Clean Water Act Section 303(d): Availability of List Decisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of The Environmental 
Protection Agency's (EPA) Responsiveness Summary Concerning EPA's March 
10, 2015 Public Notice of Proposed Decisions to Add Waters and 
Pollutants to Louisiana's 2014 Section 303(d) List.
    On March 10, 2015 EPA published a notice in the Federal Register at 
Volume 80, Number 46, page 12628 providing the public the opportunity 
to review its decision to partially approve and proposal to partially 
disapprove Louisiana's 2014 Section 303(d) list. Specifically, EPA 
approved Louisiana's listing of 279 waterbody-pollutant combinations, 
and associated priority rankings. EPA proposed to disapprove 
Louisiana's decisions not to list 43 water quality limited segments and 
associated pollutants constituting 93 waterbody-pollutant combinations. 
EPA also proposed to add these waterbody-pollutant combinations to the 
2014 Section 303(d) list because applicable numeric water quality 
standards were not attained in these segments for one of the following 
parameters: Dissolved oxygen (marine criterion); turbidity; and 
minerals (individually or a combination of sulfates, chlorides, and/or 
total dissolved solids).
    Based on the Responsiveness Summary, EPA finds no new information 
or persuasive arguments as to why the 43 water quality limited segments 
should not be added to the 2014 Louisiana Section 303(d) list as 
proposed. Therefore, EPA is taking Final Action on the addition of 43 
water quality limited segments and associated 93 waterbody-pollutant 
combinations to the final Louisiana 2014 Section 303(d) list. The basis 
for these decisions is described in EPA's Decision Document for the 
Louisiana 2014 Section 303(d) list, available at http://www.epa.gov/region6/water/npdes/tmdl/index.htm.

ADDRESSES: Copies of EPA's Responsiveness Summary Concerning EPA's July 
21, 2015 Public Notice of Final Decisions to Add Waters and Pollutants 
to Louisiana's 2014 Section 303(d) list can be obtained at EPA Region 
6's Web site at http://www.epa.gov/region6/water/npdes/tmdl/index.htm#303dlists, or by writing or calling Evelyn Rosborough,

SUPPLEMENTARY INFORMATION: Section 303(d) of the Clean Water Act (CWA) 
requires that each state identify those waters for which existing 
technology-based pollution controls are not stringent enough to attain 
or maintain state water quality standards. For those waters, states are 
required to establish Total Maximum Daily Loads (TMDLs) according to a 
priority ranking.
    EPA's Water Quality Planning and Management regulations include 
requirements related to the implementation of Section 303(d) of the CWA 
(40 CFR 130.7). The regulations require states to identify water 
quality limited waters still requiring TMDLs every two years. The list 
of waters still needing TMDLs must also include priority rankings and 
must identify the waters targeted for TMDL development during the next 
two years (40 CFR 130.7).
    Consistent with EPA's regulations, Louisiana submitted to EPA its 
2014 listing decisions under Section 303(d) on August 19, 2014. On 
February 26, 2015, EPA approved Louisiana's 2014

listing of 279 water body-pollutant combinations and associated 
priority rankings, and proposed to disapprove Louisiana's decisions not 
to list 43 water quality limited segments and associated pollutants 
constituting 93 waterbody-pollutant combinations. On July 21, 2015, EPA 
finalized the action to disapprove Louisiana's 2014 listing decisions 
not to list 43 water quality limited segments. EPA identified these 
additional waters for inclusion on the 2014 Section 303(d) List.

    Dated: July 21, 2015.

Director, Water Quality Protection Division, Region 6.
