ENVIRONMENTAL PROTECTION AGENCY
[FRL-9653-4]
Clean Water Act Section 303(d): Proposed Withdrawal of Nine Total
Maximum Daily Loads (TMDLs)
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of proposed withdrawal of nine TMDLs.
-----------------------------------------------------------------------
SUBJECT: The EPA hereby issues notice of the proposed withdrawal of
nine final Total Maximum Daily Loads (TMDLs) for Chloride, Sulfate, and
Total Dissolved Solids (TDS) for the Bayou de L'Outre Watershed in
Arkansas. The EPA proposes to withdraw the Bayou de L'Outre TMDLs due
to the discovery of inconsistencies in the values used to derive the
flow and load duration curves, resulting in the calculation of TMDLs
which do not accurately reflect the loading capacity of the segments.
Any future withdrawal action will not affect seven final TMDLs
published under the same Federal Register notice (see 76 FR 52947)
which pertain to segments 08040203-010, 08040204-006, and 08040206-015,
-016, -716, -816, -916.
DATES: Comments on the proposed withdrawal action must be submitted in
writing to the EPA on or before April 27, 2012.
ADDRESSES: Comments on the proposed withdrawal action of the Bayou de
L'Outre TMDLs should be sent to Diane Smith, Environmental Protection
Specialist, Water Quality Protection Division, U.S. Environmental
Protection Agency Region 6, 1445 Ross Avenue Dallas, TX 75202-2733, or
emailed to [email protected]. The administrative record files for the
nine TMDLs are available for public inspection at the previously listed
address. Please contact Diane Smith (via mail, email, or by calling
(214) 665-2145) to schedule an inspection or to obtain copies of
relevant supporting documents. Documents from the administrative record
files may also be viewed at http://www.epa.gov/region6/water/npdes/tmdl/index.htm.
SUPPLEMENTARY INFORMATION: The TMDLs were developed under EPA Contract
Number 68-C-02-108. The Federal Register notice of availability,
seeking public comments on the draft TMDLs, was published on December
17, 2007 (see 72 FR 71409). Public comments were received by January
16, 2008, and a response to each comment was provided. The Federal
Register notice of availability for the final TMDLs was published on
August 24, 2011 (see 76 FR 52947). The nine pollutant pairs for Bayou
de L'Outre subject to the proposed withdrawal are as follows.
------------------------------------------------------------------------

The 2008 Arkansas Clean Water Act (CWA) Section 303(d) list of

three Bayou de L'Outre segments addressed by this action. Any future
withdrawal action of the aforementioned TMDLs will not affect the
listing of those segments.
