSA-specific collector certification exists. A single Cedar & Crown §40.33 certificate qualifies you to collect for PHMSA, FMCSA, FAA, FRA, and FTA — all 5 DOT agencies covered.
Buried beneath the media attention on trucking and aviation drug testing is one of the most demanding DOT testing programs in existence: PHMSA's 49 CFR Part 199, which governs drug and alcohol testing for pipeline operators across the United States. Major operators like Kinder Morgan, Williams Companies, and Enbridge — alongside hundreds of smaller regional gas utilities — are all subject to the same federally-mandated testing framework that covers everyone performing a "covered function" on a pipeline system.
For DOT-certified urine collectors, the pipeline sector represents a high-value, underserved market concentrated in specific geographic regions: Texas, Oklahoma, Louisiana, North Dakota, and West Virginia. What makes PHMSA especially significant for collectors is its random alcohol testing rate of 25% — the highest of any DOT modal agency. While FMCSA, FAA, and FTA programs require only 10% alcohol random testing, PHMSA requires 25%, meaning pipeline operators near major corridors generate significantly more frequent alcohol testing demand. This guide covers who is covered, what the rates are, how post-accident testing works, and why your§40.33 certification already qualifies you for every pipeline collection in the country.
PHMSA vs. FMCSA Drug Testing — Key Differences
Both PHMSA and FMCSA fall under the DOT umbrella and implement the same collection procedure under 49 CFR Part 40 — but their agency-specific regulations cover entirely different workforces and operate under separate CFR authorities. The most significant difference for collectors: PHMSA's 25% alcohol random rate versus FMCSA's 10%.
Employees performing "covered functions" under §199.3 — operations, maintenance, and emergency-response personnel on gas pipelines, hazardous liquid pipelines, and LNG facilities. From major interstate operators down to small municipal gas utilities.
CDL drivers operating commercial motor vehicles (CMVs) with a GVWR over 26,000 lbs, hazmat vehicles, or vehicles carrying 16+ passengers. Regulated under 49 CFR Part 382.
50% drugs / 25% alcohol — §199.105 minimum rates. The 25% alcohol rate is the highest of any DOT agency — significantly more than FMCSA's 10% alcohol rate. Pipeline operators near major corridors generate substantially more alcohol testing volume.
50% drugs / 10% alcohol — §382.305 minimum rates. Same drug rate as PHMSA, but only 10% alcohol — meaning for every 100 covered employees, FMCSA requires 10 alcohol tests while PHMSA requires 25.
49 CFR Part 199 — the Pipeline and Hazardous Materials Safety Administration's dedicated drug and alcohol testing regulation. Applies to all operators of interstate and intrastate pipeline systems carrying gas, hazardous liquids, or LNG.
49 CFR Part 382 — the FMCSA controlled substances and alcohol testing rule for CDL drivers. Compliance monitored through the Safety Measurement System (SMS) and FMCSA compliance reviews.
PHMSA Covered Function Categories — §199.3
PHMSA drug and alcohol testing under 49 CFR Part 199 applies only to employees who perform "covered functions" as defined in §199.3. The regulation is function-specific — not all pipeline company employees are covered, only those whose duties involve direct operations, maintenance, or emergency response on the pipeline system. If an employee performs even one covered function, they are subject to the full Part 199 testing program.
Pipeline Operations
Employees who operate gas, hazardous liquid, or LNG pipeline systems — including valve operators, pipeline controllers, and personnel who manage the flow of product through pipeline infrastructure. Operations personnel make real-time decisions that directly affect system safety.
§199.3 — Covered FunctionPipeline Maintenance
Employees who perform maintenance on pipeline systems and equipment — including field technicians, corrosion control specialists, pipeline welders, and maintenance crews who inspect, repair, or service pipeline infrastructure. Welding errors on high-pressure pipeline systems can have catastrophic consequences.
§199.3 — Covered FunctionEmergency Response
Employees who perform emergency-response functions on pipeline systems — personnel who respond to pipeline ruptures, gas leaks, hazardous liquid spills, or LNG incidents. Emergency responders must make rapid, accurate decisions under extreme conditions where impairment is a direct public safety risk.
