14 Cal.App.5th 1312

Petitioner Montrose Chemical Corporation of California (Montrose) for many years manufactured the pesticide dichloro-diphenyl-trichlorethane (DDT). Real parties in interest are insurers that issued excess comprehensive general liability (CGL) policies to Montrose in relevant years. The present dispute concerns the sequence in which Montrose may access its excess CGL policies to cover its liability for environmental injuries caused by DDT.

Through a motion for summary adjudication, Montrose sought a declaratory judgment that it may "electively stack" excess policies—i.e., that it may access any excess policy issued in any policy year so long as the lower-lying policies for the same policy year have been exhausted. All of the excess insurers opposed Montrose's motion for summary adjudication; many of the excess insurers also sought through a cross-motion for summary adjudication a ruling that no insurer had a duty to pay a covered claim until Montrose had "horizontally exhausted" its lower-lying excess policies in all triggered policy years.

The trial court rejected "elective stacking" in favor of "horizontal exhaustion," ordering that higher-level excess policies could not be accessed until lower-level policies had been exhausted for all policy years. It thus denied Montrose's motion for summary adjudication and granted the excess insurers' cross-motion for summary adjudication. Montrose then filed the present petition for writ of mandate challenging the trial court's summary adjudication order.

We agree with the trial court that "elective stacking" is inconsistent with the policy language of at least some of the

222 Cal.Rptr.3d 752

more than 115 excess policies at issue and is not compelled by California Supreme Court authority. We therefore conclude that the trial court properly denied Montrose's motion for summary adjudication. Our holding is not as expansive as the trial court's, however. Specifically, we do not hold that policies must be horizontally exhausted at each coverage level and for each year before higher-level policies may be accessed. Instead, we conclude that the sequence in which policies may be accessed must be decided on a policy-by-policy basis, taking into account the relevant provisions of each policy. We therefore reverse in part the trial court's grant of the insurers' motion for summary adjudication.

FACTUAL AND PROCEDURAL HISTORY

I.

Background

From 1947 to 1982, Montrose manufactured DDT at a facility in Torrance, California. During the 1960's, conservationists began to raise concerns about the effects of DDT on the environment, and in 1972 the federal government prohibited its use within the United States. Montrose continued to manufacture DDT for export at its Torrance facility until 1982. ( Montrose Chemical Corp. v. Superior Court (1993) 6 Cal.4th 287, 292–293, 24 Cal.Rptr.2d 467, 861 P.2d 1153 ( Montrose I ).)

In 1990, the United States and the State of California sued Montrose in the United States District Court for the Central District of California under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 ( 42 U.S.C. § 9607 et seq. ) (CERCLA). (United States, et al. v. Montrose Chemical Corporation of California, et al . (U.S. Dist. Ct. C.D.Cal.), 1990, No. CV 90–3122–AAH (JRx) (CERCLA action).) The CERCLA action alleged that Montrose's operation of its Torrance facility caused environmental contamination that damaged land, water, and wildlife in the Los Angeles Harbor and neighboring waters. ( Montrose I , supra , 6 Cal.4th at pp. 292–293, 24 Cal.Rptr.2d 467, 861 P.2d 1153.)

Montrose represents that it has entered into partial consent decrees in the CERCLA action through which it has incurred damages in excess of $100 million, and that additional future damages could approach or exceed that amount.

II.

The Present Coverage Litigation

Montrose purchased "layers" of CGL policies from various insurance carriers to cover its operations at the Torrance facility from 1960 to 1986. In each of the relevant years, Montrose purchased a layer of "primary" CGL insurance policies that required the insurers to defend and indemnify Montrose for covered losses up to the policy limits. ( Montrose I , supra , 6 Cal.4th at pp. 292–293, 24 Cal.Rptr.2d 467, 861 P.2d 1153.) Above the "primary" insurance policies were multiple layers of "excess" CGL coverage, which provided additional coverage once underlying insurance was exhausted. In the early years, Montrose purchased just a few layers of excess coverage; in some later years, Montrose appears to have purchased more than 40 layers of excess coverage, with aggregate limits of

14 Cal.App.5th 1314

liability in excess of $120 million. Montrose asserts that because the policies provide for different amounts of coverage in different years, the layers of excess coverage are not uniform. To provide just a single example, in some policy years the first layer excess policies provided coverage of up to $1 million; in other years, the first layer excess policies provided coverage

222 Cal.Rptr.3d 753

of up to $2 million, $5 million, or $10 million.

In August 1990, Montrose filed the present action, Montrose Chemical Corporation of California v. Canadian Universal Insurance Co., Inc., et al. , case No. BC005158, to resolve various coverage disputes with its primary insurers....
