§510.50 



This procedure will lead you through a step-by-step method of making 

 wetland 1/ determinations for the Food Security Act In the office. If a 

 wetland determination Is not made, then ID-CPA(FSA)-22, revised 5/88, will 

 be used to document potential for wetlands and that no determination was 

 made. See Exhibit 516.14. The process of making wetland determinations 

 In the office will require the following resources: 



^1. Soil Survey. - ^ 



2. Fish and Wildlife National Wetland Inventory Map (MUI), where 

 available. 



3. ASCS aerial slides (preferably 5 years -- 1981-1985). 

 Step 1: Review soil survey. Identify the following soils: 



1. Named hydrlc map units. 



2. Map units with hydrlc soils as inclusions. 



3. Map units with no hydrlc soils. In nost cases, these can be 

 eliminated from further review. However, these soils may have artificial 

 wetlands (AW) or other oddities which need to be identified. 



The review of the soil survey will provide information on which areas 

 have a potential for wetlands^ 



Step 2: Review FWS NWI maps where available. NWI maps will give an 

 excellent overview of the wetlands la the area. All wetlands on the NWI 

 maps will be considered wetlands for FSA unless review of the ASCS slides 

 does not confirm wetland. This could happen for the following reasons: 



1. Review of the slides does not show basins as having water, hydro- 

 phytlc vegetation, and drowned-out crops. 



2. Wetland has been drained since the NWI photos were taken in 1979. 



Step 3: Review ASCS aerial slides. 5 years of slides should be looked 

 at preferabley 1981-85. Most ASCS slides are taken in June or July. You 

 should keep in mind those years where above or below precipitation when 

 viewing the slides. 



Review the slides for the following information: 



1. Basins with water standing. 



2. Drowned-out crops. 



3. Hydrophytlc vegetation. 



1/ The definition of a wetland for the determination procedure Is 

 explained in the SCS National Food Security Act Manual (512.01).