§199.3 — Covered FunctionLNG Facility Operations
Employees who operate liquefied natural gas (LNG) facilities — including LNG storage operators, transfer personnel, and facility controllers. LNG facilities handle cryogenic materials at extremely high energy density; impairment in these environments creates catastrophic explosion and fire risk.
§199.3 — Covered FunctionControl Room Operations
Pipeline control room operators who monitor and direct pipeline operations remotely — using SCADA systems and pipeline monitoring tools to manage large-scale transmission networks. Control room operators make continuous decisions affecting hundreds of miles of pipeline infrastructure.
§199.3 — Covered FunctionPHMSA Random Testing Rates — §199.105
Under §199.105, PHMSA-regulated pipeline operators must conduct random drug testing at a minimum annual rate of 50% of covered employees — identical to FMCSA and FTA. But PHMSA's random alcohol testing rate of 25% is the highest of any DOT modal agency. FMCSA, FAA, and FTA all set their alcohol random rate at 10%; PHMSA requires 2.5× that rate. For a pipeline operator with 100 covered employees, this means 25 alcohol tests per year versus 10 for comparable FMCSA or FTA programs.
This elevated alcohol rate is not an accident — pipeline operations involve high-pressure systems carrying flammable or toxic materials where impaired judgment can trigger explosions, fires, and environmental disasters affecting entire communities. The PHMSA rate reflects the severity of consequences from impairment in pipeline environments compared to most other transportation sectors.
PHMSA Post-Accident Testing — §199.105
Post-accident testing under the PHMSA program is triggered by the severity of the pipeline incident. Under §199.105, covered accidents involving a fatality, employee hospitalization, or property damage above the regulatory threshold require mandatory drug and alcohol testing. Unlike FMCSA's vehicle-citation trigger or FTA's supervisor-discretion framework, PHMSA's post-accident triggers center on injury severity and damage magnitude.
§199.105 Post-Accident Trigger Thresholds
Fatality
Any covered accident resulting in a human fatality triggers mandatory post-accident drug and alcohol testing for all covered employees whose performance could have contributed to the accident. No supervisory discretion — testing must occur.
Hospitalization
A covered accident that results in an employee or member of the public being admitted to a hospital for inpatient care triggers mandatory post-accident testing. Outpatient emergency treatment that does not result in inpatient admission may not meet this threshold — the inpatient admission requirement is the key criterion.
Property Damage
Property damage above the regulatory threshold set by PHMSA triggers mandatory post-accident testing. The applicable threshold amount is established in Part 199 and subject to periodic regulatory adjustment. Operators must know the current threshold for their pipeline system type.
Collection Windows
Alcohol collection must be attempted within 2 hours of the accident. If not completed within 2 hours, the operator must document why and continue attempting for up to 8 hours. After 8 hours, all attempts must cease and the failure to test must be documented in the operator's records.
Drug specimen collection must be completed within 32 hours of the accident. After 32 hours, the operator must document the reason and cease further attempts — the drug test cannot be conducted after this window closes.
Pipeline Post-Accident Windows Are Unforgiving — Use a Qualified Collector
A pipeline incident triggers a 2-hour alcohol window and a 32-hour drug window. In remote pipeline locations — rural Texas, the North Dakota Bakken, West Virginia mountain terrain — the distance to the nearest collection site can make or break the testing window. A specimen collected by a non-§40.33-qualified collector may be deemed invalid, exposing the pipeline operator to PHMSA enforcement action. Operators in remote corridors who have pre-identified a qualified mobile collector can meet these windows; those who haven't often cannot.
PHMSA 5-Panel Drug Test — Substances & Cutoff Levels
PHMSA uses the standard DOT 5-panel drug test defined in 49 CFR Part 40 (§40.85) — the same panel used by FMCSA, FAA, and FTA. Unlike the FRA, which requires a 10-panel expanded test for railroad workers under FRA drug testing requirements, PHMSA does not expand beyond the five standard DOT substances. The collection procedure is identical: urine specimen, Federal Custody and Control Form (CCF), and §40.91 specimen integrity checks.
