Pipeline Operator Drug and Alcohol Testing Reports

Department of Transportation's Drug and Alcohol Management Information System (DAMIS) collects compliance data from pipeline, LNG plant, and underground gas storage operators. The dataset is mandated by PHMSA regulations under 49 CFR Part 199. Operators with fewer than 50 covered employees report once every three years.

Use Cases

• Analyze compliance patterns across pipeline, transmission, gathering, and liquid natural gas facility types using reported operator categories.
• Identify trends in reported safety data from operators segmented by the PHMSA regulatory framework.
• Assess reporting frequency differences between operators with large workforces and those with fewer than 50 covered employees.

Strengths

• Data is mandated and submitted by regulated operators, ensuring a consistent reporting framework.
• Managed by the authoritative Department of Transportation, providing official regulatory oversight.
• Regularly updated, with a last recorded update in July 2025.

Limitations

• Data structure is unspecified, with unknown columns, rows, and sample data, complicating direct analysis.
• Available only in HTML format, which is not ideal for programmatic data extraction or quantitative analysis.
• Specific temporal coverage, geographic scope, and granular data fields are not detailed in the provided input.
