## Abstract

EPA has approved by letter certain modifications to test standards and schedules for chemical testing programs under section 4 of the Toxic Substances Control Act (TSCA). These modifications, requested by test sponsors, will be incorporated in the respective test rules or enforceable testing consent agreements/testing consent orders. Because these modifications do not significantly alter the scope of a test or significantly change the schedule for its completion, EPA approved these requests without seeking public notice and comment. EPA annually publishes a rule describing all of the modifications granted by letter for the previous year.
