SUMMARY OF 2007-2011 ANNUAL ENTITY LOADS RELATIVE TO EXISTING

ALLOCATIONSTampa Bay

Nitrogen Management Consortium

March 14, 2014

OVERVIEW

• Following slides provide comparison of estimated loads for 2007-2011 to allocations developed for 2009 RA

• Handouts provide annual load estimates by entity

• Exceedence calculated as difference between 2007-2011 average and allocation, so that positive exceedence is load greater than allocation.

• Following tables provide exceedences sorted within each loading source group (set point sources, hydrologically affected point sources, MS4s, and other nonpoint source) for each segment
