   Subpart C--Identifying Impaired Waterbodies And Establishing Total 
                       Maximum Daily Loads (TMDLs)
 
Sec. 130.25  What is the scope of your list of impaired waterbodies?

    (a) Your approvable list of impaired waterbodies includes, based on 
all existing and readily available water quality-related data and 
information using appropriate quality assurance/quality control:
    (1) Waterbodies that are impaired by individual pollutants, multiple 
pollutants, or pollution from any source, including point sources, 
nonpoint sources, storm water sources for which a National Pollutant 
Discharge Elimination System (NPDES) permit is not required, ground 
water, and atmospheric deposition.
    (2) Waterbodies for which biological information indicates that they 
do not attain and maintain water quality standards.
    (3) Waterbodies that are impaired by point sources only, nonpoint 
sources only, or by a combination of point and nonpoint sources.
    (b) Your list may include, at your option, waterbodies that are not 
impaired, but which, based on expected changes in loadings or 
conditions, you anticipate will become impaired in the next four years.
