LOADING CAPACITIES ARE EXPRESSED AS LOAD DURATION CURVES WHICH ACCOUNT FOR SEASONAL VARIATION IN FLOW FOR EACH IMPAIRED SEGMENT. THE RELATIONSHIP BETWEEN THE TARGETED POLLUTANT AND THE POLLUTANT CAUSING THE IMPAIRMENT IS DIRECT. 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. THIS TMDL ADDRESSES THE IMPAIRMENTS TO CHRONIC AQUATIC LIFE SUPPORT AND DOMESTIC WATER SUPPLY AND WILL BE PROTECTIVE OF THE ACUTE AQUATIC LIFE CRITERIA. |
