((ii)) that has, or that if used to produce an agricultural commodity, would have an excessive average annual rate of erosion in relation to the soil loss tolerance level, as established by the Secretary, and as determined by the Secretary through application of factors from the universal soil loss equation and the wind erosion equation, including factors for climate, soil erodibility, and field slope.

((B)) For purposes of this paragraph, the land capability class or rate of erosion for a field shall be that determined by the Secretary to be the predominant class or rate of erosion under regulations issued by the Secretary.

((C)) ** .—** Not later than 60 days after the date of enactment of this subparagraph, the Secretary shall publish in the Federal Register the universal soil loss equation and wind erosion equation used by the Department of Agriculture as of that date. The Secretary may not change the equations after that date except following notice and comment in a manner consistent with .

((12)) The term “hydric soil” means soil that, in its undrained condition, is saturated, flooded, or ponded long enough during a growing season to develop an anaerobic condition that supports the growth and regeneration of hydrophytic vegetation.

((13)) The term “hydrophytic vegetation” means a plant growing in—

((A)) water; or

((B)) a substrate that is at least periodically deficient in oxygen during a growing season as a result of excessive water content.

((14)) ** .—** The term “Indian tribe” has the meaning given the term in .

((17)) ** .—** The term “livestock” means all animals raised on farms, as determined by the Secretary.

((18)) ** .—** The term “nonindustrial private forest land” means rural land, as determined by the Secretary, that—
