THE ENDPOINTS ARE SET SUCH THAT AN AVERAGE MONTHLY ATRAZINE EXCEEDANCE OVER 3UG/L WILL OCCUR NO MORE FREQUENTLY THAN ONCE EVERY THREE YEARS IN THE LAKE OR ITS WATERSHED, ANNUAL AVERAGE ATRAZINE CONCENTRATION WILL BE BELOW 3 UG/L IN TUTTLE CREEK LAKE, ITS OUTFALL AND THE STREAMS COMPRISING ITS WATERSHED, AND NO INDIVIDUAL SAMPLE WILL EXCEED THE ACUTE CRITERION OF 170 UG/L. THE LOAD ALLOCATION IN THIS TMDL IS AN EXAMPLE BASED ON THE MEDIAN FLOW DURING MAY TO JUNE. REFER TO THE TMDL FOR SPECIFIC LOADING INFORMATION.
