The memo includes guidance on handling requests submitted after May 3, 2013, the compliance date for many compression ignition engines. The memo can be accessed at

On June 28, 2013, EPA granted reconsideration of three issues raised in petitions for reconsideration of the January 30, 2013 final amendments to the 2010 RICE NESHAP. EPA’s letters to the petitioners can be accessed at
