Variable Load Reductions
Highest Priority Issues Short Creek: Zn, Cd @ normal to high Q Turkey Creek: Zn, Cd @ normal to high Q Center Creek: Zn, Cd @ normal to high Q;
Pb @ normal Q Shawnee Creek: Pb @ normal Q Shoal Creek: Zn @ very high Q Baxter Springs: Pb @ normal to high Q;
Zn @ high to very high Q
Load Reduction Strategy
1. Tributary Reductions for Self & Baxter Springs
2. Reductions on Other Tribs – e.g.; Willow Creek
3. Removal of In-Channel Sediments
4. Potential Dredging of Empire Lake
TMDL Timeline
Next Week: Submission to EPA 2005-2008: Ongoing Remedial
Actions 2008: Reopen TMDL – NRDA data;
effluent monitoring; establish WLAs 2009: Begin targeted sediment
removal 2013: Revisit TMDL; note progress
