Environmental Cleanup Liens

The federal inquiry rule makes a search for environmental cleanup liens one of the three things all appropriate inquiries must include (40 CFR 312.20(a), (a)(3)). The standard gives that search to the user, not to the environmental professional, unless the professional's scope of work is changed to take it on (E1527-21, 4.6.1, 6.1, 6.2.3). Neither names a list of liens to search: the search is made in land title records, or in judicial records where liens are filed there (E1527-21, 5.4, 6.2).

What puts a property on this record

The rule does not define an environmental cleanup lien. The standard's legal appendix, which is nonmandatory, says the rule's preamble describes one as a lien recorded against the property to recover cleanup costs that a state, tribal or federal agency, or another third party, incurred (E1527-21, X1.7.1). The rule requires a search for cleanup liens against the subject property "that are filed or recorded under federal, tribal, state, or local law" (40 CFR 312.25(a)).

The standard defines an environmental lien as a charge or encumbrance on title that secures payment of costs, damages or other obligations owed for cleaning up hazardous substances or petroleum products on a property, response actions included. Its definition takes in liens under CERCLA and like state or local laws (E1527-21, 3.2.29).

The standard's legal appendix describes the federal Superfund lien: costs and damages a liable party owes the United States become a lien on that party's real property, and for the lien to take priority over other secured interests, notice of it must be filed in the office state law designates. Some state Superfund statutes create liens for cleanup costs, the state's among them (E1527-21, X1.7.3.2).

What a listing shows, and what it does not

A lien found by the search shows that a cleanup cost or obligation was secured against the property (E1527-21, 3.2.29). The standard calls liens and activity and use limitations (AULs) distinct instruments with different purposes, and says either one can be a sign that hazardous substances or petroleum products were released, in the past or now (E1527-21, 5.4). Neither the rule nor the standard says what a lien instrument records about the release behind it, or whether the cleanup it secured is finished.

A search answers for the records and years it covered. A title search information report shall cover documents recorded in land title records from 1980 to the present. If it does not review judicial records, it shall state that law or custom in that jurisdiction does not call for a judicial records search to find environmental liens (E1527-21, 6.2.2.1). For the user's search, a lien filed anywhere other than land title or judicial records is not reasonably ascertainable, unless a statute or regulation names that other place for filing it (E1527-21, 6.2.4). The rule itself names no records and no period to search back (40 CFR 312.25).

In a Phase I ESA

The lien search is not among the standard's government record sources (E1527-21, 8.2.2, Table 2). It is one of the user's tasks. The user may rely on title insurance documents prepared for the transaction, such as a title commitment, or on a title search information report, such as a condition of title or an AUL and environmental lien report, that meets the scope the standard sets for one (E1527-21, 6.2.1, 6.2.2, 6.2.2.1).

The professional shall ask the user for the results (E1527-21, 6.1, 6.2.3.1). The user's search adds to, and does not replace, the professional's review of control registries (E1527-21, 6.2.3). The report shall describe whether the professional received the results. The professional need only say whether the user supplied title records and whether the user found liens or AULs, and need not evaluate those records or the user's conclusions (E1527-21, 6.2.3.2). The report also states whether the user reported a lien encumbering the subject property (E1527-21, 12.3). If the user does not pass the information on, the professional should consider what its absence means, under the provision on the Conclusions (E1527-21, 6.1, 12.7).

Where the user engages the professional to make the search, the report identifies its date (E1527-21, 4.6.1). Whoever makes it, the search is one of the components to be done, or brought up to date, in the 180 days before the date of acquisition (40 CFR 312.20(b)(2); E1527-21, 4.6.2).

Before the site visit, the owner, the key site manager and the user are asked for any agency notices or correspondence about environmental liens encumbering the subject property (E1527-21, 10.8, 10.8.1.12). A user who actually knows of a lien should tell the professional before the site reconnaissance (E1527-21, 6.4).

Where a lien is found, the answer turns on what it secures: which cleanup, at whose cost, under which law. It then turns on what release lay behind it, and on what the agency file and other records show of that cleanup and of any controls it left. A control found with the lien is weighed under the standard's definition of an AUL (E1527-21, 3.2.2); see activity and use limitations. If the professional concludes that hazardous substances or petroleum products are present or likely present at the subject property because of a release or a likely one, or present under conditions posing a material threat of a future release, then unless judged a de minimis condition or a historical REC, the REC is listed in the Conclusions, and the professional should give an opinion on additional investigation, if any (E1527-21, 3.2.20, 3.2.39, 3.2.73, 12.7, 12.8).

What the federal rule says

All appropriate inquiries must include a search for the existence of environmental cleanup liens against the subject property that are filed or recorded under federal, tribal, state, or local law.

40 CFR 312.25(a), edition revised as of July 1, 2025

The rule covers those seeking a liability protection and those assessing a site with a grant under CERCLA section 104(k)(2)(B) (40 CFR 312.1(b)). They must conduct the search "if not otherwise obtained by the environmental professional" (40 CFR 312.22(a)(1)), and may give the results to the professional (40 CFR 312.22(a)). Lien information they collect themselves "may be provided to the environmental professional or retained by the applicable party" (40 CFR 312.25(b)). The rule lets the procedures of E1527-21 be used to comply with 312.23 through 312.31, the lien search among them (40 CFR 312.11(a)).

Where the record is kept

Land title records are recorded in systems that state statutes create, ordinarily administered in the property's local jurisdiction, usually the county (E1527-21, 3.2.45); the legal appendix says the county recorder's office, or a custodian by a similar name, stores them (E1527-21, X1.7.2). In some jurisdictions judicial records, not land title records, hold environmental lien records (E1527-21, 5.4). The standard's legal appendix says state laws differ but commonly have federal liens filed in the county recorder's office, that EPA guidance has its staff file lien notices as state law directs and, where in doubt, in the local records office and the United States district court as well, and that notice of a state Superfund lien is often filed the same way (E1527-21, X1.7.3.2).
