MEMORANDUM OPINION
Ex-Cеll-O Corporation (“Ex-Cell-O”), its subsidiary McCord Gasket Corporation (“McCord”), and McCord’s subsidiary Davidson Rubber Company (“Davidson”) (“policyholders”) move for partial summary judgment declaring the duty of Fireman’s Fund Insurance Companies (“Fireman’s Fund”), Wausau Insurance Companies (“Wausau”), and Zurich Insurance Company (“Zurich”) (“primary insurers” or “insurers”) 1 to defend the policyholders against potential liability for allegedly contributing to environmental contamination at twenty-two locations. I have jurisdiction pursuant to 28 U.S.C. § 1332.
Each site requires clean-up of environmental damage. The critical question is who will pay for the work. Congress addressed the question in the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”), 42 U.S.C. §§ 9601-9657, which authorizes administrative and judicial proceedings to effect clean-up of contaminated sites and to compel contributions to the cost of clean-up by owners and operators of the sites, and by generatоrs of materials dumped at the sites. Some states have enacted similar legislation.
*74 At least one government agency has taken or is contemplating action pursuant to these statutes at each site. The policyholdеrs have received written notice, familiarly known as a “PRP letter,” from a government agency that considers them potentially responsible for contamination at sixteen sites. 2 From the owner or operator of four other sitеs, the policyholders have received written notice that an agency has taken action, and that the owner or operator considers the policyholders potentially responsible. 3 The policyholders exрect imminent agency action at one site. 4 Finally, for one site, the policyholders are third-party defendants in a federal court action. 5
The policyholders seek a defense at each site. The insurers deny covеrage. The insurers on the risk during the time the policyholders allegedly used each site are:

Asterisked sites involve alleged dumping by McCord or Davidson prior to Ex-Cell-O’s purchase of the companies in 1978. Ex-Cell-0 contends that its own insurance рolicies, as well as the policies issued separately to McCord and Davidson, cover these sites, but it does not test this claim on its motion for partial summary judgment. Accordingly, the asterisked sites identify only the separate insurer for McCord or Davidson.
The policyholders purchased comprehensive general liability policies that define the insurers’ duty to defend broadly. Fireman’s Fund and Wausau use identical language:
[T]he Company shall have the right and duty to defend any such suit against the insured seeking damages on account of such bodily injury or property damage, even if any of the allegations of the suit are groundless, false or fraudulent, and may make such an investigation and settlement of any claim or suit as it deems expedient....
The Zurich policy is only slightly different:
[T]he company shall ... defend any such suit against the insured alleging such injury, sickness, disease or destruction and seeking damages on account thereof, even if such suit is groundless, false or fraudulent; but the compаny may make such investigation, negotiation and settlement of any claim or suit as it deems expedient....
The language obligates the insurers to defend any claim against the policyholders
es that the policyholders received а PRP letter for this site, and the policyholders’ answer admits the allegation. First Amended Complaint at If 47; Policyholders' Answer to First Amended Complaint at ¶ 31 (admitting ¶ 47 of the First Amended Complaint).

“so long as the allegations against the insured
even arguably
come within the policy coverage.”
The Detroit Edison Company v. Michigan Mutual Insurance Company,
The insurеrs claim they have no duty to defend the environmental claims until the policyholders become defendants in a traditional lawsuit for money damages. The insurers construe their policies too narrowly: coverage does not hingе on the form of action taken or the nature of relief sought, but on an actual or threatened use of legal process to coerce payment or conduct by a policyholder. In
United States Aviex Company v. Travelers Insurance Company,
It is merely fortuitous ... that the state has chosen to have plaintiff remedy the contaminаtion problem, rather than choosing to incur the costs of clean-up itself and then suing plaintiff to recover those costs.
United States Aviex,
The insurers also argue that the exclusion for damages to property owned by the policyholders precludes coverage.
