for Dissolved Oxygen and Fecal Coliform Proposed for South Fork Forked
Deer River Watershed in southwestern TN: Section 303(d) of the Clean
Water Act requires states to develop TMDLs for waters on their impaired
waters list. TMDLs must determine the allowable pollutant load that the
water can assimilate, allocate that load among the various point and nonpoint
sources, include a margin of safety, and address seasonality.
The following TMDLs have been proposed for South Fork Forked Deer
Oxygen-TMDL Available at www.state.tn.us/environment/wpc/SFFDDO03.pdf
due by March 26, 2001 South Fork Forked Deer River from RM 22.3
to RM 35.1 and South Fork Forked Deer River from RM 35.1 to RM 56.1 are
listed on Tennessee's final 1998 303(d) list as partially supporting designated
use classifications due, in part, to low dissolved oxygen.
TMDL concludes that these river sections are not presently impaired due
to low dissolved oxygen levels. TMDL implementation recommendations include
additional water quality monitoring, a stream survey to refine the water
quality model, and additional CBOD or ammonia loading permitted only if
no adverse impact to dissolved oxygen levels can be demonstrated.
Coliform-TMDL Available at http://www.state.tn.us/environment/wpc/sffdfec3b.pdf
due by April 9, 2001
Fork of the South Fork Forked Deer River, Johnson Creek, and three segments
of the South Fork Forked Deer River (Sumrow Cr. to Nixon Cr., Nixon Cr.
to Mud Cr., and Mud Cr. to Meridian Cr.) are listed on Tennessee's final
1998 303(d) list as not supporting designated use classifications due,
in part, to pathogens associated with urban storm water runoff and agriculture.
The TMDLs require reductions in fecal coliform loading of approximately
72% to 84% in the five listed water bodies.
