(3) A nutrient management plan shall contain sufficient documentation to demonstrate that manure and associated nutrients will be managed:
- (A) In compliance with this part; and
- (B) With the expectation that proper management of those nutrients will be protective of the waters within the state.
- (4) The Department of Agriculture shall require proof of land ownership or of contractual agreements for use of the land as a land application site.
(5)
- (A) The facility nutrient management plan shall be reviewed annually by the operator.
(B) An updated nutrient management plan shall be submitted to the Department of Agriculture:
- (i) When significant changes are made; or
- (ii) As required by the Department of Agriculture.
- (C) The updated nutrient management plan shall include soil samples and analysis as required by this part.
- (6) The nutrient management plan must be updated by the operator every five (5) years.
(7) The operator shall determine that the land application sites proposed for the nutrient management plan are not currently:
(A) Permitted by:
- (i) The Department of Agriculture; or
- (ii) The Division of Environmental Quality; or
- (B) Used by another user.
(f) Land application requirements.
- (1) Manure applications shall be evenly distributed over application sites at the rates specified in nutrient management plans.
(2) Land application of manure shall not be undertaken when:
(A) Soil is:
- (i) Saturated;
- (ii) Frozen; or
- (iii) Covered with ice or snow; or
- (B) Significant precipitation is reasonably anticipated in the next twenty-four (24) hours.
(3)
(A) Manures shall not be applied:
- (i) On slopes with a grade of more than fifteen percent (15%); or
- (ii) In any manner that will allow the manure to:
- (a) (a) Enter waters of the state; or
(b) (b) Run onto adjacent property without the written consent of the affected adjacent property owner.
(B) An exception to the slope requirement will be permitted if:
(i) Manure is incorporated into the soil; and
- (ii) Additional best management practices are applied to the Arkansas Phosphorus Index so that manures do not exit application areas.
(4)
