Subpart A - General 



512.02(g) (2) 



Notify the producer that no determination was made for these lands and 

 that there may be wetland on these areas. 



(e) Use of off site procedures . Where adequate information 

 exists, the use of off site procedures is encouraged to make wetland 

 determinations. Dociiment the information used for off site 

 determinations, such as aerial photographs, wetland maps, soil 

 surveys, and other data as well as the interpretations made from such 

 information. SCS wetland inventory maps may be used to make office 

 wetlemd determinations. 



(f) Use of onsite determinations . 



(1) Make onsite determinations if information is inadequate 

 to make off site wetland determinations; and for all converted wetland 

 violations. 



(2) Point Intercept Sampling Techniques . Where wetland 

 vegetation cannot be determined through routine investigations, use 

 the Point Intercept Sampling Procedure in 7 CFR Part 12 (Appendix 

 518.03). Keep the worksheet and calculations to facilitate future 

 determinations and to form a basis for the wetlemd soil plant 

 correlation data base. 



(g) Use of wetland inventories . State conservationists may 

 authorize wetland inventories in areas that have significant scattered 

 areas of wetlands. Inventories can facilitate making individual 

 wetland determinations in a consistent and timely manner. Wetlemd 

 inventories are usually prepared by trained photo interpretation teams 

 using a combination of ASCS 35 mm slides, aerial photographs, soil 

 surveys, U.S. Fish and Wildlife Service (FWS) wetland maps, and other 

 data. States should give special attention to ensure that inventory 

 tools provide the high degree of quality necessary to make correct 

 wetland determinations in the office. If this is not the case, onsite 

 determinations must be made.

(1) Mapping conventions . States should develop mapping 

 conventions for wetland inventories, with FWS consultation (See 

 Section 512.50) and national technical center (NTC) concurrence, prior 

 to starting the inventory. Wetland inventories must be based on field 

 tested mapping conventions used to interpret off site information. 



(2) Review . District conservationists (DCs) must review 

 wetland inventories for completeness and accuracy. The DC may add, 

 revise, or delete wetlands based on local knowledge, input from 

 farmers, and additional information. The state conservationist (STC) 

 must approve the inventory in writing for each field office before it 

 is used in making wetland determinations.
