Extension of Time to Submit a Study Plan File Name: N/A Attachment Date: 03/17/2015 Please state why the EPA should grant the extension: Harcros Chemicals Inc. submitted a letter of intent for D-gluco-Heptonic acid, monosodium salt, (2.xi.)- [CAS# 31138-65-5] on April 5, 2011. Although testing was completed, EPA found the Acute Toxicity studies on Fish and Daphnia to be inadequate and asked us to repeat these studies and to have the final reports submitted by February 16, 2015. On December 10, 2014 we submitted a request to extend the deadline to March 31, 2015 which EPA approved. Recently we were informed by the testing facility, Harlan Laboratories, that the testing would not be completed until the end of April 2015. We have requested an explanation from Harlan Laboratories for the change in the expected date of completion but have not yet received a response. Therefore, we are requesting that the deadline be extended until May 31, 2015. Please let us know if this extension request is acceptable to EPA. If any further information is required, please do not hesitate to contact me at (913) 621-7802 or at asavini@harcros.com. ChemicalsSEC4 Submission Page 3
