contributing to exceedances of the criteria; and
(c) The LA for nonpoint sources is to address
anthropogenic sources in the basin such that in-stream concentrations meet the
Class III freshwater DO criteria which, based on the measured concentrations

reduction of TP at sources contributing to exceedances of the
criteria.
(5) Mustang
Ranch Creek. The bacteriological TMDL for Mustang Ranch Creek is 400

contributing to exceedances of the criteria; and
(c) The LA for nonpoint sources is to address
anthropogenic sources in the basin such that in-stream concentrations meet the
fecal coliform criteria which, based on the measured concentrations from the
2001 to 2008 period, will require an 88% reduction of sources contributing to
exceedances of the criteria.
