"WATER QUALITY STANDARDS ATTAINMENT:
AS INDICATED IN THE PREVIOUS SECTION, THE ENDPOINT OF THIS TMDL IS TO ACHIEVE THE WQS BY ELIMINATING ANY OF THE IMPACTS TO AQUATIC LIFE ASSOCIATED WITH EXCESSIVE SUSPENDED SOLIDS AS DESCRIBED IN THE NARRATIVE CRITERIA PERTAINING TO SOLIDS. TSS CAN BE HIGHLY VARIABLE IN STREAM AND RIVER SYSTEMS AND HAVE STRONG LINKAGES TO STREAM DISCHARGE. KANSAS ADMINISTRATIVE REGULATIONS (KAR) SPECIFIES THAT ?SUSPENDED SOLIDS ADDED TO SURFACE WATERS BY ARTIFICIAL SOURCES SHALL NOT INTERFERE WITH THE BEHAVIOR, REPRODUCTION, PHYSICAL HABITAT, OR OTHER FACTORS RELATED TO THE SURVIVAL AND PROPAGATION OF AQUATIC OR SEMIAQUATIC LIFE OR TERRESTRIAL WILDLIFE.?
KDHE ANALYZED 15 YEARS OF TSS DATA AND ASSOCIATED BIOLOGICAL MONITORING DATA. A STRONG THRESHOLD RELATIONSHIP EXISTS AT 50 MG/L MEDIAN TSS, ABOVE WHICH STREAMS ARE UNLIKELY TO SUPPORT A RICH DIVERSITY OF AQUATIC LIFE. THIS TMDL WILL BE ESTABLISHED TO MEET THE ENDPOINT OF REDUCING EXISTING MEDIAN CONCENTRATIONS OF TSS ON THE LOWER REACHES OF BIG CREEK TO THE MEDIAN TSS SEEN AT THE UPSTREAM STATION (43 MG/L) TO ENSURE GOOD BIOLOGICAL CONDITIONS THAT CAN BE FULLY RESTORED ON THE LOWER REACHES.
THE ENDPOINT OF THIS TMDL FOR THE IMPAIRED SEGMENTS ARE GIVEN BELOW.
