Orphan Program
Oregon Orphan Program
The Orphan Program of the Oregon Department of Environmental Quality (DEQ) pays for work at orphan sites. DEQ defines these as sites contaminated by a release of hazardous substances that poses serious threats to human health or the environment, where the parties responsible for the contamination are unknown, unable or unwilling to pay for the needed remedial actions. There are two kinds: industrial orphan sites, and solid waste disposal sites funded through the Solid Waste Orphan Site Account, which DEQ shortens to SWOSA.
In a Phase I ESA
ASTM E1527-21 does not name orphan site lists among its standard record sources. An orphan designation says who has been paying for the work, and that changes what a buyer steps into. Six details shape how to read one.
- Unwilling is enough. DEQ says that at highly contaminated sites it may not be prudent to wait months or years while trying to force a party to act. It may use state funds now to reduce or eliminate immediate threats, and later turn to recovering costs from the parties that are liable.
- Unable is decided on financial records. DEQ requests detailed financial information from potentially liable persons who claim an inability to pay, treats it as confidential, and says a person does not have to be bankrupt to be found unable to pay.
- The work may stop at stable. DEQ says its contractors' work continues at least until a site is stabilized and no longer presents significant threats to humans or the environment. Check whether the site also has a no further action decision.
- DEQ may come back for its costs. DEQ says it may later recover part of its costs by negotiating a lump-sum payment or a repayment plan. For private orphan sites paid from the solid waste account, DEQ's sentence reads: "These steps may include billing the responsible party or placing a lien of the property." Ask whether DEQ holds a claim against the property.
- The two kinds are funded differently. DEQ says industrial orphan cleanups have been funded through the sale of long-term bonds, about $38 million since 1992, with the debt repaid from state general funds and hazardous-substance possession fees. Landfill cleanups are financed by the Solid Waste Orphan Site Account, from a fee of $0.13 per ton charged on solid waste disposed in or exported from Oregon.
- DEQ urges an agreement before buying. DEQ says an orphan site can be purchased at any time, but that if it has not been cleaned up it strongly urges the buyer to negotiate a Prospective Purchaser Agreement first, and that knowingly purchasing a contaminated site without one may leave the buyer liable for the full costs of cleanup. See Prospective Purchaser Agreements.
What the record shows
DEQ describes a typical industrial orphan as a property with soil or groundwater contamination where the responsible party has gone out of business and may have left hazardous substances in tanks or drums. A company may also still be operating but be too small to afford the cleanup. Another type is an area-wide site where drinking-water wells have been contaminated but the source is unknown.
For the Solid Waste Orphan Site Account, DEQ lists the conditions a site must meet:
- it is a solid waste disposal site, such as a landfill, an abandoned or illegal dump, a transfer station, a recycling or composting facility, or an incinerator;
- hazardous substances are known or suspected to be present;
- the site poses a threat of releasing them into the environment;
- it is owned or operated by a local government, or is a privately owned orphan site.
DEQ says eligible sites are ranked by how urgent cleanup is, that the highest priority sites are funded each year, and that it cannot approve all eligible projects. Not being funded says nothing about whether a site met the conditions.
Where to look a site up
- DEQ posts no list of industrial orphan sites on the page read. It says to request a current list through its public records request portal.
- DEQ's Solid Waste Orphan Site Account page links a fact sheet and a funding plan for fiscal year 2026. They were not read for this page.
- An orphan site is a cleanup site, so search it in the Your DEQ Online Public Records Portal. DEQ's criteria for entering a site there include likely referral to the Orphan program.
- The Environmental Cleanup Program is at Cleanup.ResolutionCenter@DEQ.oregon.gov and 800-452-4011.
Getting the file
The list of industrial orphan sites comes by public records request, and so does any part of a site's file that is not online. The route is described on the Your DEQ Online and public records requests page.
