Feedlot Permit Program



The consultants listed below have indicated they will provide crop consulting services related to preparing an initial nutrient management plan that is part of the application for permit coverage under the general water pollution control permit for concentrated animal feeding operations or preparing annual nutrient management plans. The DENR does not certify environmental consultants and makes no representations as to any services performed by these companies. Careful consideration should be given to selection of a consultant as services may vary greatly from company to company. Additional nutrient management planners may be found on the Natural Resources Conservation Service's TechReg website at
