5. Part 608

 

608.08 (a) - Under Scheduler attributes, add the following: The total acres of the soil survey area is the same as used in the Natural Resource Inventory (NRI) state total.

608.10 (b) - Replace the current paragraph with the following: The operational status categories are displayed on the Status of Soil Surveys map in the following colors: Published (F), dark green; Project (P1), yellow, indicating that the field mapping is in progress or Project (P2), light green, indicating that the field mapping is complete; Nonproject (N), white; Out-of-Date (D), red; Update (U1), blue, indicating that the field mapping is in progress; and Update (U2), orange, indicating that the field mapping is complete.
 

6. Part 610

610.06 (b) (3) - Change the general manual reference from 402.4 (c) to 402.5 (e)
 

7. Part 617

617.06 - Replace the last two paragraphs with the following:

The Memorandum of Understanding is to state which interpretations are to be made for a soil survey area. The MLRA office, state soil scientist, and cooperators should agree on whether interpretations are generated for miscellaneous land types and minor soil components. Entry of data and preparation of soil interpretations for miscellaneous areas are encouraged. Omission of data elements is by joint consensus of the MLRA office, state soil scientist, and cooperators.

Data elements used as criteria in an interpretation must be completely populated in order to generate reliable interpretations.

Data elements are to be completely populated for major soil components including map unit components classified as higher taxonomic categories. The MLRA office, state soil scientist, and cooperators should reach a joint decision for special situations where it is not practical to populate data elements for map unit components classified at a higher taxonomic category than soil series. If the range of properties is too wide for interpretations, these areas may not meet the requirements of the user defined needs of the survey.

 

8. Part 618

618.48 (c), 2nd paragraph - Replace 2nd, 3rd, and 4th sentences with the following: In general, soils that are either highly alkaline or highly acid are likely to be corrosive to steel. Soils that have pH < 5.5 are likely to be corrosive to concrete. Soils that have pH > 8.5 are likely to be highly dispersible, and piping may be a problem.
 

9. Part 627

627.07 - Add "can be" to the first sentence: Phases can be used to create groupings ...

627.07 (a) (4) (ii) - Add "commonly": Surface phases are commonly used if stones, boulders, ...

627.09 - Change the first sentence to the following: Each map unit is given a name that accurately and uniquely identifies the unit within the legend used.
 

10. Part 631

631.07 (a)

  • First sentence - Change "over 20,000" to more than 23,000
  • Second sentence - Change "over 800" to more than 600
  • Add to the end of the paragraph - the internet, or CD-ROM
     

11. Part 647

647.07 (m) (3) - Replace the first paragraph with the following: Statistics are generated for each quadrangle in the soil survey area and for the survey area. The acreage statistics are generated by UTM projection. In addition to quality control, acreage statistics replace the grid dot counts or planimetered acreage normally performed. These statistics are not submitted as a part of SSURGO. Discrepancies of more than 10 percent of the total between the Natural Resource Inventory (NRI) total and spatially determined totals are noted in the SSURGO review. The state soil scientist and MLRA Office leader review and decide where adjustments are needed.

Exhibit 647-11

  • Identification Information Section, under Description, first paragraph - change the first two sentences to the following: This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by ...
  • Identification Information Section, under Description, second paragraph - change the third sentence to the following: A special soil features layer (point and line features) is optional.
  • Identification Information Section, under Description, third paragraph - Replace the paragraph with the following: Purpose: SSURGO depicts information about the kinds and distribution of soils on the landscape. The soil map and data used in the SSURGO product were prepared by soil scientists as part of the National Cooperative Soil Survey.
  • Identification Information Section, under Cross Reference - Replace the last paragraph with the following: Purpose: This soil survey depicts information about the kinds and distribution of soils on the landscape. The soil map and data used in the SSURGO product were prepared by soil scientists as part of the National Cooperative Soil Survey.
  • Data Quality Information Section, under Attribute Accuracy - At the end of the second paragraph, add the following:
    Edge Match Statements: Edge matching of digital data is described in terms of accuracy of matching of feature edges, feature labels, and descriptive attributes between quadrangles or data sets. In SSURGO, all three are required to match between adjacent quadrangles within the survey. Only the soil survey boundaries are required to match between surveys. Examples of edge match statements for adjacent soil surveys:

    The quadrangles in this soil survey are not edge matched to quadrangles in adjacent soil surveys.

    The quadrangles in this soil survey are edge matched to quadrangles in adjacent soil surveys.

    The quadrangles in this soil survey are edge matched to quadrangles in the Alpha Soil Survey, but are not edge matched to those in the Beta or Gamma Soil Surveys.

    Feature edges and descriptive attributes of quadrangles in this soil survey are matched to those in adjacent soil surveys. Feature labels do not match.

  • Data Quality Information Section, under Attribute Accuracy, following the paragraph on Completeness Reporting - Replace the three paragraphs with the following:
    Soil scientists identify small areas of soils or miscellaneous (nonsoil) areas that have properties and behavior significantly different than the named soils in the surrounding map unit. These minor components may be indicated as special features. If they have a minimal effect on use and management, or could not be precisely located, they may not be indicated on the map.

    Specific National Cooperative Soil Survey standards and procedures were used in the classification of soils, design and name of map units, and location of special soil features. These standards are outlined in Agricultural Handbook 18, Soil Survey Manual, 1993, USDA, SCS; Agricultural Handbook 436, Soil Taxonomy, Soil Survey Staff, 1975, USDA, SCS; and all Amendments; Keys to Soil Taxonomy, Soil Survey Staff, (current issue); National Soil Survey Handbook, title 430-VI, 1996.

    The actual composition and interpretive purity of the map unit delineations were based on data collected by scientists during the course of preparing the soil maps. Adherence to National Cooperative Soil Survey standards and procedures is based on peer review, quality control, and quality assurance. Quality control is outlined in the memorandum of understanding for the soil survey area and in documents that reside with the Natural Resources Conservation Service state soil scientist. Four kinds of map units are used in soil surveys: consociations, complexes, associations, and undifferentiated groups.

     
  • Under Explanation of Template Metadata Numbered Elements Section - Change the zip code in item 15 to 50309-2180
  • Under Explanation of Template Metadata Numbered Elements Section - Add the following as 20a:

    20a - Edge Match Statements: Edge matching of digital data is described in terms of accuracy of matching of feature edges, feature labels, and descriptive attributes between quadrangles or data sets. In SSURGO, all three are required to match between adjacent quadrangles within the survey. Only the soil survey boundaries are required to match between surveys. Examples of edge match statements for adjacent soil surveys:

The quadrangles in this soil survey are not edge matched to quadrangles in adjacent soil surveys.

The quadrangles in this soil survey are edge matched to quadrangles in adjacent soil surveys.

The quadrangles in this soil survey are edge matched to quadrangles in the Alpha Soil Survey, but are not edge matched to those in the Beta or Gamma Soil Surveys.

Feature edges and descriptive attributes of quadrangles in this soil survey are matched to those in adjacent soil surveys. Feature labels do not match.
