WIFIA Private Borrowers

In the letter of interest, the prospective borrower provides information to demonstrate the project’s eligibility, financial creditworthiness, engineering feasibility, and impact on statutory scoring criteria. If EPA selects the project, the prospective borrower is invited to submit an application. EPA will only select projects that it expects might reasonably proceed to closing.

EPA updated its letter of interest and application forms in January 2025. For the remainder of the current funding round, the WIFIA program will continue to accept the earlier letter of interest and application forms, in addition to the updated forms to support borrowers that have already begun working on their letters of interest and applications.

The forms on this page are for private entities and public-private partnerships (P3s), especially those where the revenues from the proposed project will be used as security for the loan. Public entities, such as local governments, water districts, special utility districts, and other entities using taxes or system revenues to secure their loans should use the forms on the WIFIA Application Materials for Public Entities. If you are unsure which forms to use, please reach out to wifia@epa.gov for assistance.
