Texas Hazardous and Industrial Waste Management Unit Registry

NOR Units data from the Texas Commission on Environmental Quality details waste management unit registrations across the state. It includes flags for hazardous and industrial waste classes, unit descriptions, capacity, and regulatory statuses. The dataset is maintained by the state of Texas and was last updated in April 2026.

Use Cases

• Classify waste management units by their primary waste type using Hazardous Waste Flag, Class 1 Industrial Waste Flag, and Class 2 Industrial Waste Flag columns.
• Analyze the distribution of waste management methods across Texas sites using Management Method Code 1, Code 2, and Code 3 fields.
• Track changes in unit regulatory status over time by joining on WMU Sequence Number and examining WMU Status Change Date.
• Assess the capacity and scale of registered waste units using the Capacity and Unit of Measurement for Capacity columns.

Strengths

• Contains 19 distinct columns detailing waste classification, unit status, and management methods.
• Data is directly sourced from the authoritative state environmental regulator, the Texas Commission on Environmental Quality.
• Includes temporal tracking features like WMU Status Change Date and Deed Recording Date.

Limitations

• Unknown total row count prevents assessment of dataset scale and representativeness.
• Geographic scope is limited solely to Texas, limiting broader regional analysis.
• Lack of sample data prevents verification of data quality, completeness, and potential class imbalances in flag columns.
