March 13, 2014: The National Pollutant Release Inventory (NPRI) and partners module of the Single Window System is now available for 2013 reporting. The deadline for reporting to the NPRI for the 2013 calendar year is June 1, 2014. Because June 1, 2014 is a Sunday, reports for 2013 will be considered on time if they are submitted by Monday June 2, 2014.
