Comfort/Status Letters Guidance
The Agency’s comfort/status letter policy provides recommendations and model letters for the U.S. Environmental Protection Agency (EPA) Regions to use when responding to parties interested in reusing and/or redeveloping contaminated, potentially contaminated, and formerly contaminated property (“impacted properties”).
In 2019, EPA issued a revised comfort/status letter policy, which provides the background and purpose of EPA issuance of Superfund comfort/status letters and describes the intended use of these letters under the authority of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
Attached to the 2019 policy are four updated model comfort/status letters:
- Federal Superfund Interest Comfort/Status Letter;
- No Current Federal Superfund Interest Comfort/Status Letter;
- No Previous Federal Superfund Interest Comfort/Status Letter; and
- State Action Comfort/Status Letter.
In 2021, EPA issued a memorandum transmitting two updated model comfort/status letters and three new model comfort/status letters that are consistent with the 2019 policy.
