ATCP 93.703 Note Note: This definition is intended to assist in the understanding of these regulations and is not intended either to limit the meaning of “aggregate” in a way that conflicts with standard insurance usage or to prevent the use of other standard insurance terms in place of “aggregate.”

ATCP 93.703(4) (4) “Bodily injury” has the meaning given to this term by applicable Wisconsin statutes; however, this term does not include those liabilities that, consistent with standard insurance industry practices, are excluded from coverage in liability insurance policies for bodily injury.

ATCP 93.703 Note Note: For further information about this term, see ch. Ins 6, which interprets this term as it is used in s. 292.63 (1) (ad), Stats., for petroleum storage environmental cleanup.

However, such exclusions for property damage do not include corrective action associated with releases from tanks that are covered by the policy.
