Information Collection Requests

An ICR is a set of documents that describe reporting, record keeping, survey or other information collection requirements imposed on the public by EPA. The ICR provides an overview of the collection and estimates the cost and time for the public to respond. The public may view an ICR and submit comments on it at any time. TRI ICRs are resubmitted to the Office of Management and Budget (OMB) for approval every 2-3 years.

Current TRI ICR Renewal

In compliance with the Paperwork Reduction Act (PRA), EPA has received OMB approval to consolidate and renew the three ICRs (2070-0225, 2070-0206, and 2070-0216) and renew TRI reporting forms for 3 years.
