**Clean Water Act; Availability of List Decisions** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Notice of Availability and Request for Public Comment.

**SUMMARY :**  This action announces the availability of the Environmental Protection Agency’s (EPA) proposed decision identifying water quality limited segments and associated pollutants in Oregon to be listed pursuant to section 303(d)(2) of the Clean Water Act (CWA). EPA is proposing to add 1004 water quality limited segments to Oregon’s 2010 Section 303(d) list. EPA solicits public comment on these proposed listings. The proposed listings, together with additional information concerning the proposed listings, are available for review on EPA’s Web site.

**DATES :**  Comments must be received on or before April 16, 2012.

**ADDRESSES :**  Comments: Comments on the proposed listing action must be sent electronically or by mail to Jill Gable, 303(d) Listing Program, Office of Water and Watersheds; USEPA Region 10; 1200 6th Ave. Suite 900, OWW–134; Seattle, WA 98101; telephone (206) 553–2582, facsimile (206) 553–0165, email gable.jill@epa.gov. Oral comments will not be considered.

Availability for Review: Copies of the proposed decision concerning Oregon’s 303(d) list which explain the rationale for EPA’s proposed decision can be obtained at EPA Region 10’s Web site at: www.epa.gov/region10/notices/ oregon303d.html, or by writing or calling Ms. Gable at the above address. **FOR FURTHER INFORMATION CONTACT :**  Jill Gable at (206) 553–2582 or gable.jill@epa.gov

. **SUPPLEMENTARY INFORMATION :**  Section 303(d) of the Clean Water Act (CWA) (hereinafter referred to as ‘‘Section 303(d)’’) requires states to identify those waters within their jurisdiction for which effluent limitations are not stringent enough to implement applicable water quality standards, to establish a priority ranking for such waters, and to submit a listing of such waters to EPA (hereinafter referred to as a ‘‘303(d) list’’).

EPA’s Water Quality Planning and Management regulations include requirements for implementation of section 303(d), at 40 CFR 130.7. 40 CFR 130.7(d) requires states to identify water quality limited waters still requiring Total Maximum Daily Loads (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. See 40 CFR 130.7(d).

Section 303(d)(2) also requires that EPA approve or disapprove lists submitted by States. If EPA disapproves a list, EPA must identify waters in the state that do not meet water quality standards. After EPA has identified waters not attaining water quality standards, EPA must issue a public notice seeking comments on the list. See 40 CFR 130.7(d)(2).

On May 24, 2011, the Oregon Department of Environmental Quality (‘‘ODEQ’’) submitted Oregon’s 2010 Section 303(d) list of water quality limited segments (‘‘WQLSs’’) (‘‘Oregon’s 2010 303(d) list’’), to EPA, as part of the Integrated Report submitted by the state to meet the requirements of sections 303(d), 305(b), and 314 of the CWA. On March 15, 2012, EPA sent a letter to ODEQ, in which EPA approved ODEQ’s inclusion of 970 water quality limited segments to Oregon’s 303(d) list and ODEQ’s removal of 927 water quality limited segments from Oregon’s 303(d) list.

In the March 15, 2012 letter to ODEQ, EPA also disapproved Oregon’s decisions not to list 1004 water quality limited segments as impaired, including 321 water quality limited segments that Oregon identified as impaired but failed to list on the Section 303(d) list. EPA has identified these additional water quality limited segment for inclusion on the State’s 2010 Section 303(d) list. These water quality limited segments and associated pollutants as proposed by EPA are identified in Enclosure 3 of the decision document available at the following Web site link: www.epa.gov/ region10/notices/oregon303d.html

.

EPA is providing the public the opportunity to review its proposed decision to list 1004 water quality limited segments to Oregon’s 2010 Section 303(d) list. EPA will consider and respond to public comments in reaching its final decision on the addition of the referenced water bodies and pollutants identified for inclusion on Oregon’s 2010 303(d) list.

Dated: March 2, 2012. Michael A. Bussell, Director, Water Division, EPA Region X.

**Mobility Fund Phase I Auction GIS Data of Potentially Eligible Census**  **Blocks**

**AGENCY :**  Federal Communications Commission.

**ACTION :**  Notice.

**SUMMARY :**  In this document, the Commission’s Wireless Telecommunications and Wireline Competition Bureaus (the ‘‘Bureaus’’) announce the availability of geographic information system (GIS) data for the census blocks potentially eligible for Mobility Fund Phase I support to be offered in Auction 901. This data does not update or replace the list of potentially eligible blocks. Rather, it provides the same data in additional formats and thus just supplements the previously-released data files and interactive map. The Bureaus are taking this step to make the data accessible to more people and to make it easier to use for individual analysis.

