Virginia aboveground oil tank requirements

Virginia DEQ registration: individual and aggregate tests

Virginia's Part II AST registration provisions generally apply to an individual oil AST with capacity greater than 660 gallons, or a facility with aggregate nonexcluded aboveground oil storage greater than 1,320 gallons. These thresholds are not general-purpose fire permits and are distinct from federal SPCC requirements.

Other state oil-storage obligations can have different triggers

Virginia Part III pollution-prevention provisions and Part IV oil-discharge contingency planning generally use 25,000 gallons or greater for a qualifying individual AST or facility aggregate, subject to specific exclusions. Confirm which part applies; a registration threshold is not a blanket engineering or spill-planning threshold.

Check exclusions before making a compliance decision

Among the specific exclusions in 9VAC25-91-30 are ASTs of 660 gallons or less; tanks integral to machinery and used solely by it; and certain noncommercial farm or residential motor-fuel ASTs of 1,100 gallons or less. Some requirements also exclude certain qualifying onsite heating-oil storage. These exceptions are precise and do not excuse unrelated fire, local, or federal obligations.

Registration timing and local coordination

9VAC25-91-100 addresses registration after use or ownership transfer, with a 30-day window for qualifying facilities and renewal every five years or on transfer, whichever comes first. Verify your factual situation, DEQ forms, and local emergency-services notification before setting a project schedule.

Fire-code review is separate

Virginia's Statewide Fire Prevention Code incorporates the 2021 International Fire Code with state amendments. Its administrative and permitting provisions differ from the unamended model code; IFC appendices are not automatically statewide rules. Confirm installation, operational permitting, dispensing, setbacks, venting, access and inspection requirements with the local fire/building authorities.

Financial responsibility: another separate threshold

Under 9VAC25-640-20, operators of qualifying Virginia oil AST facilities with maximum storage capacity of 25,000 gallons or greater must demonstrate financial responsibility unless a stated exemption or exclusion applies. 9VAC25-640-30 lists exclusions. Under 9VAC25-640-50, the required coverage for containment and cleanup is generally calculated at five cents per gallon of an operator's total qualifying Virginia aboveground capacity, capped at $1 million. Approved financial mechanisms vary; this does not automatically mean an insurance policy is required. Confirm agency treatment of the specific facility.

Project buyer checklist

• Record location, oil type, tank purpose and individual/aggregate capacities.
• Determine whether any precise environmental exclusions apply.
• Check current DEQ registration, notification and renewal requirements.
• Ask the local fire and building authority for the required site plan, equipment and permit review.
• Assess federal SPCC separately under EPA rules.
• Confirm delivery access, filling, dispensing, containment and emergency arrangements before purchase.
