Ariz. Admin. Code § R18-12-303 - Amount and Scope of Required Financial Responsibility

A. Owners and operators of petroleum USTs shall demonstrate financial responsibility for taking corrective action and for compensating 3rd parties for bodily injury and property damage caused by accidental releases arising from the operation of petroleum USTs in at least the following per-occurrence amounts:

1. For owners and operators of petroleum USTs that are located at petroleum marketing facilities, or that handle an average of more than 10,000 gallons of petroleum per month based on annual throughput for the previous calendar year: $1 million;

2. For owners and operators of petroleum USTs not described in subsection (A)(1): $500,000.

B. Owners and operators of petroleum USTs shall demonstrate financial responsibility for taking corrective action and for compensating 3rd parties for bodily injury and property damage caused by accidental releases arising from the operation of a petroleum UST in at least the following annual aggregate amounts:

1. For owners and operators of 1 to 100 petroleum USTs: $l million,

2. For owners and operators of 101 or more petroleum USTs: $2 million.

C. For the purposes of subsections (B) and (G) only, "a petroleum underground storage tank" means a single containment unit and does not mean combinations of single containment units.

D. Except as provided in subsection (E), if owners and operators use separate mechanisms or combinations of separate mechanisms to demonstrate financial responsibility for taking corrective action, compensating 3rd parties for bodily injury and property damage caused by sudden accidental releases, or compensating 3rd parties for bodily injury and property damage caused by nonsudden accidental releases, the amount of assurance provided by each mechanism or combination of mechanisms shall be in the full amount specified in subsections (A) and (B).

E. If owners and operators use separate mechanisms or combinations of separate mechanisms to demonstrate financial responsibility for different petroleum USTs, the annual aggregate required shall be based on the number of tanks covered by each such separate mechanism or combination of mechanisms.

F. If owners and operators utilize one mechanism, separate mechanisms, or combinations of separate mechanisms to demonstrate financial responsibility for petroleum USTs in more than one state or territory, with more than one implementing agency, the identification of systems covered by each mechanism shall include the implementing agency for each facility or group of facilities. All facilities subject to the requirements of this rule shall also be identified by the UST facility identification number assigned by the Department.

G. Owners and operators shall review the amount of aggregate assurance provided whenever additional petroleum USTs are acquired or installed. If the number of petroleum underground storage tanks for which assurance shall be provided exceeds 100, owners and operators shall demonstrate financial responsibility in the amount of at least $2 million of annual aggregate assurance by the anniversary of the date on which the mechanism demonstrating financial responsibility became effective. If assurance is being demonstrated by a combination of mechanisms, owners and operators shall demonstrate financial responsibility in the amount of at least $2 million of annual aggregate assurance by the 1st-occurring effective date anniversary of any one of the mechanisms combined, other than a financial test or guarantee, to provide assurance.

H. The amounts of assurance required under this Section exclude legal defense costs.

I. The per-occurrence and annual aggregate coverage amounts required by this Section do not limit the liability of owners and operators.
