   Subpart C--Identifying Impaired Waterbodies And Establishing Total 
                       Maximum Daily Loads (TMDLs)
 
Sec. 130.27  How must you format your list of impaired waterbodies?

    (a) Your list of impaired waterbodies must include the following 
four parts:
    (1) Part 1. Waterbodies impaired by one or more pollutant(s) as 
defined by Sec. 130.2(d), unless listed in Part 3 or 4. Waterbodies 
identified as impaired through biological information must be listed on 
Part 1 unless you know that the impairment is not caused by one or more 
pollutants, in which case you may place the waterbody on Part 2 of the 
list. Where the waterbody is listed due to biological information, the 
first step in establishing the TMDL is identifying the pollutant(s) 
causing the impairment. Waterbodies must also be included on Part 1 
where you or EPA have determined, in accordance with 
Secs. 130.32(c)(1)(v), (2)(vii), and (3)(i), that a TMDL needs to be 
revised. Waterbodies that you chose to list pursuant to Sec. 130.25(b), 
because you anticipate that they will become impaired by one or more 
pollutant(s), must be included on Part 1 of your list. A TMDL is 
required for waterbodies on Part 1 of the list.
    (2) Part 2. Waterbodies impaired by pollution as defined by 
Sec. 130.2(c) but not impaired by one or more pollutants. A TMDL is not 
required for waterbodies on Part 2 of the list.
    (3) Part 3. Waterbodies for which EPA has approved or established a 
TMDL and water quality standards have not yet been attained. The 
waterbody must be placed on Part 1 of the list and scheduled for 
establishment of a new TMDL if you or EPA determine that substantial 
progress towards attaining the water quality standard is not occurring.
    (4) Part 4. Waterbodies that are impaired, for which the State, 
Territory, or authorized Tribe demonstrates that water quality standards 
will be attained by the date of submission of the next list as a result 
of implementation of technology-based effluent limitations required by 
sections 301(b), 306, or 307 of the Clean Water Act or other controls 
enforceable by State, Territorial or authorized Tribal or Federal law or 
regulation (including more stringent water quality-based effluent

limitations in NPDES permits). A TMDL is not required for waterbodies on 
Part 4. If a waterbody listed on Part 4 does not attain water quality 
standards by the time the next list is required to be submitted to EPA, 
such waterbody must be included on Part 1 unless you can demonstrate 
that the failure to attain water quality standards is due to failure of 
point source dischargers to comply with applicable NPDES permit effluent 
limitations, which are in effect. TMDLs for waterbodies moved from Part 
4 to Part 1 of the list must be scheduled for establishment in 
accordance with the requirements of Sec. 130.28(b).
    (b) You must identify:
    (1) The pollutant or pollutants causing the impairment for each 
waterbody on Part 1 of the list, or for waterbodies for which the 
impairment is a result of biological information, the pollutant or 
pollutants if known.
    (2) The type of pollution causing the impairment for each waterbody 
on Part 2.
    (3) The geographic location of each waterbody on the list, using the 
National Hydrography Database or subsequent revisions, or a compatible 
georeferenced database.
    (c) Any one of the three reporting formats described in this 
paragraph are acceptable.
    (1) Separate section 303(d) list. You may submit your list as a 
separate four-part section 303(d) list.
    (2) Consolidated section 303(d) list and section 305(b) report. You 
may submit your list as a component of your water quality report 
(section 305(b) report) . You must clearly identify the parts of your 
water quality report you are submitting as your four-part section 303(d) 
list.
    (3) Part 1 waterbodies in section 303(d) report and Parts 2, 3, and 
4 waterbodies in section 305(b) report. You may submit Part 1 of your 
list as a separate section 303(d) list, provided you include Parts 2, 3, 
and 4 of your list as a component of your section 305(b) water quality 
report and clearly identify the parts of your water quality report that 
you are submitting as Parts 2, 3, and 4 of your section 303(d) list.
    (d) EPA will approve or disapprove your four-part section 303(d) 
list regardless of the reporting format that you use.
