In August 2011, EPA deferred the reporting deadline for a number of Subpart W equation inputs until March 31, 2015.  In October 2014 [FR 63750] , EPA finalized the approach to collecting these deferred inputs and made several minor modifications to the reporting requirements for Subpart W.  As a result, reporters must submit both an expanded set of Subpart W data for Reporting Year 2014 and deferred data elements for Reporting Years 2011, 2012, and 2013 by March 31, 2015.

To accommodate the reporting of Subpart W inputs, EPA has developed:  1) a RY2014 reporting form for Subpart W which includes deferred data elements in 16 source areas and 2) a separate reporting form to collect deferred data for RY2011, RY2012, and RY2013. 

For more information or to download theses Draft reporting forms, please visit: RY2014 Subpart W Preview Materials.

To further assist the reporting community in their evaluation of the reporting tools, EPA will hold a training session addressing these forms on November 20, 2014.  To register for this webinar please use this link:  https://www2.gotomeeting.com/register/253027090
