  Description:

    Abstract:

      The spatial data and corresponding map represents the State

      of Georgia 2000-2001 assessment of water quality and

      resulting year 2002 305(b)/303(d) lists of waters prepared

      in response to Sections 305(b) and 303(d) of the Clean

      Water Act and in accordance with the United States

      Environmental Protection Agency's (USEPA) implementing

      regulations and guidance. Assessed waterbodys are

      classified as supporting, partially supporting, or not

      supporting their designated uses according to a comparison

      of water quality monitoring results to water quality

      standards and other pertinent information.

    Purpose:

      The purpose of this map and information is to show and

      describe the extent of the waters in Georgia where

      compliance with water quality standards has been assessed,

      and waters are listed as either supporting or not fully

      supporting their designated uses according to the U.S.

      Environmental Protection Agency's 305(b) and 303(d) guidelines.

    Supplemental_Information:

      The source for the information in this map comes from the

      Georgia 2002 305(b)/303(d) list, prepared by the Georgia

      Environmental Protection Division of the Department of

      Natural Resources. The list is prepared in response to

      sections 305(b) and 303(d) of the federal Clean Water Act

      and in accordance with USEPA implementing regulations and

      guidance.

      Section 305(b) requires that each State prepare and submit

      to the Administrator of the United States Environmental

      Protection Agency (USEPA) a biennial report, which describes

      water quality conditions of navigable waters across the State.

      The USEPA provides guidance to the States to establish a

      framework for consistent reporting across the nation. This

      report provides an assessment of the water quality

      conditions in Georgia and includes a description of the

      nature, extent, and causes of documented water quality

      problems.

      Section 303(d) requires that each State identify those

      waters within its boundaries for which effluent limitations

      required by Section 301(b)(1)(A) and Section 301(b)(1)(B)

      are not stringent enough to implement any water quality

      standard applicable to such waters. States are then

      required to establish a total maximum load for each

      pollutant at such a level necessary to implement the

      applicable water quality standard. Georgia’s 305(b)/303(d) list is

      published  biennially as part of the larger publication entitled

      “Water Quality In Georgia”. The 2002 list will appear in the

      2000 – 2001 edition to be published fall 2002.

      Process_Description:

        Process Step 1: Creation of Georgia 2000 305(b)/303(d) List Map

        The State of Georgia 2000 305(b)/303(d) List map was

        developed from an earlier map created by the U.S.

        Geological Survey Center for Spatial Analysis and

        Technology (see source citation for DNR305b Stream Reaches).

        Modifications were made by the Georgia Department of

        Natural Resources Environmental Protection Division (GAEPD)

        to the existing map to create a new map from which the

        Georgia 305(b) Water Quality Assessment for the Year 2000

        map was developed. Modifications included:

        Stream reaches not having an assessment designation of

        supporting, partially supporting, or not supporting (not

        evaluated) were deleted from the spatial database.

        Multiple DLG stream segments representing a single 305(b)

        listed stream reach were combined into a single stream

        segment to reduce the size of the database and improve its

        utility.

        All listed stream reaches depicted using a left and right

        edge of water were represented by a single segment

        corresponding to one of the edges or the centerline.

        Water bodies such as lakes and estuaries represented by

        polygonal entities were added to the coverage. The polygons

        were converted to lines in order for them to reside in the

        same ArcView line theme as the stream reaches.

        The database field structure was modified to correspond

        more closely to the 305(b)/303(d) list.

        After modifying the original map, stream reaches were

        added to the modified map to reflect the current 2000

        305(b) list of waters. Stream reaches were added using the

        following methods:

        305(b) stream reaches were identified and located

        using location description information as well as available

        marked Georgia Department of Transportation county road

        paper maps.

        Using the stream reach location, a line entity was added to

        the 305(b) map. In cases where there were DLG segments to

        represent the 305(b) stream reach, these line segments were

        directly transferred from the DLG coverage to the 305(b)

        map coverage, and multiple DLG segments were combined into

        one segment representing the 305(b) reach. In cases where

        DLG segments were not available to represent the stream

        reach, primarily in cases of smaller streams, the stream

        reach was digitized into the map in the approximate

        location identified.

        For water bodies such as lakes and estuaries, DLG segments

        were used, when available, to define the boundaries of

        water bodies. In some instances, particularly estuaries,

        when DLG segments were not available to define the water

        body boundary, an ellipse was placed in the approximate

        location of the listed waterbody.

        The work performed to modify and update the original

        map was done using MapInfo software. The final map was

        converted from the MapInfo file format to the ArcView shape

        file format using MapInfo's Universal Translator software.

        For database management purposes unique reach identifiers

        were assigned to each 305(b) listed waterbody according to

        the 10-digit hydrologic unit containing the downstream

        limit of the segment.

        The 305(b) map coverage database was checked against

        Georgia's published water quality assessment 305(b) list

        for the year 2000. For some listed waters the Actions to

        Alleviate database field has been truncated due to

        ArcView's 254 character field length limit

        Process_Step:2

        Creation of Georgia’s 2002 305(b)/303(d) List Map

        The process of creating the 2002 List map consisted largely of modifying

        the 2000 list polyline coverage and attribute table to concur with the new 2002

        305(b)/303(d) list document. Significant additions of waterbody reaches was

        accomplished using the same methods and software outlined in the 2000 list process.

        Some reach segments which did not appear on 1:100,000 hydrology coverage were drawn

        in estimated locations. As a final step, a table in dbase format containing the

        entire 2002 305(b)/303(d) list was joined with the polyline coverage in ArcView

        to form the final product.