6
I hold that the exclusion does not preclude coverage because the claims at sites owned by the policyholders include property damage to adjoining landowners and to the public.
See United States Aviex,
Wausau and Fireman’s Fund also deny coverage because оf a pollution exclusion contained in some of their policies: 7
This insurance does not apply ... to bodily injury or property damage arising out of the discharge, dispersal, release or escape of smoke, vaрors, soot, fumes, acids, alkalis, toxic chemicals, liquids or gases, waste materials or other irritants, contaminants or pollutants into or upon the land, the atmosphere or any water course or body of water; but this exclusion doеs not apply if such discharge, dispersal, release or escape is sudden and accidental....
Application of the pollution exclusion depends exclusively upon the process by which pollutants entered the еnvironment.
See Jonesville Products, Inc. v. Transamerica Insurance Group,
We find that the circuit court [in holding that the insurer had no duty to defend] failed to distinguish between the frequency of acts which resulted in the release of contaminants and plaintiff’s [insured’s] knowledge or notice of the release of pollutants as a result of those acts. The ... [underlying complaint] did not specify ... how the toxic wastes entered the ground. There may have bеen either intentional dumping or burial, unintentional spills or leaks from inadequate containers, or other accidents. The allegations ... are couched in general terms and encompass unintentional release into the grоund.
The circuit court erred in finding that the allegation of “continuous” negligent discharge of waste ... took [the underlying complaint] ... out of defendant’s [insurer’s] exception for “sudden and accidental” release. It is possible that the relеases could have been sudden, i.e., unexpected, and accidental, i.e., unintended, and thus outside the exclusion.
Jonesville,
Application of this standard requires additional facts. Fireman’s Fund and Wausau may not rely on the pollution exclusion to deny a defense until they are able to establish on a motion for summary judgment or at trial that the release of pollutants was expected or intended.
See Jonesville,
Finally, the parties dispute the appropriate trigger of coverage. The policies cover occurrences within the pоlicy period. I hold that each exposure of the environment to a pollutant constitutes an occurrence and triggers coverage.
See Continental Insurance,
The policyholders allegedly exposed the sites to pollutants during the periods recorded earlier in this opinion. An insurer on the risk during the periоd of alleged exposure is liable for the policyholders’ defense in the proportion that the period it was on the risk bears to the total period of alleged exposure.
See Forty-Eight Insulations,
*77 Accordingly, the policyholders’ motion for partial summary judgment is granted. An appropriate order may be submitted.
Notes
. The policyholders have settled with Travelers Insurance Company.
. The sites are: Alburn, Cardinal, Charles George, City Chemical, Clare, Davidson, Enviro-Chem, Keefe, Liquid Disposal, Pagel's, Re-Solve, Silresim, Springfield, Wayne, Cannons-Bridge-water, and Cannons-Plymouth.
. The sites аre: QuVoe, Tinkham Garage, Union, and Kingston.
. The site is Dover landfill. Stuart Affidavit, Exhibit O. Interestingly, Fireman’s Fund alleg-
. The site is Conservation Chemical.
. Wausau and Fireman’s Fund policies provide: This insurance does not apply ... to property damage to (1) property owned or ocсupied by or rented to the insured, (2) property used by the insured, or (3) property in the care, custody or control of the insured or as to which the insured is for any purpose exercising physical control_
The Zurich policy similarly provides:
This policy does not apply ... to injury or destruction of (1) property owned or occupied by or rented to the insured....
. The pollution exclusion is part of every Wau-sau policy effective on or after January 1, 1972. It is part of every Fireman’s Fund policy effеctive on or after November 30, 1973.
. The policies containing pollution exclusions generally cover any property damage caused by an occurrence:
"[0]ccurrence” means an accident, including continuous or repeated exposure to conditions, which results in bodily injury or property damage neither expected nor intended from the standpoint of the insured....
Application of this definition hinges upon whether the policyholders expected or intended property damage.
