B. Residuals Land Application Program (FORM: RLAP 06-16) Application:
Section III, Item 4 states that there is 50.62 pounds of plant available nitrogen (PAN) per dry ton
(lb PAN/DT) of residuals generated based on the January 24, 2022 residuals analysis. This totals
12,655 lb PAN annually at the permitted rate of 250 DT per year (DT/yr). Calculations of the total
PAN uptake for the permitted fields, based on the Realistic Yield Index for the soils and
management practices of these fields (including a 25% reduction of application rates on grazed
fields), suggest that there isn't enough permitted land to maintain agronomic rates at the permitted
dry tonnage with the removal of the 25.5 acres from fields NC-DV-05.
Please address Section 3, Item 6 in the application which requires a plan and schedule to resolve
any known issues that would prevent land application of the proposed residuals due to the violation
of North Carolina Administrative Code.
