[Code of Federal Regulations] [Title 40, Volume 23] [Revised as of July 1, 2006] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR176.13] [Page 277] TITLE 40--PROTECTION OF ENVIRONMENT CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED) PART 176_TIME-LIMITED TOLERANCES FOR EMERGENCY EXEMPTIONS--Table of Contents Sec. 176.13 Modification of a time-limited tolerance. If additional emergency or crisis exemptions are authorized that would extend use beyond the date originally authorized, or if EPA determines that the duration of a time-limited tolerance is insufficient to allow treated commodities to clear the channels of trade, EPA may modify the time-limited tolerance by publication of a final rule in the Federal Register. EPA will use the same criteria and procedures for modification as for establishing tolerances under this part.
