Operating in accordance with an SWCD approved plan for Highly Erodible Lands (HEL) developed for the purpose of complying with the current US Department of Agriculture (USDA) farm program legislation; and farming non-HEL cropland in a manner that meets the requirements of an approved USDA HEL compliance plan for similar cropland soils in the county; or

(C)

Farming such that the predicted sheet and rill erosion rate does not exceed 5 tons/acre/year, as estimated by the Revised Universal Soil Loss Equation (RUSLE); or

Operating consistent with a Soil and Water Conservation District (SWCD) approved conservation plan that meets Resource Management Systems (RMS) quality criteria for soil and water resources; or

(B)