**FOR FURTHER INFORMATION CONTACT :**  Lisa Stover of the Auctions and Spectrum Access Division at (717) 338–2868. To request materials in accessible formats (Braille, large print, electronic files, audio format) for people with disabilities, send an email to fcc504@fcc.gov or call the Consumer and Governmental Affairs Bureau at (202) 418–0530 or (202) 418–0432 (TTY). **SUPPLEMENTARY INFORMATION :**  This is a summary of the Mobility Fund Phase I Auction GIS Data for Potentially Eligible Census Blocks Public Notice (Public Notice) released on March 8, 2012. The Public Notice and related Commission documents may be purchased from the Commission’s duplicating contractor, Best Copy and Printing, Inc. (BCPI), 445 12th Street SW., Room CY–B402, Washington, DC 20554, telephone 202– 488–5300, fax 202–488–5563, or you may contact BCPI at its Web site: http://www.BCPIWEB.com. When ordering documents from BCPI, please provide the appropriate FCC document number, for example, DA 12–121. The Public Notice and related documents also are available on the Internet at the Commission’s Web site: http:// wireless.fcc.gov/auctions/901/or by using the search function for AU Docket No. 12–25 on the Commission’s Electronic Comment Filing System (ECFS) Web page at http://www.fcc.gov/ cgb/ecfs/.

1. In the Auction 901 Comment Public Notice , the Bureaus concluded that they would identify census blocks eligible for the Mobility Fund Phase I support to be offered in Auction 901 based on an analysis of the most recent available American Roamer data, from January 2012. A summary of the Auction 901 Comment Public Notice was published in the Federal Register at 77 Fed. Reg. 7152 (Feb. 10, 2012). With the Auction 901 Comment Public Notice, the Bureaus provided, at paragraphs 15, and 18–19, a preliminary list of such blocks using older American Roamer data and stated that they would provide an updated list of potentially eligible census blocks and related updated information upon completion of their analysis of the January 2012 American Roamer data. With the Auction 901 Updated Potentially Eligible Blocks Public Notice, (77 FR 9655, February 17, 2012), the Bureaus provided the updated list of potentially eligible blocks based on January 2012 American Roamer data in electronic format as ‘‘Attachment A’’ files.

2. Concurrent with the release of Auction 901 Updated Potentially Eligible Blocks Public Notice, the Bureaus announced the availability of a map of the updated potentially eligible blocks. The map is an interactive visual representation of data from the updated Attachment A files. The Attachment A files contain more information and generally more detail than is displayed on the map. The map is available at http://wireless.fcc.gov/auctions/901/and at http://www.fcc.gov/maps/.

3. The data formats the Bureaus make available are additional formats of the data as shown in the interactive map. These formats, which are available at http://wireless.fcc.gov/auctions/901/

, are the following:

• Downloadable shapefile

• Web mapping service

• MapBox map tiles

4. The shapefile format is actually four individual files (.dbf, .shp, .shx, and .prj) all with the same prefix. That information is available at: ‘‘Esri Shapefile Technical Description,’’ http://www.esri.com/library/ whitepapers/pdfs/shapefile.pdf. This format is generally recognized as a standard transfer file for GIS data. The shapefile is an accepted transfer in just about every GIS software package.

5. Web mapping service (WMS) is an Open Geospatial Consortium standard for delivering geospatial data over the web. That information is available at http://www.opengeospatial.org/ standards. The WMS data service can be viewed in two ways. First, the data can be viewed by using the URL. Second, most GIS software allows you to add this service as a layer to your session or project.

6. MapBox map tiles are cached map tiles of the data. With this open source software approach, these image tiles can be joined with other MapBox layers to make new maps. This information is available at http://mapbox.com/.

7. For additional information about Auction 901, including an overview of requirements to participate in the auction and proposals for auction procedures, you should consult the Auction 901 Comment Public Notice. As set forth in that public notice, comments were due February 24, and reply comments were due March 9, 2012. As set forth in ‘‘Mobility Fund Phase I Auction; Limited Extension of Deadlines for Comments and Reply Comments on Census Block Eligibility Challenges,’’ comments and reply comments on census block eligibility challenges are due March 16, 2012, and March 26, 2012, respectively. Public notices and additional information about Auction 901 may be found at http://wireless.fcc.gov/auctions/901/.
