Environmental Protection Agency

The EPA's procurement supplement.

Last reviewedJune 7, 2026Version v1

In plain terms. EPAAR is the Environmental Protection Agency's supplement to the FAR, adding EPA-specific contract rules.

Who it applies to. Contractors serving the EPA.

What it requires. Meet the FAR baseline, then EPAAR additions. EPA work involves regulatory, scientific, and some confidential business information, so expect safeguarding terms appropriate to that data.

Why it matters. Confidential business and regulatory data on EPA contracts brings standard protection obligations.

Citation. EPAAR, the Environmental Protection Agency Acquisition Regulation supplement to the Federal Acquisition Regulation (FAR), codified in the FAR System at Title 48 of the C.F.R.
