(A) The department shall promulgate regulations relating to land application rates for animal waste for animal feeding operations of a capacity for more than 420,000 pounds of normal production animal live weight at any one time. These rates must be based on the waste's impact on the environment, animals, and people living in the environment. In developing annual pollutant loading rates and cumulative pollutant loading rates, the department shall consider:

1. (1) soil type;
2. (2) type of vegetation growing in land-applied area;
3. (3) proximity to 100-year flood plain;
4. (4) location in watershed;
5. (5) nutrient sensitivity of receiving land and waters;
6. (6) soil and sediment tests of receiving land and waters;
7. (7) nutrient, heavy metal, and pollutant content of the waste being applied;
8. (8) proximity to a State Designated Focus Area; Outstanding Resource Water; Heritage Corridor; Historic Preservation District; state or national park or forest; state or federal research area; and privately-owned wildlife refuge, park, or trust property;
9. (9) proximity to other point and nonpoint sources;
10. (10) slope of land;
11. (11) distance to water table or ground-water aquifer;
12. (12) timing of waste application to coincide with vegetative cover growth cycle;
13. (13) timing of harvest of vegetative cover;
14. (14) hydraulic loading limitations; and
15. (15) soil assimilative capacity;
16. (16) type of vegetative cover and its nutrient uptake ability;
17. (17) method of land application.
