ACTION:

Notice of Availability.

SUMMARY:

This notice announces the availability of EPA's Responsiveness Summary Concerning EPA's April 13, 2011 Public Notice of Proposed Decisions to Add Waters and Pollutants to Louisiana's 2008 Section 303(d) List.

On April 13, 2011 EPA published a notice in the Federal Register at 76 FR 20664-20665 providing the public the opportunity to review its decision to partially approve and proposal to partially disapprove Louisiana's 2008 Section 303(d) List. Specifically, EPA approved Louisiana's listing of 409 waterbody pollutant combinations, and associated priority rankings. EPA proposed to disapprove Louisiana's decisions not to list three waterbodies. These three waterbodies were added by EPA because the applicable numeric water quality standards marine criterion for dissolved oxygen was not attained in these segments.

Based on the Responsiveness Summary, EPA finds no new information or persuasive arguments as to why the three waters should not be added to the 2008 Louisiana Section 303(d) List as proposed. Therefore, EPA is taking Final Action on the addition of three waterbody pollutant combinations to the final Louisiana 2008 Section 303(d) List. The basis for these decisions is described in EPA's Responsiveness Summary and the Record of Decision.

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 2008 listing decisions under Section 303(d) on August 25, 2009. On April 13, 2011, EPA approved Louisiana's 2008 listing of 409 water body-pollutant combinations and associated priority rankings, and proposed to disapprove Louisiana's decisions not to list three waterbodies. On September 28, 2011, EPA finalized the action to disapprove Louisiana's 2008 listing decisions not to list three water quality limited segments. EPA identified these additional waters and pollutants along with priority rankings for inclusion on the 2008 Section 303(d) List.
