## Abstract

EPA issued a final rule in the Federal Register issue of January 7, 2011, concerning testing of certain high production volume (HPV) chemical substances to obtain screening level data for health and environmental effects and chemical fate. This document is being issued to correct a typographical error concerning the required date of submission for letters of intent to test and exemption applications. The correct date by which EPA must receive a letter of intent to test or an exemption application from manufacturers (including importers) in Tier 1 is March 9, 2011.
