(2) Sufficient soil data entered into NASIS to meet each mapping request objective and to populat NASIS
(3) Conventional and Special Symbols Legend
(4) NASIS generated tables and interpretations
(5) Documentation to support field mapping and interpretations is on file in the field office and located by geographic coordinates.
(6) NASIS generated Identification Legend and Classification Legend.
Tab 3 NASIS generated HEL soil lists for each survey area have been prepared, are current, have been adjusted for any 1992 FSA exemptions, and are on file in the FOTG under Tab 3. Includes both “frozen” and “update” lists. Update lists are maintained for the purpose of updating state and national lists. Update HEL lists include soils identified after distribution of the 1990 frozen soil lists. Wind and water equation factor values remain frozen.
