Seattle Residential Heating Oil Tank Decommissioning Records

Seattle Fire Department records for permits related to decommissioning residential heating oil tanks, permit code 6103. Data includes details on tank specifications, decommissioning dates, and contractor information. SFD records begin in 1996 when the state requirement was introduced.

Use Cases

• Analyze trends in `Tank Age` and `Tank Size` at `Date Decommissioned` to model residential heating infrastructure lifecycle.
• Map decommissioning activity by `Zip Code` and `Address` for spatial analysis of environmental remediation efforts.
• Identify `Company` frequencies to assess market share among contractors performing tank decommissioning services.
• Correlate `Date Issued` with `Date Decommissioned` to study permit processing and project completion timelines.
• Classify `Fill Material` types used in decommissioning projects to evaluate common remediation methods.

Strengths

• Includes 11 specific columns such as `Tank Size`, `Tank Age`, and `Fill Material` for detailed record analysis.
• Records are maintained by the Seattle Fire Department, an official city authority.

Limitations

• Record completeness is not guaranteed; incomplete tank info indicates missing follow-up reports.
• Data coverage starts in 1996, missing any decommissioning events that occurred prior to that year.
• Dataset size, row count, and sample data are unavailable for assessing scope.
