Opinion

MANGERSON, J.

¶ 1. Between October 1969 and February 1980, Certain Underwriters at Lloyd's & London Market Insurance Companies ("Lloyd's") supplied Ansul, Inc. and Tyco International (US), Inc. ("Ansul") with nine excess policies with varying coverage dates. From the 1950s to 1977, Ansul caused severe environmental damage by contaminating groundwater near the Menominee River with substantial quantities of arsenic. The Wisconsin Department of Natural Resources ("DNR") became involved in the early 1970s, and in 1981 ordered Ansul to construct a groundwater treatment system that operated until 1986, at a cost of over $11 million. In 1990, the federal Environmental Protection Agency ("EPA") determined that significant quantities of arsenic remained, and ultimately ordered Ansul to conduct further remediation.

¶ 2. Ansul did not notify Lloyd's of the contamination or government-ordered remediation until 1997, and then only by filing a declaratory action against Lloyd's in New Hampshire. Ansul later commenced similar actions in Wisconsin, which were consolidated and ultimately dismissed on summary judgment. The circuit court concluded Ansul was not entitled to coverage because it had breached the notice and cooperation clauses of the pertinent policies. We agree and affirm.

BACKGROUND

A. Contamination and Cleanup

¶ 3. Between 1957 and 1977, Ansul produced agricultural herbicides containing both organic and inorganic arsenic. From 1957 until the early 1960s, waste arsenic salt was discharged directly into the Menomi[379] nee River. Ansul also stored salt in unlined waste piles that were not covered until 1973. In 1967, Ansul transferred most of the existing waste salt, and newly produced salt, to a polyethylene-lined concrete storage vault. The vault developed cracks and the liner ruptured. By 1977, Ansul was storing approximately 95,000 tons of arsenic salt in the vault and in various other locations at its Marinette site.

¶ 4. The DNR became involved with the arsenic salt problem in 1971. In 1973, it issued consent order No. 2A-73-714 to Ansul. The DNR found the waste salt was a toxic or hazardous solid waste under Wisconsin law and required "special storage, handling, and disposal." It found that the vault, which was uncovered and exposed, was not satisfactory, as the DNR suspected that it was leaking and feared that the vault was in danger of collapse from the 37,500 tons of salt piled ten feet above its side walls. The DNR also noted that some salt had been stored outside the vault on a loading dock within ten feet of the Menominee River. In all, the DNR concluded the salt "is not being stored in a safe location in a closed container which is safe for said waste," and cited several violations of Wisconsin law. Among other things, the DNR required Ansul to study groundwater conditions and treatment and restoration technologies, establish a preliminary sampling and monitoring program, and implement a long-term plan for disposing of existing and newly generated arsenic salt.

¶ 5. Ansul representatives met with officials from the DNR and Wisconsin Attorney General's office in 1974. According to a memo from this meeting, an analysis of groundwater samples indicated "that Ansul has severely contaminated the local groundwaters with organic and inorganic arsenic, in violation of state [380] laws." A DNR official noted that although well data indicated contamination, the existence or degree of environmental damage had not yet been established. Accordingly, Ansul agreed to perform a groundwater survey, construct a groundwater model showing the rate of arsenic movement, and sample the Menominee River water, sediment, and wildlife. An October 1, 1974 memorandum from an Ansul employee recognized "contamination of ground water at the Marinette plant" and noted ongoing efforts to identify "methods which might be studied as means of removing arsenicals from the ground water." Another employee wrote, "it is just a question of time until Wis. DNR demands clean-up."

¶ 6. Discussions between the DNR and Ansul regarding cleanup intensified over the next few years. In 1976, Ansul prepared a report for the DNR describing "a suggested approach to the evaluation and possible restoration of contaminated alluvial aquifer groundwaters." The report forecasted significant capital and operating expenditures, although it qualified the projections by noting that the system's cost could not be accurately estimated without an engineering design. In 1978, the waste salt stored at the site was removed. Nonetheless, Ansul anticipated budgeting between $145,000 and $215,000 for groundwater-related expenses in 1979. Ansul's budget estimate acknowledged the possibility of long-range costs, including additional cleanup research, actual cleanup of groundwater, and disposition of contaminated river sediments, but stated that no "reasonable estimate" of those costs could be made.

¶ 7. Ansul entered into further consent orders with the DNR in 1979 and 1981. The 1981 order required Ansul to construct and operate a groundwater treatment system. The EPA notified the DNR by letter [381] that the consent order was in the best interests of the environment. The system operated from 1981 to 1986, treating 16 million gallons of groundwater and extracting 350 tons of arsenic.

¶ 8. In 1986, Ansul petitioned the DNR to discontinue groundwater extraction. Ansul provided numerous technical, economic, and environmental factors in support of this request, among them that it had spent $11 million on arsenic salt disposal and groundwater treatment since 1978. The DNR granted Ansul's petition, finding Ansul had removed a sufficient amount of groundwater and the remaining arsenic was located in the silt layer, where it would be difficult to extract. The treatment facility was decommissioned in 1986, but Ansul was required to submit a long-term groundwater monitoring plan for the abandoned salt vault.

¶ 9. By 1990, Ansul had established a $5 million reserve to deal with on-site environmental problems. That year, the EPA found that significant quantities of arsenic remained under and adjacent to Ansul's facility. Pursuant to a consent order, Ansul was required to conduct a facility investigation and a corrective measures study, and submit bi-monthly reports to the EPA and DNR. According to a 1991 internal memorandum, Ansul estimated the cost of cleanup alone at "somewhere between $8 million and $15 million."

¶ 10. After additional studies, the EPA ordered Ansul to remediate contaminated areas. Ansul estimates it has spent over $46 million on remediation, with an additional $16 to $30 million in future costs likely.
