Dry Cleaner cleanup site — Restorical Research
Triangle Mall Shopping Center
Longview, Cowlitz County

Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Triangle Mall Shopping Center in Longview operated as a commercial hub dating back to the 1950s, with at least two dry cleaning tenants — Triangle Cleaners and One-Hour Martinizing Dry Cleaner — among its operators. Two distinct plumes of tetrachloroethylene (PCE), along with trichloroethylene (TCE) and dichloroethylene (DCE), were identified in soil and groundwater at the property in 2003. The former mall building has since been demolished, with planned foundation removal, regrading, and permitting for dewatering discharge underway as part of redevelopment; the site was recommended for the Voluntary Cleanup Program in 2008 but had not yet entered the program as of 2025. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

Why Historical Insurance Policies May Be Accessible

Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.

Dry cleaning operations at this property began in the 1950s — more than three decades before 1986, when occurrence-based Commercial General Liability policies routinely carried no effective pollution exclusion. The two PCE plumes and associated chlorinated breakdown products documented in soil and groundwater here are the direct legacy of those historical operations. Historical carriers who issued CGL policies to Triangle Cleaners, One-Hour Martinizing, or the mall operators during that pre-1986 window may be obligated to fund the investigation, dewatering, source removal, and remediation costs the property has yet to fully incur.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
