**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 smith.diane@epa.gov. 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 impaired waters is the current EPA approved list, and includes the 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.

**Notice of Tentative Approval and Opportunity for Public Comment and**  **Public Hearing for Public Water System Supervision Program Revision**  **for Virginia**

**AGENCY :**  Environmental Protection Agency (EPA). **ACTION :**  Notice of Approval and Solicitation of Requests for Public Hearing and Comments.

**SUMMARY :**  Notice is hereby given in accordance with the provision of section 1413 of the Safe Drinking Water Act, as amended, and the requirements governing the National Primary Drinking Water Regulations Implementation, 40 CFR Part 142, that the Commonwealth of Virginia is revising its approved Public Water System Supervision Program. The Commonwealth has adopted the drinking water regulation for the Ground Water Rule (GWR) which will provide for better public health protection by reducing public water system consumers’ risk of microbial illness from drinking water. EPA has determined that the Commonwealth rule meets all minimum federal requirements, and that the Commonwealth revision is no less stringent than the corresponding federal regulation. Therefore, EPA is taking action to tentatively approve these program revisions. All interested parties are invited to submit written comments on this determination and may request a public hearing.

**DATES :**  Comments or a request for a public hearing must be submitted by April 27, 2012. This determination shall become final and effective on April 27, 2012, if no timely and appropriate request for a hearing is received and the Regional Administrator does not elect to hold a hearing on his own motion, and if no comments are received which cause EPA to modify its tentative approval.

**ADDRESSES :**  Comments or a request for a public hearing must be submitted to the U.S. Environmental Protection Agency, Region III, 1650 Arch Street, Philadelphia, Pennsylvania 19103– 2029. Comments may also be submitted electronically to schmitt.ellen@epa.gov. All documents relating to this determination are available for inspection between the hours of 8 a.m. and 4:30 p.m., Monday through Friday, at the following offices:

• Drinking Water Branch, 3WP21, Water Protection Division, U.S. Environmental Protection Agency, Region III, 1650 Arch Street, Philadelphia, Pennsylvania 19103–
