Seattle Residential Heating Oil Tank Decommissioning Records

Seattle Fire Department records document permits for residential heating oil tank decommissioning under permit code 6103. The data covers permits issued since 1996, when state requirements were introduced. Records with incomplete tank information indicate missing follow-up reports from permit holders.

Use Cases

• Analyze permit issuance trends for decommissioning activities under permit code 6103 over time.
• Identify records with incomplete tank information to flag properties potentially requiring follow-up action.
• Map the geographic distribution of residential heating oil tank decommissioning permits within Seattle.

Strengths

• Data originates from the authoritative City of Seattle Fire Department permit system.
• Records provide a consistent temporal scope starting from the 1996 state requirement introduction.
• Dataset includes a specific flag (incomplete tank info) indicating missing required follow-up reports.

Limitations

• Records are incomplete for decommissioning events that occurred prior to 1996.
• The dataset is limited to residential tanks; commercial tank records require a separate public records request.
• Data quality for individual records depends on receipt of required follow-up reports from permit holders.
