Sec.  610.14  Use of USLE, RUSLE, and WEQ.

    (a) All Highly Erodible Land (HEL) determinations are based on the 
formulas set forth in 7 CFR Sec.  12.21 using some of the factors from 
the USLE and WEQ and the factor values that were contained in the local 
Field Office Technical Guide (FOTG) as of January 1, 1990. In addition, 
this includes the soil loss tolerance values used in those formulas for 
determining HEL. The soil loss tolerance value is used as one of the 
criteria for planning soil conservation systems. These values are 
available in the FOTG in the local field office of the Natural Resources 
Conservation Service.
    (b) RUSLE will be used to:
    (1)(i) Evaluate the soil loss estimates of conservation systems 
contained in the FOTG.
    (ii) Evaluate the soil loss estimates of systems actually applied, 
where those systems were applied differently than specified in the 
conservation plan adopted by the producer or where a conservation plan 
was not developed, in determining whether a producer has complied with 
the HEL conservation provisions of the Food Security Act of 1985, as 
amended, 16 U.S.C. Sec.  3801 et seq., set forth in 7 CFR Part 12; and
    (2) Develop new or revised conservation plans.