Initial cutoffs are per §40.85; confirmation (GC/MS) cutoffs are per §40.87.
| Substance | Initial Cutoff (§40.85) | Confirmation Cutoff (§40.87) | Pipeline Relevance |
|---|---|---|---|
| Marijuana (THC) | 50 ng/mL | 15 ng/mL | Impairs judgment, reaction time, and spatial awareness — high risk for control room operators, field technicians, and LNG facility personnel managing complex, high-pressure systems. |
| Cocaine | 150 ng/mL | 100 ng/mL | Creates overconfidence and impairs decision-making in high-stakes environments — dangerous for pipeline operations where misjudgments can trigger explosions or environmental releases. |
| Amphetamines / Methamphetamines | 500 ng/mL | 250 ng/mL | Stimulants that distort risk assessment and promote erratic behavior — incompatible with the precise, methodical safety protocols required in pipeline maintenance and emergency response. |
| Opioids (Heroin / Morphine / Codeine) | 2,000 ng/mL | 2,000 ng/mL | Sedation and cognitive impairment in pipeline environments — operators, welders, and emergency responders working with high-pressure systems and hazardous materials cannot safely perform covered functions under opioid impairment. |
| Phencyclidine (PCP) | 25 ng/mL | 25 ng/mL | Causes severe perceptual distortion and unpredictable behavior — extreme risk in any pipeline covered function where impaired judgment could trigger catastrophic infrastructure failure. |
PHMSA uses the same standard DOT 5-panel as FMCSA, FAA, and FTA — not the 10-panel expanded test required by FRA for railroad workers. See FAA drug testing requirements and FTA drug testing requirements for cross-agency comparisons.

Get Certified for $99§40.33 Is the Collector Standard — No PHMSA-Specific Cert Exists
Although PHMSA drug testing is governed by 49 CFR Part 199, the actual urine collection procedure is controlled by 49 CFR Part 40 — the universal DOT collection regulation that applies identically across all five DOT agencies. This means:
- ✓The same Federal Custody and Control Form (CCF) is used for every PHMSA pipeline collection
- ✓The same §40.91 specimen integrity checks (temperature range, color, clarity) apply
- ✓The same §40.33 collector qualification and training requirements are mandatory
- ✓The same chain-of-custody procedures govern every specimen from collection to SAMHSA-certified lab
A Collector Certified for Trucking Is Already Qualified for Pipeline Testing
There is no "PHMSA-specific" collector certification — §40.33 is the universal DOT collector standard across all agencies. A Cedar & Crown-certified collector who conducts FMCSA-covered CDL driver collections is already fully qualified to serve pipeline operators under Part 199: major interstate operators like Kinder Morgan, Williams Companies, and Enbridge, regional hazardous liquid pipeline companies, natural gas gathering and transmission systems, and small municipal gas utilities. Every Part 199-covered operator must use a §40.33-qualified collector for all required tests — including their higher-frequency 25% alcohol random program. See DOT collector job opportunities for how to get on pipeline operator testing rosters.
Pipeline Corridors: Where PHMSA Collector Demand Concentrates
PHMSA-regulated pipeline operators are geographically concentrated along the United States' major natural gas transmission, hazardous liquid, and LNG infrastructure corridors. Collectors near these regions encounter a distinct and consistent source of Part 199 testing demand — separate from the trucking and transit programs that dominate most urban markets.
Texas
The largest pipeline state in the U.S. — home to Permian Basin oil and gas gathering systems, Gulf Coast hazardous liquid transmission lines, LNG export facilities, and major interstate gas pipeline infrastructure. Major operators include Kinder Morgan, Enterprise Products Partners, and Boardwalk Pipeline.
Oklahoma
A major natural gas gathering and processing hub — with significant pipeline infrastructure connecting Midcontinent production to Gulf Coast markets. ONEOK and Enable Midstream (now Enable Gas Transmission) are major Part 199-covered operators in the state.
Louisiana
Gulf Coast terminus for multiple major interstate pipeline systems, and home to LNG export facilities and hazardous liquid terminals. Louisiana sits at the nexus of several major pipeline corridors, creating dense demand for Part 199-qualified collectors.
North Dakota
Bakken Formation oil production has created extensive hazardous liquid gathering and transmission infrastructure — with major growth in both crude oil pipelines and NGL systems. A historically underserved market for qualified DOT collectors relative to its pipeline density.
West Virginia
Marcellus and Utica Shale natural gas gathering, processing, and transmission systems — with significant pipeline density relative to population. Equitrans Midstream and EQT Corporation operate major systems in the state. Rural geography creates demand for mobile collectors who can reach remote pipeline facilities.
